Introduction
Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

Installation instructions
NOTE: Read the FAQ from Post #3 to ensure that you're installing the correct version of TWRP!!

TWRP Image Install method:
Most devices can be updated quickly and easily within TWRP if you already have version 2.8.4.0 or higher installed.
  1. Download the latest version of TWRP appropriate for your device/firmware
  2. Reboot to TWRP
  3. Hit Install and tap the "Install Image" button in the lower right
  4. Browse to the location of the TWRP image on your device and select it
  5. Select recovery from the partition list and swipe to flash

Alternate Installation Method:
Fastboot Install Method:
You will need the platform-tools from the Android SDK on your computer. Find the Android command line tools section on the page linked and install the SDK tools package. From the SDK Manager, download only the platform-tools to get adb and fastboot binaries.

Windows users will need proper drivers installed on their computer. You can try the Naked ADB drivers or the Universal ADB drivers if you don't already have a working driver installed

On your device, go into Settings -> About and find the Build Number and tap on it 7 times to enable developer settings. Press back and go into Developer Options and enable USB debugging. From your computer, open a command prompt and type:
Code:
adb reboot download
You should now be in fastboot mode.

Download the correct image file and copy the file into the same folder as your adb and fastboot binaries. Rename the image to twrp.img and type:
Code:
fastboot flash recovery twrp.img
Code:
fastboot reboot

[*]A huge laundry list of other minor fixes and tweaks[/LIST]
[U]Additional Notes[/U]
[LIST]WARNING: This is our first release in a long time. We have a lot of new and somewhat aggressive changes in this new release. The changes to the graphics back-end may cause some devices to not boot up properly or have other display-related issues. If you are not in a position to reflash an older build of TWRP, then wait until you are or at least wait until others have tried the new version for your specific device. You don’t want to end up with a non-working recovery and have to wait several hours or days to get to a computer to be able to fix it.
[*]Notes for themers: In addition to the updated theme, we have introduced a theme version variable to the TWRP theme system. If the theme version does not match the version that TWRP expects, TWRP will reject the custom theme and load its stock theme. This change will ensure that people who update TWRP without updating their theme will still have a workable recovery. We have removed libjpeg support. The stock theme was only using a jpeg image for the splash / curtain. This change means that any custom themes will no longer be able to use jpeg images. It also means that tools used to repack recovery images with a different curtain / splash will need to be updated to use the new method.
[*]Version number notes: For a while we’ve been using a 4 digit version number and reserved the 4th digit for device-specific updates. For instance, we find and fix a device-specific issue like decryption of data on Nexus 5, we would release that as a 2.8.7.1. After a while, some people would start asking where 2.8.7.1 was for other devices. So, going forward we have decided to change the numbering scheme to 3.0.0-2, etc. Our hope is that this version numbering scheme will more clearly identify that the 4th digit does not indicate a version change for the code base.
[*]We need your help! The bulk of TWRP work is done by 3 people on a volunteer basis. We have pushed most of our device files to our github and we have a gerrit instance. If you have the ability, please help us maintain our official devices and/or add your device to our official device list. Thanks in advance![/LIST]

[U]Additional Notes[/U]
[LIST]Note: As always, be sure your custom theme is up to date (or remove your custom theme) before updating TWRP.
[*]System read only option: Devices that ship with 5.0 and higher as their initial OS are using block level OTA updates. With this style of OTA update, the update script checks to see if the system partition has ever been mounted read/write. Further, the script also usually runs an SHA sum of the entire system partition to detect if any changes have been made. If any changes have been made, the OTA update will refuse to install. Since not all OEMs and devices have factory images available, we have created a new feature in TWRP that detects if the system partition has ever been mounted read/write. If not, you will be prompted asking if you want TWRP to mount system as read/write. If you choose not to allow TWRP to mount as read/write, TWRP won’t prompt to install SuperSU and TWRP won’t try to patch the stock ROM to prevent TWRP from being replaced by stock recovery. The goal of this option is to hopefully allow the user to make a raw system image backup that they can use to get back to a state where they can take OTA updates again.
[*]resize2fs feature: On some devices like the Nexus 6, the factory images include a userdata image that is the proper size only for the 32GB units. If you flash the factory image to a 64GB Nexus 6, the data partition will appear as if it only has the free space of a 32GB device. Using the resize2fs option, TWRP can resize your data partition to take up the full space available. The resize2fs may also be useful to resize system partitions on devices where custom ROM system images don’t take up the full partition space. Lastly, resize2fs may be useful in some cases to reserve the proper space at the end of a data partition for a full disk encryption key, should your partition be formatted incorrectly for some reason.
[*]This new version also marks our first set of full builds using our new jenkins build server. You can track the progress of builds at [url]https://jenkins.twrp.me[/url] and we have taken additional steps to make it easier for device maintainers to step up and submit patches to our gerrit server at [url]https://gerrit.twrp.me[/url] to help us keep devices up to date and working.[/LIST]

Bug Reporting
If you have an issue, the first step is to post a recovery log so we can determine the cause of the issue. This is done in recovery using Advanced -> Copy Log, or adb pull /tmp/recovery.log. Once a log is uploaded we can determine how best to proceed. NOTE: Posts that are reporting bugs or issues without an accompanying recovery log will be ignored! Additionally, providing details about your device setup, including variant, firmware version, and exact steps to reproduce your issue will also be helpful in diagnosing the problem.

If your issue is determined to be a bug, please consider posting it to our github issues log. It's pretty much impossible for us to keep up with the more than 40 threads that we have for the devices that we "directly" support. If you have a significant problem that cannot be answered in this thread, your best bet is to contact us via our website, or find us in our IRC channel below. If you see someone that's struggling, feel free to point it out to us. We need your help to help us keep track of all of our devices! Thanks!

Frequently Asked Questions (FAQ)
1. Why is this device different than my previous HTC device?
  • With the M9, HTC has moved to a block-based OTA system. This means that even mounting system as read-write (as TWRP typically does during startup checks) will nullify the device's ability to take an OTA. Any other changes to the system partition will also cause an OTA to fail (even if that check is removed from the OTA zip) due to "unexpected contents."
2. Which version of TWRP am I supposed to use?
  • For AOSP/LineageOS-based ROMs: The best version to use is 3.4.0-0, the latest official TWRP from twrp.me.
  • For stock-based Marshmallow/Nougat ROMs: The best version to use is 3.2.3-0, from twrp.me.
  • For ROMs older than Marshmallow: The best version to use is 2.8.7.0, from twrp.me.
    NOTE: The 3.x versions of TWRP and newer will not boot on Lollipop firmware.
3. Why is there a "System" backup option and a "System Image" backup option now?
  • The "System" option is the standard tar backup. The "System Image" option is only relevant if your system is unmodified. This allows you to make a fully stock backup that can be restored later to take an OTA.
    • NOTE: If you are using a FAT32-formatted card, a "System Image" backup will fail, due to the 4GB file limit on that format. For a successful System Image backup, NTFS or exFAT-formatted storage must be used (either SD card or USB-OTG)
4. How am I supposed to root?
  • Magisk is the recommended root solution, as it is actively developed and up-to-date. It also allows devices to pass Google's SafetyNet API for working contactless payments. See the below thread for full details.
5. I tried to install x ROM, but it won't boot. Should I use TWRP 2.8.5.0 to flash it?
  • No, you shouldn't. You should use the version of TWRP recommended above. If the ROM updater-script is done properly, even if your device has system mounted read-only, the ROM should still flash fine. If your ROM chef/team has chosen to mount the partitions some other way, then you may have to mount system manually in order for the ROM to flash successfully. This can be done in the Mount menu, by unchecking the "Mount system as read-only" box and then checking the box next to System to mount it. The very act of booting 2.8.5.0 will change the system checksum, making it impossible to get a fully stock backup.
6. So what's the proper procedure to root without breaking OTA?
  • There is no way to take an OTA after you root. However, prior to rooting, you can take a fully untouched system image backup with TWRP, which can be used to restore a fully stock system to the device in order to take an OTA.
7. How do I backup stock recovery prior to flashing TWRP?
  • You can't. The "fastboot boot" command appears to be disabled on the M9's ABOOT, so TWRP must be fastboot flashed over stock recovery. The firmware zip included in the OTA will include a usable stock recovery image. That can be extracted and flashed after stock system is restored so that the OTA can be applied.
    • UPDATE: As of 3.x firmware, the M9 now supports the fastboot boot function from the bootloader! Now you can fastboot boot TWRP, and then select "Recovery" to back up stock recovery.
8. How do I restore stock system so that I can accept an OTA?
  • Check the "Mount system as read-only" box in the Mount menu.
  • Restore stock "System Image" backup (This will only work if you've made a System Image backup prior to making any modifications to /system). As of the official 2.8.6.1 version, it is no longer necessary to fastboot flash the stock system image.
    • NOTE: If you made a stock system backup with one of the Beta TWRP versions, you will have to rename the backup file in the backup folder manually from "system.emmc.win" to "system_image.emmc.win" for the new official TWRP to see it as a "System Image" backup rather than a "System" backup. Otherwise, you'll get an error that the backup can't be restored because system is read-only.
  • Fastboot flash stock recovery (fastboot flash recovery recovery_signed.img)
    • NOTE: It is also possible to restore stock recovery via the TWRP GUI. Rename the stock recovery file to "recovery.emmc.win" and place in the backup folder with the stock system image. Recovery will then show as a restore option. MAKE SURE YOU REALLY WANT TO DO THIS, AS TWRP WILL BE GONE WHEN YOU REBOOT OUT OF RECOVERY!!
  • Reboot to system, install OTA.
9. What if I have an RUU? Do I need to worry about all this OTA nonsense?
  • Not if you don't care about losing all your data. If you're S-ON and have an RUU available for your exact variant (model ID and CID must match) and software number (main version must be the same or newer), then you can get back to a fully stock state by relocking (fastboot oem lock) and flashing an RUU. However, if you'd prefer to take an OTA to keep your data intact, the method stated above is how to do so. Or, you can just run a custom ROM and wait for your ROM chef to update their ROM to the latest software (though you'll still have to find a way to update your firmware if you're not S-OFF)
10. After I go through all this and successfully apply an OTA, how do I make sure I have a clean starting point again?
  • After the OTA is applied and TWRP is flashed, it will once again detect an untouched system, which will mount system read-only and allow you to make a fully stock backup and start the process over again, this time with the new base.
11. How do I get that new stock theme from the Screenshots tab?
12. What if I'm unlocked but unrooted and don't have access to a computer? How can I install TWRP?

TWRP now supports flashing of zips up to 4GB in size!

In order for ROM zips to function properly, ROM devs may need to change the way they're used to performing mount commands in their updater-scripts. Many ROM devs like to use busybox to mount system, like this:
Code:
run_program("/sbin/busybox", "mount", "/system");
However, on the M9, this will not always be effective, due to the variable state of system when booting into TWRP (more information in the below post). The most reliable way to mount system in TWRP is to use the below command:
Code:
run_program("/sbin/mount", "-t", "ext4", "/dev/block/bootdevice/by-name/system", "/system");
Since this calls the mount binary and specifies the proper filesystem of /system, it will work regardless of the mount state of /system within TWRP.

The reason people are having issues booting ROMs flashed without the above command is because custom ROMs typically include a command to format system within the updater-script, like this one:
Code:
run_program("/sbin/mke2fs", "-t", "ext4", "-m", "0", "/dev/block/bootdevice/by-name/system");
Notice that this calls the mke2fs binary directly and specifies the filesystem, so this command will run properly and format system. However, when the script attempts to mount system using the busybox mount command, it's unsuccessful, resulting in a failed ROM install (even though there likely isn't an error message) and an empty system partition. The same command format should be used both to format system and to mount it.

So, the solution is easy - replace your busybox mount commands with the direct version noted above. Running it that way should work regardless of the update-binary used, since it's not running mount directly but calling it (this makes a difference to some binaries for some reason). This will even work in situations where system has been mounted read-only by TWRP (more on that in the below post).

ROM Devs - please consider making this change going forward. The above method will ALWAYS WORK. Please use this and discontinue whatever other methods to mount system that you have previously used, as they will have inconsistent results, leading people to flash old versions of TWRP or blame TWRP for their errors.

I know the M9 is a very different device than we're all used to, and the rules have all changed. Let's all adapt to the change together. :).

UPDATE: Thanks to @nkk71's patch, TWRP now supports flashing of zips up to 4GB in size! However, for this to work, a compatible update-binary must be used that includes the updated code. If AROMA is being used, it must also include the updated code. Fortunately, he has graciously provided these updated binaries pre-compiled for any that need them. They are attached to this post. Everyone please thank him for his work on this!! :) Additional information can be found here.

adb won't find my Device when in recovery mode, why?
. so I copied file to external_sd.
There's no installation of SuperSU in that log.

But if you already have a stock backup, let's do this:
Under Advanced, choose Terminal, press the select button to start it in the root folder, and then type this command:
Code:
mount -t ext4 /dev/block/bootdevice/by-name/system /system
Then run the SuperSU installer zip.

does doing this kills the OTA updates? Or are they killed, cos installing the beta version ?
Yes it will kill OTA ability (but weren't you trying to root?). So will root. But you have a fully intact stock system backup now, so you should be fine.

No, the whole point of the beta version was to leave system intact if it was previously untouched.

That did the trick. now SuperSU got installed.
Thanks for your help.

Now, If I want to go back and want to receive OTAs again, what are the needed steps?
Is flashing the OTA firmeware.zip enough?

You'll need to take the stock system backup you took (from before you rooted) from the TWRP backup folder, rename to system.img, and flash via fastboot to restore stock system (fastboot flash system system.img). That'll restore system to full stock so you can take the OTA (you'll also need to flash stock recovery if you want to do a full OTA update, but the zip itself *should* flash with TWRP and you'll need to flash the firmware manually).

Once the OTA is complete, you can boot into TWRP, take another stock system backup so you have a good starting point for the next OTA, and then either mount system manually to install SuperSU (as above) or flash a custom rooted ROM.

I'm sure you or someone else can put together a guide with the exact steps. After all, this is just a humble recovery thread ;).

Cheers for this and your reasoning is sound, we are very lucky on the M9 to have 401 (at least) RUUs on our device before most have received theirs!

I will check out the new beta shortly but won't be able to tell you if mounting system is disabled for unmodified systems! Got a one sentence description of how you are doing that? :D

Surely a simpler approach to allow SuperSU would be to allow /mount system but hide it from the GUI or via console a warning displayed, but again beyond that myself -but hopefully
@Chainfire will know what to do!

The issue appears to be how the SuperSU zip is mounting system. Since TWRP is mounting system, but read-only, SuperSU thinks it should be writable, and doesn't try further attempts to mount it as such. @Chainfire should be able to find a way around it, though, as ROM zips mount system as ext4 and can then write to system with no issues. It's only an issue until system is mounted once in recovery - in subsequent boots, it will be writable normally.

Hello,
I am wondering if I can do fastboot boot "recovery.img" and do a backup that way to give me a clean untouched copy of my system and recovery imgs. I understand that there is going to be some changes from the old htc ways. Just trying to get something that can get me back to OTA status. With no RUU for T-Mobile yet I want to have a recovery.img as well as system.
Thanks,

Rsotbiemrptson

    Introduction
    Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

    Images


    Installation instructions
    NOTE: Read the FAQ from Post #3 to ensure that you're installing the correct version of TWRP!!

    TWRP Image Install method:
    Most devices can be updated quickly and easily within TWRP if you already have version 2.8.4.0 or higher installed.
    1. Download the latest version of TWRP appropriate for your device/firmware
    2. Reboot to TWRP
    3. Hit Install and tap the "Install Image" button in the lower right
    4. Browse to the location of the TWRP image on your device and select it
    5. Select recovery from the partition list and swipe to flash

    Alternate Installation Method:
    Fastboot Install Method:
    You will need the platform-tools from the Android SDK on your computer. Find the Android command line tools section on the page linked and install the SDK tools package. From the SDK Manager, download only the platform-tools to get adb and fastboot binaries.

    Windows users will need proper drivers installed on their computer. You can try the Naked ADB drivers or the Universal ADB drivers if you don't already have a working driver installed

    On your device, go into Settings -> About and find the Build Number and tap on it 7 times to enable developer settings. Press back and go into Developer Options and enable USB debugging. From your computer, open a command prompt and type:
    Code:
    adb reboot download
    You should now be in fastboot mode.

    Download the correct image file and copy the file into the same folder as your adb and fastboot binaries. Rename the image to twrp.img and type:
    Code:
    fastboot flash recovery twrp.img
    Code:
    fastboot reboot

    [*]A huge laundry list of other minor fixes and tweaks[/LIST]
    [U]Additional Notes[/U]
    [LIST]WARNING: This is our first release in a long time. We have a lot of new and somewhat aggressive changes in this new release. The changes to the graphics back-end may cause some devices to not boot up properly or have other display-related issues. If you are not in a position to reflash an older build of TWRP, then wait until you are or at least wait until others have tried the new version for your specific device. You don’t want to end up with a non-working recovery and have to wait several hours or days to get to a computer to be able to fix it.
    [*]Notes for themers: In addition to the updated theme, we have introduced a theme version variable to the TWRP theme system. If the theme version does not match the version that TWRP expects, TWRP will reject the custom theme and load its stock theme. This change will ensure that people who update TWRP without updating their theme will still have a workable recovery. We have removed libjpeg support. The stock theme was only using a jpeg image for the splash / curtain. This change means that any custom themes will no longer be able to use jpeg images. It also means that tools used to repack recovery images with a different curtain / splash will need to be updated to use the new method.
    [*]Version number notes: For a while we’ve been using a 4 digit version number and reserved the 4th digit for device-specific updates. For instance, we find and fix a device-specific issue like decryption of data on Nexus 5, we would release that as a 2.8.7.1. After a while, some people would start asking where 2.8.7.1 was for other devices. So, going forward we have decided to change the numbering scheme to 3.0.0-2, etc. Our hope is that this version numbering scheme will more clearly identify that the 4th digit does not indicate a version change for the code base.
    [*]We need your help! The bulk of TWRP work is done by 3 people on a volunteer basis. We have pushed most of our device files to our github and we have a gerrit instance. If you have the ability, please help us maintain our official devices and/or add your device to our official device list. Thanks in advance![/LIST]

    [U]Additional Notes[/U]
    [LIST]Note: As always, be sure your custom theme is up to date (or remove your custom theme) before updating TWRP.
    [*]System read only option: Devices that ship with 5.0 and higher as their initial OS are using block level OTA updates. With this style of OTA update, the update script checks to see if the system partition has ever been mounted read/write. Further, the script also usually runs an SHA sum of the entire system partition to detect if any changes have been made. If any changes have been made, the OTA update will refuse to install. Since not all OEMs and devices have factory images available, we have created a new feature in TWRP that detects if the system partition has ever been mounted read/write. If not, you will be prompted asking if you want TWRP to mount system as read/write. If you choose not to allow TWRP to mount as read/write, TWRP won’t prompt to install SuperSU and TWRP won’t try to patch the stock ROM to prevent TWRP from being replaced by stock recovery. The goal of this option is to hopefully allow the user to make a raw system image backup that they can use to get back to a state where they can take OTA updates again.
    [*]resize2fs feature: On some devices like the Nexus 6, the factory images include a userdata image that is the proper size only for the 32GB units. If you flash the factory image to a 64GB Nexus 6, the data partition will appear as if it only has the free space of a 32GB device. Using the resize2fs option, TWRP can resize your data partition to take up the full space available. The resize2fs may also be useful to resize system partitions on devices where custom ROM system images don’t take up the full partition space. Lastly, resize2fs may be useful in some cases to reserve the proper space at the end of a data partition for a full disk encryption key, should your partition be formatted incorrectly for some reason.
    [*]This new version also marks our first set of full builds using our new jenkins build server. You can track the progress of builds at [url]https://jenkins.twrp.me[/url] and we have taken additional steps to make it easier for device maintainers to step up and submit patches to our gerrit server at [url]https://gerrit.twrp.me[/url] to help us keep devices up to date and working.[/LIST]

    Bug Reporting
    If you have an issue, the first step is to post a recovery log so we can determine the cause of the issue. This is done in recovery using Advanced -> Copy Log, or adb pull /tmp/recovery.log. Once a log is uploaded we can determine how best to proceed. NOTE: Posts that are reporting bugs or issues without an accompanying recovery log will be ignored! Additionally, providing details about your device setup, including variant, firmware version, and exact steps to reproduce your issue will also be helpful in diagnosing the problem.

    Frequently Asked Questions (FAQ)
    1. Why is this device different than my previous HTC device?
    • With the M9, HTC has moved to a block-based OTA system. This means that even mounting system as read-write (as TWRP typically does during startup checks) will nullify the device's ability to take an OTA. Any other changes to the system partition will also cause an OTA to fail (even if that check is removed from the OTA zip) due to "unexpected contents."
    2. Which version of TWRP am I supposed to use?
    • For AOSP/LineageOS-based ROMs: The best version to use is 3.4.0-0, the latest official TWRP from twrp.me.
    • For stock-based Marshmallow/Nougat ROMs: The best version to use is 3.2.3-0, from twrp.me.
    • For ROMs older than Marshmallow: The best version to use is 2.8.7.0, from twrp.me.
      NOTE: The 3.x versions of TWRP and newer will not boot on Lollipop firmware.
    3. Why is there a "System" backup option and a "System Image" backup option now?
    • The "System" option is the standard tar backup. The "System Image" option is only relevant if your system is unmodified. This allows you to make a fully stock backup that can be restored later to take an OTA.
      • NOTE: If you are using a FAT32-formatted card, a "System Image" backup will fail, due to the 4GB file limit on that format. For a successful System Image backup, NTFS or exFAT-formatted storage must be used (either SD card or USB-OTG)
    4. How am I supposed to root?
    • Magisk is the recommended root solution, as it is actively developed and up-to-date. It also allows devices to pass Google's SafetyNet API for working contactless payments. See the below thread for full details.
    5. I tried to install x ROM, but it won't boot. Should I use TWRP 2.8.5.0 to flash it?
    • No, you shouldn't. You should use the version of TWRP recommended above. If the ROM updater-script is done properly, even if your device has system mounted read-only, the ROM should still flash fine. If your ROM chef/team has chosen to mount the partitions some other way, then you may have to mount system manually in order for the ROM to flash successfully. This can be done in the Mount menu, by unchecking the "Mount system as read-only" box and then checking the box next to System to mount it. The very act of booting 2.8.5.0 will change the system checksum, making it impossible to get a fully stock backup.
    6. So what's the proper procedure to root without breaking OTA?
    • There is no way to take an OTA after you root. However, prior to rooting, you can take a fully untouched system image backup with TWRP, which can be used to restore a fully stock system to the device in order to take an OTA.
    7. How do I backup stock recovery prior to flashing TWRP?
    • You can't. The "fastboot boot" command appears to be disabled on the M9's ABOOT, so TWRP must be fastboot flashed over stock recovery. The firmware zip included in the OTA will include a usable stock recovery image. That can be extracted and flashed after stock system is restored so that the OTA can be applied.
      • UPDATE: As of 3.x firmware, the M9 now supports the fastboot boot function from the bootloader! Now you can fastboot boot TWRP, and then select "Recovery" to back up stock recovery.
    8. How do I restore stock system so that I can accept an OTA?
    • Check the "Mount system as read-only" box in the Mount menu.
    • Restore stock "System Image" backup (This will only work if you've made a System Image backup prior to making any modifications to /system). As of the official 2.8.6.1 version, it is no longer necessary to fastboot flash the stock system image.
      • NOTE: If you made a stock system backup with one of the Beta TWRP versions, you will have to rename the backup file in the backup folder manually from "system.emmc.win" to "system_image.emmc.win" for the new official TWRP to see it as a "System Image" backup rather than a "System" backup. Otherwise, you'll get an error that the backup can't be restored because system is read-only.
    • Fastboot flash stock recovery (fastboot flash recovery recovery_signed.img)
      • NOTE: It is also possible to restore stock recovery via the TWRP GUI. Rename the stock recovery file to "recovery.emmc.win" and place in the backup folder with the stock system image. Recovery will then show as a restore option. MAKE SURE YOU REALLY WANT TO DO THIS, AS TWRP WILL BE GONE WHEN YOU REBOOT OUT OF RECOVERY!!
    • Reboot to system, install OTA.
    9. What if I have an RUU? Do I need to worry about all this OTA nonsense?
    • Not if you don't care about losing all your data. If you're S-ON and have an RUU available for your exact variant (model ID and CID must match) and software number (main version must be the same or newer), then you can get back to a fully stock state by relocking (fastboot oem lock) and flashing an RUU. However, if you'd prefer to take an OTA to keep your data intact, the method stated above is how to do so. Or, you can just run a custom ROM and wait for your ROM chef to update their ROM to the latest software (though you'll still have to find a way to update your firmware if you're not S-OFF)
    10. After I go through all this and successfully apply an OTA, how do I make sure I have a clean starting point again?
    • After the OTA is applied and TWRP is flashed, it will once again detect an untouched system, which will mount system read-only and allow you to make a fully stock backup and start the process over again, this time with the new base.
    11. How do I get that new stock theme from the Screenshots tab?
    12. What if I'm unlocked but unrooted and don't have access to a computer? How can I install TWRP?

    TWRP now supports flashing of zips up to 4GB in size!

    In order for ROM zips to function properly, ROM devs may need to change the way they're used to performing mount commands in their updater-scripts. Many ROM devs like to use busybox to mount system, like this:
    Code:
    run_program("/sbin/busybox", "mount", "/system");
    However, on the M9, this will not always be effective, due to the variable state of system when booting into TWRP (more information in the below post). The most reliable way to mount system in TWRP is to use the below command:
    Code:
    run_program("/sbin/mount", "-t", "ext4", "/dev/block/bootdevice/by-name/system", "/system");
    Since this calls the mount binary and specifies the proper filesystem of /system, it will work regardless of the mount state of /system within TWRP.

    The reason people are having issues booting ROMs flashed without the above command is because custom ROMs typically include a command to format system within the updater-script, like this one:
    Code:
    run_program("/sbin/mke2fs", "-t", "ext4", "-m", "0", "/dev/block/bootdevice/by-name/system");
    Notice that this calls the mke2fs binary directly and specifies the filesystem, so this command will run properly and format system. However, when the script attempts to mount system using the busybox mount command, it's unsuccessful, resulting in a failed ROM install (even though there likely isn't an error message) and an empty system partition. The same command format should be used both to format system and to mount it.

    So, the solution is easy - replace your busybox mount commands with the direct version noted above. Running it that way should work regardless of the update-binary used, since it's not running mount directly but calling it (this makes a difference to some binaries for some reason). This will even work in situations where system has been mounted read-only by TWRP (more on that in the below post).

    ROM Devs - please consider making this change going forward. The above method will ALWAYS WORK. Please use this and discontinue whatever other methods to mount system that you have previously used, as they will have inconsistent results, leading people to flash old versions of TWRP or blame TWRP for their errors.

    I know the M9 is a very different device than we're all used to, and the rules have all changed. Let's all adapt to the change together. :).

    UPDATE: Thanks to @nkk71's patch, TWRP now supports flashing of zips up to 4GB in size! However, for this to work, a compatible update-binary must be used that includes the updated code. If AROMA is being used, it must also include the updated code. Fortunately, he has graciously provided these updated binaries pre-compiled for any that need them. They are attached to this post. Everyone please thank him for his work on this!! :) Additional information can be found here.

    adb won't find my Device when in recovery mode, why?
    . so I copied file to external_sd.
    There's no installation of SuperSU in that log.

    But if you already have a stock backup, let's do this:
    Under Advanced, choose Terminal, press the select button to start it in the root folder, and then type this command:
    Code:
    mount -t ext4 /dev/block/bootdevice/by-name/system /system
    Then run the SuperSU installer zip.

    Uploaded 2.8.6.2 to the Beta folder.

    Just a minor update that uses the stock exFAT module instead of exfat-fuse for SD card access. Improves performance a bit, is more reliable, and allows apps like AROMA File Manager to access the external SD properly.

    I made sure I changed the version number this time to avoid the confusion the previous beta version seems to have caused. Please let me know if you have any issues with it. Thanks!
