Introduction
Quote:

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

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
Alternate Installation Method (requires prior TWRP installation):
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

  • Update AOSP base to 6.0
  • A huge laundry list of other minor fixes and tweaks
Additional Notes
  • 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!
2.8.7.0:
  • Initial ground work for software drawn keyboard (_that)
  • Fix handling of wiping internal storage on datamedia devices (xuefer)
  • Allow DataManager to set and read values from the system properties (xuefer)
  • Fix crash when taking screenshots on arm64 devices (xuefer)
  • Fix error message after an ORS script completes (Dees_Troy)
  • Fix crashes / error when creating encrypted backups (_that, Dees_Troy)
  • Add system read only option – more details below (Dees_Troy)
  • Add resize2fs and GUI option to run resize2fs (Dees_Troy)
  • Fix crash loop caused by empty lines in AOSP recovery command file (_that)
  • Prevent duplicate page overlays such as multiple lock screens (mdmower)
Additional Notes
  • 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 https://jenkins.twrp.me and we have taken additional steps to make it easier for device maintainers to step up and submit patches to our gerrit server at https://gerrit.twrp.me to help us keep devices up to date and working.

Bug Reporting
Quote:

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 U11 (like the 10, M9 and A9 prior to it), 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." Additionally, see this HTC 10 thread.
2. I decrypted my device and now I don't have signal. Did a TWRP update cause this?
  • No, this is not a TWRP issue. It appears that on the 10, having a decrypted device prevents the SIM card/telephony from initializing, resulting in no mobile signal or data connection. The device comes with forced encryption enabled and currently must remain that way in order for mobile signal/data to work. TWRP does not change or affect any of that.
3. Which version of TWRP am I supposed to use?
  • The best version to use is 3.2.0-0, the latest official TWRP from twrp.me. (Note: Reboot to recovery does not work due to the lack of kernel source code)
4. Why is there a "System" backup option and a "System Image" backup option now?
  • The "System" option is the standard tar backup. "System Image" is a dd backup of the entire system block device (/dev/block/bootdevice/by-name/system). 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: You only need to choose ONE of these options when making a backup!!
    • NOTE 2: If you are using a FAT32-formatted card, a "System Image" backup may fail (depending on your variant), due to the 4GB file limit on that format. For a successful System Image backup, internal storage or NTFS/exFAT-formatted external storage must be used (either SD card or USB-OTG)
5. How am I supposed to root?
  • Since the 10 has dm-verity enabled and forces encryption by default, root can only be achieved using the new "systemless" root methods. There are three currently working methods:
6. How do I backup stock recovery prior to flashing TWRP?
  • On the U11, you can "fastboot boot twrp-3.1.1-0-ocn.img" (from bootloader, not download mode) this will directly boot into TWRP without modifying your currently installed recovery. You can then backup stock recovery from within TWRP.
    You flash TWRP from download mode, but you boot TWRP from bootloader ('adb reboot bootloader').
  • Another common method is to extract the stock recovery.img from the OTA firmware.zip when it's received and use that to install the OTA.
7. 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).
  • 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!!
    • NOTE 2: It is possible to install an OTA without using stock recovery (i.e. installing it with TWRP). TWRP will not flash the firmware.zip included in an OTA file. Please see here for a detailed description of the process. (That post is for the HTC 10, for the U11 the proper zip filename would be 2PZCIMG.zip instead of 2PS6IMG.zip)
  • Reboot to system, install OTA.
8. 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 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)
9. 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 booted or 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.
10. After I restored my Data backup and boot back to Android, I'm entering the correct PIN/password, but it's telling me the password is wrong. What happened, and how do I fix it?
  • It appears that sometimes after restoring a backup of Data where security was enabled (such as a PIN or password lock), the device does not recognize the correct password. There are two ways to avoid this issue:
    • Disable security in Android before making a backup of data.
    • After restoring Data, while still in TWRP, use the TWRP File Manager to navigate to /data/system and delete all the locksettings.* files (such as locksettings.db, etc). When you reboot, the password will be gone.

11. Information about encrypted devices (by default all U11 devices are encrypted using FDE force-encrypt)
  • TWRP decryption on the U11 relies on the currently running ROM's own system files using 'vold_decrypt' to be able to decrypt your data partition.
  • If you intentionally or accidentally delete your system partition, and boot into TWRP without the needed system files, decryption will fail and you will be prompted to enter your password, which will continually fail due to the missing system files.
    When the TWRP console is shown during decryption, you will see a red text: "Missing files needed by vold decrypt: /system/bin/vold".
    If you encounter this situation, do not panic, do not format your data partition, you will most likely be able to decrypt again, once you have the needed setup back in place, without any data loss.
  • The easiest way to do this:
    1. Cancel the decrypt prompt
    2. Restore your last System or System_Image backup (no other partitions need to be restored!)
    3. Reboot to bootloader and then back to TWRP (since currently the direct reboot to recovery is broken due to the lack of kernel source code)
    Alternatively, in case you do not have a backup available, you can dirty flash whatever ROM you are running, or even fastboot flash a proper system.img, but considering that your system partition is not likely to have changed, since these days most things are run systemless, the restore is the easiest and fastest.

What's causing all the trouble regarding MTP/UMS here is HTC switching from sysfs to configfs for usb (it's weird because it's still labeled as "testing" in the latest Linux kernel....)

For those who like to have some info, you can check out the official documentation:
https://github.com/torvalds/linux/bl...t_configfs.txt
And for USB mass storage:
https://github.com/torvalds/linux/bl...t-mass-storage

Other functions can also be checked from files starting with configfs-usb-XXX here:

Well, for some reason the Downloads tab isn't working, so I haven't been able to upload the build yet. Hopefully that sorts itself out soon.

EDIT: John uploaded it, so let the flashing begin!

One thing to note is that you CAN fastboot boot TWRP on this device, so if you don't want to overwrite stock recovery, you don't have to

Can someone test this build for me? If it works, we'll be able to add official TWRP support for the U11 .

EDIT: Build doesn't boot. We're investigating why.

I'd get onto it for you but for some reason I can't log into HTCdev to unlock my bootloader to flash any recovery. It just says my user/pass doesn't work. Tried resetting password, tried making a new account, no luck! Anyone else having any issues? Keen to flash TWRP
