Chears,

seems 'fastboot boot' not always working...

just send you the link in case you are interested to write up an answer
https://android.stackexchange.com/questions/233126/htc-u12-flashing-twrp-stuck-booting

Greetings
Why aren't you asking here?

You have to be in BOOTLOADER mode to use fastboot boot, not DOWNLOAD mode. It sounds like you're in the wrong mode when you're running the command. Please confirm what mode you're in and try again.

i don't own this device. i already suggested to ask here. nevertheless if the output is ...
Code:
fastboot boot twrp.img
Sending 'boot.img' (32424 KB)                      OKAY [  2.006s]
Booting

You can doubt all you want, but that's the #1 symptom of being in the wrong mode. The easiest way to confirm which mode the user is in is using the command
Code:
fastboot getvar boot-mode
Please report back the output of that command. If the output is "download", then you owe me an apology.

No post since 6 month... hmmm.
Can anybody tell a success restore from any version TWRP backup?
Tried it on 3 HTC U12+ with all system versions and the fitting TWRP versions, permanent and temporary. All end up in a bootloop.
I read all now in here but a restore never was mentioned. I need help please!

Hello, I have read your problem and some posts the other days.. Usually I sometimes make nandroid but I hardly ever restore them. That's why I didn't make this mention. But Now i was curious about it so i have made a nandroid and i have restored only the system.. yeah i have finished in a bootloop too , I was forced to reflash my rom. I have using the last version of twrp 3.5.0_9-0

So if i understand you was able to fix the problem with flashing the fix_rootfs_label_U12 + _CPTB.zip file of @Captain_Throwback after having restored the backup and that it?

I have a similar problem and get-var gives : boot-mode: download

I can boot TWRP when I am on 2.55.401.1 and no chances when I update the system to 2.55.401.3
always stuck at booting...
Tried different PC's, drivers, cables.

excuses - it worked only once with patched 2.55.401.1 with old magisk. Now I can't boot TWRP on any of my 2 u12's. Always stuck at 'booting...'

ok. TWRP starts from bootloader not download mode in my case.

    All flashing is done at your own risk!
    While nothing from this thread should break your device,
    don't come back here blaming anyone if it does!

    Hello Guys and Girls,

    the title is obvious: Here is a twrp build for the HTC U12+. I spent quite a bit of time together with the dear @Captain_Throwback to get everything working.
    At this place a huge thanks to @Captain_Throwback for helping me, even though not having the device at his hands!

    Instructions:

    With A/B devices the command
    Code:
    fastboot flash recovery recovery.img
    is not possible, because these devices generally don´t have a recovery partition any longer. The recovery sits now in the ramdisk of the boot.img.

    So how do we get TWRP on it?

    The first option is to just boot TWRP temporarily with the command
    Code:
    fastboot boot twrp.img
    . This will just boot up TWRP, not actually flash it onto your device. After rebooting the phone, TWRP will be gone. This is a great option for those, who just like to flash their phone one time, don´t want to modify the boot.img and don´t need a permanently installed TWRP.

    The second option is to use the twrp flashable installer zip to install TWRP permanently to your ramdisk from the booted TWRP or magisk manager! Installing from Magisk Manager was made possible by @osm0sis!

    So you see there are generally 2 steps needed on A/B devices now.
    First booting TWRP. Second flashing the installer zip.

    But and now comes HTC into play. When permanently flashing TWRP zip touchscreen gets disabled, because HTC added a nasty little check into the touchscreen driver. If it detects that the phone is in recovery mode it disables the touchscreen.

    Luckily we found 2 ways around that!
    First way is to have a custom kernel, that has this check patched out!

    Second option is to use a zip we provide here, that also patches your kernel, to avoid tripping this check. The downside of flashing this zip is that all commands like
    HTML:
    adb reboot recovery
    , hitting reboot to recovery in magisk manager and finally reboot to recovery in TWRP are not working and only boot to the OS!




    How to temporary boot TWRP:

    1. You need a working fastboot and adb environment! Your device´s bootloader must be unlocked!
    2. Download the twrp.img provided in this thread and copy it to your fastboot folder (pay attention that firmware version matches)
    3. Open a command prompt in your fastboot folder!
    3.a While your phone is booted to the OS and USB debugging is enabled, type:
    Code:
    adb reboot bootloader
    4. You need to fastboot boot twrp currently
    Code:
     fastboot boot <filename of the twrp.img>
    example:
    Code:
    fastboot boot twrp-3.2.3-2-ime.img
    5. Wait for twrp to be booted
    6. You´re now in TWRP
    7. Please note that you need to fastboot boot the TWRP every single time you need it. After a reboot it will be gone!
    8. Important:
    Please note that
    Code:
    fastboot boot twrp.img
    (like done in step 4) will also break OTA functionality. More about this in the FAQ.


    How to permanently flash TWRP via the .zip installer

    1. Make sure you have a working fastboot and adb environment! Your device´s bootloader must be unlocked!

    2. Download the flashable TWRP installer zip provided in this thread!
    2a. If you´re on a stock kernel that has no touchscreen fix for recovery included please also download the touchscreen_hexpatcher.zip

    3. Flash the TWRP-Installer.Zip from the booted TWRP or Magisk Manager on your phone (hit the + while in modules section)
    3a. Important: Directly afterwards flash the magisk zip from TWRP or Magisk Manager
    If you don´t flash it you will only be able to reboot to TWRP, regardless of the option you choose

    4.Only needed when on stock kernel without touchscreen fix:
    also flash the touchscreen_hexpatcher.zip from TWRP or Magisk Manager
    Be aware that flashing touchscreen_hexpatcher.zip will make touch work when using stock kernel but render all recovery related commands unusable.
    This includes
    Code:
    adb reboot recovery
    , reboot to recovery from magisk manager and reboot to recovery from inside TWRP.
    To get into TWRP you first have to reboot to bootloader and from there on to TWRP/Recovery!


    5. Reboot
    6. Congratulations: you can now reboot into your permanently flashed TWRP :)

    How to permanently flash TWRP via the TWRP.img file inside TWRP

    1. Make sure you have a working fastboot and adb environment! Your device´s bootloader must be unlocked!

    2. Download the twrp.img file from the offical twrp site
    2a. If you´re on a stock kernel that has no touchscreen fix for recovery included please also download the touchscreen_hexpatcher.zip

    3. Boot to TWRP. Navigate to Advanced -> Install Recovery Ramdisk -> Choose the twrp.img downloaded earlier. Wait for the flash to be completed successfully and do either 3a or 3b.

    3a. If you want to be rooted flash the magisk.zip
    3b. If you don´t want to be rooted navigate to Advanced -> Fix Recovery Bootloop to be able to boot into system

    4.Only needed when on stock kernel without touchscreen fix:
    also flash the touchscreen_hexpatcher.zip from TWRP or Magisk Manager
    Be aware that flashing touchscreen_hexpatcher.zip will make touch work when using stock kernel but render all recovery related commands unusable.
    This includes
    Code:
    adb reboot recovery
    , reboot to recovery from magisk manager and reboot to recovery from inside TWRP.
    To get into TWRP you first have to reboot to bootloader and from there on to TWRP/Recovery!


    5. Reboot
    6. Congratulations: you can now reboot into your permanently flashed TWRP :)



    Few tips and tricks:

    1. You need to mount ext_sd card before you can access it in the file manager
    2. Go to mount and click on mount usb storage to access the ext sdcard when connected via USB :)
    3. Don´t forget you can connect an usb device via usb-otg to backup/flash stuff from/to an usb storage device

    • fastboot booting TWRP mounts the system RW and breaks ability to take an OTA.
      Please take a look at FAQ, found in the 2nd post here. It contains more information

    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.

    We need your help!

    Tips on how to build TWRP for the U12+ yourself:

    To build TWRP you need to use this branch as your device tree:
    https://github.com/freak07/android_device_htc_ime

    Additionally you these commits from gerrit to your twrp tree!
    https://gerrit.omnirom.org/#/c/android_bootable_recovery/+/31760/
    https://gerrit.omnirom.org/#/c/android_bootable_recovery/+/31207/
    https://gerrit.omnirom.org/#/c/android_bootable_recovery/+/31021/

    Depending on the base you're building for, you may need to comment/uncomment the PLATFORM_SECURITY_PATCH flag for your respective build if you want to fastboot boot the twrp.img. If the patch level of the image doesn't match the patch level of the current system, decryption will not function when fastboot booting the image. If installed via zip, the patch level doesn't matter, as it is automatically updated from system using @topjohnwu & @nkk71's resetprop.

    Attention Ladies and Gentleman :)

    with the help of the relentless @Captain_Throwback we finally resolved all the major issues on TWRP for the HTC U12+!

    This release includes a flashable twrp installer zip that will flash TWRP permanently on your device. That means you don´t have to
    Code:
    fastboot boot twrp.img
    every single time!
    There is one downside when using that flashable zip though. HTC implemented a nasty check in the touchscreen driver, which checks for recovery mode. When it detects recovery mode touchscreen gets disabled. This doesn´t relate to just
    Code:
    fastboot boot twrp.img
    We managed to bypass this too:
    you have two options:
    Option 1: Flash a custom kernel like Kirisakura or Cleanslate which will be patched to bypass this
    Option 2: If you´re on stock kernel, flash the Imagine_touchscreen_hexpatcher-CPTB.zip made by @Captain_Throwback
    This zip will make touchscreen work in the permanently flashed recovery! But be advised that this will break all recovery related commands/actions (like
    Code:
    adb reboot recovery
    , reboot to recovery via apps such as magisk manager and reboot to recovery in TWRP)


    But it gets better again! Way better!
    thanks to the work of @osm0sis it´s possible we flash this installer zip directly in the magisk manager app. Which means, if you´re rooted you don´t need a pc to permanently flash TWRP to your U12+! However it´s advised to have one nearby especially if it´s the first time doing this!
    This is really handy!!

    Important:
    Always flash magisk zip directly after flashing the TWRP installer zip! if you don´t do this you will only be able to reboot to twrp, no matter what!

    Attention Ladies and Gentleman,

    here is the last update before I go on vacation. I think with the update we should have everything covered.

    thanks to extensive testing done by @Electronic Punk a bug was discovered and squashed that prevented /system from being able to be mounted as R/W.
    At this place thanks to @Captain_Throwback again :)

    The permanent twrp installer zip now displays a message after flashing, asking you to reflash magisk again.

    There were more behind the scenes updates :)



    Instructions:

    How to temporary boot TWRP:

    1. You need a working fastboot and adb environment
    2. Download the twrp.img provided in this thread and copy it to your fastboot folder (pay attention that firmware version matches)
    3. Open a command prompt in your fastboot folder!
    3.a While your phone is booted to the OS and USB debugging is enabled, type:
    Code:
    adb reboot bootloader
    4. You need to fastboot boot twrp
    Code:
     fastboot boot <filename of the twrp.img>
    example:
    Code:
    fastboot boot TWRP_3.2.2.0_Imagine.img
    5. Wait for twrp to be booted
    6. You´re now in TWRP
    7. Please note that you need to fastboot boot the TWRP every single time you need it. After a reboot it will be gone!


    How to permanently flash TWRP

    1. Download the flashable TWRP installer zip provided in this thread!
    1a. If you´re on a stock kernel that has no touchscreen fix for recovery included please also download the touchscreen_hexpatcher.zip

    2. Flash the TWRP-Installer.Zip from the booted TWRP or Magisk Manager on your phone (hit the + while in modules section)
    3. Important: Directly afterwards flash the magisk zip from TWRP or Magisk Manager
    If you don´t flash it you will only be able to reboot to TWRP, regardless of the option you choose

    4.Only needed when on stock kernel without touchscreen fix:
    also flash the touchscreen_hexpatcher.zip from TWRP or Magisk Manager
    Be aware that flashing touchscreen_hexpatcher.zip will make touch work when using stock kernel but render all recovery related commands unusable.
    This includes
    Code:
    adb reboot recovery
    , reboot to recovery from magisk manager and reboot to recovery from inside TWRP.
    To get into TWRP you first have to reboot to bootloader and from there on to TWRP/Recovery!


    5. Reboot
    6. Congratulations: you can now reboot into your permanently flashed TWRP :)
    7. Please note that MTP will not work when you use the permanently flashed recovery!

    Attention Ladies and Gentleman,


    here is the long awaited TWRP release with working decryption of your data partition. This is @Captain_Throwback ’s work I just compiled the builds with his fixes for decryption as mentioned in one of the last posts.
    That means access to /storage and flashing magsik to obatin root is now possible.

    Before flashing magisk, mount system in the mount options.

    The only thing you currently have to keep in mind is, this twrp is not yet flashable. Which means you need a pc to boot it! We´re working on the zip to permanently flash TWRP. So tinker wisely with your phone.

    Important!!!
    For decryption to work there is a seperate build needed for both 1.15 firmware and 1.21. That is due to the security patch state being different. If you use the wrong one you can´t access data when booted to OS again.


    Downloads:


    Choose the TWRP that matches your current firmware and OS!

    1.15:
    https://www.androidfilehost.com/?fid=5862345805528059739


    1.21
    https://www.androidfilehost.com/?fid=5862345805528059740

    Disclaimer
    When rebooting from recovery, you´ll see a message "NO OS installed", swype it away and reboot it´s fine. It´s cosmetic and will be taken care of in one of the next releases probably.

    please, when flashing magisk, mount system in mount option beforehand. This issue will be dealt with later :cowboy:

    If you have any issues please state your current firmware, the version of twrp you flashed, as many details as possible and provide a recovery.log.
