[Unofficial] HTC U11+ TWRP Recovery

[sabpprook]

It have been about 2 years, I finally get a U11 plus to make TWRP device tree with working decrypt function.
Source: https://github.com/sabpprook/android_device_htc_ocm

Please download latest TWRP build in following link.

[Android 8.0]
twrp-3.3.1-0-ocm_171001.img
twrp-3.3.1-0-ocm_171201.img
twrp-3.3.1-0-ocm_180601.img
twrp-3.3.1-0-ocm_180901.img
twrp-3.3.1-0-ocm_181001.img
twrp-3.3.1-0-ocm_181101.img

[Android 9.0]


PS. watch out the last 6 digits at the filename, it must equal to your system's android patch level. e.g. 2017-12-01 (Dec, 2017) = 171201, otherwise TWRP will not decrypt data partition.

PS2. U11+ already get Android Pie update, but this update will break data decrypt function in TWRP recovery.

@nkk71, thanks all the works you've done for us.

Awesome!!

 

[sephstyler]

yay. now to get more dev support behind this!

 

[tbalden]

excellent! Please, try to put up a github repo for it, if not already
Hopefully it works fine.
If HTC rolls out kernel sources, I might try some blind development, as I don't have the device, but wanna support it.

Should you need to unlock the official htcdev before they can put?

Yes, unlock then you can boot it.

Thanks for this! Going to try and get it up and running later today - Need to unlock the BL first.

Thanks for this however it doesn't seem to work for me. I've unlocked the bootloader, rebooted into bootloader mode via adb (adb reboot bootloader), tried to boot the twrp image (fastboot boot twrp-3.1.1-2_unofficial-ocm_2.img) and all I get is a black screen even though the commands seem to work at first:

fastboot boot twrp-3.1.1-2_unofficial-ocm_2.img
downloading 'boot.img'...
OKAY [ 0.894s]
booting...
OKAY [ 10.112s]
finished. total time: 11.006s

Any idea what's going on?

Did you flash the custom recovery ..?

P.S. Nothing of linked below worked out?

Yet sent from my amazing silver U11

I didn't flash since I wanted to test it out before using the fastboot boot command recommended in the original post. However this does not seem to work. I wanted to get twrp running so I could use magisk for root

 

[aurelienlux]

Went ahead and flashed it anyway and I'm happy to report that it worked and did not brick my device. So I still don't know why it won't let me fastboot boot but at least TWRP is now installed.

Be aware that you're now lacking the ability to ota update if you cannot get ahold of a stock recovery.
That's why booting only and making a backup of stock recovery boot and full system partition, is highly recommended.

I bought the right version of the stock rom I'm running from en.pars-hamrah.com. It's a slightly sketchy looking site and it cost me 9$ but it should allow me to go back to stock easily

I'll share it here if people are interested. It's version 1.05.400.13 which is the latest version for the Hong Kong version

OK, that's very professional. :good:

Just others be aware that you should make sure you have a way backwards.

That would be fantastic and very good of you if you could share it. Many thanks!

@nkk71 Any idea of decryption problem?
Seems "/firmware" not symlink and "/vendor/bin/qseecom" sepolicy not set correctly

Looks like you're building in android 7.1 for Oreo decrypt, won't work without the needed sepolicy changes and plat/non_plat contexts, please check the current gerrit updates for the standard HTC U11:
TWRP vold_decrypt patch: https://gerrit.omnirom.org/c/26652/

EDIT2: U11 Oreo decrypt device tree changes needed for a 7.1 build: https://gerrit.twrp.me/c/2756/

If you end up with decryption successful, but it doesn't actually mount /data, then you may even need an updated kernel https://gerrit.twrp.me/c/2761/
which is what we needed. EDIT: Obviously that's a U11 kernel update not a U11+ one, so don't try to use that kernel

Some things will still get changed. I also recommend you build in real DEBUG mode, the straces have much more info than a log or dmesg. by using TW_CRYPTO_SYSTEM_VOLD_DEBUG := true

There you go: https://drive.google.com/open?id=1nkzK_wbSgC6HSlOsNqOc79f94p7v_3wz
That's version 1.05.400.13. I managed to decrypt it successfully using the latest RUU Decryption Tool on Windows. I have a decrypted boot.img and system.img but I haven't yet uploaded those to my drive.
