I just today updated my unlocked, rooted HTC One M7 as usual, by
- flashing the stock recovery
- rebooting and downloading / installing the system update
The update went over without any problems, but after the update completed, it did not complete the boot process any more. It's stuck at the boot-logo of htc, after displaying the carriers logo. Forcing it to shut down and go in to the bootloader works fine, aswell as opening the recovery (both the stock one, and the custom one [TWRP]). However, no matter how many times I try to reboot, no success.
Normally in this situation, I would obviously just restore a previously made Nandroid backup, but since I am asking this question, well, you guessed it.. I felt too comfortable with the process and skipped the step of creating one.
I am really, really hoping that there is a way to fix this issue without having to lose my data.
Some additional information;
- CID: VODAP110
- OS before update: 18.104.22.168 (Dito for stock recovery)
- OS after update: 22.214.171.124
- Unlocked and S-OFF
- H-BOOT: 1.61.0000
- RADIO: 4T.35.3218.16
(It is an m7_ul variant, so nothing un-standard there)
EDIT: Due to the necessity of me being able to use my phone I gave up and chose the easy way out -> recovery, through a nandroid backup a few months back. However, if someone still finds an answer to this, I am very happy to accept it, for future viewers.
