Here are the steps leading up to this situation:
- Using Fastboot, flash the stock recovery. Previously, I had TWRP 22.214.171.124 installed, but I went back to stock recovery (from this thread) so that the OTA would work.
- Apply the update. This causes the phone to reboot and go through the update procedure. I wasnít paying attention to the progress bar, so I donít know if it finished or not.
- When I next look at the phone, itís showing the exclamation mark symbol indicating that the phone has booted into the stock recovery. Instead of entering the recovery, I force-reboot the phone by holding down the power button.
- The phone reboots. Now I see the decryption key entry screen, which appears to have been updated in the OTAóthe visual style is different from before. I enter my 6-digit PIN, the same one I was using before the OTA to decrypt the phone.
- I press the Decrypt button, but after a second the prompt text changes to ďThe password you entered is incorrect.Ē Strangely, the number of remaining attempts does not decrement, but remains at 30. I am unable to boot my phone.
I can still reboot the phone to the bootloader menu, and I can enter Fastboot or recovery. However, the recovery is still unable to mount the data partition.
For some reason, I can take screenshots from the decryption prompt screen using Power + Volume Down.
Please help me fix this! I would very much prefer not to lose all my encrypted data, if at all possible.
