[One (M7) Q&A, Help & Troubleshooting] jerin1365:
I tried flashing the RUU. The same thing happened. Flashed successfully, but boots into stock recovery showing bunch of errors.

Here is the code:

These are the errors that I get in the stock recovery:

E:missing bitmap oem_unlock_bg

E:missing bitmap oem_unlock_bg_yes

E:failed to mount /data (Invalid argument). . try emmc mount

The only option I can really use in stock recovery is wipe cache partition. All others result in more mounting errors or reboot.
