[Q] [Need help] problem of going back to stock
As I need to send back my One to HTC for repair so I have to go back to stock. I did go through the forum, the easiest way is to use RUU to restore. Unfortunately there is no suitable RUU for my region (622, Hong Kong). Only CWM Nandroid backup is available for download. So this is what I did to try to restore my phone.
- Lock the bootloader
- Restore the nandroid backup
- Use this command “fastboot oem writesecureflag 3” to S-On.
Everything is correctly running until I S-On the phone. After S-On, I got a “security warning” and the tampered flag came back. I still can boot the phone into OS but cannot boot into recovery anymore.
What have I done wrong in the process and how can I resolve it? Please help. Thanks!
