AT&T One M8 RUU Restore

[justein]

Hi, I am wondering if this procedure would throw a security warning in the bootloader...

Current status of bootloader: S-OFF, Unlocked, tampered.

1. Download RUU exe file.
2. Boot HTC One M8 into fastboot.
3. Revert CID
4. Remove tampered flag.
5. Change bootloader to locked from unlocked.
6. Return to S-ON with fastboot writesecureflag 3.
7. Run AT&T RUU exe file.

Will this put my bootloader back to locked, S-ON with no security warning?

I could be wrong but based on my past experiences once you unlock, and try to relock, the status will say "relocked" instead of locked.

You are s-off there is no need to do any of that, Just run the RUU . Is there a reason for going back to s-on?
If you need to send it in you can flash this modified hboot which removes the red text and makes it look s-on but you are still s-off

Can someone point to the RUU for AT&T on the One M8? I have been searching and searching....
