Hello XDA forums. First off I would like to apologize if a thread or something like this already exists, but I already spent way too much time trying to unroot my friend's phone since his vibration motor stopped working. Basically all that I am looking for, is a rom that can be flashed on an ATT HTC One M8 with OS version: 3.11.1700.5 and HBOOT: 3.19. I tried flashing many Sense roms already, but they all don't work. What I think is that the rom's base firmware's second section after the initial number has to match the phone's OS version. An example of this would be with the Skydragon rom, where it is based on the 4.04.1700.4 firmware. But it still works even though it has a higher version number. So what it all comes down to, is that I need to find a rom that supports the x.1700 firmware line so I can flash it restore to stock (mostly at least) Also instructions for returning to complete stock while S-ON would be helpful. Last the stock rom would be the most preffered, since then I can use the stock recovery and relock the bootloader.
