My phone right now is unlocked and with s-off. I was thinking I could relock the bootloader and run RUU to go back to complete stock (with S-OFF). My question is can I install the tmo update with S-OFF? Has anyone done this before? Or do I have to go back to S-ON in order to install the update?

I know that rumrunner does not work with HBOOT 1.56.

Any help would greatly be appreciated, thank you.

don't think S-OFF or unlocked matters, just stock rom and recovery required

My phone is unlocked/S-OFF. On the previous OTA updates, all I had to do was reflash the stock recovery and the updates proceeded normally, installed just fine. On this new OTA update to 4.4.2, however, that didn't work. I tried relocking the bootloader, flashed the stock recovery... nothing worked (it would get the red slash during the recovery part of the OTA update). Evidently, T-Mobile/HTC are now much more picky about modified devices.

So, to get the OTA to work, I had to run the last RUU from T-Mobile. That, of course, wiped my phone clean, but installed a locked fresh 4.3.1 ROM (still S-OFF). Then the OTA update ran perfectly, resulting in the 4.4.2 OS installed. Then I unlocked it, flashed TWRP recovery and rooted it. It's working beautifully.

Thank you for the information.
