This topic may be beaten to death but I'm not able to dig up much info pertaining specifically to HTC One units from Wind Mobile.
First thing I did to the phone was unlocking the boot loader through HTCDEV. I then updated to 4.4.2 via OTA. At this point I tried to gain S-OFF with firewater but was unsuccessful but I can live with that for now. The last thing I did was install a custom recovery (TWRP 188.8.131.52) so I can root my device. Essentially my phone is stock aside from TWRP and root.
I received the Sense6 OTA update and know I can't update with a custom recovery installed. From my understanding, a stock recovery is required to install the OTA update. What do I need to do to remove TWRP and revert back to a stock recovery? Again, my HTC One is from Wind Mobile so I'm not sure if I can use any stock recovery img or are they carrier and/or firmware specific?
