I would like to install the AT&T OTA of 4.4.2 but have a custom recovery and am unable to upgrade. I am rooted with the stock 4.3 ROM and have the twrp recovery installed. I have S-ON. I've searched around trying to find a way to get this to work but can't seem to figure it out. I've tried looking around for an AT&T 4.3 stock recovery to try and flash it but can't seem to find one. The one from the Dev sticky page is not available for download. Can someone detail the steps I have to perform to get the 4.4.2 OTA from AT&T. Thanks in advance.
OK, problem fixed and 4.4.2 installed from OTA. I had relocked the bootloader on my phone so... start from scratch. Steps to resolve
1 - Unlock Bootloader
2 - Get S-Off on device (Makes everything easier). I used Firewater (http://firewater-soff.com
3 - Flash the AT&T 3.17.502.3 (4.3) RUU from here (http://www.htc1guru.com/dld/ruu_m7_u..._signed_2-exe/
). You may need a different one if not on AT&T
4 - Start phone, check for update. Let it download. Cake.
Now off to redo all the settings on my phone. Hope this helps someone else.
