I have a AT&T HTC One from launch day. I recently flashed the AT&T stock ROM for 4.4.2 over an old 4.2 Google Play Edition ROM for my phone. I used ADB Sideload in TWRP 2.5 to do so. I also rooted. After flashing, I was fine for about a day, but then two issues occurred.
1) I can no longer send texts. I receive them fine and the phone works otherwise for calls, Wi-Fi, data, etc. but nobody I've texted is receiving texts. I've tried using a third-party client and the built in one.
2) If I reboot the phone, the phone will boot up normally, work for about a minute or two, then reboot again. This cycle repeats until I flash again. Clearing the caches does not help. I'm still able to access everything until it reboots and getting into the Settings menu seems to prevent this issue from occurring, but I have no idea why this is happening.
I know I can always flash another ROM and those seem to work fine, but I'd really like to stick with stock or a similar-stock experience where I can root. Anyone that can recommend a solution or a ROM that's close to stock would be greatly appreciated! Thank you!
