[Sprint HTC One (M7)] kcdem13:
Putting exit helped get me to the lock command. My phone still has the white HTC on a black screen. I am not touching it for at least 15 minutes, but I'm not sure it worked. Here is the code.

Did it work? I do have a stock-rooted ROM flashed through OTG recovery. Should I use my OTG to flash Sprint_HTC_One_1.31.651.2_Stock

Or will it still keep me in that 30 second boot loop?

After 20 minutes I boot back into bootloader and everything is gone again, including my recovery. I will go back to step 1 and try again.

I flashed the Sprint stock ROM and it loaded with all of the apps showing. It looked like it might be fixed but then it rebooted again. I noticed when I flashed in recovery it said checking MD5... no MD5 file found. I remember reading early in this thread someone mentioned that MD5 files missing might be the culprit for the reboot. Could this be the case? Should I try the adb shell effort again? I feel like I'm getting close. Stock rom is restored but it keeps booting!

I'm just not having any luck. Here is my latest attempt.
