I posted this problem on another forum and haven't received any help yet, but I need to get my phone to working condition, so posting it here as well.
I have an HTC One M9 Dev Edition. It is rooted, bootloader unlocked (since dev ed) and s-on. I had 2.8.617.4. I have been getting notifications to update it to 2.11.xxx.x, but since I was rooted, I couldn't update. So I thought of reverting back to stock to get the OTA. I booted to recovery (TWRP 2.8.7.0), tried restoring to the nandroid system that I had a backup of (1.32.617.30). That failed, with system is read only error or similar error message. So I followed Extra Section from this guide - http://forum.xda-developers.com/one-...guide-t3087354.
After finishing the steps, my phone is now stuck on the htc logo. I'm not sure what is wrong. I can boot into recovery. One thing I notice is when I boot to download mode, I still see the OS as 2.8.617.4. I tried flashing system again, I still see the same thing and the same problem. Are you not allowed to flash an older system than what you're currently on?
I didn't flash anything else, I read something about flashing compatible firmware as well. I thought that the firmware will be included in the system image. Is that the problem? Or can I flash the image for 2.8.617.4 and get back the phone to working condition? Really need your help. Thanks.
