Okay did you try running RUU of nougat?Ok. I was able to get back to 3.39.531.41 by getting the 0PJAIMG from AndroidFileHost.
After that, I went to Recovery Mode (using pwr + vol up after seeing the red triangle), chose Apply Update from SDCard, selected the OTA file for 4.27.531.6. This time It didn't give any error, at the end it appeared to get stuck for a long time at the line Script Succeeded Result was [/preload]. After about an hour, I turned off the phone and on again, now it is stuck at HTC logo splash screen.
Questions here:
1. Was the phone really stuck at the "script succeeded" line?
2. Didn't I wait long enough?
3. What should I have done at that time when it stopped at that "script succeeded" line?
4. What should I do at this splash screen? It has been like that for the last 10 minutes
Thanks
If not run it.
Try running it 2 3 times.
If you get signature error than go for RUU of marshmallow i will post it in a while
Well how you manage to get back recovery?
About questions well you didn't did any wrong these things happen sometime.
