First of all, I am new to Android development. I like to play around with stuff and a friend of mine who is a total noob asked if I could take a look at his HTC One SV. He said that the phone switched off during software update and now the phone is stuck in bootloop.
I spent 2 whole days reading up on what can be done and trying to fix it but right now I am fed up and would appreciate if anyone could help me in any way, especially a walktrough via PMs.
I tried to flash TWRP recovery via fastboot. It flashes, it goes on to the red warning message and goes back to bootloop after a minute. I think I tried every possible TWRP version. I cleared the cache before and after flashing. I flashed multiple times, I ereased cache multiple times with each image.
I am unable to go into recovery. What can I do about it? What am I doing wrong? What can I try? The guy that gave me the phone already made peace with the idea that it will never work again so I am willing to try anything. I would like to start from scratch as I do not know if anyone played with it before me.
