So this is not the first time I'm getting into the bootloop, but this one is been killing me for about 1 month now. I have searched a lot, tried to go back to stock(again HTC rejects as i'm on a newer software version). The problem came in when I wanted to install Lollipop and I installed the TWRP new layout recovery and changed the file-system to install new CM12 ROM. That didn't work so I decided to go back to my old cwm 18.104.22.168 touch recovery which I had been using to flash the ROMs. I installed it successfully, reverted back to old layout and tried flashing CM 11 which worked flawlessly before. but this time its stuck at that cyanogenmod logo at startup. Can somebody help me with this?
