I'm not new to HTC and it's procedures but I have a problem this time I bought a used A9, it's s-off, bootloader says unlocked but download mode says locked, I flashed twrp recovery through fastboot and I boot into recovery without problems, but when I reboot the phone it goes into unending bootloop, so I flashed RUU again and it was fine, I did the fastboot method all over again because I need to root my phone to get the most out of it, but yet I got stock bootloop again, is there something I'm missing here? Please people come to my rescue...
