I come from a soft brick and after some issues I got my m7_ul back to stock, which is great as it is alive again Now I want to flash a decent ROM, I have thought about ViperOne. However my TWRP 22.214.171.124 seems corrupted, I can't even enter it and I have had a couple of scary moments as the phone won't boot to system. Finally pressing the power button for like 30 seconds did the job and it booted to system. Stock ROM sucks but it is better than a brick haha.
My phone is international m7_ul, my HBOOT is 1.44 and I have Tampered and Unlocked labels, not sure what should I do exactly. Just want the basic strategy to get my custom ROM running and later on I will add a soundmod but that should be easier.
