First check if the latest TWRP is installed.. secondly, Before installing data.. did u give full data wipe ... ? Coz before u install back up u give a wipe.. besides if u do a clean install via aroma it may ask u for installing via back up...check those..
Yes, i always do a full wipe before install a new rom and TWRP is also the latest one for oreo builds. I have done wipe befor install the newest version of Super Man Rom. Everything worked fine,until my battery was empty so phone turned off.I have charged it over night and turned it today in the morning,still got bootlooop,phone want to start boot but breaks at the halfe of the Superman Logo and reboots.
Have also tried to install the older 2.9. version,but still stuck in Bootanimation without rebooting the whole time. The blue light on top of the screen is also again on.
Should i try to do flash stock with odin or is my phone totally broken?
