[Galaxy S6 Edge Q&A, Help & Troubleshooting] Acidics:
Whoever can respond with an answer will be a godsend. S**t hit the fan so hard so quick. to give a rundown of whats happening. just recently returned from traveling abroad. during that time something happened. cant hardly remember. whatever happened. i can recall i knew i needed a rooted phone to fix it. (im pretty tech literate) so ive tried ping pong root. im running 6.0.1 marshmellow on my s6 edge G925A. ive learned a root is not possible on this version. but for 5.1.1 it is. however id prefer to stick to 6.0.1 so i kept digging. now that was over a course of 3 weeks with no access to a computer across seas. so i decided to take the time to learn to use odin to flash a rom since from what i read ive found a rooted 6.0.1 att rom. (I could care less about knox. past warranty etc.) its more important for me to have a functioning phone that i can have control over. but the issue was ads popping up system wide. random acts of terror on my phone. phone would randomly install apks/files. or force close every app suddenly. uninstall apps. NOTE: i havent side loaded any apks other then ping pong root from the xda thread. nor any other file that would seem to have possibly been tainted that i downloaded. whatever happened. thats the past. right now its gotten worse. ive decided to try to sit down and figure out odin to fix it. now yes i could do a factory reset and get on with my life. but i really want a rooted phone. and since ive got a backup and im already in the middle of it.. why not just root it. but that tar file is for 5.1.1. not 6.0.1. so im curious if thats the case im gonna just install a custom rom which would be way more open and user controlled then freaking AT&T's so called open interface of android. so im here to ask. is it possible to go from 6.0.1 stock marshmallow android and flash the Extreme Syndicate v3.1 Custom ROM for my phone for version 5.1.1 Lollipop android? if so can you provide a somewhat step by step if needed. ive read you would have to flash stock rooted 5.1.1 then flash the custom ROM. if thats true please point it out. I need this phone to be alive and well for my business while allowing me to make it mine. not a brick so im open to any advice to get this task done. xdadevelopers are a life saver to say the least. but right now im needing a big life save now. so anything helpful is needed ASAP! THANK YOU for reading and helping a needy soul out! heres a list of specs and short rundown so you dont have to sort through this life story lmao!
