Hello guys, I want to downgrade to android 6.0.1, but i can’t find the right(correct) firmware. I have tried a lot of firmwares, but in the end, something won’t work, vibration won’t work, or phone is working too slowly... my csc is: G935FAUT2DRB1. My pda is: G935FXXU2DRB6. In the sammobile webpage I have found android 7 with csc and pda, but android 6 I can’t find, could someone tell me how can i find the firmware? Thank u.
