Same i have the problem yesterday ago i test another time to root my A6OOFN android 9 and have security problem,cant acces to samsung account,cant use fingerprint or faceunlock...Can u singnin to Samsung account? If I root with magisk I cant use Samsung account Android others maps like authy 2FA. If I flash shock ROM without root everything works normal. I tried to flash stock image, then sing in to Samsung account and then flash TWRP, rmm bypass, dm_verity and disable encriptation Force, magisk.zip. But twrp cant uncrypt data partition. Do u know how to root and sign in to Samsung account?
