Hey My OneHack Family i’m trying to Root my
Amazon Fire 7 2019 9th gen FireOs 6.3.1.2 to LineageOs 14.1
missing one file called mtk-su_r21 anyone have it thanks
Hello, mtk-su_r21 is one of the rarest version mtk-su, so why don’t you try r22 or r23, they support Amazon Fire 7 on both versions.
So here it is a link of
mtk-su_r22/r23
Have a great day
