blackOPS please start from Section B.
I have no idea what to do when it says Revert your kernel to 3.52 i got to the recovery menu but i’m confused from there
Michael,
For the “Revert your kernel to xxx”, do this:
(1) Get into recovery menu as described.
(2) Choose “Configuration”.
(3) Toggle the “Game folder homebrew (currently at x.xx kernel)” to the version instructed.
Thanks everyone for your help.
I have a little problem. When I toggle the “game folder homebrew”, it leaves me no choice but to choose the 1.50 kernel.
I am in 3.71 m33.
