and so we've heard that we can downgrade any custom firmware to 1.50
using the "recovery folder 1.50"

but recently i used universal unbricker v3 for my friend to go straigth to cfw 3.71m33-2 and even updated with 1.50 kernel add on

and so i tried using the recovery folder and it fails to run 2 files (which i cant rmb) and then go on to brick the poor psp (which has to be unbricked again)

and so my question: how do we downgrade 3.71m33 back to 1.50?

if u can get into the m33 recovery menu, toggle usb, delete ALL files off memory stick(not folders only files), then put the recovery ebbot file in its right place, run the ebbot and c if it works, if it dont then u need a pandora battery otherwise ur stuck with the brick
