yo this is my first post but i wanted to ask, i got a friend to help me convert my fat psp into a m33-3 software since hes a computer wizz, and this was a while ago, so my psp is currently a 3.52 m33-3.
i was wondering if i can actually convert it back into the original firmware since i am having problems and i really want it back (u guys must be thinkin im an idiot)
The problems are that the DADADADA problem keeps coming up (dark alex) because the firmware was by him...
please help cheers
Yes you can turn it back to the official firmware, just upgrade like you would a normal PSP. If your getting errors just try another custom firmware, this is my recommendation because you can use homebrew.
No.
You wont be able to update from a custom firmware to an official.
Thats what the DADADADADA error code means.
Use this guide to downgrade to 1.50 and then you can upgrade to any official firmware you like
