so i had a custom firmware on my psp for a while and i wanted to go back to official sony updates so i got it back to 1.50 but it wont update from there. its either says the update data is not applicable or some other message. Any Ideas?
Ok zulo doesn't get it, but why would you want to go back to official anyway? Everything's worse :/
But it's due to the fact that newer firmwares can only install if you already have a certain firmware. In other words, you have to install in increments, though i can't remember which path you have to take any more - It's been a couple of years.
Try installing 2.71, then 3.50, and so on, those two seem to pop into my head, though i might be wrong :P
