Corrupt data all of a sudden

[mikesta99]

Hey guys, ever since I updated to 4.01m33, a lot of my songs go corrupt. Then all of the other songs will just lag around the middle and just freeze. I tryed adding the music on again and same thing happened. Also, when I add updates to my mem stick they usually go corrupt.


My updating proccess (might help)

I backed up my psp

Added the update

Updated the psp

added my last backup in my mem stick

and it started from there


EDIT: 1 More question. I have never downgraded before because whenever I brick, my MMS just puts my back at 8.1m33xx. I want to down grade and get back to 3.90m33xx, I just like it better. So do I have to make a new typy of MMS

BUMP: I need answers lol, im leaving for the weekend and I have about 7 hours of driving. I need my tunes!

For making the MMS take you to 3.90 you will have to create it for 3.90. Use the link in kevs tut for his pandoras pack as the mem stick maker takes you to 3.90m33.

Hopw that helps a little. And with your tunes are they in wma? Becuse if you had them wma and you had the ebnable wma playback before updating the update may have disabled it???

ok thanks for that, but how do I actually downgrade I know its newb but ive never done it before

Exactly the same as upbricking. Put the MMS in then the pandoras battery and it should auto boot (If not then the MMS is not magic or it needs charged )
