I think i have formated flash1 but not sure, i will test this again. psp also freezing when exiting recovery mode.Īlso tested with no memory stick at all and original umd. Psp brought to me by a friend with this problem, psp was at 3.71m33, same state, freezing when runing a game, from memory stick or from original UMD.įirst thing i did was upgrading to 5m33. if all of the above doesn't work, then you could try and update to v5.00m33-4. then exit the vsh menu and try again.Īlso im not sure if your aware, but there is a new version of v5.00m33 available. scroll down to "umd iso mode" and press left or right on your d pad until it reads either "m33 driver" or "sony NP9660". Have you enabled the "use no umd" option? you can do this by pressing "select" in the xmb, and the vsh menu will appear.

but if it reads "unknown", then you have a fake.ĭid you format your mem card after you install v5.00m33? if not, copy all your game saves and anything you wish to keep and format the mem card using the psp's format utility (found in the "System Settings" icon). if it reads "supported" next to it, then you have an original mem card. a small list will appear with your mem cards details. To check to see if you have a fake mem card, (with the mem card in the psp) highlight the "memory card" icon in the "game" icon on the psp's xmb (main screen) and press triangle.

the psp will then reset itself and you will need to re-enter the time, date etc.

then scroll down to "format flash1 folder" and press enter (don't panic, this will not brick your psp). enter recovery menu, scroll down to advance and press enter.
