Flash1 problems again.

My Japanese TA-79 PSP have a annoying problem. The letters showed in the box of the XMB text entry are corrupted or garbled... an example: instead "j k l J K L 5" it shows "jklJKL5" , strange things or nothing ! It occurs randomically.

Some times PSP shows "An internal error has ocurred" then BSOD and if i press Circle it gimves me an irrecoverable brick and i should restore my NAND dump. If i dont press circle but reset and enter in Recovery Menu and format flash1 it backs to the normal but only for a short period of time or worse : It give me internal error or BSOD at first settings screen.

Another synthons like of corrupted flash1 like mad battery metter, freezing after exit homebrew/UMD games and etc... occurs.

I tried dowgrade to 1.50 and reinstall everything, use flash1 formatter, install OFW then dowgrade again but nothing gives me an deffinitive sollution. When i dump my NAND with PAndora no bad blocks are showed... so i cant understand what are happening...

Someone have any ideas ?

Thanks for the attention.

try deleting everything in flash 1 manually.

If all else fails try chilly willy's key cleaner, it sounds like an idstorage problem.
