You can downgrade it to any of CFW's (M33's), so the newest is 5.03 M33, but I recommend you 5.00 M33-6 - super CFW ;)
i think the best is 3.52.m33-4
how to activite the gprs to my m33 cherrymobile
Google the keywords "M33-1 for PSP" and you will get sites from which you can dl the update.
you cant because M33-6 gets corrupted and M33-3 gives an error code
Yes. Any firmeware that enda in GEN or M33 or anything like that can play ISOS and CSOS.
You have to have 5.50 OFW to run iso's, 3.71 and 5.00 m33 don't run iso's

The M33 highway in Michigan has been around since 1919 and is still in great function today. The highway stretches a total of 121.858 miles across the state.
Only if you have m33 (custom firmware) for it.
Just run a sowny ofw update. This should work. If not, check google. its your best bet. i had the same problem myself and am still struggling to fix it.
There's no way to do it.
