umd games works but i got many iso. but the psp can't load it
and also the programmes can't run because of 3.90 fireware
what can i do ? got psp which no of the loaders works on it ???
You should have no problem with iso games. my works just fine and i have 3.90 the only difference is that it adds more network acess and skype so you might have to down grade your psp to get them to work again.

your psp version needs to modify to run iso format of psp games.. that version was made to run game through UMD only. theres way to make your PSP run iso games
>>>> update your OFW (official firmware) to 6.20 version
>>>>www.psp-hacks.com using that link you can find there on how to patch the pro-b4 to make your PSP run ISO like standard PSP 2000. enjoy and learn!!!!! good luck note: when updating make sure that PSP battery is fully charge and plug it in the charger while updating..
Below where the UMD game appears on screen try the button below that should say 'Update PSP'. The game could have an update for the PSP and won't play without it. If this doesn't work contact Sony Website Forums and see if anybody there has had the problem.
cannot start umd or cannot start iso file? if your psp cannot start an iso file,then you must update your cooked firmware to play recent games.see www.pspiso.com for more info about this. if your psp cannot start an umd,then take it to nearest Sony Service Centre.
If you have custom firmware, make sure your "execute boot.bin" and "plain modules" are both disabled under your advanced configuration settings of the recovery menu. Also, make sure your ISO/CSO games are saved in the ISO Folder of your memory stick and that your UMD MODE is set to NO UMD REQUIRED. Your PBP Games should be saved in your PSP/GAME Folder.
What version did you update to? most likely the lens is just dirty a little alcohol and qtip and the lens can be cleaned but be sure to be careful. You can also buy a cleaning disc as well. If you need further assistance let me know, also please take a moment to accept and rate my solution accordingly. Thanks, Lee
alright turn off your psp by holding down the power switch for atleast five seconds. when it is turned off hold down the right trigger (the R1 button) then at the same time hold down the power switch button to get to the recovery menu. after that go to configuration then somewhere amongst all of the displayed lines one of them should either say no umd or umd required toward the end of the text. if it says umd required change it to where it says no umd. then go back and go to advance then advance configuration and disable all and this should solve your problem. hope i helped.
Not a bid deal for the psp region, all psps are made in china and make no difference if it's a hongkong, taiwan, uk, ect ect.
You need to switch it off. Hold R trigger and switch it on, go to recovery menu and set the ISO UMD Mode to M33 DRIVER OR SONYNP9660 DRIVER, which will enable to play games like ISO or CSO that you own legal copies without the proper UMD disk.
you may need to downgrade your PSP for some Games require a lower "." number.
there is a way to save your "3.40 and OE-A Firmware" loads on your computer to load again for another days gaming... however, i don't know how to do that.
