Yk my firmware is 4.01 m33-2 then i upgraded it to 5.00 m33-6…but when I run the games it says error…what should I do?
What is the error message that is displayed?
my firmware is 5.00 m33-6 but i get the message ‘the game could not be started’.
Which game are you trying?
Modnation racer.
The original version of modnation racer doesn’t work with 5.00 M33-6, you will need to search for a “fixed” version.
Okay thanks alot
well this sucks :/ my R button does not work and the screwws are in to tight so i cant fix it so i cant upgrade :/
my psp was “unlocked” by a guy., and he used his “magic” memory stick, and he pushed some buttons and now the psp is unlocked but it has a 3.71 m33-2 firmware..
and i dont know where is the folder “eboot”.. is it normal?
ehm, and if it is normal, can i update my firmware following your instructions?
because i dont want to broke my psp =/
hey bud i open d rar file but cannot extract it
some diagnostic messages pop up
When I start the 3.52 M33 Creator it said File 1.50.PBP couldn’t be opened. What do I do?
dv: If your psp is currently running CFW 3.71 M33-2, you should be able to upgrade.
Delz: The rar file that you downloaded is incomplete/corrupted. Try to download again.
Johnny: Did you rename the Firmware 1.5′s eboot file to 150.PBP as described by the steps above?
Yep same 5.00m33-6 and still get game cannot be started 800…….. etc error
Hey thank you very very much.
This is soo well written and clear. I managed to upgrade my psp firmware.
BTW: m33-6 link is broken. Here is another link: http://ifile.it/qjkfg0o
Just wanted to express my utmost gratitude to you, yk. I was updating my PSP-1000 for my girlfriend so that she and I could play SNES games together, but it’s been so long since I’ve installed any CFW, I didn’t even know where to start. Then I stumbled upon your guide and voila– simple, painless process with absolutely no problems. You sir, are a credit to our race! =D
Thanks for your comment, Andrew. Hope you and your girlfriend have fun!
when i try to install 5.00 M33-6 i get an error. i am currently using 4.01 M33-2
Hi mm, may I know what is the error message that was shown to you?
yk, you’re a legend! Not all the download links worked for me, but you can find the files easily elsewhere, and absolutely perfect instructions.
haven’t played a game that doesn’t work using this now (i’m on 5.00 M33-6), including Peace Walker. I’m now fully up to speed, thanks very much!!!
