i open the update in my psp, but it says this "it wasnt possible to start the game.(80020148 )" help please!

At 4.05, there's no direct upgrade path to custom firmware unfortunately. However, depending upon the model and mobo revision you may be able to install 5.00 M33 on it using a Pandora battery. There are several guides that will help you identify this information.

If you find your PSP is incompatible with the Pandora method, there are other alternatives, like ChickHEN. Do a search.

Well, yes, provided you have at least updated to 3.52 M33-3 or higher. The 5.00 M33 installer will not run otherwise.

Great tutorial and easy to follow.

The problem I am having however is that all my saved data is corrupt and won't load. Can I fix this? If not then one of the steps in the tutorial should suggest that users backup their data first.

If it's the problem I'm thinking of, your saves aren't entirely corrupt. They will still work on the firmware you upgraded from. It seems like a mismatch of decryption keys causes it, perhaps earlier M33 revisions did not save properly, although I've never experienced this myself.

Check out Savegame Deemer, it can decrypt and load the resulting saves. It may fail if the FW itself lacks the necessary keys, but worth a try anyway.

Thank you for your quick reply x3sphere!

I did some research this afternoon on the web and it seems that loads of people have similar problems although no real explanation why upgrades won't run saved data from games run in previous version.

All I did today was upgrade my psp from 3.90 M33-2 to 5.00 M33-6 with the 5.00 M33-6 Easy Installation Guide tutorial from this thread (and a bit of help from january39).

The upgrade worked a treat and everything seems fine i.e. games work, I can browse the internet etc.

So decided to play a game and load my saved game (which was last played on 3.90 M33-2) but I got an error message saying unable to load file due to the file being corrupt.

So I continued to search the web and came across loads of people having similar problems and found this http://www.maxconsole.net/showthread.php?137188-Corrupt-Saved-Game-on-MHP2G-after-firmware-upgrade. But I'm not having any success because at step 5 when I come out of freecheat after selecting dump memory mode my screen goes blank but I can still here the game music. I try and save the game etc. but I just can't get to convert my saved game into a playable saved game file.

Thank you for posting savegame deemer. I'll check it out and hopefully it will work.

Wow, it's extremely easiest way of upgrading my 3.71 M33 to 5.00 M33-6. Thanks !

But I face a couple of problem after that, I don't care about reading the savedata from prev version, but:
1. When loading an iso, it shows "The game could not be started. (80020148 )"
2. Or, for some iso, it just loading with blank screen and non-stop. and can't be reboot, I had to remove the battery to reboot it.

Any idea how to fix it?

Try changing the iso drivers. Also, some games only work with 371m33. So if you want to carry on playing your old games, install time machine

Blank screen is due to the filename contains non-english character, the games worked after removing the character.

error-80020148 was because of the file was corrupted (i think), download the file again from different source, it works!

Thanks.

Have you tried with the UMDs to ensure that it's not just a bad ISO rip you made?
