GUIDE: How to Recover semi-brick PSP SLIM

Excellent guide but I got one question.

Forgive me if I have missed something, I've read so many guide I'm starting to get confused.

Ok, so using this guide I am able to convert the standard slim battery (PSP-S110) into a pandora battery then turn it back again buy using the OS Pandora Battery Tool. I don't need to modify the battery physically or need a orginal phat battery (PSP-110)

Thanks.

 

If you have a compatible SLIM battery yes you can convert it to a Pandora using the OS Battery Tool.

 

Basically you take a risk with any modification.
Mine was not saving the serial and it cost me a battery. So what i can tell you is yes this works. It will turn your factory Slim battery into a real working pandora battery without having to futz with cutting or modding the internals. But since i did not save my factory battery serial number I can't tell you if the factory slim battery will go back to normal.
But you can...if you do this please come back and give us an update if it worked or not. So future people can get a better idea on how well it goes from Pandora back to normal.

 

It already has been tested and does work on PSP SLIM Batteries. I wouldn't post if if it didn't.

 

when im in recovery mode after dragging the recovery folder into
PSP/GAME i press the run program at PSP/GAME/RECOVERY/EBOOT.PBP i get this thing that says there was an error running the batser.prx and then i end up in the xmb. in system settings it says that im on 3.80 M33-2. could someone please help me here.

i ran the OS Pandora Battery tool 0.3 from xmb and then i got the same thing
please help

ERROR:AN EXTENDED MEMORY MANAGER IS ALREADY INSTALLED.
XMS DRIVER NOT INSTALLED

is this the problem??

 

I have read that OS Pandora Battery tool, UPMS and Hellcats Pandora Tool will not work on 3.80 M33. They will need to re-write the code for 3.80 M33.

UPDATE: HERE is suposiddly a plugin for a Pandora Creator for 3.80 M33

 

yea i tried that and it didnt do anything really
do i just have to make a pandora battery with another psp and then do it or am i screwed till they re-write the pandora tool for 3.80 M33??

 

The only side effect this has is not being able to use the Battery Tool Application itself on the 3.80 M33 custom firmware. You can still use a Pandora Battery on it to recover back to 3.71 M33-2 with an unbricker.

But you will need to use a PSP with custom firmware 3.71 M33-4 or below when converting the battery to a Pandora Battery.

 

ill try that out then since my friend has 3.52 M33-4
thnx for the help

 

Hellcat has fixed it

ok now i am up to this step :
Now take out the Battery from the PSP then reinsert it back in (make sure the AC Adapter is not plugged into the PSP).. The Universal menu should come up letting you reinstall 3.71 M33 to the PSP SLIM.
Instead of a menu popping out, the screen just went blank and nothing comes out at all, all it does was "powered on"~ cant go back to recovery mode as well ! help!

edit: oh one thing to be mentioned, is that this step :

After it has finished writing the files you will get an image similar to below. Just type Y and ENTER to finish the instillation of files to the Magic memory Stick.



was never shown in the installer, all it ask was press any key to close...

 

ok, now i can boot it into XMB and was able to go in to the Pandora's battery tool in the game folder, however, the option to revert the battery back to normal was greyed out. Assuming that the backup file was deleted during my second attempt with the restoration, what can i do now? is there any way to revert it back to normal now? or do i need to use another battery ,ie, buying a new one. I am able to boot into XMB only if my AC adaptor is plugged in, if i use the battery which was modified , it goes back to asking me if i want to install the CFW... hmm and is it bad to play games with that modified battery installed?

 

thank u lots now my psp started working but pls can u tell me how i can play iso files(games) on my psp

 

If you have an iso file, you can just copy the file to your ISO folder in your psp drive. ie:X:\ISO At least that's what I have to do.

 

hey please help whenever i try to download that package of all the files from sendspace it never gets to 1% because it always comes up with an error that says cannot download from sendspace, the operation timed out.and whnever i use my download manager(orbit) it just stops downloadn befor it gets to 1%. COULD someone PLZ upload this to another site?? eg. RAPIDSHARE???

 

Try using your browser's downloading tool? It might take some time, just keep trying, because that's what happened to me as well. Goodluck.

 

I have added a link to Media Fire for those having issues with Sendspace.

 

it still wont download for me! we do have crap internet connection so that could be the problem exept i can download movies and torrents fine. any suggestions on how to make it work?

 

Don't know what to tell you I can download both parts fine plus the sendspace 1.

 

Well you might have to wait until someone uploads it as a torrent file or something? At the moment, I had downloaded too much and now it has exceeded the limit, so I can't help for now =(
