Ok here is the deal:
I have updated my CFW M33 3.51-4 to M33 3.71.
I didn't know that the M33 3.71 firmware did not have 1.50 kernel support.
So I'm like w.t.f! I just ripped my UMD's onto my computer and was about to load it up on to my memory stick, but now It cannot run devhook.
So... I read around to see If I could downgrade M33 3.71.
And unfortunately yes, with the Recovery pack or Pandora's Battery.
Ok now I install the Recovery pack for downgrading M33 CFW's.

It gives me an error saying:

error: lflash_fatfmt.prx
error: ipl_update.prx

*not found inside flash 1*

So i'm stuck with M33 3.71.
Then I check the flash 1 files with Recovery mode and found out that most of my folders are gone! (maybe because of the new firmware?)
So I keep messing around with my flash 0 files and flash 1 files to see if I can fix the problem.
After rebooting I kept getting the blue screen of death constantly.
After many times of B.S.O.D. I get a fully bricked psp with no recovery option to load too.

Some of my questions concerning my problem.

1. Does pandora's battery fix FULLY bricked PSP's?

2. Does the memory stick 32mb work for pandora's battery or do you need a bigger memory stick? And are their any memory stick PRO duo that are 32mb?

3. With the unbricked psp does installing the files onto the memory stick effect any of the unbricked psp flash files?

4. What does it mean when it says:

- The firmware in the Memory Stick is not a full 1.50, but a minimal
subset. Therefore, not all applications (such as flashers, or
recovery apps) will load.

Will it be the same after you upgrade to a CFW such as M33 3.52-4?


Thank you for all your patients reading this and I hope you can help me out.

1. yes they do
2. no it dosnt. neeed atleast 512 i think
3. no it does not affect the psp you use to make the stick and batt with
4. have no clue

you need to just stay with 3.52 M33-4 until the 1.50 kernel patch comes out... and why are you using devhook still you dont need it

Yep. To play your UMD- ripped isos simply pop them into the folder ISO at the root of your mem stick alongside your MUSIC, VIDEO folders etc.
And I guess the answer to your question no.4 is that because the pandora's battery set uses a rebuilt version of 1.50 instead of Sony's(that is built by Team C+D) and so it is not the complete 1.50, but instead just a subset; and no, it will not affect you after you installed a cfw on your psp.
