Ultimate flash0 Free Space Guide
The contents of this guide will consist of information NOT listed in most other free-space-guides.
This involves manual work on flash0 so I highly recommend keeping a backup of the file in question.
Useless files you can delete without concern of feature loss or the need to backup:
Unpopular XMB features taking space:
Relocating movable and / or customizable components of the XMB to flash1, flash2, or ms0:
DO NOT TRY FLASH3, it is NOT mounted during any mode on any firmware.
Download and install Hex editor:
Download the Official Sony Update firmware (pbp) which matches your current version.
1.50 Official Sony Update (pbp)
3.71 Official Sony Update (pbp)
3.80 Official Sony Update (pbp)
3.90 Official Sony Update (pbp)
3.93 Official Sony Update (pbp)
3.95 Official Sony Update (pbp)
4.01 Official Sony Update (pbp)
4.05 Official Sony Update (pbp)
5.00 Official Sony Update (pbp)
Download New PSAR Dumper 5.00:
If the file you're looking for is not on this list, that's because it hasn't been tried yet. Try it yourself and report your findings! Make sure you have your backup (which you will read about shortly) before trying anything though.
List of files which can be relocated:
List of files which cannot be relocated:
1. Place the Official Sony Update (pbp) in the root of your ms.
2. Install New PSAR Dumper v5.00 (check the readme for install instructions, if it doesn't work after you installed it then refer back to the readme).
3. Confirm that your kernel is set to your currect firmware version.
4. Launch and decrypt all with SQUARE.
5. Acquire vshmain.prx from the location on your ms:
*Highly Recommend* Rename the decrypted vshmain.prx to something other than it's original name, and place it on your Desktop.
6. Connect your flash0 to usb.
7. *MUST* Acquire vshmain.prx backup from the location on your flash0:
Place this on your Desktop, and remember, this is your back up of the only file in danger.
8. From the Desktop, right click the decrypted vshmain.prx and select "Hex Edit with Hex Workshop v5.0"
9. Right click anywhere in the center box.
10. Make sure it's on Text String.
11. Type in the value flash0 and click ok.
12. Check all of the Results in the bottom right box...
...until you come across the file-paths of the files you wish to relocate to flash1, flash2, or ms0.
13. Change flash0 in the right box...
...to flash1, flash2, or ms0.
14. Click "File" and "Save As" to get your modified vshmain.prx
MAKE SURE YOU MADE A BACKUP OF YOUR ORIGINAL vshmain.prx (step 7)
Put your modified vshmain.prx in:
15. Cut & Paste the files of the file-paths you changed to your Desktop and connect flash1, flash2, or ms0, whichever you selected, to usb.
16. Create the file structure in which the file you're moving originated (or to resemble the custom file path if you decided to make one) in the drive you chose to relocate the files to. Drop the files off of your Desktop into their corresponding folders.
17. Reboot your PSP. All should be well.
18. In the event something does not work:
A. Replace the modified vshmain.prx via Recovery Mode at flash0:/vsh/module/ with the backup vshmain.prx from your desktop.
B. Return the moved files to their original folders.
if you meet every step of this guide, you will have 4-6, possibly 7mb free on your flash0 WITH 1.50 kernel subset installed.
on slims, the freespace numbers may get pretty big please report them if you try it.
Don't do anything stupid :thumbup:

Well, when i originally posted this, it wasn't completed, so the blue text wasn't there. But that is a MASSIVE amount of free space.
I didn't follow everything, But i deleted (on CFW 3.90M33-2, without 1.50 kernal installed) Camera_Plugin.rco and ps3scan.rco and replace the 3 font files and have 5.96MB free space. Very very good guide.
sounds cool and all but how exactly is this helpful? what will i be able to do with more flash space? i just dont like messing around with flash0 unless it does something significant (go gameboot.pmf!!!)
i, unlike some other people, know what i'm doing, and know what is / isn't dangerous. therefor, flash0 is my playground.
myth: will the nand wear out after being written on excessively?
not at all, unless you write to it insanely more frequent than you would to a memory stick.
