Note: that this guide is mainly intended for 3.XX OE firmware, not 1.50 or 2.71 SE-X, although there will be some parts pertaining to all three. Non custom firmware users are unable to recover from accidental bricks.THERE IS A CHANCE OF BRICKING EVERY TIME YOU MESS WITH THE PSP's FLASH MEMORY!!!
I AM NOT RESPONSIBLE FOR ANY DAMAGE DONE TO YOUR PSP!!!!! DO THIS AT YOUR OWN RISK!!!!!

Things needed:

1) A PSP with 3.03 OE-C or 3.10 OE-A custom firmware. No other versions.
2) Knowledge of copying/pasting/renaming files.
3) Ability to follow instructions to the letter.
4) Some common sense; only do this if you are comfortable with it/sufficiently bored.


Procedure:

1) Go to the recovery menu. If you don't know how to get there, I advise you do not continue past this point.

2) Go to advanced, then click toggle USB (flash0). Your flash0 should now appear as an external drive on your PC.

3) Create a folder somewhere on your PC, and copy everything in your flash0 into it. This folder will be needed if you screw up and do not wish to do a complete reflash.



Step 1: If you want Japanese/Korean/Chinese fonts, skip this step. For 99% of people this is the only step needed to be taken.

Go to x:/font. Copy and paste ltn9.pgf twice, this makes two copies of the same file. Delete jpn0.pgf, and rename one of the copies to jpn0.pgf.

Delete gb3s1518.bwfon. Rename the second copy of ltn9.pgf to gb3s1518.bwfon.

You now have 2,545KB/~2.5MB more space on your flash0.
----------------------------------------------------------------------------------------------

Step 2: If you want to use the web browser/flash player skip this step.

Go to x:/vsh/nodule. Note that's nodule, not module. Remove htmlviewer_plugin.prx, htmlviewer_ui.prx and htmlviewer_utility.prx. Go to x:/vsh/resource. Remove htmlviewer.fbm, htmlviewer.gim htmlviewer.msg, htmlviewer.res, htmlviewer.snd and htmlviewer_plugin.rco.

You now have 492KB/~0.5MB more space on your flash0.
-------------------------------------------------------------------------------------------

Step 3: If you want to play mp3s or music on your PSP skip this step.

Go to x:/vsh/nodule. Remove music_main_plugin.prx, music_common.prx, music_plugin.prx. Go to x:/vsh/resource. Remove music_main_plugin.rco.

You now have 623KB/~0.6MB more space on your flash0.
-------------------------------------------------------------------------------------------

Step 4: If you want to view photos skip this step

Go to x:/vsh/nodule. Remove photo_plugin.prx. Go to x:/vsh/resource. Remove photo_plugin.rco.

You now have 232KB/~0.2MB more space on your flash0.
-------------------------------------------------------------------------------------------

Step 5: If you want to play videos skip this step.

You now have 802KB/~0.8MB more space on your flash0.
------------------------------------------------------------------------------------------

Step 6: If you want to use the RSS features skip this step.

Go to x:/vsh/nodule. Remove rss_subscriber.prx. Go to x:/vsh/resource. Remove rss_subscriber.rco.

You now have 21.1KB/~0.02MB more space on your flash0.
------------------------------------------------------------------------------------------

Step 7: If you want to use the Network Update icon skip this step.

Go to x:/vsh/nodule. Remove update_plugin.prx. Go to x:/vsh/resource. Remove update_plugin.rco.

You now have 33.6KB/~0.03MB more space on your flash0.
--------------------------------------------------------------------------------------------

Step 8: If you want to use the PSP Camera addon skip this step.

Go tox:/vsh/nodule. Remove camera_plugin.rco. Go to flash0:/vsh/resource. Remove camera_plugin.prx. Go to x:/kn. Remove usbcam.prx.

You now have 277KB/~0.3MB more space on your flash0.
-------------------------------------------------------------------------------------------

Step 9: If you want to use the PSP GPS addon skip this step.

Go to x:/kn. Remove usbgps.prx.

You now have 15.4KB/~0.02MB more space on your flash0.
-------------------------------------------------------------------------------------------


Final step: Only if you have end up and get a semi-brick. If not, this can be ignored.

Go to the recovery menu and re-enable flash0 access via USB. Drag and drop everything in your backup flash0 folder back into your flash0.

Alternatively if you'd rather start over, you have two choices:

1) Return to 1.50 and reflash custom firmware.
2) Reflash 3.03 OE-C or 3.10 OE-A directly.

This guide explains how to edit some things on the flash chip of the psp where the firmware is kept , as the flash chip has a limit of 32mb , so if we wanna install for example icons , etc and coldboots(opening movie) then we need to clear up some space . btw flash0 stands for root of the flash memory drive! .

INFO: The flash mem of the psp is non-volatile , but if it gets corrupted due to corrupt data , then the psp becomes bricked i.e un-bootable.

CAUTION:
~SO BE VERY VERY CAREFUL WHEN EDITING THE FLASH FILES ON UR PSP!

There's a new software out that frees space on flash0 so theres not much use for this guide now.
