Unofficial fix for the new 5.03 GEN-A (Full) firmware

[U3-Robot]

Installer "LAUNCH-ME.exe" copies these files to the Memory Stick:
1. Installer-Loader in the folder: ms0:/PSP/GAME/INSTALLERxxxxxxxx/
2. The Custom Firmware files, which will later flash to the Flash0 into the ms0:/files/ folder

The "LAUNCH-ME.exe" installer is same for the PSP-2000 and for PSP-3000.
But in the ms0:/files/ folder it copies different files and flashes to Flash0 different files.

For PSP-2000:
Pink - where are to they are recorded.
Green - which from they are recorded.

The files for PSP-2000 and PSP-3000 not so different and not all are different:
The difference between just 2 files:
The systemctrl_03g.prx file for a PSP-3000 has a few changes compared to systemctrl02g.prx file for a PSP-2000.
The recovery.prx file for a PSP-3000 has a few changes compared to recovery.prx file for a PSP-2000.
Binary files (*.bin), in which writen path to the GEN files, but the name of these for PSP-2000 has _02.bin at the end, and the PSP-3000 has _03.bin at the end but they are absolutely identical!

After decryption and verification of these PSP-2000's binary files found that these files have an error:
pspbtjnf_02g.bin
pspbtknf_02g.bin
pspbtlnf_02g.bin

Here are the contents of one of them:

As you can see in the paths is a mistake. They refer to the files that are absent in the PSP-2000.
These are the wrong ways:
$/kd/memlmd_03g.prx VGUPA
$/kd/systemctrl_03g.prx VGUPA
$/kd/loadexec_03g.prx VGUPA
$/kd/display_03g.prx VGUPA
$/kd/hpremote_03g.prx VGUPA
$/kd/umdcache_03g.prx G
$/kd/wlanfirm_03g.prx VGUPA
$/kd/mesg_led_03g.prx VGUPA
On the PSP-2000, these files are named *_02g.prx, and because of that, they will not be used.

So I corrected the errors in the three binary files.

Instructions. Only for PSP-2000!
1. Launch the "LAUNCH-ME.exe" installer and make the install for the PSP-2000.
2. Unpack the attached archive to the Memory Stick. (To the replacement alert, answer "Yes")
3. Go to the Game -> Memory Stick and launch "INSTALLER-LOADER" from there.
4. Press R to flash fixed files.
5. And then press O to load the firmware.

P.S. Sorry for bad English. Please comment. This will help me improve the article.
This fix also helped to correct the "recovery.prx" file, so it won't be like that:
Plugins = CPU Speed
This fix make ErikPshat, not me.

SPECIALLY FOR dna123300!!! (see attachment 503gen-for-hen-pspgen_1244249367.zip)

works great on a psp2000 mobo.

that recovery menu is really quite dangerous to unlock since there's no unbricker for t88v3 and 3k's

hope they made some security protection in future release so newbie won't mess around on the dangerous part that has been unlock.

BTW thanks you very much for discovering this!!

makes me wonder why they haven't released an official fix yet...seem 3ks are their priority

but i think i'll just stick to cfwe 2.51 it makes me fell that it's still safer to use

[afteralter]

a little of topic
