Homebrew coder Zer01ne has released a useful plugin that is compatible with CFW 5.03 GEN-A and the recently released GEN-B. Sedna is a simple PRX plugin that allows you to stay in the custom firmware even if you accidentally shutdown or restarted your PSP without using ChickHEN.

Developer's note:
This plugin allow to:

Patch the Reboot of the PSP
Patch the Shutdown of the PSP
Hide UMD Update Icon
Patch flash 0, 1, 2, 3 USB acc?
Redirecting the file version.txt to ms0:/PSP/SYSTEM/version.txt
Patch the blit TIFF image "blit corrupted data for file with extension .tiff"

Installation:

Copy the folder seplugins in the root of your Memory Stick and copy this line ms0:/seplugins/Sedna.prx 1 in the file X:sepluginsvsh.txt, X:sepluginsgame.txt

Known bugs:

Some Reboot/Shutdown is still executed despite the patches apply.

Thanks to cmbeke and jhonn_5555 for the tip!

# .. — phoenix1414 2009-11-03 19:22

really awesome if this works out but im not going to try it until somebody confirms this as working. it mentions flashing some things so im all sorts of scared of a brick. so if anyone has had success with this let me know :)

How does this work?

Does it work even if you take out your battery. Or is it jusst if you use shutdown and reboot from the vsh menu?

# » — DSpider 2009-11-04 03:03

I think so. Because the ChichHEN exploit is running in RAM and RAM memory is emptied if there's no power to keep it alive. It most likely patches the "Reboot" and "Shutdown" entry from the VSH menu (the Select button).

Anyway, you would have to be pretty dumb to see what "Reboot" and "Shutdown" does in the first place.

# ^^ — DaniPoo 2009-11-04 03:55

well... atleast I cant accidently shutdown the psp from the vsh menu anymore. So conclusion.. The only ways to dissable the cfw now is: Shuting down the psp by holding up the power switch, Removing the battery or dissable the .prx plugin and then shuting down the psp from the vsh menu. I think.. Hahahe ^^

Anyway.. Does this mean that he switched the the shutdown function of the vsh menu with sleep mode?
