Pandora and MMS not booting... anymore

[shafropuff]

I got a Pandoras Battery a few days back and I've gotten my PSP2000 onto CFW using the "KD and Registry files for Magic MS" download from this site everything went fine and been pretty much having fun...

However last night I downloaded the 5.03 update for my PSP3000 and I was copying saves over from the 2000 to the 3000 as I wanted to format the 2000s stick and return it, due to finding out it was a fake (Used a real 1GB for this)

Anyway I ended up booting the 5.03 update on the wrong PSP and now my 2000 had be unCFW'd and my MMS and Pandora Battery are not working on it anymore... also still using the same official 1GB memory card and I've tried multiple different MMS creation guides but nothing, just stays a black screen with the green light on but no memory stick light no matter how many times i take it out and put it back in...

Is 5.03 blocking them?

the reason you see this black screen is the psp is trying to load system files from the memory stick, but since these files no longer exist the psp can not properly load or start you need to make a new mms use pandora deluxe and this guide if you need help just ask.

Tried it a few times... but memory stick kept switching the PSP off and I tried multiple different options then eventually one with just DDC3 and DDC8 but the same thing kept happening then I removed the elf. file from the mem stick and it worked ^__^

So thank you...
