A few question if i may ask.

Does the firmware dump require it to be on the same region? Like a Jap PSP needs to have a Jap firmware dump. That maybe the key to succesful upgrade. Its just a theory. I have never been involved in the homebrew scene. I came up with this theory when i saw the different firmware updaters and the different firmware dumps.

Can anyone reply asap? Thinking of doing the downgrade.

I'm pretty sure i know what most people who bricked their PSP's are doing wrong (and feared this as soon as i read the downgrading instructions).

While to me its cliear that the files INSIDE the MS_ROOT folder go on the root of your PSP, some people are going to inevitibly put the MS_ROOT folder itself in the ROOT of their PSP. So they would have

PSP:/PSP/PHOTO/Tiffile.
PSP:/MS_ROOT/(Downdaterfiles)
PSP:/DOWNDATER/
PSP:/MP_ROOT/

/\ WHICH IS INCORRECT.

Supposed to be:
PSP:/PSP/PHOTO/Tiffile.
PSP:/(Downdaterfiles)
PSP:/DOWNDATER/
PSP:/MP_ROOT/

One person admitted to this already (but still doesn't know what they did wrong) here:

So yeah, be careful with the directions. If you follow the directions perfectly, have a good firmware dump, and your PSP is NOT a TI-82, this is 100% working!

u can record another succesful downgrade, i just downgraded my cousin's PSP on the 2nd try. I bought myself a used psp sunday, searching for @ least a 1.51 - 2.0 relentlessly, (i found a 1.52, that i downgraded to 1.5 thankfully) thinking there wasn't gonna be a 2.7+ exploit any time soon....man was i wrong

. GOOD JOB!
