How many PSP folders are there suppose to be on the memory stick?

Only one by default... but it wouldn't matter if you had more.

I upgraded to 3.50 using my 4GB stick and I tried downgrading to 1.50 following the instructions given in the zipfile from the creators of the exploit and it didn't work...

My PSP is a Japanese Ceramic White version, [Original Firmware was 2.01 before being upgraded to 2.71 and 3.40 and 3.50] and my copy of Lumines is the European non Platinum version which has the 1.50 Firmware on the UMD.

EDIT: It's OK... I finally got it sorted out after much anguish and tears! :)

Why wont it get dark and light blue when i start lumines

Hey there i totally respect your guide for downgrading but there is one thing which doesnt work for me and its the 3. Load Lumines and press X to start the game. The screen will clear to black and fill with a light blue color, then the PSP will return back to the XMB. If not, try again. Well my screen didnt turn black and didnt do anything at all just did what its supposed to do i tried it over 50 times still doesnt work... i repeated everystep trying to find mistakes but so far i think i have no mistakes at all any help will be accepted please :confused1:

It started the Lumines game as normal then? Did not return to the XMB?

You don't have the files in the correct place then. Try copying over the PSP folder again.

EDIT: Please don't double post...

Still didnt work but maybe i understood this instruction wrong ? 2. Download the 1.50 update. Ensure that it is named UPDATE.PBP and copy it to X:/PSP/GAME/UPDATE - DO NOT OVERWRITE PSP/GAME/UPDATE/EBOOT.PBP! Do i place the UPDATE.PBP into /MS_ROOT/PSP/GAME/UPDATE OR into PSP/GAME/UPDATE?

ms0:/PSP/GAME/UPDATE.

you don't put the MS_ROOT folder into your ms. go into the MS_ROOT folder, THEN copy all the contents INSIDE the MS_ROOT folder.
i suggest formatting your memory stick and try again.



x3sphere said do not double post. and you did it again. it's going to be a warning if you double post again.

if you posted and you want to add something use the EDIT button on the bottom right of your post and then add in what you want to say. :)

Hm i formatted it now but it seems that my MS_ROOT is called MP_ROOT on my PSP for some reason. Is that normal and am i double posting again?

nope not this time. MS_Root and MP_root has nothing to do with each other
you go in MS_ROOT you'll see a PSP folder right? copy the PSP folder and then overwrite the one in your ms stick.
is this clear? if not i'll think of another way to tell you....:D

K i haven't bought a psp yet but if i go to my nearest wal-mart and buy it, what will the firmware be? 3.51? or 3.50?

Should be 3.50... I don't think they sell PSPs with 3.51+ yet.

Good news. Or, if you have a janky Wal-Mart in the middle of nowhere like mine it'll probably have like 2.71 or something.:p Well, up until about two weeks ago- we just got the biggest super Wal-Mart in the country, actually, it's kinda crazy.

You're f@cked, buddy- there's nothing you can do but wait. We have no idea if there will be a downgrader any time soon, if EVER, for 3.52.
