How to Downgrade 3.50 psp's to 1.50 Firmware using Lumines

i have a psp firmware 3.11 and my friend has one thats 2.71 i think but i want to know would this work without it beeing firmware 3.50

how can i downgrade my psp 3.8 back to 3.71...please help

what if i dont have lumines??is there other psp games that can be used to downgrade psp??

what keys do I have to press to start the game as normal ? the down key and X together?

OMG THIS SONG PWNS WHAT IS IT CALLED

(My firmware is 2.81) A few points that are differnet when i atempted this: First in my removable drive folder I dont have picture and videos folders there in the PSP folder when your video shows that they are out side the folder. Anyway, i ignored this and deleted the psp folder and replaced it with the MHPSP zip. I then inserted lumines. I got it of ebay advertised as a downgrader version. I looked on the umd and it is differenet from yours U say use ULUS1002 on yur video. Mine is a ULUS10002. I don't know if u forgot to put a zero in there or if the ebay seller ripped me off. After all this i start lumines, press x etc but instead of the screen flashing red for a second the blue it just stays red for a minute and then goes black and the power turns off? I have a full battery and the machine is plugged in the wall. Pls tell me wha tim doing wrong.

do i have to delete the music and videos before downgrading ?

How do I downgrade 3.80? ( not m33 or OE)I need to downgrade it to 3.71 m33 PLEAASE HELP

m8 can I have your msn addy so maybe you could help me through the downgrade pleae

Just to confirm will this process work on a white slim psp thats currently got firmware of 2.60 on it ? Thanks

dont post back to stupid questions mike

these ppl are retarded, love ur tutorials. they are all on his site if u cant figure it out well ur retarded. thanks for all the tutorials mike. and props to dankista and in7ane

Your tutorial is excellent. It couldn't be any easy. Worked perfectly on my fat PSP. Thanks for your efforts.

did you know where else i can download this files(mhpsp.rar)because i have already downloaded and when i try to opened it say that they where damage

what will happen if i have higher firmware I have 3.93 what will happen if I try to use this on my psp

I'm wondering if this will crash my psp cause I'm trying to do this but I don't have Lumines.

I have the ULUS10002 copy of lumines and have downloaded the mhPSP.rar file posted above. After following the instuctions above i get a " Save data is courpted" after starting the Lumines game normally. Can I get another copy of mhPSP from somewhere else or am i doing something wrong. PLEASE HELP!

If anyone is having trouble with this hack go to :
www.mediafire.com/?sharekey=0596f753856a61e1d2db6fb9a8902bda
Download the file and follow the directions. Worked for me, No problem! You dont need the Lumines disk, just 1 battery. WARNING After Hard Modding the pandora battery you cannot use it effectively. Another standard battery is required for normal operaton! However you can just use the power supply until another battery is obtained.

l just want to know what is the purpose to downgrad your 3.50 psp's to 1.50 Firmware using Lumines?
