Can I go back to 3.71 OFW for Slim by this Unbricker v3? I wanna return it to the store…

You probally would have to wait for a downgrader

it said u hit O after u have the whole thing made
It’s one of the selection when u start the psp with this Pandora setup

“Unbricking:

- Press X to install 3.71M33.

- Press O to install original 3.71 (rest of the process as the X option)

- Press [] to dump nand to nand-dump.bin. When done, psp will auto shutdown.

- Press L+R+HOME+start to restore nand from nand-dump.bin”

Will this work on a PSP Slim with an original 3.71 FW?

ok guys i am confused i have a pandora memory stick i simply have to put the 150.pbp 340pbp and 371 pbp on to the root of my memory stick is that it
or i have to do something else also plz explain

- Copy despertar_cementerio to PSP/GAME/

- Download 1.50, 3.40 and 3.71 update eboots and copy them to ms root with
150.PBP, 340.PBP and 371.PBP names.

previous instructions by other poster cautioned the use of the new PSP slim battery..

1, is this still so for this “new” instructions?
2. will the old battery work for the new psp slim?

tnx

Yes the old battery will work in the PSP Slim, however never use the PSP Slim battery.

tnx psp-fan.. ill buy an old battery tomorrow and try it out.. sorry, am new with this stuff..

I’m new to this whole unbricking thing…I have the new PSP Slim….and I’ve followed the directions on the read me and on this page, but everytime I go to start the application it says “The game could not be started. (80020148)”. What am I doing wrong?

ok here i am again.. just to set things straight..

1. the old fat battery DO NOT WORK for the new psp slim
2. it hardly fits into the battery case and you DEFINATELY cannot close the case anyway

i returned my psp slim and exchanged it with the old fat psp instead..

now i am stuck..

Download 1.50, 3.40 and 3.71 update eboots and copy them to ms root with
150.PBP, 340.PBP and 371.PBP names. (DONE)

- Use the app under a cfw with 2.x or 3.x kernel (be sure that kernel is
selected on recovery to the correct one (2.x or 3.x)) (????)

as a noob, i am totally clueless as to the instruction above.. i hope somebody can clarify that step..

again, many thanks for any help on this..

I have a PSP slim 3.71 version
I heard that I can use unbricker version 3 to go directly to 3.71 without the pandora battery part is that tru?

Desprategirl—

i have psp slim the battery does fit. I did it and it worked perfectly the lid doensent close but the battery will fit in the slim their was no need to go and exchange for the fat psp.

All worked fine for me. Many Thanks.

However I have noticed that initially when going into PSP after installation of CFW the screen is very bright and so I have to go to theme and re-apply the theme for original inorder to display the menus clearer……But when going into games they seem to be that much more less in contrast/brightness/sharpness. Also when going to save or load the screen at this point goes very light again as it was just after hacking??……This occurs with the FAT and Slim PSP’s??

Any fixes for this?

Thanks

i cant get my psp phat to run homebrew… it got a TA-082, and the new kind of battery and i cant get my pandora battery to work… when i start the program i get 80020148… help me..

justin sprry long time away from pc work turn psp complete off {by holding off button up untill off} then turn psp on and hold down the right trigger this will enter recovery mode press x on config then go to kernel press x should change 150
hope it works for ya

Help,

I have a psp slim it had 3.72 OFW I used the Universal Unbricker like you stated. It all loaded fine yet when I start the psp all I get is the time and date in the upper right hand corner. I can boot into recovery mode without issue.

Any suggestions?

Thanks

I figured it our I reset the flash 0 settings and it reset the standard settings and it works great now.

hey guys ive been reading about the psp custom my mate has done it for loads of people he does it for money im getting s black psp slim for christmas will it work on it?

Use the app under a cfw with 2.x or 3.x kernel (be sure that kernel is
selected on recovery to the correct one (2.x or 3.x))
wat does the above statement mean???
and how do u knwo if your psp slim is fully bricked or semi-bricked??

will this work on ofw 3.80?

the 3.40 download doesnt work!! dammit!

This guide actually worked perfectly fine for me. Just one problem though, every time I put the battery into ANY PSP it auto starts the unbricker/downgrade. Of course I chose custom firmware 3.71 M33 to be installed. When I finished installing it, I push X to shut down PSP and then I turn it back on and get the same menu again. The only way for me to get pass this menu is to pull the battery out and plug the adaptor in. Any other solutions?

NOTE: The good side of this is that anyone can give me their PSP as OFW and all I have to do is put the battery into their PSP and it becomes custom firmware.

hi mad props to you. I really need your help i have a slim psp 3.72. is there anyway to hack it so i can play downloaded games or copy games? can u please e-mail me at ravewite@hotmail.com thanks a bunch

Unbricking…

My fat PSP had Dark Alex’s 3.40 OE-A for a long time. Tonight I tried to use Pandora to install 3.71 M33 and instead I ended up seriously bricking my PSP. How can I get this thing unbricked aside from sending it to Sony? I was able to use the UPMS to create a pandora MS and battery, as far as I can tell, but the first time I tried to boot into the UL the thing bricked on me instead. Now when I go to power on the thing just lights the power light, no bootup, black screen.

my psp (4.01 m33-1) phat is semi bricked and will not do any of the multiple recovery processes i have also learned that i might be missing some flash1 files my inexperienced self may have deleted them well most likely is there a way i can get those file listed and a site to download?i just may have to replace the flash files or what so send me an email

do u need a pandora’s battery to do this? I ‘m not really sure what to do…

Thankssssssssssssssssssssssssssssssssss soooooo much
