If you can access the recovery menu like Zhason said

Try this

# Goto advanced

# Select format flash1 and restore settings

This should hopefuly fix the problem

I will try that once I get into the recovery menu. Thank you guys. That makes sense from the original guide post...I won't be able to try Zhason's technique until I get home, but do you guys have any other suggestions? Should I be holding R first before putting in the battery, then tunring on the PSP? Of do I put battery in first, then hold R, then turn on? Or Put battery in first, then turn on PSP, then hold R? Or does this even make a difference?Could I have really bricked the thing? And do I really need to start with 3.60 CFW Blakey? If so, do you guys have those files/installer? I'm getting a little confused here...Should I even try dallyer's technique? That's gonna require I shell out like 10 bones for a card reader that I'm going to use once (I'd prefer to not have to do this...)Thanks again all!

jluu111 It's better to start with 3.60 cfw (this will solve your problem because I've done it with all my friend's PSP slim & after you have 3.60 cfw you can easliy update to 3.71 cfw, 3.80 cfw & 3.90 cfw latest) This is the readme for installing 3.60 cfw follow it and you will be guided accordingly...   Instalation:The instalation is done using pandora battery and requires a fat psp with 1.50 orcustom firmware with 1.50 support to run a installer. However once the memory stick installation is done, you can use it in whatever psp slim withoutrepeating the process again.We want to thank C+D Team for having created Pandora and having opened the path to custom ipl's,without which this cfw wouldn't exist.Steps:- Create a pandora battery and a pandora memory stick using the C+D team tools.- Run the fat psp with the pandora memory stick inserted, but with a normal battery. Copy the directories pandora_slim and pandora_slim% to PSP/GAME or PSP/GAME150.- Download official sony firmwares 3.40 and 3.50, and put them in pandora_slim directory with names 340.PBP and 350.PBP. To avoid confussion: These firmwares are used ONLY to extend the memory stick pandora kernel.  NOTHING FROM THOSE FIRMWARES WILL EVER BE FLASHED ON THE SLIM.- Run the program. It will quickly extract some prx's overwrting some of the pandora memory stick.- Insert the pandora battery and the memory stick in the psp slim. It will boot. You won't see  anything on the screen, because that kernel doesn't support the slim screen, but it is OK, you don't need a screen for the installation of 3.60 M33.From here, you have 3 options:- Press X to install M33. The process will last just few seconds, since the installer only needs to install the M33 custom prx's and IPL. After the process is finished, the installer will shutdown the psp automatically.- Press L+R+triangle to uninstall M33 and go back to original 3.60. Note: this can't unbrick a  psp slim, it will just remove M33 ipl. There is currently no unbricker for the psp slim, but we plan on doing one in the future. After uninstallation, psp will be shutdown automatically.- Press square to dump the PSP Slim nand. Watch out: you need 66 MB of free space in the  memory stick for this, otherwise your memory stick may end corrupted. This option uses the team C+D nand dumper. When the memory stick orange led stops blinking, the process will have finished, and you can either shutdown the psp, or use one of the two previous options.F.A.QQ: My homebrew doesn't work.A: as stated above, not all homebrews work due to 1.50 kernel missing.  Wait for the programmer of that homebrew to port it to new kernels.Q: How can i unbrick the PSP Slim?A: if you have a semi-brick, you can restore it using recovery and flashing the corrupted files  with usb flash. There is no real unbricker for PSP Slim yet, but we plan of doing one in the   future using C+D Pandora Battery.Q: is M33 gonna make a 3.60 cfw for the fat psp's?A: The firmware as it is flashed in the slim psp's is only for psp slims. Whenever sony releases  an updater, we'll support both, fat and slim psp's, but we are not gonna make a custom firmware  using 3.60 slim dump, because it is not done for the fat psp. Stop listening stupid rumors of kids:   we are 103% sure that Sony will continue releasing firmware updates for all psp's.  Â

Ummmm... Okay... I don't have a Phat PSP or know anyone with one... I thought I was able to install CFW all without needing a Phat PSP... Could you perhaps PM the files over to me so that I can copy them to my Memory stick? Or do I really have to get a hold of a Phat PSP???I see where you're coming from with copying the files from the Phat PSP, but I was really hoping that I'd be able to do this all with just my Slim PSP, a Pandora's Battery and files from this site...

I purchased a PSP Slim (PSP-2000) a few weeks ago, I am running OFW 3.80 and just recently received my Battery Tool in the mail...  I've created a Magic Memory Stick per your instructions using the CFW 3.71 (or is it 3.72?) Easy Installer...  But I seem to not be able to get the PSP into Recovery mode after it has finished installing the CFW...  Essentially, I'm having the same problem as Jaco (a bunch of posts earlier.)My first question is...  Do I leave Pandora's battery in the PSP when I try to enter recovery mode?  And second, if I do, why doesn't it enter (remember, I'm holding down R when the PSP restarts...)?  Because this wasn't working, I put in my regular battery and tried to boot up the PSP, and then I got the boot up screen (says Sony Computer Entertainment) then the red screen shows up (ala Jaco) and then it pretty much freezes up...Do you guys have any suggestions?  Maybe a different set of files for the MMS instead of CFW 3.71 Easy Installer?  And do I need to now use some kind of unbricker?  I'm quite confused now (I followed your instructions to a T and its not working...)Thanks!No you put your normal bat in when trying to access the recoveryJust hold right sholuder button when you turn on your psp<br><br>Post edited by: blakey87, at: 2008/02/05 14:43

Pretty sure I did that the first time, but I will try again when I get home and let you guys know how it goes.Thanks again!
