HOW 2 HACK URE PSP USIN ONLY THE RETAIL PACKAGE WIV LATEST CFW, 3.80M33-UPDATE 5 (NO PSP REQUIRED)Question : I want to install homebrew on my psp slim but i have no access to another psp, can i install it by just using the retail package?

Answer : Yes you can, well nearly (?) - you'll need another memory card.
Ok, you've got your brand new shiny psp slim but you want homebrew on it. Just follow this guide, it's for noobz and maybe pro's. Lol.
IT USES THE LATEST CUSTOM FIRMWARE, 3.80m33-5 AND THIS GUIDE WILL WORK ON ANY PSP VERSION. IT'S THE EASIEST SINCE NO SPARE PSP IS REQUIRED AND THE SOFTWARE IS VERY EASY TO USE.
Im sorry i don’t have any images up, i was just a bit busy.
AND I TAKE NO RESPONSIBILITY FOR ANY DAMAGE THIS GUIDE MIGHT DO TO YOUR PSP, BATTERY AND MEMORY CARD AND I ALSO TAKE NO RESPONSIBILITY FOR ANY INCORRECT INFORMATION THAT MIGHT BE IN THIS GUIDE because i am new to this forum, new to writing a new post and new to hacking psp’s . But truss, this guide will work.
THINGS YOU'LL NEED:
1.
ANOTHER MEMORY CARD (The retail memory card is too small) - It should be a genuine Sony Pro Duo one but others may work - 256mb - 4 GB should work fine even an m2 micro with an ms pro duo adaptor will work. eg. sandsik.
2.
ANOTHER BATTERY (optional) must be genuine sony or similar, made in china or japan and FULLY CHARGED.
3.
SOME SOFTWARE - this contains the hacking files, cfw etc which will be installed on the memory card.
NOW IF YOU WANT TO INSTALL 3.71M33-4 CUSTOM FIRMWARE FOLLOW THE GUIDE BELOW, IT WILL ALSO SHOW YOU HOW TO UPDATE TO 3.80M33-5. BUT IF YOU WANT TO GO STRAIGHT TO 3.80M33-5 CUSTOM FIRMWARE GO TO THE BOTTOM OF THIS GUIDE.
STEP1: download the software needed, follow this link -
http://dl.qj.net/TOTALNewbi-easyInstaller-PSP-Tools-Utilities-(on-PC)/pg/12/fid/14749/catid/193It basically modifies your memory card and turns it into a magic memory card
MAKE SURE YOU ARE USING WINDOWS XP 32BIT , IM NOT SURE IF IT WORKS ON VISTA. the download is big and is a bit slow, so leave it on flashget or whatever. After the download has finished, extract the file somewhere, eg. Desktop.
Forget about the downloaded file now, just remember where you put it and move to the next step.
STEP2 : You'll need a genuine sony battery, made in china or japan. The battery will be used to put your psp. You’ll need to MODIFY the battery to get your psp into service mode (don’t worry about service mode at the moment).
Japanese batteries also work as confirmed by Pheonix05

, i wasnt sure about it before, lol
Basically, you open up the battery using a screwdriver or a knife and you have have to DISCONNECT A PIN. Then it has become a magic battery or a Pandora battery.
Now There’s 2 options here: Option 1: If your good at electronic etc, you can use your original retail battery and modify it, install homebrew on the psp then after installation has finished, you can return the battery back to normal by re-soldering the pin. otherwise if you try to use the psp normally, it will just keep entering into service mode.
Option 2: If you’re not good with this kind of stuff then buy a datel tool battery, around £ 14 off ebay or amazon. This is just a normal battery which has already been modified (one of its pins has been disconnected) . The battery can be reserved and used later on if you want to hack someone else’s psp. Buy whichever size you want.(fat or slim)
Follow this link on how to modify the battery -
http://www.pspmod.com/forums/hardware/26181-guide-all-pandora-battery-hardmod-pictures.html Once you’ve modified tha battery, move on to the next step. Don’t put your battery into the psp right now. Just
LEAVE IT having an orgasm.
STEP3. You’ve got your memory card now so insert it into the psp slim and then connect ure psp to your pc and then run the application, the total newbie installer which was downloaded previously and extracted. Just double click on start.exe in the folder and a window will pop up.
Follow the On Screen Instructions in the DOS window. FOLLOW CAREFULLY.1) Press any key to continue.
2) Format your Memory Stick (make sure you have it backed up if you want anything saved). Then press any key to continue.
2) Connect the PSP to PC type the drive letter of the PSP into the DOS window when it ask for it. Then press ENTER key.
3) You now will get a message that says "Insert new disc for drive (your drive letter) and press enter when ready. You should already have the Memory card in so just press ENTER. It will then start verifying the Memory Stick.
4) Press ENTER for NONE when it ask for a Volume label.
5) It will then warn you that your about to format drive (your drive letter) and all data will be lost. Type Y and then press Enter.
6) the next prompt you get will tell you to take out the Memory card FIRST then disable the USB connection. Then press any key to continue.
7) The next prompt will tell you to put the Memory Stick back into the PSP and then enable the USB connection. Then press any key to continue.

you now will have a menu option to select what you want to do. Choose option 4 Universal Unbricker (Universal Unbricker for FAT and SLIM it's also a 3.71 M33 CFW installer).
The necessary files will then be written onto the Memory Stick. After it has finished writing the files you will get a question. Just type Y and ENTER to finish the installation of files to the memory card and It will then say "Write MS BOOT CODE" then press any key to continue.
You have now created a Magic Memory card.
Now, disconnect you PSP and then put your modified battery and it’ll power on and a menu should come up.
Press [] button to make a NAND backup of the psp. This should be done just in case anything goes wrong. It is basically a backup of the psp's structure and ipl etc. The NAND backup gets dumped into the root of the memory stick and it takes a while.
Press X to install 3.71 M33-2 to the PSP or
press O to install 3.71 official firmware to the PSP.
After it has finished installing the files you can then turn off the PSP and replace the Battery with the normal 1. If you modified the Battery you will need to unmodifiy it to get it back to normal use. Lol.
If you see some messed up screen just do the following:
turn on psp and press R to activate recovery mode
Goto advanced
Select format flash1 and restore settings.
then restart and psp will be arrite.
And that’s it, You've just installed 3.71 m33 cfw.
