HOW TO INSTALL A CUSTOM FIRMWARE ON A PSP SLIM WITHOUT THE NEED FOR PHAT PSP(at all!) A lot of people Have made threads About Getting their PSP onto custom firmwares so I thought Id make one for GBAtemp. More specifically though this shows how to get a PSP slim onto CFW without the need for a Phat. This tutorial can also be used to get a Phat PSP onto CFW without a CFW PSP. The Steps that are below worked for me, but you are doing this at your own risk. It is not my fault if you screw up your PSP. The way to use this guide is pick a method for hardmodding a battery, then pick a method for making a Magic Memory stick I recommend using anime_junkie's method for hardmodding, and PSP Grader for making the Magic Memory stick. What You need HARDWARE: -PC (with Windows XP or VISTA(VISTA is still not the best option Windows XP Recommended, as VISTA wont work sometimes) -PSP Slim (obviously) or Phat PSP -Memory Stick Pro Duo (64 MB to 4GB in size, preferably 128MB or more) -Slim Battery OR Datel Tool Battery OR PSP Phat Battery IF YOU USE A SLIM BATTERY(e.g the one that came with your PSP) OR A PHAT BATTERY MAKE SURE THAT IT IS MADE IN CHINA, AS SONY HAVE MADE SOME BATTERIES THAT CANNOT BE HARDMODDED! I used the slim battery that came with my PSP Slim. SOFTWARE: -PSP Grader (THE EASIEST WAY TO MAKE A MAGIC MEMORY STICK DOWNLOAD FROM HERE) OR -TOTALNewbieasyInstallerPandorasmenu (Google is your Friend) Outcome: A Slim PSP with custom firmware and not a PHAT in Sight! HARDMODDING A BATTERY Slim Battery: THE FIRST METHOD IS THE BEST AS IT IS EASILY REPAIRIBLE Thanks to anime_junkie for this method Warning: Spoilers inside! ANOTHER METHOD Warning: Spoilers inside! First you need to open the battery up, which I did by prying it open with a Flat Headed Screw Driver. Remember, It is better to be cautious than stab the thing to death and break it. Once The case is open, lift up the circuit board. Locate the Chip Pictured: below it the letters "IC04" will be written upside down. (If your battery is not like this, i would probably advise against modifying it) And cut the the shown leg, I just used the scissors my Swisse Pocket knife, which did the trick nicely. Close Her Back Up!!!!!!! To test Whether it works pop it into your PSP, if its was made correctly the PSP will the automatically turn itself on but the screen will stay blank and the power Light will stay on and be green. AND ANOTHER METHOD Warning: Spoilers inside! Another way to convert a slim battery into a Pandora is to solder wire to the two points shown below. I have tested this method and can confirm it works as well. This image was taken from PSP Hacks(which they got from eurasia), which also shows how to wire a Phat battery. http://www.psp-hacks.com/2007/10/22/one-wi...uired/#comments PSP PHAT Battery: Warning: Spoilers inside! Pry it Open same as the slim battery. Once The case is open, lift up the circuit board. Locate the Chip. Cut the the leg. Close Her Back Up!!!!!!! For Pics and more details about converting a phat battery go to: http://www.pspmod.com/forums/psp-hardware-...ut-fat-psp.html To test Whether it works pop it into your PSP. If its was made correctly, the PSP will the automatically turn itself on, but the screen will stay blank and the power Light will stay on and be green. Charge your Battery Now so that when you are installing the firmware, it doesnt die. To charge, Plug in your power cable then put the battery in. CREATING THE MAGIC MEMORY STICK THE BEST AND EASIEST WAY USING PSP Grader Warning: Spoilers inside! DOWNLOAD FROM HERE Then download the official sony eBoot.pbp's(You are on your own here, not really that hard to find though) This program will format your memory stick so backup any needed files Install PSP Grader, then run it. PSP Grader will work on Windows XP or VISTA(But VISTA can be stupid, i recommend XP). In PSP Grader, browse to the locations of the eboots. select any IPL. If the magic memory stick doesn't work then try another IPL. Select the PSP's Drive letter(If you attach the PSP after you open the program it will automatically recognize the drive) Select Format memory stick. Click Create Pandora stick. If you haven't figured out that the memory stick will be formatted, you will now. It will copy the files to the memory stick. SUCCESS! Turn off Your PSP, Take out the battery, Put the Memory Stick in. HOLD THE L TRIGGER(If you dont hold down the trigger it will just boot like normal into the XMB) Put the Pandora Battery in while still holding L trigger. You will now see a menu with 4 options. Now press Square to make a dump of your nand. DO THIS BEFORE YOU INSTALL THE CUSTOM FIRMWARE!!!!!!!!!! YOU WILL NOT BE ABLE TO COPY THE NAND IF YOUR MEMORY STICK IS 64MB IN SIZE, AS THE NAND BACKUP IS 66MB AND THE FILES ON THE MEMORY STICK ARE 22MB. IF YOU DO TRY TO DUMP YOUR NAND ON A 64MB MEMORY STICK YOU WILL CORRUPT IT Warning: Spoilers inside! After the PSP has finished copying the nand, it will shut itself off. Take out the Memory Stick and Plug it into your PC and copy nand-dump.bin so you have it as a backup. Reinsert the memory stick and the battery, hold the l trigger down again, and once it is back on, press X. When the firmware has finished installing you can take out the battery, plug in the power cable, and when you turn it back on 3.80 M33!!! USING TOTALNewbieasyInstaller(use psp Grader, its easier, trust me) Warning: Spoilers inside! Extract TOTALNewbieasyInstallerPandorasmenu into a folder. (And as Icarus stated below, TOTALNewbieasyInstaller will not work on windows Vista, only XP) Format Your Memory Stick on your PSP via Settings>System Settings>Format Memory Stick You can Use TOTALNewbieasyInstallerPandorasmenu with your memory stick in your psp and attached to your PC from your PSP, or you can use it with the memory stick in the card adapter directly into your PC.(I did it with the adapter) In the folder containing TOTALNewbieasyInstallerPandorasmenu, run START.exe and follow exactly what it tells except Don't worry About the first Format as we already did that in a previous step. Type the Memory Sticks drive letter in and press Enter twice. Then Give the volume a label and press enter. I called It "Magic Mem" It then asks about formatting,press "y" and press enter. Then it says to take out the Memory stick and Stop USB connection. Do This. If You are using an adapter, stop the device then disconnect it from the adapter. Press Enter. Then Plug it Back in the Adapter or PSP (whichever you where using) If you are using your psp, switch usb mode back on. Press Enter. Then Choose 4 and press Enter, it will then proceed to copy files to the memory stick. If it asks you to write ABS then press y and enter(sometimes it won't). There we have it the magic memory stick is completed. Press enter to exit the program. The Moment of truth has arrived!!!!!!!!!! Put the Memory Stick In the PSP and then plug in the Battery. If all is good the Memory stick light will flicker(If you are using this on a Phat PSP, you will see a menu). Now press Square to make a dump of your nand. DO THIS BEFORE YOU INSTALL THE CUSTOM FIRMWARE!!!!!!!!!! YOU WILL NOT BE ABLE TO COPY THE NAND IF YOUR MEMORY STICK IS 64MB IN SIZE, AS THE NAND BACKUP IS 66MB AND THE FILES ON THE MEMORY STICK ARE 22MB. IF YOU DO TRY TO DUMP YOUR NAND ON A 64MB MEMORY STICK YOU WILL CORRUPT IT Warning: Spoilers inside! After the PSP has finished copying the nand, it will shut itself off. Take out the Memory Stick and Plug it into your PC and copy nand-dump.bin so you have it as a backup. Reinsert the memory stick and the battery, and once it is back on, press X. While the Firmware is installing, the lights will be flickering. When All the Lights turn off you can take out the battery, plug in the power cable, and when you turn it back on 3.71M33!!! Now go buy yourself another battery. NOTES: It didn't work straight away for me(with TOTALNewbieasyInstaller), so it may not work straight away for you(THIS IS WHY I RECOMMEND USING PSP GRADER). I had a period when only the green light of the battery would turn on, even though i had the Memory Stick inserted. To overcome this, just remake the Magic Memory Stick.(I had to about 5-6 times) FAQ My Firmware is version X.XX can I put it onto custom firmwre? Yes. Pandora's battery works with every version firmware so far. But it is yet to work on the psp 3000. Can I use my memory stick as a normal memory stick again after i have installed custom firmware? Yes Just format it in your psp's system settings menu. Can i use my battery as a normal battery again? Yes, but use anime_junkies method described above. Can I use a phat Pandora battery on a PSP Slim? Yes, phat batteries do work for Slim but you won't be able to use the battery cover. You cannot use a slim bat with a phat psp. Once I have installed the CFW, is there any way to get back to the OFW at some point? Yep. Just run Pandora's Battery with the Magic Memory stick again but this time press Circle, which will install Official Firmware. I will not help anyone to get these files and any requests for them will be ignored. I will try to help anyone with questions regarding the steps set out here via PM or below.
