How to downgrade, install CFW on ANY PSP using Datel TOOL and TotalNewbieEasyInstaller:
Intro:
As an alternative to my other tutorial on installing CFW using UPMS, this tutorial will show you how to flash your PSP with CFW using a previously purchased Datel TOOL battery and Windows based program called TotalNewbieEasyInstaller.
Disclaimer: I don't have Vista OS, but I have read that the important part of this guide(IPL writing) doesn't work on Vista.
What you'll need:
- Your PSP, either original or Slim PSP.
- Memory Stick Pro Duo ranging in size from 128MB (minimum) to 4GB (maximum)
What to do:
1. Download the TotalNewbieEasyInstaller from QJ.net website
here.
2. Extract the contents of the zip package to your desktop.
3. Run the "START.EXE" application.
4. Connect PSP to your PC using USB cable. (Take note of the letter your PC assigns to the PSP MS).
5. Press ENTER to format your PSP. Depending on the size of MS being used, this can take up to 5 minutes to complete.
6. Press ENTER to set the drive label and then Y at the next prompt to format MS again.
7. With USB connection active, remove MS from PSP, then disable USB connection by pressing "O". Press ENTER to continue to next step.
8. Insert MS card into PSP and wait till orange access light stops flashing and then activate USB connection. Press ENTER to continue to next step.
9. A menu will appear with 4 installation options. Choose "4. Universal Unbricker: 3.71 M33 Installer.
10. When installation has finished, the IPL loader screen will appear. Press "Y" to install.
11. Then press ENTER and ENTER to close the program.
How to use:
1. Turn off PSP and remove AC power supply.
2. Insert Datel TOOL battery.
3. DC V3 should load up giving option to flash to 3.71 M33, flash Sony 3.71FW or backup NAND.
4. Backup NAND with square [ ] and it will write NAND to your MS, you will need 32MB (original PSP) or 64MB (Slim PSP) of free space for this. Your PSP will power off after this.
5. Remove and insert Datel TOOL battery again and this time choose X to install 3.71 M33 CFW.
Save nanddump.bin in root of MS to your PC when you are finished for safe keeping, incase you brick your PSP one day.
