[Tutorial] Downgrading 2.80 PSP TA-82-TA-86
You Do NOT Need GTA LCS!!!
What we need:
2.80 Hen
TA-82 Downgrading Files
1.5 Update Eboot
Plug your USB cord into the computer and into your PSP
Step 1: Open the 2.80 Hen files you downloaded and cope the folder in the drive your psp is (Example: G: ). If you dont get a folder and a lot of files then extract the files to your desktop and they will change into a folder.
Open the TA-82 Downgrader file you downloaded and copy the folder in the G: or whatever your drive is for your PSP. Do the same thing if you see a lot of files.
Rename the 1.5 update eboot to UPDATE.PBP. Then copy them to /psp/game/UPDATE
2. On your PSP go to the Photo Menu and then enter the HEN 280 folder.
If your PSP freezes just keep trying to open HEN. It took my friends about 40 times until his actually worked.
Red - The files couldn't be read. Try again
Blue - The files were successfully read
4. Execute the 2.80 idstorage changer.
5.Now execute "Update X.YX"
If it worked restart your psp and it will give you a blue screen with a lot of languages on it. just press "O".
Enjoy! You should know have a 1.50 firmware!
