Success SoftDown FW2.50 TA-082 to FW1.00/1.50

Had found a method SoftDown TA-082's FW2.50 PSP to FW1.00/1.50
But the method is quite complex, SoftDown a TA-082's PSP need about 45min

1. Use software Read Data From TA-082's NandFlash & DDR DRam
2. Analyzes the Data than make a "FW1.00/1.50 NandFlash img" that can Boot on TA-082
3. Use software Write that "FW1.00/1.50 NandFlash img" to TA-082

maybe late i will make a software to let "FW2.50 TA-082" user to dump "NandFlash & DDR DRam" data to me
than i can make the "FW1.00/1.50 NandFlash img" to help them SoftDown their TA-082 :P

UPDATE1!

NOTE :
1. each TA-082 PSP need different "NandFlash img"
　CAN'T use this "NandFlash img" to OTHER PSP
　That will Bricked the PSP !!
　so SoftDown each TA-082 PSP DATA need each 45min !!

2. if your FW2.60 TA-082 PSP is Update from FW2.50
　this method can work for your PSP

3. this method not work for Factory FW2.60 TA-082 PSP
　maybe later it can :P

UPDATE2!

UPDATE3!
0okm has made a FAQ, here it is:

Quote:

Will I be able to update to 2.0 and then down to 1.5 again to get a clean firmware? (whats the difference between clean and unclean 1.5 anyway?)

no
just like PSP-1007 can't run FW1.50 UpDate EBOOT.PBP
TA-082 can't run FW1.50 - FW2.50 UpDate EBOOT.PBP

and i don't want to released the "clean FW1.50 image file"(that is illegal !!)
so i need time to make a "Write software" that can generate "clean FW1.50" :P

Quote:

Will I be able to upgrade to 3.0 when ps1 emulator comes out?

yes
TA-082 can run FW2.60/FW2.70/FW2.71/FW2.80.... UpDate EBOOT.PBP

Quote:

How do you intend to manually downgrade hundreds of psp if it takes 45 minutes to do each one?

i think each day i can help zero to five TA-082 user to softdown :P

He'll probably release an app thatll create the psp specific .img for each user

hope that they'll make an app that checks what mobo you ahve and does everything correctly, so that you dont have to bother about anything. it'd make me possibly downgrade.

Awesome! Time for another big "In your face, Sony!"

In your face, Sony!

this is kool.....i dont get it why could we not downgrade them before. i know its a different mother board and like a different current but ..........

CoBrA9891 · #10 (**permalink**) 08-21-2006, 03:59 PM

well, im guessing sony changes the way the ta-082 motherboards boot and that only 2.0+ would be compatable with that boot sequence or something like that...
