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

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
