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:

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

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

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