Still IDXFFFFFFFFF error on TA-095v2

[stevealexanderames]

A friend of mine just bought a PSP 3004 9g with motherboard TA-095v2 and tried to downgrade his PSP (for the very first time, obviously) to firmware 6.20, but ChronoSwitch Downgrader keeps showing Error IDXFFFFFFFFF trying from fiirmware 6.39 or 6.60.

I thought that this error happened on the second downgrade with v2 MoBos; any way to fix it?

Nope, we have to wait for new version (5.1 probably)
I have the same problem 95v2,9g, 6.39 factory installed and idxfff error when attempting to downgrade to 6.20 (tried from 6.60 and 6.39)

what about this?

Ok. So i want to try compiling all of the Davee & some1 downgrader source codes.Its all fine and working good. But when i run it on my psp and it says:
loading SCE updater failed = 0x80020149 . am i doing it wrong or am i need something else?

hah... I yesterday asked some1...
Change SceModule struct in psploadcore.h:

Code: Select all

//© Davee | some1
typedef struct SceModule

And.. you can test edited downgrader. Maybe it worked on TA-095v2.
