IDXFFFFFFFF error downgrading from 6.60 to 6.20

[cameraguy256]

Set your CPU CLOCK GAME to 222/111 or Default to work.

I did that already and nothing has changed, it still crashes...

i have a 0x00002A00 then i tried cronoswitch v5 then it gives me a idxfffffff error.
then i used 6.20 pre -downgrader. then it gives me some error messages but i think it was installed successfully.
then afterwards i used cronoswitch downgrader again the error idxffffff error is gone but there is now a error SGT90000001

Did you use this 6.20Downgrader after using pre-downgrader [FIXED].

please try again.

I can't get the sleep mode fix to work either.

I've tried with CPU CLOCK GAME on 222/111 and Default and my PSP crashes either way after downgrading to 6.20 on TA-095v2 motherboard...

[stingray1059]

the sleep mode fix sometimes work then sometimes it does not work especially when running ps1 games.

can i revert it back to 6.60 official?

Try this... http://lolhax.org/davee/psp/chronoswitch/version_5f.rar

Hmm , I have the same issue, and the file that you gave did not help, the error still persists... :\

Use this.
PSPident 0.75
to check you FUSE CFG. if it is 0x00002A00
you can downgrader using this 6.20 Downgrader

and If your FuseCFG 0×00003300, 0x00003B00 or other
must use this 6.20 Pre-downgrader before the 6.20 downgrader
here's your OFW Firmware 6.20
and this is the 6.20 Sleepfix Plugin to fix your sleep mode bug.

goodluck!

I have the same problem but the X does not work to start the Pre-6.20 downgrade

how should i use it ?

Thanks
