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

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...

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 :(
