I have a PSP-1000CW boxcode H, TA-081, now at 2.60. And several PSP-1004 boxcode C (TA-079) and F (all TA-082's).

I still have no means of unbricking. If you say it is safe, then I will be glad to test!

How did you test it? How many bricks did you make (and unbrick)?

Hey 0okm, when I first saw this exploit I immediately thought about you and DHT.
I posted my ideas about what might be possible in dcemu psp forums:
I posted the idea in that thread, post #27

Some people there told me flash0 access was not possible for some reason.
Thanks for confirming it is possible!

Thanks to you, us 1.00/1.50 users may be able to choose any firmware up to 2.60 and be able to return to 1.00/1.50 later!

Can't wait for FW1.00 DHT v1.2! :P

i test 10pcs psp
reflash them to FW1.00
8pcs OK
2pcs have error
but never mind

Some people there told me flash0 access was not possible for some reason.

now on FW2.60 you can access "flash0" or "Nand Flash"

Hi 0okm,
with your multi firmware module
can you keep the PSP at 1.50 and run the 2.60 and 2.71 EBOOT against the external multi firmware module flash device?

I suspect that Sony Eboot cannot program device other than SAMSUNG MCP with its specific flash id registers?

you can
one is FW1.50
another FW2.71

K5E5658HCM's ID same as K9F5608Uxx

:D Great!

I have ordered a UP module and I will try to find out if they can do this, too. ETA unknown.

I was afraid that Sony might blacklist non-MCP flash id's in BOOT time in IPL's in next firmwares like FW 3.00 (GPS support ;P )

UP does not state that it is possible to run Sony EBOOT update against their flash device. UP does not say that it is impossible, either. On production devices the flash device markings are made unreadable.

I have tested something:
Start with 1000-H (TA081), update to EU 2.60, it is still JP X-0 buttons.

Downdated with DAX-SXT 0.5beta with 1.50 EBOOT and PSP1004-F (TA081) -> 1.50 as donater.

Then I have 1000-1.50 FW but still JP X-0 buttons.

Use PSP-set 0.9 from www.psp-arena.de and change X-O. Now I have US X-O buttons.

I update to EU 2.00. Still US X-O buttons.

I update to EU 2.60. Still US X-O buttons.

I downdate again to EU 1.50. I have JP style X-O buttons again! ;P

The button settings are probably lost when recreating the settings after reboot to 1.50, the blue screen in all languages, press 0 to recreate.

If I downgrade from 2.00 to 1.50 I have the same blue screen and also the JP X-0 buttons arrive again!

When downdating with your flasher do you let the PSP recreate that settings table too?
