hi all here it's just a exemple how kill five psp in 1 day :p . Never use this code i've tested all possibility today at downgrade the psp and i've win's 5 bricks two psp 1.0 ("updated to 1.50 for test ") and three psp 1.5 .

1 : if you change the loadexec.prx and the pspcnf_xxx.txt your psp never boot anything from the ms so you cant updated to 1.51 or 1.52 for restore your flash you is f**ck*d .

2 : if you change all files from flash0:/ your psp never boot only you see the green led 10 second and shutdown .

3 : if you replace the flash0:/ and flash1:/ it's same your psp turn on 10 second and shutdown .

if you whant downgrade for win an brick you can continue to play with your lflash .

If you had studied this board more carefully, you would have known that simply copying files over won't work.

It has also been revealed that lflash: does not access the entire 32MB of flash memory, so that won't work either.

Let's hope the sceNand driver work will pay off, see the beginning of this thread:

sceNandReadPages
sceNandWritePages

Perhaps sceNandReadPages (once set up correctly, see the other functions) is able to read the whole firmware. Once I get the toolchain set up correctly and a larger memstick, I'll try to get it working (but I'm staying away from WritePages though!).

Only people who:
1. Can recover from bad flashes
or
2. have many spare psp's to brick

Should be experimenting with flash.

I only know of one or two people in category number one.
I really don't know anyone in category 2. Well, I know of one person now. Sorry about your misfortunate. :(

I may or may not have stumbled onto something;

http://www.snsys.com/PSP/ProDG.htm

Under "Target Manager" it says:

# Integrated, safe Kernel flashing

Update any "PSP�" development tools from a single location. Removes the need for an additional Linux PC.

If they are talking about the dev kit, and without their product a Linux box is required to flash the firmware (it would seem logical devkit PSPs also get firmware updates, and for regression testing, downgrades). Perhaps there is hope...

Sorry about your bricked PSP, Yoshihiro :(

Here is how to setup PSP to enable recovering bad flash. A little hard way though. ;)

If you have direct hardware access to flash chip, it is possible to reflash.
You will need to interrupt physically the lines between CPU chip and MCP memory chip if you want to keep PSP running.

- determine which pattern is flash signal line, which is what, and their protocol
- cut off the lines and pull out the signals of both end
- make some hardware to enable access

By this way, you can reflash on-the-fly. The problem is the tapped PSP is not good for playing games, but great for experiments.

I'll buy one or more of the bricks if anyone is willing to sell. Let me know.

I myself had my psp bricked too, sort of. I used an earlier version of the code that only copied 4 or so files, and none informed me that the paths were hardcoded.

Since there was no error checking to find out if the source file is there, it just does O_CREAT on the targert (clears it blank for writing) then the program when into and infinite loop. That first target file was "loadexec.prx", which junked the psp from starting any software :(

Brad, I was more or less expecting someone like you to post about store-swaps.

We do not tolerate discussion of this unethical action on the boards. It is indefensible, and there is no arguing. Consider yourself, as well as anyone else reading this thread, warned. Continued suggestions or implying or defense of this activity will result in bans.

No, it's to reflash a devkit....which differs from a retail PSP.

Besides that you'd need a Sony approved concept, and give Sony the idea that you can complete that concept in a way it won't hurt the image of the PSP experience, before you get the hardware, which is not included with the SDK, and both come at a healthy price.
