Hi all.
I have a bad story for my PS3 2508A DATA CODE 1A (OFW 4.31 , 3.56 on factory)

1.make good dump via E3 flasher.
2.try make downgrade dump and write it in my PS3, but it not work for 4.31
3.write back my original dupm and PS3 working fine!

BAD STORY
4.I make downgrade dump for 4.30 and write via E3 flasher.
5.rename down425to355.pup to PS3UPDAT.PUP and make update in recovery mode! (my mistake)
6.PS3 is breaked!
7.Now i write good original dump but PS3 is not working!
8.Now after write dump for downgrade for 4.30 I have request 4.40 or high FW. Installation begin only on down425to355.pup(after rename ofcouse) file, other PUPs not working! I think down425to355.pup maked changes for SYSCON.

Any body know how I can fix it?

u do know that your ps3 can't be downgrade to 3.55 .

[ZeroCold]

now, I know it
but I need recover on 4.31 or 4.30 if it impossible

[ZeroCold]

any body know how I can rebuild down425to355.pup to down425to356.pup ?
may be in this case ps3 is begin working.

or can be there is other way? example SPI or JTAG reprogramming or reset SYSCON

Reflash original OFW dump, then install OFW 4.31 from the recovery menu.

I do it many times, but it not working now.
I think down425to355.pup reprogramming SYSCON.

Your original dump is not working, because the downgrade PUP was installed to your hdd.
That is why you need to flash your original dump. Then enter the recovery menu, and choose option 6. To reinstall the correct firmware.
