Talk:SKU Models

Seems this SKU has had 2 different motherboard releases:

• CECH-250.A - JTP-001 - serial : 1-882-481-31
• CECH-250.B - JTP-001 - serial : 1-882-481-31

• CECH-250.A - JSD-001 - added by User:MikeM64 - serial: 1-882-770-31
• CECH-250.B - JSD-001 - added by User:MikeM64 - serial: 1-882-770-31

remark: MikeM64 : CECH-2501A with JSD-001 board, came prefactory with 3.40, which is also the lowest downgradeable firmware

Raw Model Data from my JSD-001 (CECH-2501A): 0x00, 0x01, 0x00, 0x84, 0x00, 0x08, 0x00, 0x05

QA doesn't give more downgradeability compared to JIG / Factory/Service Mode

dospiedra	i can downgrade with jig to 1.00 max
dospiedra	on 60 gb retro only , on my fat 80gb only to 2.30

rms	in my case 1.97
rms	cechg01

eussNL	dospiedra: what model whas that FAT 80GB ? CECHE/K/L/M ?
dospiedra	no idea, was assembled piece by piece and the shell model does not match the plate
dospiedra	sure is 16mb nor
dospiedra	and sata drive
eussNL	that would make it K/L/M
dospiedra	not 90nm
eussNL	all 3 are 65nm
dospiedra	I have no idea of exact model is
eussNL	K = DIA-002 board, L or M is VER-001 board
dospiedra	001 board
dospiedra	I am not sure
eussNL	you could run rms' infotool on it, to make sure, but I am not asking you to go for that trouble for me
dospiedra	rms later try to run it right now I'm busy, but I promise to give the exact model in few hours

dospiedra	hi , my ps3 model isCECHL04

ofc it doesn't, since there are no drivers for the newer system components in older firmware versions ;)
