Toshiba C660D-13Q BIOS

[Orfeas]

Hello

I bricked my laptop (using the BIOS provided by Toshiba ) and desperately need help.

Laptop details:
Toshiba Satellite C660D-13Q
Part No: PSC1YE-00G009GE
Serial No: 3B55884K

Motherboard details:
Hannstar J MV-4 94V-0 1052
PWWBE LA-6849P Rev 1.0 2010-11-25

I tried to reflash it with a CH341A programmer but without success... I am not sure if I have the correct BIOS...

I believe I am flashing the correct chip, which is labelled U13. The chip details are:

TS25L020A -VCF 1103W 108F34 (Terra Semiconductor, 256KB, 3Volt, SPI)

If someone could send me the correct BIOS, and also recommend me a software for my CH341A device (it doesn't recognise the chip), I would very much appreciate it. If that would be of any help, there is a sticker on the motherboard that says "PWWBE v1.40 BIOS U13 CB5".

Thanks

The bios for this should be 2MB .The extracted update from tosh and all bios dumps around the net are 2MB. The schematic does show a 256Kb chip, which is wrong.So you need to source a 2MB chip first .

Thanks a lot for your reply.

There is another chip, U55, which actually is 2MB (see attached image). It is labelled:

Winbond 25Q16BVSIG 1103

Please note also the white sticker above the chip that says:

PWWBE v1.40 BIOS U13 CB75

I was trying to flash the laptop with v1.60 from Toshiba, so since that didn't work, I guess I must use V1.40

I was just wondering, in the official Toshiba v1.60 update (I managed to extract with the UniExtract utility), there are 2 folders, DIS and UMA and each one has 2 files: BIOS.rom (2MB) and EC.rom (128KB). Which file is for which chip?

Post the 25Q16BVSIG backup here in a zip or rar .
