Lenovo B5400 bios recovery

[compufreek]

Hello !
I have tried to update my bios to newest version and in the middle of the bios update PC rebooted (saw online that i was not the only one). i have tried everything (battery draining AC removing CMOS battery out for 10 minutes )and nothing helps. Now i am searching the internet to find out how to recover my bios. I found this tool wincris which is suposedly useful for lenovo but i cant make the wph file as the bios file is .fl1 and to get the image out i need some exe file .... atleast that is what tutorial says ....has annyone tried to recover the bios on this laptop yet or maybe simmilar laptop?

the laptop is out of waranty.

anny help would be greatly apreciated!

i apologize for my bad grammar and if i have posted in the rong forum section.

Lenovo is the worst Recovery Bios I know so I can suggest You to get the Tools
(SPI PGM + Clip) and make a Full Dump Firmware !
Then upload It here and I will rebuild It for You !
Look here :

It's cheaper may be $.30,00 for all !
Let me know
Regards

P.S. your laptop has this Eeprom Chip
