Lenovo Yoga 700-14ISK Bios Crisis Recovery

[phil-lenovo]

I have a Yoga 700-14ISK laptop where the BIOS has been updated..
 
Since the update the laptop now does not turn on, the screen is completely blank. The keyboard does light up, fans are running and there are a series of beeps. 2 Short and then three longer ones, three more longer ones and then a single beep.
 
Does anyone know if the BIOS can be updated again in this state, somethings clearly gone wrong in the last update. I've seen in other posts that a USB can be loaded with the BIOS file and booted from blind to do the update. Can anyone give any pointers on how to extract the BIOS file from the installer package dbcn27ww.exe.

I basically want to perform a crisis recovery if it is possible to do so?
 
Any help would be massively appreciated.

Hi
Phoenix bios...the crisis recovery procedure does not work
You need a SPI-programmer+SOIC8 clip only

Hi
Thank you for the response. 

Understood, I will take that approach.

I will still need to get hold of the BIOS binary file...and I am struggling to extract it from dbcn27ww.exe using innoextract.

Any ideas on the best way to extract the BIOS file from the installer package?

Thank you Dudu, I've managed to read from the chip, and I've sent it over to you.
