[REQUEST] Lenovo Yoga 2 13 (96CNxxWW) BIOS Unlock

[jerryxia]

Hello, there!

My original Intel 7260-N single band wireless card on my laptop stops to work recently. The card disconnect from the AP all in a sudden, I have to firstly disable the card in the windows device manager, and then then enable it. This drives me crazy. so I tried to replace the old card by dual-band ones. but you know, these cards are unfortunately all blacklisted.

Is it possible for you guys to release a mod for the latest 96CN29WW(v1.15) BIOS (http://support.lenovo.com/us/en/products...ook-lenovo)?

Because of I am a newbie in BIOS, I noticed that people always provide a BIOS scanning report and dump content of their BIOS flash chip in the attachment, which named "result.rar" typically in their request thread. can any one tell me how to make those kind of scanning report? and where to download those tools for the BIOS backup and upgrade? the linkages in their thread are all no longer accessible.

Here is my BIOS backup:

any advice will be a greatly appreciate.

Thanks for your kindly reply, BDMaster, here is the scanning result and full flash content:

please help to check whether it's possible to remove the whitelist? thanks.

according to the writing test result, it seems that I need an external SPI programmer to do the BIOS upgrade. Luckily I have a flash chip programmer in my office. then it's easy to handle the write protection issue.

Is the whitelist function removable in my BIOS? may I buy a 7260AC/7265AC module and provide you the hardware ID first?

You need to buy the tools to read and write your Eeprom Chip Firmware so look here :

Hi, friend, Thanks for you kindly reply, I have these hardware tools, already. and I know how to use these hardware tools to read and write a flash chip. My question is, I don't know how to modify the BIOS for a whitelist removal at the software layer. please teach me how to modify the BIOS, I mean the software part, or could you help removing the whitelist validate functions away, please?

Hi, BDMaster, the firmware is now available here:

I have encountered an over current protection issue yesterday, when I tried to read the flash chip online by my previous SPI programmer. then I have to buy another one, a well-known "CH341A" chip based USB programmer, without any limitation, you know, it's cheaper, but more reliable.

I replied in PM !
