Hi all,
My first post here, so first of all many thanks for such a great forum.
I just bought a Yoga 2 13 from my niece as she never really used it due to its slow wifi connection and shortly after a dead hard drive. So I managed to resurrect it with a new SSD and then found out that the wifi card could also be upgraded. So I bought an Intel 7260 AC Wifi+Bluetooth4.0 WLAN card that was taken from a Lenovo ThinkPad X240. But then I read about the whitelist in the BIOS. I thought I might be ok seeing as this card was already from a Lenovo laptop, so I installed it, accidentally when the Yoga 2 13 was in sleep mode, and when I woke up the laptop, the new wifi card was recognised by Windows 8.1 and I was able to connect to my router. So I thought I might have got lucky, but just to check I restarted the laptop and...got the "Unauthorised Wireless network card" message.
So after searching more about this I found this forum and a useful doc guide called "Removing whitelist check in T430 BIOS" together with several other threads. I was trying to figure out how to do this myself but have relented due to my lack of programming skill and dont want to mess things up.
I also tried to read the BIOS chip based on the useful posts by exetico at
https://www.bios-mods.com/forum/Thread-R...4#pid83254
Since I already have a Minipro TL866 programmer and SOIC8 test clip, so I tried using that to read the BIOS chip on my Yoga 2 13 which is a Winbond 25Q64FV chip, but the TL866 software was unable to detect the chip, and I couldnt get any results with that method. I will probably just order the same programmer as recommended by exetico and others and see if that works, but not sure why I wasnt able to read directly from the chip with the test clip. I made sure the pin 1 was correct on the programmer and the clip etc. Also tried with power and battery disconnected from the motherboard, but then read somewhere that said power should be supplied to VCC, which should be pin 8 according to the winbond W25Q64FV datasheet. Anyway I will try again and if not will order that CH341A Programmer
Anyway, I then read that I could dump the BIOS using a program called NEW_BACKUP_FPTs.exe.
So after I removed the new wifi Intel 7260 wifi card and putting back the original wifi card I restarted the Yoga 2 13 and booted into Windows 8.1, then from command prompt (as Admin) I was able to successfully dump the BIOS using the command fptw.exe -d biosbackup.bin -bios
I have now attached that here and am hoping that this is correct. If so, please could you remove the Wireless whitelist and also unlock the BIOS menu. Thanks very much.
