First post here so hopefully I've got everything right.
My friend just got a lenovo yoga 2 11 with a core i3 4012Y to replace his surface pro 5 due to a dead soldered SSD. There are different models of this yoga, like the one with a pentium, but the one in this thread is the 20428 model with the i3 4012Y.
I own an identical motherboard in my collection of stuff, and have decided to use mine for playing around with so my friend's unit isn't down. Testing the board will require swapping it with the one in my mom's yoga though.
I've desoldered the BIOS chip and dumped its contents, available here:
YOGA.2.11.20428.4012Y.BIN (Size: 8 MB / Downloads: 14)
Lenovo's BIOS update for it can be found here:
isflash.zip (Size: 2.87 MB / Downloads: 9)
The original wifi adapter has an ID of PCI\VEN_168C&DEV_0036&SUBSYS_302617AA&REV_01
I do not know if the board I dumped was running the same version as the provided update however. Let me know if it needs to be, and I'll put this board in my mom's laptop chassis, update the BIOS, and dump it again.
I plan to put the image back on the notebook the same way I got it off if I can, using my CH341A programmer and good ol' lead based solder. Much easier than dicking around with software.
I'm quite curious as to how this mod is performed, as my mom has the pentium version of this laptop and really does need a decent wifi card, and would be awesome if I could perform the mod myself.
Thanks!
