[HELP] Lenovo Y700-15ISK BIOS corrupted

[ToxicCow19]

I moved this to my own thread @Lost_N_BIOS . Here’s the original info:

Hi! I had a problem with the BIOS on my laptop, it’s a Lenovo Y700-15ISK. It got corrupted after changing the secure boot settings and now it’s stuck in a boot loop.

I watched a video on reflashing UEFI BIOS and apparently you have to extract the motherboard’s serial number, UUID, and MAC address from the old image and then inject them into the new image. The problem is that in the video they use the FD44Editor for Asus boards, but obviously my board isn’t Asus.

My BIOS is an InsydeH2O UEFI BIOS. Is there a tool to extract and edit such numbers or can I do it with a normal hex editor? And if so, what should I look for when using a hex editor?

And second question, my BIOS update file comes as an .exe. How can I extract the bin or rom or fd file from there?

I’m still waiting for my ch341a to arrive, so I want to learn as much as I can in the meantime.

Thank you!
