IdeaPad Flex 5 14ABR8

Serial Number PW06Y8HK
Machine Type Model: 82XX003XCF
GTIN: 196803904260
Motherboard: MB W 82XX WIN R77730U UMA 16G
Motherboard Part Number 5B21J35232

The Lenovo BIOS utility corrupted the BIOS chip, system will not boot a device, but I can view/edit BIOS settings booting with Novo. When reading the BIOS chip the corruption seemed to start around 4.1MB.

If I could get a working image to flash onto the BIOS chip part no W25Q64JW that would be fantastic!

Alright, thank you. I copied the given DMI and Windows key bytes from my backup onto the supplied image, but after flashing I'm getting the Caps Lock and Escape keys with an LED, power LED flashes. The only "success" I've have is Caps Lock only being on from flashing my backup, anything else I've tried is both Caps Lock and Escape.

I'm using a CH341A programmer with the 1.8V adapter, I can flash and verify using ASProgrammer over SPI on IC W25Q128FW_1.8V.

Any other ideas what I could try? I've spent an incredible amount time on this and at this point I'm at a loss.

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

.here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

That's a good tip, I'll give that a go. Thanks for the advice!
