I have now flashed the W25R256JV chip with my BIOS dump. When I plug in the power adapter, sometimes the power LED lights up, sometimes it doesn't. When I press the power button, the keyboard lights up, the fan starts spinning, but then everything shuts down again and the white power LED keeps blinking continuously. The screen remains completely black.

Could someone please help me with this?...

Oh, thank you very much! So it has to work with the W25R256JV, right? Thanks a lot. What about the BIOS dump – is the program able to handle it?...

The original BIOS chip was a GD25R256EYIG. I’ve already tested the W25Q256JV, and I plan to try the W25R256JVEQ next. Unfortunately, I haven’t been able to source the original chip...

If anyone has a moment, I would really appreciate it if you could take a quick look at my BIOS file — the system doesn't boot anymore, and I'm stuck. Your support would mean a lot!

Thanks in advance for your help!...

Hi friends, after my BIOS got corrupted, I replaced the chip and successfully flashed a new BIOS dump. However, I keep encountering errors when I try to boot the system.

Here are the details of my laptop:
Service Tag: 2QDBYD3
CPU: Intel Core i7-11850H
Model: Dell Precision 7560
Mainboard: LA-K621P

I found a BIOS dump online, but I’m not sure if it’s compatible with my EC chip, which is still the original one from the laptop. Could you please check whether the BIOS and EC dumps I have are compatible with each other?...
