Hey, i tried your file, but it doesnt work for me it blinks 2 white and 2 amber.
Maybe the bios chip is defective?

I've desoldered the chip so many times and rewritten a new BIOS dump, but every time it flashes 2 white and 2 amber.
Even with Dell Recovery I cannot restore the BIOS, it reads the USB stick but that doesnt lead to anything.

Could it be due to the 1mb or 4mb bios dump?...

It doesn't work for me.
When I created the BIOS dump, I didn't check whether it was ok and maybe it was faulty? I dont know.

I've tried various BIOS dumps from this thread, but the laptop comes with 3 white and 4 yellow lights and Dell Recovery BIOS_IMG.rcv doesn't work for me either.

I've attached my other two BIOS files. Can I clean those as well?
Is there a way to write to the chip with the clip? I have to unsolder and write to it every time. Using the clip, I always get an error saying it's protected. I use AsProgrammer or NeoProgrammer....

Can you please clean my BIOS Dump :-)
