DELL XPS 9550 bios dumps

[peste]

Hi,

TPM is not find on my xps 9550, I tried to reset bios to factory rollback to old version (and factory reset) ...
It looks like you patch some bios here, sorry for the noob question but can I apply the roms found here ? Flashing from usb key says they are invalid.

Regards

you can use the bios found here but like this..

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

don't forget to make a copy of the original bios before writing the bios chip...

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.

Hello try this file ...

Hello try this file ...

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?
