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...

Does anyone have the BIOS of this machine? AAM00 LA-C361P Rev 1.0 (a00)

Today a colleague asked me for help because he was "repairing" his laptop because it wouldn't turn on (it wouldn't turn on because it had some short capacitors and well that's another story). He confessed to me that he was following some tutorials and started to move to three integrated that brings this machine thinking it was the bios.
- IC1 (Bios): MX25L12873F
- IC2 : 25Q80DVSIG
-IC3 : 25Q32

The truth is that I don't know what he did to them but the laptop actually turns on but it seems that it doesn't have a bios. (it turns on the power light but turns off almost instantly and that's it)

I tried to load a Bios that I found here in the forum but it still does not work, so I do not know if he delete or damage the information of the 3 IC....

Re: DELL XPS 9550 bios dumps

Mine is also dell xps 15 9550 but with different problem:
D + power goes screen test
sometimes is gives me dell logo for few seconds than screen goes off.
if i power it off then on, no logo will appear..i must wait many minutes to get the logo again, i cannot enter bios.
I tried bios posted by SMDFlea post #23 , but all i got is black screen with fans spin for few seconds only, i waited half an hour with no success...
this is my bios file:
service tag(S/N):FKVMJ2
