Thanks for the clarification.
As I said, the 16 in 25Q16 denotes this is the smaller chip with just 2 MB, so NOT this BIOS chip.
Go for the 25Q128, this is your 16 MB BIOS chip ......

Oof, I though, the ME region in the downloaded bios update should already be clean.
Is there a guide somewhere on how to do this process using the FIT tool?Leave a comment:

Hey guys!
You can call me Nebukad
I have studied in germany to receive a Masters Degree in Electronic Engineering and worked in that field for almost 6 years now.
For many years, I have also been fixing laptops and all sorts of other electronics, and am now pivoting more towards that kind of work.
I know my way around a soldering iron, a Flash-Programmer and a Hex-Editor, but since BIOS's seem to get more and more complicated, I will be sure to stick around to get some more knowledge about this topic, while also sharing some of my own.
Cheers...Leave a comment:

First things first:
The first IC you tried is definitely not the BIOS chip, but most likely a temperature or voltage monitoring ICs
BIOS-(Flash-)Chips can be identified by their marking starting with 25... (or in some cases 24 ...).
Note that 24...-Type ICs will have 16 pins, so you need the bigger area on your programmer, but 99% of the times, you will encounter 25...-Type chips.
So as you can now see, the two chips you found (U365 and U366) are indeed 25-Type flash ICs. So you're on the right track.
The next number in the marking (25Q[B]128 [/B]and...Leave a comment:

Thanks again for taking the time! Much appreciated!
I tried myself to by create the cleaned file by:
- copying the BIOS region (220h --> 100021Fh) to 1000000h --> 1FFFFFFh and
- copying the ME region (1000240h --> end) to 1000h --> FFFFFFh
My file now has the correct size and looks OK, but it's different to your file in ME and Descriptor region.
I assume, your file was created from a different dump, is that correct?
Would my file still work or did I miss something?...Leave a comment:

Thank you for providing the file!
Is it possible to explain to me, how to produce this file myself, so next time I don't have to bother you again?Leave a comment:

I was hoping for someone to explain to me, what I am missing.
But sure, here is the serial number: 5CD8444NCWLeave a comment:

Hi there!
I am working on an HP X360 1030 G3, that will not post (black screen, fans on high speed).
As a first step, I wanted to reflash the BIOS.
I downloaded the most recent BIOS from HP and dumped the content of the Flash.
The BIOS Chip is 32MB. The downloaded file is about 23MB.
According to the UEFI Tool, the dump consists of descriptor+ME (16 MB) and BIOS (16 MB).
So I would like to replace the BIOS part with the downloaded file, but it's obviously too big. According to UEFI tool, it contains nothing else but the UEFI region, but I suspect,...Leave a comment:

I registered, just to thank you!
That was exactly the Problem with my set. Would have never gone that far to desolder that pain-in-the-arse tin shield, to get to the Cap, if you would not have provided this information. Another TV saved from the yunk-yard.
Thanks again!
