Hello,
The HP PC I own no longer starts after an official update ...
The board is DA0R33MB6D0 REV : D
I launched the installation by Windows and I now find myself with a black screen, orange WiFi led and that's it. I tried to unplug the battery, do the key combination etc, nothing helps.
I have a CH341A programmer but I don't know how to get a clean file.
Can you help me please?
Thank you in advance !
Jonathan

PS : Here is a link with my dump file from actual state : https://www.dropbox.com/s/60cxaqpfl9j9jc9/DumpHP3.rar?dl=0
and the link of the original firmware that i try to flash : https://ftp.hp.com/pub/softpaq/sp77501-78000/sp77532.exe

Definitely not a valid backup! What chip is this? And try to read it until you get at least two a 100% identical reads which give a structur in UEFIToolNE!

---

If the programmer does read the chip properly they're not similar, they're identical bit for bit. And if you can't read a chip properly, you can't write it properly.....

This dump looks very much like a bad sitting soic-clip or an incompatible program. And never seen a bricked update process looking like this dump does.

Which chip, which software?

I don't understand. My programmer read the chip properly, it detect the MX25L6406 if my memory is good (the laptop is at work) and i can read it many times i want without any error.
I use the original software (CH341A programmer) and a version from this website : https://khandishnetwork.com/dl/ch341a-ne...ted-15-10-2021/

Results are similar and if i compare files on an hexeditor software, all are strictly identicals.

Well, the chip you mention has 64Mbit, 8MByte, but your dump has more than 8.8 MB. In addition the size of a complete bios image I can extract from the update file you linked as appropiate for you machine is 4MB (32Mbit) which is quite normal for such a notebook.

- You got the wrong chip?

- You didn't read it properly- how were you able to read 8.8 MB from a 8 MB chip?

(The data in the dump do look far too structured to be corrupt, it's only hex- values with '.' and ':' as dividing signs?)

I'm not sure about the chipset reference. I don't have the board with me. I can add valids informations tomorrow at work.
Can you help me to create a valid dump please ?
Thank you.

Congratulations, you got a bios dump!

Left side stock bios, right side bricked dump- search the difference...



HP fix gives you possibility to extract, run InsydeFlash=> copy file. You find a 5120 kB file, which has 'something' first 1.2 MB, 4 last MB look like a stock bios.

Try attached file, unpack, flash it, read the chip again in new process, save in different file. Original file and dump have to be a 100% identical!

(File is stock bios from update with own data transfered, empty/clean NVRAM. it normally should work.)

Hello,

Sorry for being late, I got sick and couldn't take care of the PC.

The bios seems to be ok, thank you very much but I still have a problem with the image:

I have a screen with a simple backlight only. I tested by connecting an external screen and there, I have the HP image with access to Bios.
So I changed the connection cable between the screen and the motherboard but still the same.

What do you think ?

Thank you very much again.

Jonathan
