Hello, Can anybody help with how to recover DMI and Windows Key from HP 14-DQ1004LA Bios

[abel2b]

Can someone teach me how to edit New *.bin with DMI and Windows Keys from broken bios.
where should I look (OFFSET) in old dump?
What must be copied to make new functional bios?
MY machine is:
HP 14-DQ1004LA
S.N: 5CD0080M17

Background: Tea was spilled on my notebook accidently I imediatly, turned off, unplugged and opened to disconnect battery, I cleaned everything thoroughly, I checked all power supply coils for shorts and all good, except Vcore coil ohms at 0.1 ohms, but I searched around and it seems it is ok. I powered up the board , and all voltages seem fine (5V,3.3V,1.8V,1.2V..) except Vcore not present but could be because of other error...

the notebook charges fine but when I press power button, caps lock LED is blinking 5 long, 3 short repeatedly and no video or post... that is why I would like to reflash BIOs just in case... I have tools to do so...!

I can download working bios around the internet, but I would like to learn to make new bios, clean ME etc.. myself

Attached is New copy of Bios fresh from website update

The block from 480000-4810FF, don't forget the "Build ID" and "Feature Byte" (starts with 3K....., it's also inside the back cover on a sticker) which is below a bunch of FF FF on your model
Example from a random HP 14-dq0xxx BIOS i found, the offsets are different but the length is same, as yours is a 14-dq1xxx

No need for the secure boot keys, the default keys from MS will get restored (i think)

On 2. select from the offset you find the Windows key until you get past "MPMLock" found after the Windows key, or it will say "Manufacture Programming Mode is in Unlock Mode" when you power on the laptop, on the HP 14-dq0xxx the Win key starts at 76D000, MPMLock is found at 76E000

The offsets vary between models, you need to search with hex editor
Start with searching the S/N on your original dump, once you find it copy the whole block until you see FFFF....
Example: This is from an HP 14-dk1003dx (AMD), with an example serial of 5CG12345NM (the model in BIOS shows as "HP Laptop 14-dk1xxx")
It starts at 283000 and ends on 283FFF



For the Windows key, search for hex values 01 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 1D 00 00 00, the key is in plain text, then copy the whole block starting from the 01 00 00 ... , past an string "MPMLock" until you see the FF FF stop showing up
In this example it starts at offsets 2A5000 and ends in 2A6FFF, the example Windows key is ABCDE-FGHIJ-KLMNO-PQRST-UVWXY


When you copy those blocks to the "new" BIOS, use "Paste Overwrite" option in your hex editor

As for Intel ME region, i checked your bios with ME Analyzer and it looks llke it has a clean ME region (shows as "File System State: Configured")

-------------------------------
But it looks like you have a hardware problem, you can't fix liquid damage with a BIOS flash...

Yes I have been reading there, but can not get head or tails, one problem I have is the firmware repo has up to 13.0.60.xxx.CON_LP and I need 13.0.65 am not sure if downgrade is permited...

Thank you! very helpful. I did run into a problem.. on point 1, I searched for my Serial Number and found 3 mentions (blocks, offsets, whatever ?) of it so which to choose ?
Point 2 windows key no problem I found it..
Point 3, yes I am aware I uploaded a fresh extracted copy from HP website as reference only... I did not want to upload oringinal backup so I can do it on my own...
Point 5 I am aware I´m working on that as we speak, I´m currently waiting on replacements IC controller...

So how do I choose which block corresponds to DMI data ... ?

Also there seems to be a bunch of UEFI secure boot keys for example:

(http://pki-crl.symauth.com/ca_e8b315...atestCRL.crl07)

do I also have to copy all that ...?

Attached is image of serial number blocks I find ....

The block from 480000-4810FF, don't forget the "Build ID" and "Feature Byte" (starts with 3K....., it's also inside the back cover on a sticker) which is below a bunch of FF FF on your model
Example from a random HP 14-dq0xxx BIOS i found, the offsets are different but the length is same, as yours is a 14-dq1xxx

No need for the secure boot keys, the default keys from MS will get restored (i think)

On 2. select from the offset you find the Windows key until you get past "MPMLock" found after the Windows key, or it will say "Manufacture Programming Mode is in Unlock Mode" when you power on the laptop, on the HP 14-dq0xxx the Win key starts at 76D000, MPMLock is found at 76E000

I got it ... I hope it will bootup after I restore shorted IC´s and/if CPU is not bad .......

Also just in case someone else is reading this, windows key is at offset A9E000, MPMLock at A9F000 and finished at A9FFF0 (Block
A9E000 - A9FFF0)

Thank you! Thank you!
