Hello. Thank you very much for answering.

The publication you send me is for the DKL50 LA-E802P motherboard

And mine is the CSL50 / CSL52 LA-E791P Rev: 2.0

Let's see if someone can fix my file, clean it or modify it and send it with my DMI included.

Re: LA E791P REV 2.0 bios request

Thank you so much.

With this file I managed to solve the problem on my HP 250 G6.

At startup it appears "manufacturing programming mode is set to unlocked"

make more copies of the bios, check them with the HxD program and when you have more of the same, post again..

Sorry, I don't understand. Can you explane me for the next time?

Now I've tried with 08328 from hoaca388 (that I think is the officil from HP update file) and the notebook goes on but it is in "manifacturer programming mode unlock", how can I fix it?

at post # 135 you have the interval where the DMI information is found...use the HxD program (you can find it for free)..enter both bios into it and copy that interval where the DMI information is found from the original bios,
to the virgin bios on the website...(copy-paste)..

If you can't use a hex editor, use the script in this post to add it

Thank you, but the link in your message doesn't works, it transfer me to another page that isn't about DMI information address

[lzeta]

in this 3d there isn't post 135 and if I click on the link I'm redirected to this page:
https://www.badcaps.net/forum/welcom...news/135-oh-no

if I click on the other link I'm redirected to the attached page

[lzeta]

But I've seen that in the original post by hoaca388 was write the hex address....thank you so much. Sorry for the mistake

Bonsoir a tous
je me retrouve dans une impasse, mon pc portable suite a un mauvais flash bios depuis l'utilitaire HP, ma mit un ecran noir, mais le ventillo tournais, j'ai donc dessouder la puce bios, et fait un backup, j'ai recuperer un bios en version 08328, et integrer la DMI via hxd, puis reflasher via ezp2023+, j'ai resouder la puce, fait quelques tests, toujours pas d'ecran, et touche majuscule clignote 5 longs et 3 bref, j'ai suivi via la schematic les tension 19v 3.3v 5v et les autres sa a l'air d'etre pas mal, auriez vous des pistes à explorer, sachant que je n'ai pas la schematic complete de cette carte mais les documents que l'on touve sur le net ici et la, mais bon je pense suffisant, je vous donne les infos du pc et la backup du bios original corompu, et celui que j'ai modifier avec integration de mon Dmi

Good evening everyone
I find myself in a dead end, my laptop following a bad bios flash from the HP utility, gave me a black screen, but the fan was turning, so I unsoldered the bios chip, and made a backup, I recovered a bios in version 08328, and integrated the DMI via hxd, then reflashed via ezp2023+, I resoldered the chip, did some tests, still no screen, and the shift key flashes 5 long and 3 short, I followed via the schematic the voltages 19v 3.3v 5v and the others it seems to be not bad, do you have any leads to explore, knowing that I do not have the complete schematic of this card but the documents that can be found on the net here and there, but hey I think enough, I give you the information of the pc and the backup of the corrupted original bios, and the one I modified with integration of my Dmi
Thanks to all

check the connections to the bios chip, maybe you didn't write the content correctly, check the content of the bios chip again, you have everything you need at post #135..

Hey,
I have an HP 250 G6 with board DKL50 CSL52 LA E821P and SN CND8065P5W with a corrupt BIOS. I already read the BID of the old BIOS and know that I need the bios 0832E.
Now I want to copy the DMI information to the new BIOS I downloaded from the HP website.

But I don't know exactly the range which I should copy.
So Start is 210000, that is clear.
But in the thread there are different end sectors.
I guess 210FFF (length 1000) is ONLY DMI.
But what about with windows key? is it
21103F (length 1040) OR
211FFF (length 2000)

Also I'm not even sure if there was a windows key initially on the mainboard. So does it matter just copy the sector or is it not good if I do this and there was no win key?

Thank you very much in advance!!
Johannes

DMI : search by serial number in HxD.
Window key : search 01 00 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 1D 00 00 00

Ok, found sn number at 003AA00. How long is it? Till the "$END" in the text?

And the code for windows key isn't found in the bin file. So I assume that there was no key saved?
