Could be, from another forum:
You might need to inject form old dump sn,mac,win key
from address 21048d to 2330ff to this one.Comment

Thank you soo much my friends but you lost me at "You might need to inject form old dump sn,mac,win key
from address 21048d to 2330ff to this one". AS MY OLD CHIP SAYS IS BLANK.
Would this work if i use it just the way you sent it?Comment

Re: does anyone has X551CA Bios dump ? laptop power gets to the first mosfet then not
Yes it should work without these numbers, but you might have windows license problems, network card problems...
If old chip was all blank, then you have nothing to copy from there.Comment

Hi
Yes fixable the only way is get a donor bios and rebuild the me region ...if you just use a donor fans will be full speed or reboots all caused by me region once a intel computer boots it's married to that computer ....not the case for amd plateform .
i could do it when i'm not so busy

Bad bios chip?
Bad contact with chip?
Bad programmer?
I am not familiar with this programmer software - does the chip get id-d correctly?
I have used many times dumps from donors without rebuilding the image.Comment

Re: does anyone has X551CA Bios dump ? laptop power gets to the first mosfet then not
this chip is a Windbond 25Q64FVS1G but the software detects a 25Q64BV, this might be the reason why. Couldnt find it manually either.
Would you recommend a good software that is compatible with this programmer?Comment

Re: does anyone has X551CA Bios dump ? laptop power gets to the first mosfet then not
If it is a 25Q64FW - then it is 1.8V flash - then it needs an adapter.
Can not find an 25Q64FV datasheet...Comment

Re: does anyone has X551CA Bios dump ? laptop power gets to the first mosfet then not
my friend , if voltage is not passing true first mosfet , then lift second mosfet , and inject 19 volts again and chek if you now got voltage on the outher side of the mosfet .. and also if gate voltage is correct . if so replace the mosfet you lifted and simply is fine to turn on .. alltough and one member sayed , first mosfet are controler by charger IC ,, so i believe you got a bad FET or could have something wrong with charger icComment

Re: does anyone has X551CA Bios dump ? laptop power gets to the first mosfet then not
alltough if you reading a dump that is empty could be causes due to incompatibility with your rom flasher (time to times you have to install new firmware for you hardware (it will also add new chips to the system read) i had problems with a few samsungs , bad reading etc etc , after firmware update , all good now
but in any case if you bios is dead Techman is a great HEXA guy he will fix you this for sure .Comment

Re: does anyone has X551CA Bios dump ? laptop power gets to the first mosfet then not
Thankx a bunch guys. I found two other boards with the 25Q64 bios chip, but i dont know if they are compatible. i got a 25Q64FWS1G from a Toshiba C55 and a 25Q64FVS1 from a dv6-7000.Last edited by Blacktek; 08-18-2015, 11:04 AM.Comment

Can i use a different software for my hardware? If so which one, im using the CH341A programmer but it doesnt really work for all 24x,25x chips.alltough if you reading a dump that is empty could be causes due to incompatibility with your rom flasher (time to times you have to install new firmware for you hardware (it will also add new chips to the system read) i had problems with a few samsungs , bad reading etc etc , after firmware update , all good now

The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).
I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...11-17-2023, 10:56 AM -
Hello,
I'm requesting a full BIOS dump (including EC firmware) for an HP OMEN 17-an012nf laptop.
Details:
Model : HP OMEN 17-an012nf
Motherboard Part Number : DAG3BAMBAF0 REV : F
Serial Number (S/N) : 5CD7280D51
BIOS chip : Winbond W25Q64VSIQ
Programmer : EZP2023+
Issue : The motherboard is not powering on. Only the 5V rail is present. The 3.3V rail is missing because EN1 on the SY8286B remains stuck at 0V. This signal is driven directly by the EC/SIO. I replaced the 3.3V regulator and confirmed it's working.

This laptop is the same laptop I was working on in this thread and I wasn't sure if I should post a new topic or post in that thread because I already solved the issue that thread was discussing and this is a completely different issue although it is dealing with the same laptop. I decided to make a new thread since it's a new issue, but please move if I made a mistake.
Motherboard model number: DA0PAMB46A1 REV: A
Secondary motherboard model number: 0PAB
SKU: 685K4UA
Serial number is: 5CD3223BJP

Hi,
I need a BIOS dump for MSI Z590 PRO WIFI from a real physical board, along with MAC address and serial no.
It must be a dump from a physical board, as it contains personalized data eg. MAC Address, UUID, Serial no.
I have a board which has lost the BIOS contents, I have the MAC and serial to this board, and need to insert it into the another BIOS image. To do it, I need to have a real image from a real board, as the images from the MSI site are without this data. The only way to find where MAC/UUID/Serial is located in the BIOS is to have a bios...11-06-2022, 05:22 PM
