Re: 840 g1
do not use the clip..draw wires from the chip to the programmer if you cannot remove the chip from the motherboard ... use one of these programs ..

I tested, replaced everything (programmer, clip, cable, usb port...) and the result remains the same :
when i put the clip on the chip it the software it detected the good chip then no more connection on it
Detection fails could not find the chip with CH341A Programmer soft 1.30 or
1 fast small blink then completely yellow led on ch341 with asprogrammer
whether I put the power on or not same thing...
Chip is Winbond W25Q128FV

Hi all,
This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A). I think my board was partially bricked after a failed BIOS update.
I got it second hand in this state and all the normal attempts at bios restoration have not worked. I have even desoldered the chip and tried to load the actual BIOS from HP, but it is missing some parts needed to boot the system.

Hi all,
My Samsung Galaxy Book 2 Pro 15.6-inch laptop has no display and won't boot.
The charging red LED lights up, but the charging screen doesn't show any indication.
When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
(I've tried removing the battery and resetting the device, but the issue persists.)

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.
I already...
