I matched the BIN before programming... Header was 100% same on both but in the middle the DATA was different. You did it very well & the BIOS even was read perfectly. For where did you get the FF FF photo, in the start it was all yy on both???? We are using the RT809H programmer, the program gives the right match for the chip with voltage. This is a 1.8V chip 256KB. Thanks

I used Neoprogramer 2.2.0.10. and CH341 flasher I2C protocol socket. Just 2 days ago I ordered SOP8 DIP8 connectors and 1,8V adapter, hoping that I would flash the BIOS chip of this laptop, thinking that the BIOS chip is 1,8V supplied. According to boardview the BIOS chip was supplied with 3,3 V, I also measured with multimeter right on the motherboard and the supply voltage was 3,3V, datasheet says supply voltage 1,8 - 5,5V. The same is with the U15 chip, I checked datasheet and range is 1,8 - 5,5V. On boardview the supply voltage for PD controller memory is 3,3 Volts. Neoprogrammer recognized the chip as 3,3V so I proceded with that voltage. Anyways, I am happy for You, that the laptop is ON again.

Hi danito. Thanks for your help. I really appreciate it. After flashing your unlocked file the computer won’t turn on.(the power button lights up for a couple of seconds and then it turns off. The computer seems to be charging the battery just fine) I tried one of the files shared by one of the guys on this post. The computer turned on fine but hard drive is not detected obviously because the bin file I flashed is for 15 model and mine is 14. Could you please advise as to what I should do next. ThanksComment

Thank you shiyab it worked. I tried to flash the file on another similar computer with the same specs. It worked but SSD not detected. I have the original password locked bios file, but it is corrupted. I am attaching it here. Please if you can extract from it the info needed for the SSD to be detected I will be very grateful.

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.

Dear all,
I have a ASUS ZenBook UX480F with the following symptoms:
I suspect it is a BIOS issue. So I decided to try to clean the ME region. I followed the guide on win-raid, and I believe I have done everything correctly. My problem is: when I open the outimage.bin in ME Analyzer, it says that it is Extracted, and not Region, Extracted as it should be. Is it normal, or did I do something not correctly? This is my first experience editing BIOS files.
I would appreciate if someone could take time to explain the issue, so that I can learn. But I would... -
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 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.)
