Hello,
I am trying to repair a Dahua NVR4216-4KS2 that is not booting.
The main BIOS/firmware is stored in an SPI flash EEPROM (Winbond 25Q128, labeled as U130 on the PCB).
I have a CH341A programmer and I already attempted the following steps:- Identified the correct chip (W25Q128, 3.3V SPI flash).
- Tried to read the contents with CH341A Programmer software. The dump seems corrupted and I often get the error: “Chip with the contents are in disagreement.”
- Compared several chip type selections (24Cxx and 25Qxx families) to confirm it is indeed a 25 series SPI

Hi folks,
I got a Dell Optiplex 7010 micro PC (Exact Model) with 8FC8 BIOS and locked out admin password. I attempted to remove the password by patching the BIOS via info from this thread: https://www.badcaps.net/forum/troubl...ssword-patcher
After flashing the patched the BIOS, the PC is unresponsive with a solid AMBER power LED (not documented in manual anywhere)
Steps I took:- Read BIOS with CH341a, verified hash twice

I usually try to figure these things out on my own but am asking for help now as I have been beating my head against a wall.
Backstory, I initially ended up with a CF20 Mk2 with a locked BIOS. I used aptio to read the BIOS and made the adjustments to the .rom file and attempted to write it back with aptio before reading other users problems with that setup. Well it bricked the BIOS go figure. Computer no longer boots, black screen. I found a clean BIOS on this forum but now I am having ME issues. So I would rather hand over the aptio dump(pre BIOS brick) and a hardware reader dump(post...
