Re: Need BIOS: Samsung RC520 (jinmao-r)
Try to look for it with the board model instead. Same applies to schematics.
i.e. - BA92-08082A, BA41-01581A, etc.
Good luck.Galaxy S6 Edge x2 (Gold&White)

Re: Need BIOS: Samsung RC520 (jinmao-r)
The file was ok..strange. But I forgot to make, on the MB, the location of pin 1
Any pointers to locate pin 1 or the schematic? Searching with the model number brings up nothing.Full-time computer repair tech (10am - 6pm) and full-time, (8am - 11pm), Ruby on Rails DeveloperComment

Re: Need BIOS: Samsung RC520 (jinmao-r)
well its easy to know wich is pin \1 put your multimeter on continuity , and chek all pins to ground , the ones that will BIP(make noise) is pin 4 GND ... therefore will be easy finding pin 1 :PComment

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

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.
Troubleshooting Attempts:

Hello everyone,
i made out of two broken Samsung Galaxy Tabpro S one that works partially.
The one Mainboard had a broken screen output but working hdmi (usb c adapter) output and the other didnt start at all.
I switch the bios chips and now the tablet starts but very very slow and it takes some trys to get it starting.
The problem is, that the micom Version doesn't match with the bios version, see picture.
How can i update the Micom Version? The Samsung bios update wont work.
With https://github.com/tavinus/SamsungBIOSTools i could extract the newest bios update...
