Re: Samsung NP300 Bios
Every samsung bios has a platform ID ,if you open your bios with a hex editor you can find out what yours is by looking for a few key words, SECFID,SEC,SECWUP or $Revision https://www.badcaps.net/forum/showthread.php?t=88206
Use the forum search to look for an 06QA bios (or 07QA,08QA,09QA) with clean ME firmware,if you can`t find one look though all the NP300E5E threads,download each bios and open with a hex editor and search for QA.If you can`t find anything then you should try cleaning the ME region of your bios,if that doesn`t work then download and extract the QA bios update,extract it and merge it with your bios using a hex editor or version 0.27 of UEFITool.The serial number and other DMI will be missing after flashing,if you want to add the serial number (DMI) from your backup use a hex editor,the offset is 381000 (length 4000) or use UEFITool and extract the EVSA area at 381000h,and copy it into the newly merged bios region.

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

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.)

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...
