New BIOS v1.30 for ASRock J5004-ITX and J4105-ITX motherboards for fix the HDMI 4K output

Thanks to the collaboration of one of our readers and the support of ASRock today we bring a new BIOS for the motherboards ASRock J5005-ITX and J4105-ITX with Intel Gemini Lake processors that we have recently analyzed. Two products with compatibility problems with the HDMI 2.0 video output with 4K resolutions in the release version, with this new BIOS these problems are corrected and the multi channel audio compatibility has also been improved as you can see in the updated review, we are still waiting for a solution about the PicoPSU incompatibility.

  • You need to flash the BIOS with this procedure to full update, don’t flash the firmware file directly

I can’t update my BIOS this way, following the instructions available at ASRock website I allway fail to clear the TXE chip, I unplugged everything short the TXE pins, but when I enter the BIOS screen the TXE version nr. is always there, for what I understand it should read n\a. After that if I try to update the BIOS using the exe.bat file in windows I get an “Error 451” message, saying that I don’t have write access.


Any idea how to do this update from Linux/Ubuntu ?


I have managed to do this BIOS update from BIOS only, via “instant flash” from USB stick. It works.
