    GL552JX usb 2.o port stopped working after Bios Flash

    A few days ago i updated my laptop bios (GL552JX) and the usb 2.o port stopped working the bios doesn't recognize It although the usb port has power (I have checked) so I have come to one final conclusion, I have to flash back to an older WORKING bios but I can't see to force the bios to flash, It keeps checking for the date of bios, so I hope someone can help me flash/fix this issue.

    After a simple sub-forum search of "downgrade bios", As pointed in this thread, you can launch the flashing app winflash with a switch "winflash.exe /nodate" to be able to bypass the date checking that prevents you from downgrading the bios.

    Also, I can suggest you restore the "manufacturer DEFAULT" settings after the downgrade process, then reconfig whatever you want.
