i, too, have bricked my new Minibook 4100 on day 1 by choosing the fatal option of Linux inside the BIOS. I was trying to remedy a non-functioning touchpad and a somewhat noisy fan.
Now my device does not boot, no Chuwi-Logo, just the lit keyboard. The key for switching the keyboard on and off still works. I have tried to flash the BIOS with the files provided in this forum - without success.
I also have tried any keyboard combinations on startup and am now waiting for a response from the Chuwi service, whom i have emailed.
In the meantime, i would like to hear how (If?) others successfully got out of this situation. I am thinking about blind-circling through the bios in case that only the display does not work, but i cant remember the correct sequence to disable the Linux option. I have no mini-HDMI at hand, is it worth to by one to connect to an external display?
Such a pity that this problem exists on this otherwise very nice device.
