Windows 10 keeps flashing upon boot, BIOS accident, nothing works

[John Huynh]

When I got first got this tablet, android was working fine but Windows 10 was flashing after signing in. Surprisingly, the slide down to turn off device still works, I can sign in wifi, and anything else you can do on the front page. I decided to go to BIOS and I think I activated DNX fastboot mode. Now, the usb otg doesn’t work, so I can use a keyboard to get into BIOS again to deactivate it. Now android is always on the “Android is starting” page optimizing apps… than reboot and does the same thing again.

Can anyone tell me if there is any way to revert the BIOS, way to get into BIOS, or do a clean wipe of the tablet and only installing Windows back on, preferably Windows 8 if possible. If I can revert the fastboot, can someone help me fix Windows? Drivers, faulty copy of Windows?

Can you get in BIOS by windwos?

1. Open Settings, and click/tap on the Update & security icon.
2. Click/tap on Recovery on the left side, and click/tap on Restart now under Advanced startup.
3. After the PC restarts, click/tap on Troubleshoot.
4. Click/tap on Advanced options.
5. Click/tap on UEFI Firmware Settings.
6. Click/tap on Restart to boot into your UEFI firmware settings.

I forget to say that after going to BIOS, on start up, it only goes to android. Then I goes to android is starting page and so on. And I CAN’T use the usb otg.

Then again, I activated something I don’t remember, something about making something faster or optimizing something. DNX fastboot is somethjing different. My mistake.

Hello John,

 

Were you able to figure out how to fix it?

[John Huynh]

No I wasn’t, I remember that I activated something with turbo in BIOS and now my tablet is in this state
