Ami Aptio 5 change values or reset to default

[UrosS]

Hello,

I have problem with mi Ami Aptio 5 UEFI bios.

Long story short, I foolisly disabled USB support (EHCI, XHCI...) and now I can not operate with tablet since nothing on USB ports work. And [censored] tablet does not have reset switch, button, jumper, battery remove did also not help.

Ta tablet is Odyn Windesk plus 3G V2, Intel Atom tablet with win 10 installed.

So far what I managed to is:

1. Make bios dump with SPI programmer CH341A and AsProgramer 1,41
2. Installed software on my laptop for managing Ami Aptio 5 bios (UEFITool NE A58, MMTool 5.02.0025, AmiBCP 5.02.0031 and HxD
3. Surf through forums for posssible solution
4. I also found same tablet and try to swap bios chip but the tablet wasn't working, but works again with original chip.


Now I don,t know what to do next, I was thinking about clearing NVRAM volume on bios chip? Do I assume correctly that volume will be populated with default values?
I need advice from professional. Or maybe find settings for USB and edit hex code to enable it.

More info about device:
Device: Odys Windwsk plus 3G v2
Bios: Ami Aptio 5 version 5.0.0.7
Bios chip: Winbond 25Q64FWIG

Thank you for your help.

Uros
