Hi,

I tryed to flash my old Nokia 5800's stock firmware with Windows10 tablet. But tablet always gets a blue screen on this process. I installed latest Windows10 updates. Right now its in Version 1703 15063.332. But tablet keeps getting blue screen. Sometimes with buzz sound. Windows10 totally clean it doesnt have any virus or something. I did even /sfc scannow. I never experienced like this thing before with this tablet and i didnt change any UEFI setting.

So i started to change Usb settings on the UEFI one by one and i revert it back every change to original setting. When time has comes to change xHci it damaged all Usb ports. Now i cant revert it back to original setting. I didnt change any other Usb settings. Just disabled xHci. Usb host enabled and other things. I didnt think xHci will damage all usb ports. Because on the xHci's info, Bios vendor says, it just turns Usb3.0 to Usb2.0 So my Nokia 5800 is too old phone. I thought maybe old phone doesnt work well with Usb 3.0 So i turned off xHci to Disabled.

Distributor says Tablet supports Usb 2.0 technology. After disabling xHci, Intel® USB 3.0 eXtensible Host Controller disappeared on Device manager.

I disabled the xHci on UEFI Bios and my Local named Windows10 Tablet's Usb ports doesnt work. I can access the UEFI first startup screen but i cant control it. Volume+ and Volume- buttons works only vertical movement and Power/Windows capacitive button doesnt work on that screen. Touch screen is not working too on UEFI's first startup screen. Keyboard, Mouse also doesnt work. Im stuck with touch screen. I checked Tablet's and Dock's every inch and there is no little reset button.

What happens if i spend all battery power waiting on the UEFI startup screen? Will the bios reset when the battery get empty?

Is there any way to reset UEFI using Windows10 ?

Is there any Power button, Volume+, Volume- button combination for reset UEFI?

What happens if hard reset Windows10? Will my device's Usb ports come alive?

Windows10 Tablet has a 5 pin on the lower side. This pins connecting to Keyboard(Dock) but Keyboard doesnt work. Maybe it has UEFI reset pins? I can see the HID Keyboard device on the Device manager. But removing the Keyboard physically doesnt effect HID keyboard's status.

Windows10 Tablet has 2 black coloured usb port and both doesnt work with any device. Ones Usb Type A Female other one is Usb micro b female.

Why Bios doesnt give a Warning!

Why there is a xHci setting?

Why xHci setting is changeable?

INSYDE corp. creating a Bios but they cant think "What happens when we damage all usb ports with one setting? How they can access/control to Bios/UEFI?" This is ridicilious. I checked almost all forum's allover the World and xHci info always same like my device's xHci info. I readed it and i accept the Usb3.0 to Usb2.0 changing. Not damaging all Usb ports!

If i send this tablet to distributor they will request a money for fixing simple xHci setting. Is this INSYDE corp.'s target? Who knows.
