Reinstall Surface Type Cover Driver

Surface Type Cover Filter Device Missing

hi all,
i have a surface pro 3 with a type cover 4 (i got the surface pro4 type cover) running windows 10 and the type cover is no longer being recognized out of the blue.
I have tried many troubleshooting methods, but none have worked so far.
I opened device manager and i noticed the only keyboard category driver i have is the HID Keyboard. Looking in other threads on this issue, it seems i should have a driver for 'Surface Type Cover Filter Device' or for 'Surface Type Cover'
Does anyone know where i can find the driver for the type cover 4?
Troubleshooting steps i already initiated and none of them have worked so far:
* unclicked and reclicked the keyboard many times, while connected to the internet
* did a two button shutdown/reboot
* brought the computer up to date on windows update, did reboots, shutdowns, nothing
* reset the laptop (while maintaining all data) and then installed windows updates again + some more reboots
* installed the latest 'SurfacePro3_Win10_10586_1702002_0.msi' drivers & firmware pack for surface pro3 from Download Surface Pro 3 from Official Microsoft Download Center
* *tried* to install the latest 'SurfacePro4_Win10_15063_1702001_0.msi' drivers & firmware pack for surface pro4 from Download Surface Pro 4 Drivers and Firmware from Official Microsoft Download Center but it did not work since i have the surface pro 3
i cannot get the driver to show up anymore, and given that i never uninstalled or deleted it, i don't know what else i can do.
I am traveling and don't have access to a microsoft store to purchase a new keyboard so i am stuck and i would appreciate any help in further troubleshooting or locating the proper driver for the keyboard.
thanks in advance!

And finnaly i found my driver called: 'Surface Type Cover Filter Device' in device manager is NOT shown,that driver maybe erased and cannot detected even I update windows (I have Try). Apps like 3utools for android. Quick video showing how to get unresponsive type cover to connect to a Microsoft Surface Pro 3. Right click on Start button and select “Device Manager.” In Device Manager find the Unknown Devices with a yellow triangle on it. Right click on the unknown device and select “ Update Driver Software.” Click on “ Let me pick from a list of device drivers ” and select Keyboard and then click next.
