I have tried everything that I can think of here, but somehow my Win10 PC won't finish the driver installation.
I tried fastboot mode, recovery mode, MTP connection, USB debugging mode. Win10 fails to recognize the drivers at all. I also tried the universal drivers, they failed too. Just "Install failed" message when I use universal drivers.
I also tried removing all USB device drivers, but that didn't work either. So, right now, my phone is stuck in a weird position. I can't fix my IMEI issue because I can't connect to PC. And I can't connect to PC because it does not get installed properly. Device is getting detected but the device manager just shows error saying "A file could not be found", or "An installer cannot perform installation". No proper error code available here, but I can definitely provide exact error messages, if that helps.
Error Message in Fastboot/Recovery Mode: Device USB\VID_0BB4&PID_0C01\8PR8EMEEWCOFQ8AI requires further installation.
Edit: Tried removing every usb driver, then reinstall, then use Lenovo usb drivers. Same problem. The drivers do not get installed.
