unknown device in device manager after flashing wrong firmware

[K4sh]

You need a screwdriver and a brain
Safely remove back cover battery and back case.
According to the screens, short-circuit between two points on the board with a wire.
These are TP7 & TP9 (red marked in picture)
Connect your phone to a computer without a battery.
In device manager you will see device as Qualcomm HS-USB QDLoader 9008
Now, you can remove the wire from Test Point.
Open QFIL click Download
After the firmware is flashed connect all body parts and enjoy the phone.

Yes, these are the test points above the memory card slot. May be your motherboard has certain variations.just click the photo of motherboard and attach here.
And also you have to connect USB while short circuited TP7 & TP9 and than you can remove wire when connected to download mode.

2 copper points in red circle are to be connected.
Take 2 needles, hold in v shape and point the 2 ends on both points ask any one to connect USB cable to PC while holding needles, the phone will be attached in download mode.

Install USB deview and check whether any devices are connected like USB input device,USB root hub,generic USB device. If yes then your device can be unbricked.
For me too it didn't shown any thing on device manager(rarely it shows as HID compliant device when i try to enter download mode)but USB deview did.
Just give a try it will work unless it is a hardware problem

You have to connect USB cable while shortcutting the 2 points
Read carefully whole thread, if it not works than it is a hardware problem
