Are you able to enter in fastboot with keys combo?
If so you might try the following tool
Read carefully the file readme.md before starting

You can boot twrp in fastboot mode and make a format data ( fastboot boot twrpname.img), use official twrp, try to Finish setup, enable developers options, enable usb debugging oem unlocking options, then go back to fastboot mode and type fastboot oem unlock

Maybe this helps

Download this Tool and Install, connect your Phone, then use on the right Side Flash factory, choose your original image and install.
Then finish the Phone Setup, activate Developer Options, activate OEM unlock and USB Debugging and retry to unlock and install twrp.

Well i think the last resource is trying to unbrick your device with EDL mode
But you'll have to physically open your phone
Once connected test-point and phone with usb cable you'll be able to see in device manager a new device
Use some metal tool like tweezers to connect the test points together
While holding test-points together connect your device to pc
After new device appeared in device manager you can release the test-points and continue
Press “refresh” in MiFlash tool
A new device should also appear
This means that everything is good and you've entered EDL mode
Then you'll have to flash phone
Here an example/tutorial
