This evening I had the same problem like many of you and I just did not want to wait 2-3 weeks for the unlock code from Xiaomi. I went through a lot of threads and different forums to create this guide.

Requirements
- ADB up and running
- Xiaomi MI4c
- MiFlash:http://bigota.d.miui.com/tools/MiPhone20151028.exe (via http://en.miui.com/a-234.html) - Install
- Mi4c Image:libra_images_6.1.7_20151221.0000.11_5.1_cn_b09dac7 0a0.tgz - unpack until "images" directory is visible!
- [Optional] Mi4c Fastboot Image:miui_MI4c_6.1.21_d1d054460d_5.1.zip
- [Optional] Latest TWRP

Step-by-step

Step 1 is optional: I was not sure, if I could use the "fastboot oem edl" command in a higher version of MIUI... feedback required. Thus following is a list of known Xiaomi ROMs which support this procedure:
If you are using one of the following ROM versions, you should be able to unlock the device easily with the provided guide. However, I have messages that the versions don't work with higher MIUI ROM versions.

CONFIRMED WORKING
V7.1.4.0.LXKCNCK
V6.1.21 (Download link above)
V6.3.24

Not confirmed (?)
V6.3.17

Not working
No information on this
  • (Optional) Downgrade your Mi4c by flashing any image from the list above via the "Updater" app (use top right icon to select image).
  • Reboot into fastboot mode (Power + Vol Down) until you see the MIUI rabbit and "FASTBOOT"
  • Command: fastboot oem edl (this brings your device in a kind of emergency recovery state) -> the device does only show a black screen. Do the next step.
  • Use MiFlash to flash 6.1.7 image (Browse -> select the "images" directory of the 6.1.7 package and start flashing)
  • Reboot until 6.1.7 is completely loaded (at this point it may take a while)
  • Reboot into fastboot mode (Power + Vol Down)
  • Command: fastboot oem unlock -> at this point you should have an unlocked bootloader.
  • DONE.
