[Xiaomi Mi 4C] wolkenjaeger:
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 (I am an Android developer, so I have this installed already - unsure if you need specific ADB drivers for Xiaomi devices though)

- 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_b09dac70a0.tgz - unpack until "images" directory is visible!

- [Optional] Mi4c Fastboot Image: miui_MI4c_6.1.21_d1d054460d_5.1.zip

- [Optional] Latest TWRP: http://xdaforums.com/mi-4c/development/libra-twrp-3-0-t3315059

- [Optional] Latest build of CM 12.1: http://xdaforums.com/mi-4c/development/cm12-1-build-cyanogenmod-12-1-device-t3291631

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

V8.6.9.15 MIUI Dev ROM

V8.0.16.0 MIUI Dev ROM

V7.5.4.0

V7.5.3.0.LXKCNDE

V7.1.4.0.LXKCNCK

V6.1.21 (Download link above)

V6.3.24

V6.3.17

V6.4.21

V6.4.14

V6.5.26

V6.8.25

V6.9.15 (China Dev)

Not confirmed (?)

None

Not working

None

(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)

When completed, reboot the phone by holding the Power button long (~8s)

Wait until 6.1.7 is completely loaded (this may take a while)

Reboot into fastboot mode (Power + Vol Down)

Command: fastboot oem unlock -> at this point you should have an unlocked bootloader

Now optionally install TWRP and subsequently CM 12.1 and enjoy (see respective linkes in the requirements for a howto) - TWRP: fastboot flash recovery <twrp>.img

With this post, I want to say thank you to all the developers who take their time to port Cyanogen to exotic Android devices. You are heroes!

Great post.

Very detailed explanation.

Very usefull.
[Xiaomi Mi 4C] nhkhanh068:
could i back to miui rom after installed CM rom
[Xiaomi Mi 4C] Logic_:
Yes you can, as you see the CM is optional, you can choose any rom of your liking.

Be warned that any of the latest official Miui roms will lock your bootloader right back and if you have TWRP in place, you will bootloop.

Xiaomi.eu or sMiui highly recommended alternatives if you want to go with miui.

Great step by step tutorial, worth a sticky imo since more and more people coming here will be locked in the future.
[Xiaomi Mi 4C] vasil_d:
I did unlock the bootloader using the guide and it works.

Step 1 Downgrade your Mi4c by flashing the 6.1.21 image via the "Updater" app (use top right icon to select image) is not necessary .

Also all data will be wiped.
[Xiaomi Mi 4C] wolkenjaeger:
Thanks for the feedback. Did you "EDL" flash from the latest stable / dev version?
[Xiaomi Mi 4C] Ettenmoors:
Not working for me. I'm Unable to flash 6.1.7 from update from 6.3.10. When I send command: fastboot oem edl phone reboots and then I am unable to glash with MiPhone. :crying:

fastboot oem edl

Hi guys i need some help, when i try to use "fastboot oem edl" then flash it all it gives me black screen and cannot go back to fastboot.

no key combination is working power+vol - is dead power+vol up is also dead..

all i can see is its recognize it via device manager port com "Qualcomm hs-usb qdloader 9008"

please point me out to somewhere i can see my fastboot mode again :(

thanks in advance :)
[Xiaomi Mi 4C] wolkenjaeger:
Well, when you get the black screen, start MIFlash :fingers-crossed:
[Xiaomi Mi 4C] ding-dong:
i did that several times but nothing happend it said tobe successfull but i cannot open my mi4c.. can u help me to get back to fastboot?

i dont have anything now... :(
[Xiaomi Mi 4C] TheArt.:
But.. How can I check if the bootloader is locked / unlocked? In fastboot nothing useful is displayed
[Xiaomi Mi 4C] matt0101:
hi,

everything going fine for me, unlock worked, flash recovery twrp worked. But finally i still have the miui recovery...

Now when i try to unlock through MiFlashUnlock, it says "Devices already unlock". Before doing this guide i was blocked at 50% "Mi account not the same that devices information".

What can i do ??﻿
[Xiaomi Mi 4C] tuanhung303:
don't let en.MIUI rom boot after you install twrp. because it will reinstall the stock recovery over the twrp recovery. In fact, you have to go directly to twrp after flashing it, and try MIUI.eu or other CM roms.
[Xiaomi Mi 4C] matt0101:
Thanks you very much, it finally works !!!

Upgrad from MIUI 8 to CM 13.1 !

Thank you!

After upgrading Mi4C to MIUI 8 (which is a disaster) i was not able to unlock the bootloader and was not able to downgrade. Xiaomi unlock tool got stuck at 50% and I was not able to progress for 2 weeks.

This guide resolved my issues. I've installed CM 13.1 finally!!
[Xiaomi Mi 4C] Monnq:
Does it still work on MIUI8? Can I brick my phone with this?
[Xiaomi Mi 4C] clarify:
Mi4c Bootloader Unlock Guide

New to Android (iOS + OS X) and I have to say, although it is well-organized :good:, I do not find this to be a particularly comprehensive, STEP-BY-STEP guide for me.

I do understand bits and pieces of it, but more specifics would be incredibly helpful - I cannot tell, for example, if you are using a PC or not ('exe' file in 'Requirements'). :confused:

Am planning to purchase a Xiaomi Mi4c phone shortly, with the hope of eventually flashing a CM Nougat-based ROM (firmware) onto it.

And I would like to be able to do it, using the phone only (no access to a PC), so a more elaborate guide would be truly appreciated!

Thank you!
[Xiaomi Mi 4C] Monnq:

[Xiaomi Mi 4C] mesziman:
These 2 commands are perfectly enough
[Xiaomi Mi 4C] Shrapnel2:
Massive thanks to the OP for this. Recently got a Mi4C and the ram management in MIUI is so irritating, Cyanogen Mod is much better. I did this from step 2 coming from 7.5.4.0 which is the latest available version on MIUI for this phone, worked like a charm.
[Xiaomi Mi 4C] Tantomare:
"fastboot oem edl" working confirmed on 6.8.25.

I had an issue at next step "Use MiFlash to flash 6.1.7 image", when Miflash couldn't open COM-port.

Unfortunately I can't find topic on miui.com with similar questuin, but latest Miflash beta-version resolved this problem.

All next steps passed fine.
[Xiaomi Mi 4C] SH1M4BD3:
try different port, restart your pc (on your case pc didn't recognized the QHSusb 9008 mode), reinstall miflash, disable driver signature on Win8 above
[Xiaomi Mi 4C] Schatten777:
Hi, I tried to follow your guide, but unfortunately I'm already on MiUi 8, 6.9.1, China Developer Rom. The problem is, when ever I wan't to flash with MiFlash to Rom 6.1.7 (or any other Rom, same thing), MiFlash shows an error after a while: "ping target failed". Up to this point everything works, but I can't flash my Mi4C... what can I do?

Thank you!

//EDIT: Solved the problem for myself: Just use MiFlash Beta, instead of the normal version! Then the flashing works perfectly!!!
[Xiaomi Mi 4C] dimipage:
fastboot oem edl works also with Developers Rom MIUI 8 Version: 6.8.25
[Xiaomi Mi 4C] khalifaardi:

[Xiaomi Mi 4C] Kan_narhio:
One more here that sucessfully unlocked Mi4c bootloader! :)

Only thing I did different from this tutorial, as someone already mentioned, was using MiFlash beta. MiFlash was returning the "ping error".

Before the process I had V7.1.4.0.LXKCNCK installed.

Thank you wolkenjaeger! ;)
[Xiaomi Mi 4C] bonz_zzz:
dear fellow mi4c users,

is it possible to have internal storage partition into 2 ? so i could have 1 "internal storage" that could be wiped when i clean installed new rom and 1 "external storage" that no need to be wiped when installed new rom?

I tired of copying my data (10gb) to otg first everytime i installed new rom

many thx
[Xiaomi Mi 4C] sixtheninth:
hardbricked through attempted unlock

Perfect, Step 1 has hardbricked my phone into -not charging - not even starting phone. I tried to fast-boot and flash from MIUI 8. Now I am ****ed.

- now my phone won't even start despite MiFlash reported a successful flash operation, but after initial reboot brought me back into MIUI 8 (so no downgrade actually happened) ... then I powered it off and phone went dead - no boot, not even charging LED fires up anymore---any advice?

Cheers

[Xiaomi Mi 4C] flor90:
I used your guide, and I managed to flash cm13.1 successfully. One thing though, after unlocking bootloader, I didn't know the key combination for booting in recovery mode, MIUI booted instead and replaced the TWRP with MI recovery, so I did this: instead of long pressing power button after flashing TWRP, I used the command fastboot boot recovery twrp.......img. Maybe you could add this step to make it easier for anyone. Thank you very much for this thread!

[Xiaomi Mi 4C] wingsoflight:
perfectly works on MIUI 8.6.9.15 developer ROM
[Xiaomi Mi 4C] schachi92:
Worked fine! Was on MIUI 8.0.16.0 before, Shop was banggood.

A few additions:

- Make sure driver signature is off, else miflash won't work in EDL mode:

Press (Win) + (X) and enter following:

BCDEDIT –Set LoadOptions DDISABLE_INTEGRITY_CHECKS

(Enter)

BCDEDIT –Set TESTSIGNING ON

(Enter)

Reboot your Windows.

- ADB DriverInstaller didn't work for me, use "15 seconds adb installer 1.3.0" (somewhere mentioned above or google)

- Place the fastboot and adb files directly in a folder on C:, not on dekstop or somewhere else.

- Use miflash beta. Make sure when in Phone is in EDL mode that it is listed as COM Port in device-manager. If not try to install this driver:

[MENTION=6808045]wolkenjaeger[/MENTION] what are the chances a similar method will work on Mi5?
[Xiaomi Mi 4C] wolkenjaeger:
I have a Mi5 and I had to unlock it via the Xiaomi Unlock tool. I doubt it's possible with this method, because there is no existing ROM before the introduction of the Unlock Tool for the MI5, which is basically the required backdoor for this method.
[Xiaomi Mi 4C] ermacwins:
If I buy a used mi5 but don't have the original mi account that was used initially used, can I still unlock the bootloader?
[Xiaomi Mi 4C] wolkenjaeger:
You should be able to wipe the device and then just login into your MIUI account to have the device attached to your account. After that, I guess you need some patience to unlock via the unlock too. For further discussion, please use the MI5 forums.
[Xiaomi Mi 4C] best98:
For the detail.. I requested the unlock code, it came after 12 hours but once running the tool the XiaomiUnlock app could not verify my phone..

So.. followed this sequence.. and all good !

I had to use the XiaomiFlash version 20151028 provided -I had the newest one from 201608 installed, but it just didn't work.

Then wiped System, Data, Dalvik, and all needed as the install requires it.. flashed the latest cm-14.0-20161013-UNOFFICIAL-libra.zip and am happily running CM14.. with TWRP 3.0.2 :)

Thanks !

Hello ,

I have just received my third MI4c (because all of my family is going to buy one ! :D ) , and i'm actually doing the third time unblock bootloader + install TWRP + slim rom.

But i'm stuck on the first step -> downgrade to 6.21 because my miui updater app is saying , when i want to install the 6.21 zip , i need to download File Explorer , i did it but it's continuing to say that...

I'm on stable 8.0.16.0 | Stable , USB debugging activated and adb OK.

I tried to do directly the 2nd step but it don't work , can you help me ?

EDIT: look that , i have the same problem https://xiaomi.eu/community/threads...-50-and-unable-to-flash-dev-rom-newbie.35697/

[Xiaomi Mi 4C] DrYoox:
Hello! I'm Kayoo, the guy who post on Xiaomi.eu forum. Glad too see that I'm not alone to have this problem. Where did you buy your phone? I bought it on alliexpress Hong Kong Goldway store (8.0.16.0 LXKCNCI_20151104_SZ version). I checked this one with malware bytes and there is a Trojan on the Note app, without removal possibility. I really want to install the xiaomi.eu rom but I'm really afraid of brick, especially after you enter the edl mode (I saw several users on forums who bricked after this step)...

Where did you buy your phone? Which firmware version do you have?

It will be nice to exchange between us about this subject ; I'm French ;)

Thank you

This post was very usefull for me.

For those who have problems, I tell you that it`s not necessary to downgrade. I was in the China Dev 6.10.20 (I think, is the lastone)

So what I did is download the adb drivers, installed the pc Suite and put the phone in edl

Then I had some Issues flashing the rom V7.1.4.0.LXKCNCK, beacuse i walways had an error with MiFlash tool. Finally I could solve it downloading the lastest version

Once I flashed that rom I flashed the last eu rom.

Thanks to the OP! :D

[Xiaomi Mi 4C] GnatGoSplat:
If you are already on 8.0.16.0 (a common dealer ROM), you can skip to step #7. That would save a lot of time.

Probably if you get any Mi-4c from Aliexpress or an international reseller and the phone boots in English by default, should try step 7-up first, because the dealer probably had to downgrade to an unlockable BL in order to flash their custom ROM.

Only a phone on a China ROM needs to be downgraded because it's the only ROM with a locked BL.

Try with minimal adb/fastboot (not the program files installer, I never trust installed adb approach, instead I use adb.exe / fastboot.exe copied to some folder I can access with command prompt).

Make a folder named ADB in your C: drive, copy fastboot.exe there. Then right click in empty space of explorer window while being in ADB folder and click "Open Command window here"

Rename the recovery img to libra_twrp.img (just a smaller name to be friendly)

Then issue the command to flash recovery.

issue the command to boot recovery (fastboot boot recovery libra_twrp.img)

Flash the CM13 + gapps

Reboot from recovery.
