pumastuka

As in all works to do, lets start "IN THE NAME OF THE ONE AND THE ONLY GOD"

Hi folks, If you have unlocking bootloader problems, here is a tutorial for easy unlocking bootloader and installing twrp, root and multilang roms.

Firstly, all credits goes to Thomas who is the guy behind this perfect work!! I will try to explain his way and add some more files for you.

What we can do with this thread:

1. Flash Xiaomi 4s (Unbrick),

2. UNLOCK bootloader! (without unlock.mi website)

3. Flash MultiLanguage ROM onLocked Bootloader

4. Install TWRP Recovery(English)

5. Root the Rom with SuperSu

Steps: (BE CAREFUL, THE PROCESS IS RISKY, DONT TRY IF YOU DONT WANT WHAT YOU ARE DOING!!)

Please be noted we (thomas and I :)) will not take any responsibility for anything happened to your device. Use Windows 64-Bit, users having issue on 32-Bit Windows. You may face this error " Not enough storage to process this command"

Important: Before flashing it is advised to take the backup of data and make sure that your phone battery is charged enough.(at least %60)

1. Download and install Install the MiFlash here: https://www.androidfilehost.com/?fid=24421527759885497

2. Download and extract ROM and Tools here: https://mega.nz/#!yd8jBY7Z!umQuveopRTFlJcZeAK_3VXCypjrm2mt24hLbfIgpbCU
3. Download Root file SuperSu here: https://download.chainfire.eu/696/SuperSU/

4. Power off your xiaomi Mi 4S,then go to fastboot mode by Volume Down and Power button.

5. Click the Mi4S EDL.cmd, andyour phone will enter in EDL download mode with Red Led.

6. Make sure you have install the QualcommHS-USB QDLoader 9008 Driver

you can find the driver in MiFlash directory:

C:\Program Files (x86)\Xiaomi\MiPhone\Qualcomm\Driver\

7. Open MiFlash, Browser and loadthe Mi4S Multi Language ROM, Refresh, you will see COMXX in the Device, Then press“Flash”

8. Once flashing process completes, Remove the cable and keep Power Button pressed until it Vibrates. The Device will start, wait patiently, it can take up to 5 Minutes.

Now you have an unlocked Mi 4S with Multilanguage.

9. To install the TWRP recovery , just follow the step 4 to go to fastboot mode again,  and run the Mi4S TWRP.cmd .

10. Finally, to root the device, copy the downloaded SuperSu zip file to sdcard directory and install it from TWRP and you are done!

After installing TWRP, you may install which rom you want. Xiaomi.eu and smiui.net roms are also working with this way.

Dont hesitate to rate the topic!

Thanks again Thomas!!

Enjoy freedom now! Be careful! If you want to keep your bootloader unlocked! Update your roms over xiaomi.eu custom roms! Always seek before update the rom to stay free.

Any questions are welcome....

I received a brand new Mi4S today. In settings, the ROM version was specified as MIUI GLOBAL 7.3 (LAJCNDD)
However, it wasn't rooted and the bootloader was locked, so I decided to follow your tutorial... And it worked perfectly! Thank you very much for writing it!

However, I found some of problems during the process:
1) The QualcommHS-USB QDLoader 9008 Driver was shown with a yellow triangle in the Device Driver and the MiFlash showed an error when trying to flash it: "The system cannot find the file specified"

This happened because Windows 7 didn't want to install an unsigned driver, so I disabled this check following this guide: http://en.miui.com/thread-237673-1-1.html

After this step, the computer insisted in installing a driver for the " Relink hs-usb qdloader 9008" instead of installing the Qualcomm driver. I couldn't change the driver in the Device Manager, as my PC insisted that the Relink driver was "the best driver"

This was solved by uninstalling the  "Relink hs-usb qdloader 9008" in the device manager, rebooting and installing this version of the MiFlash Tool: http://en.miui.com/forum.php?mod=viewthread&tid=272376
and enabling USB debugging in the Developer Options (Tap 7 times on the ROM version in Settings / About Phone)

2) After I successfully installed the Multilanguage ROM, my computer stopped recognizing the Phone as a USB storage device. To solve this, I disabled USB debugging, disconnected the phone and connected it back to the PC.

Hope this can help any other user who is in the same situation as me! ;)

The only solution for you, I think, fastboot here

http://en.miui.com/a-234.html

hey, something beautiful happened. thus morning I have connected my device to my laptop. Then the LED starts flashing, the Mi PC suite had started and began to flash a fastboot ROM. Now the device is fine. ...hooooray.
Will try your ROM later again.
thanks

Hey, please tell us how you did manage that? how have you unlock the bootloader with this method? is it safe?

ydd0ras

Oh, sh....I think i have bricked my brand new device. Flashed the ROM via MiFlash. And now nothing happens. Device does not start and does not enter the fastboot mode.
Can anyone help? Any idea?

Is it really safe?  I doubt.

I tried the tools and files, no problem with my Mi4s, TWRP works perfect. But be careful on steps.
