[All-in-One] Xiaomi 14 (houji): Unlock Bootloader, Root, Flash TWRP, Flash ROM


Dear Xiaomi 14 user,

This AiO does not work for the China version of Xiaomi 14 (houji) due to very tough restrictions that Xiaomi has put on unlocking the bootloader for China dedicated devices.

I'm not responsible if anything happens to your device. If you execute these AiO procedures properly then you shouldn't face any problems. Before you proceed please back up all your important data and make sure that your phone battery is charged >80%!


A. Prerequisites:

1. Install ADB and Fastboot tools with drivers on Windows

Download the latest ADB and Fastboot tools from here:

SDK Platform Tools release notes | Android Studio | Android Developers

Android SDK Platform-Tools is a component for the Android SDK.

developer.android.com

and install them in your computer. Restart your computer.

2. Enable "OEM unlocking" and "USB debugging" in your device

a. Enable Developer Options in: Settings/About Phone/OS version. Click on it 7 or 8 times
b. Now go to: Settings/Additional Settings/Developer Options and check "OEM unlocking" and "USB debugging"

3. Create a Mi Account

If you don’t have a Mi Account, then create one here: https://account.xiaomi.com

4. Apply for permission to unlock the bootloader

Go to your Xiaomi Community App, sign in with the same Mi Account you want to add to your device and apply for permission to unlock the bootloader.

+ Open Xiaomi Community App, go to “Me” then “Set Up” then “Change Region” to Global
+ Go to “Me” then “Unlock Bootloader” then “Apply for Unlocking”

If you don’t see “Unlock Bootloader”, update Xiaomi Community App to the latest version and you’ll see it.

5. Connect your Mi Account to your device

Go to: Settings/Additional Settings/Developer Options/Mi Unlock status and check "Add account and device"

6. Some Additional Information before unlocking the Bootloader:

+ You can unlock your bootloader only if your Xiaomi account is older than 30 days.
+ You can unlock the bootloader of max 3 smartphones per year with your Xiaomi account.


B: Unlock The Bootloader

Attention: Unlocking the bootloader will erase all your data! So please back up your data before you unlock the bootloader!

1. You must enable "OEM unlocking" and "USB debugging" as per point A.2.
2. You must connect your Mi Account with your device as per point A.5.
3. Download Mi Unlock Tool here: https://en.miui.com/unlock/index.html
4. Enter the fastboot mode by holding together "Volume Down + Power" and connect your device to your computer via USB cable (best would be the original cable)
5. Start the Mi Unlock Tool
6. Enter your eMail and your password of your Mi Account (the same account which you added to your device - Point A.5.)
7. Connect you device to your computer and start the unlock procedure
8. Follow the unlock tool instructions until the unlock procedure is finished
9. Reboot your device


If you want to keep your original HyperOS Rom but want to root your device then continue to point C.

If you want to install an alternative Rom,

+ Xiaomi.EU Rom then please skip point C and continue to point D.
+ LineageOS, Evolution X etc. then please skip points C, D, E and continue to point F and then point G.


C: Root Your HyperOS ROM without TWRP

1. Your Bootloader must be unlocked (see Point B).
2. You must enable "OEM unlocking" and "USB debugging" as per point A.2.
3. Download the fastboot ROM (the same ROM which is currently installed in your device) from here: https://mifirm.net/model/houji.ttt and unzip it.
4. Open the file and extract the "init_boot.img" on to your computer.
5. Transfer the “init_boot.img” from your computer on to your device.
6. Download the latest Magisk manager App from here: https://github.com/topjohnwu/Magisk and install it on to your device.
7. Open Magisk App and click install, and then "select and patch a file" (of course you select “init_boot.img”).
8. Transfer the patched init_boot.img file from your device’s download folder on to the “ADB and Fastboot” folder in your computer. In the computer rename the patched file into: “patched_boot.img”.
9. Switch off your device. Now enter the fastboot mode by holding together "Volume Down + Power" and connect your device to your computer.
10. Check if your computer recognizes your device. Go to “ADB and Fastboot” folder and enter the terminal command in command line: >>fastboot devices<< and hit enter. You should see your device now. If not, then please recheck if you have installed the drivers properly.
11. If you see your device then write the terminal command in command line: >>fastboot flash init_boot patched_boot.img<< and hit enter. Then write the terminal command in command line >>fastboot reboot<<. Now the device will restart.

Attention your device is now only temporary rooted, so don’t restart your device again just yet.

If my guide helped you, please click "thanks" and enjoy your phone.

Hello everyone, first of all, sorry for my English if you don't understand everything (I use a translator). I have had a Xiaomi 14 with Chinese/English ROM since March. And I wanted to upgrade to EU or EEA ROM to have the new features and a version available in French.

But I'm desperately browsing forums to find solutions to my problem and this is where I understand the best. Thank you for making this tutorial!

However, I also read that this is only available for all ROMs other than the Chinese/English ROM.

So I ask my question to be sure of my understanding, is it possible to change the ROM of my X14? I recall the version I have:
1.0.45.0.UNCCNXM

Thank you and have a good day

In order to be able to install any ROM including xiaomi.eu ROM, it is necessary to unlock the bootloader first.
If you have a CN version of the device, you need to find a paid service to unlock the bootloader.

Okay thank you, do you know where we can find this? And how much would it cost?

PSA: Official bootloader unlock request method via xiaomi community app no longer works, giving bullshit errors.

See comments below this article, for examples of the issues people are facing https://new.c.mi.com/global/post/710306
The most common error is "quota error", suggesting trying again next day, but reappearing the second the day starts.
Some users (including me) have been trying for months with no luck.

There are supposedly paid services to unlock the bootloader, but many users reports these as fake.

What has worked for me was the "php bypass script", used as described in this article: https://xdaforums.com/t/how-to-guide-bypass-xiaomi-bootloader-restrictions-global.4698954/

I'm not sure about the trustworthiness of the scripts downloaded from random links, but this has worked. There is similar script at github (maybe the same?), but I haven't tried it: https://github.com/MlgmXyysd/Xiaomi-HyperOS-BootLoader-Bypass

In any case, these seem to be the only reliable approaches for bootloader unlocking on Xiaomi 14.

Edit: Note that the "php bypass tool" will only bypass the xiaomi community app request requirement, all other requirements for the unlocking - account standing and age, device region etc. - stay the same (AFAIK).

Are you going by China time zone for the start of the day?

I did mine in March. Maybe they lowered the quota?

Yea, exact time, as given in the app itself (it prints the timezone too). Tried it even a minute sooner, later, etc., no help. People report sitting on it and pressing it exact second, with no luck.
