How to Unlock Bootloader & Root Redmi 14C

If you’re using the Redmi 14C (MediaTek variant) and don’t want to deal with Xiaomi’s waiting period, account binding, or official unlock tool, there is another way. Using MTK Client, you can unlock the bootloader directly by modifying the security configuration on the device.

This method is for advanced users. If you’re already familiar with flashing, boot images, and Magisk, you’ll feel right at home.

Step 1: Set Up MTK Client

Clone the MTK Client repository:

git clone https://github.com/R0rt1z2/mtkclient
cd mtkclient

Install dependencies:

pip install -r requirements.txt

Make sure your device drivers are installed (MediaTek USB / CDC).

Step 2: Boot Phone Into BROM Mode

Power off the Redmi 14C completely
Hold Volume Up + Volume Down
Connect USB cable to PC
Release buttons once detected

MTK Client should now recognize the device.

Step 3: Unlock Bootloader (seccfg Method)

This is the core step. MTK devices use a seccfg partition to control lock state.

Run:

python mtk.py da seccfg unlock

If successful, you’ll see confirmation that the bootloader is now unlocked.

If You Get DA Errors

Some Redmi 14C builds require a custom DA (Download Agent).

python mtk.py --loader custom_da.bin da seccfg unlock

(Replace custom_da.bin with the DA that matches your chipset.)

Step 4: Extract Stock Boot Image

From the official firmware:

Extract boot.img
Copy it to your PC
Transfer it to the phone storage

Step 5: Patch Boot Image With Magisk

Install Magisk on the phone
Open Magisk → Install
Select Patch a file
Choose boot.img
Magisk will generate:

Copy the patched image back to your PC.

Step 6: Flash Patched Boot Image

Now write the patched boot back to the device:

This replaces the stock boot with a rooted one.

Step 7: Reboot Device

The first boot may take longer than usual. This is normal.
