🛠️ Step by Step IMEI Repair Process#

1️⃣ Step: Installing Required Tools#

First, download the mtk_imei tool from GitHub:

git clone https://github.com/timjosten/mtk_imei.git
cd mtk_imei

2️⃣ Step: Preparing Chip ID and Config File#

Get your device's chip ID:

adb shell getprop ro.boot.chipid

Sample output:

0x1234abcd5678ef90123456789abcdef0

Create config.txt file in mtk_imei folder in JSON format:

{
  "patch_cert": 0,
  "device": "begonia",
  "kernel": "4.14.186",
  "chip_id": "0x1234abcd5678ef90123456789abcdef0",
  "imei_1": "123456789012345",
  "imei_2": "543210987654321",
  "wifi_mac": "001122334455",
  "bt_mac": "66778899aabb"
}

To get Wi-Fi and Bluetooth MAC addresses:

adb shell cat /sys/class/net/wlan0/address
adb shell cat /sys/class/bluetooth/hci0/address

Check file format:

file config.txt

If CRLF exists, correct it:

sed -i 's/\r$//' config.txt

3️⃣ Step: Creating IMEI Repair Package#

Create the flashable .zip file by running the mtk_imei.sh script:

./mtk_imei.sh

When successful, you will get the following output:

MTK IMEI patcher by timjosten
Success!

The imei_repair-<device>-<kernel>.zip file will be created in the out/ folder.

4️⃣ Step: Taking NVRAM and NVDATA Backup#

Turn on your phone in TWRP Recovery mode:

1. Go to Backup menu
2. Select NVRAM and NVDATA partitions
3. Save the backup to SD card or computer

5️⃣ Step: Flashing IMEI Repair Zip File#

Send the IMEI repair file to the phone:

adb push out/imei_repair-begonia-4.14.186.zip /sdcard/

Turn on the phone in TWRP mode:

1. Go to Install menu
2. Select imei_repair-*.zip file
3. Load by Swipe to confirm flash
4. After the process is complete, restart with Reboot > Recovery

6️⃣ Step: Verifying IMEI#

After the phone is turned on:

• Check from Settings > About Phone > IMEI
• Or enter *#06# code on phone keypad

Make sure the IMEI numbers are displayed correctly.
