Have you lost your IMEI of Huawei devices in changing the firmware or in the unlocking process. This post will help you in repairing of IMEI / or also you can change the IMEI if you have data lock code.

IMEI is a unique identification of any phones / modems / routers. Without IMEI you can not connect to the internet (especially in India, may in another country too). IMEI remains in a standard format of 15 digits. If a device lost the IMEI, it will show 000000000000000. Means, if IMEI is missing from your device, it remains in “half-dead” state. Meaning it can be repaired and re-used without any problem.

In this post, we will share the details about how to change / repair IMEI of Huawei V4 devices, for instance, E5573, E5577, E3372h etc.

How to change/repair IMEI of Huawei V4 devices (E5573, E3372h etc)?
