Yesterday i upgrade infinix hot note X551 to android lollipop 5.1, After successful upgrading i reboot the device and i notice invalid imei which mean the phone miss it imei number and it will not work properly with networks providers.

As we all knows imei is an identity to any device, so without imei your device can not be recognize or detected by any of the network service providers, and due to that you can no longer make calls, access internet service and any thing that required network. But you can only access network via WIFI.

The only way out to this issue is to fixed the invalid imei by replacing it with a valid imei. A lot of people says you have to root the device before you can able to fixed the imei which is not true because  i fixed the invalid within a minute without rooting my device.

  20. Is not working on my phone it keep saying this command is not allowed in userbuild

  21. IMEI is writen on the box,or the baterai, you can get your imei back,it doesnt mean you will get the mobile network, it will only the imei appear, not for normal mobile network that you need to make an call or internet etc. so this is unusefull, the problem is not imei, its no service providers that can read your simcard, its need to flash for anyone who get their imei back but not for the mobile network.
