The Solution of Invalid IMEI Problem of Android Smart Phone


Hi!!! How are you? I am fine. Today, I am sharing on another topic for you. The name of the topic is: The Solution of Invalid IMEI Problem of Android Smart Phone.

We set route for many reasons. Either we do custom route flush or if the set bricks, then we do Stock ROM Flush or if the set does not route, then we reset so many rooted and non-rooted devices. (Android in advance of the experts, etc. should not be without.) For doing this work, so many people face a common problem such as Invalid IMEI Problem. According to the experts, after setting routes, the three works must be done: 1. To take IMEI Backup. 2. To give Custom Recovery (Like CWM Recovery) flushes 3. To take Stock ROM Backup. But after setting a route, so many people have forgotten to take IMEI Backup. As a result, Invalid IMEI Problem occurs.

N.B: There are many methods on the net, but I think that this method is simple. My site is non-rooted, so this method is tested, but the rooted users, you can try to do this. This approach is totally safe, I have succeeded by trying this method, so everyone can be assured. This method is fully for expert users and others will try to do at your own risk. Please follow the procedures described in the past, but if the phone of anyone is hurt, then there is no responsible for author.
