how to fix null or unknown IMEI on a Marshmallow Android phone

If you notice that your phone’s network bars suddenly remain empty for a long period of time despite the phone still being able to detect your SIM cards and identify their networks correctly then it just might be a Null /Unknown IMEI at work. This issue often occurs after flashing your phone but could (on rare occasions) occur randomly. We already created a detailed guide on how to resolve this at https://forum.hovatek.com/thread-116.html but some Android 6 (Marshmallow) users have complained about some of the methods there not working for them. This guide will put that to rest.
