Before you start the rooting, flashing and tweaking stuff, the very first thing you should do once you get your device is, you must backup the EFS partition of your device. Downgrading the firmware on your device, flashing a wrong file with an invalid kernel or a wrong bootloader, or flashing any file that is not supported by your device can result in messing up your EFS. EFS partition includes all the information of your device’s radio and modem, the imei number is written on this partition and if some how you mess up this partition, you will end up getting a generic IMEI or a you will simply get a nulled IMEI. As a result, your device will become a gadget without a phone feature. You won’t be able to make any calls, you won’t be able to send any sms messages and same goes for other connectivity parameters on your device. You may read all about EFS here.
