Why the J710F EFS File is Unique to Your Device

Unlike the system or cache partitions, the EFS partition is unique to every individual handset. You cannot download a generic "J710F EFS file" from the internet and expect it to work on your phone. Doing so would change your IMEI to someone else's, which is illegal in most countries and can blacklist your device.
