Owners of the newest Samsung Galaxy Note 2 can now back up the EFS partition on their devices using a one-click tool that will allow both backup and restore when required. The EFS partition can be wiped when users flash custom ROMs on their machines. This might remove vital IMEI data and cripple all network functions.
To avoid such issues, Galaxy Note 2 users can install the one-click EFS Backup tool. IBTimes UK advises users to proceed at their own risk. We will not be held responsible for any damages that could occur on your Galaxy Note 2.
