2 cents more:

This will work only if HW is OK ( in case of just damaged EFS ).
In current releases of Z3x tool there is no need to write any EFS dump at begining, just put phone in download mode and make Reset EFS from repair operations - this will do the job.
It's better to use 4.1.2 firmwares ( root it, please, after EFS reset and before IMEI and SN repair, for example with Impactor ) with Z3x tool. This will guarantee 100% OK sw inside the phone ( can be updated in future without risk of surprices ) after repair of IMEI and SN.
