I have my device samsung s3 galaxy.
Instead of the original imei erased and written in a different IMEI.
I want to install a different rom or custom rom now I want to install the network going. we have to throw again imei with spt box. The most robust way to back up efs file? original or subsequently thrown can make the device can erase imei?
I have an unlocked AT&T note2 (firmware i317UCALJ2) with IMEI on the phone different from the one registered on the back.Got some assurance from Samsung that IMEI on the back panel is genuine and clean. I heard from a lot of forums that sometimes flashing a device might corrupt an IMEI( "null", all '0's etc.) but IMEI on my phone(*#06#) is like "35700.." .
