You need efs pro if you had done a backup of several qualcomm radio modem earlier. Read more. http://forum.xda-developers.com/gala...ional-t1308546
Then you need QPST software, also it is from qualcomm. It is a diagnostic tool but you have to activate the com-port within your phone with some tricks or usean apk called phoneutils.apk.
If you search you'll find. Me to had corrupt imei when I tried som things inside my phone, for example I deleted the NV-build (the golden build) and thats I it happens. I tried to unlock it. In this forum XDA, it is not aloud to tell you how.
In short you have to be
installed free version of busybox.apk.
installed software on your pc (efs pro and qpst)
and phone-mode in usb-modem-diagnostic. http://forum.xda-developers.com/show...626638&page=11
You probably have lte so it is qualcomm. But don't trust me, search by your self. Do you have the original backup or the original imei-number left in the box you bought?
I made a restore from my friends backup and putted back the imei when the com-port was connected, With Efs-Pro manager in the link I wrote.
Dont forget to thank me if I helped a little, I haven't checked if you have qualcomm (4g) or exynos chipset (SoC) systemOnChip
