IMEI repair
 

I just got an S2 (kinda upgrading/downgrading from my s4 (get to that later) i wanted to root it and unlock it so I can use it on my plan. In the process of rooting and installing another rom. (Like the guide told me) I lost cell service (Circle with the Line)

When I dial *#06# at first it gives me the dummy IMEI 0044999....
Ive repaired it and was able to match it to the default one that matches the sticker behind the battery, But still no service. for the last few days I've been looking up guides and trying everything I can think of. Keep coming across the Z3X box that could repair it. I don't have too much money since i'm going to school full time but I was wondering if I can pay to send it to someone to fix it for me. (Same IMEI)

The reason I want to use this phone instead of my newer s4 is because it was my sisters, she past away a month ago. unfortunately she did not have that much money also and she did not have that much stuff for everyone to use as a keep sake. I would love to use it as a daily driver if at all possible.

Any help would be appreciated
Thanks in advance
