Lost IMEI need help

Dear Friend,
anyone of you have G-PRO especially those with non-international version should backup your IMEI before trying to upload any new ROM. To back up, please download the tool below (I took it from M_Tool of someone I don't remember) and run it from a CMD Administrator windowl; you should also have your phone connected with debug mode, rooted phone and adb.exe shall be in PATH.
I bricked up my phone with losing the IMEI, i could restore partly now but could not connect to 3G network (only GSM). The reason was that my back up lacking of some files. So anyone have G-PRO F240L or a 988 please be so kind to give me a version of your backup. I need that to make my phone back to a smartphone.
Regards,
Quang

Have you tried taking your phone to a service shop? I believe that would be your best shot. They might restore it in a matter of minutes...
You might have better luck choosing an independent store rather than a licensed one.

some times its a imei issue. in my case it was sim tray issue. i had to change the sim tray from service center only.
have you taken backup before flashing new rom?
if yes, then restore the EFS folder from CWM or TWRP backup

Did you ever get this? I've read in other threads that there is one on this site, but I haven't been able to find it. My imei got wiped, so I re-input it, but I still can't connect to AT&T. I read that others had this problem and used an AT&T qcn file to repair their phone.

There's an at&t qcn file in this thread, where the IMEI has been removed. I used this mod and can attest the qcn file is good. http://forum.xda-developers.com/showthread.php?t=2068041
