[help sph-l710t]

I need help. I rooted my phone and currently running on Beanstalk rom. But there are some major issues...
Baseboard is UNKNOWN.
Mobile network state is UNKNOWN.
Service state is OUT OF SERVICE.
Mobile network state is DISCONNECTED.
My phone number is UNKNOWN.
MIN is UNKNOWN.
PRL version is UNKNOWN.
MEID is UNKNOWN.
ICCID is UNKNOWN.
I have flashed the efs.img, it was success. But still same problem. Also flashed modem. Still same problem.
I forgot to do a Nandroid backup so now I left with my phone just running on wifi. I don't know what else I can do to fix it. I have posted on Androidforums.com and they don't know the problem either. So I figured I would try here.
***Does anyone have the Nandroid for the T-model? If so, can you send it to me? Please!!
Thanks!

IMEI null and Baseband Unknown

Hi,
I have a Galaxy tab S 10.5 and my UK sim card wont work in it because its saying it has no IMEI and the baseband is "unknown"
I brought this tablet second hand so dont know the full history of it.
Whilst trying to troubleshoot it through it has Lollipop 5.0.2 but the CSC was belonging to Italy (ITV). Before i played, the AP was T805XXU1BOJ1 and the CSC was T805ITV1BOG1
I have used Odin and tried flashing back over the top a UK version of the stock 5.0.2 firmware which was successfull but still the IMEI is null and Baseband unknown. The AP is still T805XXU1BOJ1 and now my CSC is T805BTU1BOI1
Is there anything else i can do please to try and get the IMEI and baseband back so i can use it for cellular as well as wifi?
Thankyou
