Network signal gone after rooting

I've got a problem. My younger brother attempted to root his i9305. When he rebooted his phone, everything was fine but there was ao network signal. Went to setting to check what network he was on nothing came on. Any idea what happened??? I'm suspecting it has been sim locked. But it doesn't have that sim lock thingy. .

I think you have lost your imei too.

Do you have a circle with a line through it at the right hand side of the notification bar? No imei in the about device settings?
If so, he has lost his efs.......
There is a walkthrough in the android development section of the i9305.
It's titled "lost imei / nv data restore" or something along those lines.
It happened to me when i had nfi what i was doing. I flashed a i9300 rom instead of a i9305 lolz. Your bro prob did the same. Hope this helps!

You need to download and flash the param binary in the sticky guide thread. Near the bottom of the first post.

[Q] Internet connection vs calls

Hey guys, I was wondering why my 2G/3G connection goes down while I'm making a call, on my previous devices it wouldn't happen and it's kind of annoying since I want both of those things to work at the same time. Any suggestions? :fingers-crossed:

What phone did you havr before?

Your question is a bit confusing.. Are you trying to tether (send internet from your phone to your pc)? If so, look for WiFi tethering.

Also not sure of the question but I'll take a crack at it. If you're running a tether, make sure your network allows it or you are rooted with an app that supports it.
If you're running a hotspot off of your computer, make sure it is up and running and broadcasting the ssid

Galaxy not gt n7000 switches on itself

Hi my note gt n70000 switches on itself every hour strange I'm on a custom rom ultimate jelly bean is this causing this problem
Sent from my GT-N7000 using xda premium

I don't think so. I was using ultimate rom, never had such problem. I don't think anybody in the ultimate rom thread reported such thing. Either reflash the rom or try another rom. Else could be hardware problem. Clean copper points in the phone and battery.

There's probably an app that tries to connect to internet but because of unavailability of interent connection it cause the screen to awake use better battery stats to find out the culprit and then uninstall it

Do you use same network as when you installed your system.
I met this issue when I switched to a new router. Nothing I did would resolve it so I installed the system all over again while on the new router and voila..
