get cellinfo with adb shell
Both of these worked for me:

Option1: grep AT command for cell info

$&gt; adb logcat -b radio | grep ": +CREG:" 
D/AT      (  873): +CREG: 2,1,"2444","0FA2A694",6
D/AT      (  873): +CREG: 2,1,"2444","0FA2A694",6
D/AT      (  873): +CREG: 2,1,"2444","0FA2A694",6


[1] phone is registered with the network 
[2444] hex : Location Area Code (LAC) 
[0FA2A694] hex : Cell Id (cid).

Option 2 : you can grep "cid" from logact -b radio you should get it this. note it is decimal this time.

$&gt; adb logcat -b radio | grep "cid"
D/use-Rlog/RLOG-RIL( 9193): cid: 262317716
D/use-Rlog/RLOG-RIL( 9193): cid: 262317716
D/use-Rlog/RLOG-RIL( 9193): cid: 262317716




Option1 is my personal preference. hope that helps.
