Phone does not connect to Network (started after being stuck at samsung logo)

Hi everyone,

I rooted my note and was using Jon ROM V3 for the last 3 months. Never had any malicious apps and my phone was working as usual.

Yesterday I took my phone and see that it is stuck at Samsung logo (an hour ago it was working fine). Tried reset and re-flashed ROM but no luck.

Later through download mode i flashed Official Indian Firmware(I live in India). Now I by passed the logo screen and the phone shows full signal bars but not able to connect to carrier network.

(tried all basic work out like removing battery/sim and re-inserting to phone and boot up)

I pressed power key and it did not show the power menu , it directly switched off mobile.

I rooted again with Philz kernel and flashed JON ROM. Still i see that my phone is not able to connect to any network. Also I observe that even here on this ROM when i press power key it directly turns off.

This is weird. I thought my IMEI was wiped off but im lucky to see that its still there.

I need your help. Im without my phone for the last 2 days now.
