if you're asking about the phone data reset, then no. it wont. (beaten to it by ironass)

flashing the rom is the permanent downgrade.

I'm surprised you can easily flash to JB but not have some time to read on how to restore back to a official/stable rom if something terrible happened. That is bad practise... in my personal opinion. Be sure of what you're doing before doing it... you dont want to be a proud owner of an electronic brick.

Hello there

I successfully installed JellyBean on my Galaxy S2 a week ago. The phone worked fine for around a week but now its showing "Not registered on network" error when I am trying to make a phone call but the data is working absolutely fine. I have tried resetting the phone and even installed same Jellybean but still same problem "Not registered on network".

I want to go back to ICS and I have tried #6 (downloaded MD5 and installed using ODIN) but seem there is some issue as the phone is getting stuck on Galaxy logo. and below is the log
