Question Updating from samsung 4.1.2 to slimbean 4.2.2

In the past i tried to update from 4.1.2 to 4.3 and my imei has changed to 0049
I understan its related to the new modem.

Now i have a brand new s3 and i want to go back to slimbean 4.2.2
Is it dangerous to update from 4.1.2 to SB 4.2.2 ?
Is there any chance that my imei will change again or its using the old modem?

Thanks.

It wont normally mess up your IMEI. It will on the other hand change your efs to the newer efs v2. Which should be no problem if you backup your IMEI in the first place and as all XXEMG4 or beyond use efs v2 your fine.

You should read this thread again which was already posted by JJegan. Everything is explained there.
