Rooted == Titanum Backup, so install that and then can restore apps etc piece of piss
Not too sure as it is worth it. I know that the ITaly 3G has had a R2 and know a R2A, but this is for the 3G more than anything.
TBH I have updated R1A on NZ tab and I can't see a difference.
Since you have root you could allways change back, simple as.

It won't work. I tried that method. Your Imei is fine you said but i'm 100% sure your Serial Number isn't.
You can follow this guide.

No u cant.
Its against rules discussing such thing
Other than being illegal.
Every efs containes imei s/n number mac adress keys between many other unique things.
You would be cloning a phone.

Easy to fix man!
Install any rom that gives you your original IMEI (don't worry 'bout "not registered on network" message)
Root your smartphone and install CWM
Install (by cwm) latest kernel & modem of this page: "THIS PAGE"
Your welcome

Sorry , where i can find this model forum ? or a solution for the same case ?
I think this is normally caused by a corrupted EFS partition, which can be caused by downgrading to a ROM that uses an earlier EFS version. Is this likely in your case? If so try searching "corrupted EFS" for a solution.

[Q] hardware micro coding of IMei

Hello all,
Do someone can tell me if the micro coding (hardware or ROM) of IMEI is something recent, or if the latest ANdroid version use something that existed yet in 2012 ?
Thank you
Own a I9300 oct 2012 ....
EFS format changed at firmware EMG4.

Thank you.
Does it mean that if I change from 4.1.1 to 4.2 (or 4.3 , anything using EMG4 possible with the I9300) that will give a chance to the proper EFS to be written , or is it out of question IYO ?
Loss of IMEI while trying to repair the phone that lost wifi then soft bricked some time later. of course I have all SN at hand.
If my IMEI is somewhere "hard coded" it is worth for me to try things but if not I will need the help from some repair shop.
Best regards

IMEI Changed , No Network

Friends I'm in a trouble.
I was using Cynogenmod 11 and that time my Network was fine ... as soon as I restored my stock Rom (4.1.2) , I lost my network ... when I make calls ... a pop-up message appears "Not Registered on Network" . Manually Selecting the network also doesn't work. In Phone status ... it show NO SERVICE
My Previous IMEI Number was 353**************** and now it has changed to 0049*****************
I'm not able to make calls or recieve it ... PLEASE HELP
Hello,
You must install stock rom with Odin. It is easy and you find steps if you search on google.
