Hi everyone,

What would be the general steps to take to update to 4.3 from 4.0.4. I messed up my phone a while back updating (no signal basically, no calls, etc, yeah... my fault for not reading...) so I had to take it to a shop. They downgraded to 4.0.4 and I'm not even sure my IMEI is the same...

Anyways, how can I upgrade and not lose their "fix". I remember reading about backing up my modem, flashing then reflashing my modem. Would that be enough?

Is there any backups that I can do that will create an "image" of the phone that I can safely flash back to in case anything goes wrong?

I currently have SuperSu and I think CWM (but an older version).

Any help would be appreciated!

Backup your efs folder, then make a nandroid of your rom. You will end up with no network after upgrade, try patched modern and kernel but there is no guarantee.

Search and read for the hundreds of other people who did the same thing.

Hmm, alright.

I'll make an EFS back up and the nandroid of my ROM just in case anyways. Thanks.

take more than one EFS in many methods rather than single one.
