Is it possible to backup the phone before root?
So if I have to return the phone I can restore the radio and rom and kernel from odin?
No you can't. But you can check if you can find your current firmware here.
The only way is to root then backup but you have a rooted phone as backup which voids warranty and in that case you would be better downloading a stock Samsung rom .
Installing that will remove root .

If I root my device will I lose my apps,widgets,contacts,settings,etc?
Not at all.
You will not loose anything.
Just got permission to access System Files.

Kernel no custom rom no if its no wipe but yes if its a wipe rom .
But only a fool does not have a full backup .
Point of note custom rom or root or rooted kernel all invalidate warranty and require restore to stock and resetting custom rom counter to zero.

Hi,
I have stock firmware with root acess and CWM. I plan to do a backup of it and install a custom ROM. Say later I would like to go back to the stock firmware which I have already backed up, will that be a problem? Or do I need to do something special?
Make backup using CWM and you will be able to get back whenever you want. But if you want warranty back, the rom flash counters must be set to zero.
Google "triangle away" program.
As above and any CWM backup requires stock kernel to replaced rooted kernel after.
Simple is use Triangle Away then flash a stock rom.

I have firmware XXBLFB (rooted) and have installed a custom kernel which I no longer wish to use. I would like to restore the stock kernel which came with this firmware release. I know I could just ODIN the BLFB firmware back and then re-root but it seems a long way to go. Is ther a way to use mobile ODIN with the firmware file to install Kernel only and retain root?
Thanks.
(Yes, you're right. I SHOULD have done a nandroid backup first!)
I'm rooted with CF-Auto-Root on a stock ROM. I want to unroot so that I can safely re-root with msskip's Toolkit. How do I get there? I don't care if I have to totally wipe my phone. I have the latest stock ROM from Samsung's web site if needed.
Flash a stock rom via ODIN wipes root .
