Upgrading rooted Samsung Galaxy S2 to ics via kies

[budvegas]

Hi everyone

I have a rooted samsung galaxy s2. Now the ICS update is available via Kies.

My question is:

If I do this update, will my phone still be rooted?

The reason I ask is I have backup pro which (because I am rooted) backups all apps and data and I want to be able to restore.

Thanks in advance.

Bud

Hi Bud,

I also updated my kies and received an update with my rooted Samsung Galaxy S2 plugged in.

I would prefer to upgrade via Kies then go through ODIN if possible.

Did you end up unrooting or upgrading via Kies>

I followed a different method. It will cost you some small amount of money though (can't remember .. like $2.99).

Download the Mobile odin pro app from play, then download the correct ICS update as described in the first and second post of this page:

Finally unzip the file into a *folder* on your android device and invoke the mobile odin. Choose "preserve root" or something like that when you install the image.. It worked flawlessly on my Galaxy S2 i9100

Instructions for mobile odin are here

It is important to take a nandroid backup before you start, so you can go back to GB if you decide ICS is not for you.. Unfortunately I forgot that part

Anyway till now Im happy with ICS.
