Help Firmware update helping hand

[lavellep]

Hi there,

I'm running 2.3.3 on my S2 XXKE7 and thought it may be good to update it to 2.3.6 to benefit from battery life improvements.
I was going to download this one: XWKK2 from XDA forums.
I'm rooted and have my phone backed up on the SD card with Titanium.

Anyway, I was just wanting to check if this would work? I'm a bit nervous about bricking my phone and no matter how much I read XDA and the guides, they may as well be in Japanese for all the sense I can make of them.

Basically, I have a sim free UK non-branded white S2 and I want to update it to the latest software with ODIN. Do I have to go for a specific firmware or will any work? Will I lose everything and have to restore from a backup or will it just turn on, updated, but with everything in tact? And do I have to then muck about with updating kernels and base bands etc (which I don't have the foggiest what they are really - let alone how to update them! Ha ha).

I'm sorry this is probably a really amateur question but any help for a slightly thick person would be greatly appreciated. And I'm sure Santa would look down on you kindly!!

Many thanks ;-)

The XWKK2 firmware will be fine. It should be a no-wipe update but a backup is always a sensible precaution. You'll lose root so will have to reroot after the update - a KK2 CF-Root is available to do the job. No need to change the baseband (modem) from the one installed with the update.
