SOLUTION FOUND, ALL PROBLEMS SOLVED :)

Hi, I recently installed Android 4.0.4 to my Galaxy S2. The reason I am asking these questions is because all/most of the documentation written for them seems to be written for a Galaxy S2 with 4.0.3 or below.
Basically, the latest update was bad, made the system look ugly, makes phone signal drop, battery drain, some texts drop, and Silent mode seems to be no different from vibrate mode in that it still vibrates. What I want to do is root my Galaxy S2, backup all of the apps, SMS, MMS, Call logs and their data (So that when I restore the phone, I don't have to start games like Asphalt 6 and Cut The Rope over again) and then install CM9 + Google Apps and restore the apps and their data. Is there an easy way of doing this that's suitable for a first time rooter and flasher?

Thanks so much for any help, Jack :)

Running an unbranded, sim free Galaxy S2 bought from Amazon.
On giffgaff network.
In the UK, so I'm not using LTE or anything like that :)

Root using method 1 from guide in my signature. Then backup all with Titanium Backup.

Ok, I read through it and it seems like it's not too complicated, but when it says "Internal SD Card" does that mean my MicroSD card or something different?

Thanks, Jack

Edit: Also, where do I download the files that it mentions?

No, internal SD card is your internal storage. Your microSD is external as you can take it out

Ok, thanks :)

Also, because the forum wouldn't me add the edit in time, where do I download the files that the guide mentions.

Sorry for asking all these (possibly stupid) questions, I'm just nervous :)

As for backing up apps and games etc....titanium backup. I was advised to use the pro version, will never turn my back on it. As for the rom and root it depends what kernel wnd rom you want to use. My signature has links to a reliable kernel and rom thats based on CM, AOKP and a few others rolled into one, magic config link is also usefull to maximize battery life

Ok, also, is anything likely to go wrong during the rooting process? I'm trying to backup via Kies before doing anything, and Kies keeps failing and telling me to reconnect. I've tried restarting the PC and phone, and it keeps doing it, some I'm wondering whether I should bother backing up with Kies at all.


Thanks, Jack

it's your internal storage (Phone), not the microSD card...

Only thing that will happen when rooting (providing you use a kernel that is trusted, some have emmc cap erase bug, messes things up, luckily i aint had that before) your get a yellow triangle when booting your phone, this can be removed using triangle away app which resets your binary to say it hasnt been tampered with. Aslong as you follow instructions fully, you should be fine as for kies, odin hates it, disable kies or uninstall it from your pc. Backups are always better with titanium, your probably find that your apps are backed up to google but may need to restart games etc where as titanium saves everything so you start from where you left things

Ok, so I decided that I'm going to use Method 1 in Stileth's signature ( http://forum.xda-developers.com/show....php?t=1746794 ) would this apply for that? How dangerous is that method. Also, I can't backup with Titanium before rooting, which was my main concern, as I wanted a backup in case anything went wrong whilst rooting.

Thanks, Jack :)
