Help Before Installing Custom Rom

Hello !

This is my first android phone so i am a total newbie.

I have upgraded my Galaxy Ace 2 GT-I8160 to stock JB 4.1.2 (kies).
Now my phone has become slow and i would like to try a custom rom i that maybe could help.

I would like to try Cyaneogenmod 10.1 by Team Canjica.

I have learned that i dont have to root because CM has root-access.

Correct me if i am wrong but the first step would be to make a temporary cwm [JB] CWM Recovery 6 - xda-developers and then install CM ?

Many Thanks guys !

Well ... you don't have to root before installing a new ROM because it's the ROM that gets rooted, and rooting a ROM you're about to overwrite is a waste of time.

Quite seriously? The first step would be to open a web browser and spend a few weeks reading about Android, ROMS, rooting and all the rest that goes into it.

To install a ROM, you do what the ROM developers tell you to do in the instructions - use Odin, use adb, use CWM. Each version of each ROM (and there's more than a single version of each one) is written to be installed in a different way. For instance, Cyanogen (I haven't used it in a couple of years, so I'm guessing) may have a version that downloads the new version and installs it. Then again, installing Cyanogen on an unmodified Ace may require that you Odin CWM into it and use CWM to flash Cyanogen. (Just guessing here, again.)

I really urge you to learn what you're doing before you do it - or you could end up being told by your carrier that since you installed unapproved software, they won't deal with your (now dead) phone.

Besides, you can do a lot of what Cyanogen gives you by just installing apps. What are hey using now - ADW launcher? You can install that from the Play store. Gives the phone a whole new look. And it's not "unapproved".

CWM is nice. But bring a phone in for repair with CWM on it and they'll ask you which phone you want to buy.
 
Thanks for your reply.

I have read a lot about rooting etc. but maybe i should read more.

I am just so dissapointed with the phone and i should have never updated it. Afterwards it became slow, and even the internet became slow and that bothers me most when videos buffers constantly.
I hadnt this problem with GB but i wouldnt like to downgrade back either when i am used to JB.

One reason it may be slow is that hardware designed to run GB isn't powerful or fast enough to run JB. It's like trying to run Windows 8 on a computer designed to run Win2K. Run GB, with the GB enhancements that makes it look like what you want, and save your money for a real JB (or KK) phone.
