[houz]

First of all,hi,i'm Gabriel and i'm new in here,i got my SGA 2 weeks ago and i'm really loving the phone..I just rooted my phone and i'm thinking about installing a ROM in it,this one specifically [ROM][UNOFFICIAL]CyanogenMod-7.2.0-by-FAT-KANG[UPDATE 19.02.2012] - xda-developers

But i don't know how to,and i'm a real noob when it comes to this stuff,and also if there's a tutorial about this i'm sorry because searched everywhere for one but i didn't find any.

Please help me, how can i install this rom into my phone,and i have 1 dowd,if i install it and i don't like it,is there a way to unnistall?

Oh and if someone can point me to a better rom i'd apreciate it,i'm looking for a rom that doesn't drain so much battery,it's good looking and it giver a better performance in games n stuff =p
Thanks.

[TUTORIAL] How to upgrade, root, flash Recovery & Custom ROM Samsung Galaxy Ace S5830 - xda-developers

You need to do step G and H to flash this rom.
If you want to revert to your stock firmware, go to step C.


Dude if you want cynogenmod, your gonna have to compromise its awesome features with a little battery, else just stick with stock based roms...they have the better battery backups.
