I know of CleanROM and the Lean Kernel that comes with it. My buddy is able to get the most time out of his and he is a heavy user. I used to only be able to get a day out of the AOKP as well, however after I installed Screen Filter it helped out since the screen brightness is notorious for destroying battery life. With Screen Filter enabled my battery usage for the screen dropped in about half if not more and the majority of my battery usage at that point became cell standby. I can squeeze two days out of my phone with the stock battery, but I don't have reception in my office at work so I spend a good chunk of the day without reception unless I go outside which I do quite often.

I had gone from AOKP to Liquid Smooth and that ROM has a lot of kinks to workout in my opinion. AOKP is the more stable ROM.

 

I dont have any signal at Caltrans in the IT Dept.... ANYWHERE else in the building is fine tho

 

Ironic much? After going with the s3 I decided to mod my own radios slightly so its a hybrid kind of like how galaxy nexus has it. Now I get reception almost every where

 

How easy is it to root an S3? I don't want to brick mine. All I want to do is turn off TouchWiz and run vanilla Android 4.1.2 or higher ad have NFC and Google Wallet access. Nothing fancy ( for now )

Specs: Andriod 4.1.1 ATT

EASY lol, also keep in mind you will need to unlock the bootloader as well. This toolkit takes care of everything for you

 

its damn near impossible to brick any phone that can utilize ODIN, hell, i've unbricked phones using ODIN.

 

unless you run into the famous eMMC brick so be sure not to format your partition aka format data/system if this bug persists in your phone. You can see if you have this bug using chainfire's app on the market.

 

Thanks. I saw exactly what I want to do, LiquidSmooth 4.2.2. Now to do this when I get home in the morning

Good to know

 

Ya the one place I spend the majority of my time there and I get no reception hahaha

 

Root - successful. Dont even know what I was stressing about. So far just installed Debloat, Busybox, and Tibu. Now to figure out how to rom it

 

Install twrp its the best IMHO. Cwr is good too but I think twrp is nice. Before installing a ROM clear cache/delvik 3x in twrp as well as install any upgraded radios for the ROM.

 

Cache is cleared. I was looking at this and it says I need a clockwork compatible kernel for it to work https://play.google.com/store/apps/d...9tbWFuYWdlciJd

I used this method to root

Edit: OH **** SON!!! Flashed Build 6 of http://forum.xda-developers.com/show...949025&page=41

Edit 2: Oh **** I'm stuck on the Boot animation.

Edit 3: ****......... It's alive.....

 

Go under advanced settings and you can installed open script recovery (twrp) its much more user friendly IMHO and will make it so you can't brick a thing haha. I'm a ROM developer for the sg3vzw and even I bricked a phone doing something stupid on my galaxy nexus which caused the emmc brick (fixable but not worth the effort). Also if you want something close to stock ROM I personally run jelly beans build 14 and you can customize it to anything you want with the aroma installer. I've done my own ROMs for my galaxy nexus and did one for the sg3 and his is by far the smoothest I have tested so far. Build 15 is dropping soon I suggest you try it out.. Its multi carrier

 

Whenever i get ready to flash anything I READ READ READ and ask questions if i have any. I have gotten boot loop before and a softbrick and its never fun and can be really stressful.

 

Always a golden rule, if you are unsure about something ASK.
