[Q] Thinking about Rooting

Hello XDA community!
After doing lots of reading about rooting and installing ROMs, I have a few questions:
1. By rooting your phone, or installing a new ROM, does it touch upon/delete the storage and installed apps, or does it leave those alone? (Like a "repair" installation of Windows)
2. If needed, will the use of Ti Backup to reinstall my storage/apps affect the outcome of the root?
Lastly, I was wondering about which method would be the most simple. I know this is a very subjective question, and there will be lots of opinions, but what I'm mainly looking for is a stable 2.3.6+ with the newest wifi modem capabilities, and CIQ removed.
Thanks much,
Haz

Rooting does not affect apps. A custom rom however does as most of the bloatware will most likely be removed.
Whitehawkx just released his updated rom Juggernaut to the latest build. I would go that route if your looking for a good rom.

Ok, so rooting doesn't affect apps. Does it affect any local/USB storage?
The Juggernaut "4.0" looks promising, but my only concern is that there is no mention of whether CIQ is removed or not.

Rooting doesn't effect storage either and I am sure ciq is disabled in that rom.

Hmm, nothing specific in the changelog regarding CIQ...
Out of curiosity, which setup are you using?
Sent from my SGH-T989

It does not mention CIQ because CIQ is disabled in the Kernel, and the ROM uses THIS kernel , which has CIQ removed ...

If your rooted you can use clockwork to do a full system backup before you do anything.
Titanium can backup the app data. You may have to download the apps again. Not a big deal.....
Any ROM you flash follow the instructions to the letter on how to flash.
Good Luck

There are countless Youtube videos walking you through the entire process. It's not as difficult as you may think and after awhile you won't give it a second thought to flash a new ROM or Kernel. It is not without risk however but if you mess something up there are instructions for that too and help when needed. Watch a few videos and when you're comfortable, give it a try.

I'm new to Android and I have to say that as long as you do your research and follow instructions you won't have a problem. I'm running the new juggernaut. Wifi calling is working quite well. Remember to flash the new modem

First of all, yes you should root! You'll love your phone twice as much. Not to diss any guides here but the video on this page made me most comfortable to root mine.

Just don't download roms from there they are out dated lol

Thanks everyone, I'll do some more research.
I think I'll test out Juggernaut soon!
Sent from my SGH-T989

My wife gave me mine on Friday night (late anniversary from Tues/early Christmas), I rooted it and flashed Juggernaut 4.0 this morning (while she was still sleep so I wouldn't hear any complaints, lol). No need for fear if you do your research and diligently follow the steps.

How's the battery life on juggernaut?
I noticed it overclocks the phone, which will most likely affect it.
>>Sent from my Samsung T989

So i'm deciding to use a route that is as stock 2.3.6 as possible, plus wifi, minus CIQ. Mr. X's looks promising.
Regarding the modem, how do I know if mine is already up to date? My phone is already updated to TMO's 2.3.6 OTA update

I'm using juggernaut and I like it. The power widget in the notification bar is much better then the stock one.
It's overclocked by default but you can turn it down. With juggernaut, you can download "fauxclock" and underclock the max. A suggestion I'd like to make is use that same app and undervolt it by -25 mV. Undervolting will prolong your battery life even more.

Regarding ODIN
Question:
In the Odin3-v.185 download in Allgamer's How To Root sticky, I noticed there is a UVKID.tar
Will this be an issue since my phone already has UVKL1?

All you should need is the recovery tar, and the superuser zip to use in CWM after you install the recovery ... You will flash your new rom from CWM

Some quick help please

Ive been gone for a really long time... so I forgot a few things, ok so maybe a lot....
I want to go from ec05 to EI22 on my epic that I use daily... and want a better stable rom so two questions: -
Whats a good stable EI22 rom?
Do I have to install a new kernel compatible with this modem?

I have had success with Legendary 2.2, it's excellent.
http://forum.xda-developers.com/showthread.php?t=1339217
I also highly recommend the ICS theme here:

I believe you will need to update your modem, modem flashing instructions can be found here:

You don't have to update the modem... modems are independent from the roms... and if you install an ei22 custom rom it will come with an ei22 kernel... all of these things can be found by searching the development thread...

Thanks guys I just needed a little nudge in the right direction.. I appreciate it.

Also note that all Epic ROMs are good and stable. Every phone is different so what works for someone may not work for you so questions like "what's the best ROM" don't apply here. You just have to grab one of the top 10 listed in Development, read some of the thread and flash.

uh, yes. But really take some time to go through and read through the stickies and how tos.
And especially read any developers Original Post instructions on flashing.
Agat, chris41g and rujelus22 have really gone out of their way to build safe kernels/recoveries.
Seriously take some time to read all the way through the posts and you will find loads of information. AND use the search button!

How to get custom recovery?

Hi guys. I know this is probably a stupid question, but I would love to get a recovery on my phone. I'm coming from the evo3d which as super easy to work with. Right more I'm on fk23 I believe it's called through Odin. Really want to try cm10
Sent from my SPH-D710 using xda app-developers app

Get mobile odin and flash the el 26 kernel. Really simple
Before you boot cm 10 don't forget to flash an ics or gb modem first in the same time of flashing the Rom
Sent from my SPH-D710 using xda app-developers app

Best thing to to would be to read the stickies and how tos. And then read them again. Improperly rooting and addding a custom kernel (Recovery is part of the kernel on this phone!) can brick your device!
Not saying this to be a smart ass. Really it's that important; read the stickies, wikis and how tos. And once you've done that you will surely enjoy this phone.
Then read through the ROM OP you wish to put on your phone and read the the following posts - all of them.
You will save a whole lot of frustration and get 99% of your questions answered before you go and ask.
You don't quite say how you got to FK23 and what version - I assume you used PC Odin and via the One-Click Stock Rooted method. If that's the case you can, as the previous poster suggested get Mobile Odin (via playstore - my recommendation to support the dev, or go to the devs post and download the xda only app and kernel part there) and flash the EL26 CWM kernel that way. Or you could even use the One-Click Kernel method rwilco12 has them all here http://forum.xda-developers.com/showthread.php?t=1662295 or the 'Direct boot to safe recovery - CM team has info here http://e4gtcm.blogspot.com/p/cm9-install-guide.html
Either way, and espeically with Cyanogen builds follow the install directions - EXACTLY or you'll be making an expensive paperweight.
Good luck have fun.

Cool, thanks for the quick replies guys! I saw a FK23 packed with AGAT recovery floating somewhere, my question was, if I flash that with Odin, is that firmware compatible with cm10? Or Miuiv4.1? Or any rom for that matter if it doesn't specifically say built on fk23?
And so only the ICS kernel will work on those roms, eventhough they are JB? I thought I read somewhere that modems and kernels werent backwards compatible. Appreciate the quick responses, I'm not a total noob I've flashed and rooted lot of other phones, just got these phones in the mail wednesday though.

DO NOT use the TW kernel repacks on CM builds. That is a brick waiting to happen.
Modems that is another story. JB modems are needed for JB TW builds but some have been able to use older ones, most notebly on the AOSP ROMs.
My best advice stands read through the OP of the ROM you are wishing to use then read through the entire followup posts. The CM team golks suggests EL29 direct boot or EL26 'safe recovery' and then using the kernel supplied by the ROM - CM10 kernel. The Miui also has the same explicit instructions. I'd heed them. But the choice is yours
search is your friend.

Thank you leaderbuilder, I almost bricked my wife's phone twice. I got it fixed, but I just asked in another thread on some advice on what to study up on & I click here & read your post. Heading off to the stickies am I. Thanks again.

New to the club

So I am going to be leaving the HTC Sensation 4G, and considering the GS4 is going to be pretty much like the GS3 (and GS3 are getting GS4 updates) I went ahead and ordered mine just now! Should be shipping sometime this week!
So.. I was running CM10.1 AOSP 4.2.2 Jellybean Kang on my Sensation, I am currently browsing all the Roms available now, what do you all suggest which Rom would be awesome and why? I am all about Battery and Multitasking.

It really depends mate. Thing is if I had wanted vanilla android or aokp I would've bought the nexus device but I chose S3 because of all the extra TouchWiz features as well. I'm running latest version of MIUI and it works perfectly but I know sooner or later I'll go back to using stock based rom. I would suggest sticking with Sammy based roms from the likes of Omega roms and Android Revolution HD, especially if you want some of the features from the S4.
Also reason I suggest the 2 roms above is because they are constantly updated and have active support from the community.

Alright cool cool, would be nice if I had someone to help me root it also once I receive the phone.
edit looked up rooting methods they are MAD EASY WOW!

TW is overrated and looks like a ridiculous cartoon IMO, and all the S-whatever features are just gimmicks right now, though some people love it.
If you loved CM 10.1, its on our phones only official right now the nightlies are a little unstable since the upgrade to the 3.4 Linux kernel but they are working the bugs out. 10.1 M2 will be most stable. No learning curve that way
Battery life is unbelievable with Ktoonsez kernel. 3/14 version works with M2. Take a look at the thread, its got some good info on the governor, I/O scheduler, undervolt, and other settings.
And with our phones, the 2GB ram and fast CPU, its no problem for multitasking. I even ran my phone at 1.02Ghz and it still responded just fine with all sorts of stuff open.

I agree I dislike Touch Wiz I loved CyanogenMod since his G1 days lol, so I think I may take a look at that. Although This Smooth Liquid looks pretty interesting.

I like the PAC-Man ROM and using the Ktoonsez kernel he released today.

Look into sons of android ROM too. Insane battery life.

Once I get my device it's between PAC-Man or Liquid Smooth, if those two aren't good then CM or a stable MIUI (if there is one available for this phone)

Otterbox always good. Look in accessory thread they review and suggest everything in one thread. I use twrp... And flash through Odin.. Easiest for me and convenient
Oh and I found it much easier to root at 4.0,4. Also you can Odin flash using root 66 which come prerooted

I started with CWM, but after switching to TWRP I wouldn't go back.
I used the Root66 method to root the phone - and have used it show a friend how to root their phone and used it to return to stock rooted and get the latest update. Never had an issue, I think it's pretty easy.
I used Wicked for a bit and might go back - I am just a noob and have to work out some issues I had in transferring things over first.
Not sure about screen protectors - mine had one on it when I bought it on eBay and it was so good I've just left it. I just have a $3 TPU and silicone bumper on it and a skin - protects from scratches at least. I've dropped it once or twice with no issue, too.

Is the Root66 method for T-Mobile? I only see three rooting methods and those are by MrRobinson, Chainfire, and mskip here http://www.xda-developers.com/android/how-to-root-the-samsung-galaxy-s-iii-xda-developer-tv/

Third, alternate if unfamiliar with adb commands and uncomfortable using any command line
Decide if you want to use TWRP or CWM.
If you would like to install ClockworkMod recovery then grab Rom Manager from the Play store and in the menu select to install ClockworkMod Recovery.
If you would like to install TeamWin Recovery Project then grab GooManager from the Play store and select the option to "Install OpenRecovery Script".

Congrats on your phone. I well suggest any of the 4.1.1 root66 because it's jb... I prefer ja baseband because it works better in my area.
And like what the quote said if you want twrp download goo if cwr rim manager. Lol honestly simply going to the recivery website will tell you how to download. So far your research is on point. You can try both recovery and see which you prefer. Twrp may not be pretty but it's sick and far more friendly and with more option
