[Q] Thinking about Rooting - T-Mobile Samsung Galaxy S II SGH-T989

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.

But if you did OTA 2.3.6 you should have it ....

Cool, thanks!

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

First time flashing in this new age

Hey all, long time lurk, first actual post here though. I used to jump rom to rom back when I had the original Droid on VZW, but that was so long ago, at least in terms of Android Development anyhow. So ffwd to today, I've had my E4GT now for perhaps 2 months, and I've already rooted it, flashed a Team Rouge Recovery to it (cause it was the latest I think), and am on a stock GB EL29 Rom, and I think an EL26 Kernel.
Now, I know that things have complicated so much more since the last time I was savy doing all this, so I'm vague and still learning about all the different things that can be switched in and out, here and there. But I've been too caught up with all of the recent ICS issues that were presented with the leaks and the actual release. I've since found a rom that I'm comfortable with, AOKP 7-13 , but I'm not trying to mess anything up despite having done nothing but read for the past month and a half about what to do and not to do. One thing I am absolutely sure about is that I came into this scene at a horrible time lol, things have been changing as I read them!!
Now! With this rom, is it completely nessasary to use this specific recovery, CWM5? And, is this the recovery in question? If not, please point me in the correct direction.
And "the normal route" that is mentioned in the first information post in that AOKP thread, would that be the flashing of an ICS rom from a GB rom to prevent the emmc problem that was happening, even though such this rom has that feature removed (at least if I read it correctly)
I'm not stupid nor am I completely horrible at following directions, but after feeling like getting the run around just by attempting to piece together information from different sources, it would really just put my mind at ease, and stop the headaches lol, if someone whom this wasn't so...new to could provide me an outline to follow, or at least do this, don't do that pointers.
I know this is long, and thanks for reading. I'm just hoping to get back into the scene, I hate being anxious and not know, <-- ie. my current state

Okay, first of all, AOKP already comes with a recovery (TWRP). However, if you would rather use clockworkmod then you can use this: http://tinyurl.com/7ysnylg Also, in any case where you want to flash a different ICS ROM, I suggest you use el26 CWM.
I'm aware of the TWRP that is included with the AOKP rom (listen to me, slinging around slang like a pro, lol) I only felt I needed to use CWM5 because it specified it in the instal instructions for the rom.
I would assume that I would need the CWM just for switching ICS's in the future, if that does turn out to be what I'll be doing, seeing as how ICS looks like it'll be nothing but improvements from here on oot.

Ooooh I get you! yes its best and suggested to flash any new ics rom from el29 stockrooted
Odin el29 stock rooted
Then flash el26 cwm kernel
Reboot to recovery then flash the ics rom
If your already on an ics rom MY method is to always Odin el29 stockrooted

Righteo, that helps some. Now I just gotta back everything up. I made my original backup once I first rooted, I shouldn't need to make additional, right? You can find rooted, stock GB roms to go back to...right? Lol its late...I need another doobie :cyclops:
EDIT:
Actually, I'm already halfway through that. I am at el29, stock rooted. And I have the el26 kernel. I just need the CWM recovery, then the actual piece de resistance, the rom. Right Krazy?

I was actually in a similar situation as you. I came from flashing on the HTC Hero(which is running AOKP at the moment, and I'm soon going to flash the new Jellybean rom that was just released for it), and that phone is completely different from the E4GT. Although i didn't start flashing from GB, I started on ICS.
I actually went from FF18 Stock Rooted to AOKP milestone 6 Friday the 13th using Agat's recovery from source, and it's a safe recovery, without problems. I am now loving AOKP

The yellow triangle is Samsung way of telling the techs an unofficial kernel was flashed to the phone. People use a jig or if your on ICS you can use triangle away to reset the binary counter.

Thanks. I am looking to flash for the first time on this phone also, just got it a week ago. I came from the Vibrant which was so much more simple. Another question if you don't mind. I am on the now running stock OTA ICS. Do I just need to Odin a safe kernel then flash which ever ROM I choose or are the ICS kernels that are built from source now safe to flash from?
The kernels built from the source are safe. Agats kernel with recovery. You can flash that kernel being on stock FF18 and flash from there.
Edit: the agats kernel I have is for TW roms. So just do some research on what kernels you can use. (Cm9 and AOKP use different kernels.)

I have done a ton reading, just stuck in the old ways of my old phone and simplicity of flashing on it. It was all a little confusing because even some of the updated ROM threads still say flash back to EL26 first, which is also a TW kernel isn't it? But then I read in another place it is safe to use Agats kernel built from source and so on. I was a little shocked at considerably less custom ROM options on this phone compared to the Vibrant. Granted the Vibrant has been around longer, but there were so many more options at the start which kind of leads me to think it is just that much more work to do that on this phone. By no means is this a negative remark toward any developer, just sort of expected a lot more because it is a nice phone. I was looking to flash the Platinum version of this rom http://forum.xda-developers.com/showthread.php?t=1712362 since I love the color red. But, thanks for help. I really appreciate it when someone actually gives an answer to a question instead of bash people new to a phone.

And if I remember right, doesn't it only trigger if you flash an unofficial kernel through desktop Odin only? I know the Auto Root Package won't trigger it, and neither will Mobile Odin.

Your correct only desktop triggers the yellow triangle.
Also just my steps to flashing roms 4 the e4gt
1. odin stock el29 rooted
2. flash the el26 cwm kernel (I provided on a few post back)
3. boot into recovery!
Flash what ever you want!
If you want to flash something else repeat those step! As you venture on you will get the hang of things! I hope!

I had all these on the Vibrant, but non are as stable as they were on the vibrant (as least by what I have read). AOKP would probably be my first choice because I am very familiar with Romanbb's work since he had a Vibrant at one time and is one of the best dev's.

Paranoid is a great ROM but some things are just a little to small for my tastes. But if I had a Galaxy Note then Paranoid would be the one for sure. But still my question wasn't answered, not getting smart, just looking for an answer...Do I need to flash back to EL26 or 29 before flashing an ICS ROM, or can I use the new safe kernels built from source? I think I need to be held by the hand on my first one.

You should be good from one of the safe kernels from source. I used Agat's recovery from source to flash AOKP from stock FF18 with no problems, did the normal factory reset instead of one of those format all zips. Not a problem with it. It should be safe to do as many factory resets/data wipes as you want from what I understand.

The agats kernel is safe. Flashed two ICS roms already. If you like red, check out the hooligan rom by MaNuFaN721. Themed red.

Foolproof overclock for rooted uvalh2

Okay, I'm pretty noob at this. I just got my phone monday, rooted last night..tried to load up custom kernel (perseus) and encountered black screen problems. Finally after unbricking my phone and rerooting via Odin after 3 hours, I am finally back on a clean slate.
Anyone have a foolproof method via Odin to gain OC for latest stock OTA (uvalh2)?
Any simplified help would be awesome!

You can't overclock the stock kernel, and i don't recommend flashing a custom kernel over lh2, none are perfectly compatible, they break Wi-Fi among a couple other things.

So is there not a method I can utilize with my build? Sorry for my noobishness, but i havent attempted to mod a phone since the G2 was initially released. Back then, I was able to utilize scripts to OC + visionary r13. Is there anything similar to this?
No there is not.
There is one LH2 kernel that I am running right now that is overclockable. It is Trinity Kernel in the Original Dev section. Make sure you pick the correct one and please, please, please make a nandroid before you flash anything. If you have already soft-bricked your device, spent hours restoring and are now wanting to flash a custom kernel, you need to make sure you are covered (ie nandroid and reading).
Please note that the Trinity kernel for LH2 is experimental and should be treated as such. Meaning that the LH2 source code has not been released, therefore the source for this kernel is most likely the Sprint or VZW or Int'l version. I am not a kernel cook, but I do know what I am doing.
Tread lightly my friend and good luck. You've already had a rough few days with this shiny, new, extremely expensive toy.

Awesome, thank you for your input. I suppose there's alot I still need to learn- however with a full work load and a lovely girlfriend, it's hard to find time to do extensive research. Meh, I suppose I thought it would be alot easier to OC.
I think I'll just try out the new jellybean ota leak L17 for now.
...and yes, you're right- I should be more careful because this was indeed an expensive toy. I nearly freaked out when I soft bricked my phone!
aside from kernel, MSM8960 is only rated to 1.7GHz..
Mine already runs hot and from the stock build logs, tsens_tz_sensor0 or 4 (CPU temp)
is used to throttle the CPU:
57 -> 1.134GHz
60 -> 0.918GHz
64 -> 0.702GHz
105 -> shutdown (or 90)
You'd need a metal battery cover heatsink lol
I've been using the newest Trinity Kernel for UVALH2. It runs flawlessly. Even at 1.72Ghz running multiple applications I'm not seeing anything above the 115* area.
Stable, Smooth, Speedy, Cool.
Good Kernel for Rooted, Stock Rom, T-Mobile GS3's running the recent official OTA update UVALH2.

I've been using free gs3 and xquizit v70 with ktoonsez kernel, I've tried to go up to 2.1ghz, but went back down to just 1350mhz max clock and 96 mhz min.clock, and its still smooth and fast, i even did undervolt. Why Don't you try those rom and kernel?

Awesome..in going to find that a try after doing some research. Is it necessary for that rom to be used for that kernel? Excuse my noobishness
As for perseus being intended for non-tmo, the guide claimed to be compatible. I think my mistake was initially flashing an old kernel intended for for preupdate. I dont know.. lol
I usually just go to the t-mobile galaxy s3 forums, just to make sure that everything i download and install are all compatible. Lol. Don't want to brick my s3. You'll find everything you need there, from stock roms to custom ones, kernels, even themes and lots of mods. Just be patient searching and reading. Once you get the hang of it I'm sure you'll try every rom, kernel, etc.
I came from an Htc hd2 now that's with my 8 yr old daughter. Lol. I learned a lot from there, once i got my s3 it was a piece of cake to root and customize it to my liking.

[Q] Best rom and best kernel for T999V

Hi all! I want to know what is the best Rom and the best kernel for the SGH-T999V. My carrier is Videotron.
Thanks

Define best. Are you looking for best performance, longest battery time, coolest custom features, etc?
Battery life and coolest feature
Sent from my SGH-T999V using xda app-developers app
^ I have same question. Whats kenrel comparati with T999?
AOKP tends to have the most custom features out there and is pretty stable from what I've read. CM10 has the biggest community and the most support so it'll be the first to get a fully stable release.
And for battery life, I'd suggest Lean Kernel and don't overclock anything.
How can I install Leankernel without bricking my phone?
Sent from my SGH-T999V using xda app-developers app
Put the .zip file on your SD card then use ROM Manager to boot into CWMR. Wipe cache and then wipe Dalvik cache. Flash from there. I would assume since Videotron is combined with the T-Mobile forum all the ROMs and kernels for T-Mobile would also work for your phone. The only difference that I can tell from T-999 and T-999V is the 999V is Canadian. Other than that just don't flash any T-Mobile specific modems or radios and you should be good.
Ok so the kernel and the radio are not tbe same things. Im sorry I am totally noob in this.
Sent from my SGH-T999V using xda app-developers app
Don't sweat it. We've all been there before. There should be a sticky in one of these sub-forums with a TON of information about what everything is.
And yes, the kernel and radio are not the same. Think of the kernel as the engine powering everything and the radio as what interprets the signal you get from your provider. It's a bit simplified, but it's an accurate description. As long as you avoid flashing T-Mobile modems and radios you should be in the clear. To be honest, I've messed with radios before and it's really not worth the hassle 9 times out of 10 so you're really not missing out being with Videotron.
I have no doubt that stock kernel is and always will be the best kernel possible for this phone. Sammy has done a great job! Kernel devs will do their job(fix and break what they fixed before then break it again so you become a flash addict) but stock kernel will remain the best choice at the end.

SmartassV2/SIO. Not to mention overclocking and other optimizations.
Your argument is invalid.
And flash some roms and kernel just to try can break the phone? Will the performance will stay the samdme?
And thank you for all your answer.

Sorry if it's it's off topic . I want to flash my kernel with Trinity
I'm wondering which is compatible, due to many many files for different roms and etc, for my phone which is Samsung Galaxy S3 SGH-T999, rooted and stock everything. I'm also a noob , too. Brick my phone once and i don't want it to get replaced . LOL .
And I also want to install the AwsomeBeats v3 mod . Is this mod compatible for all Android phone ?
Any suggestions or help will be much appreciated .

It's possible, but not likely. If it was that easy to break the phone there wouldn't be such things as nightlies (ROMs that are updated pretty much every week night). I've had a few instances where I flashed the proper kernel, but it wasn't compatible with my phone. It's a simple enough fix, but nothing close to soft or hard bricking my phone just by flashing. Just make sure you don't do anything stupid like removing the battery mid flash, run out of battery mid flash, flash a ROM for a different carrier, flash a kernel for the wrong carrier (although kernels aren't TOO picky).

To be honest I was interested in trying Trinity myself, but gave up on that. I couldn't figure out what the hell was what and which was the most recent due to the naming of the different versions. Unless there's something you REALLY want that only Trinity offers my only recommendation is to move on. Or find someone here who has a signature saying they use Trinity and ask them which version you want.

I'm glad you are happy with the stock kernel. However, not every kernel works the same for everyone. Therefore, stock is not the right choice for everyone.

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)

Seems a bit too plain for my taste.
So I always thought our devices had wireless charging capabilities but I see that you need a certain special back cover, etc. guess I am going to do that mod I found online lol

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/
edit: ok so I looked i think it's the MrRobinson one, but how do I know which T-Mobile image to grab from the selected?

also after that would you suggest doing
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
