[Q] Sprint S3 4.3 - Some questions relating to rooting and knox. - Galaxy S III Q&A, Help & Troubleshooting

Hey everyone. Im relatively new to this forum and rooting. I have some background knowledge in programming and other related aspects, unfortunately nothing related to Android. As well as some Linux OS experience. Now as far as i know ROM's could be compared to OS builds. Android 4.1.2, 4.3, 4.4, etc. Rooting makes you a super user/sudo like Linux. I think i have that pretty much correct. Now for the things i know little about.
-KNOX so far it seems its mostly used for enterprises and to see if we have installed a custom ROM. I've seen a lot of different information about Knox. What exactly else does it do/change? As of 4.3 i see we could no longer roll back or we will brick our device. What should i be wary of? I could care less about tripping the knox counter.
-Stock OTA is another thing i was curious about. This simply means an update was installed post factory by user, correct? My girlfriend has an S3 and i cant remember if 4.3 was stock or 4.1.2. I just wanted to clear up if my OTA updated S3 was covered under this.
-i saw one root method which kept the stock recovery but installed the superuser. What is the benefit for having a stock recovery? Would i be able to use a custom one with Knox in place? I was thinking of using a 4.4 cyanogenmod rom.
Sorry if this seems a bit noobish, but my schedule is tight and i spent maybe 6 hours trying to find exact information. Kind of hidden lol.
I apprreciate any answers!

What are roms?

I tired searching for this answer via search bar, but no avail
So I am a recent switcher; been using all iPhones up from the 3G and I made the plunge into buying the Galaxy S III and I %100 love it.
But there is many things I do not understand. First what is flashing the rom and the point of doing so
Roms are custom OS's. since android is an open source platform , devs are able to take the OS and put in their own bells and whistles to make it better. Or to delete the treasure Trove of bloatware put in by manufactures own custom OS's like htc's sense or our own touchwiz

I'm a new user like you! Came from a Blackberry and I'm just starting to realize the amount of things you can do on Android. Quite amazing really.
I'm no expert, but the idea I get is that custom ROMs are custom OS that give you features and options above and beyond what the stock S3 ROM offers. There are many developers working on their own ROMs, you can check out the developer section for that. :3 But before you even flash a custom ROM you'll have to root your phone.

Most ROMs have the option to remove bloatware I think. Even if they do not, once you have rooted your phone and installed Titanium Backup from the Playstore you should be able to remove any unwanted apps.
Omega ROM is a good ROM that keeps the touchwiz interface. It's one of the ROMs that is closest to stock interface. Try googling for that.

If you're a noob don't do anything to your phone, there is a good chance you will brick it.
Just read forums watch some YouTube videos about flashing roms and what not.
Only then once you know the terminology, consequences of a screw up and general feel for things should you attempt to mess with your phone.
There is nothing wrong with stock, if you coming from Iphone first learn your Android inside out.
Don't be one of those asking if they need root, If you don't know what root is or what it does, you don't need it.
Rant over.

Ghost77 said it best!!
If your a noob, don't try to do something to your phone, if you do not know what you are doing!!
With that said, Samsung phones (except Verizon S3) are the easiest phones to root and flash roms!! Do your homework and do major research before you attempt to do anything. Look at youtube videos and carefully pay attention to what they are doing.
Also because you have a S3, make sure you follow and download the right files and roms for your particular phone. For example, use i9300 roms only for international s3, i710 roms for sprint and so on. If you don't know your model number go to settings - about device - model number.
Finally, like ghost77 said, stock is not bad! Rooting and flashing roms is for those people who want that little more customization and performance improvements. For the average user, they probably won't even notice a difference between a rooted phone with a custom factory rom and a unrooted factory device.
Well I already rooted, I installed setcpu what would be a good speed to optimize battery life but keep good performance overall

Everyone thinks that rooting your phone will void your warranty but if you watch this it states that under the "Magnuson Moss Warranty Act" Title 50 Chap 50 Section 2304 C) Waiver of Standards, it basically states that they have to prove that you did something to damage your device to void your warranty. http://www.youtube.com/watch?v=9YcIHaajda8&feature=g-user-u

I have no idea where to start for rooting/flashing roms

My i777 is coming in the mail tomorrow. I'm very excited, its my first Android. I've been researching custom firmware and stuff like that for about a month around the web. I just have no idea where to start. I believe my phone still has some form of 2.3 on it, but it could be the current 4.0.4 ICS.
From what I understand, I update the drivers on my computer with Kies, download Odin to root the device and then what? Or superoneclick? I'm interested in CM10 but I know the bugs are still being worked out. I need my camera, MMS, bluetooth, 3g data, at&t radios, mhl, Touchwiz toggles, all the functionality with no soft keys at the bottom. JB would be great if its possible. Other wise I might as well just update the phone to stock ICS and root it for other stuff I want like sixaxis and over/underclocking apps.
There is a reason we have stickies

There's things like KK 2.3.6, is that custom GB firmware? I know there is lots of information but no where to start.
pretty sure it would make more sense once you actually have the device in hand....seems pointless to create a new thread asking how to get started when you dont even have the device yet.
use it for at least a day or 2 before you start messing with custom ANYTHING
hell, dont even root it right away. just use it as is to get a feel for it, and verify there is nothing wrong with the hardware....if you just jump in and flash custom firmware, how will you ever know if an issue was hardware or firmware related?
Interesting, good point Pirateghost. I was wanting to put custom stuff on there while I had access to a computer this weekend. Might as well wait though. I'll have a laptop to mess with everything at my own pace by Black Friday anyway.
If it is still running GB, should I upgrade it to ICS, or would that hinder the root process when I want to do that?

The second part of your reply is absolutely spot on.
The first part i dont agree with a 100%.
I too plan to purchase the i777 model in the not too distant future, and its always a good thing to start reading early. Just like getting a feel of the stock rom/hardware is essential.. its always a good thing to read up well in advance. By the time a person is analyzing the h/w.. he is in a position to relate with other user's experiences.
I too was reading up all the stickies and really did got stuck up with the KK6 2.3.6 thing mentioned right at the start and no clue/legend being mentioned as to what it was. I googled a lot and many results had the same thing.. simply started using the terms w.o any hints.
It does gets confusing tbh you know
The thing is, I understand and know the stock hardware and firmware very well already. I have been using my girlfriend's GS2 from Sprint, the "Epic 4g Touch" since she got it in May. I've used it with GB and then ICS in August (I had to tell her to stop ignoring the notification, the update was a good thing!), but it will be good to evaluate the item to fully determine that everything is good with it.
It seems like in your first post, you steered yourself away from CM10, but everything you listed works except mhl I believe. And if you really want that, you will be able to dualboot into shostock once Siyah kernel gets updated.

(at&t SGH-I777, sprint SPH-D710, tmobile SGH-T989, etc)
So CM10 is good for everything except mhl...what about stock ics from kies and rooting it after that. Is that simple to do?
I'm interested in project butter and all but even ics would be great as long as its not a CPU hog and laggy. I know it runs fine on the epic 4g touch.

Also, breaking Wi-Fi is nothing. Flash a kernel to obtain cwm and you've got Wi-Fi back and you're ready to flash a ROM.

MDK, ME7, SGS4 And a lot of disappointment...

Hello everybody! I just got my SGS4 a couple of days ago... I handed my SGS3 down to my wife (running beans 18 what a monster!) and headed for the forum to see how to root and unlock this puppy... When I saw that Beans was rolling out his rom for s4 I knew I did the right thing... If i only knew... While I was tinkering with my phone a new update notification came up and without thinking I just accepted it (being used to accepting updates on my nexus 7 unrooted and never worrying about otas for my phone) as it turns out I had an MDK phone, now no more... and the more I read on the forums the more I wanna kick myself in the face for being so naive... Especially because I used to be a moto owner!
Well after my sad story I got a couple of questions... I rooted my me7 what app do I freeze to avoid otas?
And another trickier question can any knowledgeable user explain (dumbing it down a little) why some phone's boot loader cannot be unlocked ever? Just out of curiosity...
Thanks!

Never really did pay much attention to this me7 but I never took the update, does this mean my bootloader is unlocked???
As for having a locked bootloader its probably just a matter of time before someone finds a way to unlock it.. Let's hope

There's a lot of talk about this ME7 disappointment. So much so, that it has it's own thread for all things related to it.
That being said; freeze SDM.apk, FWupdate.apk, and I think someone mentioned Keychain.apk.

Your bootloader is still locked, but there is an exploit that allows you to install ROM's and Kernels just like if it was unlocked, as long as you are on the mdk build.
Have it Jtagged back to MDK or wait for safestrap. I used safestrap on the bionic, it's an excellent app that will allow ME7 peeps to run custom roms.
Don't worry, you have options.

Jtagging involved taking the phone apart and jumpering two points on your board. This has been used on HTC to achieve s-off on some devices. It's very risky as you have to solder them. I have not heard of anyone doing it on the s4. Or any Sammy device.

I am in your same boat man... Got my phone a week ago and just carelessly did the update and found out later that day I shouldn't of... Oh well, liv and learn I guess.
There is a guy on here who said he can Jtagg the S4 ME7 back to MDK, but at the moment he is only doing it for devs in order for them to keep working towards unlocking the boot loader.

Got my S4. What now?

Hey guys, just got my S4 and I'm really happy with it, but I'm just so lost with all of the locked boot loader things and Loki ect. I don't know where to start at all. I'm sorry if this is the wrong thread to ask, if it is, could you guys point me in the right direction? Once again, sorry.

Best place to start is finding out what build you're on as options are limited to some degree depending upon that. I'm assuming you're going to be on one of the newer ones. Lemme know and we'll go from there bud.

Unfortunately, I am on the newest build that came out. I had no idea that the bootloaders were locked until after I updated. I actually came from the S3 so I pretty much know the tools that I need and things like that but I have never ever heard of Loki before, all I know is its some type of makeshift work around for the bootloader.

You will not be able to install a custom recovery on your device, as any build past MDK (the original build) has pretty much been locked down. Only MDK people have the ability to use Loki.
Your only alternative is Safestrap, basically you can only flash ROMs that use the stock kernel...which means no AOSP. There's a thread for it here somewhere.
Sent from my SCH-I545 using Tapatalk
Damn that's dissapointing to say the least. I really loved AOSP on my S3 and I really hear that its pretty great on on the S4. Oh well, I will just enjoy 4.3 until 4.4 comes later this month, or year due to Verizon's AMAZING speed when it comes to updates. -_-

if you do some reading, you find that safestrap recovery is available for your phone....limited ROMs but at least its an avenue.
read and research !!!

Wanting to get rid of 4.3

It looks like a lot of people don't care for the 4.3 "upgrade" on their S3s. I've had nothing but problems since the stupid "upgrade." I just did a reset and found out I can't download some apps that I used now. 4.1.2 was fine with me. I wouldn't mind going back to that if there is a way to do it without all the bloatware apps that I don't use. I would like something that is lighter and more visually appealing though. Any suggestions on what to use? What's the best guide for rooting and changing the software? My provider is Verizon.
Wrong phone and wrong forum, this is for the i9300 and questions go in the q&a forum.
Try reading the sticky threads for guides, but don't flash anything from this forum as it will hard brick your phone.
