[Q] Root Clarification

I have rooted a ton of devices from tablets to phones and I don't specifically recall ever needing to flash an entirely different kernel to do so.
My question is, is a new kernel an understood for root access? I was under the impression root was, well...access, to system files and the like.
I'm actually pretty sure devices have been rooted PRE kernel source being released, and that source is more conducive to custom ROMs than anything else.
If someone who knows could clarify, I would be grateful and I also think it may begin to explain why some folks are *LOSING* functionality with root.

The kernel is the heart of the OS. when the kernel is rooted, so is everything else
People are losing functions because the source code from Samsung is jacked up, and the devs are trying to pull it together

Same thing I thought when I first bought my samsung vibrant... They whereusing the international galaxy s kernels untill samsung released sourcs to the current/up to date one... Samsung is know for latd updates and failed source codes
Well thats my opinion but they do make great hardware and tvs lol

Another way to achieve root without replacing the kernel is with an exploit that takes advantage of a bug i.e. in the bluetooth stack to temporarily gain elevated (SU) privileges and use it to install permanent root, flash a new recovery, etc. That's probably the kind of root method that you are more familiar with.

Ahh, that makes sense. See, a few devices I've rooted have been pretty straight forward. But the the OG rooting process on the Nook Color was odd as hell, and then the choice of booting SD or eMMC was another consideration to take. The process of rooting Tablets seems to be somewhat similar to this one floating around for the ET right now.

Will this phone every get a more conventional root?

Coming from HTC/Motorola phones primarily the development for this phone has confused me a bit. Those phones used to get a normal root method pretty soon after release without having to worry about messing around the kernal.
Is there going to be a day where you can just root it and leave the kernal alone or is the kernal/root thing exclusive to Samsung phones?

Whsn i was on att i would use superoneclick. I too was wondering this.

I think he meant the fact that ur using the kernel to get to root instaed the more conventional root method we are used to seeing on devices like htc and so on. It is pretty strange the fact u flash a kernel and then flash to get root its typically gain root then flash somethingy. Or at least thats what my noob ass is used to lol

All the root methods are simple to execute for someone who can read. But I am referring to the fact (as edison said) that you have to flash a new kernal to achieve root. I'm personally waiting for a more typical root method before I root.
Not that I don't appreciate/love the dev community but I like a COMPLETE stock setup with root before I go messing around experimenting because I don't necessarily trust EVERY dev and don't have the technical expertise to fix stuff myself.

Only solution is to just wait, I don't think many would be working on another root method because this one isn't complex, is noob friendly and works 100% I don't see any pressing reason for another method

Yup I hear ya. You can always root then odin bubbys pulled stock kernel for a complete stock root. It's not one click but it's close. Only draw back it there is no recovery.

Conventional root?
What is that?

Umm...there is no other way? There's no exploit anymore guys...it's either flash a rooted kernel or flash a rooted /system. And that's easy as hell
Sent from my SPH-D710 using xda premium

Unless you can get hold of Samsung's signing keys for creating a signed update.zip or find a new exploit (which would have to be fixed eventually because exploits are essentially security holes) you are pretty much stuck with the current methods.

Why should anyone find a exploit to root the phone when the bootloader
Is open and allows you to root much easier....google keeps closing holes in software making it harder and harder to root ...its not a htc where they s-off the phone .....this will probably be the only way to root because there is no reason to find another

What could be easier than putting this in Odin http://forum.xda-developers.com/showthread.php?t=1282415 and hitting the start button

I think the point people are trying to make here is that they wish there was a way to have root and recovery and remain bone stock. So far there is no way to do this. Alot of people don't want to flash a custom kernel at this point because of all the problems people are reporting. Myself included. I am still stock and won't root until devs get this stuff sorted. Maybe koush will figure it out...

To root or not to root?

Im just using the stock gs3 from tmo.
If you all would be so kind as to give me a few pros/cons to root for this phone.
Im am not concerned about voiding warranty.
Im wondering if there are any immediate perks to being rooted:
like bypassing tmo's restriction on wifi hotspot; to my knowledge, tmo now only lets their customers use wifi hotspot with the 5gb plan and not the 2gb plan.
Sent from SCH-T999

I'm short on time right now but if you root your phone you can download an app called wifi tether, which requires root permission, then you use your phone data on your laptop all you want.
With a rooted phone you can also download new roms that people develope and try out a lot of new functions before the official update.
You are more exposed to security risks once you root your phone I believe, but just don't install apps from random sites
Sent from my SGH-T999 using xda app-developers app

I really see no cons to rooting except warranty which isn't really true. If you study the warranty and know your stuff you can verbally defend your right to root and not lose warranty.
Pros: everything.

I do not see the point of having a non rooted android phone with some sort of recovery.. Custom ROMs, themes and titanium backup for all your apps

Sent from my SGH-T999 using XDA Premium HD app

Ive rooted before and I have explored almost all the developers' work on other phones.
Just to clarify im asking about this phone specifically. The first guy already answered my biggest concern about the wifi hotspot.
If you guys can think of any other immediate perks like: unwarranted tmo restrictions that are resolved via rooting this phone.
I will never go back to bone stock gs3 because I would miss out on _________.
Im already aware of the capability to "pirate" most paid apps.
Also there's the possibility of finding a more buttery smooth rom than the stock rom of course.
Extra battery life via underclocking with an aftermarket kernel is obviously another big one, but things im looking for are things on the same level as how rooting allows me to bypass the wifi hotspot limitations that tmo put on the 2gb plan
Sent from SCH-T999

I'd say that if you just want a phone to work and don't get about any extra stuff, don't bother rooting it. If you're interested in modifying your phone and basically being capable of doing A LOT more than you can with stock, root it.
Just make sure you do a lot of research before you do anything. I read hundreds of pages on this forum before I did anything just in case.

Adfree app, which requires root, changes everything for the better.

I mainly use my root for ad block, titanium backup, and maybe delete gsiff_daemon (didn't delete it yet because it hasn't tried to kill my battery yet). Something else that could be useful maybe GMD gesture control

There are a lot of nice apps that require root. Even if you don't have any apps in mind now, at some point you'll probably come across one you want and you'll kick yourself for not having gotten around to rooting yet. Besides tripping the flash counter and warranties the only con is the possibility of failing miserably and bricking your phone, but as long as you follow instructions you'll be fine.

Samsung is locking out root at the kernel level

It appears that Samsung has disabled root at the kernel level on new kernels for the 9500 and 9505. It looks like Samsung is going back on developer community support in favor of enterprise security.
http://forum.xda-developers.com/showthread.php?t=2263788
I hope they don't do that to us in the states - originally I thought it was because of the Exynos exploits but the 9505 is a Snapdragon 600 device.

This is worrisome stuff - it may not affect those of you with a device right now but if it ends up being enacted across the board, you better hope that you never break it.
This is the first time I've seen this implemented on the kernel level. It is by far the most effective way to prevent root as it keeps you from being able to switch to the root user. Without the ability to do that, all software exploits are worthless. And good luck exploiting the kernel itself.

Do they do this with a firmware upgrade? If so, would avoiding any OTA updates and only flashing Modded ROM's be a way to avoid it?

I would assume yes.. and once youre rooted, you dont gotta worry about OTAs anyways....
OP suggested in another thread that this can be an issue if god forbid you need a replacement device..
I then stated that if we saved the backtostock file for the current firmware, this could possibly be avoided by flashing it through odin on a new device, but if samsung doesnt allow that by some means, were screwed

They're barring root at the kernel level on the i9500/i9505, but the difference with those models is that they have unlocked bootloaders and custom recovery with kernel source. It's possible to just install a custom recovery with ODIN and make a modified kernel (both of which are common practice in rooting anyway). They're just making it so that if you want to obtain root, you have to have physical access to the device to flash through ODIN, which is a lot safer in the long run. All this means is that Sally can't be exploited by running an APK or a malicious file to get root without her consent. (It also means that her "techy" boyfriend will have to understand ODIN to get root from now on,)

The T-Mo S4 has an unlocked bootloader. This is much ado about nothing. Read the last few pages of the thread.

i think we are flipping out over nothing. this is probably just for government phones. I think samsung is smart enough to know the heat they will get if they implement this across the board.
Worse comes to worse, carriers start to implement this, and tmobile doesnt seem interested in doing anything of the sort. the verizon and at&t guys are the ones that should be worried then.
but like i said before. making a mountain out of a molehill

It's for security reasons. You will still be able to install a custom kernel and have root. One minute people complain about an exploit the next they complain about not being secure.. it really isnt a big deal. Well I'm not a dev so I can't really say it's not a big deal but it is what it is and you'll still be able to have root.

Come on now. How tech savvy does one have to be to use ODIN. Honestly, my MyTouch 3G was more difficult to root than this thing with ODIN. Point, click, profit. I'm sure all those "techy" boyfriends will be rooting Sammy phones just as easily as they do now. At some point someone will figure out a one click solution anyway.
I agree 100% though, this really is nothing to worry about. I welcome it honestly. Its a great bump for security. Given the current state of things with the NSA and whatever else trying to siphon data like damn vampires and hack everything in sight like Jason. Though I'd say this is more for businesses, we need all we can get. As it sits, we're about as bad off as Windows 95 would be on today's internet surfing warez sites.

Should I update to KK?

I'm currently on 4.3 stock rooted 0x0 flag. I'm curious about KK but heard about a HUGE flaw with apps not able to write to external sd card...Therefore rendering them practically useless.
I'm assuming I shouldn't update ota and instead flash. But what will I need? And has the sd card issue been fixed?

Since you haven't pulled the trigger yet, like me, I would hold off a little longer and wait to see what 4.4.3 brings us. It is just rumored right now but it is supposed to be a bug fix release. From what I have gathered, you really aren't missing anything big by not being on KitKat. I have had the itch to go ahead an upgrade too but I am going to wait to see when 4.4.3 is likely to hit us first.

in my humble opinion....
NO!!!!!!!!​

So if I get any urges to want to change things up I should stay on 4.3?
I'm still debating breaking knox or not. I never plan to use knox and haven't decided if I plan to trade this in for jump or not. I'm loving the battery life and have no gripes but minor hiccups.

I didn't say that.
I was rooted before on 4.43 however, keeping root was not an option when I did the update. I used Odin to flash 4.42 and re-rooted (triggered Knox), loaded the sdcard fix and loaded TWRP in the process.
I was not having any issues on 4.43 though. KK got me better battery usage and access to new software.
If you are rooted, you can apply the sdcard fix. If you are not rooted, I don't think there it's a fix for that.

Since you are still on 4.3, you can easily root using Kingo or de la vega method without triggering knox.
After that, upgrading to 4.4.2 is very easy and you still have root and warranty.
If you don't care about knox, then you can just update and use Chainfire to root 4.4.2 (knox warranty void). It is pretty simple.
I have 4.4.2, root (from my previous rooted 4.3) and warranty intact + SD fix and xposed mods. The phone is just amazing now.

The only issues I've heard due to the kitkat update are terrible battery life and the SD card issue. There's a flashable zip to fix the SD card issue and I believe installing the Foldermount app does some kind of fix. The battery life issue seems to be fixed after a simple factory reset, however, you'd have to root the device like others have stated. My phone runs great on KK. I'm getting awesome battery life and I have not experienced any problems whatsoever.

You can get improved battery life on 4.3 by removing bloat, and there's no need to apply a fix so you can use the sdcard normally. Is there any real improvement in 4.4.2?

After a week of hearing about the problems I just went ahead and upgraded why? Who doesn't like to have the newest? Plus there are fixes if your rooted. If not well maybe you are screwed but who wouldn't want to root? Been doing it since OG evo 4G

Does anyone have any issues recording video with KK? I updated the just the modem (running Slimkat) and can't record videos or sometimes can't play youtube videos in HD. It's not a rom issues. Might go to stock KK and than try reinstalling everything.

Alright I'll have to do some digging and find a flash able rom...and finish my root by breaking knox finally and flashing a recovery.
As easy as it makes things, I'm worried to break knox. Not because of warranty. Lol I know tmo doesn't give 2 ****s about root...
My concern is when I want to sell the device, maybe retaining knox flag will help increase the price point.
This phone is a powerhouse. Easily able to last for the next few years until EoD. Throw In the obvious office features and a still working knox (albeit being able to be reset at samsung warehouses (I'd cite the info but I'm not in front of my desktop)) who wouldn't want this phone for work?
