Hi,
I just got home my Samsung Galaxy II, and i am thinking about rooting it.I want to know if it gets better or more worse( for example the battery)
But can anybody tell me the positive things and the negative affects of rooting the phone?
\You only root for access to administration rights on OS . You dont root if you do not use apps that dont need root .
Root has nothing to do with battery at all .
Root or custom roms void warranty

Here. But if you put back the stock ROM and kernel before servicing and use a USB Jig to reset the ROM counter I don't think they will understand that it was rooted, so in that case it shouldn't void your warranty.
Regards.
Before you root... have a reason to do it. Don't just root so you can say you've done it. You're better off leaving things in a warranty state as long as you can.
There is no negative to root, only positive. Root gives you added functionality and features with zero downsides.
but if i dont root, can i still download good free apps? or is it only bad apps if i dont root?

There are tons of great apps. Just browse the Android Market. A small portion of those require rooting.

This is not neccessarily true. Danish consumer law, which is derived from a European Union directive imposes a mandatory 24 month warranty period. Naturally it does not cover third party software such as Lite'ning or Villain, but unless rooting or flashing is the cause of the failure, the warranty still applies. Since software cannot physically break, the primary use of a warranty is in the event of hardware failure, where the warranty still applies - despite flashing/rooting.

Yes, that's true, if you wanted to be 100% clear and honest about issues and what causes them. Your provider, however, will disagree. They will say "You've installed custom firmware on your device. That means we aren't responsible for any problems." which I totally understand, despite the fact that a problem is usually nothing to do with this!
Only root if you can live with the consequence of bricking your phone. If that won't be the end of the world for you, then root because you learn so much about Android doing so and you can have so much more fun with your phone. But if you can't, stay away because you will have occasions when things go wrong and you will wish you had left your perfectly fine phone alone.

I understand that flashing could give a shady retailer an opportunity to BS it's way out of it's liabilities, if the customer is not familiar with law and processes.
Because if a retailer denied me a repair, I know the exact buttons to push to bring sense into his head.
I don't know about the UK, but in Denmark we have an authority called the Consumer Appeals Committee that adresses complaints from consumers. It requires a £20 deposit to file a complaint, a fee that will be refunded unless you lose the complaint. If you win, the retailer must follow the verdict and additionally pay a £1600 processing fee. The mere risk of of losing a case at the appeals committee and paying the processing fee is usually enough to bring the retailer on track.
Ok, so if i dont root, it is better if i get a problem with the phone and wants to change it or something.I dont think im gonna root because i can get some good free apps.

When you need an app that needs root then root .
If you can unroot return to stock and clear the rom counter then you should have something like a 99% chance of passing any inspection .
Its not the seller or repair man that voids warranty Samsung decide what they will repair or pay for repairing . Letters sent out clearly state they will not reimburse repairs for work on phones with custom roms or rooted .Repair centre guy though has the choice if he so wants to ignore custom rom and just flash a stock rom without saying a word to Samsung .

Personally, if you're perfectly ok with your phone the way it is, don't root it. It looks to me like you don't need the things rooting provides and you haven't needed an app that requires root access.
Also, rooting can brick your phone if you don't know what you're doing. I suggest getting familiar with your phone before venturing into root. Although its an exciting world once you step through that door.

Does rooting the phone (which I understand gives me administrator rights) give access to more settings options? Other than being able to install some more apps, are there any other benefits? I'd really appreciate some examples..

Rooting really has nothing to do with being able to use different apps, or free apps. Rooting is all about getting more function out of your phone, more settings from a good ROM, new features like enabled FM radio and things like that. Apps aren't really relevant. You can go get pirated apps from anywhere and don't need root for that.
Root is about gaining admin rights to your hardware to do anything and hack it to death.
I see. I am running a standard ROM, I'm on O2 in the UK. What extra features will rooting unlock?

I think it's high time that I present myself. I'm not as noob as I can be in the forums. Yes, I don't know Android, since electronics isn't my field of working anymore. I have studied electronics and went for a master in Engineering Physics so I'm not a newbie when it comes to hardware.
Just that I got this (stupid?) 30-year crisis and went for an MD instead.
My foremost field of working has been Unix, but I'm schooled in lower levels and had done both VHDL/Erlang projects and have been really fluent in asm. But that was a LONG time ago when Motorola 68xxx was the ruler (oh, the ****ing best cpu ever made code-wise).
The aversion and stop for asm-coding came with Inter and that was around the 486-time when you had to fiddle with the memory and stuff.
I have kept parts on my knowledge. Did a SOC for a big company with a linux that I pressed in on 128 kb of Rom but I'm not up to date with arm-asm and I can say that the last time I ever coded something was around 1996 since I started with design/capacity planning of hardware and management.
So the time has flown by. I'm a C-coder. Never coded a line of Java in my line. I'm also from Sweden and I don't know where you are from but if you are from USA we have quite some different rules here, especially when it comes to consumer law that can be used for us.
Ok. Enough **** about me.
I called Samsung today and this is a summary of the conversation I had.
I asked them about why the consumers had to use the Knox and how to pass it as a developer.
He could not answer it.
I asked if I trip the flag, why does it forbid me to sideload my own developed applications?
He could not answer it.
I asked how to remove it since as a consumer I had no use for it and this is something that I have not signed up for.
He said that I could send in my phone and have it reflashed to a lower version of the firmware.
I asked for specifications about it and said that knew it's a SE-linux containter (because it is).
That he could confirm.
I asked him what for specifications for the boot loader since it hinders me in my work.
He said that the only thing he could provide was a downgraded one (see above)
I said that I don't want a downgraded one since all use 4.3 and that is the future.
He could not provide that.
I said that maybe this is a deal that Samsung has done with NSA to provide them with information since I don't know what the phone sends out since I'm locked out of the kernel.
He said that he understood that he would feel the same sentiment.
I asked him if consider us who are developing on a low lever as valuable people the brings the phone forward.
He agreed.
I told him that I don't consider tripping the Know-flag to invalidate my warranty since it could be tripped in Kies (as reported here).
He agreed on that and told me that I could then contact the service for a reflash.
I told him that the option left then would be to crack the boot-loader as with the rooting.
He said yes.
Note that this is in Sweden. But the info in any case is interesting since he very well knew about this.
So the info I got. Yes. It's a Se-linux container and it is reflashable. Since it's reflashable we now know that it's not an e-Fuse and can leave that question. Since it's software it's crackable.
Seems high time for me to start to update myself on arm-asm. I got lazy with VHDL/Erlang
Also, this has not been the field of my quite messy life. Going from electronics to computers and Unix towards medicine.
I don't have a J-TAG. What do you guys use? What have you found so far?
Do we have access to the very beginning of the boot strapping?
With that I mean the first asm-lines that the phone do as a start. Is that hardware or is that software?
In this case. Could someone please provide me with that. As I said. I don't know Arm-asm yet, but I'll try to freshen myself. Asm is asm and the last thing I did with Arm was working with a Xlinix that had 2 cores in the die and then a VHDL-part. Really nifty. But that was 10 years ago.
My other problem is time, like you all, since I'm guessing you work full time.
But can someone update me or give me links to white-papers etc on how the phone starts? I guess there is quite little about it. It's not the glorious days where you could get papers on the clock-penalties and how revolutionary it was when you could do an instruction on both the edges of the clock-wave.
Sorry. I type a lot, but I really hate this and yes, people can say what they want. When Ericsson still made phones I had a special firmware that showed a LOT more then what a normal user would get and how chatty the phones are without us knowing. So the option of spreading the "Samsung has made a deal with NSA" WILL scare people whatever you think. I have done "activist" things before and you just have to present it as a theory and get to the point where the rumor will get viral.
I was truly amazed when my complaint against RIIA went viral and the "Govermental institution for internet privacy" got over 5000 complaints in one day. Don't know how that works in other countries but every document that you send here is official and need to be filed. We also have the reverse policy that seems to be a bit unique. Everything is open until it's classified as not public. Not otherwise as it seems in most countries.
Ok, off topic. You have to live with that if you want my help that I'm offering here.
Where are you know in the dissaembly of the boot-loader? SE-linux CAN be cracked but if t's scrabled with hardware it makes it a bit harder.
Ok, enough from me. Want me to start to dig with the Cortex-chip? I know that Qualcom are more then happy to provide white-papers on their chip. Just a matter of cost.

Btw, got a i9506 today. Will be interesting. Also got An Note 3 and that has 4.3. Both are "pre-knoxed". Need a good burn-in software before i start to root them. Know any?
I have not noticed this behavior before but although they are connected to a Wifi they still search every 15 s or so for others. I don't recall if my old one did that? My HTC doesn't.
But anyone now how the phone boots-strap? It's too late after having a kernel.
Since it makes it before it loads it, it's not a real SE-kernel because then the custom ones would work without even touching Know, would they. And they trip the flag.
So the check must be done earlier? Besides, are the kernel sources enforcing MAC? I have not set up a build env yet so that's all the questions.
And any good J-Tag that you recommend?
Double post. Don't know how to remove...
You might send it in, if yours is qfused like the ATT model they will have to resign the MDL bootloader with a certificate that has not been invalidated by the qfuse.
If they do that, you can extract it and we will atleast be able to flash back the i9505.

Do you still think it's actually an e-fuse? If they can "reflash" it as I got the info yesterday that means that the e-fuse is in the prom because how else could they just change it?
I'm still not sure about the fuse thing? Do we have that black on white that it's the case?
Because I think that they have just a small SE-Linux in the bootloader and then they can enforce all the rules they want. Your phone will behave
basically like a jailed Unix-account and the only success in cracking it is to prevent it to load. There is no other way.
I just sent a long and nice mail to Samsung. Will see if they contact me tomorrow.
I basically asked them why it's enforced on us private citizens and if we should start to openly question the motives on Samsung in different
mobile user forums. Because I will. Would be happy if someone would follow suit and help out.
Bad publicity is something that is hard to get rid off. Also, we never got an opt-in/out.
And if they start to get it it WILL scare them. I've done that before but not on this scale.
If need be I will drag them through our Consumer department. They are not so fun if they bite on the case and it just cost me time to write a letter of complaint to them.
"Freedom loving" Sweden will not accept spy-ware on their phones. That is one of the strong thing here. Consumer power and the equivalent for governmental issues.
Well, I'll report tomorrow. Btw, I got my new phone yesterday and it was a I9506.
They don't sell the I9505 anymore and the prel result with plain kernel is that it's about the same speed as Note 3.

I believe this is specifically for the i9506 as the qualcomm chip in yours is a different prefix (though they are very similar in construction to my novice eye, the boot process is still a bit magical to me though so grain of salt all that.)

Hi everyone!
I just want to share with you guys that I rooted my SGS i9505 with CF root and knox flag was tripped to 0x1.
I flashed the custom rom and i got bootloops and i tired of fixing that issiu. I went to Samsung service center in Dubai and they reflashed the MJ5 stock firmware.
Later when I checked in Download mode Knox flag it was 0x0. I guess I am lucky because I have my warranty back. Sorry for my bad English.

That is interesting that they reflashed the stock firmware without negating your warrenty coverage for the tripped knox flag.
The question is were they supposed to do that or did they just screw up?

And about the reflash. They have offered that to me too if I "happen" to trip the Knox. So e-fuse, no e-fuse. Duck. I don't know what to think anymore.
As someone who's mother accepted the update to MI1 a few days ago, would contacting Samsung be a way to possibly downgrade the baseband?

just a few quesitons to you sir.
did you wait for some minutes or did it take some hour?
was it repaired or motherboard simply replaced?
if they reflash the firmware it looks to me they have a "restoreable" that will be reversible if you flash it, just to ask why didn't you ask him what he did
Hi,
Here's a unique idea.
Let's pass the word to boycott Samsung over the whole KNOX fiasco.
Use social media, ie. twitter, facebook, etc. to pass the word.
Tell everyone you know not to buy a Samsung phone this holiday season.
The only thing that will make companies take notice is if we take action.
1. Just the attempt to downgrade firmware or load unauthorized firmware triggers KNOX in 4.3 and voids your warranty.
2. Now that's not bad enough, because even if you now load a signed piece of firmware KNOX still stays triggered.
3. If my warranty is now void, I should be able to do what I want, but nooooo, my bootloader is still locked and I have no warranty.
So Samsung should fix this. Just trying to do something should not void my warranty, especially since they block the possibility of being able to change the bootloader.
This is not Samsung's device.
Everyone does not need nor want KNOX and those that need it, know it.
The majority of devices are not enterprise, so why are they forcing an enterprise and NSA solution down our throats!
BOYCOTT SAMSUNG!!!

I really doubt something like this would work. The only people on board would be those of us who mod, which make up such a small portion of Samsung's sales, they wouldn't care. The general consumer is where they get their money and said general consumer couldn't care less about Knox.

Samsung sold 213 million phones in 2012.
Two things...
1) Though XDA and all seems huge, only a really really small percentage of cell phone users play around with crap that will effect knox. I doubt a large number of those "don't care" people are going to want join your campaign.
2) There are a lot of great things about Samsung phones and products. It's like people complaining about VZW cost and billing and marketing, but they have great coverage and I'd never switch because someone starts a "boycot Verizon for $$ reasons".

They can make lock downs most of this is to stop forms of piracy in my opinion. I'm new to rooting but I'm from the modding scene. I have no worries do to developers here as I do on game system modding. Give them time nintendo,Sony and Microsoft have done similiar things with updates the push regularly to their gaming consoles and boycoting will not work do to the modding group is a small group that has a small impact they already planned on loosing.

Knox is high security put on the phone as a bid to gain military contracts. They only want the most secure phones. Do you think Samsung will stop trying to get that military high $$$ over a few people saying they won't buy anymore? Also add to this many corporate businesses that buy bulk phones and contracts and want a more secure phone for their Exchange and corporate software. XDA users are barely a ripple in that ocean of waves.

Umm...yeah...because the international versions are not locked...neither is Sprint...it is a carrier request to lock bootloaders on Samsung phones, otherwise all phones would be locked. Locked bootloaders and Knox are not the same thing. This thread states it is about Knox. True that Knox in the bootloader prevents you from downgrading the firmware...but does not equal locked. There are many phones with locked bootloaders but no Knox.

It's not just about a locked bootloader.
If that was all, no issues.
KNOX and SE Linux are now baked in from the bootloader up.
No it was not on my phone when I first got my phone and was not detailed before they rolled it out.
Messing with the bootloader in anyway even an attempted downgrade, void your warranty.
Not tampering by using unauthorized software, but just trying to go to an older version of *SIGNED* firmware will void your warranty.
My issue is this, if my warranty is now void, why can't I install any *SIGNED* firmware that came on the phone?
The article, found here, has quotes from Chainfire, and says it is possible to downgrade the phone's firmware, but the KNOX bootloader will be tripped. It then states that after the downgrade, the bootloader, being tripped, will no longer accept any KNOX-equipped firmwares, meaning once you go to 4.2 MDK, for example, you will no longer be able to go to 4.3 MJ7. However, your bootloader will be downgraded and will accept Loki/custom recovery.
Warranty only lasts a year from purchase date, and mine is up, so Im fine with fiddling around to get my bootloader back. Can someone confirm? I have messaged Chainfire on Twitter and am awaiting response from him.
As this may not be true, I have not yet tested this myself. If Chainfire confirms his quotes, I will attempt to downgrade, and if it works, everyone can do so as well, just by giving up warranty. That may be a high price, but for some, it may be worth it.

I thought that it was still the carriers decision and that's why us on Verizon are still screwed.
My Sprint S4 has Knox and the security isn't the same, that phone is currently running Philz Recovery with Carbon on it. Clearly there is a Knox Warranty Void bit now on that phone but I don't care.
Hey I'm with you though all the way... Just that's how I took it.
I realize you're talking about the actual bootloader...

I contacted Verizon about the possibility to do an individual person's request to unlock a bootloader for aid in development. They said it was possible but not to do it because it voids warranty. They then said theres steps to follow on Samsung's website. I checked, couldnt find anything. The Dev Edition S4's bootloader is not unlocked, just unlockable. You need to get some sort of token to push to the phone over ADB to unlock it. I could not even find those steps on Samsung's site.
Samsung said my phone itself, the SCH-i545, could be unlocked and downgraded, but would not do it for me and again tried to discourage me from it because it voids warranty. I told them I am a developer, and the phone support tech told me to use the "Voice of the Customer" email link that goes directly to the executives, and they might make an exception for me, since I am an aspiring developer.
I googled and googled and googled, and eventually found that link, that shows it is possible, but it will void warranty. Theres a way to simply flash stock MDK, and it will just work, but the phone will show the warranty void flag. I dont give a damn about warranty. The bootloader was forcefully locked from me, as an update magically installed itself while my phone charged. I was downloading a ROM to flash with Loki overnight, and when I woke up, my phone was on ME7.

Well that's certainly interesting. And I'd be willing to fire off an email to the executives if that's all it takes. Something makes me feel like they're not going to make any of that easy. I don't care about my warranty either so... Let me know how you make out!!

No, it doesn't say that you can downgrade.
What it says is that attempts to downgrade will set the "Knox Warranty Void" flag. We already know that.
Unfortunately, I wasted my time reading the referenced article, which had no new information content.

I deeply apologize....I didnt really expect for a top developer to read this article. I just figured others could look into this and maybe get something from it, I never expected anyone to actually follow what it said.
Again, my apologies! :crying:

You wouldn't expect a developer working on a downgrade to read this post? Lol. If it were as simple as downgrading and taking a loss on the warranty there wouldn't be a couple thousand dollar bounty on a workaround. Most people on here would gladly tell Samsung to shove their warranty where the sun doesn't shine, myself included.
Not trying to be a douche, it's obvious you were looking to help. Thanks.

I honestly didnt think anyone would trust the link once they saw it was posted by a newbie with like five posts.
I really intended this to be something that would get other newcomers to quit bothering devs asking questions when theres Google.
I figured since most people don't listen, someone might as well give em something here to shut them up.....
Thank you for your kindness, though!
First and foremost, I sincerely apologize for making this type of thread, but I have done some searching and reading and I am now thoroughly confused.
My phone is the BNG3 version so obviously not towelroot compatible. After figuring out that was the case and it ain't being updated I stumbled upon Odin Pro, but it needs root to use. Seems like a bit of a catch 22.
So how do I root my S5, what is this Knox and why shouldn't I trip it, and what the heck is happening?
Once again, sorry for making this kind of thread, but I am just so confused.

I'll answer the second part since the other poster already answered the first part.
Tripping knox is just setting a flag in the bootloader to true. Basically it tells Samsung that you did something "unauthorized" with your phone and voided your warranty with them. The thing is, tmobile doesn't care. They will replace/upgrade your phone without even looking. This has been confirmed many times here and other places. (don't hold me accountable...yada yada...)

But TMB, like most carriers doesn't care about Knox and it usually won't affect a warranty claim made with TMB.

That's not always the case. Before rooting, I called T-Mobile a few times speaking to different representatives each time and asked them to explicitly describe their policy on rooting and Knox, and how it relates their JUMP! program (T-mobile's warranty/insurance and upgrade service) with regards to upgrading and general insurance repair/replacement.
EVERY SINGLE ONE OF THEM SAID: If the Knox counter is tripped we will know/find out and you will no longer be eligible for upgrading nor replacement in accordance to the JUMP! program. In fact, a couple of them went into further detail that I could be liable for paying the full remaining price plus a fine if I were to attempt to upgrade/replace a Knox tripped phone.
THAT SAID, the employee that I bought the phone nonchalantly remarked when I asked him about rooting the phone with respect to the JUMP! program that T-Mobile would honor the JUMP! program despite root. HOWEVER he said nothing about a Knox tripped phone. Perhaps he equivocated meant that a towelrooted phone may be accepted but a full-fledged Knox tripped phone may not.
TL;DR:
T-Mobile representative/"official" web-sources say Knox tripped phones will not be eligible for the JUMP! program.
ONE employee at a T-Mobile store seemed to be willing to accept a rooted phone with regards to the JUMP! program.

I'm sorry if I'm coming off as a troll/unwise, I am being completely serious. I am a cautious guy, and I wanted to know the full potential hazards of rooting with regards to their warranty policy. Of course on a person to person basis it should be easy to find a rep that will let a Knox tripped phone slide. However, in my personal opinion to pay the price of the warranty + full price of the phone + a fine in the unlikely worse case scenario that T-Mobile holds their policy to the letter seems expensive, especially when I know I will more than likely keep the phone for 2yrs+. My conclusion was to not buy their warranty, root, and be happy.
..
Just do a deferred trade in then when you jump. You skip one person looking at your phone and the people in the warehouse honestly couldn't care less.
Wow, thanks for the massive amounts of information folks, truly.
A couple question though.
1. If I Install an older version and root using towelroot...
Would I be able to keep my device up to date with the performance updates Samsung releases?
2. These custom recoveries/kernels that would trip Knox? What do they mean and what advantages do they have?
3. If I do end up tripping Knox, can I un-trip it?

I'm not sure on the first one, so I'll let someone else answer.
The reason I chose to use the root method that tripped knox is I knew I was going to flash a custom rom later on. I would really recommend flashing the CM11 rom in the forum. If you wait a few days, most if not all the bugs will be ironed out and it'll be just as stable as stock.
As to what they mean, recoveries are what you use to flash and backup roms (they can be used for more, but this is what most people use) and kernels would just add MUCH more control over the inner workings of the phone (performance, screen calibration, button tweaks, etc).
..
Last question,
If I root using an old kernel would it be possible to install updates without breaking root? Someway to keep the kernels just get the improvments?

Yeah if you call them and ask they will tell you that ... Its completely the opposite of what happens when you bring a knox tripped phone in for an upgrade or whatever .. Think about it ... If you have jump then you have premium handset protection which means you can throw your phone at a wall and take it to tmobile and get a new one . They would way rather get a knox tripped phone that they can resell without having to pay for parts or anything like that ...I have been using tmobile for years and they never ever check for know . Knox voids the manufacturers warranty not the handset protection. The sales people really don't know jack about anything . There only fix for anything is to do a factory reset . At the end of the day Tmobile wants you to have a device so they can give you a bill monthly . Its bad business to take away equipment that makes you money . Im saying this from personal experience and basic common sense . Plus I have a friend that worked at tmobile for some time . When I bought my GS5 I rooted it while I was still in the store waiting for them to finish my transaction and even showed the sales guy how towelroot works . Jump is kinda a waste anyway cause you have to have half your device paid off to JUMP , when you can just sell your phone outright to pay the other half off .Especially if you buy flagship phones . I sold my GS4 for 320 which was more than what Jump would have covered
I like this!

Fair enough and I appreciate the elaboration. You described yourself as cautious which is fine. It's an individual choice whether to rely upon common practice or only trust what is official policy. You can decide what is best for yourself.
My perspective is that life is nothing if not learning to read between the lines. Have you ever read the back of a movie rental contract? Or car rental.. or rent almost anything contract? If you took the worst case, they have the right should you ever be late in returning the rented item to literally bust down your door, retrieve the rented item and not be held responsible for damage to your home. Not to mention collect hundreds of dollars in penalties for "being forced" to repatriate their overdue rental.
It would be naive to think that is common practice or likely to happen though. And that is the lesson of worst case scenarios. It's wise to know about them, but you also have to make a judgement as too how likely they are to occur. The alternative would be to refrain from doing many common place activities and live something like a hermit.
There is no reason that you or anyone else need agree though. That's just my take on it.

Not the old JUMP. That lets me upgrade twice per year without having to pay off 50%.
