[Q] To root s4 or no? - Galaxy S 4 Q&A, Help & Troubleshooting

My question is in the title of thread? So i had an xperia sp, and i unlocked bootloader and installed a cyanogenmod and i had an warranty (broke my microphone) And they gave new phone to me, i hope that they will be stuipid in services if i somehow spoil my phone (god forbid (google translate)).... But never mind for warranty, probably i will install cwm and flash new roms cause i want to make more video reviews about roms kernels etc.. Also check out my channel on youtube if you want. Whats your opinion?

Well if you want to flash roms then you HAVE to root

Best thing I did was to root & flash this phone

4.2.2 original rom should equal to no knox enabled so root away. On the other hand, if you're worried about warranty and you're on 4.3.x or 4.4.x then your warranty is lost if you tinkle with it - Knox is going to be triggered and warranty is void.
Do the math and root awayall the same , and do take care about your phone there are much more benefits from rooting it, then not doing so

[Q] Downgrading Canadian Galaxy S4 & a Q about Knox

Hello,
I recently picked up a Canadian Galaxy S4. This is my first android device after using an iPhone 4 for the last 3 years. I'm a tinkering kind of guy so when I heard about the whole custom ROM community for the s4, I was excited. I've been reading up on this for the last 3 weeks and I still have a couple questions that I haven't really seen a solid answer for specifically regarding the 1337m model.
1) If I root it would be nice to be able to reverse things should I need to send it in for warranty repair. I understand that triangle away isn't working on the latest MG1 firmware (which my device came with). I know that the ME7 update on the US version included a bootloader that no longer allowed downgrading firmware. Is this the case with the Canadian models as well? If it is possible to downgrade are there any special steps that need to be taken, or can I just flash a stock MDJ image via odin/heimdall
2) I have read the whole thread about the issues with the knox warranty void efuse. I checked the download mode on my phone and it does not have any of the knox info on it, so as I understand it, knox isn't enabled and therefore as long as I don't update to new stock firmware and I shouldn't trip the efuse. I have disabled auto-update in the settings. Is there anything else that I should do or be aware of to make sure that my phone doesn't update and force the knox stuff on my phone.
At the end of the day, if my warranty is permanently void, that's fine, but if there's a way that I can still keep the ability to restore my phone to 100% stock without tripping and binary counters or efuses I'd like to make sure that I know and understand how to do that before I start flashing custom roms rather than trying to figure it out in a panic if something goes wrong on my device.

[Q] Rooting options

Hey,
I have recently acquired SGS4 in place of my SGS3. I have used to change a rom every week, but now all I would like is a stable, rooted and .
I just discovered all the fuss about Knox and I am even more dissapointed. I really didn't want to buy another Samsung device (Exynos resources, SDS and their horrible overlay) but the offer on it was just insanely good compared to everything else to I took it.
Anyway, below are my current bootloader/firmware information:
http://i.imgur.com/G5pThnv.png
http://i.imgur.com/sl7M1VC.png
As you can see it is 4.3 from T-Mobile from november.
Now would you be so kind and tell me:
Can I root and modify my rom and bootloader on any custom without loosing my warranty?
If not, can I root and change the rom to the google edition?
If nope again, hopefuly I can at least use root with one of the latest Samsung roms? (without T-Mobile bloatware)
You live in the EU. That means that even if Samsung doesn't want to fix your device because you tripped Knox (unlikely that they won't fix it), the store you bought it from still has to fix it even with Knox tripped. That is consumer law which should also apply in Poland.
You can only root without tripping Knox.
You can not flash a recovery without tripping Knox, thus you cannot flash custom roms without tripping it.
So just root and flash the rom you want. You can even skip the part of rooting and just flash a custom recovery.
There are no downsides if you tripped Knox.

noob question

hie i moved from iphone 4s to note 4 in oct last year however kept busy so could realy get in customizing it much yet howeve now tht i do have time i was thinking of rooting it and seeing how it goes however i understand then ota updates dnt work if i root would then updating over kies with a cable b fine also i understand tht knox is tripped so no warranty after tht however say after rooting i install custom roms would the s pen and finger print scaners and stuff normally cause they are a few thing tht i do use frequently . any other cons that i shd know before rooting or flashng custom roms ?
Installing a custom rom without rooting does not break the warrenty and you will be able to use all the features of the Note 4 as you would if you were using the stock firmware. Rooting just makes you a super user and allows you to install apps which require root privilages such as Titanium Backup.
Pardon me but to install custom roms you require a custom recovery which would trip Knox?
Okay, so first of all ask yourself whether you want to use knox specific features such as secure pay (Pay by using NFC), KNOX enterprise features which an average user will not use.
Secondly, If you wish to remove apps that are pre-installed on the device as they may be slowing down the device and ruining battery life then you will have to root or install a custom rom to deal with those, or you could simply try disabling them in the app manager without root.
After rooting if you use Touchwiz based custom roms you will still have 99% of the Note 4 features still available and sometimes you get additional features which would otherwise not be available for example removing restrictions such as recording calls which maybe disabled in your region or carrier. This is just one of the many features that you gain.
So your Spen, fingerprint scanner will all work as long as you use a Touchwiz based rom.
If however you want to use the latest and greatest version of Android and enjoy a clean and smooth experience then you may wish to install AOSP roms however they currently do no support fingerprint scanner and nor do they have built in SPen features.
A custom recovery will allow you to backup your current rom and restore it later if you so desire, this backup will store you settings, apps and the current rom which can be restored if you want to return to the setup.
The only con of rooting and flashing is that you read the instructions in the thread and do no deviated from it unless you know what you are doing.
Voiding your warranty is also a potential con, however here in the UK and Europe Samsung will have to repair your device in accordance to the law and I have had my Samsung Galaxy S4 repaired multiple times with the KNOx warranty tripped; however Samsung have rejected some claims in the past for some people.
If you have anymore questions then please do not hesitate to ask.
The best advice I can give is Google till you just can't any more! Read everything you can about rooting your model of handset...then read it two more times. I've rooted a few phones now and never hit more than a simple soft brick which is easily fixed. Because I read everything I can find before I start.
Not a direct answer to your questions I know but hopefully both reassurance and warning at the same time.
On a side note if is really just customisation you want without the adventure of rooting try a launcher like nova, Go etc. You can really go wild with customisation without losing any features or tripping Knox.

Flashing Custom Rom

Hey guys,
I always used custom rom in my life, i was at Xperia Z1 and the stock was very bad... But with S6 i don't feel i need to get a custom, i enjoy a lot the Samsung work on the stock, but after looking the Miui 7, i really thought in flashing the custom rom.
So the question is... I saw that Knox and Samsung Pay will not work after the process, is there a way, later, that I can get back to original and get the Knox and Pay working again? My concern is about the security on Knox and the Pay when i sell the phone in the future, because I don't use this feature...
Thanks a lot if anyone can answer me!
Im no expert on android devices but from what I am heard you have to do a full factory reset to a stock rom and samsung pay will be enable but knox counter will still show that it has been tripped.

Is it possible to flash a custom rom without tripping Knox?

Hello,
So recently, I've encountered the same Issue I've been having for a long time with any sort of Samsung device - performance. I find my device annoyingly slow. A factory reset fixes this but then the phone bogs down.
I've decided to look into potentially flashing a custom rom to see if they're far more optimised than the stock rom. The problem is, I'm a warranty freak. I like to keep my warranty intact and modify the device later on once the warranty has gone. Obviously, the Knox flag is a thing and I don't want to trip it.
When I had my One Plus 3, I had none of this and rooting/custom roms didn't bother me as it was covered in the warranty - this is a big no no with Samsung.
I'm not so much wanting to change the kernel or the bootloader or use TWRP - just install a new custom rom to hopefully get some performance gains and maybe root too.
TL;DR Is there a viable method to installing a custom rom without tripping Knox?
I am precisly on the same situation as you are

If you have a exynos version then its impossible this moment to have a custom rom without having twrp, which in turn will trip Knox and may effect warranty depending what currently in

Dang it, I do have the Exynos version.
So is there an exploit only applicable to the SD variant?

Yep, the kind-of exploit is only on SD variant.
Although, it can be said that the exploit isn't that good as well, since you will be unable to flash custom ROM (only debloats etc IIRC).
So, they are unable to flash cutom kernel etc.
hi , what about installing custom rom with heimdall? no need for root, no need for twrp. will this triggger knox as well? does exynos/snapdragon matter in this scenario?
hey,
heimdall is only an alternative to odin, anything non samsung trips knox
Is there any way to flash an official rom without rooting to replace my actual one from my carrier? or just a way to at least change the boot screen logo?
