[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:

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.

[Q] Rooting Verizon S5 With Towel Root And Edge Program?

So i'm fairly new to the android rooting world coming from a ( Iphone 4S ). I had a upgrade so I said what the heck and I switched over to the "edge" program up to the S5. So now this phone is on the Verizon edge plan and I have questions about rooting it.
1. If I use towel root will it set off knox?
2. Will I be able to install a custom recovery after its rooted with towel root without setting off knox?
3. Will I be able to set the phone to stock firmware (for warranty,edge up etc)?
4. After the phone is on original software will Verizon and/or Samsung know if it was rooted?
5 How would I set it back to stock firmware if I use towel root?
6. Anybody root a S5 that's on the Verizon edge up program?
I would like to avoid setting off knox
Thanks fellas I know I sound like a full on N00b lol. I look forward to hearing back from you folks.

There have been 76,104 posts asking these questions, so consider doing a forum search next time. Not only would you get a faster answer, but existing threads are a wealth of useful information.
Towel root has not incremented Knox in the past. However a recent OTA update - if your phone downloaded it - blocks the Towel root exploit. The workaround to that is to use a program called Odin to install an older, pre-update (pre June 3rd) version of the firmware to the phone. Then Towel root will work.
Most carriers do not lock phone bootloaders. Verizon is one of the few that does. This means that you cannot install a custom recovery or kernel directly. You can use the Safestrap program to emulate a custom recovery though. Attempting to install a conventional custom recovery may increment Knox.
Accepting any OTA firmware updates will likely deactivate root on your phone, meaning that it would have to be rooted again.
If you completely remove root and install stock firmware on your phone, the carrier should not be able to tell provided that you have not incremented the Knox counter. Knox is, in practical terms, irreversible. You aren't going to be able to decrement it anytime soon.
If you read the forums, you'd learn a lot more about your phone and the options available.

Hi fffft thanks for your reply I really appreciate it. I wasn't sure if Odin would set off knox. I have rooted and installed custom OS's and recoveries a lot of galaxy/android phones in the past but not on a Verizon Android/ S5. Wasn't sure of the procedures were any different. I have read a lot of threads pertaining to this subject before I even started this thread and I have learned a lot on the new S5. I just wanted to get my "specific" questions answered. I'll be sure to research a little more before I start new threads. Thanks again.

[Q] Need help/ couple questions on rooting GS5

hello, well first off Ii recently got the GS5 about a month ago and i must say i love it! Such a big change from my iPhone 5 and couldn't be happier. Now that i have decided I want to root there is way too much information to look through that it is overwhelming (so i apologize for the million times this question has been asked) and I am fairly new to rooting have had an iPhone for 3 years and was pretty capable with jailbreaking. Although, now getting to rooting I am pretty clueless beside the fact that my kernel which is the one from july 22 can not be rooted with towelroot. So now onto my questions:
How exactly can i go about getting the appropriate kernel to root with towelroot so i do not trip knox, even though I am not too sure what the purpose of knox is? And if i decided to not care about knox and go with custom roms what benefits would i get over staying stock rooted?
After rooting what are some key apps to download beside greenify and the xposed apps?
Finally not really much of a question but any other advice/tips would be greatly helpful and appreciated,.
Some info on my phone:
Kernel Version: 3.4.0-278781 July 22
Build number: G900A
Thanks.

Flashing An older stock kernel doesn't trip knox flag.
Furthermore, is a must if you want to root tour phone due to samsung to hace patched the latest kernel vulnerability.

Galaxy S7 Verizon (SM-G930V) Pre-root Questions

It's been a while since I've had a Samsung phone, but I recently purchased this S7 second-hand specifically since there is a root method for this phone. I've been reading up for a week, but before I dive in, I'm hoping some of our knowledgeable folks here can help me avoid any irreversible mistakes.
The phone is currently on 6.0.1, October 2016 security update. Is there any reason i shouldn't update to 7.0?
Assuming I do update to 7.0, should I do it first (before root), or do I just flash the engineered boot and the firmware I want? Can I downgrade to 6.0.1 after going to 7.0 if I choose?
I understand there is no custom recovery available, but that I can use Flashfire. Is there any way to use Magisk instead of SuperSU?
Can I use Xposed?
Will altering system in any way trip KNOX? Is there any way to delete system apps (instead of disabling)? Can I move a user app to a system app? (This is the primary reason I'm interested in Magisk, btw.)
As I said, I've done a lot of reading, but couldn't easily find definitive answers to these questions for this particular phone. Any help would be greatly appreciated!

Same Questions, essentially same reasons...

In your reading, and posts/ IRL that have come after yours, have you come up with answers to these questions? I recently fell into one of these phones also on VZW, and am not used to locked everything/ bootloader.

You have discontinued roms that run on 6.0 but other then that there's no real difference in the 2 other then you can't hoo back to 6.0 once updated
