A couple question though.
1. If I Install an older version and root using towelroot...

2. These custom recoveries/kernels that would trip Knox? What do they mean and what advantages do they have?
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).

That is a lot of questions so cursory answers. You ought to do some more reading, sticky threads at least so that you have a better understanding of how everything interrelates. Not to mention that these questions have been asked and answered numerous times in existing threads.

Updates inevitably break root, so if root is important to you, you shouldn't be accepting automatic updates. We find out ad hoc what each update does after it happens. Best to watch how it affects others than be an early adopter. In the alternative, you can buy mobile odin pro or super su pro both of which have a feature that attempts to regain root after an update. No guarantees though and no one knows in advance the result.

A custom recovery e.g. TWRP, CWM, etc are full featured recovery modes that will do 100% complete backups which are invaluable. As well as provide a file browser, command line interface, permissions fix utility and other features that all work (well 99% of the time) even when something has rendered your device incapable or booting normally. Also the ability to easily install custom ROMs. Having easy and complete backups is the killer feature IMO. Soooo much better than something like Titanium. And custom kernels add a ton of features. Read the forum for extensive elaboration.

In any practical sense you have to consider the Knox flag irreversible. It's very difficult, almost impossible to reverse. Perhaps that will change in the future, but for now consider it irreversible.

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?

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.
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

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.

That right there was a lesson in life!

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