[Q] just received replacement S4.. questions regarding knox - T-Mobile Samsung Galaxy S 4

Phone was lost, just got replacement this morning.
My last S4 had been rooted running custom firmware for months w/o issue.
Read through a bunch of threads, ranging from the opinion that the bootloader change + knox wont be a big issue to the sky is falling.
Is it recommended to root my phone at this time, I do have JUMP and would be replacing it once something better comes out? The phone is running 4.2.2, caught it trying to update to already.
Thanks.. I know this may seem redundant but haven't been active on these boards since I got my CFW going. Not seeking help in flashing or anything.. just advice

Up to you. If the stock rom is bearable and you wanna run the 4.3 stock rom then by all means, go for it.

Being that your'e using the T-Mobile M919, the whole KNOX bootloader situation doesn't pertain to you as long as you're sure you're on 4.2.2. Root it, flash it, theme it with Hello Kitty... whatever, it doesn't matter; you can still revert back to stock and reset any tripped counters. 4.3 is when the problems begin and the KNOX counter is implemented and can't be reset.

I second this.
SO LONG AS YOU ARE ON 4.2.2
- You can root flash do whatever, theme with hello kitty or barbie xD like lordcheeto said or keep it stock
- Install recovery and flash away.
- Will always be able to revert back to 100 percent stock
TAKE 4.3 UPDATE
- I think you are still able to root it without tripping knox counter. Can't remember the last status of that was. But as long as you root it without a custom recovery, i think you are ok. From what i can remember, the bootloader checks the recovery status and trips the knox counter based off the recovery that is on the device. If its different then stock, it trips. But double check with Google about this first.
- If you trip knox counter, you will NEVER (as of now and possibly forever) get it back to zero.

Rooting with safe root won't trip knox and also disables it. But recoveries, kernels, roms, etc will trip the flag

Root it with chain fire and never look back.
You're on 4.22, so you're golden. Just flash a rooted stock ROM that's on 4.3 and you'll avoid Knox.
I'm running 4.4.2 and never seen this Knox stuff.

Correct. I've rooted my my second GS4G on 4.3 MK2 and it did not trip the KNOX counter. If you're still on 4.2.2 MDL, then there is no need to update your bootloader. Simply flash ROMs through recovery and flash the 4.3 modem. You will have the goodness of 4.3 on KNOX-less 4.2.2 bootloader. :highfive:

ROOT de la Vega now available for T-Mobile Note3 :)

So... after first being impatient and buying a T-Mobile Note3 on Craigslist to use on AT&T and then later seeing how the bootloader locked AT&T Note3 was rooted by DG and Chainfire I ended up getting a contract renewal with AT&T after all and went with the AT&T Note3.
Now I thought I might try to experiment a little and see if I can replicate that root method on the T-Mobile Note3 because it's so brilliant and doesn't trigger the Know warranty void flag.
I can confirm it works just as well on the T-Mobile Note3 !!
ALL CREDIT for the method goes to DesignGears and Chainfire! The Original Thread is HERE: http://forum.xda-developers.com/showthread.php?t=2474422
All steps are exactly the same. THIS IS ONLY FOR N900TUVUBMI7 firmware, so that must be the current one installed on your phone.
Please follow all steps in the original AT&T thread, just skip the oneclick.exe and start with flashing the root_de_la_vega.tar using ODIN.
There is not really a need to so this if you already rooted with the AutoRoot method and triggered the Knox flag. This is for the careful guys who have NOT rooted yet, only want root (no custom ROM or recovery) and would rather like to preserve that Know Warranty 0x0 Flag
Link to the needed file for T-Mobile Note3 is HERE:

Nice! If I wanted to go stock again, can I just flash the stock firmware in odin and it wont trip the knox flag?

Unfortunatley, once you trip the Knox Flag you can't untrip it - doing Odin to Stock will return you to stock but it does not remove the Knox flag...once it's tripped - it's tripped.

Oh no I haven't tripped my Knox flag yet I was asking if I use this method to root and I wanted to go back to stock later down the road, Will I trip the Knox flag if i odin the official stock firmware?
Its good to have this method available for those who are very conscious of Knox falg/warranty. Personally:
I will be doing a full root on my second N3. I have to; in the memory of my first N3... RIP where ever you are now.

I am not positive - but I think if you flash anything - it will trip it - if you odin back to stock - it would include a new kernel and that would tirp the flag - I may be wrong - but I believe I read this the other day.
WHy would you want to return to stock? To return the phone or something if something went wrong? Maybe there is another way to remove root.?
I dont think you even have to remove root. There will be now ay to tell if you are rooted using that method. Unless you use app that ask you SU permission. So before return just do Factory Reset. That i think should take care of things. IMHO.

No, if you ODIN back to full stock or do a factory reset/wipe the Knox flag will NOT be triggered. That flag only triggers if you install a CUSTOM recovery or kernel (custom rom).
For the Galaxy S3, there's also a "no trip root" thread where you simply flash a root-injected TouchWhiz, which I used, and as long as you never flash anything non-Samsung in ODIN, you'll never trip the flash counter flag (which can be reset with TriangleAway anyway, unlike the KNOX flag afaik). But, once rooted, you don't need ODIN, and flashing TWRP recovery via the GooManager app (or dd'ing the img over the recovery partition) doesn't trip the flag, nor does subsequent ROM flashes from recovery over the system partition.
Is it the same situation here, or is the KNOX flag different, in that it will always get tripped as soon as it sees an unsigned partition on bootup?
Darn.. Wish I came upon this like 2 days after I had my TMO note 3. Ive already tripped my Knox. Oh well.
Has anybody tested this method. Does it work

The one thing that will eventually have me tripping my Knox flag is if a nice custom kernel comes along. But until then, a simple way to root without tripping the flag will hold me over :fingers-crossed:. Also I'm returning my phone in a week so it's important I don't trip it right now. I want to root and play around with my phone until then.

Just rooted via this method. It worked fine and knox is stil 0x0. It also didn't factory reset my phone like I thought it would, I'm going to do it anyway, but I wasn't getting any FCs or anything either. Thank you for getting this out to us TMO users!
I don't get it. Rooting doesn't trip knox regardless. But flashing a custom kernel or rom does. So what is the point of this method if it will trip knox as soon as you flash a kernel or rom anyway.

For one you can use apps that require root. Also, you can uninstall bloatware and push apks to your phone using adb etc. A little more work than flashing a prebuilt custom rom, but you can get many of the same results.
*You also said rooting doesn't trip knox regardless, but it actually does unless you do it via this method.
Just did this. Easy as cake. Now I just need to sim unlock my note to use my ATT sim and I will be good to go!!

I know you don't need a custom rom for some things. I run stock deodex myself. I flashed custom recovery immediately after root. I guess I thought that is what triggered knox. Either way matters little to me though. I know tmobile won't check knox counter if I use jump and even if they did I could sell on ebay and come out ahead. So I don't really understand why people worry about it. Insurance covers it if you damage it or need warranty service.

Yeah... Seems to me like a kinda-sorta placebo effect or simply one of those things that people can use who *must* have everything completely untraceable to the "T." Like you said, there's virtually no "real" reason this is very necessary, far's I can tell... But, regardless, good work on this - without a doubt - and definitely always a big "plus" to have multiple working methods! :good:

If people read up on how KNOX actually works, there wouldn't be so much confusion.
The KNOX WARRANTY VOID flag is set to 0x1 when the bootloader detects (via Qualcomm SecureBoot) that you are booting either a kernel or a recovery that isn't SELinux enforcing (it displays a message such as RECOVERY IS NOT SEANDROID ENFORCING - Set Warranty Bit: recovery). It remembers that the partition you booted was insecure and flags it in its own little memory area. It sets individual warranty bits for each partition - boot (kernel), recovery, cache (if you happen to put something there that it doesn't approve of), system. If ANY of those partition warranty bits are set, the KNOX WARRANTY VOID flag is set to 0x1.
This is all explained in the KNOX white paper available on the Samsung web site.
Now, if someone figures out how to write-enable the protected flash area so the flag can be reset AND disable Qualcomm SecureBoot so that it doesn't set the flag over and over again, we'll be in business. For now, only Samsung knows how to do it.

[Q] "Knox" firmware and the m919 version?

I have read (<here> and <here>)
about new firmware versions that will not allow resetting the counter (warranty flag) to initial conditions when restoring to stock after after unlocking or rooting.
If the phone developed a hardware problem, warranty repair could be denied.
The firmware version "MGG" and beyond are reported to have this problem.
Questions:
Does this also apply to the m919 T-Mobile version?
Has anybody seen it on an m919?
Is it going out with an OTA update?
Or is MGG specific to the i9505?
I am shopping for a GS4 m919, and I want confirm that it has the "pre-MGG" firmware version before purchase.
Questions:
Is the ID contained in the "Baseband" ID string in the phone information?
Are there different identifier strings used on the M919?
The T-Mobile S4 has not received the KNOX Bootloader, it will most likely come with the 4.3 update. If anyone is on stock, I would recommend you guys disable OTA updates as you may get automatically updated to 4.3 with the KNOX bootloader.
for once...im dreading an update from tmobile
If I've already rooted and installed a custom recovery (Clockwork Mod), and nothing else, does anyone know if the 4.3 update with KNOX will still be usuable? In other words, will the phone still get an automatic OTA update and will that update install correctly?

It wont let you get the update it will pop a box up saying unable to uodate your device has been modified. . Try to check for an uodate youll see what im talking about... I went back to stock just to see if there was anything for updates which there wasnt andbwent to reroot and installed su abd it didn't flash correctly thru odin said to heck with it till the am checked for an update for giggles in the am and wouldn't even check

i'm glad I read this thread. i was going to wait until i tried the stock 4.3 update before deciding to root and install custom ROMs. With KNOX coming, I'm just going to root ASAP. I like PA on my Nexus4, so I'll probably go with that for my S4.
So you guys are saying the new update with "knox" won't allow you to reset the counter and only that or will it stop you from completely rooting and installing custom roms?

Let me clarify some things. The KNOX processes and functions are already on the stock ROM, most devs remove them, though. So many of you with custom ROMs haven't seen anything related to KNOX.
What the new T-Mobile update (when it gets pushed out) is most likely to come with is a "KNOX Bootloader" which will introduce a thing called "KNOX Flag" which is similar to the old counter we're all used to. This is the counter that @Chainfire was successful in resetting with his app, Triangle Away.
Unfortunately, @Chainfire or anyone else for that matter, has not been able to reset the KNOX flag.
The KNOX flags is this:
0x0 = You have not tripped the KNOX flag.
0x1 = You have tripped the KNOX flag.
Again, once you trip that flag, rooting, flashing a custom recovery, etc.. there is NO way to reset it as of now. And any KNOX functionality on your phone will not work. But the worst part is Samsung will refuse warranty on your device if they see a 0x1 in your bootloader.
Another thing.. on the new bootloader, if you try to downgrade, even with an official Samsung firmware, it will fail and you will trip the KNOX flag.
So once you're on the new bootloader, there's no going back.
There's been speculation that there's an eFuse at play here.
Anyway, this is the reason why I am suggesting you all disable OTA updates and wait until a ROM is built without the new bootloader and all the functions (Wifi, MMS, etc.) are working.

Hey, its sammy we have to blame for this one :/ Not T-Mobile lol.
PSSSST! Don't let them know you are dreading it, or they might put it off longer xD
As to the OP.
The KNOX Warranty counter is rumored to be what is called an eFUSE. If this is true, then resetting the KNOX warranty counter will be impossible without taking apart your phone and replacing that specific eFUSE.
However, there are rumors that some root methods DO NOT trip this new counter. Is that good? Yes, is that bad? Yes. For those users who like stock kernels and just wanna root, this is okay for them. But for 99.999999 percent of us who love to flash new kernels and get more from our devices, then it trips the counter.
I personally congratulate Samsung as well as hate them at the same time for this. I congratulate them because what seems to be happening a lot is users flash a million and 2 things to their device having not one single clue what they are doing, thus bricking their 500+ dollar smartphone then claiming it as a warranty claim and getting another one. I also feel they are trying to flex their ego muscles too -.-
I also believe that if you have insurance, this does not apply. It is only for warranty claims. Which like you stated OP, it only means Samsung can choose to deny to repair or replace it. I have read a lot of thread before where users tripped the older binary flash counter, and still were given a new device. I honestly don't know how this is going to play out for the lot of us. For me, my warranty is over in a few months anyhow so i don't really care. But its still kind of a dickish thing Samsung is doing.
I am also hoping that we can extract the contents of the new update and keep our older bootloaders and create a flashable zip with the new update stuff and have it still work. I know there were some issues with the international S4 4.3 update but im not sure if it was entirely caused by the bootloader.

Where do you disable OTA updates on a stock S4?
Hitting "Software Update" takes me to a Boolean"Update Now" popup with no other option than choosing Yes, No or Wifi. No option to defeat future updates is offered.
Going into developer mode doesn't seem to add any pertinent options either (correct me if I'm wrong).
Clearly, Samsung doesn't want us to be able to disable updates unless or until we root, which I'm doing this weekend on the basis of this thread.

You indeed have to root to disable OTA updates.
Once the update hits im going to extract the system.img to get all the files.
Then explore where all of the Knox crap is and get rid of it.

[FAQ] KNOX and you

[SIZE=+1]There seems to be a lot of confusion and misunderstanding circling the forums with regards to Knox and the 4.3 OTA.
This is an attempt to clear things up[/SIZE]
UPDATE: It seems that people can find this thread, but are unable to actually READ the information presented. The most important note here is that if you are on 4.3 firmware, you can flash ANY rom you like. No, you are not tied down or locked into stock only or 4.3 roms only. AOSP roms will work fine as well. Now scroll down and READ EVERYTHING IN THIS FIRST POST.
What is Knox? Knox is both a firmware and a software component. The OS has Knox apps, and the MK3 bootloader has a Knox component too. Having Knox apps does not necessarily mean you have the Knox bootloader, or vice-versa.
How does Knox work? Because Knox is both in the OS (apps) and in the firmware (bootloader) it works in two ways. The OS components prevent attempts to obtain root access and make rooting with these Knox apps a pain in the butt. Fortunately they can be removed. In the firmware component (bootloader), Knox works to prevent the flashing of custom kernels and recoveries. If you flash a custom rom or custom recovery WHILE on the Knox bootloader, your Knox flag will be tripped and your Warranty Bit will go from 0x0 to 0x1. The Knox bootloader cannot be downgraded to, say, the MD4 bootloader because of special protections built into it. If you attempt to downgrade it, your phone will instantly brick.
Can I get root on the Knox-enabled update? Yes. For those of us who DID NOT take the official OTA and DO NOT have the Knox bootloader, we can get root on 4.3 by injecting it and removing the Knox apps. For those WITH the Knox bootloader, you will need to wait until a full stock MK3 tar is available, which we can then use to make an Odin-flashable MK3 stock rom with root injected using the de-la-vega root method.
Can I downgrade while on 4.3? You can flash roms no matter what Android version they are. That is perfectly fine. But you cannot downgrade the bootloader if you have the Knox bootloader, or else it will cause your bootloader to become corrupted and give you a fancy paperweight. Again, for those who DO NOT have the Knox bootloader, you needn't worry about this/downgrading firmware since the Knox bootloader is what prevents you from doing this. Downgrading your bootloader includes: attempting to flash full stock tar of software versions < MK3, etc.
How can I tell if I've got the Knox bootloader?
Boot into download mode (through custom reboot menu, or by powering off then holding Power+Home+VolumeDown and then VolUp when prompted). If you see a line that starts with the following, then you've got the Knox bootloader. I will insert a picture showing how it actually looks soon

No way to remove bootloader Knox ATM.
I've seen several posts mention "tripping KNOX" or "voiding KNOX." What does that mean, exactly, regarding rooting a phone? Does it just mean it voids the warranty if you need to get support from Samsung/Sprint? Or are there other adverse effects?
Mostly just a visible warranty void.
Samsung bought crapple disease. So sad, but its my excuse to buy a nexus.
Sent from my SPH-L710 using xda app-developers app
As said above, a voided Knox is mostly just a highly visible warranty void. Your local Sprint store may or may not care, or the specific Samsung rep that you deal with may not care, but it's easier just to not have to deal with it to begin with.
Does this mean there is already a touchwiz 4.3 ROM we can flash or do we still have to wait?
Sent from my SPH-L710 using Tapatalk
The biggest thing here is the fact that there is no full tar file to restore. So even if you do not care about knox or warranty. If something goes wrong with a flash or anything else you can't use an older tar file let's say MD4 or LJ7 or anything because you will end up with a brick. There is nothing to use to ODIN restore your device. Once you go 4.3 with Knox you have to stay 4.3 and even if you wanted to stay 4.3 and wanted to restore that there is no tar file at this time.
Have a great day!
I have a question I think we talked a bit about the problems the knox bootloader brings into the system. My question is the opposite what does it fix / change?
Im thinking along the lines of somebody modding the update so an old bootloader would be with the new rom would that be an issue? I think i remember hearing something about wifi being the problem but any clarification would be nice.

Right now, wifi is broken with the old bootloader and 4.3 rom...happened on the other devices too (tmo s3 and sprint s4)
But there is a fix: flash at&t kernel. But it messes up screen rotation. So i'm trying to come up with another fix that will let wifi turn on properly and let screen rotation work properly too

Right now, wifi is broken with the old bootloader and 4.3 rom...happened on the other devices too (tmo s3 and sprint s4)
But there is a fix: flash at&t kernel. But it messes up screen rotation. So i'm trying to come up with another fix that will let wifi turn on properly and let screen rotation work properly too

So is this Knox a Sprint thing, or a Samsung thing?
I can understand the reasoning for Knox(money) but, dang, I guess it's a dog eat dog world out there.
This doesn't affect CyanogenMod does it? I'm scared...
edit... I remember reading about a brick api or command, I never executed it, sounds nasty, is this what they use to brick peoples phones if they try to "hack" it?

This would be a we-can't-update-the-bootloader thing lol. And we can't do that because it has Knox, which is Samsung's doing
This shouldn't affect any AOSP roms because it uses a different kernel and builds its own WiFi libs

From what I've read Knox is Samsung's attempt to provide strong security to their phones for the enterprise customers. As you can imagine, allowing system level access to files can be used to get around a lot of security measures that IT people would like to enforce in their client's devices. It makes sense at the enterprise level, but it's a pain for anyone who want's to mod their phone.
So I think the answer to your question is, unless you are using your phone in a locked down corporate environment then there really is no advantage to Knox. Too bad it can't be turned off, at least not officially.

[Q]Flashing Stock Rom

Hi.. i'm new to android and samsung things
that's why i'm here to ask something and hope could get a fast reply
Problem:
I have a note 2 N-7100 with 4.3 stock rom(unroot, OTA updated to 4.3 from 4.1.2)
I wan to know how to flash back to 4.1.2(4.1.1 if possible)(step-by-step)
done some searching over the net and all thread confused me
will 4.3 stock rom flashed to 4.1.2 or 4.1.1 stock will void the warranty(Knox)
What is the Risk i have to take?
Why i want to downgrade?
Crazy battery drain rate.. even when turn off the phone(1day about 8%)
Sometimes shuttering when hearing music
any reply is appreciate.. TQ
Your Knox flag will become 0*1. You can flash stock 4.1 through odin. But you will need to format your internal memory as well as your all apps will be deleted.

tq for the reply..
so.. i just need odin and the stock rom downloaded from sammobile
and i dont need any custom recovery.. am i right?
well the apps can be redownload
No you don't need custom recovery for flashing stock.
As joy854 said your knox flag will become 0*1. It means you lose warranty for ever and that you lose the ability to update the phone the normal samsung way.
I recommend to you that you try custom rom like hurricane or phoenix. I get more than 2 days battery with hurricane and note 3 apps.

So.. will custom rom void my warranty by trigger the knox?
Be careful!!
Hey man if you have taken the 4.3 update from OTA then you cannot downgrade to 4.1.2 stock because that 4.3 update came with Knox bootloader, because of that you cannot downgrade your phone from older firmwares which do not have that knox bootloader. It might brick your device mate, so just be careful man.

I am having similar issues with you, but i am not thinking of downgrading my ROM, You can solve the battery drain problem by downloading an app called Battery Doctor (tried putting a link here to it but the forum wont allow me since im a junior member, but you can search it out in the google play store) It is very useful and it helped me a lot. But after updating OTA to 4.3 I do get stutters when hearing music, a tad few seconds sometimes in between music. I wonder if there is a problem to solve this? Other than that. 4.3 works great on my GT-N7105. Thank you.

Yes, if you want root or custom rom it will trigger the knox thing
AFAIK flashing anything non-stock in odin will trigger knox flash counter. Root will be blocked by knox apps which can be disabled, but I don't think having root permissions itself would trigger the counter.
Personally I wouldnt care about the knox counter, so long as the issue was hardware related I would play ignorant; there's no way they can prove your device wasn't sold to you with a voided counter. That's not to say they'll validate your warranty, but with a bit of a fight the correct result would me they have to honour it - but no one wants that hassle.

Quick question about transferring all my stuff over to new Galaxy s4.

I've got a new s4 coming from my insurance plan Cuz I broke my screen.
Is there anyway I can get twrp installed without having to sit down at a computer? So I can restore my backup and have it root itself? Help much appreciated.
Search for Towelroot. I believe it will root the Tmo S4 without tripping the Knox flag. I don't think it requires a computer.
And, then once rooted you can install TWRP Manager from the Play Store.
TowelRoot will give you root. When you flash a custom recovery it will trip Knox.

What do you mean it'll trip knox? Ive never had any issues with anything called knox when I rooted and flashed on my original S4 a couple years ago when I first got it.
@The Sickness , are you saying that I WILL run into knox issues if I use this towelroot?
How do I avoid any knox issues? I don't really have access to a computer so all I'm really trying to do is get it rooted with twrp installed, without using a computer if possible. But if I have to use a computer to avoid knox issues, then let me know.
Thanks
Your new phone will come with 4.3 or 4.4.2. Both have Knox Bootloader.
TowelRoot will give you root. When you flash a custom recovery it will trip Knox. The only way to avoid Knox is to keep the stock recovery. And it will not allow you to flash custom roms.
TowelRoot root is a apk. You just run it and your done.

So your telling me there is no way to flash custom roms on my new s4?
That seems unlikely. How is everybody else flashing custom roms on newer S4s?
I'm seeing things on Google that suggest I can just uninstall knox. If I uninstall it first, then root, will I be ok? Or if I disable it while rooting?

The Knox flag is a indicator to Samsung that you've installed a Custom Recovery. They instituted the check and the flag in the boot loader for 4.3. All the new phones come with this and there is no way to downgrade to a bootloader that doesn't have the check. Unless you are using the phone on a secure company network that requires it, Knox doesn't affect you in any way. Some people have claimed that it MAY cause you problem returning your phone for warranty, but at this point NO ONE has shown that they have had any issues returning their phone with the Knox flag tripped.
You can verify your bootloader, and view the flag's status once you get the phone by going into download mode - power off the phone. Then, hold the Vol Down button while powering on the phone. Hold the Vol Down until you get to a screen that has a Warning about Custom OS. Press the Vol Up button, and you will see a screen with a very small font and the first line will say "ODIN MODE" If your bootloader has the Knox check and flag, you will see line that says: KNOX WARRANTY VOID:. Next to that line with be either 0x0 or 0x1. If the flag is tripped, it will say 0x1.
If you don't have that line in your bootloader, then you don't have Knox, and you should be able to do what you want. However, if you want to keep your phone Knox free, you won't be able to do Over The Air (OTA) updates. You'll have to manually install ROMS, and never flash an updated bootloader.
I've tripped my Knox flag by flashing TWRP to my phone and have never worried about it.

Ok tripping it just means it's telling Samsung im messing with it?
It's not actually preventing me from installing custom recoveries or roms?
I thought he was saying I wouldn't be able to do it Cuz of knox.
I don't care about tripping any flags, I've got the premium insurance plan. That's actually how I just got the new s4, by filing a claim.
That's the nice thing about insurance on these devices, messing with the bootloader and installing roms Falls under accidental damage, which is covered.
Sure the deductible is 175 dollars.... But just to replace the glass on one of these can cost upwards of 300 dollars. Worth the 11 dollars a month n deductible. I will be canceling it now though. If this one breaks, I'll just upgrade.
Thanks for the help guys.
I said if you keep STOCK RECOVERY you can't flash roms

I can read what u wrote. I thought when you guys said the knox flag would trip, that it meant I wouldn't be allowed to install custom roms.
I don't care about any flags, just so long as I'll be able to flash stuff like normal.
The SIMPLEST SAFEST and EASIEST would be to just install My Backup Pro.
it has a "Migrate" mode which allows you to send all that you wish to transfer to the new device and on that new device all you need to do is add the app and instead of "Sending" the data, just select "Receive". (takes only seconds) That way you won't muck up your warranty on the new device till you're SURE there is nothing wrong with it... (just coz it was "refurbished" does not mean it works flawlessly! :>)
Aloha and Good Luck!
Thanks for the info. But I disagree. It seems I just root with this towelroot' install twrp' and restore.
However, I'll be installing a clean rom, insane v9, and reinstalling ask my apps from scratch. Just start brand new.
This brand new S4 will last me till the "sapphire glass" S6 is released, for sure.
