[Q] Is it safe to OTA update to 4.3 on my rooted phone?

So I rooted my phone using the method outlined in this thread here:
http://forum.xda-developers.com/showthread.php?t=1771687
I used odin to flash the 4.1.2 T-Mobile image and I stopped at the part that said "If you just want a stock, rooted phone with no custom recovery, no plans to flash custom roms, etc. then you can stop HERE" because I only wanted root so I could fix the keyboard bug (keyboard would revert to stock one after resets).
So my question is, can I update to 4.3 via the OTA update that is in the About Device > Software Update section in the phone? Looking elsewhere the official instructions say that the phone should not be rooted before updating. If so, can I get rid of the root in order to update? (As far as I know, the keyboard bug doesn't exist in 4.3 anyway so I don't think I need the root anymore). If not, how can I update to 4.3?
Lastly, and somewhat unrelated, can I use the factory data reset in the Back up and reset section of the settings? Previously in my experience with roms, this would lead to a boot loop but I'm not sure if that is the case with this so-called rooted stock rom.
Thanks in advance.

You can use OTA RootKeeper to temporarily disable Root so that you will receive the update. Or you could also visit the Root66 thread you have linked. There you will see Rooted version of the 4.3 update.
Having said that, You will want to Research the consequences of the 4.3 Stock update. In particular you wish to research the consequences of CIQ, KNOX and the new EFuse Bootloader.

I am by no means an expert but I figure I just did this so it may help you out. I updated my phone to 4.3 accidentally on purpose and then I decided to root my phone like the next day. I used Mr Robinson's method and then used his third method to download the ROM manager and install CWM Recovery and then I put Cyanogen on it. I have not had any issues except the app Trailer Addict doesn't work with it but that is not a big issue. I have everything else that I wanted and more. I don't care about the flash counter since I am not under warranty. Oh and you can use Titanium Backup to back up your apps. I didn't do this the first time so I had to back up from Kies 3 by dragging files onto my SD card and not all worked. I hope I helped a little.

[Q] Root De La Vega on T-Mobile Note 3 question.

Hello,
Seeing how future updates to the Note 3 supposedly causes the knox warranty void flag to be tripped for rooting with RDLV... Is it a good idea to root our devices now while we can? As in, rooting before one of these updates will both keep root on the device and have knox warranty flag 0x0 after updating to kitkat?

Bumping! I suppose it would be easy for Samsung to release an update that triggers knox counter if root is detected... I've never rooted a device though. So my question is do phones keep root when you receive an android update?

If you are rooted, you normally don't want an update over the air. There so far have been no updates to the T-Mobile version of the note 3 though.

Well I was wondering about that as well. I keep reading that the Tmo Note 3's bootloader is unlocked. If it is truly unlocked would it not matter to take updates as we should be able to continue to root and put a custom recovery back on the phone? I mean i personally would wait to know if it is safe to take an OTA before actually taking it. I came from the VZW S4 which had that crazy locked down bootloader after the 1st OTA (I luckily never took an OTA and it's on the original FW). I mean I guess they can always lock down a bootloader on any OTA but why would they if it came already unlocked?

All the ota does is download via wifi or data for the update...that is the only difference... it doesn't do any extra checking or anything like that. The only thing that will happen is after the update has been downloaded it will flash your phone and then it will erase root because it will be flashing the phone back to a stock new firmware. You then would have to root your phone again.

If you are rooted and you accept an OTA or KIES update or if you Odin flash official
stock firmwareyou will lose root but you can root the phone again if you want.
Fortunately all the cwm/twrp flashable custom roms found here in XDA
all come pre-rooted and if you flash one of those you will not lose root.
Either way you will trigger the KNOX if you flash kernels, custom roms or custom recoveries.
The only two things that KNOX does is it prevents you from downgrading to an older version
of the rom and or firmware as well as the possibility of voiding your warrany if you have one.
Good luck!

[Q] Question surrounding restoring factory and downloading official 4.3 update - KNOX

Hello!
Hope all is well. First I wanted to say i'm sorry if this is a duplicate - I searched and saw similar questions, but not exactly the same as mine .
I own a T-Mobile Samsung Galaxy S4 M919 and I had rooted it and installed a custom rom. Im having hardware problems and need to return it for repairs, so I reflashed the stock system and recovery, used triangle away to remove the binary counter, and hard reset the phone. In my download mode, my phones reads "Current Binary: Samsung Official" and "System Status: Official", as well as reads official on the device status in android so all went well.
My question is this - I got notification of a push update that is going to install Android 4.3, and apparently this "KNOX" software that I do no seem to currently have. My concern with this is that i'm reading that there is a flag with this KNOX software that is easily tripped, and once done, the download mode reads "KNOX WARRANTY VOID 0x1", which therefore voids warranties. Since I was able to get everything back to completely normal, I dont want to run any more risks since my phone really needs repairs very badly. Should I bypass this update? Though my phone is 100% official now, if I do the update, will the KNOX software catch that I had rooted/custom rom'd the phone in the past and trigger the flag automatically, or do you first have to have the update installed BEFORE you try to root it for the flag to trip? Everything is 100% stock now so when I download the update, I don't think there is anything present that would trigger anything, but I don't even have this "KNOX WARRANTY VOID" line in my download mode yet so I am wondering if I am just better off being safe than sorry?
Thanks!

It won't be tripped until you trip it so you will be OK if you update it to 4.3, But I highly advice against doing so.. Just leave it as is, and return it like that

If you are having hardware issues and are returning the phone and
your phone is 100% stock without KNOX right now then why in
the world would you want to take chances with OTA updates or
any other updates.
If it was me I would have already taken/shipped the phone back for
repair or exchange instead of worrying about OTA updates.
Good luck!

Thanks for the advice! Download mode would be the only location of that "KNOX WARRANTY VOID" flag right? If it's not there, then as long as it states both Samsung Official and Official in download mode I should be good ya think?
Thanks!

Yes.. It will also show a message at boot

Awesome yep - no boot message I see either - boots just like it did the day I bought it. So I am pretty sure I have the firmware before KNOX came out - It has been rooted since the summer so I probably luckily bypassed the official update with KNOX
Thanks to all for your information! Im gonna stay away from the new firmware just to be safe until i get the phone back from warranty!

Hmm - things got even more interesting. So it seems when i reset everything back to stock as mentioned above, the screen flickering issues have now gone away and I am not seeming to replicate them in any way at all. Does this sound familiar to anyone? I was using a version of Wanamlite ROM before i reset everything. I am wondering if it was just the ROM causing the screen flicker and not a hardware defect.

[Q] Can I downgrade to remove knox?

Hi
Earlier this week, I received a notification saying that a new official Samsung update (4.2.2) was downloaded and needed to be installed.
After installing I realized that 4 Knox applications were added to the App list, and there were more counters listed in downloading mode.
Is it possible to downgrade back to the 4.2.2 that came with the phone to remove Knox?
It came with I9190XXUAMF7, and now it is on I9190XXUBNA1.
Thanks in advance

no ..and btw you should have been more careful about that .. u didnt have knox bootloader now u have ... if u flash any other bootloader or rom before BNA1 ur system will crash u cant downgrade ..also knox when turned from 0x0 to 0x1 it cannot be reverted back for now so u lose warranty if u have one

And if I do a hard reset?

Makes no difference. There's no way back.

There's no way back. If there was, everyone here trying to mod their phone and not lose warranty would be really happy and there would probably be more than one thread showing you how to do it.

Warranty - Custom Firmware

I am using Omega 29 on my N7100, but now it has some Hardware-defects and i am worried they may decline my free repairs, because of that bootloader-status thing.
Is there any way to go back to original without any indications of prior custom firmware use?
They will update my Phone to the newest available firmware, which will include Knox. I already called them, there is no way around that. Samsung forces them to do that with every single repair. Is there any way to completely get rid of knox and that knox bootloader again after they updated it?

1. Flash latest stock via ODIN. Also wipe internal sdcard in case there is any folders that rooted apps may have created, just in case they use that as excuse not to fix.
2. No.
