I recently updated to official 4.3 but kinda missing root features.
Now, I read in several places that once updated, we can't downgrade. Also, we can't put custom roms anymore, otherwise the device will stop getting official updates because of that knox thing.
I was wondering if anybody tried downgrading or installing a custom rom after official upgrade to 4.3 and share their experience with rest of us ?

yeah you can install custom roms; you can install custom recovery etc. Messing can reset a e-fuse or similar and void your warranty though.
I have so far been unable to root it. knox won't allow supersu or superuser to run.

I am wondering if it is possible to install a custom rom(quantum or cyanogenmod).I don't care about warranty, already tripped the Knox flag rooting. Will I brick my phone trying to install a rom? If I can how?

This gets covered a lot at XDA. Recently in the Q&A thread as Method for Root, Recovery, ROM installation after 4.3 OTA [ 1 2 3 ... Last ]
The bricking is guaranteed if your new flash includes an incompatible bootloader. The forums for each rom you are interested in are best resources.

Can i still ota with Knox tripped?

Yes you can as long as you have stock recovery.
Type from KitKat bar.
Hi guys I am new to this tablet so any advice but be appreciated.
If i update to kitkat I am told the knox security feature would be installed too.
What if I leave my note 8.0 on 4.2 and root and use custom roms and then if I decide to unroot and flash kitkat, would knox be triggered due to historic custom roms?

Pretty sure flashing a custom recovery will trip knox. No way around it. http://forum.xda-developers.com/showthread.php?t=2800290
Ok thanks what if I just root and not flash a custom rom, would this trigger the knox?

It depends on the rooting method you use. The one I used to root 4.4.2 after I updated via Odin was Chainfire's CF-Auto-Root and that tripped KNOX because it installs an unsigned (by Samsung) custom recovery temporarily before re-flashing the stock version.
I've never used Kingo but they claim to be able to root the Note 3 without tripping the KNOX flag so their method using an Android vulnerability to gain temporary root might work for the Note 8.0 as well.
My suggestion would be to use these forums and Google to research all the current methods for rooting the Note 8.0 and make sure there are users who have done it successfully with the KitKat boot loader installed and not tripped the KNOX "warranty" indicator.
Based on the KNOX articles I've read it appears that flashing, or even booting, an insecure kernel can set the eFuse switch which is said to be "impossible" to reverse, so flashing custom kernels and ROM's is out even if you can get root with the stock ROM without tripping the indicator.
I can understand the requirement for KNOX in high security environments but automatically voiding the warranty is just encouraging users to brick their devices in ways that prevent the KNOX flag from being accessed. Perhaps Samsung's position is that once the eFuse flag is set even their service centers cannot reverse it so the device is not able to reconditioned and sold since a tripped KNOX flag also disables some security features in the stock ROM.
Edit: I just read your OP again and if you don't flash the 4.4.2 (KitKat) bootloader and root with CF-Auto-Root you should be fine, even flashing custom kernels and ROM's, and still go back to a completely stock configuration using Odin to install the stock 4.2.2 ROM and TriangleAway to reset the flash counter. AFAIK there is no check of any historical data when the KNOX enabled 4.4.2 bootloader is installed but I would make sure that TriangleAway has successfully reset the flash counter before upgrading just to be safe.

I currently have my SGS 3 stock rooted with TWRP 2.7 installed. The version of 4.3 I have installed doesn't contain the KNOX bootloader. I'd like to keep it that way should I decide to later move onto a custom rom. From what I've read, if KNOX is installed I won't be able to do that. Is this correct?
I've searched for 4.4 without KNOX, but I haven't been able to find anything. Does anyone here know if it is available? I don't have any major issues with the 4.3 stock rom. I did noticed that my battery drains slooowly if I'm using navigation and it's plugged in. I think that that issue may be due to the iBolt car dock I'm using. I don't think it allows anything over 1 amp for charging.
Should I just go ahead and installed a custom rom that is 4.4?
Thanks
I believe that KNOX doesn't restrict you from installing a 4.4 based ROM, but once you have KNOX you will not be able to downgrade to 4.3 or earlier release. An attempt to do so will permanently brick the phone.

You can install any rom zip on knox as long as you do not downgrade the boot loader via tar files or any other method that flashes every part of the phone.
Thanks stopeject and oeyhdownsouth.
Hi guys, I just got a galaxy s4 for t mobile and it came with 4.2.2 version of android. I'm scared to brick the phone but I really want to root it. Can someone point me to the right direction? Been reading some tutorials but they are for different versions of android. How do I root my phone without bricking it or tripping Knox?

4.2.2 doesnt have Knox. Use CF-Auto Root by Chainfire to root.

Thanks! Now it seems that cf auto root comes with a stock kernel and recovery. Is this changeable? Can I install a custom recovery and kernel after using cf auto root? Or should I find a different method of rooting for this? Are there any safe ones out there. It seems that a lot is outdated and I'm afraid of installing the wrong thing.

I don't know if towelroot will root 4.2.2, but it doesn't install a recovery.

You're calling a rooting method outdated while using the exact "outdated" software it was meant to root in the first place. CF-autoroot is as safe as safe can be. In fact, I know it still works for 4.3 and I THINK 4.4.2; it just trips the KNOX counter on them... still gets the job done though.
As far as your concern of installing the recovery; it first flashes its own recovery so it can use an exploit, then reverts it back to stock. I believe the kernel is untouched.
If your end goal is to move on to custom recoveries and custom ROMs you can bypass the rooting process altogether and go straight for the recovery/ROM.

This.
You really don't need CF Auto Root at all until all you want to do is root the stock rom.
If you want to install a customer rom, use Odin to install a custom recovery and flash whatever you want from there.

That's precisely my end goal. And I guess my question is how to do this safely with the Android version I have.
I didn't mean the root method was outdated; I was talking about some of the information that's on the general forum regarding root. There is even a post on one of the stickies asking for updated info in May. This scares me because for all I know I can follow one of these methods to root or install a custom recovery/rom and end up with a brick because something is no longer compatible.
I guess my question is: what is the best (updated) method of installing a custom rom/recovery for my tmobile s4 with android 4.2.2?
Use cf autoroot and flash clockworkmod through Odin. Download rommanager. Download a rom. Hit install rom from SD card. Pick your ROM from downloads.

I understand your apprehension, i really do. What I've said to do has worked for me when i got the phone over a year ago, and has worked here recently when i did it again. I'm trying to tell you there is no need for an updated way of doing what you want. If you want root, use CFauto root. Like i said, that method was done specifically for MDB and MDL firmwares, there is no better choice. Newer yeah, but better? Not a chance. Your firmware is equally outdated and it's worked for millions of users without fail.
As far as a custom ROM goes, find one you want to use, put it on your SD card, pick a recovery (CWM, Philz, or TWRP), flash that in Odin, boot to recovery (power+volume up) , do a full wipe (system, data, and cache) select the ROM, and flash. No need to root at all if you want to go straight to a custom ROM.
EDIT: Obviously, you might want to perform a nandroid backup once you flash your recovery... but that's really optional as long as you have the stock Odin-flashable firmware. Totally up to you.
