[Q] [HELP] root Knox

hi i have a samsung galaxy s4 gt-i9505 xxuemj7 with android 4.3 and knox, how can i root and install CWM?

If your root and flash recovery note you will loose KNOX capabilities and trigger the KNOX counter and you can not downgrade to any lower firmware version after that.
If your happy with the above:
Flash CF-Root as PDA in Odin:

Then download any recovery you want to use, and flash again with Odin. Most here recommend TWRP or Philz Recovery.

Rooted with cf-autoroot. Is it okay to flash custom recoveries, ROMs, kernels?

I recently rooted with cf-autoroot so I obviously tripped knox, now I want to make the most ouf this phone. Can I now change my recovery and flash custom ROMs / kernels normally? Are there any more restrictions by samsung?

Nope, you can flash anything as you have administative (root) rights now, just flash compatible stuff for your phone (like N9005 fi).

You don't need root to flash recovery/kernel/rom...That's a myth.

Yep. Rooting is just gaining Admin access within your software.
To replace Windows on your computer you don't need an Admin to do it for you, you restart and make sure it boots into the DVD drive, then you format and reinstall.
Same thing with a normal Samsung phone. You enter Download Mode (DVD Drive) -> Odin (Installer) -> ROM/Kernel/Recovery in .md5 format (Contents of new OS/partition data etc)
As the ROM, Kernel and Recovery are different partitions of the phone's SoC, Download mode can overwrite anything on there as they are independent on each other when they aren't booted.

I find I have less problems if I root first, but that's just me...

Should I reroot?

Hi,
When towelroot came out I installed it on my note 3 so I could get root without tripping knox. Last night I installed safestrap to get a custom rom without tripping knox, but when I installed alliance rom on rom slot 1 it somehow also installed the TWRP recovery and tripped knox. So now that my warranty is void anyway I was thinking about
installing another rom, just the normal way.
My question is if I should I unroot my phone first and root it the root de la vega method or can I just install whatever rom or recovery I want with my current settings/configuration? Also when I boot my phone into download mode I still get the custom OS warning, I don't know if that's a problem or should I press continue there?

Since you have tripped knox, no worry anymore on warranty. If you plan to flash new rom, you are always advised to have clean installation, meant to clean everything, else you will experience unnecessary problem. To backup your current setting, download titanium backup to make your apps and setting backup. You need to spend some time to familiarize with TB. It is very handy to help u restore previous rom settings and apps.
You do not need to unroot your current rom.

@Marcel94 :
I have never use safestrap anyway... so I have no idea how it works actually.
But... a clean installation will be good.
Grab latest firmware nd flash through odin, and go to recovery stock and do factory reset.
Then root with cf-autoroot, flash cwm/twrp.
Then flash ur rom.

Thanks for the advise guys! What do you mean with "go to recovery stock"? Will my recovery be stock again if I flash the latest firmware through odin? Nevermind, I already flashed the stock rom and got stock recovery, thanks!

You cannot currently downgrade from a knox enabled bootloader to a non knox enabled bootloader.

I followed this method and it's worked well.
I did a factory reset because my phone became not stable with time - probably because I froze too many Knox app. or install some app. I shouldn't not - and I was very surprised to constate that my phone was kept rooted.
I don't understand why. A factory reset doesn't reset the kernel at well?
Also I wanted to dd my /data, and for this I needed to umount it. When I booted in recovery mode, adb seemed not to run... I tried Odin mode too but looks the same, adb launched on my PC didn't see my device.
Of course I checked everythings and adb does work well when the phone is fully booted.
The stock recovery doesn't allow to make system/data backup... - no menu items - is this normal?
I cannot flash any custom recovery because I want my Knox remains 0x0.
Thanks for your comments,

Yes with a stock recovery your aren't able to make a complete system backup. And flashing a custom recovery will trip the Knox counter.
I don't deal with ADB, i can't help you with this, sorry.
No, a factory reset doesn't wipe kernel this would be very bad.
You have to delete every Knox app because they might cause reboots to your device.

Hello DarkTimes,
Thank you for your answering.
I don't know if deleting Knox app. cause reboots of device but freezing them for sure does!
For now, Knox doesn't have admin rights and doesn't bother me so I leave it untouched on my device...
I prefer to not attempt to delete them... because my phone seems quite stable after my factory reset...
Regards

Questions on Root / Recovery & Kernel

Hello there!
I'm new to the Samsung's world so I have few questions I hope someone can answer.
1, I am a fan of stock kernel and I noticed TWRP has a recovery and there is a No root method mentioned using Odin.
https://twrp.me/devices/samsunggalaxys6edgeplus.html
So if I flash this recovery and flash the SU will the device boot? So do I need the custom kernel to get the phone booted with custom recovery?
2, I hear we will trip the Knox in the process of root. Do I lose Knox functionality? Since I use Knox for my company apps I would like to know if I would lose that functionality ?
