I updated my phone today and I was able to root it an disable KNOX.

I used CF-Autoroot http://autoroot.chainfire.eu/ and it worked flawlessly and when I was updating the binary I got the option to disable KNOX.

Root Instruction:
1. Flash with Odin
2. Add a google account incase it has not been setup yet.
3. Install SuperSU from Market.
4. Open it and it wil ask you to update binary.

Respect to the developer.

Futhermore, I got CWM with one of the methods I was using when on JB 4.1.2

PLS NOTE: You will lose warranty if phone is rooted at this time. If you will like to keep your warranty with no possibility to go back to an older android version, please AVOID rooting your ROM and wait for custom ROM with KNOX disabled

Cheers,

But.. I don't know whether to use the i9305 or I9305T files :/

My device is I9305T but has been running I9305 FW (and probably bootloaders) for a while...

For those who need some more links/instructions:

Backup your data, SMS, settings - and make sure you got an IMEI backup

If you use Google's 2-Step Verification, make sure you can receive the SMS via a 2nd phone or have a backup option like landline or authenticator app.

I removed my SD card (just in case) and did a full system wipe just to get rid of everything I did to my system over the last year:
Hold down volume up, home and power buttons, when screen turns on, leave these buttons, do the full system wipe. (Don't think this is really necessary though.)

Install 4.3 on your i9305

Switch the phone off after first book (at SIM PIN prompt).

Get CF-Auto-Root and install it

Now after your phone booted you can run the Samsung setup. Add your Google account.

Install SuperSU from the Play Store - not SuperUser

Update the binary and disable KNOX

Enjoy :)

For me what worked, was installing PhilZ Touch (latest version), and using the built-in rooting function of the recovery. Then, installing SuperSU gave me perfect root.

Does anyone know if Koush's superuser app works in any way in this release? I would prefer to use an open-source superuser app.

Did you mean to link the [GT-I9505 + GT-I9505G] CF-Auto-Root page, or should we get the file from [GT-I930x/T/N][SHV-E210*][SHW-M440S] CF-Auto-Root?

Update using Heimdall, and skip flashing tz.img and sboot.bin. Be aware that this will break WiFi until a custom kernel is released

Thanks for sharing this interesting experience.
But I think it would be kind of you to edit the OP to say in a very visible way that someone doing that looses his warranty with no possibility to go back at this time (until a solution is found, but no one knows if this will ever be the case ...) because of the new Knox bootloader and the new Knox warranty void flag.

Thanks mate for clarifying the issue of Knox flag and warranty. I will wait for a dev to make Knox-free rom.

if you'd like to have 4.3 stock rom with root and warranty, you can update your phone to 4.3 using Mobile Odin PRO latest version (3.85). Let's say you're on 4.1.2, just download 4.3 for your phone, move it to phone storage, flash it using Mobile Odin PRO with EverRoot and Inject Mobile Odin features. This way you'll have a 4.3 rooted in warranty.

Thanks for pointing that out. I have updated the OP.

For sure?
I've buy the Pro Version ( in this moment the version is only working with this Mobile ( nobody knows, at which time the support will be stopped :confused: ) ).
I don't want see, that Knox is incr. from 0x0 to 0x1 with this procedure ....

I think I've read that Mobile Odin isn't able to flash the bootloader. If this is really the case then it is true (old bootloader = no Knox flag). Note that you will also need to flash a custom kernel cause stock 4.3 kernel without Knox bootloader breaks wifi.

    I will try this tonight!

    Update: this is not working with me. SuperSU cannot install binaries. I just lost my time. Does this work with somebody of you? Please share.

    I have updated my i9305 to 4.3 a couple of weeks ago. I have a KNOX app, but when I click on it, it says I have to download something. Is it still safe to root my phone at this time since I haven't downloaded that KNOX thing? Thanks! :eek:

    Sorry I have to tell you this, but you and I are on the same boat. You may not have the Knox software, but you've got the knox bootloader, which sucks. Can't do much more than wait and hope for someone to find a workaround.

    Cheers,

    Actually, sorry! If you're just looking to root your phone, apparently it is possible without tripping Knox to 0x1. Look around the forum, the answer is probably at hand, but there's no way to downgrade.
