Start up screen top left corner shows:
kernel is not seandroid enforcing
Hangs up or Reboots.
I updated my S4 to Version: I9505XXUEMKE
Then I used Odin to Flash a Root with Stock recovery & SU, something went WRONG!
Knox is now 0x1, which should not have happened, but what can I say.
BaM, I got the Reboots & Hang ups.
But, I still could get into Recovery & Download Mode!
SO HERE IS THE FIX:
1. Download, Odin 3 - THx 2 - daerragh
--- I used Ver.: Odin 3.07
2. Download, http://www.sammobile.com/firmwares/2/
--- And download your Firmware, if you know which you had before it crashed choose that one otherwise Upgrade to latest.
--- For me it was the latest version - I9505XXUEMKE ---- THx 2 -- Repulsa for the tip.
3. Start Odin 3.07 --- [Should it "FAIL" Read note at the Bottom #6].
--- Make sure - Auto Reboot & F. Reset Time are checked - Nothing else.
--- Click on PDA choose your Firmware file in my case "I9505XXUEMKE"
--- this can take a minute or two, WAIT, the PDA will check mark itself.
4. To start Turn off your phone completely ! Now hold following buttons to get into Download Mode,
--- Volume Down
--- and last Power
--- S4 will enter into DL Mode
Seeing you have already tried to root you phone, you should have you Samsung USB drivers.
5. Press Start
--- This will take time, after it Reboot itself,
--- remove the USB Cabel & wait
--- at least 5 minutes don't remember how long, I came back after 5 Minutes and it was done,
---------- so then if everything went well for you, have fun .
--- Should it Fail while uploading to your phone,
--- A. Remove Battery
--- B. Remove USB cabel
--- C. Restart.
--- Should it Fail again (which happend to me), then Do A. B. C. again.
--- and this time Touch your screen about every minute.
I Know that sounds weird, but it worked for me maybe something to do with "Stand by? no clue".
