    OK. My next question is... which of the CF-Auto-Root kernels for the G900i model, did you use?

    Yes, this latest one for the G900i... CF-Auto-Root-klte-kltedv-smg900i.zip

    You will need to install it using PDA in Odin. Sometimes the CF-Auto-Root kernel needs to be flashed twice. If you run into a bootloop just boot into recovery and wipe the phone's cache partition as per #1.3 of S5 Update Problems - Dummies Guide

    What's happening... (imgur album)

    It doesn't boot loop, it just stays on the screen in picture 5 forever.
    I also can't access the recovery and wipe the phones cache, it doesn't work on that screen while the "recovery" is booting, so I just put my stock rom back on it and works perfectly, but no root.

    Just pull the battery out. Then replace it and boot into Recovery Mode and wipe the cache partition. Judging from the Knox warranty, it looks as though the phone has been rooted a few times, (4), already.

    Thats the thing, I can't go into recovery, it just freezes, power button does nothing so I have to take out battery. I can get into download mode which is how I flash default on and it boots. I checked with Root checker, it says that root hasn't been installed properly.

    That is strange that you can access Download Mode but not Recovery Mode when the phone is turned off.

    It could well be that you are rooting your phone but every time you flash a stock Samsung firmware, with the stock kernel, it is unrooting it again. The next time you are back, up and running, on stock firmware, try wiping the cache partition in Recovery Mode, (assuming you can at least access Recovery Mode with stock firmware), and then try flashing the CF-Auto-Root kernel again.

    Have you owned your phone from brand new, out-of-the-box?

    No, it is second-hand off Ebay. I can access Recovery mode on stock firmware, so I wiped the cache partition and tryed to flash it again, but it still just freezes up on the "RECOVERY IS NOT SEANDROID ENFORCING" screen.

    The issue with a used phone is that you do not know what has been done to the phone beforehand. If, after flashing the root, you cannot pull the battery when you bootloop, and then boot directly into Recovery mode using the 3 button method, and wipe the cache partition, you are stuck. The only other root procedure that you could try is Kingo Root. I have never used this method personally.

    This is my post on Whirlpool. I and others have found this method the best solution.
    "On SM-G900I with 6.0.1 stock, I couldn't get CF-Auto -root to finish booting by auto or manual. So flashed TWRP with latest Odin then flashed SuperSu with TWRP. Couldn't install Xposed, so I installed Wanam and flashed a special Wanam version of Xposed with TWRP.
    All root programs seem to be working well."
    Hope this helps.

    Okay, the root worked, but the Xposed method just makes me stuck at the samsung screen
