Questions and Answers: (FAQ)

I should have done this before, but the brilliant idea did not come to my mind.

1. Will this trigger KNOX???

A. No it willl not trigger KNOX. KNOX is triggered by things that are not signed by samsung. eg. customer kernels and recoveries

2. Which devices are supported??

A. All those devices on which towelroot used to work before their kernels were updated. If you had rooted before by using towelroot then this method should work. Further, as for the information i have, it is confirmed to be working on G900F, G900FD, G900M, G900I and G900V. G900H(exynos version) is NOT supported as towelroot uses a kernel exploit to work which does not exist in exynos variant (sorry guys!)

3. Once upgraded to Android 5.0 is it possible to downgrade without triggering KNOX??

A. Yes is it possible to downgrade to 4.4.2 without triggering KNOX. You just have to download 4.4.2 firmware from sammobile, flash using PC ODIN, get into recovery mode and factory data/reset.

4. Rom name abbreviations and some other abbreviations??

A. G900FXXU1ANG9 will be reffered as ANG9 or NG9. Same goes for NE2. FC stands for Force Close '(i.e. application crashes with error message being displayed)

5. My device/firmware kernel does not exist in the downloads page, what should i do??

A. If your kernel is not their in the download page, download the firmware with the same kernel (eg. if your firmware is G900FXXU1ANG3 and its kernel is not their in the download page, download this firmware from sammobile) and use this script >>>>here<<<< to create a flashable kernel image. Just extract boot.img from the firmware package and use the script to create the kernel.

6. Will OTA updates work after rooting??

A. No, they wont work

7. How to disable Reactivation Lock or check whether Reactivation Lock is active?

A. Just navigate to Settings>Security>Reactivation Lock should be UNCHECKED. Alternatively, you can boot into download mode (google on how to boot into download mode if you do not know), there will be a line saying Reactivation Lock: Enabled or disabled.

8. If KNOX is 0x1 can it be reverted??

A. No, once triggered it cannot be reverted.

9. Is it possible to change device status from Custom to Official??

A. Rooting causes it to be custom, to revert it, you will have to install xposed module such as wanam exposed but instaling xposed moduel does break your s health. so there is a work around which you will have to search via google

10. How to flash old kernel??

A. Get into download mode and connect mobile to PC. Open PC Odin and select 'AP' and then navigate to the kernel file and flash.

11. How to unroot device??

A. Open superSu>settings>full unroot

12. Can I flash 4.4.2 kernel on Android 5.0 to root?

A. This does not work. Flashing the kernel will take your phone into boot loop and you will have to flash back Android 5.0 kernel

13. Which Android 4.4.2 firmwares are supported?

A. ALL

14. Will i lose my apps by upgrading to Android Lolipop??

A. It depends whether you perform full wipe or no but it is recommended due to change in runtime style. There will be huge chances that you will face different force closes.

15. Is the Android Lolipop Rom rooted??

A. Yes, its prerooted with busybox installed

16. Does unrooting trigger KNOX??

A. NO.

17. What is the difference between rooting via CF-Root and Towelroot??

A. CF-root triggers the KNOX while the towelroot does as it is based on an exploit. You will have to go through all this trouble to keep your KNOX 0x0
