Can I uninstall security updates for rooting? I want to root my Samsung device, but previously, I have installed some updates. From what I know, successful rooting depends on security bugs in the firmware:


  The process of rooting varies widely by device, but usually includes
  exploiting one or more security bugs in the firmware of (i.e., in the
  version of the Android OS installed on) the device.


But security updates are intended to fix security bugs and thus can prevent rooting or make it harder to perform. Is there a way to uninstall security updates to increase the probability of successful rooting?

Update:
Some information about my device:

Android Version: 5.1.1
Device Name: Samsung Galaxy J1 (2016)
Kernel Version: 3.10.9
What Updates did you previously install ?
What Android Version are you on ?
What Device are you using ?   

Samsung has a feature called Knox that is literally the fort knox of Androids, Root abilities on Samsung device's are rare.  

For your device, someone may have a specific method of unlocking the bootloader or even using ODIN to flash a pre-rooted firmware.  

For a successful root, it mainly comes down to...


Android Version
Device Lock Status
CPU Model
OTA Updates installed


Each area can stop you from getting a successful root.

The usual method for Samsung device's is to use Odin and flash a custom recovery, then from that you would install SuperSU or Magisk.zip files.  

I need more information to help you any further.


  Notes :
     Samsung devices will not allow you to use some feature's on a rooted device... It is why many Samsung owners end up using custom firmware like Lineage ( A.k.a CyanogenMod )
