Android 4.3 Jelly Bean brought a lot of great features with it, but it also brought some changes behind the scenes that people did not see also. One of those was the new way of handling the request for root access called the su daemon process. The su daemon has to run at startup of the device or else it just won’t work, and there is no way to become the root user. The older of getting root access before Android 6.0 Marshmallow handled that from the system partition. However, with Android 6.0 Marshmallow software updates, there was no way to launch the su daemon during the booting process. It is at that time that a modified boot image came to fruition. The new version that handles the modified boot image was when the systemless root version of the CF-Auto-Root tool was born, and that is the version you have here—as it always is when you have a version of the CF-Auto-Root tool that roots the Android 6.0.1 Marshmallow updates.

None of the mentally challenging aspects that developers like Chainfire go through to bring you guys root access need to matter to you unless you have an interest in understanding what is happening. It does not help you being able to get root access any easier just by learning what was just told. The great thing about one-click rooting tools is that they are never more difficult or challenging than the last because all they ever take is just one click and they are complete. Thus, the way the CF-Auto-Root tool works for the Android 4.3 Jelly Bean software updates with the Odin flashing tool is still the same way that it works for the Android 6.0.1 Marshmallow software updates even though so much as changed since then.

Moreover, there is nothing different with the sheer amount of new apps available and at your disposal when you are the root user and have the root access granted over the operating system. The same apps that were available to you after you rooted using the one-click rooting tool by Chainfire for the version that did start up the su daemon process from the system partition are still the same applications that are available to you now with this systemless root version.


  • Chainfire had the MMB29M.T355XXU1BPF1 firmware build number running on the Samsung Galaxy Tab A SM-T355 tablet when the rooting file available for you to download in this guide was developed. He makes that information readily available, but it is not suggesting that you need to run on the same firmware build number before you do the flashing of the rooting file. He is giving that information so you can use it as an indicator if that information ever becomes relevant.
  • Just like all good rooting tool, the CF-Auto-Root tool has a thread set up for it over at the XDA-Developers website. You can use that thread for letting Chainfire know if one of the files needs updating. You can tell a file needs updating if you flash the rooting file using the flashing tool and yet the device will not boot up after the flashing. Before he can fix that issue, though, he also needs the recovery image file from the firmware, and he needs you to leave that recovery image file in your message for him
  • You need to have the Samsung Galaxy Tab A tablet that has the SM-T355 model number if you are going to flash the rooting file available in this guide. If you try to flash the rooting file that is accessible in this guide on any of the other model numbers that device often gets bricked, and you need to flash the stock ROM on it again to get it working.
  • You need a computer to use the Odin flashing tool that flashes the rooting file, but the only computer that can run the Odin flashing application is one that runs on a version of the Windows operating system. It does not matter what version of Windows as long as it is at least Windows XP.
