An official firmware, Android 4.1.2 XXBMA4 Jelly Bean, has been recently rolled out to the LTE version of Samsung Galaxy Note 10.1 with model number N8020. The XXBMA4 Jelly Bean is originally for the Plus subscribers in Poland. However, it is compatible with a number of European countries. The Jelly Bean update is available as OTA and in Kies.

The Galaxy Note 10.1 LTE users, who have already upgraded their devices with the latest official release, may follow the guide below to root their devices. IBTimes UK reminds its readers that it will not be held liable for any damage to the device. Users are advised to verify the model number of their Notes since the root file works only with Samsung Galaxy Note 10.1 LTE N8020, not with any other variants.

Steps to root Galaxy Note 10.1 LTE N8020 on Android 4.1.2 XXBMA4 Jelly Bean

1) Download CF-Auto-Root for Galaxy Note 10.1 LTE to the computer. Extract the zip to get a file with .tar extension under the extracted folder
