With the roll-out of latest version of Jelly Bean, Android developer community started releasing custom builds for the first generation Galaxy Note, which is currently running on Android v4.1.2.

Samsung Galaxy Note
The Galaxy Note is currently running on Android 4.1.2 official firmware.

Note users who lost the warranty of their devices during rooting, to install custom firmware, may now reclaim warranty back by unrooting the device. Users can also reset the binary counter, which increases with the installation of custom recoveries, to zero. Information on resetting binary counter comes from recognised XDA developer, ashwin123.

Users looking to unroot their Galaxy Note (GT-N7000) to stock official firmware may follow our guide (courtesy of The Android ROM).

IBTimes UK reminds readers it will not be held liable for mishaps. Users are advised to ensure their handsets meet following requirements.


  • Install USB Drivers for Samsung Galaxy Note to transfer files between Android device and computer
  • Enable USB debugging mode on phone to connect with computer and use Android SDK [Press Menu > Settings > Applications. From there navigate and click on Development and ensure USB debugging mode is turned on]
  • The tutorial might wipe out all data, so create a backup. If the device has a custom recovery like ClockworkMod/TWRP already installed, then backup data using that recovery
  • Phone should be rooted; click here for a step-by-step guide to root Samsung Galaxy Note N7000
  • Device should be factory unlocked and not locked to particular carrier
  • Verify Galaxy Note has above 80% battery charge
  • Stock official firmware works only with Samsung Galaxy Note (GT-N7000). As flashing this on an incorrect variant is likely to brick device, verify model number of Galaxy device by navigating to Settings > About Device > Model Number

Note: Check if the Custom Binary Download is Yes, then proceed further. If it says 1 count or something like that then reset binary counter/flash counter of the device by installing TriangleAway app, released by recognised XDA developer Chainfire.

To Unroot Samsung Galaxy Note GT-N7000 to Stock Official Firmware

Step-1: Download appropriate stock official firmware (according to region) for Samsung Galaxy Note to computer

Step-2: Extract downloaded zip to get a file with .tar. md5 extension with other files

Step-5: Run Odin3 v3.07.exe as Administrator

Note: If Added message does not come then try another USB port (the one located at the rear). If Odin still fails to recognise device then re-install USB drivers

Step-7: Select files extracted from stock firmware folder to install on phone

  • Click PDA and select file with .tar.md5 extension
  • Click Phone and select file with Modem in name
  • Click CSC and select file with CSC in name
  • Click PIT and select .pit file
  • Note: Ignore final three steps if such files are not found

Step-8: Configure Odin settings. Ensure Auto Reboot and F.Reset Time checkboxes are selected but uncheck Re-Partition option; select only when .pit file is being used

Step-9: When everything is set, hit Start in Odin. The installation should begin and will take a few minutes to complete

Step-10: Once installation is completed, the phone will restart. Following this a PASS message (against a green background) will appear in a box at extreme left of Odin's screen indicating a successful installation. Now unplug USB cable from phone to disconnect device from computer

Step-11: Once phone is ready, head to Settings > About Device > Status. If it says NORMAL, this means the device is unrooted. If it says MODIFIED, then do the following:

Step-12: Reboot phone into Recovery mode

Step-13: Perform a Factory Wipe and then select Wipe Cache Partition

Step-14: After the action is completed, return to themain recovery menu and select Reboot System Now

Step-15: Check Download mode again. If it says either 0 or No then the Note can be subject to warranty claims

Step-16: If the counter stays at 1, it means the device had a non-stock kernel. Now root the device, apply TriangleAway and then re-flash stock firmware. The counter should now be zero but the status might show modified. In that case, do a Factory Wipe and the phone should be back to stock firmware.

The Galaxy Note should now be unrooted and running on official firmware with binary counter set to zero.
