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.
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.

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

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.
