Before you open the link, I just want to say that this ROM was uploaded by t-shock on XDA forum. Therefore I don't deserve any credit for this. I merely made a short and quick tutorial on how to safely update your Note 10+ to UK One UI 3.0 Beta without a PC.
*This method only works for model number - SM-N975F and you should be updated to November update with last 4 characters of DTJ4. You can see the video for better step by step installation.
DISCLAIMER: Samsung and I are not responsible for any damage or data loss that may occur on your phone. Therefore it is best to back up your device and not to install it if it is your primary device or if you are using it for work. I have shared this info for those who are interested in trying out the One UI 3 Beta on Galaxy Note 10+ on their own risk.
IMPORTANT: Recovery mode doesn't work with Volume Up + Power. You will need PC to turn it in recovery mode using ADB Shell.
