So I'm stuck on build one of the android 10 beta. I left the beta testing shortly after it started due to issues, and now my note will not update or do anything related to that. Just stuck on beta. Anyone know how to fix this? Thanks
You May need to factory reset your Note 10+ altogether.
Hold Down the Volume up Botton, The Bixby Button together which will take you to the Bootloader>Hold the Bixby Button then Press the Volume up button>This will take you to the bootloader where you can clear the Cache and factory reset your phone. Hope this helps.
Have you tried using Smart Switch on a PC? You may be able to download the latest software update that way.
I would recommend going to a local UBREAKIFIX and have the software reflashed. Before going I would recommend backing up your device to save your data. You can look up a location by using the link below.
