If you are new to betas and want to "roll back" ensure you have Odin3 v3.14.1_3B_PatcheD and Frija v.1.4.4 installed on your PC and download the latest firmware. This will allow you to leave the beta and restore your phone.
No, use the user csc which keeps all of your data. The Home csc wipes everything and factory resets the device. Make sure that when you use Odin you untick auto reboot. To reboot device, hold vol down and power till device reboots.
