THIS IS DONE AT YOUR OWN DESCRETION and I am not responsible if something goes wrong or you do something wrong. I have repeated the process at least 10 times to see how it works. Even did it on a Samsung Galaxy S4 and Note 4 with no issues.
PLEASE TAKE YOUR TIME even watch the video a few times before you give it a try. In the end you can always flash stock Samsung Rom and do a factory reset.
I really enjoy using this feature and having the choice between two different roms on the same phone.
You can share apps from your stock Samsung Rom to your Cyanogenmod Rom without having to reinstall most of your apps. Saving lots of space.
I hope you enjoy.
Click an add or two.
Thanks and a wonderful day.
Happy dual booting.
