Maybe the cause is that CM 10.1 is not supported by this kernel... see OP.I am trying to get dual boot work for some time now...
What I do:
I Clean to Install a new ROM
Then install the kernel and then the multi boot package
Then I install cm10.1.3 and then cm11 latest nightly
When I reboot everything seems to work good.. Then I go to aSwitch and I choose to restart to 2nd ROM, but then on the restart I keep getting a black screen after the logo(and when I press several times the menu button it turns white )
Do you know what the issue is?? I have a GS3 gt-i9300
