I'll try and answer some of your questions as soon as I get to a computer.
Sent from my space time Continuum using the XDA App.
1. I'm not a dev, but here is what I understand about kernels. A kernel is part of android that contains the "drivers". You can use different kernels with the same ROM, but if you're asking if you can use 2 kernels at the same time with 1 ROM, then no, you can't. Kernels are usually flashed with clockwork, but we continuum users also use ODIN because of the difficulties with CWM not wanting to work on some phones.
2. Are uoi using the menu button to select in CWM? If you are, try clicking the lock button instead.
3. I can't help you there, sorry. :-/ My CWM always worked...
4.I'll see if I can't find a guide or 2. I'll make another video tut if needed.
5. There is a stock ODIN file that I helped make floating around here somewhere. The only thing is, the ODIN is rooted because it was needed to create the files.
I'll answer more questions later :P
