[Q] Restore after flashing JB - issues

[alecxm]

This is my phone:
Model: Samsung Galaxy SII GT-I9100
Android Version: 4.0.3
Baseband Version: I9100XXLPS
Kernel Version: 3.0.15-I9100XWLP7-CL340913
[email protected] #3
Build number: IML74K.XWLP7

I've successfully flashed the "leaked" JB 4.1.2 ROM on my SGSII, just to see if I could do it - and then restored it back to ICS 4.0.3, with all my apps and data intact, using CWM recovery. While I had JB installed, I found that I couldn’t enable USB debugging, which made me nervous, as I know that a number of the utilities I’ve been using require it.

So my questions are these:
1. any ideas why USB debugging wouldn’t switch on, and what could be done about this?
2. if I were to do the JB thing again and keep it this time, could I use the same rooting mechanism that worked on ICS, and get all the apps and data restored - but this time running under JB? The package I used went by the name CF-Root-SGS2_XX_XEO_LPQ-v5.3-CWM5 – it includes CWM Recovery.
3. or if not, what is the best way to restore apps and data in this scenario? I really, really don't want to have to restore all my apps and data one by one when I upgrade my phone.

Of course I could just sit on my hands and wait until the official release.... Where’s the fun in that?

Might get a better answer in the Samsung Galaxy SII GT-I9100 forums.
