I just tried to install the Xposed Framework on my Xperia Tablet Z. The Tablet has a reboot error if the Bootloader is still locked but rooted and /system is mounted rw.
In your install.sh you first remount rw, then backup /system/bin/app_pr...
That shouldn't be a problem.
the CDMA file isn't strictly a failure...it has just been resolved in a different manner. Everything on your phone will function as usual.
What exactly is your problem in recovery? What is the problem installing it...
I just have to say many thanks for this effort. Openpdroid works like a charm on my i9100 CM10.1.
