aliasbody, the problems you are listing arent bugs in australian fw. {i used it for 6mos}. in fact, they may be hardware problems, in which case youre just effed.

still, flash the firmware and see if it helps! click the link rzr provided and read all about it.
here is the lowest-numbered firmware you can flash:
http://skeiron.org/firmware/N9/40.20...%2016GB.tar.gz

{i recommend that you also flash your emmc at the same time. if you do, you CAN use the 001 version, and it has less crap in it.}
{i also flash the openkernel; if you do, remember to wipe the disclaimer-cal BEFORE you flash it.}

here is the 001 emmc {and firmware, but you cant use the fw}:
