Problems installing custom ROM on LG 2x

Hello all,

I want to test my B4A code on a real 4.2.2 device. I have a spare LG 2x p990, which I managed to install CWM on and have a rooted stock 4.0.4 rom now. But when I try to install CM10.1 from a zip file using CWM 6 it just re-installs the unrooted stock rom. What's going on???

Nevermind, problem solved. I installed the original 2.3.3 stock rom, then rooted using AIO toolkit, then installed CM10.1 as this expects 2.3.3 to be installed, not 4.0.3. I'm now running Android 4.2.2 which runs great. (Although not as great as 4.1 on my Galaxy S2)
