[LG Optimus 2x] bihariel:
This is a leaked ( Anonymous source) debug version of ICS for p990, it is outdated ( 24-04-2012) so there are some bugs. It is only for testing propose and for the devs to paly with it. I don´t have this phone more, i did the testing on my brother´s O2x, so i can´t make more things for this ROM.

Be careful, this is only for DEVs and users who want to try it. I am not responsible of any damage on your phone.

Please keep this thread clean for devs, for off-topic and users discussion go to the thread created HERE for you.
