HELP! lng pack causes problems

Sep 7, 2012
I flashed the lng pack 2.8.31 on the on the 2.9.7 rom version and some problems were caused: the keys (home, vol...) don't work anymore. with 2.8.31 rom version it's works good. I'm new in it, so sorry for the Q guys. should I wait for new updated lng pack? or it's some problem with the device? thanks!
