after my chinese phone (mentioned in other thread) died, I deceide buy a good phone. But this has the random reboot problem (I found about this problem in other devices) and the more efective solution seems a system update or install cyanogen
but samsung has no release any update ( only a brazilian version....) and I cant found a (safe &comprobed) way to install cwm or another recovery and cyanogen (or another rom) in this model
have a nice day
pd. is already rooted
edit: if i backup the recovery with Razr app, could I restore it without risk?
