I rooted the CM when the forum topic about rooting was made. All went well but after a while my phone kept powering off . I thought this was a problem with the root/software but it seems it persisted after i upgraded to JB. After i made the JB update, no "power offs" but after i rooted the phone the problem persisted so i thought i should Perma unroot it. Did that but seems the problem persisted. It seems it has something to do with the internet connection or my SIM card. I don't know exactly what is the problem so i am asking if someone has a simmilar problem.
PS. I have to add that after i perma unrooted the CM i did a WIPE. And the "power off" problem hits when i activate my Wireless or my Mobile network connection.
