I just wondering If I can downgrade my firmware from 4.4.2 to 4.2.2 or 4.3 in safe way
because I read that is not safe to downgrade because ,,, you may lose your network access & IMEI & and get invalid SIM !!!
How I can avoid that ???
because I have a big problem I cannot solve it at anyway I try many rom's (stock rom's & customs rom's like(cm11 )
and the problem not solve it !!!!!
the problem is / I cannot record video (camera video mode) ,,, when I do that the mobile freezing the restart !!! also youtube videos not work !!
and If I play video any video on mobile is freezing and stop working !!!
SO I would like to downgrade my firmware maybe will solve this problem
or I will wait your help for another way to solve this issue
