Security Error LG P768E
Hi people! After couple days of trying i decided to make a new thread. I got a cell phone from my friend with ''Security Error''. I searched for solution almost whole forum and tried all guides but with no success. When i plug USB cable PC connect and then disconnect link and show ''Security Error''. In s/w upgrade mode PC detect phone but when i try flashing lost connection. In offline mode installation stuck at 4%. I tried couple versions of drivers including newest one. In online mode of flashing installation stuck at 30% in LG PC Suite and wont start online mode of installation. I tried couple of computers and USB cables.
I'm begging someone try to help me, i'm going crazy!
Sorry for my bad English!
