Hi to all! this is my first topic in this forum but i'm following it from a long time.. I have 2 icatch x11 series dvr (4 and 8 channels) last night i've udated the firmware from 1.0.3b93 to 1.0.3b96.. in the 8 channel dvr I've disabled the Automatically Synchronize" function on the NTP server and everythings works, but in the second dvr (I was very tires) I've forgot it.. now my 4ch dvr stuck on the vendor boot logo from yesterday night.. I've tried to push the restart button inside the dvr and to replace the battery inside but it still not working.. any help to solve this problem thanks in advance, i'm really desperate..

unplugged everythig like hard drive (data and voltage) monitor and LAN but is still not working.. I have no other ideas to get it work... thanks for your interest!
