[mahabad1972]

hi i have a Hi718 Android TV Box Rockchip RK3188, i downloaded and install this firmware first Geekbuying_TV BOX_RK3188T_Android 4.4_official_AP6210, everything was smooth and fast but no wifi or ethernet working so i flash it with k-r42-wasser-kikat-0.91, ethernet again not working but wifi works, so i thought give it another try and install kitkat 4.4 Geekbuying_rk3188_4.4.2_box_q7_v001_beta_20140409, but not when i flashed it everything goes fine with no error but when i connected to tv it won't show up on tv does not detect hdmi cable any advice please,,,

Mine never works through hdmi because my tv has 1366x768 resolution
My problem now is continous rebooting... How can i factory reset it without a completely boot?
Where can i find step by step how to Update firmware or flash it? And the archives.
Can you help me?
Thank you
