Skybox F5s SkyBox / Libertview Box won't turn on

[lehart]

Hi i updated a friends channel list using AJSATs channels and a USB... Since then the box won't turn on, all i have is a dim power LED and dim 8 on the dispaly - I've tried using Null Cable but it fails to get past syncronising STBs it just stays on that forever. Any advice would be greatful

The box is a libertview box F5s
