I tried to update f700BT but after update it won't start just pioneer logo on screen. I tied again but now in service mode i'll try to upgrade from sd with format it freezes to 100% reading data,  i waited half an hour but didn't go any where. After this i tried to start testmode 2.0 and 2.3 it started an after few seconds f700bt shutsdown, here is youtube video of it. http://www.youtube.com/watch?v=zBfxL98vMzU

Can you help me i'm desperate,  i'we been trying to fix diffrent kind of methods for hours and nothing won't work.

Before i made anything  i took backup files from orginal flashdrive and i would be even happy if i coluld put those back and f700 working again.
