Hello everyone,

Last week I received my brand new Teclast P90HD (A6K7) and flashed some custom ROMs with the RkDevelopTool (RileyROM 1.1, OMA Multiwindow, OmniROM). Everything worked fine until I wanted to flash another compatible ROM and the "Erase IDB" function failed. Now the tablet is not booting anymore. I think the Bootloader is broken. The tablet is neither recognized by my PC nor my laptop (“Unknown Device” in Device Manager due to Enumeration failure). I recorded a video of the issue and uploaded it to youku (please disregard the background noises, it's just my girlfriend talking to the cat):

Can anybody in this board help me?
