VCMM recovery
Hi All,
Does anyone knows how to force this bloody VCMM (MTS5440) to recover? is doing some work restoring roofs.ubi.img.gpg, but then suddenly says " The connection between the PC and the VCI has been broken". Power supply is stable 12V via charging port, usb connection is not interrupted. 
Any idea?

I don't have a clue, but let me play more clever biggrin

I would resolder all critical soldering points and than retry recovery..

thanks, will do, but strange point is, that equipment is not moved at all, and always error comes up at the same moment. i even replaced sd card, as i thought that it may be a problem, but is not.

ok, tried 32 and 64bits - same behaviour. 
laptop with and without IDS - same
old / new sd card - same 
win 7 - same 
win 7 /compatibility mode with XP - same

which component you think need to be re-soldered/replaced? cheers.

RE: VCMM recovery
iMX6 or flash memory, both BGA soldered.
Strange is that the S/N is not shown...
