Purchased an M2 marked as defunct and it came as defunct! Surprise!

Press ON/OFF and after very short time green LED begins to blink fast. And doesn't stop (tested for several minutes). Pressing ON/OFF again will stop it.
Pressing Play button at startup does *not* startup camera. But opening battery compartment, pressing Play (and keeping it pressed) and closing compartment door will startup cam with blinking LED. Can be shutdown by pressing ON/OFF, too.
If procedure is repeated without battery pull cam will not startup.

I tried with/without card. I tried cards prepared for ML. With/without Portable Display Test autoexec.bin and with cards prepared for other cam types. No reaction so I assume cam's bootflag is not set.

I suppose there may be a slight chance to get some diagnostics by accessing cam's UART and that's all I can do. Right?

Got mail from connector distributor: Delivery estimated in 3 weeks.
Web site says 10 weeks.

EDIT:
I have an micro-SD adapter able to provoke the same LED blinking with my EOS M. If inserted into 650D cam will just not start.
This adapter once got some rubber/leather glue attached to contact pads and hasn't got a proper cleaning.

Could it be? Just a mere contact problem? Sounds too easy!
... and probably is. Error exists without card inserted ... sigh!
