Comment 4 for bug 1607684

Also, probably related, I just discovered through an irc conversation on
#ubuntu-touch (thanks Mister_Q) that using the bq flash tool (which I did to fix an unbootable
system) and selecting 'format and download' (which I also did), would have
deleted the imei partition.

Quite possible, seeing as the serial number displayed in the 'about' section
shows "0123456789ABCDEF".

Apparently it could also cause my other problem of the tablet not recognizing
or outputting to HDMI monitors via a micro-hdmi to hdmi cable.

Although... that doesn't explain why the wifi problem has been seen before, or
why there's plenty of other reports of the M10 not outputting to displays (at
least not reliably). - see
