The line that produces factory image was accidentally left by me while
testing before inital commit, d13b05741a4d05a271d26fc3be61e76530025098
I came to the conclusion that flashing from OEM firmware does not work
(seems to share this behavior with other tplinks based on mt7628).
I have not done any further analysis, as I was unable to open the
case and attach a serial port (too much glue). Maybe i will try once
more.

So the way to do initial flashing (or un-bricking) is to use the
tftp-recover image. It is possible to revert to OEM firmware with tftp
recovery; in this case the first 512 bytes the image file need to be
cut off.
