Manual build specifics
TBD

sunxi-boards and u-boot forks with info gathered so far on github.

FEL mode
It has volume +- buttons and power button. Maybe one does trigger something. Manual does not say how to trigger FEL mode. The (polish) post here suggests that VOL buttons should trigger FEL mode http://www.manta.info.pl/forum/mid705-firmware/mid705-android-4-2-2-3738/ There is an interesting jumper position labaled u-boot near batter and another one near wifi.

= Adding a serial port (voids warranty) =

no useful way to add uart found so far

Device disassembly
It has screws next to the connectors. Cannot be disassembled with a SD card in the SD slot. The board is on the display part and the bottom cover is removed. Remove the screws and pry the bottom cover. Make sure the USB port is inserted into the cover first when reassembling.

Locating the UART
UART is marked on the bottom of the PCB (between the PCB and display) and on the top under the tape holding ctp connector. Both connect to the SD slot so you can as well use a SD breakout board. The FEX file does not enable UART. UART howto.
