Side buttons
With the board powered off, hold Volume+ (HOME button on the key-panel), then hold the power button for about 2 seconds, release it and press at least 3 times immediately.

UBOOT button
There is an unpopulated UBOOT switch/button connector. You can either short the pads and power the board on, or solder a switch/button and turn/press it before powering the board on.

NAND storage upgrade (voids warranty)
Some INET-3FTD boards have an unused NAND chip slot which you can use to upgrade the board's storage capacity. There are two known supported NAND chips:
 * Micron 29F32G08CBACA
 * Hynix H27UCG8T2ATR

These are SMD components, so standard SMD soldering advices apply.

Power supply
This board supports independent 5V charging with a barrel-shaped plug connector.

Reset button
This board can be rebooted with a single press of an on-board RESET button.

Device disassembly
Unscrew the two screws located on the bottom port panel. Use your plastic tool to pry-open the device's cover - it is advised to start with one of the corners to minimize the risk of damaging the LCD screen while opening the device.

Locating the UART
UART connector pads are visible on the board front pictures. They are clearly silk-screened on the PCB, but hidden under the touch digitizer flex cable. Unplug the flex cable to gain access to the pads. Cables can be soldered according to our UART howto.
