Tips, Tricks, Caveats
FEL mode
The Volume +/- buttons trigger FEL mode. Unfortunately, FEL mode via this method appears to be useless for dumping device info.
Adding a serial port (voids warranty)
Device disassembly
Unscrew 2 small screws on the button panel side. Using a plastic tool pop out the sides and pull off the cover.
Locating the UART
The test pad nearest to the right side of the SD slot is serial TX. Tx is multiplexed with pin mmc pin 0, so expect to see garbage when using an SD card.
Rx hasn't been found yet (Neither front nor back test pads nor uSD slot pins). Read-only console for now.
