I botched a wire directly from the ground pin on the chip instead. I managed to lift the GND pad on the adapter by barely touching it with the soldering iron, so be careful here. Align it up, solder the two pins to the adapter board, fill up the three holes with solder and lastly connect a wire from the ground pad of the adapter to ground on the main board. Basically, you first desolder and lift the 6th and 7th pins (from the right) of the ribbon cable connector and then place the chip under the two lifted pins. The bivert module from Handheld Legend is a 74HC04D Hex Inverter (SO14 SMD package) mounted on a small adapter board. This will initially invert the pixels, but then you rotate the polarizing film 90° which inverts them back again, resulting in an overall better contrast. To make full use of the RGB backlight, you'll want to install a "bivert" chip.
