Unisurf USFT60U7BLK

This exact model may have been available only in Australia. However, the Printed Circuit Board (PCB) includes a "INET-D71B" designation (visible only after after disassembly (below)). It may be possible that the information on this page is applicable for other INet D71 devices as for the similar Inet_D70_A33.

There are no obvious UART connections on the mainboard.

Device disassembly
There are 24 plastic pins to pop around the perimeter of the back cover. A plastic tool is recommended. The most difficult segments to pop are the bottom right and bottom left corners, because they have pins in the middle of the curve. This also makes it particularly difficult to pop the right short side (the side with the mic port), and the left short side near the USB port. A suggested approach would be to pop as much as possible all around (including these difficult segments), then lever off the cover along one of the long edges.

Note also that the power and volume button moulding is a small, loose part that can fall out in the process.
