Ippo q8h

This cheap (40EUR) tablet is an A23 based update of the hugely popular Q88, which was based on the A13. It is currently often sold as an A13 device, even though the A23 is a serious step up from the measly A13. = Identification = The Q8H has multiple revisions, with minor variations to passive component placement.

= Tips, Tricks, Caveats =

Android ADB access
Standard ADB does not work out of the box. You need to provide a config file containing the usb vendor id:

mkdir ~/.android/ echo "0x1F3A" > ~/.android/adb_usb.ini

Opening the device
As is the case with the Q88, it is absolutely trivial to open this device. Just apply a tiny bit of pressure with a fingernail on the outer rim, and you will soon hear the clips popping.

= Adding a serial port =

An obvious serial port is available on the mainboard, to the right of the SoC, but this sadly does not produce any output under the stock android image and has not been verified yet.

This hardware is sold under many guises. If it is claimed to be an A13 tablet but with a 4.2.2 android, then chances are that it is an A23 one instead.
