There being some renewed interest in these units, I have reposted my method of upgrading the Geniatech Enjoy ATV 1000 Android TV Box and its re-badged, NeoniQ, GTV 220 and MyGica ATV1000 boxes to an ICS version. It will probably work on the ATV2000 as, I recall, was an ATV1000 with a High Definition DTV-T USB dongle and associated DTV app.
I have uploaded all the firmware to cloud storage.
Currently my unit is:
Model No.: M1 Media Box Board
Android Version: 4.0.3
Uboot Version: V1.3.6-25-g003d73d-dirty(20120719.18033)
Recovery Version: V1.3.0-87-ge46e804-dirty(20120605.160540)
Kernel Version: 2.6.34 Sat Aug 4 10:20:49
HKT2012
Build No.: 20120730
Note: The Serial No. of my unit is M3V2240000512
The M3 is misleading as it has a M1 board (see above)
V224 means that it originally was Android Version 2.2.4
0000 means ????
512 means that it has 512MB of memory
I have uploaded the instructions as a word document to:
