PainBreak, you've done some good work on this and great job for starting the 4.0.4 thread.
The 4.0.4 unit is showing a LOT more potential than the older 2.3 unit.
I'm currently working on an update.zip with all of the little changes needed included into it.
I feel we could get a lot more out of this than the 2.3 system. One thing we are all looking to I'm sure, is getting Bluetooth running on the android side.
I have an android compatible BT dongle here which we have tried to use, but the switch in settings will not turn on,cleaning me to believe Bluetooth.apk on the system is deactivated or missing. now the units are rooted, im sure we can resolve this somehow.
I also have a fix if anyone gets stuck in a boot loop, to force update, but it needs the unit to be opened and I don't think it would be a good idea to put it in the public domain just yet, as people will likely brick their systems and blame me.
I have shared this with painbreak, as it gives us an added level of security in case of screwing up as you can just force an update.zip even if not booting.
