[Android Head-Units] Tuatara:
This is a very interesting issue. If reinstalling the MCU fixed the "muting" issue, then there is something in the MCU configuration space which is causing the mute to occur. I doubt that the MCU would be writing to it's own flash memory, but there may be some persistent storage (battery/capacitor backed RAM in the Real-time clock, or an E2PROM) which is causing the fault. By reflashing the MCU, these values are either cleared, or reset to defaults on the first boot, and everything works properly again.

I'll add this to my 'to look into' list, to see what I can figure out. For now, reflashing the MCU is a viable solution, and probably should be added to the Wiki. There would be no issues flashing the MCU occasionally, but you wouldn't want to do it every day/all the time.

Great to hear about happiness and success!

With a proper supply, you should have no power issues on the host port for the 3G stick. The fact that it comes up, says that the configuration is correct, and it's able to bring up the connection. The fact that the cellular data disappears would indicate to me an issue with the sim card and/or the pin code you're using. I just tried my dongle with a 'dead' sim - one which can still make emergency calls on the network, but has no phone or data plan connected to it. The modem did exactly the same things as you described. It would find the carrier/network, attempt to connect data, and then fail and remove the connection (unauthorized). I would try the 3G stick in your computer/PC, where you can check the connection and ensure that it works. If it works there, then it should work on the android box.

Try opening Chrome, and going to http://www.useragentstring.com/

This should display the "pre-programmed" string I put in the ROM, specifying a Nexus 7. If it doesn't please let me know ... if it does - then all should be good.

I believe that the Play Store app uses Chrome when it is available and installed, but it's possible that it doesn't. Try to use Chrome instead, and go to the Play Store directly through there, without using the Play Store app itself. Are the apps now visible to you?

As for the App itself, I don't know why it's not detecting android 4.4.2. That may be a bug with the app. Can you provide me with the exact app you're trying (Private Message fine), and I'll try installing it and see if I encounter issues I can resolve.

The animation itself needs to be specified to loop in the "desc.txt" file contained in the animation. If this file is not correct (and I'm not familiar with the format), then the animation will not run as expected. Check to make sure this is correct in the animation you're using.

Xposed Framework should be installable. I don't believe I could have done anything in the ROM to prevent this. Can anyone else chime in with their experience with Xposed?

Otherwise, please send me (PM) a link the version you're attempting to install, and I'll give it a go as well.

I'm hoping that someone will be able to do this soon. (usafle? can you do a Viper write up in the Wiki with all your research - incl. bluetooth support?)

NOTE: I will be building a 1.1.4.3 ROM sometime soon. This ROM will have the ViPER4Android APK moved from /system/app, to /system/preinstall, because there are known issues with updating ViPER if it is a system app. There may be a fix or two I can implement, but we'll see how it goes. Additionally I will be using updated build.prop settings (which I've been testing, and believe to be better), along with custom build.prop examples for timezone, date format, 1GB/2GB models, soft buttons enable/disable, and anything else deemed important - for everyone to use, and customize their ROM using the Firmware Tools.

Thanks! That's good feedback, even when you have very little to say about anything going wrong. I also have a 2Gb unit, which is what I've been building and testing on - so I've also found it very stable.

Is there anyone with a 1Gb unit with any comments/info/issues?

Also - is everyone happy with the ClockworkMod settings? Is the touch-screen working for you? Is keyboard/mouse control workign too? Are the backups and restore operations all working? Again - let me know if you experience any failures.

Cheers!
