Incompatible/unsupported apps:
Many app developers do not support this device anymore. You have three options:
  1. Use previous versions of the app which were compatible with this device.
    (APKMirror.com hosts many previous versions of apps.)
  2. Try the incompatible app anyways. It may run under NEON emulation. Emulation is very slow. The ideal way is to use previous versions of the app which are compatible with this device.
  3. Contact the app developer and ask them to maintain support for Tegra 2 devices.

  1. Backup all data
  2. Install TWRP 3.0 or newer
  3. Wipe cache, dalvik cache, system, data

Got an error? Is something not working for you?

I cannot see what your problem is from here. Save and upload the system logs from your device so that I can see what happening on your device.

How to save system logs:
  1. Root the device.
  2. Install SysLog.
  3. Reboot the system.
  4. Reproduce the problem.
  5. Open Syslog app and save the Kernel Log and Main Log.
  6. Send me the log files stored in /sdcard/Syslog.
    Share the files on Dropbox or another similar site.
    Then PM me a link to the files. Please describe exactly what the issue is.

I don't have this device but it's more or less the same as the Galaxy Tab 10.1 which I do have.

Please send me logcat and kernel logs so we can verify that things are working properly.

Initial thoughts: WOW!!! Performance is great. Took quite some time to install then boot up but once it started it worked really well. Gonna root and try over clocking. Will post screenshots as well. A million thanks to you for this.

Overclocking hasn't been enabled yet but performance is good enough without it. For root to work you need to install the Phh Superuser app from the Play Store. Overall solid and stable. screenshots attached.
PS: screenshots via adb does not work but doing it physically on the device works fine.
