I've started porting CyanogenMod 10 to the Galaxy Tab 7.7. Do not flash this unless you know how to backup your data and especially unless you know how to get back to stock. If you don't already know how to do this, you might want to familiarize yourself with the process now, while the developers try to stablize CM10. I don't have time to help people unbrick their devices, and will not take responsibility for any user bricking their device, you flash this at your own risk.

If you are a developer interested in helping out with the porting effort, please PM me.

Known Issues
  • CM10 is in a primitive state, many features are still missing or don't work
  • HDMI dongle doesn't work (won't be fixed anytime soon, if ever)
  • Wifi features: hidden ssids, 5.0Ghz networks, wifi direct, portable hotspot
  • GPS isn't working
  • I815: CDMA and LTE isn't enabled
  • I815: Autobrightness is broken
  • I815: no IR-Blaster support (almost no chance of this ever getting fixed)
Google apps can be found at
Flash from ClockworkMod Recovery, and make sure to wipe data/factory reset. No whining if it eats your homework.

Build Instructions
Setup a standard CyanogenMod 10 build environment (there are plenty of tutorials on the web already on how to do this). Then
  1. Add add the following entries to your local manifest
    <project path="device/samsung/XXX"
        remote="github" />
    <project path="device/samsung/smdk4210-tab"
        remote="github" />
    where you replace XXX with your device (i815, p6200, p6210, p6800, p6810, or t869).
  2. Make sure that your device is running the newest build of CyanogenMod 10.
  3. Make sure your device is plugged in and has debugging enabled.
  4. Run the extract-files script from your particular device tree.
  5. Run vendor/cm/get-prebuilts
  6. Your sources are now ready, to build run
    $ . build/       # this sets up the build environment
    $ lunch cm_XXX-userdebug    # this selects your device
    $ mka bacon                 # this builds CM

  • 10/04/2012
    • Wifi changes (hopefully improvement -- sleep should be more consistent, hidden networks should work)
    • Keyboard Dock support (thanks to technomancer)
    • Memory Leak fix and 57fps (used to be 30fps) (thanks to Espenfjo and Entropy512)
    • Triangle Away is back

    • Battery section of Settings reports "Charging (USB)" when the device is plugged into a computer
    • Device specific settings (the Advanced section in settings)
    • Dock audio out -- need to enable in the advanced section (hopefully this fixes it, I don't have a dock to test)
    • P6800: Sim toolkit
    • Probably more stuff I'm forgetting

    • Wifi mac addresses are fixed (i.e. they are the same as on stock now)

  • 08/15/2012

    • Wifi works, hopefully without issue
    • Wifi Direct disabled (wasn't working anyway)
    • Wifi tethering enabled (no clue if it works)

  • teamhacksung -- adding the necessary exynos4 and audio fixes to the CM tree

Great work on the rom, I love it. I can confirm A2DP is not working in CM10 but it was in your last CM9 update. Just an FYI Thanks again for the Rom

Any chance you'd consider a TVDPI version? (Like the Nexus 7; ro.sf.lcd_density=213 + onscreen buttons enabled) Even a flashable add-on to switch mode would be nice (think it requires framework changes). Also: nice work!

Just installed it. GSM/Data working... Gallery sync... WiFi not tested yet and I seldom use it... MTP on PC really slow...


Update: Notification drawer, cannot change the default toggle
