How to patch/update the Augen Gentouch78 Tablet PC

I recently acquired an Augen Gentouch78.

The model I got: NBA7800ATP
When I took it out of the box, it was basically unusable as the touch screen was way off, and the built in calibrator did not work. Also, I was unable to connect it to my google account (the gmail app wasn’t there), and the android market was also MIA. Fortunately, I found a patch and the instructions (which of course weren’t bundled together).

The patch (v3):
Edit [October 3, 2012]: The above link hasn’t worked in some time. These days your best bet is to google the file name.
The “official” instructions:

Better instructions:

  1. Connect your Augen Gentouch78 to your computer
  2. Download the patch.
  3. Extract the “os” folder onto C:\
  4. Open the “os” folder
  5. Double-Click “update.bat”
  6. Hold down the Back button on the device. The back button is the first button (in the top left) if you are looking at the back of the device.
  7. Using a paperclip (or similar object) press the reset button (while still holding down the back button).
  8. Keep holding the Back button until your computer either shows the Found New Hardware Wizard or the command window running update.bat starts showing something like “sending ‘recovery’ (5104 KB)… OKAY”
  9. Once the command window closes, the software will be fully updated, and the screen of your device will still be black. At this point you need to hit the reset button again (without holding down the Back button).
  10. When you restart it will ask you for your Google Account (or let you create one), and in general will be much better calibrated.

That’s it! You now have access to the Gmail App and the Android Marketplace. Also, you will be able to get the official Kindle app.

One other thing you might want to get is Adobe’s Flash Plugin for Android Eclair v2.1. Which you can get here:

To install:

  1. Extract the .apk file from the zip
  2. Put the .apk file onto a MicroSD card and insert it into your device
  3. Open the file explorer, and click on the .apk file
  4. The install dialogue will pop up and you should be good from there.

    1. First off, make sure you have power going to the device (i.e it is plugged into the wall). Then try using the paper-clip reset switch (mine made noise when I used it). Finally, try pressing the power button again.

      1. John,

        You seem to be knowledgeable. My Gentouch78 is stuck in the sleep mode. I’ve tried to reset with the paper clip and it flashes the start up page, and then goes back to sleep. Any suggestions? It stays in sleep until the battery runs down. I can’t even shut it off. None of the buttons work.


  1. Excellent!!! Thank you so much for this it was exactly what was required. You appear to have missed out a step in your instructions (extract the USB adapter and point to its location) but I am SO grateful for this how-to. Thanks very much!

  2. well i got everything installed but i cant download anything from the android market place everytime i try it says down load unsucsessful any ideas to get it to work?

    1. Off-hand, you might try downloading just one thing from the store and then not doing anything else until it has finished.

      To my recollection, there were a couple of items that I tried to download that didn’t work the first time.

  3. Will this work for version 2, and if not could someone please diect me to a location with instructions… Thanks

    1. If you are asking if this will work when upgrading from version 2 to version 3 of the firmware, I believe so, but I can’t test. If you are asking about something else, I suggest you clarify.

  4. hi, i do it.
    it is a middle-good tablet.

    now i would like to put windows mobile
    into my gentouch78 it is possible?


    can somebody help me?


  5. Will this work for the 2nd Generation Gentouch78? That one has accelerometer and a white power button (not black)

  6. 1st gen gentouch, ver 1 loaded, model NBA7800ATP
    i keep trying this without success. at step 7, it discovers my device every time, then what? let it load the drivers? cancel? what?
    regardless of what I try, update.bat just sits waiting for device, never finds anything or starts doing anything else.
    I’ve loaded ADB, everything seems to work in that regard. no problems or errors connecting device.
    Cant’ get this update to work. is there a way to load this from SD card?

    1. From what I recall (I got rid of my device), you need to hold down the Back button until either Found New Hardware pops up on your computer or the command window starts doing something. Then, let go of the Back button and let it do its thing.

      I do not know of any way to load this from an SD card.

  14. ok i finally got the augen to be recognized by win7 had to uninstall asus android drivers from dev mngr and reinstall usb microsft drivers from augen update…. did OS update/fastboot / fastboot flash sys… all sending and writing OKAY still when i reboot my GT78 it goes to boot screen and then the little penguin guy and thats where it stays for 2 hrs now rebooted several times

  15. The reason your Gentouch78 is stuck at the Tuz boot is because you flashed your system with the version 1 firmware. if your device have a white button and 3.5 mm jack then it is version 2. the only way to fix it is to have someone with the version 2 copy there boot recovery and system image and flash it to your version 2 gentouch with fastboot. now i have a bricked gentouch78 i got for really cheap and need the version 2 image files. anyone with these could you put up a download link all others iv found are down.

  16. Hi, it’s don’t work for me, the windows recognize it as adb device, but the bat file still saying: and nothing happens, if i press the reset button again, it’s boot as usual without any update, someone can help please?

  17. This may sound stupid but I’m attempting this fix on my friends old tablet To possibly make it usable however I don’t know which folder is the “is” folder or how to extract it to the c drive plz help
