    I've tried quite a few ways to enter the stock recovery menu of my 7035, I cant seem to get into it.

    Does anyone know how to enter the menu? Or how to get ADB to connect to it.

    My device is stuck in a reboot cycle with the Coby screen.

    when i try to enter Fastboot (power + vol down) the pc's sees it as a storage device called VIMICRO SUPER DISK USB DEVICE in the device manager, and a drive called VDfu with 512mb/512mb free (the ram?)

    not much you can do in fastboot or recovery mode. you need to be able to adb and remove the stuff you add to system. you can erase data from fastboot wont help much.

    I understand but what are you going to do if you get there? Nothing cause you have stock recovery.

    3. Press and hold power, vol-, and back button together at the same time.

    4. Hold all 3 buttons down, continue to hold all 3 buttons down past the COBY screen.

    5. Android System Recovery screen will pop up.

    6. Release all 3 buttons.

    7. Use Vol- key to scroll down to "Wipe data/factory reset"

    8. Once "Wipe data/factory reset" is highlighted press the power button to make selection

    9. On "confirm wipe of all user data " screen use vol- to scroll down and select YES -- delete all user data.

    10. Press power button to make selection.

    11. User data will be wiped out, reboot system now will be highlighted.

    12. Press power button to make selection.

    13. Unit will reboot.

    Grab a paper clip and hit the reset button on the back for a few seconds, wait a few more, then try to power up. Worked for me when I got the tab stuck in dfu mode showing the vDFU partition.

    Also to avoid getting in the dfu mode, you need to hit power first and then when the screen lights up immediately hit the back and volume- buttons. If you hit them all at the same time when powering on you will get in the dfu mode.

    Vol+, back button and power together got me recovery. Folken, what method did you use to get gapps on the 7035? I have looked at several methods but non of them seem to be for that model. Were you able to put CWR on it as well?

    To get gapps on the tablet I followed Patroitswrath instructions titled "GAPPS on the tablet:"

    http://www.androidtablets.net/forum...-coby-generation-3-devices-12.html#post207066

    and added the xml file mentioned here

    http://www.androidtablets.net/forum...-coby-generation-3-devices-13.html#post207096

    <EDIT>
    There were two things I did do before the master reset which I did not think was very important but maybe it is why TreeFrog20012003 could be having the issues he is having.

    1.) I edited android.accounts.AccountAuthenticator.xml at /data/system/registered_services to include the line

    <service uid="10028" type="com.google" />

    (Note: that after a successful master reset and set up this line changed to <service uid="10001" type="com.google" /> so maybe that is the correct uid to use)

    2.) I did a normal reboot before the master reset and on reboot android said it was upgrading. So maybe before you reset do a reboot let it upgrade and then run fix_permissions.sh, reboot one more time, and then finally reset.

    </EDIT>

    right after adding these files things did not immediately work (due to the proper accountAuthenticators not being registered). I had to do the reset mentioned here

    http://www.androidtablets.net/forum...bricked-7035-how-get-recovery.html#post228724

    And then on reboot the tablet prompted for the proper set up to configure the play store etc.

    Of note android commander never did find my tablet. So I ended up copying all the files over into the sdcard folder and then copying them into /system/lib, /system/app, and /system/framework etc. as root and setting the permissions as needed. I also ran fix_permissions.sh as found here

    http://www.getyourdroidon.com/shiversftp/fix_permissions.sh


    before the reboot.

    Finally Chrome hard locks my tablet. So if you try to use Chrome you might want to have a paper clip handy to restart the device. Otherwise I have not seen any issues.
