We have featured ClockworkMod recovery on numerous occasions before.

  1. Backup any data from your device that you may need later.
  2. Download ClockworkMod recovery from the link given below.
  3. Extract the contents of the downloaded file to your computer and copy the ‘recovery’ folder as well as the ‘update.zip’ file to the INTERNAL memory of your tablet.
  4. Turn your tablet off and reboot it into stock recovery by pressing the ‘Power’ button while keeping the ‘Volume Up’ button pressed.
  5. Navigate to ‘apply update.zip using the volume buttons and press the ‘Home’ button.
  6. Wait patiently while ClockworkMod recovery is installed to your tablet. This will also automatically root your tablet.
  7. Reboot into Android from recovery.

That’s it – you now have ClockworkMod recovery installed on your ViewSonic G Tablet and your device has been rooted as well. Why stop just at the recovery?

    • Yo mismo-I got all the way to the point that we run nvflash_gtablet.bat and command.exe comes up and says:

      Nvflash started
      nvflash configuration file error: file not found
      Press enter to continue

      Any suggestions?

  4. got it…install cwm via nvflash…then flash the rom…be sure to partition the sdcard 2.0/0 and clear cache and userdata…working great now.

    • Can you give a bit more details? I get this issue too and can’t really follow what you posted.

  5. I put the recovery and update.zip file onto the root of my internal sdcard and booted into the stock recovery. Now when I try to boot into recovery it just sits on the viewsonic screen with recovery key detected and Booting recovery kernel image in the top left corner of the screen but never boots into clockworkmod recovery. (It does boot into the stock tap n tap ui that I did not flash a new rom for yet because clockworkmod is not working and all my apps and the software seems to be working fine.)

    If I go to the recovery log using root explorer on the internal sdcard, it shows the activity for today and it says:

    I:Got arguments from SDCARD:recovery/comand
    Command: “//sbin/recovery” “–update_package=SDCARD:/update.zip

    Any help to either get clockworkmod recovery working or stock recovery without doing NVflash?

    • Same exact thing for me, verbatim, as Graham.

      I’ve deleted all of the files (recovery folder and the update.zip) from the gtablet and copied the cyanogen zip file from the internet over to the gtablet and extracted it with ES Explorer and copied it to the appropriate structure as a last step and it still didn’t work. This was after downloading the cyanogen file for a second time to make sure it wasn’t corrupted.

      I got into the stock recovery only on the very first time earlier tonight (just like Graham) and it crashed or just seemed to not load (just live Graham, but I dunno how long I actually waited… it was at least 20 mins) and since then it has been just booting to the key detected screen and stalling when I hold down the volume+ key and power (just like Graham)… or if I just let it boot it boots up to the stock version just fine.

      Dang, any ideas out there? Are these latest versions shipped with some very recent firmware change that doesn’t like this “rooting” technique and we are just the first few to find this out? What gives? 8)

  6. Need help BIG Time, After running the clockwork mod zipfile as explained…. I rebooted it and it will not boot up it keeps turning on and off. What can I do?
