New Guide for Rooting the ViewSonic G-Tablet


Outdated Article!

This entire series of articles is deprecated! See the list of “gTab Outdated” files at the bottom of this article.

Newer ROMs and advanced procedures have replaced (or made obsolete) the information in these articles. This article is retained only for archival purposes.

The process of  “rooting” in not required on the ViewSonic G-Tablet. Just begin with our “NVFlash for Dummies” article which REPLACES these instructions.

Release the power of the GTab!




For most users – If you wish to install a bl1.2-based ROM such as Honeycomb, then visit HoneyComb on GTab! and do NOT use this guide!

Although this article is still valid, it assumes that you will be flashing a custom ROM based on the 1.1 bootloader. That is NOT the recommended version at this time. I HIGHLY RECOMMEND that you begin with the 1.2 bootloader and associated ROMs.[/warning]


(These instructions replace the previous article which was available here.)


Continue with this guide if you wish to install a 1.1 bootloader.


This simple “How-To” guide should enable most people to root the Viewsonic G-Tablet and install a custom ROM in less than an hour. Doing so will make the GTab operate as well as (or better than) almost any tablet on the market (eg, iPad or Xoom).

Here is a video of what the (rooted) GTab can do:

[important]Much of the data for this guide is available on the XDA Developer’s Forums. I appreciate and respect their work – and none of this would be possible without them. To understand why I have posted here (rather than on XDA) see my article on the subject: http://bishoptec.com/2011/04/xda-developers/[/important]


There are several sections to this guide:

(Check the right sidebar or the area just below this post for a complete list of related articles)

  1. Introduction (this article)
  2. Check Bootloader Version (here)
  3. If you wish to install a bl1.2-based ROM such as Honeycomb, then visit HoneyComb on GTab! – otherwise, skip this step
  4. Installing ClockworkMod Recovery (here)
  5. Flashing a Custom Rom (here)
  6. When Things Go Wrong (here)
  7. Tips and Tweaks for Android Users (here)

[important]Normally, these steps should be followed in the listed order. However, once you have finished “Installing ClockworkMod Recovery” (CMR), the CMR image should remain and, for future flashes, you can skip directly to “Flash a Custom Rom.” Hopefully, you will never need “When Things Go Wrong” but it does offer some additional helps and suggestions for issues or questions that our users have presented (kind of like a FAQ).[/important]




WARNING: Installing ClockworkMod Recovery and a Custom ROM will void the warranty on your Viewsonic G-Tablet! 

Also, any data or installed apps will be deleted. However, any apps that you previously purchased will still be available under your account so you should be able to reinstall them without additional payment.

As with all such guides on this site, this “How To” is presented as a help. Any modifications that you make to your device are done entirely at your own risk. [/warning]

[notice]NOTICE: DO NOT install a MicroSD card in the GTab’s slot (under the rubber cap on the left side, near pwr button). If a MicroSD card is installed, push it into the device and it will spring back out and can be removed. Although this is not absolutely necessary, it will REDUCE the level of confusion about the internal and external SD Cards. After finishing the steps in this process, you likely will want to add an external micro SDCard to the GTab.[/notice]

[warning]If you understand (and accept) the possible problems related with this process, read on to find out what you must do in order to release the power of your GTab![/warning]
