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Outdated Article!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 See the list of “gTab Outdated” files at the bottom of this article.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.

Please check out our NEWER series of articles on the ViewSonic G-Tablet:


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.

RootedThis 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:[/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]



Neither Ray Waldo nor the site/domain (or any of the sites linked here) will be responsible for any damage that may be done as a result of following the instructions in this (or any other) guide.

Neither Ray Waldo nor this website has any affiliation to any of the sites linked in this series of articles.[/important]


[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]

    so curiosity enraptures me. What pray tell happened to your gtab?

    Does Honeycomb allow overclocking now or is ICS the way to go and does that allow overclocking?

    Will flash work on ICS and do you have a link to get me there?

    You also suggested NVFLASH for dummies even before CwM, do I still need to do that first?

    All of the pre-installed apps on its desktop will go away including my market app? How do I get my market back? I finally figured out how to use Amazon app Market.

    Dang, so many questions…..

    so Ray, it appears I will need to use a bit 1.2 based ROM but I have a few questions. Your guide on the Honeycomb seems to indicate it cannot be overclocked and that was one of the sweetnesses I wanted for my gtab – YES I realize it will drain the battery faster – so which of the ROM’s would you recommend and why. also it has been some months since you published these articles. Are you still happy with your modifications? I want to try to use my gtab at work for some flash-intensive work. You also indicated at one time that I use Clockworkmod first. Does that still hold true and does that “SAVE” my apps and data? Is there a walkthrough for learning droid system controls somewhere? will I be able to re-install my existing apps without having to pay for them again?

    thanks in advance,

      Almost any ROM can be overclocked with an APP from the market. See the notes about the specific rom.
      My GTab is broken (hoping to get another any day now). I have not tried the ICS ROM but it looks good. Honeycomb is great but I think they have stopped developing (in favor of ICS).
      CWM is essential in order to flash new roms. Just follow the instructions in the link at the top of this article. CWM will also do a full backup/restore.
      The Android settings are pretty self-explanatory. Just visit each one and make any desired changes (the defaults are usually the best.) Do ONE change at a time and if it causes problems, just switch it back.
      I don’t know where you purchased your apps so I do not know their polices. Apps purchased from the Android Market or the Amazon AppStore are still valid if you sign in with the same email account. However, some apps will not work across major version changes of Android. Froyo apps may not work on Honeycomb. Honeycomb apps may not work on ICS. ICS apps may not work on earlier versions.
      All of this is covered in the other articles on this site. Please read each article as they are suggested (from the first link above).
