Viewsonic GTab stock firmware is quite buggy and slow for such a powerful and feature rich device. This has forced the tech enthusiasts using this device to turn to custom ROMs with much better user interface and speed boost over the stock firmware. One of the most popular custom ROM for this device is the TnT Lite firmware and now, there is good news for GTab owners as another custom ROM is now available for the GTab by the name of GAdam. This ROM is based on the Notion Ink Adam tablet firmware that has already been ported to a number of other Tablets as well.
This ROM features several enhancements over the stock ROM including Flash player, Google Apps, Youtube app, Home Switcher app, Live Wallpapers and Ad hoc networking. Furthermore, several performance and usability tweaks have also been added.
This firmware is still in alpha stage and will also flash your device’s kernel/system so you must be careful and know what you are doing. You will also have to wipe your data after you flash this ROM, so ClockworkMod is required. The following video demonstrates this ROM running on a Viewsonic G Tablet.
In case you don’t have ClockworkMod Recovery already installed, download it from the link given below and install it to your device using our guide on how to install a custom recovery to an Android device.
