If you’ve ever heard anyone ask why install a custom ROM on an Android operating system, there is a good answer for ViewSonic G tablet owners: to update the firmware. Upgrading or updating official firmware builds is no longer an option after your phone or tablet carrier networks refuse to contentiously update forever. Eventually these OTA’s stop rolling out and you are forced to rely on installing a custom ROM or update the device completely and buy something newer.

These are the best custom ROMs available to install on the Viewsonic G tablet so you can upgrade your firmware and run newer versions of Android on the tablet:

Note: Make sure you check what model number the custom ROM is made for from the download links. Whenever we create a post such as this one, it means the model numbers are all thrown into the same article. Don’t assume that all custom ROMs will work for all model numbers. Each download link will mention what model number the ROM is for somewhere on the page, either in the custom ROM thread title or the original post closer to the download link. If you still don’t see it there then have a read of some comments or leave a comment yourself if you aren’t sure, and the custom ROM poster or other people subscribed to the thread will help you out.
