I am making this post after doing some research on several other forums. Here is the most important information I could find to help users understand the differences. What branch am I running? If your device is still running the stock ROM go to Settings > About Tablet > Tapu UI Version. If the numbers there start with 1.1 then you are on the old 1.1 branch. If it starts with 1.2 then you are on the new 1.2 branch. Another easy way to tell is if you have a lockscreen on your device. If you do, you are running the 1.2 branch, if not, you have the 1.1 branch. What ROMs can I use? Most all sites now are requiring devs to put "1.1" or "1.2" in the title of the ROM thread so that users know what they can use. Once you know what branch you are on you can browse pretty much any site now and know what you can and can't use. I am on the 1.1 branch You can read this: http://www.androidtablets.net/forum...st-1-1-roms-viewsonic-g-tablet.html#post59527 for 1.1 based ROMs. These are not the only ones but it is a good collection of them. You can find more over and XDA. Even though 1.1 is "old", devs are still pumping out ROMs for it. I am on the 1.2 branch I do not have a thread for 1.2 based ROMs yet but I will get one up soon. Once it is made I will post the link here. Here are some of the popular ones I have heard of. Flashback Honeycomb Alpha 3.0 Honeycomb Android Illuminate for The Gtablet\Zpad T2 Bottle of Smoke Honeycomb Century Eyes Mountain Laurel Brilliant Corners Should I upgrade from 1.1 to 1.2? At the time of this writing it is a personal preference. Pretty much all G-Tablets being sold today are running the new kernel which is 1.2 based. Devs are now taking the 1.2 based ROMs and porting them for 1.1 users. The Bottle of Smoke ROM is a prime example of that. If you want to upgrade, please follow the steps here: http://www.androidtablets.net/forum...to-upgrade-1-1-1-2-based-roms.html#post105316 I hope this helps some of you to understand the differances between 1.1 and 1.2 based ROMs. More information will come as myself and other Mods find it.
