The answer is maybe. What you describe is an old tablet design which was built/designed over 18 months ago. There may be community firmware, but what you describe is similar to lots of unique tablets of that period. Choose the wrong one (CFW) and you have bricked your tablet. I must warn you, if you are expecting vast improvements, you may also be disappointed. Search against your WMT2.1.2_105 and Firmware on the forum. You may find one that is compatible.
