Eken_MID7_W70_GSL1680_Z7Z67-030A Bricked

Hello everyone I'm new here and a noobie when it comes to Android tablets and phones. any help is much appreciated.
Has anyone had 1 of these tablets. Eken_MID7_W70_GSL1680_Z7Z67-030A. Its a cheap chinese clone and has another name of Wondermedia WM 8850 7". I have had this tablet for just over a year and for the last couple of months its not been working. I have had a couple of friends who are clued up with computers have a look at this tablet but neither have been able to get it working. They have tried Uberoid I think. Any info is appreciated. But it looks like its for the bin

I'm still trying to get this tablet fixed, has no one heard of this make? any info is much appreciated.
