where can i found the non custom rom ,thats comes with the cube when first brought

 

got problems with it and its going to be sent back for repair .but would like it back to factory default rom

 

cant seem to find this anywhere

Look through the threads of this forum pages. Its there. look in the ones that have a rom specifically. You will see mention of that rom. Or you can go to geekbuying .com, write U30gt2 in the search window and it will take you to a page with all the official firmwares.
