I have been trying to update to 4.0 since I got my tablet a few days ago. Everytime I try to flash the update it wipes the OS and fails when installing update, I am only able to flash android 2.3 . I've been looking for topics about my model, I have not been able to find anything. If there is anyone that had this issue and knows how to fix it I am willing to try anything, plz let me know. Thank you
