Hello 2 days ago Kyros MID7010-4G Coby tablet bought from DUBAI. I opened for the first time. Wireless has made an error and closed. I opened again. Wireless does not scan. I did reset. I restored the factory settings. Wireless does not work. Now I went back to my country. I can not change the market in dubai is received. How do I resolve the error. Is there a software update. Waiting for your help.
