Hello... I bought an unlocked Chinese Android phone (A8000). The phone worked great, until I had to reset back to factory defaults. Now I am receiving an invalid IMEI on both Sims. The cell phone is acting as if the IMEI numbers are totally erased. I checked the validity of my IMEI, and they appear to be valid. When I press *06*# I get invalid device ID for both sim cards. So whats the next step repairing this? I hope there's something I can do to fix it..
