Hi there, i've bought this android tv box, but after a few minutes using it, it frezes and sometimes reboots it self. After this i've contacted the seller that gave me the link for a new firmware. I've copy all the files (factory_update_param.aml, refee120604-120704.zip, uboot-wyst-a11.bin, uImage_recovery ) to an SD card, power of the box, pressed the reset button and power on the box. the result is that i don't see anything in the screen and when i turn the box on, nothign appears. I'm new with android system, can someone give me a help on this? Is it possible to recover the system? Thank you.
