Hi friends: First, i´m sorry for my english (i'm spanish). I have a trouble and i hope you can help me. I have instaled on my kyros MID1126 the Coby germany update, to android 4.1.1, after that,the device doesn't recognize any sd card, specifically, in settings-storage, i can see the sd-card, the total space and the available space, but the file explorer doesn't allow me to see it. I have been researching and I think that it's a usb-brick, and the solution could be to connect the tablet into fasboot mode, and with android sdk tools,to type in the comand console "enableqxdm 0", and it should fix it. My problem is that when I connect the tablet in fastboot mode, it's recognized by the pc but not by the android sdk, in fact, when i type "fastboot device" in the command console, it returns me "? fastboot". If i connect the tablet runnig android, the command "adb devices" returns me "135234252", I think in adb mode, the device is perfectly recognized, but not in fastboot mode. I have tried a lot of drivers with the same result. If someone knows how would i connect the tablet in fastboot mode, or another method to solve the usb-brick, i will be gratefull.
