我想询问如何在xperia m dual上安装自定义ROM>
I want to ask how to install custom rom on Xperia M Dual
I had tried adb and fastboot command in cmd but it shows waiting for device..
Help me please I'm too frustrated
Sounds like you didn't install the proper usb drivers. Easiest way I can recommend: Boot a linux live system, install fastboot and adb and execute the commands as root.
