I have few micromax devices and I have different serial number for those in the box. But when I run the command adb devices for these devices, I get everything as 0123456789ABCDEF. Is there are way to get the proper device serial number for these micromax devices?
your problem may be incorrect drivers. if you installed correct drivers then restart adb and your phone too. if this does not help im sure you're not installed correct drivers. hope this help.
