Does this method works for huawei ascend y511-u30?
i tried this method and got into fastboot mode by 'adb reboot bootloader' which then look like "=>fastboot mode..." on device screen bottom, but i get "..." in response only 'fastboot oem unlock UUUU....' and 'fastboot oem get-bootinfo'. else 'fastboot devices' and 'adb devices' are working well.
any idea what i'm missing. i installed drivers i found stored on device and in device manager, it's shown as "android composite adb interface". i tried updating drivers from 'sdk' but they didn't worked.
any idea, what i'm missing?
