Bootloader Issues

[kclive]

I wanted to use fastboot to update my TWRP, I have ADB installed, also have the Android SDK program installed, but when I connect my phone up to my computer and boot into bootloader I get a message at the bottom of the screen on my phone that says to connect usb data cable. The cable is connected, I have tried different usb ports, the drivers are all installed, but I still get that message.

Any ideas?

Try unplugging and replugging back in when in boot loader.
If that doesn't work which it should then manually enter Boot loader then plug it in.

I seen this problem b4 but can't really remember the sequence they used

I've tried both ways, no luck. When I load WUGS toolkit I can get a response from ADB devices, but it still says to connect USB data cable on my phone. If I go into ADB and try ADB devices I get no response at all and it still says to connect a USB data cable.

I don't think I have ever used fastboot and NOT seen that message the entire time. Type;

fastboot devices

Does it return with your serial number? If so, proceed to flash.

ADB works while booted in Android, or in recovery. You cannot use ADB from the bootloader. Only fastboot.

So, bootloader = fastboot devices (ADB will NOT work here even if drivers are correctly installed)

Booted into Android / Recovery = ADB devices (same deal, fastboot will not work here even if installed correctly)
