INSTALLING ADB/FASTBOOT DRIVERS
The first thing you need to do is install the adb/fastboot drivers on your PC. These
are needed so that you can unlock your bootloader, root your device, flash a custom
recovery and perform other tasks on your device.
If you have tried installing the drivers automatically from the toolkit (Universal adb
driver pack from cwm) and you are having problems then try the following:
a. The easiest ones to use are called PdaNet for Android, download and run the
installer from http://pdanet.co/a/ and follow the instructions to install. Make
sure the device is booted into Android but NOT connected via the usb cable. You
will need to goto Settings, Developer options and tick USB debugging during this
process to allow adb to work.
To show the Developer options screen if hidden go to the Settings, About screen
and click on build number at the bottom 7 times until it says you are now a
developer. Then go to Settings, Developer options and tick USB debugging.
On Android 4.2.2 and later, after the adb drivers have been installed you should
get a pop up on your device to Allow USB debugging [authenticate] the pc. You may
need to turn on the devices screen and unlock it to see it. Tick ‘Always allow’
then click ‘ok’ to authenticate the pc. If you do not see this unplug/re-plug the
usb cable with the screen on and screen unlocked and it should appear.
NOTE: You can uninstall pdanet later without the process removing the drivers.
b. After adb drivers have been installed boot to FastBoot Mode [device reboot
options screen] to check fastboot drivers are installed.
Manual checking/installing: Goto the Control Panel on your PC and open the Device
Manager. This is so you can see if the FastBoot/Sideload drivers are installed.
c. If drivers are not installed or there is an exclamation mark next to the device:
Plug the device in to a usb cable directly connected to your motherboard. In the
Device Manager a new item, usually called Android 1.0 should pop up in the list.
Right click on the device item then left click on Update Driver Software. Select
‘browse my computer’ and then ‘Let me pick from a list’. If no adb interface driver
appears in the list then untick ‘Show compatible hardware’ and find the Android or
Samsung adb interface driver. If you cannot find either of these click Have Disk,
browse to the Toolkit install folder, drivers folder, click on android_winusb.inf
and click Open. Click OK and select Google ADB Interface.
You can use the same procedure to install the correct driver if your device is in
adb/fastboot/sideload mode and the Toolkit is not detecting it.
NOTE: If you are still having problems setting up the fastboot drivers then read
the following guide which may help you (http://bit.ly/tldgE9).
