INSTALLING ADB/SIDELOAD DRIVERS
The first thing you need to do before using the Toolkit is install the samsung mobile drivers on your pc. These are needed so that you can backup and root your device, flash custom recovery and perform other tasks on your device that require commands be sent from your pc.
The driver pack can be installed via option 1 from the main menu [with your device unplugged] and once the drivers are installed and the device re-connected by usb cable the drivers should set up automatically [if usb debugging is enabled]. The first time you enter odin or sideload mode in custom recovery drivers will also be installed.
If you have installed drivers and the device is not being recognised then you want to check if the drivers have installed properly:
a. Make sure you have installed the Samsung USB driver for Mobile Phones pack from the Toolkit [and rebooted your pc].
b. Boot your device in to the mode that you need to install the drivers for [adb mode with USB debugging enabled, sideload mode in recovery or download mode].
c. On your pc go to the control panel and then open the device manager.
d. Now connect the usb while watching the device manager screen. If the drivers aren’t installed properly then a yellow exclamation mark will pop up which will identify the device you just plugged in [it should have a name next to it].
e. Right click on the device in the device manager and select ‘Update driver software’. Then select ‘Browse my computer for driver software’ and ‘Let me pick from a list of device drivers on my computer’. You will be looking for SAMSUNG Android ADB Interface or SAMSUNG ADB Interface from the list. If it isn’t in the compatible hardware list then untick ‘Show compatible hardware’ and click on SAMSUNG on the left to find it.
Note: If you just see a device type list instead of compatible drivers then click on ‘Show All Devices’ then on the next screen select SAMSUNG Electronics Co., Ltd. from the Manufacturers list on the left side. You should see a SAMSUNG Android ADB Interface driver listed on the right side.
Hopefully now the driver will install and the Toolkit will be able to communicate with your device. You can restart the procedure and everything should go through normally. With the standard adb commands that are sent with your device booted normally in to Android then you may have to pull down the left notification bar with your device plugged in via usb cable, click on ‘connected as’ and swithc from Media device ‘MTP’ to Camera [PTP]. On Android 4.2 and later the first time a connection is made you will be asked [on your device] to authenticate your pc.
