Before head towards our guide, let’s have a recap on the Galaxy S6. It happens to be the 6th iteration in the Galaxy series. It came out of the curtains on March 1, 2015. Samsung gave the Galaxy S series a whole new look. Its metallic unibody design makes it one of its-own-kind device. We have a 5.1 inch QHD display on the front. A 5 MP shooter is fixed atop of this screen, a 16 MP enhanced shooter is fixed at the back accompanied by a heart rate monitor and flash light. Samsung has used its very own Exynos 7420 Chipset to power up this device. A RAM of 3 GB is fixed inside while under the hood we have a 2550 mAh battery. Out of the box, it can be found running on Android 5.0 Lollipop.

Let’s head towards the guide and learn to flash stock firmware on your Galaxy S6.

Note: At the time of writing this post, official firmwares are not available, but we expect them to come out in a week or less. However, the method to flash stock firmware and all the links will remain same.

Early Preparations

1. This guide is only for Samsung Galaxy S6 (All Variants)

Make sure that your device is exactly as mentioned above. To check out what device you have, go to Settings > More/General > About Device or Settings > About Device and match the model number. Be careful about the device model number, flashing a file on a device not listed here might result in bricking it up. In that case, we may not be held responsible.

2. Battery should be charged at least 60%!

Your device’s battery should not be weak. In case your device goes dead during the flashing process, your device may get soft bricked and you might be in need of flashing stock firmware and that will ultimately result in wiping up your data as well. So, make sure that you charge your device before you start the flashing process.

3. Use the OEM data cable to establish connection!

Always use the original data cable to establish connection between your Android device and your computer / laptop. Using ordinary data cables might interrupt the flashing process, so to avoid any mishap, you need to meet this requirement as well.

4. Backup everything!

Just to be on the safe side, you may consider backing up each and everything from your Android device. This is highly recommended so that in case anything goes wrong, you still have the access to all of your data and you can restore it immediately. Also, clean install is always recommended, that means you will probably have to wipe your device to install the new firmware. So, you may backup everything as listed below.

Backup SMS Messages
Backup Call Logs
Backup Contacts
Backup Media – Copy your files manually to your PC or Laptop.
Backup EFS – If rooted, otherwise skip this step.

5. Install Samsung USB drivers

In order to be able to establish connection between your PC and your Galaxy S4, you need to have the Samsung USB drivers installed on your PC. You can find all Android USB drivers here on our site.

6. Turn off Samsung Kies and other softwares while using Odin3!

Make sure that you turn off Samsung Kies while using Odin3 flashtool. Samsung Kies will interrupt Odin3 and will result in causing errors and may not let you flash your desired firwmrae. Also, make sure that you turn off any antivirus software you’ve installed and also disable firewall to avoid any connection and flashing issues.
