Fix SW Rev check fail device 4 binary 3

Hello everyone, today we will show you how to fix binary error sw rev check fail while flashing in samsung device.
First of all, let me clear you the reason behind this error.

If you flash outdated or older build firmware than the actual firmware in your device, you will get this error.
If your phone is running on binary 4 firmware and you flash binary 3 firmware. You will get error like this.

This means you flashed binary 3 firmware in the device having binary 4 firmware.


All you need to understand is you can’t flash lower binary firmware in the phone if your phone has higher binary version. You can’t downgrade binary but can upgrade.

Now let’s find out in which binary version your phone is running on and how to choose correct binary version firmware for your phone.

Put your phone into download mode by pressing power key, home button and volume – at the same time.
