– Used Windows-based computers, Odin will not run on Mac.

Again, this stock firmware is specifically for the Galaxy S6 with model number SM-G920T a T-mobile retail version only. Do not play it around on any other Samsung Galaxy S6 and variants or else you may wonder why. I warned you.
1) Extract or unzip the downloaded firmware, Odin flasher program can’t read it until you’ll get the correct file path which is in (.tar) file format.
2) Run Odin Downloader v3.10.6 flasher program.
3) Do Not check the Re-Partition checkbox. Mark check these checkboxes Auto Reboot and F-Reset Time and nothing else.
4) Reboot the phone in download mode: To reboot the Galaxy S6 into download mode , you need to turn the power off. Once completely shut down, just press and hold the Volume Down key, Home button and the Power button at the same time.
You should then prompted into a warning screen and asking you to press Volume Up if you want to continue or volume down to cancel, just simply press volume up to get into download mode. The download mode screen displays a box and say’s “Downloading.. Do not turn off target!!”
5) Connect the phone to PC when it’s only in the Download Mode screen. You should notice that the ID:COM box on ODIN will turn to blueish and will show you the port (COM) number.
6) Click on the AP button then browse to the folder where you extracted the stock firmware.
7) Hit the “START’ button if everything seems all good to start flashing.
8) Wait until see the huge word “PASS!’ and not Failed!.
9) Remove the phone from the computer once it has completely reboots.
10) Optional: perform wipe data or factory reset to again.
Fixing possible failures on Odin:
If you ain’t see the word ‘PASS!’ and it says ‘completed 0/failed 1′, all you need is just repeat the procedure above.
If it still fails, check the following again,
– Try to use other USB cable.
– Try to use other computer USB port.
– Try to use other desktop/laptop computer.
If you have bootloop or stuck on welcome screen logo on first reboot. Just perform a full data factory reset as this issues usually happens when your phone came from a modified system images, such as rooted kernels, custom recoveries and unofficial firmware and you forgot to perform wipe data before restoring to stock.
– Wait a couple of minutes as the firmware installation still refreshing.
– If it continuous on an hour, perform a factory reset via recovery.
Just hold down Volume Up, Home and Power button at the same time. Once the phone displays the recovery options scroll down using the Volume keys and then select Wipe Data/Factory reset.
