If you are the owner of a Samsung Galaxy device, then you are no stranger when it comes to using Odin. This is an essential tool if you have to install a stock firmware, to flash a custom recovery on your phone or tablet and not only, but as you know, you won’t always receive the PASS! message on Odin.
We bet that you are here exactly due to that annoying red signal with the FAIL! message on top of it or due to the “invalid ext4 image” error that you might encounter while flashing the stock firmware on your Samsung Galaxy device. In case of not already knowing, this is an error that can be found while attempting to flash a firmware using Odin with a downgraded (and sometimes upgraded) bootloader to the one installed on a Samsung handset.
