I realized that you cannot install firmware with older bootloader version than the one in the device.
To do things more correctly and safely, I want more fully understand the bootloader codename meaning.
Here are diffrent bootloader codenames, that appear in different three Build Numbers.
Build Number: G965FXXU7DTB4
Build Number: G965U1UES7DTB2
Build Number: G965USQU6CSI2
I understand that the digit between the two letter indicated the bootloader version.
Therefore, the bootloader version is the same for
S7D and the
U6C is older.
However, it is not the same codename.
What is the difference between
I'd love to know what the diffrent letters means?
