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
Bootloader Codename:U7D
Build Number: G965U1UES7DTB2
Bootloader Codename:S7D
Build Number: G965USQU6CSI2
Bootloader Codename:U6C
I understand that the digit between the two letter indicated the bootloader version.
Therefore, the bootloader version is the same for U7D
and S7D
and the U6C
is older.
However, it is not the same codename.
What is the difference between U7D
and S7D
?
I'd love to know what the diffrent letters means?
