Prerequisites: The Fundamentals of Flashing

Before diving into the world of custom ROMs, it is vital to understand that the SM-G900T requires specific preparation. Unlike modern Samsung devices that use A/B partitions, the S5 uses a more traditional partition layout, but it does have a locked bootloader that must be unlocked via a specific exploit.

Prerequisites: Read Before You Flash

Before touching your bootloader, understand these risks:

Knox Counter: Flashing custom software will trip Samsung’s e-fuse (Knox). This permanently disables Samsung Pay, Secure Folder, and warranty (though warranty is long expired anyway).
IMEI/Data Backup: Always back up your EFS partition (contains IMEI). The SM-G900T is forgiving, but a bad flash can corrupt radio settings.
Battery Health: Ensure your battery isn’t swelling. A failing battery can cause random reboots during installation.
