Combination files are engineering firmwares used by factory technicians to test hardware and reset security blocks. Flashing a G925T combination file often rewrites the default baseband and NV parameters, allowing the modem to wake up.
Samsung G925T NV Data File Download and Repair Guide The Samsung Galaxy S6 Edge (SM-G925T), originally released for the T-Mobile network, remains a popular device for enthusiasts and legacy users.

This is usually due to a corrupted Non-Volatile (NV) data partition.
Altering NV data is an advanced technical procedure. Always attempt to back up whatever remains of your current EFS partition via TWRP or ADB commands before writing new files over it.
