I have a Samsung S6 that displays "Security Error: This phone has been flashed with an unauthorized software and is locked ..... "

No network service, it keeps searching.
It was unlocked with Tmobile Device Unlock app.
The imei is intact.

I have flashed with various stock roms with Odin, and also with Kies.

Any other idea on how to resolve this?

You need to flash the official rom
