Crucial Warning: Model number and branch/subsidy tag (Generic CID50, MSTLA, LATAM, MOVSTLA, RETUS, AMZ/CCAWS, TESCOEU) must both match the device before flashing. Matching model number alone is not sufficient.

Frequently Asked Questions
The model number is printed under the SIM tray or shown in Settings > About phone; compare it against the Product/Variant line on the fastboot screen (athene XT162x).
No. Cross-flashing between athene models carries regional and hardware risk, so the model number and subsidy tag on the package should match the device exactly.
No. Stock firmware replaces the system and boot images only. Bootloader lock state is controlled separately through Motorola's official unlock-token process and fastboot oem lock/unlock commands.
Most athene CFC/flashfile packages include a userdata erase step. Check the specific package's included script before flashing if data preservation is required.
That indicates a deeper brick state than standard fastboot firmware addresses, requiring a blank-flash package and a separate unbrick procedure.
