Crucial Warning: Match the exact model number (XT1621–XT1626) and the carrier subsidy tag on the device label or fastboot screen (Generic CID50, MSTLA, LATAM, MOVSTLA, RETUS, AMZ/CCAWS, TESCOEU) before flashing. Two units with a similar model number can require different, incompatible firmware.
Download Firmware for Motorola Moto G4 (XT1621–XT1626 athene)
XT1621_ATHENE_CID50_6.0.1_Stock_Firmware.zip
XT1621 ships under four different branch tags (Generic CID50, MSTLA, LATAM, MOVSTLA) with a mix of Android 6.0.1 and 7.0 builds across them; match the branch tag on the device, not just the model number.

Two separate CCAWS-tagged XT1625 packages exist at different archive sizes (1.30 GB and 1.06 GB below); verify file size against the source before flashing rather than assuming either is a straight duplicate.

Two separate CID50 XT1624 Nougat archives exist; if one fails signature verification during flashing, the other is worth trying before assuming the unit is incompatible.

Flashing Overview for Motorola Moto G4 (XT1621–XT1626 athene)
- Confirm your exact model number and subsidy/branch tag
- Try Lenovo Rescue and Smart Assistant for an automatic guided repair
- Fall back to manual fastboot flashing if RSA does not detect the device
- Match the CFC/flashfile package to your exact model and subsidy tag
- Verify Android version and network/SIM behavior after flashing
Expand preparation checklist for Motorola Moto G4 (XT1621–XT1626 athene)
- Confirm the exact XT16xx model number from the device label, Settings > About phone, or the fastboot screen.
- Identify the subsidy or branch tag (Generic CID50, MSTLA, LATAM, MOVSTLA, RETUS, AMZ/CCAWS, TESCOEU) before downloading.
- Back up any accessible user data; most athene flashing packages include a userdata wipe.
- Install the Motorola USB drivers and fastboot platform-tools before attempting a manual flash.
- Use a reliable USB cable and a charged battery throughout the flash.
Compatibility & Bootloader Notes
Reflashing stock firmware restores the system and boot images only; it does not change the bootloader lock state, which still requires Motorola's official unlock-token process and explicit fastboot lock or unlock commands. athene CFC/flashfile packages bake the subsidy tag directly into the archive filename, which is the fastest way to confirm a package matches a given unit before flashing.

Frequently Asked Questions
Check the model number under the SIM tray or in Settings > About phone, and compare it against the Product/Variant line on the fastboot screen (athene XT162x).
Cross-flashing between athene models carries regional and hardware risk, so the model number and subsidy tag should match exactly rather than being treated as interchangeable.
No. Stock firmware restores the system and boot images only; bootloader locking or unlocking is a separate, official Motorola process.
Most athene flashing scripts include a userdata wipe, and mixing old data with a different build can cause instability even when they don't, so a full backup beforehand is standard practice.
That points to a deeper brick state than standard fastboot firmware addresses, requiring a blank-flash package and a dedicated unbrick procedure first.
