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.

Compatibility & Bootloader Notes
Stock firmware replaces the system and boot images only. Bootloader lock state is controlled separately through fastboot oem lock/unlock commands and Motorola's official unlock-token process, not by flashing firmware.
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.
- Record the branch/subsidy tag shown on the fastboot screen.
- Install Motorola USB drivers and fastboot platform-tools.
- Back up accessible user data before flashing.
How to Flash Motorola Moto G4 (XT1621–XT1626 athene)
Lenovo Rescue and Smart Assistant (recommended for most users)
- Install Lenovo Rescue and Smart Assistant on a Windows PC
- Power off the phone, hold Volume Down + Power to enter the bootloader, then connect it via USB
- In the app, select Motorola and choose the software repair/rescue option — it should detect the athene model (XT1621, XT1622, XT1624, XT1625 or XT1626) automatically
- Confirm the repair and let the tool download and flash the matching stock firmware over fastboot without disconnecting the device
- Once it finishes and the phone reboots, confirm the new Android version under Settings > About phone
flashfile.bat / CFC XML fastboot script
- Install the Motorola USB drivers and fastboot platform-tools on your PC, then extract the athene firmware package matching your exact model and subsidy tag (for example XT1622 TESCOEU or XT1625 CCAWS)
- Boot the phone into fastboot mode (Volume Down + Power) and connect it with a reliable USB cable
- athene CFC packages bake the subsidy tag into the filename itself, for example XT1621_ATHENE_LATAM_7.0_NPJS25.93-14-15_cid50_subsidy-LATAM_CFC.xml, so confirm that filename matches your model and subsidy before running flashfile.bat from a command prompt in that folder
- If only the .xml file is provided, convert it to a batch script and run the generated script; it writes the same gpt, bootloader, radio and system partitions the manual method below flashes individually
- Let the device reboot once the script completes; first boot can take a few minutes while apps optimize
Manual fastboot flash (advanced, partition-by-partition)
- Extract the firmware zip and identify the individual images you need: gpt.bin, bootloader.img, boot.img, system.img, and any modem or vendor partitions included in your specific package
- Boot into fastboot mode and confirm the device is detected with fastboot devices
- Flash the partitions in order, for example fastboot flash partition gpt.bin, fastboot flash bootloader bootloader.img, fastboot flash boot boot.img, then fastboot flash system system.img
- Optionally run fastboot erase cache and fastboot erase userdata for a clean start; this wipes data
- Reboot with fastboot reboot and confirm the boot-image or bootloop issue is resolved
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.
That indicates a deeper brick state than standard fastboot firmware addresses, requiring a blank-flash package and a separate unbrick procedure.
