Match your exact model number (XT1600–XT1609) and the carrier subsidy tag on your original box or fastboot screen (RETUS, RETGB, VZW, VFGB, TIMBR, etc.) before flashing. Two units with a similar model number can use completely different, incompatible firmware.

How to Flash Motorola Moto G4 Play (XT1600–XT1609 harpia)
Lenovo Rescue and Smart Assistant
- Lenovo Rescue and Smart Assistant runs on Windows and flashes matching stock firmware over a USB connection.
- Bootloader mode, entered with Volume Down + Power, is required for the tool to detect the device.
- The app identifies the harpia model automatically and matches it to the correct firmware package.
- The repair process flashes over fastboot without requiring the phone to be disconnected.
- The Android version shown under Settings > About phone confirms which build is installed.
flashfile.bat / CFC XML fastboot script
- Motorola USB drivers and fastboot platform-tools are prerequisites for this method.
- Fastboot mode (Volume Down + Power) with a stable USB cable is the required device state.
- A flashfile.bat script, when included in the package, flashes every partition automatically from a command prompt in that folder.
- A flashfile.xml file requires conversion into a batch script before it can run.
- First boot duration can extend to several minutes while apps optimize.
Manual fastboot flash (advanced, partition-by-partition)
- Firmware zips for this model contain individual images such as boot.img, system.img, and modem/NON-HLOS.bin depending on the package.
- The command fastboot devices confirms detection while the device is in fastboot mode.
- Individual partitions are flashed with commands such as fastboot flash boot boot.img and fastboot flash system system.img.
- Fastboot erase cache and fastboot erase userdata wipe data and are optional for a clean state.
- Fastboot reboot restarts the device once flashing is complete.
Frequently Asked Questions
Which harpia model number and subsidy tag does my unit actually need?
Look under the battery for the model number (XT1600–XT1609), then cross-check it against the Product/Variant line on the fastboot screen — the subsidy tag shown there (RETUS, VZW, VFGB, etc.) is what determines the correct package above, not the model number alone.
Can I flash RETUS or RETGB firmware on a carrier-locked unit?
Cross-flashing between subsidies (for example VZW or VFGB to RETUS) isn't guaranteed to work and can break network provisioning or future OTA updates, so stick to the firmware whose subsidy tag matches your original carrier.
Can I upgrade past Android 7.1.1 with these files?
No. Official support for the Moto G4 Play stops at Android 7.1.1 Nougat. Anything newer would require a custom ROM, which is outside the scope of stock firmware.
What if Lenovo Rescue and Smart Assistant won't service my device?
If RSA refuses (common on modified or region-mismatched units), download the firmware matching your exact model and subsidy from the list above and flash it manually using the included fastboot script.
