This collection covers the Motorola Moto G4 family built on the athene platform, including XT1621, XT1622, XT1624, XT1625, and XT1626 variants powered by the Qualcomm Snapdragon 617 chipset.
These stock packages are mainly relevant for software recovery cases such as bootloops, failed modding attempts, corrupted system partitions, or restoring the correct regional software branch after using the wrong build.
For this family, the main compatibility checks are the exact XT model, the regional or subsidy tag such as RETUS, LATAM, MOVSTLA, TESCOEU, AMZ, or CCAWS, and whether the package uses Motorola’s XML-based fastboot service workflow.
Installing the correct firmware can help return the phone to a stable stock state, but it should not be treated as a guaranteed fix for every device problem.

Flashing Requirements
- A Windows PC is the safest default for Motorola XML or RSD-style firmware workflows, while fastboot-based equivalents also exist for Mac and Linux environments through XML-to-fastboot approaches.
- Required tools usually include Motorola USB drivers, platform-tools or fastboot binaries, and the matching XML-based flash workflow for packages that include a Motorola flashfile or service file.
- Back up all important data first, because stock restore work commonly includes erase steps such as userdata and cache in Motorola XML-based fastboot sequences.
- Verify the exact XT model, athene codename, CID50 branch, and any subsidy or regulatory tag before flashing, especially on LATAM, RETUS, MOVSTLA, AMZ, CCAWS, and TESCOEU packages.
How to Flash the Firmware
- Choose the exact firmware that matches the phone’s XT model and regional branch, because Moto G4 athene packages in this collection are split across XT1621, XT1622, XT1624, XT1625, and XT1626 variants.
- Extract the archive and check whether it contains Motorola XML instructions such as
flashfile.xmlor a CFC XML package structure, because that indicates the XML-based fastboot service workflow. - Install the required drivers, then boot the phone into bootloader or fastboot mode before starting the flash.
- Run the XML-based Motorola flash workflow with the matching fastboot or RSD-style method, and do not mix subsidy or regulatory branches unless the target build matches exactly.
- After flashing, expect a longer first boot than normal, then investigate only if the device still cannot complete startup or setup after an extended wait.

Frequently Asked Questions (FAQs)
Can XT1621 firmware be flashed on XT1625 or XT1622?
No. The safer approach is to match the exact XT variant and branch tags shown in the filename rather than cross-flashing another Moto G4 variant from the same athene family.
What does CFC.xml.zip mean on Motorola firmware?
It indicates a Motorola XML-based service firmware package that belongs to the flashfile or servicefile workflow used with fastboot-style flashing methods.
Why do tags like LATAM, RETUS, MOVSTLA, AMZ, CCAWS, or TESCOEU matter?
Those tags identify regional, carrier, subsidy, or regulatory branches in the package name, so they should be matched carefully to avoid using the wrong software branch on the phone.
Is Snapdragon 617 confirmed for this Moto G4 collection?
Yes. The Moto G4 athene line is documented with the Qualcomm Snapdragon 617 or MSM8952 platform across these XT variants.
Do these firmware files wipe data?
They can. Motorola XML-based fastboot sequences commonly include erase commands for userdata and cache, so a full backup is strongly recommended before flashing.
Is RSD Lite the only usable method?
No. Motorola XML packages can also be translated into fastboot command sequences, and replacement tools exist that read the XML and flash the images in RSD-style order.
Can Android 6.0.1 and 7.0 builds be mixed freely?
No. The safer approach is to stay with the exact build, model, and regional branch intended for the phone instead of treating all athene packages as interchangeable.
