Crucial Warning: This page shows 3 representative builds out of 11 known files across three model numbers — CID11, CID7, and CID12/CID9 below illustrate the branch-locking pattern, not the complete list of builds available for each model. Verify your device's own CID and model number against the fastboot screen before running any of the flashing methods below; a mismatched CID fails validation outright rather than just installing incorrectly.
Download Firmware for Motorola Moto X Style / Moto X Pure Edition (XT1570-XT1575 clark)
XT1572 also ships in Asia (RETASIA, CID7) and Argentina (RETAR, CID12) branches, and under both DS and non-DS filenames — see the full archive linked above for the exact one.
↓ DownloadCompatibility & Bootloader Notes
Stock firmware replaces the system, boot, and radio 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 X Style / Moto X Pure Edition (XT1570-XT1575 clark)
- Confirm the model number (XT1570, XT1572, or XT1575) from the device label, Settings > About phone, or the fastboot screen.
- Record the CID and, for XT1572, the DS (dual-SIM) tag shown on the fastboot screen.
- Install Motorola USB drivers and the mfastboot binary.
- Back up accessible user data before flashing — every method below wipes it.
How to Flash Motorola Moto X Style / Moto X Pure Edition (XT1570-XT1575 clark)
Motorola Rescue and Smart Assistant (recommended for most users)
- Install Motorola Rescue and Smart Assistant on a Windows or Mac PC — Motorola's own support site confirms a dedicated device flow for the Moto X Pure Edition.
- Power off the clark unit, 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 your exact XT1570/XT1572/XT1575 model automatically
- Confirm the repair and let the tool download and flash the matching stock firmware for your unit over fastboot without disconnecting the device
- Once it finishes and the phone reboots, confirm the Android version landed correctly under Settings > About phone and that mobile signal appears
flashfile.bat / CFC XML fastboot script
- Install the Motorola USB drivers and the mfastboot binary on your PC, then extract the clark package matching your exact model number, CID, and (for XT1572) DS tag — for example the RETLA/CID12 or RETUS/CID9 builds listed above
- Boot the phone into fastboot mode (Volume Down + Power) and connect it with a reliable USB cable
- clark CFC.xml packages bake the CID and branch tag into the filename itself, so double-check both match the fastboot screen before running flashfile.bat from a command prompt in that folder — a CID mismatch fails validation outright rather than just installing incorrectly
- If only a flashfile.xml is provided instead of a .bat, convert it to a batch script and run the generated script with mfastboot, not stock Android SDK fastboot
- Let the device reboot once the script completes
Manual fastboot flash (advanced, partition-by-partition)
- Extract the firmware zip and identify the individual images your clark package includes: boot.img, system.img, and the MSM8992 modem/NON-HLOS.bin radio partition
- Boot into fastboot mode and confirm the unit is detected with fastboot devices
- Flash only the partitions you need — for example fastboot flash boot boot.img, then fastboot flash system system.img — using images from the CID- and branch-matched package confirmed above
- Optionally run fastboot erase cache and fastboot erase userdata for a clean start on this device — this wipes data
- Reboot with fastboot reboot and confirm the boot loop or boot-image issue on this Moto X Style / Pure Edition unit is resolved
Frequently Asked Questions
Start with Rescue and Smart Assistant if you just want stock firmware back on a working fastboot connection — it handles detection and the correct package for you. Use the manual flashfile.bat or partition-by-partition method if RSA doesn't detect your unit, or you specifically need a CID/branch build RSA doesn't offer.
Motorola's mfastboot script checks the package's embedded CID against the one already programmed on your device and refuses to proceed if they don't match — the flash fails validation rather than partially installing and leaving the phone in a bad state. The fix is simply downloading the package with the matching CID, not a special recovery step.
The three methods below apply to every clark build regardless of which of the eleven files you end up downloading — CID11, CID7, and CID12/CID9 are examples of the branch-locking pattern, not a limit on which builds these steps work for. If your exact branch isn't one of the three shown above, use the archive crosslink to find it, then follow the same method here.
