Crucial Warning: Confirm the RETCN/CID11/XT1115 tag on your fastboot screen before flashing. This is the only model number and region represented in this archive — there is no evidence of any other China Moto X Pro / Nexus 6 regional variant in the source data. Rows 1 and 2 below share an identical build number and nearly identical size but are two separately-hosted uploads with no checksum confirming they're byte-identical — download either one, not both.

Shares an identical build number with row 2 below and a size within 1 MB — likely the same underlying build, but hosted separately with no checksum on either to confirm they're byte-identical. Download either one, not both.
⬇️ Download via Google DriveXT1115_SHAMU_RETCN_5.0.2_LXG22.67-7_CID11_(MobileGuru4.com).zip
A third-party (MobileGuru4.com) mirror upload of the same build number as row 1 above, hosted on MediaFire instead of Google Drive. No checksum on either file confirms they're byte-identical, so both are listed rather than merged.
⬇️ Download via MediaFireXT1115_SHAMU_RETCN_LXG22.67-7.1_cid11_subsidy-DEFAULT_CFC.xml.zip
A slightly newer build (LXG22.67-7.1) than rows 1 and 2 above (LXG22.67-7) — not a third copy of the same file. This is the only row with a supplied checksum.

Flashing Overview for Motorola Nexus 6 / Moto X Pro 2014 (XT1115 shamu, China)
- Confirm your XT1115 model number and CID11/RETCN tag
- Back up your data — mfastboot flashing wipes userdata
- Download the build above — rows 1 and 2 are likely the same build, pick either one
- Flash with Motorola's mfastboot binary, not stock Android SDK fastboot
- Verify Android version and network/SIM behavior after flashing
Expand preparation checklist for Motorola Nexus 6 / Moto X Pro 2014 (XT1115 shamu, China)
- Confirm the XT1115 model number and CID11/RETCN tag from the device label, Settings > About phone, or the fastboot screen.
- Back up any accessible user data; mfastboot flashing wipes userdata.
- Install the Motorola USB drivers and the Motorola mfastboot binary (not stock Android SDK fastboot) before attempting a manual flash.
- Use a reliable USB cable and a charged battery — this device has a non-removable battery, so a mid-flash power loss carries more risk than on removable-battery devices.
Compatibility & Bootloader Notes
Reflashing stock firmware restores the system, boot, and radio images only; it does not change the bootloader lock state. The globally-sold Nexus 6 (XT1100/XT1103 and other carrier variants) is well documented as unlockable with a plain fastboot oem unlock command and no token. Treat that same no-token unlock path as unconfirmed on this specific China-market XT1115/CID11 build — it may instead follow Motorola's token-based motorola.com/unlock process the way carrier-locked Motorola phones do. None of this affects the standard stock CFC.xml/mfastboot reflash covered on this page, which does not require an unlocked bootloader. Standard unmodified fastboot cannot correctly write these images on its own — Motorola's mfastboot binary is required.

Frequently Asked Questions
Yes — this is the same "shamu" hardware Google and Motorola sold worldwide as the Nexus 6, but in China it was retailed under the name Moto X Pro with its own model number, XT1115, and its own CID11/RETCN regional lock. Global Nexus 6 units use different model numbers (XT1100, XT1103, and others) and are not interchangeable with this build.
Either one. They share the same build number (LXG22.67-7) and are within 1 MB of each other in size — most likely the same firmware uploaded to two different hosts — but neither has a checksum to confirm they're byte-identical, so they're listed as separate rows rather than merged.
LXG22.67-7.1 (row 3) is a slightly newer build than LXG22.67-7 (rows 1 and 2) — the ".1" suffix indicates a minor follow-up build rather than a different Android version. Row 3 is also the only file in this archive with a supplied MD5 checksum.
Google's factory-image/flash-all.sh method is built for the globally-sold Nexus 6 model numbers, not this China-market XT1115/CID11 build — the two use different distribution channels for the same underlying hardware. Use the CFC.xml/mfastboot method on this page for this specific model number and CID.
