Crucial Warning: Confirm your model number and regional branch before downloading. Global units (TA-1119, TA-1121, TA-1128) use 00WW firmware, whereas China units (TA-1131) use 00CN firmware. Files with ANT prefixes belong to the MediaTek Nokia 1 Plus and cannot be flashed on this device. Packages in this archive require Nokia Online Service Tool (OST LA).

Compatibility & Bootloader Notes
Reflashing stock firmware using Nokia OST LA writes official factory partitions. Stock flashing does not modify bootloader unlock state. Factory servicing through OST Tool communicates via download mode without requiring an unlocked bootloader.

Frequently Asked Questions
Both models share the same hardware base (Qualcomm Snapdragon 710, 6.18-inch display, 3500mAh battery). Nokia X7 is the Chinese domestic release (TA-1131, running 00CN firmware), while Nokia 8.1 is the international release (TA-1119, TA-1121, TA-1128 running Android One 00WW firmware).
Several third-party mirrors incorrectly label files as "Nokia X7 TA-1131 ANT-311A...". ANT is HMD Global's code for the Nokia 1 Plus, which runs on a MediaTek MT6739 processor. Flashing an ANT build onto a Snapdragon 710 device causes a boot failure due to incompatible partition structures.
Standard Nokia OST LA requires internal service center credentials. Technicians use a patched version of OnlineUpdateTool.exe that bypasses the login dialog, allowing local .zip, .mlf, and .nb0 firmware archives to flash offline.
