XPERIA XZ1 Compact Firmware Versions and Security Patch Levels Reference

XPERIA XZ1 has model number G8441 in all markets but Japan DoCoMo, where it is known under SO-02K. The internal product name is "lilac". There are three product variants:


lilacGLOBAL-LTE4AG8441All unlocked and carrier-branded devices, except in US/Japan
lilac_docomoDOCOMO-LTECASO-02KJapan DoCoMo branded devices.
lilac_us_ssUSSS-LTE4AG8441Unlocked US devices.


Additionally, there are 43 G8441 customization versions and 1 SO-02K. You can see your customization version by dialing *#*#7378423#*#*, then going to 'Service info', 'Software info'  and 'Customization Version' will have actual number (something like 1310-4371_R8B). XPERIA Companion checks this customization version and will query the server for updates for that specific version.
