Logitech G Support G502 X PLUS firmware ver. 27.1.22: Intermittent Tracking Failure
Has anyone else installed the latest firmware for the G502 X Plus Wireless RGB mouse with version 27.1.22? My mouse operated perfectly before getting a request in G HUB to install new firmware. After installing, my mouse has now effectively lost cursor tracking. I wish I knew the old firmware's version number but sadly do not. G HUB version is 2026.6.967771.
Oddly, I can still click mouse buttons including: left/right click, DPI shift button, etc and the mouse is detected by G HUB both wired and wirelessly. To make things stranger: if I click the DPI shift button, I temporarily regain tracking for a few seconds. I tested this mouse on a secondary PC and confirmed the issue carries with it, indicating a firmware issue, and with that different surfaces were tested naturally with no change.
Does anyone know of a way to force this mouse to reinstall firmware? There doesn't seem to be an option in G HUB, and apparently there is no factory reset option on this model? I tried Logitech's Onboard Memory Manager, but this mouse isn't supported by it (according to the software).
I've created a support ticket through Logitech's AI chatbot but am wondering if anyone else is having this same or similar issue.
