I've seen a few people say something about being stuck on flashing red lights, I'll post my experience with the Firmware update in case anyone else is in the same situation. Is it safe to redownload GHUB? I'm not sure since its given me multiple headaches in the past and this firmware update made any mouse I plug in stop working. Questions: Should I update firmware from LGS or wait for it to stablize? My aim feels a bit stuttery in games without the update (not that I would know how it is with the update LOL). Tl dr: firmware update broke my mouse and any others that I plugged in and I spent 9 hours trying to fix. I really like the g502 and want to pick up the g pro wireless, but with this kind of software I don't think I will. If I somehow get a new mouse I don't think it'll be a logitech one unless they fix their software to be better. This whole process took around 9 hours as well. It wasn't stuttery before but now it is which is weird.

Should I update it from LGS or wait a bit until it's been stabilized? I think my aim is a little stuttery in the games I play and I think its due to the firmware. I'm too afraid to download G hub but I downloaded LGS and it says that there is a firmware update.

Then once I deleted everything, it started to work. I had to download an uninstalling software(Revo uninstaller), and had to delete all traces of the file, using my keyboard numpad as the mouse. I restarted my pc and replugged my mouse multiple times, didn't work. I reinstalled g hub using the windows software. The driver was called HID mouse or something like that in device manager. The rgb lights were on as well (not blinking red). Both the g502 and any other mouse showed that it was connected, and with the g502 it showed my dpi in the bottom right, yet I couldn't move or click. My mouse stopped working, and any other mouse I plugged in didn't work either. However after that, it just stopped working. I too got stuck on the updating firmware page, so I closed the software and reopened it and it downloaded.
