VXE R1 PRO MAX

My younger brother and I bought the exact same mouse model, the VXE R1 Pro Max. However, I bought mine earlier—about a month and a half ahead of his—while he just got his last week. Yesterday, I was watching him configure his mouse settings on the official ATK Hub website, and I noticed that his firmware version is V1.25 / 3.01 (Black), whereas mine is on V1.21 / 3.00 (White). I tried checking the firmware update tool to see if there was an available update, but it says I'm already on the latest version. Is it possible to update my mouse to match his version? Thanks!
