Hi everyone, I have a Razer DeathAdder V4 Pro (RZ01-0533) — a special pro player/esports team unit with a white and black scaly pattern design (not standard retail version). The issue: Every time I run the firmware updater, it reaches 100%, appears to complete successfully, but then loops back to the same screen saying an update is required. The device firmware stays on version 1.00.04 and never reaches 1.20.00. What I have already tried: - Connecting directly to motherboard USB ports (front and rear) - Closing Razer Synapse completely before updating - Trying USB 2.0 ports instead of USB 3.0 - Forcing DFU mode (holding left + right + scroll wheel while connecting) - Re-downloading the latest firmware updater from support.razer.com - Disabling antivirus during the update Additional details: - The mouse has no standard serial number visible (pro unit) - The charging base shows no indicator light - WiFi on the device is non-functional My theory is that this pro/esports unit has a different internal hardware ID than the retail version, and the public firmware is being rejected silently by the device. Has anyone dealt with this on a non-retail unit? Is there a specific recovery tool or a way to force-flash the firmware? Any help is appreciated. I can provide photos of the mouse if needed. Thanks
