On May 18, 2026, SteamDeckHQ updated its coverage of the JSAUX HB0602 and HB0603 Steam Deck docks. That update did not announce a new firmware release that day. It clarified that newer units are already shipping with the updated firmware installed, so recent buyers may not need to apply a manual update.
What the May 18 update actually said
According to SteamDeckHQ, JSAUX recommends contacting support at [email protected] if you experience display or connectivity issues with these docks. The May 18 note was about current shipping firmware status and support guidance, not a fresh product announcement tied specifically to that date.
The firmware itself was released earlier and, per SteamDeckHQ’s original reporting, was intended to help with compatibility on some LG monitors and televisions. That context refers to the existing update package for the HB0602 and HB0603 docks (models without an M.2 slot), not to a May 18, 2026 launch of a new fix.
Manual updates for older units
Owners of older docks who still need the update can follow JSAUX’s Windows-based process using UpdateTool2.1.9 and the CH7217A-IMG.C002.IMG firmware image. If something goes wrong during the update, SteamDeckHQ notes that CH7217A-IMG.C001.IMG can be used to restore the previous firmware. Linux installs via Wine or Proton have not been confirmed.
The HB0602 and HB0603 docks add extra ports and display connectivity for the Steam Deck. If you are seeing black screens, missing video, or other connection problems on a unit that may not include the updated firmware, reach out to JSAUX Support rather than assuming a newly released May 2026 patch is required.
