I’ve gathered data from multiple riders regarding the Hydrus 5205 Firmware update for the Onewheel Pint (OG) and the resulting nosedive / braking cutout issues. To track patterns, I’ve documented the Hardware Version for each reported Reddit post. Here’s what I’ve compiled so far:

Issue Recap:

After updating the OG Pint to Hydrus 5205, some riders have reported the OG Pint unexpectedly nosediving starting around speeds of 9-10 mph or cutting out while braking. These incidents occur WITHOUT PUSHBACK OR HAPTIC BUZZ.

Many of these reports come from experienced riders with hundreds or even thousands of miles on their boards, so they are well aware of how their boards behaved before and after the update.

Findings So Far:

• At the time of this post, Hardware Versions 5301, 5314 & 5326 have been linked to the Hydrus 5205 Firmware issue. (I have yet to hear of other hardware versions experiencing this problem after this FW update.)
• All affected riders were using either the Pacific or Skyline shaping profiles when the nosedive or braking cutout occurred.
• Issue might be related when the Pint battery is at or near full capacity (e.g., 90–100%). - Added 3/10/25

Important Notes:

• This data is not a full sample and may not represent the final scope of the issue.
• The goal is to log cases and identify a clear correlation.
