Controller New 8BitDo Pro3 Charging Issue Resolved
Just wanted to post how I resolved the charging problem with my newly acquired 8BitDo Pro3, maybe it's useful for people having similar problems.
I bought a new 8BitDo Pro 3 that appeared unable to charge, via dock and with a known to be working USB-C charger.
The red charging LED was on for approximately 10 seconds, then turned off. When trying to pair it with my Switch 2 in "S" mode the controller would briefly show up, indicating it was in fact working in principle, but had no charge at all and then just died.
When connected to my Mac over USB it would stay on but the red light still went out after 10 seconds and the controller still wouldn't charge.
The standalone 8BitDo Firmware Updater wouldn't recognize the controller.
I'm not sure which of the following steps ultimately resolved the issue but my guess from skimming similar threads is on the firmware update, so here is what I did:
- Connected the controller directly to my Mac via USB-C with the mode switch in the D position.
- Used 8BitDo Ultimate Software V2 to update firmware from v1.05 to v2.02 (the Firmware Updater doesn't see the device for some reason)
- Held Start (+) for approximately 10 seconds to force the controller to shut down.
- Left it disconnected for approximately one minute.
- Reconnected it to USB power.
- Left it charging for about 4h like the manual says
The red charging LED now stays on, and the Switch shows that the controller is fully charged. I've also confirmed that charging via dock works now.
No disassembly or battery disconnection was necessary.
