So my Garmin Fenix 6X Pro got bricked 😞


1) Device model, firmware, and HWID

  • Model: Garmin Fenix 6X Pro
  • HWID: 3291


2) How and why the device got bricked
I received the watch today. Wi-Fi was not working, so I attempted to update the firmware. Unfortunately, I flashed firmware for the wrong HWID.
Before this, the watch was otherwise fully functional � only Wi-Fi was broken, and MSM mode was inaccessible.

3) Current symptoms
  • Device only shows the firmware update screen
  • Update process gets stuck halfway
  • Will not boot into the OS
  • Garmin logo never appears


4) Does the PC detect the device?
Yes, but only in pre-boot mode
MSM mode is not accessible

5) Troubleshooting steps already attempted

  • Flashed firmware with the correct HWID
  • Flashed older firmware versions
  • Used GarminCure3 / QuickCure3
  • Tried all known button combinations


6) Garmin USB drivers installed?
Yes (latest official drivers)

8) Guides and resources already read and followed

  • How to unbrick a n�vi � step-by-step guide
  • GarminCure3 tool � the new way to create cure firmware


9) Pre-boot mode

Yes, pre-boot mode is reachable
Followed Garmin�s official pre-boot instructions

10) NV backup available?

No 😞

Any help or guidance would be greatly appreciated.
Thank you very much!
