Firmware for Zumo XT

Post by sefeld »

Hi, my Zumo XT won't boot due to full internal storage after OSM maps install. I have SD card and Boot Menu access (A03 → B02). I'm on Linux without working Garmin Express. Could anyone share the B348400.update file via PM? Any firmware version works. Thank you!

The file is 78.3 MB, so can't be emailed. do you have Dropbox or similar?

Thank yoy very much!

Sadly thisboot loop is worse and install from sd card works, but no change in the behaviour of the device.

I finally accepted the offer by garmin spain service and send non working unit and pay 375€ and they send me a brand new XT2 unit with 3 years of warranty.

Thanks again for your effort and time spent to share the firmare.
