Hi,
I updated my Edge 130+ to the latest FW 2.90, waited until the battery was fully charged, disconnected (used "eject").
Usually, it takes some time (seconds) for the device to realize it's not in "mass storage" mode. After that, it restarts.
But after the latest update, the unit did not restart. It stayed on the "mass storage" screen for more than 10 minutes. So I followed https://support.garmin.com/en-SG/?faq=VFyA9sBX9Z70ciuBTrgwq5
It didn't help and now it's stuck on the splash screen.
I tried to repeat the reset flow (holding the power button for 10s). No change.
Plugged it into the PC and Mac, but the device was not found.
My device is still under warranty but not sure if it can be applied here.
Thx a lot.
