How to use OpenMTB Maps with 28.20

Hello,

Since beta and as well now in final version 28.20, OpenMTB maps leave the Garmin Edge 1050 unusable and locked in bootloops as stated already in the beta forum. There is no response from Garmin Support other than: Don't use non-Garmin camps. As this is only reason I chose the Garmin over a Wahoo I cannot state how unstatisfying my experience with Garmin is. Does anyone have any idea on how to get the maps working again?

thanks.

    My custom maps are also built from OSM, and as said no problems this time for me. But agree that Garmin doesn’t have the best reputation

    Just to give another datapoint - every OSM based map I've tried works without issue. Freitzkarte, my own extracts from OSM, BBBIke.org monthly extracts or custom regions and themes extracted via their website. I'm also using a few local map overlays.

    But this started to work when I've started to using Edge 1050 in a very specific way:

    1. full factory reset with data wipe

    2. connect via MTP and delete everything that Edge will let you to delete

    3. update via Garmin Connect for PC, do not install garmin maps

    4. set up as a new device via Connect for Android

    5. do not restore backups, do not install anything from connect iq store

    6. copy over your maps via MTP as .img files

    7. make sure that the only .img files you have are your custom maps, basemap and dem layer. No climb pro and trailforks.

    and you'll need to wipe your device periodically every 2-4 weeks or the crashes will be back. Had to do this 3 times during 13.14 firmware era.

    It's also not 100% bulletproof, despite doing all this dance I still had a few random 'out of memory' popups followed by a crash. Suspiciously those happen in same few specific locations.
