Are there efforts to make jumpdrive available for the FLX1, i found that the most reliable way to attach the Librem 5 to my desktop and it gave me the ability to simply create restore images of the entire phone, then restore the image if something went wong, by again using jumpdrive.
Those are the three files that are used I believe to make it happen as far as configuration is concerned. The forum doesn't allow sharing these type files.
