Cannot find a method of flashing to EMMC that works

Hi All,
I've just received my Pinephone Convergence Edition (3GB/32GB) running PostmarketOS. I'd really like to install Mobian on EMMC. If I flash Mobian to MicroSD, the phone will boot it and it runs quite happily.
The problem comes if I want to flash Mobian to EMMC. I tried flashing JumpDrive to MicroSD, but if I try to boot the phone with that MicroSD inserted, nothing happens. And I mean literally nothing - the phone won't even switch on. I tried the flash with Etcher and again using dd, with the same result for both.
I then tried the second method from the Wiki - copy (not flash) the Mobian img file to MicroSD, insert the MicroSD, boot the phone and should see an option to flash the img file to EMMC. But I don't - sometimes PMOS just boots as normal, with no such option being presented, and other times the phone refuses to boot at all - again it won't even switch on.
I'd really rather not do a dd directly from a mounted partition on the MicroSD - does anyone have any idea why neither JumpDrive nor the other method is working, and what I can do about it?
Many thanks,
Mark
