This is how you flash to eMMC easily

[nelstomlinson]

Something isn't right: I have booted up jumpdrive, and I'm trying to use dd to restore a backup I made earlier with jumpdrive. dd starts out copying FAST, but after 10 minutes or so it hangs up, at around 10 to 20GB. Even after waiting 5 hours, it doesn't finish, and I don't have a bootable image on the eMMC.

Any idea what's causing the hangup?

To make the backup image:

Code:

sudo dd bs=1M status=progress if=/dev/sdc of=~/Pinephone.img

makes a 31.3GB disk image.

To restore it:

Code:

sudo dd bs=1M status=progress if=~/Pinephone.img of=/dev/sdc

Oddly enough, the 6GB weekly image from 12 December flashes to the sMMC just fine, never hangs.
