Last update bricked my pine phone :(

[lacriz]

Just flash Jumpdrive to an SD card, boot the phone with that card and connect it to a computer and then you can access the eMMC like any removable drive to backup your data before flashing a new image (I guess you have done this already to flash Arch in the first place).

Great idea, thank you!
I just booted the pp with jumpdrive and connected it via usb to my mac.
Only the micro sd holding jumpdrive itself gets mounted in macos

So I tried

telnet 172.16.42.1

but it runs into a time out.
I wanted to run mount rootfs from telnet, but that seems impossible.



diskutil

I also tried mounting the eMMC (which I can see via the macos tool 'diskutil'):

diskutil mount readOnly /dev/disk3s2

Result:
Volume on disk3s2 failed to mount
Perhaps the operation is not supported (kDAReturnUnsupported)
