Last update bricked my pine phone :( - lacriz - 01-24-2022
Hello,
the last time I installed updates (from the Terminal), my pine phone froze after a couple of minutes.
I waited a really long time, was using wifi and connected to power.
I finally made a hard reset (pressed the power button for 20-some seconds), started it again and got -- nothing. Just a black screen and the LED constantly on in green.
I have arch installed on the eMMC.
So, I made a full backup months ago. My bad, I know.
I still would like to know if/how I can access my data that is (hopefully) still on the phone.
Can I access some kind of boot manager during startup?
Could I make a backup of the broken phone and get my data from that backup?
Could I roll-back to some kind of restore point (this would be ideal)?
Any help is appreciated!

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)

I don't know which files system Arch uses, but maybe it's one that can't be mounted by MacOS (or not without extra steps)?

I think you are right. I can make a copy of the whole eMMC using dd on its unmounted drive, but macos cannot mount the eMMC.
I will try my luck using Linux next.
Thanks!

fwiw, by now I:
a) managed to backup individual files from my home folder using jumpdrive and connecting to a Linux machine
b) switched to postmarketOS + phosh (to try something different).
All in all I took away 2 things:
1) It is quite easy to save data from a 'bricked' pine phone
2) arch seems too 'bleeding edge' (a.k.a. unstable) for my taste

Glad it worked out! I thought MacOS could at least mount ext4, but I just checked and it doesn't even support that, so accessing most distros' file systems is probably not easily done on a Mac.
