Thanks for the insight. Can you confirm it works like this:
- flash the hybris-recovery image respectively to boot_a and _b using fastboot
- reboot
- telnet to the device
- file a public key on the device
→ then proceed with dd activity via ssh?
By the way, the above command didn’t work out for me but I was able to make it work like this (ssh’d into device and as devel-su):
dd if=/dev/sda79 bs=4M | ssh myusername@
address 'cat > /mypath/dd/backup-sda79_$(date
-I).img'
As a side note, I found out that when running dd on Sailfish it seems impossible to monitor the data transfer by either calling ‘status=progress’
dd: invalid argument 'progress' to 'status'
or to view the pipe content by inserting a ‘| pv |’ as in was suggested on some forum:
dd if=/dev/sda79 bs=4M | pv | ssh potato@address
result:
bash: pv: not found
Anyway thank you very much for your help!
