reMarkable Paper Pro automatic update
The SDK for 3.16 isn’t out yet, is there a way to downgrade if I’ve accidentally upgraded?
the way the device updates is with an A/B partition setup
Basically, one of the partition is the main boot partition, and the then you have the fallback. When updating, it writes the update image to the fallback partition and starts booting from it
that’s nice
you can change the boot part with a script
can I delete the update partition?
or do it manually
I wouldn't do that if I were you
I'd say let it finish the update
Once booted,
cat /sys/devices/platform/lpgpr/root_part
and depending on the output, which is either "a" or "b", echo the other value to the root_part and reboot
for example
is the cat output is "a"
run
echo "b" > /sys/devices/platform/lpgpr/root_part
reboot
this should boot the secondary partition
the first command, yes
it doesn't remove it
it's always there as a fallback
oh so like on the next update? or just permanent
when there's a new update, it writes to the fallback, and sets it as the new root partition
while the previous install will become the fallback
i.e., say A is the current partition, update is installed to B, and now, the device boots from B, and A is the fallback
and vice versa
does updating keep developer mode?
