Advice regarding reMarkable2 encryption

Open zeigerpuppy opened this issue 4 months ago • 2 comments

I am wondering if anyone has had experience enabling encryption on reMarkable2?

I have recently updated to 3.20 and would like to enable device encryption. Enabling encryption will delete all data, but I presume it should be possible to scp the data back on to the device, and/or sync with rmfakecloud again.

Interested in any experiences with doing this. I presume the disk decryption is early in boot and that the file structure should be the same.

This would be the general plan:

  1. backup on-device files:
mkdir /home/root/backups
cp -a /home/root/.local/share/remarkable/xochitl /home/root/backups/

and scp off device

scp -r root@remarkable:/home/backups/xochitl ./localbackup/
  1. backup rmfakecloud files
  2. enable reMarkable2 encryption
  3. reboot
  4. scp files back on to device
  5. re-connect and try sync

Hey I've recently (about a 2 weeks back) selfhosted rmfakecloud and synced my RM2.

After that I reinstalled with the encryption, hacked it again so it uses my rmfakecloud instance and it synced all of my files from cloud back to the device. Everything works awesome!

I did not backup any files manually via scp nor rsync etc but it is a safeguard.

So, the steps I took:

  1. host the rmfakecloud'
  2. sync your device to it
  3. (manually backup /home/root via scp just to be sure - i did not do this because yolo and I had RCU snapshot)
  4. reinstall your RM2 with encryption
  5. enable rmfakecloud on your RM2
  6. sync
  7. enjoy!
