Hi I recently got a second hand Kobo Touch N905B, with it's firmware at 1.9.14 (r34837). I wish to upgrade the firmware, but before I do as a general precaution and for archival purposes, I want to create a backup of the currently installed firmware. As far as I understand it, I will need to enable telnet and such, but I wish to keep the backup as similar to the factory installation as possible. I have read through these posts:

But it seems that I will need to upgrade my firmware to even enable telnet. Are there any other options to back up my firmware, while keeping the installation as close to the original as possible?
Thanks in advance.
