Backing Up Your Kindle

This guide will briefly go over how to back-up your Kindle’s partitions, allowing you to recover it if it becomes bricked.

This only works on Kindle’s which are 8th generation or OLDER, such as:

• PW2
• PW3
• KT2
• KT3
• KV
• KOA

This is because newer devices such as the KT4/PW4 have different partition layouts as well as secure boot, making it impossible to resture backed up partitions.

Prerequisites

• A computer
• A Jailbroken Kindle with KUAL installed
• kterm installed on your Kindle
• knc1’s Kindle Backup Script

Backing up your Kindle

1. Plug your Kindle into your computer
2. Download the latest kterm zip file
3. Extract the kterm folder into the extensions folder on your Kindle
4. Extract the backup-0.3.tar.gz file (knc1’s backup script) somewhere on your computer
5. Copy the esys and unjail folders to the root of your Kindle when plugged in (same place as documents folder)
6. Eject and unplug your Kindle
7. Go to KUAL > kterm
8. Type the following commands:

   cd /mnt/us/unjail
   ./mkbackup.sh
   exit
   

   The ./mkbackup.sh step may take a few minutes as it backs up your Kindle
9. Plug the Kindle back into your computer
10. There should be a backups folder, this contains your Kindle’s system images, make sure you copy it to a safe location!

If you ever want to back up your Kindle again, you can start from step 7, assuming you didn’t remove kterm or the backup script
