• MRPI - Mobileread Package Installer

How to Open Apps

There are two main ways to launch apps on your jailbroken Kindle:

• KUAL: Open the KUAL scriptlet, then select the app you want to run

Manual installation is straightforward - just follow the step-by-step guides provided for each mod.

Block Amazon Tracking

→ Block Amazon Tracking Script

Amazon tracks literally everything you do, even after jailbreaking: where you click with millimeter precision, what books you open, how long you read, and more. This data is used to serve you ads and sold to advertisers.

This script blocks:

• Amazon tracking and analytics
• Kindle Store access
• UI advertisements

Clear Cached Ads

→ Clear Ad Cache Script

After blocking Amazon, you may still see cached ads in the UI. This script removes them completely.

Note: Popular reads ads require editing system files which could brick your Kindle. If you want to remove those images, commands are available at kindlemodshelf.me under the "Other Cool Stuff" section.

Custom Screensavers

KOReader by default is pretty bland, but you can customize it extensively!

One of the most popular customizations is adding custom screensavers:
