Run Kual on K4 4.1.1
Hey everyone,
I have a Kindle 4 NT, which I downgradedfrom 4.1.4 with Kubrik to 4.11 to prevent OTA updates. I also applied the jailbreak. Now I want to install KUAL (KUAL-KDK-1.0.azw2) but it doesn't run anymore. Here are my current steps: - install mkk-20141129 - install mkk-20250419 - copy kual file to /documents. When running KUAl I get the error "This item is not signed by an authorized developer,...." Can you help me with that? |

The newer Dev Certs need the latest firmware. Why bother downgrading the firmware to avoid OTA? It hasn't had an OTA update since 2011.

I want to use my Kindle as a Dashboard, but for this I need a WIFI connection.
Whenever leave my WIFI connection on for several minutes on 4.1.4 I lose my jailbreak and MRR. |
