Hello,

I will try to describe my problem succinctly. I purchased two Kindle 3s for my mother and I. Hers was a Kindle 3 Wifi + 3G model, with firmware 3.4, and mine was a Kindle 3 Wifi with firmware 3.4.2. Hers was easy to jailbreak, install mkk, KUAL, koreader, turn on wifi, attach to calibre OPDS, and start reading.

Mine worked perfectly as well, koreader was able to read books moved to my documents folder, the issue arose when connecting to wifi. I ran into the "This device is not authorized as a test Kindle" issue. This seems to be a problem with (I'm assuming) connecting to wifi with my firmware, because it works fine as long as I don't connect to wifi and the only difference between the two models is the firmware.

This is the jailbreak I am using; https://www.mobileread.com/forums/sh...d.php?t=225030

I'm assuming in order to get this to work I would need to downgrade my firmware? The only tool that I can find that does this is Kubrick but according to that dedicated thread the live USB won't boot on modern hardware. Does anyone have any ideas on what I could do to downgrade the firmware (or not get that test kindle message)?

My options seems to be:
1. Downgrade the firmware a different way, if you all would happen to know how to do that

2. Just not use the OPDS feature on calibre/koreader and never connect to wifi (annoying to have to connect to PC to move books over)

3. Just buy another kindle from eBay that shows firmware 3.4 in listing.

I will appreciate any reponses!
