Kindle 3 Wifi Firmware Downgrade

[SEVRM]

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!

As long as your Kindle is not blacklisted, you can try the WinterBreak jailbreak and see how you get on with it.

Please stop spreading wrong information and sending people the wrong direction.
If you don’t know it, it is OK, nobody’s gonna get harmed by this.

WinterBreak is only for Kindle on FW starting with 5.x

Kindle Keyboard has FW starting with 3.x.


@SEVRM
You instead need to upgrade your Kindle to the latest firmware, where Amazon updated certificates. The problem you describe has nothing to do with internet though.

Also, keep in mind that Kindle 3 has lost its ability to load Amazon Store, but you can still send books (I believe) from Amazon Web (on PC or phone) to your Kindle (if Kindle is not blacklisted, that is).

The K3 series should use NiLuJe's Kindle hacks: https://www.mobileread.com/forums/sh...ad.php?t=88004

Yeah these are the ones that I used, they work perfectly, until I turn on wireless , then I get the “test kindle” message and not letting me open KUAL, I set up an OPDS server so I want WiFi to access it

Did you also install MKK bridge? (See the same page you got JB from, Snapshots)
I just remembered it needs to be installed manually

As if that will ever happen.
