Quick Fix for "This device is not authorized as a test Kindle"

Gh0u1L5 · 02-12-2016, 02:34 AM

EDIT: ('・ω・')Thanks to knc1 and NiLuJe, now I figure out that the actually useful operation I did was just restarting my Kindle. However when I tried to find a quick fix for this error, all I got was "reinstall the mkk". So I'll keep this thread here to help someone like me.

Hello everyone, I am not sure whether my experience can provide you any help or inspirations but I guess it should be better to share it here.

I had my KT2 jailbroken with firmware 5.6.5, and then I upgraded to 5.7.2. However, because I have different Amazon accounts, so I deregistered for using another account. No doubt I got the error "This device is not authorized as a test Kindle by the developer of this item". Because I only have KUAL installed without any extensions, and 5.7.2 blocked install bins through "Update Your Kindle", so I actually cannot do anything. Even diags mode requires access command line on KT2.

However, I noticed that, those bin files on root directory seems deleted directly by the system after I ejected Kindle from my computer. So I tried to transfer the JailBreak-1.14.N-FW-5.x-hotfix bin file via USB cable and press power button for a while to reboot the Kindle immidiately. It works! Now I get my KUAL back!

So, good luck, hopefully I can help anyone here.

Changes in registration **always** destroys MKK.

But a restart of the device should restore it automatically.

Maybe we have scared people away from not touching 'reset' so much that they don't want to touch the (far too close) 'restart'.

For those with shaky fingers - use the power button.
Press and hold the power button until the three choice panel pops up:
Cancel | Restart | Turn off screen
You can hardly go wrong with those choices.

And if for some reason you can't see that panel -
keep on holding the power button down until the display (or led) flashes at you - then it will restart regardless of the pop panel.
