I renamed the ota in the step 9 or 10 from this
tutorial
Then I cannot loggin to kindle because it cannot update.
I reset the device several time and the jailbreak seems to be still present.
However when I go to the kual and run restore. Nothing happens no reboot and I still cannot update...
I tried to launch koreader and it wont launch as well.
So I suspect that the jailbreak is half damaged or limited in the demo mode.
How can I fix this? It is still on the 5.16.1.2.1 fw.
Thanks a lot.
