Hi all, if you have this problem, the solution is very simple, the problem is that the Factory reset changes the system time, and the certificate used to connect to Amazon won't work with the time in the Kindle (the systems sees the certificate with a date in the future, so the certificate is invalid)
All we need to do is change the Kindle System time.
I'll work in a hack, but for now these are the steps I followed:
- Apply all updates from Amazon Page: https://www.amazon.com/gp/help/custo...deId=201504450
- Install de usbNetwork hack to kindle as described here: https://www.pcworld.com/article/2595...c_display.html
- Log in the kindle via telnet and change de time: date -s '2019-12-12 12:34:56'
That's all, now my kindle is regietered and downloads my books.
