Hi,
And thank you for all that work

I have a couple questions. I have a "brand new" kindle 11th gen running 5.15.1, and if I perfectly understand what I have to do while reading the posts, questions and replies, still I am not familiar at all with this device and its software, and fear to ruin something.
1.1/ If I understand well, the best would be to upgrade it to 5.16.2.1 before attempting the jailbreak, right?
1.2/ What about 5.16.2.1.1 ?
That I can do, thanks to the links templates posted in #1.
For now, the device is like out of its box, not connected to an amazon account.
I don't want to connect it to the wifi to prevent updates.
2/ But, if after the JB I want to connect it to the amazon account, what should I do to prevent a firmware update?
Sorry if it is a stupid question answered thousand times in other threads.
I had a look in other places, but the information I got looked outdated to me. Once again, I don't want to ruin it, just got it running normal, having access to the amazon library while being root on it.
Thanks again to the team!
