[AC Question]

My kindle fire (I don't know what model) has stopped working after an update. I updated it and it said it needed to restart. I pressed on the button in settings to finish installing it and it said "Error!"underneath the Kindle Fire logo. After this I tried restarting my Kindle and it seemed to be working until the message "No command." appeared underneath the logo. It gave me the option to Reboot my Kindle or to Reset it to Factory Defaults. First I tried reboot and the same screen appeared, then I tried reset and the same screen appeared again. This happened multiple times. I tried using Kindle Unbrick but it couldn't detect my device. Please help!
(Ps. My device was rooted.)
