TechBeholder doesn't suggest or advise you to go with a pre-jailbroken device because the reason behind saying a big NO to such pre-jailbroken Firestick because you never know who sells it may leave some malware, virus, or tampered with the software or hardware in different ways. These malware and viruses may break your privacy and steal your data so always go with the original Firestick, and then if you are required to Jailbreak a Firestick, you can do it any time by following this guide.
