The note in OP is outdated and only valid for the unlock method via shorting.I read VM190 or above/22.214.171.124 & above are unrootable.
I have just received the Firestick 4k from Amazon with VM242, it is still unopened. I want to learn as much as possible before I open the box.
Does the rootability only depend on the firmware version?
Am I right saying that, as long as the firmware is below 126.96.36.199 (assuming), AND I keep it away from OTA updates before the rooting process, it is good to go?
Since Kamakiri 2 we are able to unlock without shorting, if the OS isn't updated to 188.8.131.52 (this OS patchs the new unlock method).
Keep the stick offline until you are able to try kamakiri 2.0.1 for mantis.
