You can just repeat the jailbreak using the latest SeasonPass and that will by default give you the 5.3 release… Note, however, that the 5.3 jailbreak is a tethered one so be certain you are happy with that before disturbing a working system.
Hi - when you say it is tethered, do you just mean that it needs to be plugged into the PC in order to jailbreak it? Or that you will need to plug it into the PC whenever you want to use the jailbroken functionality?
Just trying to understand, I know I had to plug mine into the PC when I used SeasonPass, but after that I’ve been able to use the ATV for over a year without having to plug it in again.
A tethered jailbreak means that you have to connect the ATV to a computer when you restart it.
You can let the ATV sleep without having to connect a computer to wake it up. Only when it actually powers down (either because you power it down or you unplug it or there’s a power failure) do you need a computer to reboot.
Since most people rarely reboot their ATVs, it’s not really much of an issue. But you will want to be able to bring a computer near to where your ATV will be plugged in since you cannot interrupt the power to move the unit. For most people, this means you’ll need a laptop.
