Update ATV2 from 5.0.2 to 5.3

Hi all,

I want to update my ATV2 from fmw version 5.0.2 to 5.3, is it possible?

I read that to update the ATV with an old fmw you need to have saved the firmware signature… Is there any possibility for me to update the ATV2 to 5.3 version without risks?

If yes can you please link a tutorial/guide?

Thanks in advance

Just run the latest SeasonPass. Apple is still signing 5.3 so no saved blobs are required.
