I am a plain old user of jailbreaks, I’ve used them all on every iPhone/iPad. The frustration with the ATV JB is unparralleled. I have no doubt I will eventually get it to work but it’s grueling. I am having all the same issues with seasonpass that iI had when I used Greenpoison. Impossible to get to DFU, the one time you get it to run you are not sure if you are JB because the ATV black software can’t find the device. So you do it over and over until it works.
Not fun but will be worth it, just thought I’d take a break.
