The OP is clearly messing with things that (when someone reads this thread from the beginning) at some point are confusing even for an advanced user.The OP wanted to install the Debloated rom @Pretoriano80. This was in spite of me stating he should install rbox 6.2.7.1. Purely for this reason (unable to update)
Nobody was messing with anything mate. I simply advised the OP but it's his stick at the end of the day, I understand he was wanting to install one of your addons, again I advised he should learn and get the basics done beforehand
I know that you are trying to help him, so don't get me wrong, but sometimes things must be learned with baby steps and feeding him all these infos at the same time doesn't seem to help.
My points are :
- Why installing the pre-rooted (and obsolete) rom when it's so easy to install and maintain Magisk separately (and learn how Magisk works on FireTV)?
- The debloated rom might be useful after the user gained some experience and knows what he/she need on the FireTV and what not (even if afaik the maintainer doesn't provide any detailed info about what was removed)
- I would advise the OP to start with the latest full stock firmware, set the FireTV as he like and then to backup everything with TWRP (and save the backup to an external storage).
After this messing with advanced stuff will be easier and safer, that's granted.
