All right please no more mention of this. It is your opinion, i absolutely refute touching anything made by them, and absolutely refuse to talk about them as this is an indirect promotion they absolutely don't deserve. You are simply telling people to use their fw and thats a big no.
If you use the sd install method with the older version, it can install to nand. Or you can leave the sd card always inserted. The rest does not exist, its an unnecessary risk and worse, it promotes their behavior as it acknowledges their existence and attitude. So even if you are saying you are not, you are in practice becoming their agent. You just linked their site, that is directly giving them google search results. I will remind you that they take a cut so its not something "free", and this by exploiting the works of others like Kano and ck.
This is not a vnish thread. And vnish is never the answer, quite the opposite. But i will not discuss this here anymore. Vnish is in my boycott list, both the person(s) and whatever they say they make or support. You can make a vnish thread stating how wonderful it is, and you will not see me there saying anything about it. But this is a thread with the word Braiins OS in it. He did the same provocation before, because that's what they do.
If you insist, just like i told vnish, you will leave me no choice but to add you to the ignore list. Yes; just after vnish himself went to troll and insult in one of our groups, he was given a chance and he did behave for a few months, then he did it again plus the threats via dm, and that was the last time.
If you think someone with this attitude could not do something wrong with firmware, that is your opinion, not mine, and like i said, this is not a vnish thread. No more vnish talk, you are essentially thread hijacking by bringing this here.
The owner of the miner can do and risk whatever they want, but i do not agree that it is a viable way to install Braiins OS and nobody from Braiins will ever tell anyone to use vnish to install Braiins OS, that's ridiculous.
The only supported install of Braiins OS is with the miner running FACTORY firmware and NOTHING else. When you uninstall Braiins OS it puts factory fw and you are free to do whatever after that. Because Braiins OS is not related to any other firmware, it is not a mod, you cannot use the same methods used to remove other fw. So the easiest and simplest way is just run it from the sd card. If you DO install to nand, to remove later, you need to use bos-toolbox uninstall.
Therefore my recommendation, especially to those using x17, is to run it directly from the SD card and only install it if they are absolutely sure they want it in the nand, it makes no difference to run it from SD or NAND except saving the micro sd card for something else.
PS: The reason the latest version is not installing to NAND is unrelated to signature checks. If you want to discuss more,
come to my thread. We have derailed the OP question long enough.
