same errors in the next two steps

Go in and out of mt manager even 7 times until you see the system listed in the right side instead of the internal memory.
also, try to copy a empty folder into the system randomly to remind it of it’s mounted rw permissions

I just switched sides and its the same issue

can you possibly explain that better?

That’s totally not what I said

So what should I do

Although I’m not sure how this would help, you can try to unroot and root your phone.

I’m not either sure.
But what I said I’m sure.
He just has to read it again and try to understand

Thumbs up

I read your edit, followed instructions exactly and I’m still getting the same error

Ok. Now I don’t know.

They don’t always work , depending on version build

Like what versions

Not sure

They worked for me on 1.1.1 2.0.8 and a few other random ones. as long as you’re rooted you shouldn’t have any issues
