I've bought a couple of android M8 TV boxes from eBay from different sellers. One has a wizard the seller has installed into the root DIR making recovery easy if things go wrong. This wizard lets you install lots of streaming sites etc in XBMC so very useful.
The spare device I have is rooted already, but even using "super user" I'm unable to copy the file into the root dir. I simply don't have write access.
What's the easiest way to put a file into the root dir? (I obviously need to allow write access, then block again once it's transferred.)
Thanks in advance for any help.
