I checked the S/N and it is definitely the xx05 9xxx variety. Interesting, I had pretty much given up on root access for this tablet since as you say it's doing about 90% of what I want it to do already, although root would be nice for some things like Titanium Backup. In the morning when I'm fully awake (it's almost 3 AM here as I type this ) I'll look up the article. Thanks again!since u also got a Fire HD 10 2019 n i notice u mentioned in the toolbox thread u been using it for a year. if u dont mind, plz check its serial number. if u purchase it in late 2019, it should look like xxxx xx05 9xxx xxxx n it is rootable.
