Something isn't right, OP. I am having difficulty tinkering with Bluestack and Instagram.
The problem is when I install Bluestack from official download (ver 2.4.x), I can install Instagram fine but I can't use Tweaker (since it's not rooted)
And Instagram wouldn't let me create account saying "This device already has too many users"
Now If I install Bluestack rooted (ver 0.9.3), Tweaker works fine, but Instagram won't install (perhaps due to Bluestack rooted ver)
Instagram says : "This can't be installed : Error code - 2"
I googled it but got no result so problem unsolved lol
My question is : Which Bluestack version are you using, OP? Are you sure it's same one currently hosted at "bluestacks.com/download"?
And how did you tweak it without rooting it?
I mean, you said 1. download from official page 2. use tweaker
but how on earth did you tweak the official version? You look like Genious Wizard man lol
