[Android Q&A, Help & Troubleshooting] angel1998:
Hi, guys! New user here and let's start!

Well, I own a tablet which the model is Innovator 7DTB41...

I bought it from Greece!

Although I found out that model's name varies at Amazon which there is named Hipstreet 7DTB41-8GB Electron 7" (Quad Core 1.3GHz Google Certified Android 5.1 (Lollipop) Tablet 8GB -Black). I'm sure 99% that Amazon's link have right specs with the other link from E-shop that i bought it!

The images from Amazon, like volume button, power button, port micro USB, port auxiliary are the same position with my tablet! If that tells something!

At first, the tablet was rooted to remove bloatware, and I tweaked the build.prop...The tweak settings I'll write them below... the problem is that suddenly the internal storage went from (read-write) to (read-only) and when I was changed back to read-write with ES file explorer it didn't do something.. So I decided to give a reboot if this fixes the problem...After the reboot, the OS disappeared and more simple it does not boot...

Also, it has recovery and I just boot into that! The choices that were given to me is 7
