I have the cheap Android tablet. During my experiments, I had rooted it and removed application folder. Now I can't turn on my tablet it is loading forever.
I have read about ways to load new ROM on my phone. Most of them start from uploading some apps on phone. I can't do it.
Also, I tried adb tool. But command:
adb devices don't see my device.
Is it possible to recover Android system in some if Android OS isn't started and adb tool doesn't see the device?
