I have a Teclast X98 Air 3G C5J6 (Dual OS 64 GB). I am wondering if anyone here have upgraded it to Mirek190 V4 or V3.
The V4 is newer but it goes back to Kitkat. Are there known problems with the V3 for the model above? Is there a good reason to use the V4 and not the V3?
Another question: Do I have to root the tablet before the upgrading or the upgrade tool roots it?
I have used both v3 and v4 and I like both. However I prefer V3 because:
1. It is faster
2. The UI is smoother
3. It’s Lollipop, the current version of Android
