I want to root estar beauty hd quad core white (MID 7038W), it works WAY TOO BAD, it even needs long to start, i dont think that there are any roms so i think rooting can help to remove even more crap from it
If you understand "rooting estar ..." as the possibility to act as superuser in Android OS ( read: like administrator in Windows OS ) then run a temporary "root": thats 'all you need to debloat Android.
Of course knowledge of Android's system commands is needed.
