OK, here's my google words. "Lenovo Tablet A5500H xda forums"
The first hit is https://forum.xda-developers.com/android/general/lenovo-a8-5500-hv-a8-5500-h-roms-t2836866 but I didn't find a version past Lollipop. You would have to read through to see if anyone did Android 6 or 7.
Hello i own a Lenovo Tablet A5500H which after the years became slow, so i am about to do a hard reset but before doing it i wanted to ask, is there any chance my table can get android 6 or 7 version since Lenovo stoped updating it at 4.4.2 and if yes is here anyone to tell me how to do it or to sugest me another forum for my case that they could help me to do it?
Thnx all for your time
