Rooting via the mempodroid exploid on Acer_AV041_A510_RV28RC02_WW_GEN1 worked as far as I can see (SuperUser and Titanium Backup install and run alright).
Only problem I see is that apps like Titanium Backup and ES File explorer are not able to mount /system as rw and thus are a little limited in there actions. They do not complain on gaining su, that works.
(Re)mount commands via adb shell:
mount -o remount,rw /system
mount -o remount,ro /system
do work as expected.
Any idea's on what is wrong / missing and how to correct it?
It seems that a rw mount on / is going OK ???
