I rooted my Android (HTC Desire 2.2) permanently with z4root, and it was rooted successfully. Root checker confirmed that it has been rooted. I downloaded DATA2SD, when I opened it, superuser was installed and asked me to confirm/accept root permission for DATA2SD. It was working properly.
After a few days my phone was updated from 2.2 to 2.2.2 according to my system scheduled check for update online. After updating, I realized that DATA2SD wasn't working: it says "DATA2SD cannot work without root permission"; it never asked me to accept root permission anymore.
I then checked again with root checker and it said "No root" but when I try to root it says "Your phone is already rooted, do you want to root again?" root checker says its not rooted. SuperUser is still installed, but I don't see any root permission to accept.
Any help? What should I do? I want to unroot but can't unroot.
