I have an LG Optimus One ( LGP500 ) running 2.2 and I rooted it using the z4root tool, version 1.0. From what I saw, back then it didn't have an unroot option. In the meantime, I did an update using the LG Mobile Tool, and I think it updated my system to 2.2.2 .
I noticed that the newer versions of z4root have an unroot option, so I upgraded my z4root from 1.0 to 1.3, to try to unroot the phone ... but I only see the
Temporary root and
Permanent root options. I tried pressing the
Permanent root and it seemed to do something, after which it returned me to my
Home. From this, I'm drawing the conclusion that rerooting did not work. I am assuming z4root needs to root, so that the unroot option is available.
Is there anyway I could unroot my phone now?
