I recently managed to root my Samsung Galaxy S3 by following this previous answer.
However when running the SuperSU app that was automatically loaded after rooting, I get the message:
The su binary needs to be updated. continue?
Then when I click OK, it gives the error:
I wondered if the version of the SuperSU app installed by the rooting software on my PC was old, so I did this:
- Opened SuperSU app
- Went to
Settings > Reinstall[cleanup for reinstallation from Google Play]
- Went to Google Play, then installed this version of the SuperSU app.
- But running the new version then gave the same error message.
I'm not sure step 2 worked because it says: "If cleanup succeeds, this app will close automatically in a few seconds. Afterwards, please reinstall SuperSU from Google Play. Are you sure you want to continue?" But then it never closes.
I know the phone had root because I downloaded a root testing app and it confirmed it.
What am I doing wrong?
I tried a number of links (like this one) and couldn't find anything else that made sense to me. Please could someone suggest what I should be doing?
