I know you guys have heard this before but I'd appreciate it if someone could help. I too let my phone update without unrooting it and WHAM....you know the rest. I refreshed my phone and tried to root again by using the zroot4 and superuser but there appears to be a problem with both apps on my phone. Was able to remove the zroot4 app but can't delete and reinstall the superuser app. I get the following message and don't know how to correct. It reads as follows:
"An error occurred and su was not updated. A zip file (su 2.3.1-bin-signed.zip) has been placed on your sd card. Please reboot into recovery mode & flash it to update your su binary". Not sure how to get into recovery mode and flash
If there is an easier way to fix this problem, it would be much appreciated if you could provide steps.
