Ok, to clear up a few things;
1 if you are using a custom recovery, the ota update will fail everytime
2 if it is the same issue as with the Revo, the new update does not like old data. DO A FULL WIPE. especially if using a custom rom.
3 The root tool found in the revo forum here on AF should root the device. it worked on a few esteems and revos that i have worked on recently with the new update.
