After re-reading MotoCache1's first post at the start of this thread, it "should" root the latest OTA if you download it. Moto's process installs BusyBox, superuser, and the files necessary for root, and then flashes a custom recovery image (SPRecovery). If you're rooted and don't want to repeat this process with every OTA update I suggest you install a custom recovery to block it.i havent gotten this update yet ... if i get ot and install, will this method still work to reroot the fone ?
The only caveat to this would be if the latest update changes the recovery back to stock, but so far I haven't heard of it anywhere with this update. Most of these issues seem to occur with the "one-click" rooting methods. While those methods do work to root your phone, they leave you pretty much dead in the water for the next update if you don't know how to block it.
