We announced earlier today that Verizon was rolling out the latest and greatest build of Android for the Galaxy S5! Every Root user understands that when Verizon releases an update they will always patch previous known root methods. This is still the case with the latest update for the Verizon Galaxy S5. Some users are also reporting that once you receive the OTA update not only will you not be able to regain root, you also will not be able to downgrade. It appears that the signing keys have been changed.
It seems as if TowelRoot will not be updated to support this new version of Touch Wiz either. This phone was incredibly challenging to root in the first place so who knows how long it will be until we see another root method for the new update. If you are interested in keeping root on this device my advice to you is to stay away from the update. If you really want to run the updated version of Touch Wiz on your Galaxy S5 just be patient developers will have a prerooted Rom available for you to flash soon.
