Uh-oh. It looks like Verizon and Motorola have found another way to find out if they can deny you service on a malfunctioning rooted phone. It’s been discovered that the Ice Cream Sandwich builds for the Motorola DROID 4, Motorola DROID RAZR Motorola DROID RAZR MAXX include a root checker.
When booting into the recovery, a three character notation will come up letting prying eyes know what you’ve done to your device. For instance, “qe 0/0” means your device has never been rooted, “qe 1/1” means your device is currently rooted, and “qe 0/1” means it was rooted before, but currently isn’t.
We imagine this check doesn’t come up with custom recoveries, and if you have a custom recovery then they’ll know you’re rooted anyway. We don’t like it and we know you don’t feel very different, but if Galaxy Nexus users are able to get along with the lock icon during boot-up for devices with unlocked bootloaders many people shouldn’t have an issue with this.
The only difference is that you can’t revert to an official factory state and have it all disappear and that just may be what pushes the DROID bunch over the line. What do you think of this “root check?” [via Droid-Life]
