The joys of "every update breaks root" continues to rear its ugly head. If you really want root you'll probably have to SBF back to the pre-OTA version -- assuming the bootloader hasn't been updated to prevent such a sneaky tactic -- unless an easy way to root the update gets released.
i tried this on my huawei ascend y210.. i installed z4 but when i started permanent root it stays on shell root then minimize itself like nothing happened.
what's wrong? is it not compatible?
