Hello, I've looked all over and have not found an answer. I had my phone rooted before the OTA using z4root but I removed it before going to 2.2.1. After going to the newest OTA I cannot re-root using z4root or by rageagainstthecage method. When using rage I get to the mount potion and try to move superuser to the bin folder it says that the drive is full so I'm assuming I don't have rw access. I don't know what else to do as either of these methods fail. Please help! Thanks!
