I currently have stock 2.1 rooted with rom manager installed. I used the DMupdater to obtain root two days ago and everything worked fine and had SP recovery on it. I then installed rom manager and flashed to clockworkmod. Being OCD about everything, I rebooted and clockworkmod came up. Rebooted again and it went back to the regular exclamation point inside a triangle picture instead of clockworkmod. I then flashed SP recovery using Rom Manager and then flashed back to clockworkmod. Again, worked the first time, but after that, it keeps going back to the regular recovery console instead of clockworkmod. Update: If any of you rooted your phone using the Easy Root program from the market or DMupdater (the beta posted at Droid Life) and are having problems with Clockworkmod, you need to reflash SPRecovery console using the tried and true method in all the root guides. You don't have to go all the way through the guide, you just need to get to the point where you use RSD Lite to flash SPRecovery onto the phone. From there, you can then use Rom Manager to flash Clockworkmod back onto the phone and it will "stick" from now on once you have used RSD Lite to flash SPRecovery onto the phone. I was having an issue where the first time after flashing Clockworkmod using Rom Manager, it would boot just fine into Clockworkmod. Subsequent attempts would bring me back to the exclamation point inside a triangle meaning no Clockworkmod was detected. Seems to be the only fix for this is to use RSD Lite to flash SPRecovery onto the phone. From there, you can then use Rom Manager as normal. Hope this helps some of you who may be having issues.
