I used Rom Manager yesterday to try to install cwm recovery and failed to make any change. After doing it, I entered boatloader (I was originally s off and unlocked), and found that it has become s-on and locked. And I found another strange thing happened at the same time, although the security lock was seemed to be locked back. I still could overwrite my cid become supersid(I used "fastboot own readcid" and confirmed this), but can't do anything like flashing hboot or custom recovery...... until I unlock boatloader via HTC dev than I could flash recovery again. And I found that when I command "fastboot oem readsecureflag" , I suggested "secure_flag:0"(s off) but not "secure_flag:3"
And firewater s off is not useable for me. It will pop out "there isn't helluva....."
With hboot1.55 rumrunner is not useable for me either
Plz help me by these problems, thanks a lot
