In the process of attempting to get Cyanogen MOD onto my HTC Hero. I rooted it successfully, and can connect with ADB.
I restarted the phone with the back key held down and get the fastboot screen. I press volume down to get to the HBoot screen (otherwise fastboot was failing to connect).
Now I run:
C:\android-sdk-windows\platform-tools>fastboot boot recovery-RA-hero-v126.96.36.199.img
and I wait. And wait. And wait. It certainly appears to be doing something in Task Manager (win 7) - it's showing some CPU activity, but how long is this step supposed to take? The longest I've waited was 1100 seconds before interrupting.
Using HTC Hero GSM.
