I was already nervous….thinking I’ve bricked my phone, but yes, the first boot takes forever! Mine took about 10 minutes!
The only thing made me calm is following the boot progress with “adb logcat” while the phone started.
The first boot showed a beatiful CyanogenMod splash screen but programs seemed to be crashing (logcat). After 20 minutes, still this splash screen.
Wiped everything with RA and reflashed CyanogenMod-6.1.0
And finally got the welcome android screen asking for my Google username!🙂
