On my 9500 rooted with stock ROM, I followed the instructions to install this using Odin 3.07 and the latest .MD5 (5.08.8-i9500 if I'm reading it correctly). Booted into the download mode, connected it and ran Odin, browsed to the .MD5 file and let it rip. It seemed to go well; no error messages, everything came back OK. The phone rebooted to the screen with the red 'droid image. That all seemed to go well too and the phone rebooted again.
I have ROM Manager installed. When I go to 'Recovery Setup' it indicates that the curent recovery is ClockWorkMod 5.X.X.X. Attempting to reboot into recovery from here only causes the phone to freeze.
When I try to boot into the recovery mode from power up it's still the same stock recovery screen. It doesn't appear that anything happened. I did wipe the cache but didn't do anything else such as wipe data.
Any ideas? Any additional info I can provide to facilitate troubleshooting?
