I downloaded the latest version of Liberty, stuck it on my phone, and installed The clockwork bootloader and rom manager. I performed the following actions as noted in this thread
-boot into recovery via Recovery
-select "wipe data/factory reset"
-select "Yes -- delete all data"
-select "install zip from sdcard"
-select "choose zip from sdcard"
-find and select LibertyXX.zip
Now it's just been hanging on the M screen for 20+ minutes. I've pulled the battery once to restart and perform the steps noted above, but the results are still the same. It's just sitting on the motorolla logo. What steps am I missing to get my phone back up and running?
