How long (on average) does it take to flash and install a custom ROM? I rooted my desire last week and took the plunge with a custom ROM today (OpenDesire 4.0.0). I backed up successfully using Rom Manager and started the installation process. Note: I didn't clear the cache or anything so this may be the problem. The phone re-booted and now I have an Android splash screen with a light going across the word Android twice. The animated image then disappears for a split second then does the same. It looks like it's stuck in a loop. Is this just a case of the cache causing issues, or is it still installing the Rom?
