Hi! Thanks for your suggestion. I flashed again. Here's the screenshot: oi57.tinypic.com/a0e7mp.jpg

This is the log, if it helps:

Result: It's the same. The boot keeps repeating. The only thing different is this time (the first start up), the notice "InitialBootSetup didn't load" showed up. From then it kept rebooting after showing "Process system isn't responding."

In the log, it says "No bootdelivery to send". Does that have anything to do with my problem?
