Press Fn+Left cursor to see if there are any errors shown on the console, or else change the last line in /home/root/android-root/start from /init to
strace -ff -F -tt -s 200 -o /data/logs/log-init /init
Then run /start, be patient, press Fn+Left to see the console, then press Ctrl+Alt, and while keeping these pressed press Menu (release), Home (release), Menu(release)... until you see a line with all sorts off options. This is while keeping Ctrl+Alt pressed all the time. When you see this line, keep Ctrl+Alt pressed and then press I to exit Android gracefully. Now look at the logfiles in /home/root/android-root/data/logs to see what the problem is.
