new bootroom

1. jailbroken and unlocked
2. stuck in boot loop problem all the sudden
3. no 3.1.2 SHSH on file
4. after 13 hours of running blackrain, finally got out of the boot loop problem
5. quickly install Blacksnow RC2 final as suggested here http://www.hackint0sh.org/f230/117709.htm
6. rebooted after, blackrain to tether boot fine.
7. but signal bar keep saying searching, and phone become awfully slow. when click "about" in general, phone freezes very time.
8. uninstalled blacksnow rc2 final. rebooted, tether booted fine. everything back to normal.

now the million dollar question: is there any risk for me to be stuck in bootloop again?
