Where are the instructions to sbf from a phone that won't boot up? I have another set of instructions that don't fit my situation.
You can try this - probably won't work, but just takes a second to try:
1. Make sure you do NOT have an "update.zip" file on the root of your SD card
2. Boot into stock recovery (power/x, then search button)
3. Select apply update zip option
4. Will error out (since there's no update.zip file)
5. Select reboot option
If you get lucky, might boot in to CW Recovery.
Or this:
-Boot into stock recovery by holding X while powering up
-Hit the magnifying glass on the keyboard to open recovery menu
-Highlight reboot and hit "ok" on the keyboard
-When you get the "M" screen pull the battery
-Power back up
Again, no guarantee, and actually didn't work for me when I got stuck at the M logo a while back. I had to SBF as well...
