I'm trying to sbf my phone (which I have done successfully before). After the process is complete, my phone will not reboot. I still get the white text, even when I pull the battery and power on. Any ideas on what to do? I was previously on an old version of Apex for 2.2. I wanted to restore an old back up so that I could get to stock for the update, but I chose the wrong file and something got messed up, hence the need for sbf.
