I've been reading around in the forums here for a few weeks now and finally decided to join. I have a A955 D2 and been wanting to upgrade it. I've been wanting to try CM7 but I can't figure out the SBF (system boot file). I don't want to brick it but I can't seem to find any real guides on how to perform a SBF flash or when you need to do a Full or partial SBF flash? I know a SBF can brick your device if you put a new on over a old sbf? or something like that? Not sure I have a hard time understanding it. I've also been looking for info about using these other roms on other networks then just Verizon? For instance I want to have my phone flashed over to prepaid Cricket or something else of that sort. Will I still be able to use my phone with them? I don't have my phone on Verizon atm I'm using it on another local prepaid carrier with unlimited phone, text, +2.5GB data for $35. Its considerably cheaper then Verizon's plan for me at least. "Please excuse my improper formatting and grammar." Phone Info: A955 D2 Sys ver. Verizon.2.3.20.A955.Verizon.en.US Android Ver. 2.2 (Froyo) Kernal: 18.104.22.168 Thanks in advance for any replies! P.S. Any reference guides for some of the terminology would be great if someone has a link to a threat I'm able to Google most of it but lots of it leads me back to these forums w/o much a definitive answer.
