Help SBF 101. What is it and how does it work

I know we cant post links or anything to SBF files or anything like that..thats not what this thread is about..i like many others have gotten a hold of the sbf..i was playing around with my phone almost looking for a way to mess it up so i could use it..i managed that pretty quickly lol...i am pretty good with doing everything to my phone..rooting..updated to 2.2 and all of that..and i had a pretty good idea what the sbf file actually did but now i have some questions...so hopefully this thread can be a thread for general questions about the sbf not relating to where to get it or how to use it...

i was lead to believe from just about every forum that using rsd and the sbf would totally flash ur phone back to 2.1 stock like the first day you turned it on...before flashing the sbf to my phone i looked at probably every single site and forum out there that had directions..(i like to find out if there are different ways of doing stuff and want to see people experiences)...every site was the same just load rsd and the patch and then flash....well once i flashed my phone it rebooted by its self and when it turned on all i had to do was activate...everything else was still on my phone...apps...settings..wallpaper etc...i know you can go into recovery and do a data wipe and clear cache but it makes me feel like the phone is not back to 100% stock as i thought the sbf did everything..so my question is..

what exactly does the sbf do....

1. is it supposed to 100% erase everything and put it back to stock 2.1
2. are you supposed to have to manually wipe date/clear cache and then flash the sbf and if so then what is the sbf doing..

sorry for the long detailed post just really curious and with some answers im sure this thread can help a lot of people who just follow directions and arent really sure whats goin on behind the scenes with everything they do to their phone

OMG, you're screwed. Might as well go buy a new phone.


lol jk,

Pull the Battery and put it back in. Then hold Home + Pwr key. Scroll and select "Data Wipe/Factory Reset" and then reboot when its finished.


All the best,

Why would I have to do a search for it....im in no way asking for it or telling anyone where to get it...there are still threads allowed giving step by step instructions for how to use it and im not even doing that...I know how to use it....im simply asking what exactly an sbf files does to ur phone...I would like to know and im sure other people would as I have seen lots of posts from people asking why all there apps and settings r still there after using it...just always assumed it was a total reflash without having to manually go into recovery and wipe.data

nah to be honest, your post was too long and i didnt read it.


It just flashes your phone back to the way it was when you first bought it.

Obv ur not exactly sure what it does either..what u just said was the whole point of my original post


wow... I know exactly what it does.. If you know about developing and programming you know that flashing means erasing the entire internal memory and replacing it with something..


in this case that something is the origional software platform the 2.1 was released with.


It reflashes the processors "Flash" memory, not the actual memory the apps and such are stored on, therefore if you are flashing an existing 2.1 with a 2.1 sbf, you will have all of your apps still on the phone. If you are flashing a 2.2 installation with a 2.1, you will have to delete your apps or it will not start.

That's why it's an SBF (Structure-Behavior-Function). It flashes the Structure, not the phones memory that is used for fiels and apps.

it's almost scary the sheer number of people that just flashed the update without doing any sort of research whatsoever. i'm not pointing fingers at anyone in this thread in particular, but i have talked to so many people that were more concerned with being able to say "my x has 2.2" than actually understanding the process and repercussions.
