SBF files have saved more than a few people’s phones if flashing ROMs gets a little out of hand. It allows you to flash a stock image of the phone in a last case scenario and is always good to have around just in case. The DROID 3 is seeing some love with a new SBF file released, of the .906 firmware build, for download today, and you even get to choose which method you like.
For those who like the safety of a one-click method, you can download the file and let the program do it’s thing while you relax. If RSDLite is more your cup of tea, XDA developer ovelayer has that file for you as well. Either way you use, the SBF will revert your phone back to .890 if you would ever need it. Generally these are good to have around if you are a prolific ROM flasher, so head over to XDA and get the download now.
