Q11: What is a SBF?

"SBF is a file type and stands for Single Binary File that is the older format of Motorola flash files for use with RSD lite or other flash tools.​

They include all of the code groups, header files and checksums as well as a RAM Downloader for all of the device partition images in a single file and flashed from the legacy boot loader enumerated as a flash device.​

​

The new format for all dual core Motorola devices is zip archive of fastboot images and an XML file that can be used with RSD lite to flash in a single operation or flashed as individual images using the fastboot binary and DLLs in the Android SDK from the fastboot boot loader and enumerated as an ADB device.​

​

These are entirely different modes of access and operation and SBF is both wrong and a misnomer for the firmware files for current devices.​

The fast boot interface provides far more flexibility and safety for flashing than the old flash interface and avoids all kinds of problems that would arise from managing and updating he firmware on newer chipset devices.​

​

It is an extremely important distinction to make and understanding to have about how these phones work.​

​

Please stop using SBF when referring to XML.zip files.​

The current acronym for Motorola firmware files is FXZ and means Full XML ZIP file...." -Quote by cellzealot​

​

.SBF, XML.zip and tar.gz" are Offical Motorola file extentions​
