AndroidUtility version 165 packaged as a 269 MB ZIP archive. Despite sitting in a firmware index, it is a software toolkit for Android phones rather than a laptop dump or diagram. Tools of this kind are generally used for servicing phones, such as reading device information, flashing firmware or handling lock-related tasks over USB. Scan the archive with antivirus before running it, read the included instructions, and back up the phone data and partitions before performing any write operation on a device.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @mrepairo. Enginerys does not host this file.
