Firmware archive labelled SALWEEN BD0331 REV 1.2, 20.8 MB in RAR form, with no brand or device named. Salween appears to be a project code and BD0331 a board identifier with revision 1.2, but the name does not state the manufacturer. The archive size suggests several images or a large flash dump. Before programming anything, unpack it, examine the file sizes against the flash chips on the board, match the board marking exactly, and keep a full backup of the original chip contents.
