Small RAR entry labelled for the P-660HW-T1 router at hardware version 2. Its size of 271 bytes means it cannot hold an actual firmware image. It is probably a text pointer, a link or an incomplete upload, so treat it as informational only. A real recovery needs a full firmware file that matches the v2 hardware. Check the device label carefully before loading any image, and note that version 3 hardware uses different firmware that must not be mixed up with this one.
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 @afsbiosfree. Enginerys does not host this file.
