Entry for the P-650R-T1 v3 router, hardware revision 3. The RAR is only 267 bytes, which is far too small for a firmware image. It most likely contains a note, a link or an empty placeholder, so do not rely on it for recovery. A working image for this revision should be several hundred kilobytes or more. Check the hardware version on the device sticker, and keep the current configuration backed up before attempting any firmware replacement on the router.
