The Verdict: This is almost certainly Android firmware (an .img or .pak file) for a low-end car head unit or a portable projector stick.
The most critical part of this filename is the extension: .part3.rar. TP.SK513S.PB802 1920x1080-1G-8G-ONVO-USB.part3.rar
This file is not a standalone firmware package. It is part number 3 of a multi-volume RAR archive (usually split into parts to make downloading easier or to fit size limits). The Verdict: This is almost certainly Android firmware
This isn't random noise. This is a specification sheet turned into a filename. TP.SK513S.PB802 1920x1080-1G-8G-ONVO-USB.part3.rar
Because this file is posted without the first two parts, it is likely a "bait" file.
