TCL 32E5300 television archive, 6.87 MB, in RAR format. The name states only the model, but a separate entry of the same size for this set is described as a 25Q64 MediaTek MT5310 dump, so this may be the same or a related flash image; that is not confirmed here. Extract and compare it. For reflashing, read and save the existing chip with a programmer, check that the image matches the chip capacity, and confirm the main board number matches the source.
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 @hashmielecom. Enginerys does not host this file.
