Archive named only 101, packed as RAR and 3.74 MB in size. No model, brand, board number or content type can be read from the name, so the files must be identified after extraction before they are used. If firmware is inside, check that the device model and hardware version match, confirm the image size suits the target chip or partition, and store a backup of the original. Treat unlabelled archives with care and verify each file against the hardware on the bench.
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 @Schematics_Mobile. Enginerys does not host this file.
