Firmware for the SR-T30 receiver, version 112 dated 11.09.2019, delivered as a 4.64 MB zip archive. The name does not reveal the brand, flash chip or archive contents, so extract it and check whether it holds an upgrade file or a full memory image. Such software is used to update the receiver or recover one that hangs at startup. Confirm the model on the device and its board, save a backup of the existing flash if a programmer is used, and keep power stable during the whole write process.
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 @tamirkaran_chanel. Enginerys does not host this file.
