Star X2121 Laser Full HD firmware dump read from a W25Q64 flash memory. The 8.00 MB file matches 64 Mbit capacity, so it requires a chip of that size. It is used to reprogram a receiver with corrupted software, for example one frozen on the startup screen or stuck in standby. Save a read of the original chip before erasing, check that your board is indeed the Laser version of the X2121 since other revisions exist, and confirm the write with a verify pass in the programmer software.
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.
