PDF document of about 908 KB whose Persian title translates roughly as a collection of Flash Tools errors. Despite being catalogued as a schematic, it appears to be a reference guide to the error messages shown by flashing software, not a circuit diagram. No device, brand or board number is named. Such a guide helps a technician interpret programmer or flasher error codes while reading or writing SPI chips. Open it in any PDF reader and cross-check its advice against the manual for the programmer you use.
