LG archive of 9.14 MB with a Persian name meaning several models of car player, pointing to a collection of LG car audio firmware or memory dumps. Specific model numbers are not listed, so open it and match file names to your unit. Technicians use such dumps to restore head units stuck at boot, after a failed update or with corrupted memory, by writing a flash or EEPROM chip with a programmer. Back up the original chip first and check that capacity matches the image.
