I tried dload method with BLN-L22C675B320 and with BLN-L22C675B340 FULL OTA downloaded from pro-teammt website, extracted the "download" file to the dload folder on the sd card but the update procedure does not start and I get an error message "software install failed", what am i doing wrong?
try formatting the External SD card first into XFAT, then copy the dload folder into it and then try installing again
