[Q] R&D Test Tool (upgrade/downgrade problem)

i cant seem to find a solution with this problem of mine.. i was trying to downgrade from v21a to v10a... but every time i execute the upgrade using R&D Test Tool is unsuccessful.. always stuck on "expanding kdz file" then "not responding".. sometimes i get a message "lg mobile update is already running" i tried to search about smartflash.. but i dont know anything about fls file and the other file that is needed.. can anyone help me how to use kdz in any other way? or can i use a different software to flash kdz file?
