Hi, is it possible to Downgrade only battery firmware from 22.214.171.124 to some previous versions to then reinstall and upgrade new firmware? Why ? (see my previous post) I have a problem with a batt with an arising error that i think i dont have it any more (once i charged-dicharged batt many times) and i have a theroy that if i downgrade batt firmware and then reinstall / upgrade it again to new firmware , this error will be overrided and the warning massage will disappear. if some one knows how to do it, please help me test my theory. Thanks!!
