No such folder /flash ??? I assume you are talking KODI / CE system folders yes ?? I dont want to be messing much with Android as I really loathe that OS so much and try to avoid it as much as possible. Its why I will not entertain an Android based smart phone despite some excellent hardware platforms like Huawei gear which I really rate. I stick to my iPhones thanks as far better to use and far safer too, as well as solidly built too. But hey I digress, sorry
