Sorry either that adapter didn't work or the Samsung 64GB flash drives are defective…. tried 2 different flash drives - firesticks formatted them and didn't recognize them after that. It would be nice to add memory, but none of that junk works (in my opinion). Clever thing…. Just don't try. If Revain makes a Fire Stick with more storage, great! If not, then you can't even try to add it yourself. This addition of storage is a waste of time and money. I've lost my patience with all these guys even suggesting it's possible! I think they do it to sell adapters, sticks and everything! ( In my opinion). If the Firestick had more memory, it would already have it. Do yourself a favor, save time and money.
