We haven't independently corroborated this, so for now consider it a rumor until after investigating it for yourself. Supposedly, if you take your Samsung Galaxy S5 into Best Buy you can get the firmware flashed by their Samsung Experience Shop to bring your Galaxy S5 up to Android 5 Lollipop. The source of this intel also claims that it will work with nearly any US carrier's device. The only exception is T-Mobile apparently. Here's a quote with more of the details,
A supposed Samsung Experience Shop rep posted to Reddit with details on how to get your phone upgraded to the latest version of Android. They claim you can ask a rep to flash the firmware to your Samsung Galaxy S5 even if it hasn’t started pushing out via the carrier themselves. There are a couple of caveats:
- Samsung Experience Shops are only found at Best Buy, and not all Best Buys at that. Be sure to confirm your local Best Buy has a Samsung Experience Shop before heading in.
- The rep notes that while almost all US carriers — even the small guys like MetroPCS and Boost — are capable of getting the update, T-Mobile is not. This is due to Best Buy not having a relationship with T-Mobile outside of selling prepaid phones.
- Your phone can’t be rooted and it must be on the latest official firmware. The update will fail to apply otherwise.
