How To Unlock Bootloader On HTC Butterfly S (Easiest Method)

The first Butterfly was somewhat of a wasted opportunity for HTC, the limited reach and high asking price preventing the 5″ 1080p monster from becoming a global winner. Back then the company was merely trying to build up hype ahead of the launch of the HTC One and, had the Butterfly not been plagued by production issues, the strategy might have worked splendidly. Instead, the Taiwanese ended up losing sales to Sony, who delivered the Xperia Z ahead of the One, and Samsung who handled the Galaxy S4’s supply and marketing better.But people like HTC for their design and build quality and yes it is good in it.HTC also provide official bootloader unlocking for HTC Butterfly S.
