For anyone looking to grab a HTC One M8 internationally or on Sprint, you'll be happy to know that they both have a build of TWRP (Team Win Recovery Project) already. The recovery for both models are now available for download. The Sprint HTC One M8 is available on TWRP's website, while the International HTC One M8's is not, but it is available on XDA for those interested in grabbing it for their HTC One M8. Word of caution though, these files are not interchangeable, meaning you cannot flash the Sprint HTC One M8's TWRP file on a Verizon HTC One M8, it will brick the device, and you'll have a beautiful Aluminum paper weight afterwards. Not something we want, right?
Of course you'll need to head over to HTC's website, htcdev.com, so you can unlock the boot loader. We likely won't see TWRP available for the HTC One M8 on Verizon or AT&T for quite sometime, since those carriers don't like to have unlock able boot loaders, which is fine - we kind of understand why. However, T-Mobile's will likely come locked and you can unlock it through htcdev.com as you could with the original HTC One. But we'll still have to wait for TWRP or another recovery to be available for the T-Mobile HTC One M8. Which since it doesn't launch until April 11th, it could be quite a while.
