You can now install the CWM Advanced edition or Philz Touch Recovery on Samsung Galaxy S5 SM-G900H (Exynos) and the SM-G900 (Snapdragon) variants. The updated version of PhilZ Touch recovery to 6.26.6 has worked on International Galaxy S5 variants. The new unified (klte) basically built and work for International, Canada, Sprint, T-mobile, Verizon Galaxy S5 but due to some carrier bootloader locked issues it hasn’t perfectly tested yet, but I will try to cover for that on other Galaxy S5 when a due time comes.
If you knew about CWM (ClockWork Mod recovery) then I can be sure that you also knew Philz Touch Recovery. Philz Touch Recovery is actually the CWM recovery but added with numerous features you could ever miss in CWM such as the full touch interface and a completely configurable GUI experience. It has been tested and a well proven recovery for many phones before the Galaxy S5 exists.
