Hi guys I'm new to the S4, but not new to rooting. I'm on MF3, unfortunately my S4 came with that update already installed. And it seems MF3 is a pain in the butt. I've successfully installed safestrap and TWRP (2.3.6 I believe). And Xposed framework. Pretty sure that doesn't matter. I've downloaded the ROMs Hyperdrive and Alpha. Is it safe to flash either of these? Any custom kernels available? And while I'm at it are there any good 4.4 ROMs? I wasn't a fan of PACMAN on the Evo LTE.
