Find out how to use the CyanogenMod installer for Windows on your Samsung Galaxy S4 (i9500). Will it set up CyanogenMod 12 (Android 5.0) or another version? Your time is appreciated.
It all hinges on the phone model you own. If you possess a Verizon or ATT device with an existing modified bootloader, simply download and install it (CM 12.1 is available). Without a modified bootloader, your options are limited since Samsung addressed the exploit shortly after launch. For variants where the bootloader remains unlocked, proceed as before—download and flash a custom recovery. Note: You mentioned the i9500 model; rooting, disabling the bootloader, and installing a custom recovery will let you flash any Lollipop ROM you desire.
