As far as new ROMs that are based on Android Lollipop operating systems go, you should install the LolliOZOP custom ROM above all others. If you recognize the name ‘OZOP,’ that’s because there is another custom ROM made for the T-Mobile S5 under the same OZOP name. As we mentioned in the other post, the OZOP acronym stands for One Zip One Place and it is a unique custom ROM to the S5 smartphone. The difference is this version is based on Android 5.0 Lollipop, so you get the Lollipop features along with the Samsung TouchWiz.

Here is everything you need to install the LolliOZOP custom ROM on the T-Mobile Samsung Galaxy S5 smartphone using a custom recovery that you installed earlier and a computer. We always recommend you transfer the ROM files from your computer to the internal storage SD card because it’s the safest way for you to transfer your data. From there you will upload the ROM from your internal storage SD card from within the new recovery environment.

You must have a custom recovery installed on the Samsung Galaxy S5 T-Mobile smartphone before you can install a custom ROM using this guide. You can choose from any version of custom recovery that you can find available, and it does not have to be our guide. However, our steps in the tutorial are for people who are using Team Win’s TWRP Recovery. We are aware that our guide shows you how to install ClockworkMod Recovery, but we recommend updating to TWRP Recovery when it becomes available for your device because it is the better custom recovery image to be running. ClockworkMod Recovery — developed by renowned hacker Koushik Dutta — is no longer an active custom recovery image. In fact, TWRP is the only recovery partition worth considering unless you are installing a CyanogenMod-based custom ROM and would like to try the CyanogenMod Recovery instead.
