If you are sick of using the stock ROM that comes with your device, you might be interested in installing CWM recovery on Samsung Galaxy S4 SCH-I545. WIth a custom recovery, we are able to take a factory reset just like we can with a stock recovery, but we can also do much more. One of the most popular tasks to perform with a custom recovery is flashing a custom ROM. The Galaxy S4 has many custom ROMs available; thus you should install CWM recovery on Samsung Galaxy S4 SCH-I545 to take advantage of those ROMs.
- You must have root access on the Samsung Galaxy S4 SCH-I545 before installing a custom recovery in this manner.
- You are to only install this custom recovery on the Samsung Galaxy S4 SCH-I545. Attempting to install it on a different model number — or a different device from another manufacturer — will likely result in the bricking of the device. Boot the Samsung Galaxy S4 in download mode, download the stock ROM from a trusted source online like Sam Mobile and flash that stock ROM through Odin should you find yourself with a bricked device.
BEFORE WE BEGIN
- Download the up to date Samsung USB Drivers for mobile phones. We have the link from this  page that takes you directly to the official Samsung website where you can download the USB driver for Windows PCs. Alternatively, you might be interested in installing the universal USB drivers by Koush. He has managed to put together a universal driver that works for all devices.
- Double check you have the USB Debugging Mode enabled before starting the guide. Before doing that you’ll need to know if you have the Developer Options menu unlocked. The menu is hidden by default in some earlier versions of Android. You can go to the Apps > Settings App > About Device and tap the build number 7 times.
- Now that you have unlocked the Developer Options, you can enter that same menu from the Settings. Enable the USB Debugging Mode from the Developer Options.

If that doesn’t work for your device, try pressing the Volume Up + Power keys.
