If you have bought the Samsung Galaxy S4 and yet you are still not contented with the default features of your phone or the add-ons provided by your carrier, then, this will come as a good news for you. According to Android Police, the CyanogenMod 10.1 nightly ROM build is already available for Sprint and Verizon releases of the Galaxy S4.
After successfully publishing nightly ROM builds for the T-Mobile, Canadian LTE and AT&T variants of the smartphone, the two big carriers are now getting their own. The Sprint and Verizon nightly can be downloaded at CyanogenMod’s official webpage.
Although CyanogenMod is known for delivering reliable upgrades, we at The Droid Guy cannot guarantee that it will be glitch-free. The source also warns that the nightly built is “not for the faint of heart” reasoning that both models only have one flashable ROM currently available.
Thus, it is highly recommended for users to wait for a more stable release instead since the CyanogenMod 10.1 is about to reach its final release candidate stages anyway.
Moreover, the installation, if not properly done, can really damage the system of your device. So, if you are not familiar with the process or you have trouble understanding the technicalities involved in using the modification tools, it is highly advised that you not proceed with it.
However, if you are really excited about upgrading your device using the developer tools, there is no stopping you as long as you do not forget the Gapps.
Just click the appropriate keyword below to acquire the modification tools for your device:
Sprint (designated as jfltespr in the site)
Verizon (with the code jfltevzw in the site)
In addition, the source mentioned that the Galaxy S4 owners who are using the U.S. Cellular carrier will get their share of nightly mod. You can keep track of the new releases of the developer through their download section here.
