Getting Android 6.0.1 MarshMallow on Samsung Galaxy S4

Hi Guys,

Today, we will discuss how to upgrade your current Android version to Android MarshMallow in Samsung Galaxy S4 GT-i9500.

Why Android MarshMallow?

The reason I like Android Operating System are the increasing customizability options in the Android updates. It is also the reason I and many other users have to find some ways to get Android update when our device’s vendors are not in likely mood to do so.

Today, I am focussing light on a way to get Android Marshmallow 6.0.1 in Samsung Galaxy S4 GT-i9500. I’m showcasing this article because of many different reasons. Foremost of which is, I myself own this device, and I would love to use MarshMallow on my Galaxy S4.

About Custom ROM (CM 13)CyanogenMod

First of all, I would like to specify that Custom ROM and Custom firmware are one of the same thing. Also I may refer Samsung Galaxy S4 GT-i9500 as i9500.

Android MarshMallow 6.0.1 is now available to install on Samsung Galaxy s4 GT-i9500 via the CyanogenMod 13, Custom ROM. This CyanogenMod 13 custom firmware is an unofficial release which is based on Android 6.0.1 and comes with various new and different features and customization tools that resemble Android Open Source Project (AOSP) ROM. But as this update/firmware has been developed by third-party developers, and not officially released by Samsung, it is still in beta and there may be quite some bugs, and it is possible that maybe a feature or 2 may be buggy or even not work at all.

About the Developer

The developer behind this project goes by the alias of Alberto96 and belongs to Italy. So far they have been able to get the video, audio, RIL and many other things working perfectly fine. Sadly, the stock camera app is not working; which means some users (not all) might face a problem. As the developer has been working on the build and is fixing bugs every now and then, I wouldn’t be surprised if those broken/buggy issues have been fixed by the time you finish reading and sharing this post.

Bugs and Workarounds

As the stock camera app is still buggy, just download any other camera app from the Google Play Store to use the camera, for e.g. Google Camera.

    • Try re-installing MarshMallow, might solve your problem. The developer hasn’t yet managed to rectify the camera issue.

  1. E:failed to verify whole-file signature
    need help

    • Rigs, first download the ROM again. Clean install a new ROM in PhilZ Or if using TWRP, then Wipe Cache, Dalvik, System, Data, Preload. Also check if you are using a 11 GB pit, first convert to 9 GB.

  2. My phone has no service. IMEI code is still original.

    • Phone does detect the sim. But there’s no service at all. No signal bars at all.

      • The way you are describing, it seems a hardware problem to me. Try that SIM in any other device, and check if it’s working correctly.
