Android 6.0 + Root for Galaxy S4! [JDC Team]


For those of you looking to experience Android 6.0 Marshmallow with full root, I have good news for you. There’s a ROM by the JDC Team (Jflte DevConnection Team) that can be installed on all AT&T, T-Mobile, Sprint, Verizon, Canadian, GT-i9505,GT-i9507, and GT-i9508 variants. (For AT&T and Verizon, you MUST have older bootloader with CWM or TWRP recovery installed!!!)

Based on Android 6.0 sources, this Android 6.0 ROM by JDC Team brings you the pure Android to your Galaxy S4.  This isn’t a CyanogenMod either so you will get all of the standard Android 6.0 features just like on a Nexus phone.

Performance is excellent and I have tested the battery life to be excellent especially with DOZE mode also working (that allows your phone to save ton more battery life on standby with Android 6.0).  Everything works out of the box including voice, data, bluetooth, etc..etc…  The camera works fine also except it sometimes force closes when switching back and forth between still and video recording but a simple restart of the camera app fixes the issue.

The only thing missing?  This ROM doesn’t support exFat format for microSD cards so make sure you format them as fat32 before using them.  Overall, this is actually one of the stable Android 6.0 ROMs I’ve tried on a non-Nexus device so definitely give it a test drive this week(end) and do let me know what you think!  But I think you will love it and finally experience Marshmallow!


Download Android 6.0 Marshmallow ROM by JDC Team (for all AT&T SGH-i337, T-Mobile SGH-M919, Sprint SPH-L720, Verizon SCH-i545, Canadian SGH-i337M, GT-i9505,GT-i9507, and GT-i9508 variants)

Download Android 6.0 Gapps

Download SuperSU

*Note – For AT&T SGH-i337 or Verizon SCH-i545, you CANNOT USE SAFESTRAP, you must have CWM or TWRP recovery installed already!

Make sure you are using CWM v. or higher to install Android 5.0+ Lollipop ROMs! Also you can use TWRP v2.6.3.3 or higher.  You can update your CWM recovery using ROM Manager app on Play Store or TWRP Recovery using Goo Manager on Play Store.  If having trouble, you can update manually, see our CWM/TWRP Recovery for Galaxy S4.  For AT&T or Verizon with Loki, see How to Update with TWRP v2.8.4.0!

To install, reboot into recovery, make backup ROM, wipe data/factory reset, install ROM, install Gapps, install SuperSU and reboot.  (If for some reason you end up in a bootloop or get force-closed keyboard error on boot, reboot into CWM recovery, go to Mounts & Storage->format /system.  For TWRP, go to Wipe->Advanced Wipe->Wipe /system.)
