The Duos users unfortunately don't have the luck to be supported with custom roms such as CyanogenMod, Slim Bean or any other AOSP rom, but you now have a kernel.

A member from xda-developers forums called c0bain has recently published this modified stock kernel that has some neat features. Here are some of them.


  • BLN Support
  • Rooted
  • Busybox
  • SIO default I/O Scheduler. ROW I/O Scheduler.
  • USB FastCharge support
  • Reduce battery usage: RCU_FAST_NO_HZ = ON
  • Undervolting support
  • Copiling with linaro GCC 4.8, cflags = -Os -mcpu=cortex-a9 -mtune=cortex-a15 -marm -march=armv7-a -mfpu=neon-vfpv4


  • Have the Duos variant 
  • Have CWM Recovery installed. Haven't already? Check this post. 
If you remember the Vikinger kernel for the other S4 Mini variants with the BLN support, this one now also has it. Another one of the notable features is the support for undervolting, so you can save up on some battery juice.

This time unfortunately for the other S4 Mini users, this is only available for the Duos variant as the developer said that he cannot test it on the other variants (supposedly because he doesn't own them) but hopefully in the future someone will volunteery agree to test.
