This is a custom kernel for D4/RAZR based off of the CM14.1 Kernel that was created by @stargo for Nougat. Below is the list of features this kernel adds to the Stock CM14.1 kernel:
  • Over-clocking to 1.3 and 1.4Ghz
  • Additional Governors - InteractiveX, KToonservative, Lionheart, SmartassH3 and ZZMove.
  • Additional Schedulers - ROW, SIO, SIO Plus, VR and Zen
  • IntelliPlug driver - Hotplugging while sleeping for all governors (leave governor Hotplug disabled as this overrides)
  • Additional frequency and scaling scaling options:
    • RunNGun - all frequencies between 300Mhz and 1000Mhz removed.
    • Full Scale - all frequencies (in steps of 100Mhz) enabled up to max speed kernel supports
    • *** All are labeled in the downloads section below ****
    • SELinux permissive kernels on request
  • Additional Voltage Options for 1.4Ghz frequency: HV (High Voltage), LV (Low Voltage) and ULV (Ultra-Low Voltage)

Speeds up to 1.4Ghz. I have no issues with 1.4, but mileage may vary per device. Try the ULV (Low Voltage) first. If this does not work, try the LV. If neither work, try the HV. If it's still not working, you may just have to use one that maxes out at 1.3Ghz.

I've included my SDSwap in separate zip as well here for folks who would like to swap the internal and external SD storage devices around (makes external SD card primary storage as opposed to internal). See links at the bottom. NOTE: You should NOT remove the card while booted when using this as there is no way to safely unmount when booted.

If you need to remove the SDSwap, there are three methods to do so:
  • Boot to recovery and simply reinstall the ROM you are running do NOT reinstall.
  • Upgrade to the latest ROM and do NOT reinstall.
  • Extract the the ramdisk.img file from the current ROM zip from /system/etc/kexec and overwrite the ramdisk.img on your device while either booted in recovery (mount /system first) or booted in the ROM, then reboot.


Kernel Changelog:
  • 2017-10-04: Fixed issues with Wifi from previous build
  • 2017-10-02: (REMOVED from server)Rebased and synced to upstream so lost's of bug fixes and security updates
  • 2017-02-20: Fixed issue causing install to fail.
  • 2017-02-19: Sync to upstream: 10 security fixes and one reversion. *PULLED*
  • 2016-12-11: Sync to upstream: 2 security fixes, one to patch CVE-2016-8655 the other is to patch old ABI handling.
  • 2016-11-30: Sync to upstream: Security fix to disable ION contig heap
  • 2016-11-08: Initial port to cm14.1. For previous changes, please see the cm13 thread.


SDSwap Changelog:
  • 2017-10-02: Updated for latest init changes
  • 2016-11-08: Initial release.

How come some kernels are 3.0.8 and some are 3.0.31?

I believe you are referring to dtrail's kernel's. The mainline CM kernel here has a lot of patches well past 3.0.8 and 3.0.31 but not all parts of the kernel are updated. I was working on getting it up to 101 but ran in to some problems with stability that I just never had the time to debug. So as it stands, the version it SHOWS is 3.0.8 but it's actually (along with the stock CM kernel) a bit more convoluted. :cyclops:

Hey all, another kernel update. This one is a couple of security patches. Most notably, this addresses CVE-2016-8655. :good:

Also slightly related is that you can now boot v4.10-rc1 and later mainline kernels. Not very usable right now, but UART, MMC, eMMC and WLAN work so kernel modules can be scp:ed over the WLAN. I'm still working on the CPCAP regulators and USB PHY driver for v4.11 hopefully.

I also posted the mainline kexec tools for booting v4.10-rc1 and later. Note that these modules are not backwards compatible with the SafeStrap modules in the stock kernel, so don't overwrite them! The mainline kexec tools are at muru.com linux/d4/

Sorry could not create a new thread for this as I'm noob.. Also could not attach tar.xz files it seems :p

Oops, messed up again, the kexec binary in ddroid4-mainline-kexec-0.2.tar.xz was the kexec wrapper I'm still working on for the SafeStrap boot images, the file to use is ddroid4-mainline-kexec-0.3.tar.xz for now.

Now also posted an initial version of ddroid to create installable SafeStrap images if anybody cares to go through all the hoops.

Does anyone else have boot loop issues with Droid 4? I have tried OC and non-OC custom kernels with Lineage OS 14.1 builds (unofficial and official) but every time I'm stuck to the boot loop. I can only see red M logo over and over again.

I have two Droid 4 phones and the other one is currently running Sailfish OS 2.1 so I haven't test Nougat build with it. Previously I was able to OC it with custom kernel and CM13 (Marshmallow). I don't know why I'm not able to flash custom kernels with this new Droid 4. Any ideas?

I could never use OC kernels on my Droid RAZR. I think certain SOCs are more tolerable to over clocking than others.

Thanks, good to know. Maybe I need to swap Sailfish OS to this phone which doesn't run with custom kernel. It is strange because it doesn't even work with LineageOS14.1 Custom NON-OC RunNGun Kernel.
