Announcement from Synergy510: Announcement about the ROM's future
SaberMod Banner


Welcome to my SaberMod CM12.1 project! Inspired by wanting a faster Android experience, the ROM and kernel are both built with the SaberMod toolchain tuned for Cortex-A15 devices with NEON-vfpv4 with Graphite, O3 and GCC Optimizations. I cherry-picked useful tweaks and options from other AOSP based projects that I find useful for a more customizable experience.

Installation Instructions:

Upgrading from a previous build:
  1. Nandroid
  2. Flash the ROM
  3. Flash GApps
  4. Flash any add-ons you want
  5. Reboot into ROM

Upgrading from any other ROM:
  1. Nandroid
  2. Full wipe /system, /data and /cache
  3. Flash the ROM
  4. Flash GApps
  5. Flash any add-ons you want
  6. Reboot into ROM

Note: If you ever find yourself at the Galaxy S4 screen with your LED blinking blue, reboot back into recovery, wipe /system, re-flash and reboot.

F2FS Users! No ROM conversion is necessary.
/system is only support as EXT4, do not try to convert /system to F2FS, it will fail.
/data and /cache are supported as F2FS

How to use F2FS:
"What is F2FS?
  1. Back up all your data. You will fully wipe your phone in order to convert to F2FS
  2. Download @AntaresOne's TWRP with F2FS support
  3. Boot into TWRP
  4. Go to wipe > advanced wipe
  5. Checkbox Data or Cache
  6. Press the "Repair or Change File System" button at the bottom
  7. Press "Change Filesystem"
  8. Press "F2FS"
  9. Swipe to confirm

FAQ / Common Issues / Bug Reporting
  • What makes this different from Optimized CM12.1 or CM12.1 Nightlies?
    • The CM nightlies are the baseline that provides a fast and clean experience. Optimized CM and my SaberMod CM try to take that even further by applying our optimizations to the source code. The difference between Optimized and SaberMod is that the JDCTeam strives to provide the best, polished experience for the Galaxy S4 whereas I’m an enthusiast turning this ROM into a collection of commits and features that I find interesting that I share for you guys.
  • What is SaberMod?
    • The SaberMod team provides Android optimized toolchains and ROM optimizations. Their toolchains are based on Google’s and cherry-pick from GNU. They also offer modular optimizations that speed the Android system even further.
  • Why don’t you use JustArchi’s build optimizations?
    • The SaberMod optimizations fulfill nearly the same optimizations with a different approach. It’s redundant to include them both.
  • XXX Doesn’t work for me?
    • I have the T-Mobile variant SGH-M919 as my daily driver, so I cannot cover every aspect of the ROM. I test enough so that I can run SaberMod CM as a daily driver, but our usage patterns may vary.
Common Issues
  • How do I enable Developer Options?
    • Settings > About Phone > Tap “Build Number” multiple times.
  • How do I remove the “ # “ icon from the statusbar?
    • You could flash SuperSU as with other ROMs, or you can turn it off in the Settings. Settings > Status Bar > Superuser indicator
    • *Note: A System UI FC may occur sometime after setting this, this is normal and will only happen once.
  • Bluetooth share keeps crashing / Bluetooth won’t turn on
    • Reboot your phone. Once the ROM boots up, wait for Bluetooth to automatically turn on. Make sure you turn it off, or else it will silently crash until you repeat this process.
  • I don’t have superuser/root
    • Enable Developer Options and enable Root Access from this menu. Changes in CM make it so that I can’t set root to default, so you have to set this after every clean flash.
  • I can’t install the ViPER4Android driver!
    1. Temporarily set the kernel to "Permissive" through ADB shell or the local terminal (Enable in Dev Options)
      • su
      • setenforce 0
    2. Proceed with V4A driver installation
  • Audio/Notification lag
    • If undervolted, try raising voltages
    • If underclocked, step up the lowest clock frequency
  • WhatsApp audio lags
    • There are some errors with the S4 and CM based ROMs due to our audio driver
  • Bookmark sync will ask for you to sign in
    • Go into Settings > Account > your gmail account that you want to sync with the Browser and your Bookmarks and switch the Browser toggle until sync errors go away. Reboot to remove the statusbar notification. The Bookmark sync wasn’t intended for Android 4.4+ so that’s why there are issues.
  • I can’t power on from power off while charging
    • It’s a known issue. Just unplug, wait for the battery icon to disappear then hold power to boot. Then you can charge once the phone is booting.
How to ask for help / Bug Reporting

Here are some steps to reporting bugs. You must follow these steps to streamline the help process, and it may lead you to finding the solution.
I will eventually ask all of these questions regardless, so let’s save a post or two:
  • Did you verify the MD5sum of all packages you flashed?
  • What ROM are you coming from?
  • Coming from a previous SaberMod CM release did you try wiping /system?
  • Coming from a different ROM did you fully wipe /system, /data and /cache?
  • What else did you flash? What modifications do you have?
    • Xposed: I do not support Xposed or any of it’s modules.
    • Specify a custom kernels:
      • Check if your problem persists within the kernel thread, then come here
      • It’s possible that kernels older than the current SaberMod CM build has some incompatibilities
    • Other system modifications must be specified
  • Have you searched the thread? There’s a high possibility that a problem you have in the ROM is being discussed in the latest pages of the thread
  • Is it in the bugs list? It may be a known problem

If it's an issue no one has reported:
  • Can you recreate the issue? Try to be as detailed as possible so I can recreate it.
    • ex. I can't play mp3s in Play Music but I can in PowerAmp
  • Make a logcat!
    1. Know how to recreate the problem
    2. Acquire software to make a logcat (ADB/CatLog on the playstore)
    3. Do a fresh boot
    4. Begin a logcat via "adb logcat"/start a Catlog
    5. Let the phone settle for a bit
    6. Create the issue
      • ex. Play a song that will FC/Go to an app that FCs
    7. Stop the logcat

I'd like to thank the 37 people who have downloaded the ROM so far! Your opinions and thoughts are greatly welcomed here.

I'm getting a build ready for tomorrow with 3 new changes:
  • Tuned in-call and speaker volumes
  • Dynamic Kernel Tweaker shortcut in Settings App that replaces Performance Settings!
  • Rebuilt with cortex-a15 flags for a little performance boost

I'm doing a clean build tonight with the new build flag, so I'm hoping to give you guys something tomorrow. I've spent all day working on the Dynamic Kernel Tweaking shortcut in the Settings menu (You can check my github to find the mess in trying to get it right) but I'm very very happy to say that it's finally complete.

For the not-yet convinced on this ROM, it's just CM11 with a few additions which I will highlight in this video:

I think you undersell yourself.
I am downloading this rom and looking forward to its performance.
You have the passion to make something better.
You have learned new skills in the process.
You are now a developer.
