[ROM][Kernel][Unofficial][5.1.1] SaberMod CM12.1 for Jflte - Build Nov 7, 2015

Synergy510 · Aug 13, 2014

Introduction

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.

FAQ / Common Issues / Bug Reporting

F.A.Q's

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
8. Send it to me over PM/Post with details on what you did

Thanks.. I will try this out

Synergy510 · Aug 14, 2014

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.

It won't allow me to access my external SD card.

It only shows /Android and /Data.

The ROM doesn't have lockscreen notifications. But I can look into implementing it if it isn't too difficult

Thank you so much. I really wanted to get the most out of the S4. It's going to last me until the S8

And regarding your external SD. Did you do a full wipe or did you flash over a previous ROM? What app are you using?

Which CM Version or nightly is this Rom based off?

Graivite · Aug 15, 2014

Must say it is a pretty fast ROM. I'm using for a few hours now and I'm quite happy with it :> Although the rom is great, there's one thing that pisses me off - when I pull down the notification bar, it shows me quick settings, not notifications coming (as it's made in other roms, that have quick settings pulled down by two fingers). I understand when there's no notifications it could shows quick settings but not now lol.

I'm building this off the stable branch of CM11, this should be based on the same sources as the M9 snapshot

I did try to implement Smart Pulldown for the notifications, so the logic should be that if there are no notifications, pulling the notification bar anywhere would result in going straight to the quick settings. I know for me Smart Pulldown isn't always as stable as it should be. Do you pull down on the notification bar as soon as the notification comes in? And could you give me an example of where this happens

Graivite · Aug 15, 2014

Let's say you get a notification. SMS from a friend, missed call or anything. You want to see who you got that from. Easiest way? Pull down the notification bar to see what is going on. Surprise! The ROM showed you quick settings instead of notifications.

Did you get what I mean?

#Edit
I do not pull down the notification bar as soon as the notification comes in. Usually I check phone like a few times for an hour. Take the phone out of my pocket to see if there are any notifications, pull down the notification bar and boom I get quick settings :<

Just tested it and it runs really fast and smooth.
No Problems so far but I couldn't test it any further cos I experienced the same with the SD Card and all my apps and themes and backup stuff are there.

The SD Card doesn't show up in the system. I'm using FX file Explorer with Root Addon.
It was a clean install with full wipe and Dalvik\Cache wipe after install with banks minimal gapps.

But man when I say the Rom is fast I really mean it.

When pulling down goes to the wrong menu, it usually happens to me right when the notification comes in. I've been trying to pulldown to see if it gets it wrong, but I'm not getting anything. Did you try messing with the settings? Try to re-apply the setting for Quick and Smart pulldowns and see if that helps.

Thank you, I was hoping it would be fast.
I downloaded FX File explorer and I can see my SD card perfectly. Can you try going into Settings > Storage and seeing if you can see your SD card from there? If you can't, I think I know what could be wrong with yours. Do you happen to know what format your SD card is in? exFat, Fat32... etc If it is exFat, then that's why and I need to apply some patches for you in the next build

S View

Synergy510 said:
Hello everyone, my latest build is available for download.

Build 08/14/2014:

Tuned in-call and speaker volumes

Updated Alucard kernel to 2.7.0d

Added cortex-a15 flags to build for a little performance boost

Added Dynamic Kernel Tweaker shortcuts in the Settings Menu! http://imgur.com/gEeUhU9

I would really appreciate if someone with an S-view cover would test to see if it works! Also any feedback, good or bad is welcomed!

Hi Syn,

S View hasn't worked for me. The ROM has not presented any sign that the S View cover was there. So I have uninstalled your ROM as S View is a key funcionality for me.

Anyway, this is fine work! Keep it up, i'm sure you'll sort out the s view issue. I'll be around checking your progress. Thanks! :good:
