Is it me being blind, or are there no folders in /system? :confused: I usually put some ringtones in the zip along with deleting some apps etc.... But I don't see a thing inside this specific zip :eek:

... did you see the system.new.dat file? This is the image file of system partition that during a flash is used to create the /system... this is the way of CM to supply flashable zip, and the same is also for CM12 official... that's all.

Yes, I saw that. Is there a way for a "normal" user to change the content of that file in a convenient way? I guess no?

I think is possible... but do not know how to... anyway every modification you have in mind, can be done with root privileges after booting the OS... so why edit a zip file and an image of a partition?

With the zip file it was just copy&paste a bit, then flash and everything was as I wanted it. Moreover, starting some weeks ago I got a problem with using songs as alarm tone, they just were silent. Flashing them directly to /system/media helped, funny enough. Copying them there, setting permissions and reboot didn't.

That's a good reason... but can't help... sorry... May be googling a bit you will find a tool to be used for your needs... good luck!!

The main problem with the Bluetooth, is when you use more than one device. If you turn one off, it will not connect to the next, without a reboot.

---------- Post added at 08:33 PM ---------- Previous post was at 08:26 PM ----------

On the 22nd, it was reported that the Bluetooth: fix stale connection when pairing to another device. Pretty sure this isn't fixed yet.

Hey Guys, I don't know if it's just me but I cannot get GPS working on this rom. I'm on the nightly from 23rd, did clean install and flashed gapps. I just can't get it to lock or see how many satellites it could use. I've tried GPS status and still nothing.

Privacy disabled on maps etc.

The GPS icon is displayed. It just doesn't work.

Any thoughts, is it just me?

You need to change SELinux to permissive for Viper to work.

Search for an app called SELinux Mode Changer that is available here on XDA.

Also, after every dirty flash you need to change lpa.decode=true to lpa.decode=false in /system/build.prop or Viper won't process the audio.

This changing to permissive is safe? It wont get the system buggy?

But thanks man! I'll try this.

Btw, can you link the post for that app? There are many kinds of app like this in xda. Might as well use what you use. Thanks

Kabayan! Here - SELinuxModeChanger_v1.2.apk

Even though this app hasn't been updated sometime, it still works well with CM12.1

If you get confused on which app some of us are using and you can't seem to find it here on XDA... try Google play and check if theres a link that will point you to some thread here on XDA. Cheers man.

I'm using the phone info for samsung...
My question is, how can i flash the csc now?
I can't find something for android 5.1.1...
Thanks for your answer...

I'm guessing you read the part where it said in the Description of the app "NOTE: This app works properly with the Stock Firmware. On Custom ROM some info may not show correctly." :confused:

1. You are not going to find a csc to flash for Samsung S4 5.1.1. It does not exist. You'll have to settle for the newest csc you can find.

2. Csc flashing, regardless of rom, is always best done with odin or heimdall.

    CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5.1 (Lollipop), which is designed to increase performance and reliability over stock Android for your device.​

    Code:
    #include <std_disclaimer.h>
    
    /*
     * Your warranty is now void.
     *
     * We are not responsible for bricked devices, dead SD cards,
     * thermonuclear war, or you getting fired because the alarm app failed. Please
     * do some research if you have any concerns about features included in this ROM
     * before flashing it! YOU are choosing to make these modifications, and if
     * you point the finger at us for messing up your device, we will laugh at you.
     *
     */

    CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for CyanogenMod is available in the CyanogenMod Github repo. And if you would like to contribute to CyanogenMod, please visit our Gerrit Code Review. Your changelog is whatever was merged into gerrit.

    This is going to be a slightly long post. :) I started digging in to the Bluetooth problem, because it's been bothering me since, well, forever, both on Galaxy S4 (I9505) and S2 (I9100). Turns out its quite a mess with multiple moving parts, so to speak.

    First thing I found is that the Broadcom vendor library for Bluetooth is missing an implementation for a function called "ssr_cleanup". Our S4 uses Broadcom, so this is definitely an issue. The implementation is missing all the way upstream in AOSP sources.
    File in question: https://github.com/CyanogenMod/android_hardware_broadcom_libbt/blob/cm-12.1/src/bt_vendor_brcm.c (Google: https://android.googlesource.com/pl...libbt/+/android-5.1.1_r4/src/bt_vendor_brcm.c)

    This missing function causes the following error in the log:
    Code:
    E/bt-hci  ( 3577): Num consecutive HCI Cmd tout =2 Restarting BT process
    E/bt-btif ( 3577): bte_ssr_cleanup
    F/libc    ( 3577): Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 9919 (bluedroid wake/)
    I did my own implementation for this, mimicking the ssr_cleanup in Qualcom BT vendor lib. Compiled, replaced /system/vendor/lib/libbt-vendor.so and "Fatal signal 11" disappeared from the logs. Just as expected.

    However, this is NOT what causes the random BT disconnects. ssr_cleanup is just what happens after BTU HCI commands timeout twice consecutively.

    When BTU HCI commands time out twice consecutively, the following takes place:
    • ssr_cleanup is called
    • wait 20 milliseconds
    • "Killing the process to force a restart as part of fault tolerance" (i.e. the Bluetooth process is killed)
    So, just to test, I removed killing of the Bluetooth process from the code. Compiled, replaced system bluetooth.default.so, and ssr_cleanup/killing the process no longer happens.

    Of course, this didn't help, because things have already gone wrong when the HCI commands are timing out.

    As a note: at this point, the Bluetooth connection was stable for a random length of time (first test 3 hours, this morning a few minutes). Once the HCI commands start timing out, the connection will become unstable, possibly disconnect from my computer/car's handsfree, and it will remain so until Bluetooth is restarted. Of course, with the modifications I had implemented, the BT process was not automatically killed/restarted.

    I googled for "BTU HCI command timeout", and found that it's a common problem for at least Samsung Galaxy S3, Nexus 5, and HTC One. On StackOverflow, somebody commented that: "Of note, with specific code, the Galaxy S4 will automatically reconnect when this occurs, leading us to believe there is an issue in the BLE stack that Samsung identified and developed custom handling for." So Samsung may have implemented a way of quickly restarting the BT process without interfering with the ongoing connections. I have noticed when using I9505 GPE 5.0.1 that sometimes the BT connection becomes unresponsive for a second or two, but then just resumes without disconnecting.

    So what this boils down to is:
    • We need to find out why BTU HCI commands are timing out, and can we avoid it?
    • Figure out how to recover from this situation without breaking the Bluetooth connections
    • Or at least quickly connect/disconnect when faults occur
    Before these problems are figured out, I doubt that CM or AOSP will have reliable Bluetooth on Galaxy S4.
    Bluetooth works just fine for me on stock TW or GPE roms, but I really like CM much more because of its smoothness and functionalities...

    I have thought of replacing the CM Bluetooth with GPE implementation. However, I do not have the skills for that. Simply replacing the BT-related .so and .apk files ended up in loads of FCs.
    @AntaresOne Any idea how to start fixing this BT?

    you guys need to realize that the handfull of people contributing for jf have moved on from jf. we get no benefit from this. lots of complaining not lots of logs

    Be assured that your work and join in discussion is appreciated not only by jf owners.
    [emoji4]
    jactivelte and other Qcomm devices profit when competent people do real coding in Gerrit like you do.

    When comparing the commits of (not sure if still maintainer?) AntaresOne:
    http://review.cyanogenmod.org/#/q/owner:"Mattia+D'Alleva+%3Cantaresone%40antaresone.eu%3E"

    with

    dcd:
    http://review.cyanogenmod.org/#/q/owner:"dcd+%3Cdcd1182%40gmail.com%3E"

    the difference in numbers of merged commits is jaw-dropping [emoji6]


    Agree with you that output of logcat is more helpful than words like "X or Y not working".

    Please do stay.

    ThumbsUp button under every post is free to use in case you're in the mood to show appreciation.

    Or started own projects based on CM like "Optimized CyanogenMod 12.1 builds". I still dont get it. Why do we need a optimized Build. Why can't people just contribute those "optimizations" and fixes to the normal CM repo, so that everyone can profit.

    So, the point of sending patches to gerrit seldom makes some people acting bad saying that somebody or his work are useless. I have never been a fulltime developer with all the other things I have to do outside jf and while jf tree is practically done. You started comparisions between me and another maintainer, now seriously, do we need that? What can you get from it?

    Some people still think that CM maintainers are paid, so I'm basically nothing more than a thief since I'm committing once in a period. Now dear people, CM maintainers are NOT paid. I am in Italy, not in the U.S., situation is very bad and quality of life terribly decreased. More than "losing time" on something which doesn't give me any form of payment I focus in working on what can really give me some money back, but I'm glad to commit on gerrit when needed.

    If the dev(s)/maintainer don't read this thread (busy with work and personal life, summer etc.) is defined as useless, right no?

    Optimized ROM is how I personally want CM, and 99/100 things inside can't be added to official CM due to how these things work. I am free to do whatever I want.

    "Why do we need", remember you're not paying for what you can find here. You can't say that in respect of me, my team and whoever spends time doing something for the community. Very bad, rude and offensive. @feydakin: you used that ROM and now saying that is useless, nice job...

    How many times I asked for a log and didn't get anything? I always checked this thread daily and daily wrote here before half of June. Even if I'm not writing I'm still always checking. Don't be bad and arrogant with me only because @dcd1182 is here, but keep intact your common sense, respect in me and seriousness as it was before. I have never been arrogant or disrespectful with you.

    Lastly, just for the chronicle, my XDA activity decreased a lot since June (I have a personal life, don't know about you) and I'm sorry if I missed many messages.

    Close OT.

    Hi guys, which has been the most stable nightly so far? Thanks

    Hello,
    I would install the most recent, always contains latest patches which are not available in the older builds

    EDIT: I saw the other user said that every build after 4 August has issues with LiveDisplay. So install that one, I can't check myself if it's actually working or not at the moment
