I had a problem back then with the speaker when I connect a headphones with mic the other person cant hear me, can you check it?

My wife called me whilst on my Samsung N4 headphones and I could hear her. My advice to anyone is ensure your on BOB4 both modem and bootloader. Format the SYSTEM and install CM12.1, whilst still in TWRP 3.02, format DATA, CACHE, INTERNAL STORAGE and reboot. Let it install for the first time and let it set itself up with the local directories etc. Once it's settled down, reboot into TWRP 3.02 and FLASH GAPPS from http://opengapps.org/.

Reboot and let it settle for the first time. Then carry on. Once you have done that, any traces of SAMSUNG has been wiped from your device and should be completely free of any possible issues from moving from STOCK to CM12.1

what version of TWRP? For this ROM you should have at least version 2.8.7.0. The link in my sig for CM13 modems also contains links to where you can get the latest TWRP for 910F/910G


If you're after a more updated rom, this ROM is discontinued - the updated one is here CM13 by Agsola

The most stable build from that thread at the moment is This one by Agsola (there are a few devs in the thread)

Phone is restarting when im trying to make a call or receive one. Anyone knows what is happening?

You need to ensure your on modem and bootloader BOB4. Make sure your TWRP is 3.02 and you have cleaned your phone COMPLETELY by formatting CACHE, DATA, INTERNAL STORAGE. If you leave STOCK on your INTERNAL STORAGE you will get errors. Moving from one ROM to another needs a FULL CLEAN install to ensure no possible bugs and issues can occur.

One thing I've noticed while using the Note 4 is that whenever you hit a certain amount of data usage, it doesn't work anymore. (I've turned off the data limit thing). For some reason, it will only work after you rebooted the phone again.

Can anyone help me on this? I'm on 910G

read the post one above yours.

Which is why I've posted and asked for help from members with knowledge.

I'm still using this as it is way more stable than anything that came out of CM13 in the last months. Everything is just working without any problems. The only negative (compared to the stock rom, not CM13) is that the battery drains more quickly.

I totally agree, CM13 maybe the latest version of Android, but it's still not at a point of being a day to day ROM. Although the devs have moved on, the ROM on the N910F seems perfect using the latest 9th May 2016. All the components work and that's all the devs ensure. All updates to the tree are just security updates only. It doesn't change the compatibility of the ROM.

Although I have the N910F, I can safely say I don't experience this at all. What Bootloader and Modem are you using? what TRWP are you on? When you installed the ROM did you format everything? ie CACHE, DATA, SYSTEM, INTERNAL STORAGE?

When using CM, especially when moving from SAMSUNG STOCK, the only way to ensure there is no errors is to perform the above formatting procedure.

Back to post one last thing:

Since the dev has left, this thread has gone on. The content is popular, but no one is maintaining the ROM - so theres no real help for problems.


I've talked to a mod about closing the thread, and since Gekkenhekie hasn't replied to them the thread is likely going to be closed.

If anyone with skills (even if you're a beginner!) wants to step up and take over the thread and the ROM - now is the time to announce it before this gets closed down.

I've googled around and seen that some like me have problems with gps. I've only found workaround solutions (using high accuracy wifi and mobile data apps can still pinpoint your location) but gps signal is dead. This way when offline (roaming included) gps is not working. This makes offline maps useless. Can anybody help me with this problem? Apps like GPS status show that there are no sattellites. This is a big letdown for me since I travel a lot and use offline maps all the time

There is an app called gps test. This app allows you to clear the A-GPS data and then do a update. This helped me.

    CyanogenMod is a free, community built distribution of Android which greatly extends the capabilities of your phone.

    Code:
    #include <std_disclaimer.h>

     * before flashing it! YOU are choosing to make these modifications, and if
     * you point the finger at me for messing up your device, I will laugh at you.
     */

    I'm not associated with Cyanogenmod at all and most definitely not on their paylist. Just a hobbyist.

    Download:
    http://download.cyanogenmod.org/?device=trltexx

    How to Install
    * For 910F: Use TWRP for trltexx: http://www.techerrata.com/browse/twrp2/trltexx
    * For 910G: Use TRWPR for trltedt: http://www.techerrata.com/browse/twrp2/trltedt
    (I suggest to download the .img and flash that recovery image with the tool 'flashify' )

    After that, flash the Gapps of your choice BUT MAKE SURE THEY ARE LOLLIPOP GAPPS !! And make sure the version is compatible with the Android version of the ROM (current version: Android 5.1.1)

    If you come from Touchwiz, make sure to do a factory reset and wipe Dalvik cache.

    The ROM is rooted already ! You just need to enable it, which can be done in the developer options. If you don't know how to see developer options: http://www.greenbot.com/article/245...-options-on-your-android-phone-or-tablet.html

    Again, this is very important: it is rooted already DO NOT ROOT IT YOURSELF !!! If you re-root the ROM with for example chainfire, you can expect all kinds of issue's and problems.

    Changelog:
    http://www.cmxlog.com/12.1/trltexx/

    FAQ:
    Q: Help I can't install it, my recovery says "this is for trltexx but you are on trlte".
    A: Use the correct recovery like pointed out above

    Q: Do I need to factory reset/wipe everything when I flash a new nightly ?
    A: If you were previously on CM12 I think you should be fine. However I suggest to always wipe cache and dalvik cache, if you only wipe the cache you ensure the system is not using old
    stuff. If you however are experiencing problems that no one else seems to experience, a full factory reset might be an idea.

    Q: Should I flash gapps every time I flash a new nightly ?
    A: No, only the first time you need to flash gapps.

    Q: Does this work for 910C, 910U, 910T or whatever other variant ?
    A: No. This ROM is only for 910F and 910G. Some other Snapdragons like the 910T have a ROM out, but check those forums. Exynos users like 910C are still out of luck although someone is working on a very early alpha ROM for it: http://forum.xda-developers.com/note-4/orig-development/n910c-cyanogenmod-12-sources-t3015717

    Q: I want a cooler device (or more performance).
    A: You can lower the throttle temp (cooler device) or increase it (more performance) with for example Faux clock or with this free app: https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor

    Q: Help my phone wont go into deepsleep.
    A: This could be anything. To find out what's keeping your phone awake I wrote this small tutorial: http://forum.xda-developers.com/showpost.php?p=59378043&postcount=330

    Q: My phone sleeps well but still is draining too much battery
    A: In your wifi settings in the top right corner you can pull down a menu. Click advanced and mare sure you have 'scanning always available' disabled. And then there are the usual things like in settings/accounts disable syncing for your accounts, don't enable any hardware features you don't use etc.

    Q: Can I use a custom kernel with CM12 ?
    A: Some might work. However we optimize things in the CM12 kernel specifically for CM12, so flashing a custom kernel might cause problems. So if you are on a custom kernel and reporting a problem with CM12, at least ALWAYS report that you've flashed a custom kernel when posting about some problem you are experiencing !

    Q: Does the S-pen work ?
    A: Yes, the S-pen works right out of the box on Cm12, including hovering. If you're a heavy s-pen user and want functionality like for example making a cropped screenshot (just like in Touchwiz) you can enable that with a 3rd party app like: http://forum.xda-developers.com/android/software/app-app-samsung-devices-provided-stylus-t3000448

    Q: Can I control display parameters like Contrast and Saturation ?
    A: Yes our kernel supports this app to do that: http://downloads.codefi.re/savoca/kcal/re.codefi.savoca.kcal-v1.2.apk

    Q: Can I set change the display modes, like in Touchwiz ?
    A: Yes I wrote an app for that, MDNIE tuner: https://mega.co.nz/#!uFwCAT7Z!qFzF9_2ZsJ-pHCNq8VLAD1PIiEFD9sKtLtWrazdQt5I

    Q: How can I do 60/120 hz video recording ?
    A: http://forum.xda-developers.com/showpost.php?p=61059360&postcount=2285

    Q: What bootloader and/or modem should I be on ?
    A: For 910F:Since the kernel is currently based on BOB4, I'd suggest to have both the bootloader and modem BOB4 too. You can download flashable odin files for those 2 here:
    modem: https://www.androidfilehost.com/?w=files&flid=26347
    bootloader: https://www.androidfilehost.com/?w=files&flid=26346
    For 910G: Dont know exactly, probably a bootloader from december would be best.

    *Known issue's:
    * Google camera sometimes doenst close correctly on CM12-1 and then will yield a 'cant connect to camera', I'd suggest not to use Google camera. All other cam apps work fine.
    * LTE can lose connection in some countries (Finland ?)

    CM12 Known issue's (not specific to the note 4)
    * Ringtones only work from internal SD card (not external sd card)
    * Hardware encryption not functionally
    * Fingerprint sensor not integrated just yet.

    A special thank you to @slayher and @fattire, who not only were the pioneers for CM12 on the Note 4 but also helped me out countless times with problems I've ran into, both with the code and with GIT. Without their work and help we would be nowhere.

    Enjoy !

    I just shot my first low light photo, it works !! :) Wow that has been a huge project, a lot of reverse engineering of the Touchwiz camera app and the Touchwiz camera framework to find out how it exactly works and then build it myself in C++. But the hard work paid off. Now I can't release it just yet, I'm not done yet. My current version was just made to get it going. It can ONLY do low light mode and it wont pass the photo back to the app but saves it to the disk right away, which makes the app crash. Oh and it can currently only do 1 size :) But that's all really straightforward to fix, just some work from here on. So might still need a few days, maybe even a week, but it's coming people ! It works !! :)
    41
    Over 3 weeks of reverse engineering the Touchwiz camera and rebuilding that code in Cyanogenmod have paid off: Here's a test version of the "Night Shot" mode for the camera, for you guys to try:
    First install this kernel, with the flashify app (flash 'boot image') : https://mega.nz/#!OARSwT5Z!agiFBpX7O-d3ZSd3KDwS-2Yf8NcZ-YCh49oMNaS5ujY
    And then flash this zip with your TWRP: https://mega.nz/#!DEYDgaKR!xM4ORY5uAhpMp__LOcWQGe-I75I0Dg0Lp1za8_i5XfQ

    And you should be good to go. A few things to keep in mind:

    1) If you install a new nightly, this fix will be gone, so you'd need to re-install it after every nightly. The plan is of course to have it merged in a few days, depending on the feedback I get on this.
    2) The cam will, just like in Touchwiz, decide itself if it's going to use Night shot mode or not. It does this based on the amount of light it sees in the front camera. So in normal light, it will shoot a normal photo. In low light it will shoot a low light mode photo
    3) In low light mode, the cam will actually shoot 6 photo's in a row, in a burst mode. It uses these 6 photo's to construct the final photo, which you will see in your album. So it's important to hold the camera still during this process !
    4) Just as in touchwiz, the low light mode only works on the main camera.
    5) The night shot mode currently ONLY works in the CM stock camera ! I will see if I can make it app independent, not sure yet ...

    I fixed all issue's I had, also the last issue's like photo orientation and it now also supports all sizes. But let me know how it works for you guys !

    Enjoy !

    Indeed, breakthrough !! @fattire and I have been working hard to get Android M up and just booted into the GUI ! Haven't even checked what does and what doesnt work, I'm sure a lot of stuff needs fixing but this is really nice progress indeed !
    37
    And another update on the low light photo mode: I just finished reverse engineering everything ! I understand exactly now what's happening. Basically it just puts the cam into the Low Light photo mode, where it shoots 4 pics in a burst mode. I already had that going. Then it uses a 3rd party lib by 'arcsoft' that contains methods to combine them into one picture.

    So, now I need to write all that myself and I'll need to go through it all one more time to take some more notes of all the pointers and objects it creates. But I'm 100% sure now I can get it going since I've seen it all now, there are no more possible 'hidden difficulties'. Just need some time to fix all this up myself and go through it all one more time, but I'm hoping I'll have it going now within a week. If everything goes right and I have some time, I might have it going around the weekend, we'll see :)
