DownloadAll Jenkins builds are testing builds, and as such, are likely to be extremely unstable or unusable.

This goes doubly for these kernels: You know the risks associated with overclocking, and, though stable,
there may be hiccups in the kernel.

Instructions

If you are completely new to flashing custom ROMs and have no idea how to begin, start by downloading a TWRP image for your device from the links above and flash it using the ODIN tool (see below).

You cannot flash a custom ROM over stock recovery, so downloading a custom recovery is the first thing you will need to do.

Installation via recovery (TWRP)

* Download a recent .tar file from the links above for your device.

* Reboot into recovery mode [Press Power+Volume Up+Home].

* Plug in your phone into your computer, extract the tar file and place the .img to a location on your Internal or External Storage on a device.

* Click Install on TWRP on your phone and locate the img file in the phone.

* Enjoy your kernel.

Installation via odin

* Download a recent .tar file from the links above for your device.

* Reboot into ODIN mode [Press Power+Volume Down+Home].

* Plug in your phone into your computer, and open the Odin application, and place the .tar file in the AP slot and flash it.

* Enjoy your kernel

FAQ

Q: Are you taking device requests?
A: If and only if the device is using an msm8916 chip, and you're willing to buy me/donate the device for testing, sure.

Q: But I don't have that kind of money! What else?
A: Alternatively, if you're skilled with Linux and adb, and have an unsupported device, if you're willing to work with me as a tester, that works as well.

Q: Are you accepting feature requests?
A: Unless you're willing to implement it yourself, no.

Q: Can you make XXX ROM as well as LOS?
A: Unless more people donate, no. I simply don't have the time to maintain more than LOS nor money to hold that many ROMs on my already (tiny) struggling server.

Q: Can I throw money at you?
A: Most certainly. Donations are always welcome.

You want to help?

• We need hardware power to get the builds done.
  If you want to help us go faster, send a PM to @kentone or
  @vince2678. Your computer will act as a client for our jenkins server.
  
• In a perfect world, that would be all, but unfortunately no. We need money to keep the server running and keep bringing these ROMs.
  
• As always, logcat any problem you find.

PLEASE, don't PM @vince2678, as he's busy right now, and your questions can be not answered. PM @kentone instead, write here on the post, or on the telegram group, your questions will be responded as soon as we can Understand that we have family, studies and jobs aside of this project. Thanks for your understanding

[B][U]29/08/2017[/U][/B]

* [B][[COLOR="Red"]NOTE[/COLOR]][/B] [B] Shifted to using a kernel driver for disabling touch devices
  when the screen is off instead of a user service for that. [/B]
  
* [B][[COLOR="Red"]NOTE[/COLOR]][/B] [B] Updated kernel to the latest upstream AOSP and
  CAF tags. There should be a noticeable performance boost. [/B]
  
* [B][[COLOR="Red"]NOTE[/COLOR]][/B] [B] Disabled cpusets support, which was slowing
  down the system performance. [/B]
  
* [B][[COLOR="Red"]FIX[/COLOR]][/B] [B] Data should be working fully on all devices. [/B]

[B][U]08/06/2017[/U][/B]

   Updated F2FS code from upstream kernel sources and enabled
   security extended attribute support (for SElinux) to fix
   android support.[/B]

[B][U]15/05/2017[/U][/B]
* [B][[COLOR="Red"]NOTE[/COLOR]][/B] [B] Added support for SM-G530M (fortunalteub)[/B]
* [B][[COLOR="Red"]FIX[/COLOR]][/B][B] The sleep issue should be fixed in the
  latest build. This was due to the failure to set a
  critical kernel variable at boot because the kernel init
  system was not interpreting a boot command line variable correctly.[/B]
* [B][[COLOR="Red"]FIX[/COLOR]][/B] [B] F2FS is enabled in-kernel, so F2FS filesystem
  mounting and formatting should be working fully.[/B]

[B][U]05/05/2017[/U][/B]
* [B][[COLOR="Red"]NOTE[/COLOR]][/B][B] Wifi driver is being built as a module for now,
  transitioning to a new kernel somehow broke the ability
  to build it into the kernel binary.[/B]
* [B][[COLOR="Red"]NOTE[/COLOR]][/B][B] Transitioned to a new kernel based on T560NU and
  J500H MM kernel sources (J500HXXU2BPJ9 and T560NUUES1BPL1). [/B]  
* [B][[COLOR="Red"]NOTE[/COLOR]][/B][B] Updated kernel and wifi driver to LA.BR.1.2.9_rb1.16[/B]

[B][U]14/04/2017[/U][/B]
* [B] [ [COLOR="Red"]ALL[/COLOR] ][/B] [B] Created DevDB project [/B]

* [B][[COLOR="Red"]NOTE[/COLOR]][/B][B] Wifi driver is now built into the kernel. Should
(slightly) improve speed of enabling/disabling wifi. [/B]
* [B][[COLOR="Red"]NOTE[/COLOR]][/B][B] Updated kernel and wifi driver to LA.BR.1.2.9_rb1.14[/B]
* [B][[COLOR="Red"]NOTE[/COLOR]][/B][B] Builds now use sdcardfs from Google. This should
 result in faster file operations on the sdcard overall
 compared to using FUSE as an overlay.[/B]

Great work Vince! Gonna try it soon nd will let you know.

 

[abooooood]

Maybe stupid question
But if CPU overclocked to 1612
It won't be damaged or something
I mean why Samsung didn't make GP stock CPU like this ??

Sorry if its stupid question
But if it won't damage the phone CPU
The performance will increased as hell

All processors are put limits, snapdragon 410 goes up to 2.1ghz, but it's like asking the mobile phone does not last a month, Do you use xxu or xcu?

 

[vince2678]

No boot in xcu

Got stuck in the samsung logo

Tested in aex 4.0

Sorry, my fault. Meant to write 'XXU' instead of 'XCU'.

Will make a build for that soon, keep wacthing the thread.

I've been using it myself for about a month with no adverse effects.

I chose 1612Mhz because it's fast enough without risking instability. At higher frequencies the memory might not be able to keep up with the cpu/gpu clock, so I have not gone higher than that (though they may work).

OK thanks for reply
I will keep watching thread for xcu ?

What are the bugs of that ROM bro ?

 

[AlHezZz]

No boot un xxu LOS 14.1
You only see SAMSUNG GALAXY GRAND PRIME.
I USE TRANSLATOR

I Test 13.0

 

[AhMaD eLMoMaNi]

when will you make XCU build ?
@_@

+1
On 2GB devices it could've been useful but battery consuming as well. Whats the minimum frequency you've set? I suggest you to set to 200Mhz, that will greatly save the battery.

OK thanks for reply
I will keep watching thread for xcu ?

when will you make XCU build ?
@_@

You should wait but please ETA is not allowed.
He'll soon make a build for xcu as well but till then Keep Calm nd Enjoy!

The minimum was already at 200MHz, but thanks for the insight anyways .

 

[redfeast]

he already mentioned for LOS so it may not work for aex

 

[L3R0N]

G530T on LOS 13. All seems fine here and over clock is functional. Thanks Vince.

 

[AhMaD eLMoMaNi]

At first thanks alot for this great work ,this OC is very safe and SUPERFAST .but Unfortunately Wifi isn't working on 530H (XCU) LOS 14.1 .This is the Logcat that I've got

I've a few skills on Linux system I can help you to test things if you want.​

SM-G530H (XXU) wifi not working

 

[DanteDFG]

Wifi also isn't working for me on the G530T with the 4/7 build of cm13, but when i use the nightly for 4/16 it works, but then I get no outgoing call audio, but then again I was still getting no outgoing call audio without using the kernel on that build

The fast charging is not something that has an exposed sysfs interface so it's not configurable.

SM-G530H (XXU) wifi not working

As for the wifi, it has to do with the fact that your devices use a wifi module instead of one built into the kernel. I'll work on a flashable fix for this later this week.

Wifi also isn't working for me on the G530T with the 4/7 build of cm13, but when i use the nightly for 4/16 it works, but then I get no outgoing call audio, but then again I was still getting no outgoing call audio without using the kernel on that build

Yes, we switched to using a built in wifi module on the roms i make, so an upgrade is necessary to use the kernel.

 

[DanteDFG]

Yes, we switched to using a built in wifi module on the roms i make, so an upgrade is necessary to use the kernel.

So since we'd have to upgrade to use it, and that 4/16 one was a test build and not nightly is it safe to assume the next LO13 nightly will have the in-call audio fixed? I can't hear anything not even if it's ringing the phone unless i switch speaker phone on and off. Or the gprimelte not recieving any more LOS13 builds? I see only LOS14 avail now for it but it has no themes and doesn't update/refresh the screen when watching videos on the browser unless i start dragging my finger across the screen while it loads...
