The Background:
I got this phone as a replacement to Galaxy Grand and soon I realised it's not sufficient to be on the stock kernel for all obvious reasons.
I'm used to great kernels like Dorimanx on SII.
So I searched on the Lenovo and XDA forums and soon realised that Lenovo was releasing incomplete sources for their devices(Specially A6000). Soon they released LP build for A6000 along with complete kernel source. The LP source builds well but KK source was still incomplete. But the wait was over and they release complete source for Kitkat release.
I'm still using KK on this device because their LP builds are not yet mature and couple of features like Encryption are still missing on LP (I need them)
DISCLAIMER:
ONLY FOR KK 4.4.4 Stock ROM
I'm not responsible for bricked devices or flashing wrong version
You are using this kernel at your own responsibility
NO Lollipop Support, Don't ask for it



——— !!!!!!!! YOU HAVE BEEN WARNED !!!!!!!! ———

FEATURES:
This kernel include the following additional features:
* Built on Linaro 4.9.4, (Stock kernel is on 4.7)
* Cortex-A53 Optimizations
* Additional Governors, Alucard, Hyper, darkness, OnDemandPlus and others.


CREDITS:
Dorimanx (for all his kernel sources, SII, LG)
Alucard_24(for Alucard Governor)
Torvalds (Kernel 3.6.Y maintainer)
Stelistcristi (Contents of this post)
osm0sis (For Android Image Kitchen)
Kiran Anto (for his Razor kernel sources)

KERNEL SOURCE:
Source code of the kernel can be found here:
https://github.com/chhapil/Kernel-Lenovo-A6000-KK


TO Do List:
I'm planning to add following features, but NOT ETA
1. Create flashable zip instead of boot.img
2. Add SuperSU and busybox to the build
3. Add additional IO schedulers
4. Add Synapse Support
5. Overclocking
6. Other mods that I see fit


Steps:
1. adb reboot bootloader
2. For temporary flash, fastboot boot boot.img
3. For permanent flash, fastboot flash boot boot.img
4. The phone will reboot automatically.
5. The Stock Rom doesn't show Kernel version on about page, here is the command to verify the kernel.
PHP:
adb shell cat /proc/version
Linux version 3.10.28-Kernel-MoStock-V1.1-A6000+ ([email protected]) (gcc version 4.9.4 20150629 (prerelease) (crosstool-NG 1.20.0 - Linaro GCC 2015.06) ) #1 SMP PREEMPT Fri Nov 20 18:53:31 IST 2015

FAQs

1. Can I use it with MIUI ROM?
Honestly I don't know, people of reported that it works, better search the thread of relevant details

2. I bricked my phone!
Safest procedure to check whether your phone works with this kernel is not flash it in first attempt.
just put command "fastboot boot boot.img"
This temporarily boots phone with new kernel,
If phone fails to start with newer kernel it automatically falls back to older kernel.
If it works well, then you can permanently flash it with "fastboot flash boot boot.img"

3. My Wifi/FM not working
This is the issue with the kernel modules.
This issue has been laying around, here is the cause,
FM, Wifi drivers are loaded as modules by the kernel as per need. It has its own advantages in terms of kernel size and memory utilizations.
On stock ROM these modules are loaded from /system/lib/modules
My efforts had been till date to minimise the changes on the ROM to keep it working with existing modules. But it seems with optimizations and newer toolchains the hack wont work anymore and hence is FM crashes while loading the FM driver. (WLAN driver is still working though with the hack)

So I'm publishing the latest compiled modules. (Find them in attached zip) They would resolve this FM issue. Also the wifi modules

Here are the steps,
1. Download and extract the modules zip on your phone.
2. Backup existing radio-iris-transport.ko from /system/lib/modules
3. Copy and replace radio-iris-transport.ko from the modules folder in /system/lib/modules
4. Alternatively you can replace all the existing .ko files with the one i have provided. Make sure you backup them before replacing.
5. You can Use Es Explorer or ADB to follow these steps.
6. Set correct permissions 644 (either chmod 644 or ES Explorer-> file ->Properties->permissions)

Is anybody actually using the kernel?
There are no comments, nor i see any good traffic on the github downloads.

In case no response or activity, probably I'll stop posting the builds.
Let me know guys

Please don't stop making I will post your kernel in whatsapp

---------- Post added at 10:23 AM ---------- Previous post was at 10:20 AM ----------

Please post this on main thread of lenovo a6000

---------- Post added at 10:25 AM ---------- Previous post was at 10:23 AM ----------

WhatsApp? What's that for?
I have reported this thread to admin for not being visible in devices thread. It will be visible soon.
I can not make kernel for cm11. I'm not using cm11 and don't have to time to make flash and test on it.

'It supports fast charging upto 1380 mah and this kernel is suitable for miui 7.I experienced it in stock kitkat rom and a user posted ss of this kernel in Miui 7 as above.please mention it in your page or on github page so that users can attract with this incredible kernel made by you.!!

What is max charging current in stock lollipop kernel? I find charging to be slow. And when I checked it shows 600 mA while charging and thats a bit slow.

Thanks for creating this great custom kernel for our device.
your custom kernel works on MIUI 7. Great. It gives long battery life (about 25-30 hours on normal usage). Performance is good too.
Please add more custom governor and hotplug.
And please Lollipop build

Thanks

Can I install this kernel on CM11.??

I've tested on CM11. Yes you can use it on CM11 (but you must create your own boot.img file, using CM11 ramdisk and MoStock kernel). But I found one bug (for now), WiFi will stuck on turning on. I don't know about other bugs.
I hope chhapil can fix wifi bug on CM11.

This kernel works like a charm on MIUI 7. No bug

    FM & Other Modules

    Hi All,
    Here is the fix for FM crash issue.
    This issue has been laying around, here is the cause,
    FM, Wifi drivers are loaded as modules by the kernel as per need. It has its own advantages in terms of kernel size and memory utilizations.
    On stock ROM these modules are loaded from /system/lib/modules
    My efforts had been till date to minimise the changes on the ROM to keep it working with existing modules. But it seems with optimizations and newer toolchains the hack wont work anymore and hence is FM crashes while loading the FM driver. (WLAN driver is still working though with the hack)

    So I'm publishing the latest compiled modules. (Find them in attached zip) They would resolve this FM issue.

    Here are the steps,
    1. Download and extract the modules zip on your phone.
    2. Backup existing radio-iris-transport.ko from /system/lib/modules
    3. Copy and replace radio-iris-transport.ko from the modules folder in /system/lib/modules
    4. Alternatively you can replace all the existing .ko files with the one i have provided. Make sure you backup them before replacing.
    5. You can Use Es Explorer or ADB to follow these steps.
    6. Set correct permissions 644 (either chmod 644 or ES Explorer-> file ->Properties->permissions)

    I'm working on publishing latest WIFI driver module also. But it would take some time.
