Hi, i have a ZTE Device v8200+ (Qualcomm msm8625, 512Mb Ram, 4",8mpx Main camera, 0.3 front camera android 4.0.4, Kernel version 3.0.21) (released in Venezuela)......
I wants to know if i can port a cyanogenmod rom or another rom (JB, KK) with my stock kernel (3.0.21)...Can i?
Hi Rvrjei,
Yes you can use a prebuilt stock kernel with some modifications to run CM on your device.
I've done a quick search on Github for your chipset and found quite a few hits, check it out!
Here are a few links to start building Cyanogenmod and setting up the device tree:

Elephone give money if you want work on GPL public release android for recent MTK soc

Hi !
Elephone want help of developpers, for working on android source code for recents MTK socs, because Mediatek source isn't open to the public, and Elephone want port Android 5.1 on them devices (and CyanogenMod, Miui...), and release the source code for the public.
Elephone said:
Glad to know Android 5.1 is released. We'd like our customers to get the lastest update on their phones. However, we understand that there're a few developers working on MTK devices because the source isn't open to the public. It's tough to work it out without the source code.
So we want some of the best developers to help us out, and the payment will be substaintial and favorable.
We need Android 5.1 ROM for the following Soc:
MTK 6582
MTK 6592
MTK 6732
MTK 6735
MTK 6752
MTK 6753
MTK 6795
If you dare to accept the challenge, please tell me your experience and send me the works you've done before. Email: [email protected] or send me PM.
If you don't know ROM development, you could still help us spread the message in the Android developer forums, so that you may experience Android 5.1 ASAP.

Very good news for us, and users of MTK socs on smartphones !

[Completed] Creating a kernel source for Karbonn Titanium S5 Plus (MT6582)

I, on behalf of the owners of the Karbonn Titanium S5 Plus device, based on the Mediatek MT6582 chipset, need some help in building a kernel source (not a kernel from source) for this device. I have a few fully working custom ROMs, a Github Account, some forked repositories of other devices having the same chipset but minorly-different hardware, and some time. What do I have to do to get to building a kernel source for this device?
It is a dual-sim device, based on the Mediatek MT6582 SoC, having a prebuilt kernel version 3.4.5, with no kernel sources even for its clone, running Android Jelly Bean 4.2.2 . @superdragonpt had created some new kernels for some devices(eg. the Wiko Darkmoon, MT6582, he created a new kernel source and a new kernel) having no previous kernel sources, how can I do the same for my device?
The Android One devices (Indian) are based on the same chipset, and have the same features. But, the difference is that they have a smaller 5MP rear camera and a locked bootloader, while ours has a 8MP rear camera and an unlocked bootloader. Can their sources be used for my device?
Also, after creating a Kernel source, how can I create an AOSP source for this device? Please help me out with this.
Hi there,
All things about your device is in this thread:
[ROMs and Recoveries] Karbonn Titanium S5 Plus/ S5 + - All Things And Dev.
Take a close look there and see if you find an answer there.
Good luck
I know, I started that thread.
It contains many Roms for my device, but there are no updates for them because it does not have a kernel source. There are no new kernels for the device because a kernel source was not released by the company. So, I asked it here.
I forked the kernel source from another device having the same soc, but I wanted to know how to create one specifically for my device.
One more thing. How do you build a kernel from a kernel source? Please help me out. Thanks in advance.
You can learn more about kernel development here:

I suggest reading a couple of the relevant kernel tutorials found here: http://forum.xda-developers.com/chef-central/android
Good luck

How Can I port Qualcomm Kernel Sources from another Device?

Hello ,
I'm trying to port kernel sources to a Coolpad Note 6 device. The device sources are completely closed source and the manufacturer is chineese, and probably won't release any sources in future.
I followed through @ataberkozen's tutorial here on how to port qcom kernel sources. But I'm stuck at identifying hardware, and finding drivers for my device. The compiling the kernel section also seems incomplete.
Can someone please help me / guide me in the right path to port a kernel to my device?
Code:
Device Info:
codename: clover
manufacturer: coolpad
device_name: Coolpad Note 6 (clover)
chipset: Qualcom Snapdragon 435
soc: msm8940
gpu: Adreno 505
arch: arm64
