Mtk - Xiaomi Redmi Note 4 Questions & Answers

Why there are almost no custom roms for the MTK version, if it is the faster variant? For example, Resurrection Remix is a nice rom, but it is not available for the MTK variant. Why does everyone develop roms for the slower device?

Because MediaTek don't release kernel sources meaning development for the device is next to impossible.

[Q] Support for MediaTek devices??mtk6589...

let me start by saying that MTK devices have the least custom roms compared to other chipsets..even cyanogenmod is still not available for them except some unstable ports here and there..i think it is a kernel issue but am not a developer so my question is simple...Will there be support for Mediatek devices like the new quad core mtk6589 that is almost as powerful as the tegra 3..

Why Xiaomi Redmi Note 3 (Mediatek) is neglected?

While Snapdragon has CM14, Mediatek has only CM12.1. Why Redmi Note 3 (Mediatek) is left behind?
Well, MediaTek is known of very bad in terms of custom developing. They just rarely releases source code.
So Xiaomi also didn't release source code for hennessy yet. And I'm 100% sure they won't do it. Without that it's hard to make stable custom ROM, because devs can't build custom kernel.
Also there are many more people who have SD than MTK and more people=better community=more custom developing
as said by kubap, Mediatek and Nvidia devices (except that nexus 7) won't get their source code released so developers can't build any stable ROM from source, that's why you get ported or no roms.
And MTK Redmis are banned in India right now. Whole India has only Snapdragon RN3. Snapdragon edition is the most popular all over the world. So the developers are mainly from China.

Custom roms for Redmi Note 2

Hello,i noticed that there are very little amount of custom roms for Redmi Note 2 and no official support from any custom rom developer. Is there any specific reason and is it really hard to develop rom for this phone? Thanks for your answers!
Because Xiaomi doesn't provide Android update
Or kernel source for mtk devices currently
This is because Xiaomi (mostly redmi series phone)
Use a lot of clone/fake chips and parts on non-important parts on the phone.
Even mediatek released 6.0 source already,
The clone/fake chips doesn't have new driver And cannot pass Google CTS for Android update
This is why letv 1s can update and Redmi Note 2 currently not. About kernel source, mediatek release their source since 67xx series. But still need drivers for working. Unlike good chips, clone/fake chips only have one version of Proprietary driver and not update. So those drivers cannot patched into new kernel. We need to reserve engineering those driver binary and patch them. This is difficult.
Nofearnohappy do this already but it is incomplete
it is true?can you prove it?

How to upgrade device tre from kitkat to lolipop and so on..?

I have a Lenovo s820 which is a quad core processor based on mtk 6589. Lenovo provided Open Source Code for Kitkat on their website but i would like to update it to lollipop or maybe further. I previously owned a MI4I(Ferrari) which originally had lollipop but the developers were able to modify the device tree to support nougat and now even Oreo. If anyone of you'll could provide the steps or resources to do so i would be grateful.
Looking forward to expert opinion on this thread.
The broken is the chip set. They never release the source code for their kernel changes. This is why you don't see alot of development for those chips.

Why isn't there any custom roms or mods for Infinix zero 3 ?

I have Infinix zero 3 x552 device (mt6795 ARM Cortex-A53) , i want to know why can't i find any mods or custom roms for it ?
this device has only marshmallow update and doesn't have any custom roms , what is the obstacles that developers are facing to make android higher than marshmallow works on zero 3 ? i just think it's powerful device to get latest android or at least higher than 6.0 , unfortunately i don't have much skills to build Android AOSP to be working for my device or port OS from other device to zero 3.
Because Infinix didn't release the source code for the kernel.
