[CM12][5.0.2][Unofficial][Dior][Stable] Optimized CM 12 for QCOM Redmi Note 4G - Redmi Note Android Development

Optimized CyanogenMod 12 Android 5.0.2 Lollipop for the Redmi Note 4G(QCOM) brought to you by haoyangw
NOTE: This is for the QCOM variant of the Redmi Note, otherwise known as Redmi Note 4G, and NOT the MTK variant of the Redmi Note. In short, this ROM will NOT work on the MTK variant of Redmi Note 4G
NOTE: GApps is NOT provided, use any GApps package you can find. I would recommend Open GApps for Lollipop(link below).​

The battery life so far on this ROM is amazing! It doesn't face any kind of drain issues so far, except maybe for the infamous Google Play Services wakelocks. To quote:

Reporting bugs
If you have found a bug, make sure you fill up a form here: Google Form: Bug reporting This allows me to easily track all bugs reported without scanning the whole thread. Do make SURE that you fill in a VERY detailed description! And don't forget logs! For a tutorial on how to get logs, here you go! Log tutorial Of course, feel free to still report bugs here as I will be monitoring this thread But you MUST fill up a form, reporting on XDA is optional
Sources
Manifest
For those who would like a shortcut to sync all the neccessary repos to build stable cm12, just download/copy the contents of this file into .repo/local_manifest: Local manifest xml and the next time you repo sync everything will be there Then just 'lunch cm_dior-userdebug' and 'make -j4 otapackage'
Manually
I've finally given up making my own trees and fixing the annoying bugs in Xiaomi's kernel sources, so here are all the working tree/sources brought to you by our awesome devs! I take no credit for this! GO AND THANK THEM!
Edit: I've made some minor updates and fixes to the trees, but still credit goes to them!
Updated trees(updated by me but originally created by the following devs)
Device tree
Kernel source
Vendor tree(a.k.a. prebuilt/proprietary blobs tree)
Original trees:
@Silesh.Nair's device tree
@Silesh.Nair's vendor tree
@audahadi's kernel source
@stane1983's kernel source
I've uploaded the device tree I used to compile twrp to my device tree above, the branch name is 'twrp'. It's based on syhost's outdated twrp device tree, with problematic flags removed to fix bugs and also translated back into english, so there you go!
NOTE: Currently this device tree is ONLY for compiling CM12, you can face all kinds of build errors if you compile CM11 with it. For example, you will not be able to compile sepolicy in the device tree. You have been warned. Have fun building

Version Number explanation
There will be 4 naming conventions for builds, namely Alpha, Beta, Release Candidate and Stable.
Alpha - Build is NOT tested and may not boot
Beta - Build has been tested and boots up, but there are many device-related issues and bugs
Release Candidate, or RC - Build has been tested and device-related issues and most bugs are fixed
Stable - No more than 3 minor bugs and no performance or battery drain issues(caused by ROM on my side)

---

I wouldn't mind being a tester! I'm installing now and I'll see how it works.

---

---

It's stuck on the MI boot screen.

Hi, can you send me a logcat please? Or install LiveBoot by ChainFire through recovery and post all the errors you see printed. Thanks a lot! Sorry if the ROM doesn't boot

---

Good to see someone is working on CM12 for our phone. I tried CM12 syhost version and it's awesome but camera doesn't work and I need it. If you manage to get camera to work that would be awesome.

---

Thanks for your work. You may want to check the source code for the official cm12 version of the htc desire 816. It has the same gpu/cpu combination so there must be some similarities.

What is the point of this thread when the rom doesn't even boot

The point is to encourage someone to work on device. Right now it gathers little to no interest at all.

Point is to give support to developer, or this thread will die. I think u shouldn't be on this forum, so ungrateful

Yeah I thought of that, I copied some bits from the desire 816 device tree for Redmi Note 4G. I've tried building recovery with my sources and device tree and the recovery works perfectly, so I think it must be something in the ROM that is the problem. I'll need a logcat for tracking the malfunctioning part.

Thanks a lot! Hope I can get this ROM working soon, then our beloved device will get Lollipop sweetness.
