Just leaving this here.
https://github.com/Stratosphere-Kernel/wt88047

The latest "release" is not up to date. Interested folk can fork and upstream to pirej's source and then hit compile. I used Linaro to compile my builds but theoretically any ARM64 toolchain should work.

Hi @pirej and friends, ever since I flashed this rom, my home and recent buttons malfunctioned. Changing roms didn't fix the problem. Any advice how to rescue my phone?

Hi, this rom is built using arm64 sources from Codeaurora, branch LA.BR.1.2.9_rb1.29 with some adjustments to fit our "little precious... "

Code:

#include <std_disclaimer.h> /* * Your warranty is now void. * * I am not responsible for bricked devices, dead SD cards, * thermonuclear war, or you getting fired because the alarm app failed. Please * do some research if you have any concerns about features included in this ROM * before flashing it! YOU are choosing to make these modifications, and if * you point the finger at me for messing up your device, I will laugh at you. */

INSTALLATION
- MAKE BACKUP of your working rom before flashing this one.
- Boot into recovery
- Wipe System, Data, Cache, Dalvik Cache
- Flash the zip
- Reboot your device
First boot takes some time. Wait patiently.

WORKING
- Wifi,
- Bluetooth,
- RIL (voicecall, sms, data),
- SDCard,
- audio / video
- FM radio
- Camera
- GPS
- VoLTE

NOT WORKING
~~- Camera~~
~~- GPS~~

DOWNLOADS

If you want root, flash
"phh's SuperUser"
OR
SuperSU
OR
MagiskSU

Gaaps are not included, open_gapps-arm64-7.1-pico works fine.

The ROM supports signature spoofing, so you can use microG as a "replacement" for gaaps.

I have other real "life bugs" to solve, and that doesn't leave me any space for this any more.
Im still using the Redmi2 daily with this caf rom, but im using it just as a smartphone, not a test device, i haven't even rebooted the phone for months
Its been a fun journey coming from kitkat, making roms and kernels without official kernel sources at all, and everything worked(more or less) at the end.
BIG thanks to all of the XDA members that supported my work and the development of Redmi 2 in general, and GIGANTIC thanks to balika011, the guy who put everything together to make the FIRST public kernel sources that worked for Redmi2, and everything after that was easy.
There were other big contributors to the development too, but i wanted to mention the one that everyone forgot about, and probably 80-90% of the redmi2 users don't know that HE was the one who made it possible, not some low lives like me, or some self proclaimed "developers".
Redmi 2 has proven to be a very potent device, very convenient for development, and i will buy Xiaomi phones because of that experience.

Thanks again, pirej.
