CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.
All the source code for CyanogenMod is available in the CyanogenMod Github repo. And if you would like to contribute to CyanogenMod, please visit our Gerrit Code Review. Your changelog is whatever was merged into gerrit.

Hi @dianlujitao ,
I`m going to test your CM build as far as just NFC not working .. I don't use NFC anyway ..
I`ve got just one question. What kind of GAPPS to download for this build .. ARM or ARM64?

---

Already installed and testing.. Until now:
1. WiFi coverage is very weak .. Even very close to the router signal is not 100% .. over 6-7 meters and its half already (with stock based is full). ..
2. GPS works .. find and fix satellites ..
3. Compass still not working 100%. After every reboot needs complex and long calibration .. Works with some apps like Google Maps .. but don't work with other like GPS Status and Toolbox.. So not fixed properly yet..
4. Heating is not like in previous builds for now .. Its not like B266 javix .. but its kind of optimized ..
5. Mobile Data, WiFi on/of .. seem like is fixed .. There is not sim disconnect for now ..
6. CPU states issue . .still not fixed .. 200-400-533 states are not used ..
7. Sound is not crackling like previous builds .. but its low, recording too. Very very low sound when talking too ..
8. Auto Rotate is working .. Camera can't shoot videos in Portrait ..
The ROM itself is very very fast and fluid .. Cant say anything for now about multitasking .. but seems fine at this moment.. Need time to see battery life too..
In other side .. I don't know is it about my device or GAPPS/ROM itself, but a lot of apps from PlayStore can't be installed (Error 403).
So .. I`m back to B266 Stock for now .. waiting someone else to report when everything is fine .. because I use the device daily, but its not possible with CM12.1 builds for now ..
Thanks for the hard work .. again .. "Keep Walking" .. :fingers-crossed:

Hi. i am testing your rom.
i do confirm the problem about weak wifi.
Camera can't shoot videos in Portrait + it seems that things are distorted...
no possibility to set battery led color or notification led colors?
rom is very fast and fluide, that is good surprise...
actualy compiling with you cherry device tree give that kind of errors related to sensors folder...
http://pastebin.com/MV9VvGM8
but i look in your device tree on github there is no sensors folder... ???
https://github.com/dianlujitao/android_device_huawei_cherry/tree/cm-12.1
i checked and there is a sensors folder in the zip i downloaded from github...

I use prebuilt sensor hal from kitkat, or auto rotation can't work
I'll switch to surdupetru's wifi config to fix the leak wifi signal.
Another important thing I'd like to say,
@surdu_petru is using stock kitkat ril blobs, but data network can't start with them on a dual-sim device, e.g, my c8817d, so I use ril and qmi blobs from rendang, so issue comes. Many people they can't disconnect a call. Althrough rendang's blobs works well on my c8817d, some c8817d users told me they can't disconnect a call, it's very strange.
But some honor 4x users provide solution: Install official lolipop release, then wipe and install cm, the issue above got solved.
So I guess some kinds of baseband aren't compatible with rendang's ril blobs. My c8817d uses a very old baseband from emui2.3.
If anyone use my cm and got the above issue, there are 3 possible solution:
1. For those who have an official lolipop release, install it before install cm.
2. For those who don't, try to flash a old emui2.3 release instead of emui3.0, maybe you're lucky.
3. Use surdu_petru's release, it works well with single-sim devices

thank you sir for yours answers. i think that testin surdu petru or your work is quite interesting, and it might help to pick up the best from both of you and your work in the benefit of g620s and others device users...

Come on .. give me some advice
After I installed this ROM, now cant install any other or restore my backup ... TWRP report that the ROM is Installed or Restored sucessfully, but as I said ... when I reboot system .. it brings me back to TWRP .. all the time ..
PS: I found the way to install ROM with DLOAD folder on SD and Stock Recovery .. But I`m still confused what this ROM did ..

cpu min frequency locked at 800mhz, it isn't a bug.
See line 529 at https://www.codeaurora.org/cgit/qui...c/init.qcom.post_boot.sh?h=LA.BR.1.2.4_rb1.17
I'm just do in Qualcomm's way.

@dianlujitao would it be ok to make an ORG on github, so we can build roms from there ?
It's kinda a pain to jump from your git to surdus and to check CM and others for possible fixes.

i had same problem a few days ago, here is what i did... i restored backup of stock rom , then i flashed in fastboot mode stock recovery and all went fine...

I tried your Rom. Thanks for the wonderful job. As you said, I am also unable to disconnect a call. Please fix the issue. Most of the other things are working fine or adjustable.

In fact I don't own a g620s, I only have a c8817d, so it's better for you to use surdu's code

Hello, it might be better but how can i know that camera is opening so slowly at first boot with surdu petru device tree, 15 secondes if we don't use your device tree or rom? camera is opening in about 4 or 5 secondes...
we have to concentrate good points from one or the other dev . like first boot from your rom is really faster than surdu cm...( i think because of some defconfig tweaks) boot.img is more little also.....but i think that things will be soon better as newer devs are coming on that device...

Thanks. Downloaded and flashed. Only one problem. The call is not hanging up after disconnecting. A reboot is required each time to call another number or receive a call. Please fix it.

Currently I've no idea, it works well on some devices, and can't disconnect a call on others.
If your device have a official lolipop, install it and it gets solved.
If someday I get a common solution I'll let you know
