Build instructions

Update: as of 2016/01/03, everything needed is merged, so simply follow the official build guide.

If you don't want to or can't (ex. remote servers) use extract-files.sh, simply clone proprietary_vendor_samsung into vendor/samsung.

wow this is great @Ziyan truly appreciate your awesome work!
Testing it now.

It's actually running really really well! Posting this from the 1130 build now! One thing that did work on FML and just refuses to on cm12 is getting the APN to stick, it says "APN settings aren't available for this user" (which I think it also said in FML but still stuck after it was saved), otherwise everything else has been mentioned in the op as far as quirks are concerned

I'm getting much worse battery life than with the last CM11 nightly. Overnight battery drain was 3.7%/hour, compared to around 1%/hour with CM11. According to GSAM, the main issue was system(mediaserver) at about 94% of battery usage. No media was being served, so far as I can tell. EDIT: battery life often improves for me a day or two after installing a new generation, so I'll see if it gets better today.

I notice that the google bar at the top of the page always has: Say "OK Google." My Nexus 5 running stock doesn't have this.

It's also much laggier than CM11.

Video works with NuPlayer unchecked in Developer Options. Specifically, I could play video with MX player.

Possibly related to camera not working, the flashlight doesn't work. I only tried turning it on with quick settings.

No crashed so far and no app problems other than camera.

Tap and Go setup (against my N5), worked properly. It didn't work on FML.

I'm testing without a SIM at the moment, just wifi.

Thank you Ziyan

I had my SIM fried somehow after i flashed the rom yesterday, I had to replace the sim card today with a new one, the old one is toast.
It happened during "cellular network setup", it wanted my pin number, as soon as i entered it it was asking for my puk number.
Typed it in, things finished but without network connectivity, had the no sim card sign on the statusbar.
Could it be something connected to the rom or it was just my sim card time to go?

Cheers

Just want to say thanks!

Don't have enough posts to be allowed to post on the CM11 thread, so doing it here.

Ziyan,
Thank you so much for your work on this and I am looking forward to the first monthly CM12!

Try turning off ok google detection from the launcher settings - also, if you use the default launcher, set the app drawer animation to "none", because CM forgot to update that part of launcher to lollipop - they left in the animation from 4.4, so it's laggy and ugly. I just submitted the patch set to fix that, they merged it already so the next build will have this set by default.
Also, if you manage to break camera or video playback, I noticed it tends to leave the video processing part of the CPU active all the time until you reboot, so try that out too
As for the lag, it should improve over time.

There's no way a ROM could to that

 

[teikiatsu]

is the camera wb (white balance) fixed?

Same problem here with PUK.

you could collaborate with @MWisBest to solve the basic problems

They already collaborate I think

I rebooted and recharged about two hours ago and battery is draining at 1.7%/hour (including listening to music, not just on idle). While it's usually a mistake to rely on short time periods, the prior drain could well have been due to breaking camera and video playback. I'll continue to monitor.

I'm using the google now launcher and like ok google detection. If I get down to similar idle battery drain as on CM11, I'll leave detection on, otherwise I'll test with it off.

I'd hope lag would improve as we go beyond early testing

Thanks

EDIT: battery drain on idle is going down a bit, suggesting your diagnosis of broken video leaving the CPU active was correct.

For those who don't know, we are getting Lollipop on GN because of these 3 people: @Ziyan , @freshgiammi , and @MWisBest. Lollipop FML was only possible because of those 3 people. Same thing applies for CM 12. It's not like they were working separately. So all 3 are due equal credits for making it work for us.

of course thread subscribed and waiting for the amazing work I'm sure ziyan will do :fingers-crossed:

Same bug with PUK

Ok, I don't know which information matters but:
I'm in Germany.
Steps before flashing new ROM from the 30th:
-> wipe cache
-> wipe system
-> wipe dalvic
-> flash rom (everything from cwm)
While trying to flash gapps i got error code 6 (Which i found out later was a buggy version of CWM (6.0.4.7)) but I didn't care and rebooted.
Everything seemed to work, but a few seconds later he asked for the PIN (like always).
Typed PIN correctly, after the FIRST try, the phone asked for the PUK.
Now, after flashing a newer CWM and the most recent cm-11 nightly + gapps ... at least everything works again, except for the SIM cause i can't find my PUK ... well, gonna buy a new prepaid tomorrow. Still an interesting bug ... does anybody know how this could happen? Would be nice to use Lollipop, even if it's bugged as hell ^^

edit: Without SIM, the ROM looked awesome. I had no lag and any app worked. BUT the home button did not. ^^

 

[chilli_pepper]

Is this running the newer GPU drivers?

 

[AgentSmith]

Has anyone tried lollipop minimum gapps yet with these builds?
