See the 9-11-12 Cyanogenmod Announcement at bottom of post! There are now regular Nightlies you are used to and now the M-Series Roms, I will let the CM Team speak for it themselves as to what it is, see quote and link at bottom of post.
As of 8-18-12, the Verizon Galaxy S III, yes the one with the formerly locked bootloader that everyone loved to hate, has now been accepted into the Official CM10 Jelly Bean Nightly builds. Bookmark THIS PAGE to check for the latest nightlies. Many thanks to everyone involved in getting the d2vzw this far including you, African Canadian Sock Monkey!
Official Announcement from Cyanogenmod 8-18-12
Today we kick off the nightly builds of the CM10 JellyBean code branch, builds will show up later this evening.
CM9 nightly builds for devices that don't receive a CM10 nightly will continue (for the meantime) but we are changing the timing on them to be once a week instead (aka weeklies). This will allow a means for us to test bug fixes and the like as they get merged into the ICS branch - as stated before, the CM9 branch is in an otherwise perpetual code-freeze.
The devices receiving CM10 nightlies this evening include (but aren't limited to):
# The US SGS3 variants
# The Galaxy Nexus variants
# The Nexus S varaints
# The Nexus 7
# The Transformer and Transformer Prime
# The SGS1 variants (Vibrant, Captivate, International, and i9000b)
# The SGS2 i9100g
# P3 and P5 tablets
Other devices will join the roster as they become ready and gain their maintainers blessing for nightlies.
Edit d2vzw nightlies will require the insecure bootloader. See http://goo.gl/CST0K
I didn't see a thread for this so I figured I would go ahead and create this thread for the discussion and following of the d2vzw Official CM10 Jelly Bean Nightlies. Our maintainer cvpcs has stated that the initial official nightlies may not have all of the fixes such as MMS fix in them until those fixes are merged into the official tree.
YOU MUST BE ROOTED:
I recommend using the Casual app from Adam in THIS THREAD.
YOU MUST BE UNLOCKED:
As stated the official version of CM10 nightlies for d2vzw requires you be on an unlocked Verizon GSIII. As an alternative to the Casual method Adam posted up, you can now unlock your device using a simple one-click app made by fellow dev mmmeff called VZW GS3 EZ-Unlock on the play store.
YOU MUST BE RUNNING A CUSTOM RECOVERY:
Also see his EZ-Recovery for VZW Galaxy S3 app for the easiest way to load any custom recovery you want. Please note the Touch CWM 188.8.131.52 available in the app doesn't play nice with CM10. Don't use it. I personally recommend using the CWM (non-touch) versions such as 184.108.40.206. If you prefer 220.127.116.11 Touch and want to flash it using the EZ-Recovery app using the "custom" option, simply flash this file using the app.
If you would rather not use that app, see THIS THREAD for CWM 18.104.22.168 files and install instructions.
THIS THREAD. If you like using mmmeff's EZ-Recovery app and want to flash TWRP 22.214.171.124 using the custom option, use this file.
BECAUSE WE ARE NOW UNLOCKED, WE NO LONGER REQUIRE OR USE ANYTHING KEXEC
* In case anyone is still running CWM 126.96.36.199 from the kexec kernel days it is fine to use still. It functions as a standard custom recovery but had the additional ability to run kexec enabled kernels. So you can continue to use it or upgrade to another version. Because we are unlocked you are free to use any recovery now and Kexec is no longer applied.
So now all you need to do is root your phone, load up those two apps, load the recovery (i recommend the newest TWRP 188.8.131.52), unlock the device, and download and install the latest nightly in recovery.
GOOGLE APPS (including Play Store) ARE NOT INCLUDED IN OFFICIAL CM:
Make sure you also have a copy of the CWM flashable Google Apps on your ext sdcard which can be found HERE thanks to our friends at goo.im because CM doesn't come with Google Apps by default.
If you do a complete wipe and install an official CM10 build clean and you still have gapps remaining without having ever installed a gapps package, you likely didn't get a clean wipe. Recommend rebooting and wiping again and re-install.
WILL I LOSE MY IMEI IF I FLASH THIS?:
THIS THREAD for latest IMEI discussions and detailed methods for backup and restore.
CM OFFICIAL NIGHTLIES DO INCLUDE A KERNEL:
Flash, MMS, NFC or Native Tethering work on these builds?
Let's put it this way. They have all worked at some point or another. Then you have the fact that so many people posting here are contaminating the results with comments about unofficial builds and people that are flashing using different methods, etc......There's no good way for me to track and update this portion accurately. If you rely on any single feature to work properly, you are using the wrong ROM. Go back to stock. If you are flashing Nightlies of anykind you should expect things that have worked all along, some days will be broken. So the best thing to do is try it yourself and report here for others to see. These might be official nightlies but it's still very BETA and WIP (Work In Progress) and should be treated as such.
I can confirm personally as of the 8-20 build MMS is working and persistent after a reboot!
NFC fix found here.
WPA/WPA2 Native Tethering WORKS
You can flash the file in THIS POST to fix native tethering with WPA/WPA2 security intact.
Sideload the newest Adobe Flash app found in THIS THREAD to get Flash on Jelly Bean. Of course you must have "Unknown Sources" enabled in Settings->Security to sideload any apk
If things change, let me know via PM, I'll try to update the OP.
UNOFFICIAL ALPHA BUILD THREAD IS OVER HERE.
In that thread you can find discussion and info on the unofficial alpha builds by people such as cvpcs, invisiblek, dhacker and others who have been part of the efforts to get us to where we are today. Their contributions are invaluable. Those builds right now may actually run smoother and have less bugs because they are UNOFFICIAL which means they can do what's called "cherry picking" and include code that has not been committed into the OFFICIAL builds yet. The official build may or may not have all those features. They are sometimes different ROMs functionally.
Now that we have an Official Nightly build in order to not confuse people please take Alpha Unofficial talk to that thread. Please keep posts here on topic and relevant to the Official Nightly builds. Things that work on those doesn't work on these and vice-versa.
CHANGELOG IS HERE and UnOfficial CM10 Bugtracker is HERE
UPDATE, Official Announcement from Cyanogen Mod, M-Series Roms Announcement 9-11-12
Something we have learned over the past few months is that if you don’t release, someone else will do it for you. Since we are open-source, we absolutely encourage it! Unfortunately, the quality of unofficial builds can vary, and we are serious about quality. Of course nightlies are always available, but we realized that having something that is a bit more stable on a more frequent basis is important. Starting now, we are rolling out our M-Series releases. M-Series builds will be done at the beginning of every month. We did a soft freeze of the codebase for the last week, blocking new features in order to stabilize. Our plan is to continue this (assuming that the response is good) up until stable release, and onward.
We aren’t exactly sure what M stands for. “Monthly”, “milestone”, or perhaps “MINE ALL MINE!”. Whatever it is, I hope that we are meeting the needs of community.
M-Series builds will be available under the EXPERIMENTAL tag. The filename will include the date stamp as well as the M version. These builds should be stable enough for daily use, and we encourage feedback and bug reports.
Tonight’s M1 build is available for these devices:
Galaxy Nexus GSM (maguro)
Galaxy Nexus VZW (toro)
Galaxy Nexus Sprint (toroplus)
Galaxy S2 GT-I9100G (i9100g)
Galaxy S (galaxysmtd)
Galaxy S B (galaxysbmtd)
Galaxy S3 Sprint (d2spr)
Galaxy S3 VZW (d2vzw)
Galaxy S3 AT&T (d2att)
Galaxy S3 TMO (d2tmo)
Galaxy S3 US Cellular (d2usc)
Nexus S (crespo)
Nexus S 4G (crespo4g)
Galaxy Note AT&T (quincyatt)
Google Nexus 7 (grouper)
Sony Xperia Acro S (hikari)
Sony Xperia S (nozomi)
In standard CM style, we will continue to add devices as time goes on up until our stable release.
Head over to Get.CM to grab the latest build for your device. Installation instructions and other documentation can always be found at the CM Wiki and help is always close at hand over on our official forums.
If you need a more general "all things GSIII guide" to bail out of a problem, or to do other things that aren't necessarily CM10 specific, I highly recommend THIS THREAD
