[Verizon Samsung Galaxy S III] Stealth111:
CyanogenMod and D2VZW: Marshmallow Love!

To Make this easy, I am going to copy a bit of the common sense information Master Cylinder put up for the release of Lollipop, same basics apply here!

Huge thanks to Invisiblek for making these builds for us!

Thanks to Master Cylinder for all the super useful information!

De-unified Marshmallow builds for the Galaxy S3 line. This is for the Verizon variant (SCH-I535) only

CyanogenMod is a free, community built, aftermarket firmware distribution of Android 6.0 which is designed to increase performance and reliability over stock Android for your device.

Notes:

Please Use Firmware: VRBMF1

and

Modem/Baseband Version: NE1 (Also, see "Notes - Possible Bugs" section below)

(EDIT: The following statement might not be true. It happened to one user. Unsure about circumstances...)If you have recently downgraded firmware from 4.3 to 4.1.2, DO NOT flash the MF1 firmware. You'll brick your device!

If you know you never took the 4.3 OTA, then you can flash the firmware and modem to your hearts content.

CWM Recovery addicts: Please seriously consider giving up CWM and come on board with what works for sure with 5.1.x and up, TWRP. Problems have been coming up with CWM users so if you have one, that's were to start. Hopefully there's a 12-step program somewhere for y'all :)

Google apps addon:

Open GApps opengapps.org They have many options for you to choose from based on your needs. Updated daily.

>>>WARNING!!<<< The first time one installs Open GApps, you have to do it with a ROM update (or reinstall current ROM) AND manually wipe the system partition first. Then install the ROM and the GApps normally, then wipe Dalvik and Cache. After that, you can flash them anytime. (More info on Website.) ALSO, for now, don't install Webview as it might not work. There is an "Android System Webview" in the Play Store that will work.

I personally don't use GApps on my Daily Driver, I have a second S3 on Wi-Fi only that I put GApps on, and I use it to basically keep all my apk files up to date. When they get updated, I move the updated apk to my main phone! :)

I went to opengapps.org, went to Platform: ARM, then to Android: 6.0, and then to Variant: pico. Invisiblek made sure he warned me to do a clean install of the ROM, then Immediately flash the GApps package, then Wipe Dalvik and Cache, then boot. He said NOT to try to install ROM, then add GApps later otherwise bad things can happen! Obviously pick the flavor of GApps that suits your needs!

This page will be a work in progress, so please don't yell if something is missing. I just got the OK to share this with others and wanted to get it out there for you to enjoy. I have been playing with it for the last 24 hours and it is ROCK SOLID in my opinion. I haven't found any issues yet! Daily Driver for me for certain. If you have issues, please post them for discussion below!

BUGS:

Need to possibly load a different File Explorer to access SD Card (DoctorImpossible)

Access to camera is not functioning correctly (DoctorImpossible) *EDIT 11-23 build camera works, camcorder fix coming next build! :)

Outgoing text messages show "not sent", but actually send fine. (Stealth111)

Incoming phone calls do not show caller information (Stealth111)

**When you get your ROM installed and up and running, please be kind and put a small post with information about your install so we can get as much info gathered as possible. (ROM build you installed, Recovery type/version, Clean install, or Dirty (and if dirty, over what version did you flash), what GApps package you installed(exact one please) as well as when you installed it (if on same initial install as ROM, or differently). And lastly maybe the firmware/modem combo you are running. Thanks!

***IMPORTANT INFORMATION*** If you are going to flash to cm-13.0-20151121-UNOFFICIAL-d2vzw or later build, there have been some database changes. InvisibleK has provided a flashable zip file to accommodate nuking your old telephony and settings databases. Nandroid or backup files as needed if you want, as I seem to remember doing this with CM before, and clearing the database wiped texts and call logs I believe. This only needs to be done 1 time, the first time you flash any build from 11-21 on. After you have done this once, you are good to go moving forward, you will be upgraded to the new databases. If you do not flash the "Nuke_It" zip file, you will get phone FC's and a "No SIM Card" error message. So whether upgrading, dirty flashing or whatever, reboot into recovery, flash the ROM, and BEFORE you boot, flash the following zip!

Nuke IT Database Wiper

Profit! :)

Enjoy!
