CM13 ROM for Galaxy S3! [Android 6.0.1]


For those of you looking to upgrade to latest Android 6.0.1, we have some great news for you, CyanogenMod Team has released official nightlies for several models of the Galaxy S3 including GT-i9300, Verizon, and there are unofficial versions (that are just as good) for the GSM models (AT&T, T-Mobile, and Canadian).

The CM13 ROM will give you the latest Android 6.0.1 along with everything working out of the box including voice, data, bluetooth, camera (video recording is broken on Verizon but works on other models fine), etc…etc… Performance is excellent (super fast) and you will be able to experience the latest DOZE mode (that allows you to save battery when not using the phone) that comes default with Marshmallow.

    Poorly written article, it doesn’t come with the doze yet, plus 64+16 is equal to 80

      They are referring to usable memory 🙂 I am running the CM13 ROM on my S3 with a 128GB Samsung Evo+ Card as internal memory, gross memory of course is 144GB but the phone shows usable memory as 130GB. It works great.

      As Bob said in his 29 Dec and 2 Jan posts, it was SuperSU that was messing up the boot. After installing just the ROM and GAPPS, it worked fine. Even SuperSU v2.52, designed for Marshmallow, doesn’t work. And although you can set root privileges in Developer Options (which you can do in 12 as well (who knew?)), that doesn’t appear to be sufficient for Titanium Backup (TB would restore, but couldn’t back up). Also had crash issues with SnapChat, and was concerned that the generic i9300 CM13 on the CM nightlies page wouldn’t work for the AT&T phones, so, hi ho, hi ho, it’s back to 12 I go. It was nice to play with it for a few days, and I look forward to a maintained CM13 for d2att.

        Hey Rob, I ran into the same issues, I reinstalled again and it worked (if it were only that simple with CWM) use TWRP to install it’s MUCH EASIER. Once it’s installed don’t forget to go into Developer Options and enable root access. I think that’s what hung me up with CWM.
        Anyways, I’ve been running CM13 as my daily driver on my SGH-i747 for almost 2 weeks now, works good. Use TWRP, it’s way more reliable and with Advanced Boot enabled in developer options you can can go right to recovery mode when rebooting.
        Go to Settings, About phone, and tap on the Build section until it enables Developer Options.
        Giod luck

    Will there be a version for Sprint Galaxy S3?

  6. Bob says:

    I’m having trouble enabling my root access. I’ve enabled developer options and set root access to Apps and ADB, but SuperSu and Titanium Backup doesn’t want to work.

    • Bob says:

      So CM13 has built-in root like as shown in the video. Installing SuperSU messes up the root so I had to reinstall and enable root in the developer options again.

    I flashed my AT&T SGH-I747 and got it working. The only problem is when I’m using bluetooth in the car. The audio is extremely choppy when I use bluetooth audio and the phone crashes and restarts when I make/receive calls on bluetooth.

      Have two ATT S3 (i747), got one (let call it orig) from att with contract 3 years ago, second one (also att) from ebay about year ago.
      On orig one installed carbon rom about 1.5 years ago, all worked fine. Installed carbon rom on ebay one as soon as I got it – no issues either.
      Couple weeks ago Installed cm13 on ebay one without issues whatsoever. Good, few days later picked orig one, SIM card not recognized. Restored to backup (carbon) sim works. After a lot of reading, came to conclusion that issue is obsoleted drivers on orig one. I do not remember ever installing OTA on it, and after placing carbon on it, that would have not worked anyway. One from ebay must have been OTA updated by previous owner, so it had updated drivers (custom roms aparently do not touch that portion of the phone). Did not check all baseband versions at the time, but believe that was the case.
      Solution: Installed original rom (check un-rooting your phone to factory state on this site) which in my case put me back to android 4.1.1. Let it update OTA to 4.3, about 700MB. Baseband version now ends with letters JB. Copied CM13 and gapps onto phone, and then flashed phone with CWM (see instructions on this site). Before flasing with Odin, checked off reboot and, once green PASS sign showed, pulled out battery before phone reboot (apparently it overwrites stock recovery back if you let it reboot), put battery back and booted into CWM.
      Once in CWM, ‘clean’ install CM13, then gapps, reboot, skip wireless connection of first setup just in case, everything works now.
      No need to mention this is refined version what I believe to be correct. I have made million mistakes and re-flashed countless times, maybe some of those mistakes had some effect, can not really tell. One thing though, carbon rom backup did not work after restoring to factory state, on restore it would not boot. On another step CWM recovery would not load (gets stuck and reboots), fixed that by pulling out battery and placing back and than booting into it etc etc etc…
      All in all, business as usual. My experience is that it is fixable as long as you do not flash anything meant for other devices. Good Luck!
