For this week’s Galaxy S3 ROM of the week, check out Vanir ROM with Android 4.3.1, available for AT&T, T-Mobile, Sprint, Verizon, GT-i9300, and GT-i9305 Galaxy S3s.

Vanir ROM is an AOSP ROM (What is AOSP?) with the latest Android 4.3.1. Did we say 4.3.1?

Yes, Vanir ROM is one of the only custom ROMs currently available with Android 4.3.1, which was pushed out to Nexus 7 LTE owners couple days ago but luckily, Vanir ROM developers have ported to the Galaxy S3.

What can you expect with Android 4.3.1? Well, not much as far as visually but there are some subtle performance improvements and you will find some easter eggs in certain places. We ask you to find some of those and see if you can identify any new features on Android 4.3.1 previously not on Android 4.3.

    I was gonna try this on my Verizon GS3 but I might hold off. Too many people are saying that their phones aren’t booting up/getting hot/no data/cant make calls…etc….If you can confirm its running perfectly on the Verizon phone I might download this and give it a try. Not being able to boot the phone up and get back to stock or whatever scares the crap outta me.

    • Max says:

      Yes working fine on my Verizon S3.

    • dropvisor says:

      Funny thing happened when I flashed this ROM…after I flashed, it wouldn’t connect to data. I checked my imei # & it said unknown. I flashed back to illusion 4.2.2. & my numbers were back again. Doesn’t make sense to me but I’m still learning about this stuff. needless to say I considered it a get out of jail free card and started looking ALOT more seriously at backing up my IMEI number.

    • Eren says:

      VZW GS3 here.. working fine for me.. maybe a little buggy but nothing serious

  2. Sienna Berton says:

    I’ve always had this question but to date no one seems to have an answer. I own a T-Mobile Galaxy S3 LTE phone, which I’ve heard is really a modified AT&T model. Are the AT&T ROMs compatible with the T-Mobile S3 LTE phones? Thanks in advance for answering!

    • Max says:

      Since ATT ROMs are compatible with Tmo, it should be fine, the only difference is modem and these ROMs don’t flash modems.

  3. Sochai says:

    Interested with this custom rom.But before install it i just want to know.I will had “Not Registered On Network” again?

    Hi Max..please let us know this custom rom come with new or old modem firmware for GT-i9300?


    • Max says:

      That may happen regardless of ROM, I am not sure why it happens but sometimes it does. For me, that’s more like 1 out of 100 flashes but you can always fix it by flashing a stock ROM then try another ROM.

      • Sochai says:

        If flashed custom rom it should be fine.No problem with the network.This issue will happen after unrooted (flashed) stock firmware.It automatically change the imei number.I try to google if someone had post the modem firmware but didn’t found.

        Any idea Max?

        I have install custom roms many times using your post here.But i had the network problem when i unrooted my phone.The rom backup no more use if this problem happened.I tried to restore rom backup also same result.Installed stock rom (latest & old firmware) and installed another custom roms also no point coz i had the same result.Now i don’t know what to do.Hope someone can help me here.

  4. JESSE says:

    Was digging until I wanted to back up using TWRP and couldn’t…then upon crashing… Bootloop…. Lol so went back SLIMROM 4.3…. Solid like Liquid Smooth 4.3

  5. turnbasenerd says:

    This rom’s a bit buggy (for me ). I had to flash a few times to get it to fully connect to wifi. Then the annoying errors (re flash). Eh, it happens. But currently player pro won’t play. Pandora is on the fritz. Pandora just keeps skipping to the next song until all the skips are used. Then it wont play. Iv’e re flashed a few times. Using a Sprint model. Ill Try a few more times.

  6. Randy says:

    • Sochai says:

      Hi Randy…thanks for your help.It worked for me.I got back my imei number & network connection.

      Now i want to try Vanir rom.Can use Siyah Kernel with this rom?Which version i need to flash?

      Thank you very much…

      • Randy says:

        I don’t think it would work. Just install it with it’s the kernel the rom have.

      • tony says:

        You should try carbon rom, instead…It’s much more stable than Vanir

  7. Steven says:

    Do screenshots not work on this ROM? Flawless otherwise so far

  8. fred says:

    why for the last two roms does the keyboard timeout when loaded

  9. fred says:

    why does the keyboard timeout on each of the last two now roms? your site has really gone downhill since its inception
    user from the start

  10. JESSE says:

    Don’t listen to “people” Max… Your site kicks ass… You do a lot for us peeps and all you ask for is for comments… (Hopefully positive ones) … If a ROM is buggy or whatnot…. Do your OWN homework…. Or flash another…. All Max is doing is a quick review… It’s up to YOU the reader to try it… He’s not putting a gun to your head to use the ROM he’s reviewing…. Don’t like this site…. Go to xda and shot down and burned for dumb, rude comments …. Love it or leave it.


    • fred says:

      I am here at max’s site because I bought the s3 and really enjoyed his tuts and new roms. I have told hundreds of people about it, but he has commercialized it beyond what I and others think is reasonable. You can’t even watch his mp4 without having to watch the older woman get her NEW MOM!
      I like max and what he has done is to be commended. but, it’s not the same, and neither are the roms. I must now assume that it is my phone that time’s out the keyboards on the last two roms, but I don’t get it the rom’s I got here ALWAYS worked.?????

  11. Cody says:

    Hey max,

    I was running BeanStalk ROM. I really liked it, but I love to be always looking for the “perfect” ROM. I flashed this ROM today and so far it’s working like a charm! Right now the battery is poopy though, but I have been using it non-stop. Other than that I have no complaints :). Anyways until next time!

  12. faizan says:

  13. ben says:

    can anybody tell me if this rom is working flawless on the sprint s3?

  14. Hendry says:

    Carbon has JB 4.3.1 available more than a week ago! It was developed for AT&T and works perfectly fine with my SGH-747M Canadian Bell Galaxy S3 as well!

  16. JESSE ONE says:

    No worries Fred… Totally see your point of view…. Still love the site…. As for the ROM itself… Its solid…. But the best… STABLE roms so far on the D2ATT… (code for S3 on AT&T) SLIMROM 4.3 and LIQUID SMOOTH 4.3 (test ver. both are great..

    • fred says:

      where have you gone???????????????


  17. Steve says:

    Going to test it out now. Will post back in a day or so with feedback.

  18. Homer says:

    Tried this for a few days on Tmobile T999. It was ok, but not really stable or fast. It was much slower than CM10.1.3 stable.

    I went to CM10.2 nightlies (now using 4.3.1), and it’s much faster and more stable…
    Sticking with CM10.2 nightlies for now.

  19. Zach says:

    After attempting to install on my tmobile sgs3 I got build prop 7 error. How can I fix this?

  20. Brandon says:

  27. haniyf says:

I can also not find anything on my sch-r530x its like non existent any advice will help.. I’m a noob but I have done my research.

    BTW this has been the most helpfull of all sites I’ve researched (going on 90hrs of forums and how to’s) ready to ask for help.


  29. lejojaluel says:

    I had a problem on my i535 it has not responding almost making the phone incapable to use……but when I put it in airplane mode it stops the error.

    • Max says:

      That may happen sometimes, it didn’t install correctly, try formatting /system, then reinstall ROM.

      • lejojaluel says:

        Will do And one more thing. I have a Galaxy S2 T-Mobile. It was a zip that is a super wipe. Dark Side Super Wipe. I was wondering if there was anything for my I353. And next r

  30. Senya says:

    I installed this ROM on a Canadian S3 it works amazingly fast and stable, except for one thing; CALLER ID is not being displayed correctly. If someone not in my contact list calls me it’s just gibberish instead of persons name.

    Unfortunately if there is no fix for this I will have to change this ROM as this is a busienss phone and I prefer to know who is calling me,.

    Anyone with the same problem or fix out there?


  31. Jay Estrada says:

    Is it mandatory to wipe data/factory reset? What would be the consequence if i dont do that? Someone please answer!

  32. Ron says:

    This is nice. I like the new camera the best. I put this on my I9300. I used the fixes mentioned earlier in this thread, not I had no issues with the install. But, after an hour my apps stopped working. I’ve rebooted and reinstalled my apps, but eventually get the “unfortunately this app has stopped working”. I’ll try a different mod, but I’ll keep the camera.

  33. ronald says:

    please help, i installed the rom and gapps package, but there is no sound at all, and i cant seem to find my files folder or music player, thanks

  34. dally says:

    I use vanir with ktoonsez kernel as my daily driver on at&t s3, and it runs great ! Everything works fine ! I love it. Great ROM, good job.

  35. Wayne says:

    Hi, I would like to check out this ROM, but I am gun gun shy after my last experience. I think my problem is this knox thing everyone is talking about. I thought I had bricked my phone, but managed to complete the Wicked Sensations installation using a guide that involved removing the battery/USB cable, etc… My warranty bit is 1, but I don’t care about that. Will I have the same problem if I try to flash again??

  36. Justin says:

    I had this rom but couldnt make it work. The phone ( would always fail over and over so I put ThePeoplesRom back on my S3. I couldn’t get any kind of signal with Vanir even after the update. I’m going to try CyanFox when its finished dl’ing.
