  • Sim_Piko says:

    pytanko, odpala to cudo gta3?

  • matt96g says:

    Hi maclaw
    can you make a great CM10.1 (like what was your cyanogenmod 9.1) for your next project??

  • Keefer says:

    What the major difference between AOSP and CM? I am excited to see your release and would love to try it. How much memory is left after install? CM9.1 RC4.1 from Wayland_ACE has 177MB. Is AOSP more lightweight? Does Voice Search work?

  • Bolokov says:

    Hi Maclaw. I just wanted to say welcome back and say that I really like your roms and that you should keep doing them. Don’t let other people affect you, keep doing your great job and giving us the OS we could never get.
    Kudos from Portugal 😀

  • Keefer says:

    Would you be willing to start development on an AOKP for ICS? That project seems to have been abandoned and never reached a very stable point.

  • John says:

    Welcome back Maclaw Studios! The best developer for Ace is back in town! I’d like to see 4.2 AOSP or CM. Thanks for coming back!

  • IsaFarady says:

    thanks a lot guys,really nice ROM
    glad to see you back 🙂
    I hope you will try to make stable AOKP ics and ParanoidAndroid 3+ for your next project 😉

  • Zozol says:

    Jak będziesz zmieniał telefon trzeba zmienić na taki jak Ty, żeby nie tracić deva 😀

  • suddenyap says:

    If I’m using your CM9, what should i do? Clear what?

  • Baptista says:

    Nice work! It would be awesome to have 4.2 on my device!

  • István says:

    Flyme OS 😛 i read on xda that flyme os is ICS based (?) . i think you can do it i love your roms:)

  • xwinnernikx says:

    omg is that smooth !!

  • qqv says:

    hey maclaw make please cm9 😉

  • Kevin says:

    THANKS. Aosp jelly bean 4.2 or cm10.1 would be nice.

  • desmaize38 says:

    I get a reboot when watching yt vids

  • IVAN says:

    maclaw , when i flash this rom … i select the languaje ( spanish ) and reboot a lot i did the wipes and nothing ¿ what can i do ?

    • Bolsapryca says:

      I’m having the exact same issue.

      I’ve tried to change the language in the selector to English (US) and it keeps rebooting…

      Any solution?

    • carlosace says:

      It happens the same for me. I cant pass from the first language selection screen. when i click Start, it freezes and then reboots.

      Pd: im on Ace

      • Macław says:

        Wipe dude, it must help!

      • Rapisho says:

        Same problem here, I already tried dalvik, cache and factory reset before and after installation. Sometimes it says not responding or something like that when selecting language. Btw the boot animation is shown every ~20sec in language selection screen.

        • Rapisho says:

          I think it has to do something with the region of the SIM card since everything works fine when doing the installation and initialisation without it (starting the phone then with the SIM card inserted makes it reboot again and again, although homescreen is shown).
          In my case its germany, and on XDA I already read from another german user that he has the same problem.

  • Miral1000 says:

    Welcome back maclaw
    I will wait until Jelly bean rom First release from you 🙂 (4.2.x if possible) 😀

  • rrd says:

    Thank you Maclaw.
    First problem: automatic time setting is 1 hour behind. Select time zone not working.

  • Dher says:

    Next ROM? CyanogenMOD!

  • DraKai says:

    Thanks for that 🙂
    We want CM 9.1 ! 😉

  • Mariush90 says:

    Nice to see you back guys 🙂 I have already installed this relese. It works very smooth and stable, but i’ll be very greatfull if you add more system configuration options in next update/relese. I can’t wait for 4.1 or 4.2

  • c3m says:

    Thx u 4 all…
    Happy to see u again…

  • ingyesid says:

    Thank you. Welcome back. \o/

  • winxuser says:

    yesssss!! welcome back guys, i have been hanging for a maclaw release since you stopped and left xda. your releases were great… to all the people asking for jelly bean releases, please wait as doing AOSP isnt easy and i know i would like to see fully working ics before jelly bean

    Other than that and time zone bug, smooth as a butter 🙂
    Thanks for the great work

  • Thanks for all Maclaw, you are back online 🙂

  • Aidan says:

    WOOO! Yay your back!! Great build, but could your next build be CM10! Its my favorite ROM, but the only thing I don’t like about it is how the launcher is too big for the screen / out of proportion.. Thanks, and cognates on coming back!

  • Bonafide says:

    Seems good, downloading it now! Will try it later today!

    For the next ROM, I’d like Android 4.2.1 with Photo-spheres and everything! 😀

  • Dmitry says:

    And here we go again… People don`t be an ashole. He just did AOSP rom and you talking about: “Make please AOSP JB rom…” He will make
    it, as soon as posible. Be patient! 🙂

    Maclaw and Marcin thanks a lot for your great,hard and brilliant work. I`am very glad that you are back.(Ukraine with you)

  • cyper d' oxide says:

    bluetooth cant use.. Select time zone not working. btw.. wlcme back…

  • Valyi says:

    How can I change the number of screens(desktop) ?

    • Keefer says:

      Its AOSP. Comes with the stock android launcher which is limited to five screens. Download a different launcher from the play store.

  • MOiS says:

    Maclaw…. U Are just awesomeeee…… Love ur rom very much…. U made a smoothesstttt rom…. Just make it stable for my daily use rom… THX…

  • Noizy says:

    Great rom, Stable 😀 GREAT WORK GUYS, Best Team Cames Back 😛 😀

  • afaik says:

    hey! great to see u back and ur amazing roms! AOSP is just a great work.
    i have problems with location.
    is anybody else experiencing the same?>

  • Michal says:

    It’s fun, something that moved
    Maybe it will be a fully functioning rom for GIO

  • Thiago says:

    You are brilliant.

    One of the best ROM already tested, fast, stable, no fc, great battery and sound amazing. Hopefully in the next version is corrected question Automatic Time. Can not log into twitter with this bug time.

    Keep up the great work guys and sorry my English.

    Greetings from Brazil.

  • Tadeas says:

    For Ace, are there any other issues beside Bluetooth and video recording?

    How does it compare to Wayland_ACE’s CM9.1 RC4.1?

  • Wow – so much faster and smoother than Jellaxy 4.2 AOKP.

    Really pleased with this – many thanks.

    Next could we have 4.2.1 AOSP please?

  • shiftyHungary says:

    Well rom seems to be running nice and smooth, really, there are just minor bugs, overall:
    -Date zone
    -Data counter (not counting any data transfer)
    -Kernel with Init.d support (I don’t know if AOSP supports init.d)
    -Random freezes, making the phone totally unusable – have to remove battery, and start again
    -YouTube reboots, however, HQ playback was working awesome 🙂

    I think that’s all, if we don’t mind those bugs, which you already stated 🙂

  • skybrake says:

    Nice work! nice rom.
    thanks from Indonesian user

  • Manu says:

    Network location is not working

  • Sergio says:

    Hi guys!
    You’re doing everything right! Thank you for that!

    How can we apply ext4 on memory card as a internal storage in your AOSP ROM?
    On CM9 they have a couple of scripts for this purpose.
    You see, there is a very big lack of internal memory on SGA, so it’s a very important thing.


  • Roman says:

    Can Google Now work on Galaxy Ace? Please make 4.2 JB ROM, if U can!
    From your Russian fans

  • Charles says:

    MAC addres changes after reboot. I cant login to my mac filtrated network :/

  • yunusx says:

    i will test it i hope it is succesful

  • EddyTheSensation says:

    Hey Maclaw & Marcin!
    As you asked what ROM next, I’d really like to see a HTC Sense 4+ (I mean the one on an HTC One X+) ROM by both of you. It would be very cool to see a Sense Port to our Ace, as I am a Fan of Sense!
    A lot of people like Sense, as it simply looks stylish! 🙂
    Keep the fantastic work up!

  • Tomas Brod says:

    I am happy for this rom, but I will stay on cm7 until it gets stable. And I cannot have my Ace without some of great cm7 features. My backups of original samsung rom got corrupted and i know i will have to return this device so i need original rom. Thanks Tomáš zo Slovenska

  • luukvideo says:

    Welcome back maclaw! always using your cm9 ROM and now this amazing rom! thanks!
    ps- GPS seems not to be working. maybe look in to that?

  • Fábio Barbosa says:

    Hello there.

    When using Spirit FM and even after following your instructions the app is returning a message error saying “Error: No FM accessible”.

    What could be behind this issue?

  • Indonesia Fans says:

  • Keefer says:

    Does voice search work?

    Screenshots please.

  • badack says:

    I’m glad I still have this site on my bookmark list….. 😀

    since i’m already fallen in love with JB, I’ll just pass on this ROM.
    but once you got a JB-based ROM, I’ll test it right away….

  • suyashagrawal says:

  • Ivanokaze says:

    Hey maclaw! very nice work on the AOSP! i have a tiny bug for you, though… i don’t know if there is a place i should file an issue.. maybe github or something like that. anyways here it is: vanilla ICS AOSP(no apps installed except the standard ones). even though the mobile data is disabled from settings, the signal icon in the status bar appears as if 3g is working.

    keep up the good work!

  • Lucas says:

    @gio — The rom starts again and again. 🙁

  • lucas says:

    Jak uruchomić live wallpapers na tym modzie?

  • toy203 says:

    After a clean install (format sd, format phone memory, factory, cache and dalvik) the phone is stuck at the boot language selection. Cannot go forward and keep looping the boot animation.

  • Quincy says:

    I’ve used you ROM for a few days now a I didn’t manage to find anything that bothers me except that youtube reboot thing. It’s a great ROM man, keep up the good work :)Oh and btw, I found a fix for that Youtube reboot thing, but you might be allready aware of that, but here’s the link:

    Greetings from Belgium 🙂

  • Kamil says:

    trochę się jeszcze zwiesza.. Ale z wyglądu jest ładny. brakuje też skrótów na pasku

  • rcolaco says:

    Very nice a smooth rom. THANK YOU very much.
    I’m using this ROM now and wishful for, at least, Bluetooth working because of car hands free system. Of course to have Video recording working would be also a nice to have.

  • Ous Anonym says:

    Whenever the ROM boots up, it shows a pattern lockscreen that disappears after a moment, then it says encryption unsuccessful. When I click the `factory reset` button on that screen, it doesn`t do anything. I have tried factory reseting via CWM, though the same message appears. Perhaps its because I am on S5660M?

  • Nick says:

    Bugs for me:
    -I have secured my phone with the gesture but if i lock my phone with the on/off button on my phone and then unlock the lockscreen doesnt appear. If i lock the phone with a lock screen widget on my homescreen the lockscreen appeared.
    -I can not synchronize my google account with the browser.
    I am om ace and i am using alpha 1.

  • Arnee says:

    Buggy but ok, but in the end really good work. Congratulations!

      I suggest you try using some widget for functions you missed in this AOSP rom.

  • marcuz says:

  • Anand says:
