  3. michael says:

    when i download the file it is stating that it is an end of archive. What does that mean?

    • HaloHeavy says:

      Means you should learn more about computing before potentially bricking your phone.
      Sorry =\

      • Inappropriate says:

        It means he asked a question so please answer it instead of being a smart ass. He could be new to this just like many people out there.

        It means that the downloaded file it either incomplete or corrupt.

  4. JSR33 says:

  5. daniel says:

  6. James says:

    Good ROM so far but i get issue when someone calls it come up as an international call with a + in front of all the numbers

  7. Robert says:

    It seems to be a little slower than JB 4.1.2 and not as smooth. I may have to go back to CM10. I’m getting ocassional crashes on some apps. WHY do I still have my old file directories from my old CM10 rom on the new install of this AOKP rom? Is there a way to undo this? Wiped all cache and did the factory reset. but I still have all my old files/folders? Any help would be appreciated. Thanks!

  8. Arthur says:

    I am on cm10 stable and have been using it as my daily driver is this rom worth flashing what are the advantages I mean ther is still no photosphere.

  9. jsr33 says:

    I flashed this ROM and it created a 0 folder which was a Hassel to get everything back to its correct my pictures couldn’t be located nor my titanium back up folder.and the quick reply featured doesn’t really it doesn’t even have sphere cam.I went back to liquid smooth rc9

  10. Andrew says: You guys do a great job. For all you others out there in Webland, you have to make mistakes in order to learn. I would have to say that it’s pretty hard to irreversibly brick this device. You must read forum after forum and watch tons of vids to educate yourself so when you brick the device, and chances are you will, you know how to resurrect it from the dead. Don’t give up! Have fun with this stuff; it’s the culmination of somebody’s hard work. I must say that I am grateful for all you time and effort! Thank you, Merry Christmas and Happy New Year! I’m really looking forward to seeing what you come up with next! Thank you all again!
    Yours Truly,

  11. Mark says:

    Heya, great site and how-to’s thanks! Have flashed this ROM and can’t seem to get LTE working. In Canadia on Rogers/Fido network. Has anyone had any success with LTE north of the border?

    • Kkeuss says:

      Having the exact same problem here. I’ve noticed any changes I make to the preferred network mode doesn’t stick, whether I wait a few minutes and go back to view it or when I reboot/shutdown.
      – I sometimes am able to pickup LTE but that’s after numerous attempts at trying to get the preferred network mode to stick.
      – I’ve been running AOKP 4.2.1 Jellybean 12.23.2012 – I plan on trying CM10.

      I hope this is a problem that will be resolved in the next build, because I love AOKP.

  12. jose says:

    Can i run this ROM en galaxy s3 t999??

  13. Howard Denardo says:

    Any “s voice” ?!?!?

  14. Dylan says:

    Is anyone else having issues with charging the device it only seems to charge when I have my phone off. When the phone is on it says charging but it just stays at the same percentage. Sometimes it will go up one or two every like half hour. Also wherever I would have 4g it reads 3g and where I have 4glte it reads just 4g I have all the network settings good.

  15. Chris says:

    Love the rom… Except for when I try to call it puts a + in front of the numbers and gives me a message about international calls… And when I receive a call it doesn’t show the contact name. Just the phone number with a + in front of it….

    Also, the quick reply feature causes a force close!

    • Jason says:

      I’m having both these issues as well… Hopefully they find a solution in an upgrade soon… Aside from that, almost everything works beautifully

  16. Al says:

    I’m using straight talk att, it wont let me chose the LTE/GSM/WCDMA.. automatically goes back to gsm/wcdma

  17. shannon williams says:

    i am also unable to get this thing to select lte mode. just stays on 3g and h. keeps flicking back and forth. any other good 4.2 roms for att s3 with the photosphere and 4.2 clock?

  18. deven says:

    Is anyone else having weird issues with this ROM? The camera freezes multiple times and says “can’t connect to the camera” and it doesn’t save the picture. Also, on the AOKP keyboard, when I want to use text to speech, it pops up then force closes and won’t let me even bring up the keyboard until Igo into CWM aand wipe my cache. Anyone else?

    • Jared R. says:

      Had this problem before too, but the newest 1.4.2013 build seems like the problem went away. Do a system wipe and flash the update. This update seems to be running smooth like butta!

  19. Daniel says:

    The boot screen just endlessly say initiating swagger what do i do??

    • calvin keller says:

      If you are coming from another rom that’s not jelly bean. You should factory reset and wipe the cache and davik cache and it should fix the boot loop

  20. Howard Denardo says:

    Any svoice figures ????

    • Yash says:

      No, just Google Now. You may be able to flash the s voice apk though.

      • Jarof says:

        Yeah you can flash the svoice apk but the problem is that it no longer works with all the new apps. Since all the apps are now google based it seems like it lost the link to similar apps and will no longer do anything

  21. Josh says:

    Sorry, but I’m still new to rooting and flashing. how do i remove the 0 folder?

  22. Mushtaqc says:

    I just rooted/CWM my SGS3 Rogers 1747M, not yet installed any customize ROM, do I still need to wipe all data?

  23. wilfredo says:

    Hi max and happy new year
    I im trying to perform the update from 1.1.2013 to this rom. It downloads but when it goes to cmw it gives me some kind of error is there another way to download the update. Thanks

  24. Redmoon says:

    Hi, there
    I installed AOKP yesterday on my ATT SGH-i747. However, I found that the google voice, even other voice related apps did not work, it just popped up an information that ‘unfortunately google search did not work’.
    Then i tried to wipe data and install it again, however, either the Volume Up+Center Home+Power button and Volume down+Center Home+Power button did not work.
    So what should i do right now?
    Thank you very much.

  25. Jared R. says:

    hey max what’s good?

    I flashed this ROM to my T999 and noticed that when I’m Mobile that is 3g and not 4g. Sometimes and not steady it is picking up H which I am assuming is 4g, but with other roms including out of box stock, I have been steady 4g no problem. I have flashed a few new modems to see if this would help, but really nothing. I am thinking that it is just the theme that makes it say 4g, but then when it pops to “H” then I am kinda wondering..

    Any way to get this fixed? Any modem recommendations?

    Thanks again in advance

  26. calvin keller says:

    I previously had this rom but switched back to stock because the notifications for certain apps such as facebook, twitter, snap chat etc were not being displayed in the notification bar. Has this issue been fixed On the latest update?

  27. alvi5 says:

    Can’t seem to find lockscreen shortcut modifications can someone help?

    • John says:

      Hey Alvi5,

      When you first turn on the phone you will be at the LOCKSCREEN…from there you can SWIPE YOUR FINGER TO THE LEFT to have the CAMERA.

      If you SWIPE TO THE RIGHT you will have a SHORT CUT to a DEFAULT WIDGET (which can be modified)…continue swiping to the RIGHT then you will have a PAGE WITH A (+) SIGN, from there you can ADD ANY SHORT CUT (WIDGET) that you like by TAPPING ON THE (+)…the widgets you see will be limited…you can have more widget appear on the list by going to SETTING>ROM CONTROL>LOCKSCREEN> then CHECK MARK (ALLOW ALL WIDGETS)…now go back to that list then you should see more widgets for your short cut…just a reminder that you can only create up to a maximum of 6 SHORT CUT WIDGETS (INCLUDING THE CAMERA THAT I MENTIONED)…so use it wisely.


  28. john says:

    I’m unable to create a wifi hotspot using this new ROM. Before flashing to this new ROM, i was able to do so using WIFI TETHER from the PLAY STORE. Anyone can help? Please…

    • Jason says:

      I am also having the same problem with wifi tethering. But I’m sure the developers know about this and are working on a solution.

      The problem lies in “connecting AP”.. weird cuz all 4.1.2 roms tethered without any problem.

  29. frys says:

    How do you do a screenshot? I miss the palm swipe

  30. Jason says:

    Or you can press and hold the Vol down and power buttons at the same time…

  31. Jared says:

    Really good rom, thank you for sharing!

  32. richt says:

    I am having an issue with the phone after the latest update. The volume shows its going up an down with key press but the volume never changes as its locked on like 50% volume and when put phone speaker on you can barely hear as well. Is there a fix? Is anyone else have this issue with the updated ROM?

    • John says:

      Since you mentioned…I checked and I do have problem with the SPEAKER VOLUME. The sound does not increase or decrease when it’s on speaker mode.

  33. richt says:

    I really appreciate you updating the ROM so quickly! Thankyou !!

    After I took the new update everything worked fine for a while. Then just tried to make a phone call a minute ago and it quit again volume. Tried rebooting and even resetting factory and clearing the caches and installing clean copy of 1.8 and still does it after a while. Please I love this ROM the best out of all out there and would love to see this permanently fixed. I would also love to donate if you have a link somewhere for all your hard work! Thanks!

  34. Yan says:

    This room did not work for me. I stuck on the loading animation . It wont go in to the system

  35. richt says:

    I found out what is causing the phone volume issue! The beats audio installer! After trying everything I restored my apps one at a time and kept trying phone after each. When I installed beats audio it quit! I had to clear both caches and reload the gapps and the ROM. No need for factory reset. It all came up and worked flawlessly!

  36. richt says:

    I hope theres a fix for the beats audio as I miss it! Thanks for all your hard work on writing this app!

  37. richt says:

    Yes I can change volume in speaker mode

  38. richt says:

    Is there any feathering that works with this ROM?? I have for everything else to work except for WiFi hotspot. Thanks!

  39. richt says:

    Teathering is what I meant

  40. seshu says:

    I just flashed this ROM onto my s3 and everything so far looks ok except that all incoming calls are prefixed by + sign which does not allow me to redial the number as i get you are not allowed to call international numbers from my carrier. call went through fine when rmoved prefix.

    Any ideas?

    Thanks, Seshu

  41. Ivan Dobrev says:

  42. Daniel says:

    Hey Max, first of all thanks a lot for the great job with your website. I’m kind of experiencing a problem after closing some apps as games. The ROM runs flawless but after leaving some games it simply runs super slow do u have any clue about this problem??

    Thanks in advance 🙂

  43. tofu says:

    Hey guys. I recently flashed this ROM to a friends phone. And now he is having cell data connectivity issues. As in he isn’t receiveing a data signal but is getting full cell service. Could the ROM be the problem? Or is this likely an att issue?

  44. CarpeDiem says:

    Help Please. I ran the new jelly bean ROM, rebooted and now it shows the unicorn head with the words ‘initiating swagger’ but doesn’t do anything else. I have it on a AT&T Samsung S3 and am not sure what to do next. Any advice would be appreciated.
