Update Samsung Galaxy Grand I9082/I9082L to Android 4.4.4 KK With CosmicCM ROM

Samsung Galaxy Grand Duos is currently running on Android 4.2.2 and it doesn’t seem that Samsung will be bringing any further version of Android to this device anytime in near future. The only way to get your device a new life at the moment is the use of a custom ROM. Google has gone far ahead with its Android operating system, and currently it is at Android 4.4.4 KitKat which is far away from Android 4.2.2 Jelly Bean. If you happen to be a Galaxy Grand Duos I9082 or I9082L owner and you wish to get the latest and greatest version of Android running on your device, we’ve found a very nice custom ROM that will do the job for you and get a KitKat for your device.

ComicCM ROM by XDA dev k2wl  and is AOSP based custom ROM available for the Galaxy Grand GT-I9082/L. This ROM comes with some cool features that are added by the developer himself, atop of this, as metioned this ROM is based on the latest Android by Google, the Android 4.4.4 KitKat. Most of the custom ROMs have been lagging the double SIM feature, luckily, this ROM has a working Dual SIM mode.

In the following post we are going to update the Samsung Galaxy Grand Duos GT-I9082 and GT-I9082L to Android 4.4.2 KitKat using the CosmicCM 4.4.4 custom ROM. In case you’ve been looking for an upgrade, all you need to do for now is to follow this guide carefully.Samsung-Galaxy-Grand

    Dear Usama, i can´t copy de CM COSMIC it appears a notice thas says ” Your device stop working,” but i can copy normally de GAPPs and any other file. what can i do?

    • @inspyra:disqus are you getting this error while copying the file from PC to phone? if that’s happening, then its not something wrong with the file.. Please make sure that your device is properly connected. Another thing you can do is, use an external SD card and use a card reader to plug it into your laptop/PC and copy the files to card and give it a try. Let me know if it works or not.

      • INSPYRA

        Dear Usama, i tried with a card
        reader, and no problem copying the file, but when I tried to install it,
        all the process has been aborted, and the cellphone stop de installation
        of CM COSMIC,… I remember that when I tried to open the file in my lap top
        with RAR, I couldn’t, it seem that the file CM COSMIC is damaged.

        • @inspyra:disqus Give me some time, I’ll do some research work on the developer’s thread and update you soon.

          • INSPYRA

            Dear Osama i tried with this one v4.8.1 (it is the last version in XDA, everything perfect, but the Gapps are imcompatible. looking for GAPPS.

          • @inspyra:disqus thanks for letting me know, I’ve updated the ROM link in the guide as well now. I’ve also attached the new Gapps link. Give it a try and it should work fine. Good Luck

  • Dinesh

    Hi Usama,
    Call recorders are not working with this ROM. I tried with Androrec & Automatic Call recorder. Could you please guide me to resolve this issue….

    • @disqus_rOokepcG35:disqus if you may want to give a try to Dr Ketan’s Call Recorder as that’s guaranteed to work. Good Luck.

  • @sushant_b:disqus that’s good if the SIMs are working without issuing these commands. You don’t need to do anything else. Thanks for the feedback.

    • Nasser Al hadi

      GApps is NOT in this page!!
      Pleas give me another sit.

    Hi, install your version toy is happy for the speed, but you as experts, may install radio and OTG in the near future?

  • Eduardo Rojas Huerta

    Hi, install your version and I’m happy for the speed, but you as experts, may install radio and OTG in the near future?

    • @eduardorojashuerta:disqus no, it will result in soft bricking your phone, and you won’t get any OTA update while you’re on custom ROM.

  • Eduardo Rojas Huerta

    Hi, sadly I must say I take kitkat 4.4.4 from GT 9082L, sticks, restarts, I consume a lot of battery, all this from one day to another, it will be some virus, I have installed ESET. Thanks now I will make a down grade to 4.4.2.

    • @eduardorojashuerta:disqus you may try clearing up your cache and dalvik cache. No, there won’t be any virus and ESET is non of use. Android doesn’t need an antivirus actually. You may try downgrading or try using another custom ROM. But Custom ROMs are never bug free.

  • Mainul Islam

    after installing kitkat 4.4.4 external sd card is not showing so i cant move any file from/to external SDcard

    • @disqus_3gDhqrvJ9X:disqus try flashing the ROM again..let me know what happens.

  • Adrian Espino Zamora

    hi, my phone is a Samsung Galaxy Grand grand duos I9082L Duos, I followed the process and restart it but only after logo appears and does nothing more there. what should I do?

    • @adrianespinozamora:disqus clearing cache and dalvik cache will fix this issue.

    • @disqus_8AnyDdXwg1:disqus just flash stock firmware. Find the guide on our site.

    • @hirdeshkumarraj:disqus it’s working fine,what problem are you facing?

  • Hirdesh Kumar Raj

    Gapps is not downloading

  • Jorge Barrera

    I use cyanogenmode with KitKat 4.4.1 and is fabulous! But I have 3 questions 1.- I can’t save my pics directly to my sd card. Is possible to do? 2.- I read that KitKat have a call identificator for enterprises that works with googlenow but I can’t find this option. 3.- I read too about the left handed mode, but i can’t find it either.

    Finally what’s the difference between KitKat 4.4.1 and 4.4.4 versions

    Thanks for your help!

    • @disqus_HjrxjEt0tf:disqus this is a custom ROM, you might face so many differences between a stock and a custom ROM. About the SD card, try pulling it out and pushing back, and check the image location in camera settings.. There was no 4.4.1 was old, 4.4.4 is new. Obviously, the newer is better and enhanced.

  • Hirdesh Kumar Raj

    i am using android 4.4.2 kitkat(probam) but onlly single sim is working in my galaxy grand duos.so i wanna flash it & upgrade with cosmic rom 4.4.4 but samsung kies is not connecting with my phone.

    • @hirdeshkumarraj:disqus developer options should be under settings, if they do not appear, just open about device and tap build number for 7 times. About the camera, no idea about that, that might be a bug in this custom ROM.

  • Mesrop Khachatryan

    Hi. I have several questions.
    Don’t know much about rooting. Do I need to root first to use this ROM? What are the main 3 advantages and disadvantages?

    • @mesropkhachatryan:disqus you need to have a custom recovery on your phone.. root isn’t necessary, a custom recovery is. At first this is based on Android KitKat, 2ndly custom ROMs are much lighter, there is no bloatware. About the disadvantages, custom ROMs can have so many bugs.

      • Mesrop Khachatryan

        Thanks Usama,
        I can’t download the Cm_Cosmic zip file. can you please give another link?

        • @mesropkhachatryan:disqus Link has been updated. Good Luck.

  • Mesrop Khachatryan

    Help me guys. I can’t wipe the cache. An error appears and it boots the system. And in my recovery menu it says “Apply update from external storage is it the same as “install zip from SD”?

    • @mesropkhachatryan:disqus that means your recovery is still stock, you need to flash a custom recovery to flash this firmware. Please read the instructions carefully.

      • Mesrop Khachatryan

        Hi Usama, I am trying to install the custom recovery, in Odin it says complete but when I boot phone in recovery mode it’s still the stock recovery.

        • @mesropkhachatryan:disqus just flash any latest stock firmware in your device and flash the recovery one again after that. It will work fine then.

  • prabhjot singh

    bro my wifi isnt working after instaaling this rom,.,,. wat coud be the possible issues,.,.,

  • @disqus_pwVleXZnVS:disqus Many of the people are facing this problem. I guess it’s a bug in this ROM. I’ll look out for this at the developer’s thread and update the post soon. Stay connected.

    • Agustin Marcoff

      Please, I’ve the same problem. What can I do??

  • @ronnyadamczyk:disqus there’s a new zip file attached above. Please try using that.

    • RonnyA74

      Hello, sorry for the late reply. I’ve been away for a while.
      I installed everything again, now without any problems. When I reboot, the Phone stays at the startup screen “CosmicCM k2wl”. I”ve cleared cache and dalvik cache. Still my Phone won’t boot?

      • @ronnya74:disqus try flashing the ROM once again from scratch. See if the issue persists or goes away.

        • RonnyA74

          Problem solved, I just had to wait for about 5 min, then the Phone restarts. Still had a problem with wifi, so I installed a different kit kat firmware

          • Prabhu Ranganatha

            me too facing the same problem can you please share the kit kat rom file

        • Prabhu Ranganatha

    • @disqus_orO5GnZ1k6:disqus Do you have an EFS backup of your phone? Did you take an EFS backup before flashing the custom ROM? If so then restore the EFS backup ASAP.

  • @sushant_b:disqus No you only can install it using a custom recovery.
