    Hello, Lollipop works great so far on my s3 mini.

    I had to install 5.1.x Gapps because I got some errors for the ones in the link (5.0.x)

    It works nonetheless and my bluetooth is back 🙂

    Another question:

    For some reasons I no longer have root access.

    What would be the safest way to add that?

    Thank you

    • @botaflorentin:disqus just download latest version of and flash it using recovery. you should have the root access then.

      • Bota Florentin

        You sir have my thanks!

        My phone works better than ever before.

        The fact that I installed only the basic google apps (pico version) also helped

      • André Sousa

        Hello Usama,

        I can’t install Gapps either… I did what you said to Bota, but i still get the same error on the gapps installation. Should i start all over with the CM12.1 install?


      • Panos Stathopoulos

        the link got outdated :/

  • André Sousa

    Why my comments are always erased?

    • @disqus_So6OLBIIe4:disqus non of your comments are erased.

  • Niall Girl!!!

    Hi, I would like to know if it’s necessary to download TWRP and Titanium Backup if you have nothing on your phone and will be using it for the first time? Also, should you download both or just one?

    • @disqus_WmC5hboL70:disqus you may drop Titanium backup, but TWRP is required to falsh the firmware.

      • Niall Girl!!!

        Thanks so much. One more question, what’s the difference between Nandroid Backup and EFS backup? Should both be done?

        • @disqus_WmC5hboL70:disqus Nandroid is the whole system of your phone. EFS contains radio and mac addresses, which are responsible for network connectivity of your phone.

  • Khom Sovannraksmey

    do I have to follow step 2 and 4 if my s3 mini is already Rooted through Kingo Root?

    • @khomsovannraksmey:disqus you must have a custom recovery to install the firmware. If you already have a latest one installed, you may use that.

  • TommyLau

    It says E: Error executing updater binary in zip, please help I’m unable to boot my device normally now, it goes automatically to TWRP recovery. I download cm 12.1 and gapps, i wiped everything, but still it doesn’t work

    • Akmal Lond


  • Oscar Ulate

    Does the video camera still not working? I mean, what are the chances for it to fail? Thats the only issue that stops me from upgrading. Thanks

    • @oscar_ulate:disqus if the stock camera application doesn’t work, you can also try using any third party camera application from Play Store.

  • Spartacus XL

    hello I install firmware, now my device working

  • @rewanwatti:disqus you can backup everything by backing up Nandroid, Titanium Backup, EFS Backup, SMS Backup, Contacts and call logs. After that you can perform your desired operations.

  • @rewanwatti:disqus in the guide linked above, I’ve attached all the necessary guides. Those will help you. Best of Luck 🙂

  • Mohammad Rafizi

    Hello Usama, I had some issue. After I install the firmware, the touch button back and option seems not respond. But, the firmware works great so far on my s3 mini and all your guide help a lot. I wish you have an answer. Thank you for you hardwork !

    • @mohammadrafizi:disqus boot into custom recovery and wipe cache and dalvik cache. It should work fine. Best of Luck.

      • Mohammad Rafizi

        @usamamujtaba:disqus GG. =.=’ Still problem. In reboot the both touch button keep blinking a while. I think the hardware is fine and I should wipe and flash again with the ROM and gaspp. Maybe my mistake in there. Shouldn’t I ? Anyway thanks for your helps.

  • Brad Varol

    Great article, thank you 🙂

  • Peterpainter

    i guess the download is down.

  • Daniel Valverde C.

    Hi, does this work with galaxy s3 mini gt i8200L?

    • @danielvalverdec:disqus yes it does. Best of luck.

    • Juampa

      Have you tried it for real..?? I want to install this also on a 8200..

      • @disqus_UuVBZThTcK:disqus Works with 8200.

        • Juampa

          I’m not asking if it works, i’m asking if someone tried it.. I did some research, and in several forums all users point that i8190 and 8200 have different hardware, and that all the 8190 roms would brick 8200… I just dont want to waste my time, thanks.

  • בן

    download doenst workk :(((

  • Nikhil N

    Will there be any problems once lollipop is installed? And would I need to have free memory on my device

    • @disqus_mQyEy0Rk45:disqus Since this is a stable ROM, I don’t think so that you will come across any issues.

  • Nikhil N

    Will it work without a rooted device

    • @disqus_mQyEy0Rk45:disqus you just need a custom recovery installed on your phone.

      • Nikhil N

        Thanks it work well
