  • Sinbad1422

    Installed the Biftor Rom and my UI is upside down, not sure why but I will try it again. I have a Galaxy S2(Sprint)

    • Samar Shiraz

      This ROM is for stock i9100 and not for sprint S2.. please use ODIN and switch back to stock ROM


      @Sinbad1422. YOU ARE such an asshole. Read carefully instructions when you are flashing any rom on your device. “This ROM is only for GT-I9100”.
      I’m pretty sure you will end, somehow, bricking your phone.

  • Ankit Meena

    bakwaas rom not use full screen size

  • Samar Shiraz

    This is the slowest rom i’ve used.

    I’m using DoremanX Kernal, but i thought the stock JB rom was better.
    Issues I’m facing:-
    1) Difficult to lock phone under Charging mode
    2) Doesnt charge the phone quick enough
    3) Battery time is barely 8hours ( 3G )
    4) Very Laggy
    5) Multi Window Function is not as good as i thought but very laggy
    6) Brightness increases automatically once we use Multiwindow.

    • Cloyd Dmello

      i have 2 similar probs here buddy…

      Battery life is really bad on v5.2 and the charge time is very long,…almost 6–7 hors to charge from zero to full…and wit wifi i get a 12 Hour lifespan but wit 3g it ws hardly 5 hours b4 the battery went blank…

  • Hari Sudan

    I have installed it.but multi window is not available
    Plz help me

  • Dazed & Confused

    Hi, I hope someone can help me. This ROM keeps crashing and I don’t know how to find out why.

    I am fairly new to flashing Android ROMs but am familier with Linux and reflashing just about every other piece of electronics I own. I tried 3 or four other ROMs before trying Biftor 5.1. I really like it, smooth, quick and has the Samsung Camera, FM radio, Keyboard and Multiwindow which all suit me.

    However, I tried Space & Time ROM previously which just locked up solid occasionally. That is why I tried Biftor, but it is much worse. It just locks up about 3-4 times a day, mostly while using it but twice I have come to the phone to find it in standby but warm to touch. Need to hold the power button down for a long time or remove the battery to reboot.

    Is there any way to determine what is causing it? I looked for log viewer apps in the play store but they either seem to be for app logs or they are system log viewers that say they don’t work under Jelly Bean anymore.

    Some advice or a link to an article or thread would be much appreciated. If I can’t fix it, I will have to try another ROM, but I just got this one customised just the way I want it.


  • Kalind

    This rom is awesome! Thanks for making it…
    Facing no problems

  • Zibi

    This ROOM is very good, but it’s have as well big issue.
    When i tilt phone and press lock button the phone freeze and i have to take out battery to reset my SGS2.
    Please fix this problem because this ROOM is worth it!!!
    Other think is that this ROOM is more stable and faster with “jeboo kernel” but STweaks is not supported.
    By now i give 7 stars. After fixing this problem It’s will be worth 10 stars!
    Good luck!!!!

  • Zibi

Right after updating from GB to JB, my phone battery start creating problem…. i have tried plenty of jelly bean custom roms (RR, Alliance, Revolt etc) including Super Nexus.. Sometime it shutdown automatically… and every time when i restart my phone it become 1% or 10% or 5% even if it is 100% before restart…. But if i kept charge it during restart it doesn’t have any problem… please guys tell me what should i do? i always do full wipe, format/system etc before installing any rom…..

    Hey Max,

    I installed this no problems, but i would just like to ask why Chainfire’s 3D doesn’t install the drivers for me??
    I have tried on 2 different roms and have the same problem?? maybe it might be something to do with the new way ive rooted? I used your method of installing Jeboo Kernal, which worked a treat, but for some reason, i can’t install Chainfire 3D??

    Also when i’ve installed Biftor Rom how do i over clock, as i can’t seem to find it through settings?

    Any help with this would be very greatful.



    • Rich

      V7.01 is out!!!…=]

    • chi
