For those of you who want a pure CM10 (CyangenMod 10) Jelly Bean ROM Android 4.1.2 experience (without the additives), try the HellyBean CM10 port for your Galaxy S2 GT-i9100.

This ROM is near flawless in terms of showing you a “pure” CM10 experience with Android 4.1.2 and the latest goods from CM10 sources.

On the latest CM10, you will find that many of the UI customizations from AOKP are now baked in including stuff like weather/calendar widgets, slide brightness control, and a whole lot more.

Also, the battery very good on this ROM.

I find there’s a ton of great AOKP ROMs out there (which I do like also) but sometimes you probably want to experience what a pure CM10 ROM feels like. This is definitely the ROM for that, so give it a twirl this weekend and let me know what you think! There’s also couple extra features added so you have nothing to lose.

Features added to CM10:

– facebook sync integrated
– option to enable high end gfx effects
– possibility to activate and customize navigation bar (color of background, glow effect, transparency)
– possibility to customize statusbar (color of background, transparency)
– transparent lockscreen (taken from paranoid android, coded by jesus david)
– edge swipe navigation (ported from sgt7)
– ability to enable tablet_ui (ported from aokp)
– kill-all button at recents panel (ported from aokp)
– task manger button at recents panel linked to the built-in running apps service
– customizable long-press-back-kill timeout (from 500ms to 3000ms)
– added option to toggle lockscreen styles (jb, ics, gb, eclair)
– option to use sense4 recents panel
– misc settings in settings menu
– added kill-all and taskmanager button to sense4 recents panel
– added the possibility to set lockscreen text/image colors
– added possibility to change the colors of the statusbar toggles
– added option to enable/disable coloring of toggles
– added option to display a small bar below the toggles as indicator for toggle state
– added possibility to display additional volume slider (similar to brighness slider from aokp)
– pdroid compatible (settings –> security)

    Hello Max . I have Siyah kernel v 4.1.5 with paranoid android v 2.1.3 installed on my phone and I’m wondering why I can’t get hellybean to boot as a secondary Rom even when it say’s it’s installed . All I get is a black screen and no boot . I have tried everything I can think of doing , including a backup of PA then factory reset and wipes and a clean install of Hellybean and it works as a single Rom , but not with Siyah and PA . Any help would be much appreciated .

    Very good one…..of all jelly bean roms i have installed this is very stable and smooth but BATTERY is draining fast…so i flashed siyah kernel but no use……thinking of going back to cyanogen mod 9.1 which is very good at battery saving…..canu suggest any ideas to improve my battery life

    • Peter Svensson says:

      Hallo srinivas769

      • Peter Svensson says:

        Think i fixt it was miniusb connection dirt and have to use a toothpic to fix the metalplate inside working now

        • srinivas769 says:

          Hi Peter Svensson, when i first installed this jelly bean rom battery drained faster…so reverted back to cyanonogen mod rom 4.0.4 which used to give good battery life but due to change in baseband version to XXLPS(which is because of jellybean rom) it also started draining battery faster. So i am back to jellybean rom….i think changing baseband version may solve the problem

  25. Andor says:

    Hi Everyone!
    Just a quick question…could anyone change the screen density for this ROM? (for exapmle from 240 to 180) I’ve tried with ‘LCD Density Modder’, ROMToolbox, or by editing the build.props manually, so far nothing worked, I’ve ended up with a black screen at the startup.
    Any possible solutions?

    Thanks ๐Ÿ™‚

  26. shlrocks says:

    Using it for the last 2 days and loving it..! Battery is a lot better than paranoid android 2.21

  27. Shadrach says:

    rocking it now.very stable ..high on Android

  28. sebastian says:

    Someone have problems with 3G data in sud america?

  29. hadiabu says:

    Been an avid RR follower but have to admit this is one of the better alternative out here. Been using it close to a week and i love the stability it provides.
    Battery life improves slightly.
    Email(config under exchange) works unlike RR 3.0.6.
    Trebuchet as my default launcher since Nova experience glitch every now and then.

    Apollo force closes. No issue here will just go ahead and install other player.

    Thanks Dev! Great job here!

  33. Steph says:

    Hey Max ! I got a problem.. I’ve installed the rom and everything is working properly ! But I Have a little problem and I thought you might be able to help me. My volume buttons are broken due to my motherboard but that’s not a big deal, the only thing is the CWM is working with volume buttons only so I can’t try new roms anymore. What do you recommend me ? May I install a touch CMW by the download mode ? And.. which one should I install.


  34. KG says:

    Unfortunately it restarts all-the-time.
    I’ve installed this ROM yesterday, and after setting up my apps (email with IMAP, 3 GMail accounts, etc.) it started to restart very often.At least 25 times, since yesterday afternoon.
    There are periods, when it works like a charm (I really like it), but there are periods, when it restarts every 3-4 minutes. It happens when the phone sleeps, so I can’t catch any messages, just realize that it asks for the PIN code again…
    Any ideas?
    Thanks in advance.

    • hadiabu says:

      i encountered such problem when using siyah kernel before. did the normal wipe data/factory reset and wipe dalvik cache seems to solve it for me though. U may want to try these and if still fail at least can still restore back to your last working ROM. Cheers!

    Hi everyone,

  37. Bakir Al Tikriety says:

    Is it illegal to download such a ROM?
    Can Samsung know that I installed such a ROM and cancel my guarantee?

    • Fry says:

      Installing a ROM is perfectly legal, but it requires root access to your phone, and rooting voids your warranty with Samsung. You can use software to unroot your phone and install stock SGSII ROM if you ever need to get your phone replaced or repaired. There is an unrooting guide on this website, check it out.

      • Bakir Al Tikriety says:

        I asked Samsung support, if i can download a ROM from internet!
        They answered: ” your guarantee would be cancelled, if you download such a ROM”
        Is it true? Can they know that i download such a ROM and cancel my guarantee?

        • Fry says:

          Absolute bollocks. No-one except your internet provider has access to that information. If there is a ROM installed on your phone when they inspect it during your warranty period, however, it will be voided.

    After Installing this ROM, is Anybody facing issues like WiFi is not working ?
    Cant connect to the Internet Via WiFi on this ROM.
    Any Suggestions ???



  44. hadiabu says:

    one thing i notice is the batt life is awesome when it is sleeping or in other words you are not using it. Example i can leave my hp at my desk when i go for a meeting and 6 hours later when i come back it will only drain out 3% of it.

    However when using it though it is worse than before. Browsing 2 minutes of FB can bring your batt down by as much as 5%-8%. already lower down the screen brightness or even stop all the running apps when browsing but results are the same. Any chance this has a solution or this is how it is?

    • Rebelpriest says:

      Same observation and same effects on mah phone.

      Is there a way I can add toggle buttons like 2g/3g ,etc ?

      • hadiabu says:

        Hi Rebelpriest

    Hi there! ๐Ÿ™‚ And first of all, many thanks for all your vidรฉos, that’s a great help!
    I have just finished rooting my galaxy s2 i9100. I would like to get rid of my operator stuff and to get the jellybean.
    My version of android is 4.0.3. Just underneath I have “I9100XXLPX”. And the version of the kernel is Siyah.
    Could you please help me? I know that we have to download CM10 ROM Android 4.1.2 Gapps. I have already done that but when you say that: “To install, reboot into CWM Recovery, wipe data/factory reset (unless you are coming from another Jelly Bean ROM), install ROM, install Gapps, wipe cache, and reboot. Thatโ€™s it!” It’s not that simple to me. So could you explain it to me step by step?

  58. Jan says:
