One of the hotter ROMs right now is probably the Rainbox ROM (that everyone is tellin’ me about). Based on the latest Android 4.1.2, the Rainbox ROM gives you the best of Samsung’s latest features plus many cool features like Note 2 Gallery, Pop-up browser, customized icons, and more.

Probably the coolest feature on the Rainbox ROM is the multi-window feature (from Note 2), now you can enjoy full multi-tasking on your Galaxy S2 without even upgrading your phone to a Note 2. This multi-window feature works quite well and not too shabby in terms of performance compared to a Note 2.

If you haven’t tried Rainbox ROM, give it a go today and let me know how it goes for you!

      Install philz kernel for leaked jellybean official rom then ull get cwm then flash this rom

    • mike says:

      SGS2 problem with leaked jellybean rom I have instaled it and forgot to make a backup of the previous rom/ firmware for my I9100P. I tried to instal other versions of rom’s but after instaling them i get always boot lop and i’m forced to instal back the leaked version of jellybean an it always locks my sims after instaling it back… PLEASEE HELP MEEE (mike_CJ_X@yahoo.com)

  7. Fry says:

    Just tried this ROM out for about an hour. That was about all I could take. One of the most functional and least buggy ROMs I’ve tried, but the icons, textures and notification area graphics are just terrible. If you are coming from literally any other Jelly Bean ROM, I guarantee that you will wish you had the nice clean look of stock Jelly Bean back in an instant. I’d like the Galaxy Note 2 and S3 features that come with this ROM, but installed on a more stock interface. That would be the perfect experience.

  8. androsland says:

    Wow!! sick rom! but what about battery life?

    • salim sayyad says:

      Very stable rom but very sad battery backup and mobile get continously
      Heat.
      mobile stand by time Is for this rom 24 hrs. If you are using wifi then 1.55 hrs
      Please update v7 rom for better battery backup

  9. Dushan says:

    What about att galaxy s2 max?

  10. Allan says:

    I like the rom BUT, when I try to boost cpu with set cpu it only goes to 1200, usually fixed with installing latest siyah kernel but that doesent work here. And I dont get the toggles, really annoying!! Anybody know how to fix this?

  11. Allan says:

    The toggles came with a clean install. But I would still like to overclock to 1400mHz. Ant idea if there i a better kernel that goes with this rom?

  12. melvinjohn Adel says:

    Use or phone browser it works.. I also tried using pc won’t dload also

  13. Sol says:

    Hi Max, this rom looks fantastic. A lot of work went into this one.

    I havent got myself around the multiscreens yet but Ill get there. One thing I was surprised to see working is the stock FM radio!!! Woo Hoo, been on RR for too long and kinda missed the FM Radio.

    That 360 camera is awesome!

    Not looking back and I’m going to have this one for a while. Can’t want to show off to my friends~

  14. Rj says:

    Hey max link isn’t working… Please fix it

    • Sol says:

      Give Max a break, go a google it yourself! or check out the link at xda dev.

      Fark some people! Always expecting to be spoon fed.

  19. Danilo L says:

    Great rom, I prefer the classic stock icons, but the features of the SGS3 and Note2 are great. Battery drains faster than other previus roms i tried. Got a better kernell with overclock and battery save features?

    Really nice work. Thanks a lot.

  20. Olivr Palr says:

    I only have 1 phone, GS2, and I’m on Siyah dual boot with 1st Rom RR and 2nd Rom Rootbox. I tried using this as the 2nd Rom (I love RR toomuch), but, surprise surprise bcoz I can’t be arsed to find if Rainbox works with Siyah, no can do. Just as well, the icons in this ROM are fukkin horrible. sorry.

  21. Basil says:

    What did I do wrong?

  22. Locky says:

  24. Aditya Ladwa says:

    whatsapp does not connect even if i have a working data in my s2…. PS the apps are simply crap… otherwise a gr8 ROM …

  25. Harshvardhan says:

    Very good ROM.
    But woud have been best if Social Hub Premium and Samsung Apps would have been there.

  26. Darko says:

    Hi, I’ve tested the rom and it’s by far the best one that I’ve tried. Just has few bugs… When you listen to music and the screen is locked the volume rocker switches to next/prev song instead of adjusting the volume. But other than that this is by far the best custom rom ever. Big thanks to the developer, and to you for posting it here 🙂 l

  27. salim sayyad says:

    Please developer dude update this rom for better battery life
    Currently having 24 hrs stand by time.
    Thanks 🙂

    Thanks a lot to the DEVELOPERS for developing such a great ROM. Believe me my S2 is now NOTE II as far as user interface and functions are concern. Now I do have Galaxy Note II with new specifications like 4.3″ Super Amoled Plus Display, 1.2 GHz Dual Core Processor……
    🙂
    Thanks a lot to Maxx as well to provide the link…
    Thanks

  41. Michael says:

    Hey guys,

    have any of you noticed that with some of the new roms the keyboard will not auto fix mistakes or predict words for you while typing ? but in the other roms such as Resurrection Remix it will ?

    Do any of you guys no how to resolve this issue ?

    thanks a lot in advance !

  42. Hanis says:

  48. somesh sharma says:

    a quick question…

    are there some roms that come with kernels?

    and is it necessary to install kernel after installing a custom rom?

  49. Eran says:

    I’ve installed the ROM coming from official ICS after rooting, wiped every thing but still it stucked on the Android screen or on the Samasung screen. Please help!

    • shaquel says:

      To me this sound like the rom is not installed….or the kernel you are using is a stock or maybe your phone is not rooted…root it….then wipe data nd factory nd dalvik twice…then try istalling the rom again….hope this really helps

  50. Eran says:

    fully bricked my phone trying to restore from this ROM

  51. Mat says:

    what about the SGH-T989D ?

  52. Birdost says:

    It has been a few day since i started to use Rainbox. Firstly thanks for multiwindow. Thats the best property i ve seen on android. Also new camera is so cool. I get good results with benchmark tests. A few bugs there. When you click flashlight on toggle bar, it doesnt work. And very bad batterty life for me. It would be better if we had a chance to change icon on toggle bar. They are awful.

  53. Raviraj says:

    hi there,
    I was very very excited to download this rom but unfortunetly its giving problems…
    – the new multi-window/tasking thing doesnt appear on ma home screen…. after rebootin ma phone it came up once… and the second boot it didnt.
    – the camera 2nd camera has issues, it starts shootin on video mode but when stopped, the phone hangs…
    – the 1st camera also doesnt start at times…
    – the reboot system also doesnt work…
    – i have installed this rom twice… and i have gone a long mile to install it… first to get CWM on ma phone i installed a ICS rom and then through i updated it to Rainbox.
    very disappointed. 🙁
    I have cleared partion cache, data, dalvic… twice, but nothin…
    all the guys above donn seem to have a problem,…. please help!
    :((
    where am i goin wrong.
    goin back to 4.1.2 JB

    • shaquel says:

      Try fixing permissions..you can find that in recovery…and lol you have to hold down the back button or maybe it is turned off in the setting…search your settings…and turn it on….nd maybe you didnt install the rom for your model number….am just saying maybe..hope this helps

  54. Raviraj says:

    @birdost – agreed! the flash light doesnt work and the toggle icons are so tacky… not impressed by this rom.
    the previous JB rom is awesome in terms of battery, soothness and looks… I just wish it had the the “philz kernel”

  55. Atif Syed says:

    best rom till date
    Battery life is better than the resurrection remix
    Multiple window , popup browser , pop up play , ecosphere , direct call and all other motion functions are working flawlessly
    Now my gs2 is not much behind gS3 or note2
    customization of notification bar hav room for improvement
    all in all it’s a great rom
    thankyou

  56. Markús says:

    Hi, i had no problem downloading the rom. This is one of the best rom i have tried. I have tried the Salman rom, (Samsung base) Resurrection remix and the Thunderbolt rom. Allthough they have the ability to do a lot of tweaks, they do not have Samsung base. That means that you can not use the hdmi output, but on this rom you can. This rom breathes new life into Sgs2 Sammy. I have not found any problems yet, one small issue is some of the icons are badly done, but when the rom fast and works as well as this, it is not a problem. I recomend it higly. 🙂

  57. joseph says:

    Hey max a got a problem, i use this rom like 2 days and now my cell is laggy and dont respond well, i need help, i used to have Cyanogenmod 10, what i need to do to come back to cyanogenmod, thanx bro.

  58. Hanis says:

    I’ve lost everything trynna restore to my previous rom. But that’s OK. My phone is a whole lot faster now for some reason. Thanks for trying. Anywhore, this ROM is quite nice but I really hate the icons for the Wi-Fi and all. Sure I could metamorph it to something better but neh. Waste of time.BUT THE MULTI VIEWER WAS SO AWESOME OMG I CAN’T WAIT TILL THE REAL DEAL! I was planning to get a galaxy note 2 cause the update for s2 is taking forever. But knowing that’d there will be a multi viewer changes everything.

  59. Hanis says:

    Also the battery sucked . So good luck with that you guise.

I tried to instal other versions of rom’s but after instaling them i get always boot lop and i’m forced to instal back the leaked version of jellybean an it always locks my sims after instaling it back… PLEASEE HELP MEEE (mike_CJ_X@yahoo.com)

  66. Darko says:

    After using it for about a week.

    DO NOT INSTALL THIS ROM
    1) Battery drains like crazy
    2) Constant touchwiz bugs, you cannot press anything
    3) When listening to music, volume rockers change the song when screen is locked, instead operating the volume
    4) Did I mention battery drain ? Like, really, really fast battery drain !

    Rom is cool, but it has too many bugs to be usable.

  67. erick says:

    I my phone rooted about some months ago and had to unroot because of some problems that occurred. and now i wanted to install this ROM. Please with all the steps that i need to follow. i am not perfect in this. so please comment.
    thanks.

    • shaquel says:

      Easy…just use odin to root your phone again…odin will install both supersu and cmw and rom control.download the rom to your sd card..go into rom control…you can install it right there if you buy the full version (rom control) but if not click reboot into recovery…then you nay backup that rom you are using…after your done go right ahead into wiping cache data/wipe factory and you may go into advance and clear dalvik cache if you like…after that go back and go into install zip.choose install zip /from whichever sdcard you placed the rom in/ and install it…nd your done..just reboot…but before all that..download titanium backup after you root it and back up your apps..  hope you appreciate…then download titanium from play’ and reinstall your bAcked up apps…

      • Raghav says:

        Hi Shaquel,
        it’s appreciable that you replied.
        first of all, the last time i rooted my phone i actually soft bricked my phone because i did not choose the .pit file included in the package. i am a little confused about the kernel version. the tech guy after unrooting my phone put the kernel (in the previous comment) into my phone.
        so do i need to flash another kernel or do i just need to do the same thing i did before?
        and does your phone need to be rooted to flash any kernel?
        and also that this ROM isn’t downloading. i downloaded 414 MBs and then it just stuck.

        • shaquel says:

          It depends on which kernel you are using….if its stock kernel, no root would be necessary but in order to use a custom rom you need a custom kernel..so just for surity nd safety….try this….IF YOUR PHONE IS ROOTED download 2 files../rom you want to install/dorminax latest kernel/ and place them on your sd card……Do the drill for installing a brand new rom…wipe/reset etc…..then install zip ‘Dorminax kernel’..Do not reboot as yet …then install zip ‘rom’……then restart and this time please make sure you download the correct rom for you Model Number…whether Gt i9100. Gt i9100G etc….

  69. shaquel says:

  72. Didine says:

    Hi max, i have sim locked after installing this rom, can you help me to solve it ?

    • Ken says:

      Use an app called galexsimunlock from the Play Store. I tried the other free apps but they did not work for me. It’s pretty inexpensive so I recommend it and its straightforward to use. The powermax app too its really useful and not too difficult to use.

    HEY PEEPZ II GOT A BIG SURPRISE….. V8 is out like since 10 days ago but blahhhhhhh… Here’s the link amma go put it on now 😀

      hey rakeeb..try to wipe or rest to factory setting, wipe dalvik and cache for that..mine works just fine..but only the usb is making a ruckus..hehe..but i can live with that..with no fuss..try it n have fun with this awesome rom!

  82. Keegsconte says:

    The Rainbox ROM brings many things to the table. A lot of Eye Candy, Multi-Windows, Spherical Camera, The Popup Browser, seems quick and snappy. But I don’t feel as though this would be a daily driver as there seems to be Wi-Fi issues or at least with my Bell GT-i9100; there is also issues with Syncing to Google accounts, email and contacts seem to make their way fine but Pictures are just not happening. Good Rom but needs some work and possibly not so much B-ling.

  83. zaheer says:

    it asking me for sim unlock code. my phone is unlocked

    • Victor says:

      So is your phone locked or unlocked? I also have the same problem and its locked

      • Xtgib says:

        I also had the same problem, when I first got my phone I knew it was factory unlocked from Samsung but when I wiped my cache and data and flashed over this rom I got that SIM unlock code…searched for a full 2 days on apps and different programs that could get me my unlock code but sadly everything cost money lol at the end of it all I ended up going into a cell repair shop explaining the problem and him fixing it in less than 10mins and charging in $20 to re-unlock

  84. John says:

    Rainbox ROM doesn’t exist anymore ..it was taken down from XDA ….the developer never asked permission to use code or give credits to original developers ….so its advised to uninstall since there is no more development for the Rom

    • Xtgib says:

      no way…its been giving me alot of issues with apps force closing and crashing…thanks for the heads up about it being taking down

  85. sfdsd07 says:

    it was a good rom anyway..i just cant wait for the updated version but its doesnt matter anymmore. Such an awesome rom the dev came up with though

  88. biep99 says:

    installed this rom and really like it.just had an issue with my gps fix, which didn’t work anymore with my navfree gps app. bothered my so much. read about the fix in a nexus forum which did the trick. just disable google locations in settings and reboot the phone. re-enable it and gps is fixed in a few moments. thought the bug was due to the rom, but as it seemed, it wasn’t. thought I could help anyone posting it here…worked for me 😉
