    V .4.0.1 doesn’t give me the option to dual boot with CyanogenMod X-TremE CM10 Beta .
    It also doesn’t give me the option to answer the phone hahahahaha lol .
    My wife rang me five times at work and I couldn’t answer her , damn it was good ,and very funny lol lots .
    In the end ,after I had stopped crying laughing , and could finally get up off the floor , I sent her a text , to text me.
    None of the physical buttons worked , nor the stupid bloody on screen button , and it felt soooooo good to hang up on my wife five times , and have a perfectly valid excuse LOL .
    Truth IS stranger than fiction , and this was funnier than any joke I have EVER heard .
    After over thirty years of mental torture , I got one back , and , I didn’t even have to try hahahahahaha .
    I’m past help now , ( I’m going straight to the laughing academy ) but could you please help me answer the phone LOL , and tell me how to set up or find dual boot in the bios , because the option was there until I loaded X-TremE !.
    I have enough experience at building computers and installing Roms on phones to know what I am doing .
    Your help will be much appreciated
    Thank you .
    Glenn .

    Hi, So I have just rooted my samsung SII GT-I9100. It is still running Gingerbread and I have also backed up using Titanium so I’m sure the root is working. I would like to get the latest kernel on my phone, and then get the latest version of JB. So my main question is, what kernel can I install if I’m using Gingerbread???

    Thanks in advance for the help,

  12. Slim says:

    I have the older version Siyah Kernel v.4.0.1. Are there any certain steps I should take before flashing this kernel. I ask this becasue I already have two ics roms dual booted. Therefore must I delete one of my roms ( so im no long dual booting) before i flash thde new Siyah Kernel v.4.0.1 or can I just flash it with the new one and it would automatically keep my two dual booted roms without conflict?

  13. Slim says:

    Can both one ICS rom and one JB rom be dualbooted together at once with this curretnt version?

  15. Niklas says:


    I made my old original ICS 4 ROM as 2nd ROM.
    Then I installed CM10 ROM as 1st ROM. Then the kernel was overwritten to… so i can’t use dual boot.
    Then I installed Siyah Kernel v.4.0.1 again.

    The boot up menu with countdown then comes up again and it works to press home button and start the original ROM. BUT the CM10 does not start when just wating… =(

    Im a rookie on all of this, but did I miss anything? Doesn’t CM10 work with Siyah??

    I have got this kernel and installed it on my s2 via Odin. After getting auto restart, my phone gives yellow triangle beneath the samsung image. Moreover, Syah kernels logo appears on phone and it lasts for 4-5mints. After that a new screen appears with the Android image by saying Kernel Panic Mode (something like that) and nothings happens further..! I am stuck in this situation and it creeping me out..!
    Best Regards,

    Sea of information from this site, awsome job you guys are doing.

    I tried this kernel for i777 and the back button is not working. Also its not able to boot into the second supernexus jb rom. No complaints, I just tried the unintended! Any plans of it to come out for i777 and support for second jb roms?

    This doesn`t work on JB 4.1.2. Tried with stock and Rootbox ROMs. Galaxy S2 won`t boot, but when using CWM to flash backup firmware, it shows Siyah CWM interface with touch screen navigation.

  29. Nadeem says:

    Hey guys I have a galaxy s2 gti9100 and it was on stock gingerbread 2.3.5 so I rooted it using the speed mod kernel and then I installed the Cm9 stable version. But with cm9 or any other ics rom my battery drains too much during night and while standby. Any suggestions how to overcome this problem?? Moreover when I turn off my phone during the night and when I turn it on in the morning the battery drains almost 25%!. So does flashing the latest siyah kernel help me with battery issues and if yes how do I flash it?? will it work for CM9 stable version as I don’t want to move away from cm9.

    • Nadeem says:

      I flashed the zip file via cwm and my phone wouldn’t boot! The screen would just give a faint white flash so I had to go into download mode and then flash the speedmod kernel again after which I had to reinstall the cm9 stable rom. I thought I had bricked my phone :-(. And now I am scared to flash this kernel can anybody tell me what is the correct way to flash this kernel with cm9 stable on board. Thanks

    Any help?

    • dave says:

      I have rooted 4.0.3 siyah 5.0.1 runs ics on both roms fine but I cannot get JB to run on second rom.
      Tried multiple tutorials best I can get is looping “unfortunately, process has stopped” error.
      Have tried spanish official 4.1.2, (worked but had to wipe ics rom 4.0.3 as it was not upgradeable, wouldn’t dual-boot with 4.0.3 intact), jellybam=no boot at all, slimBean=unrecoverable error or endless logo screen.
      Can anyone confirm actual running ics / JB setup?
      Spent hours on this, very frustrating!
