Dual booting - Galaxy S II Q&A, Help & Troubleshooting

hey guys, just signed up so please excuse my ignorance if this has been answered, redirected previously.
ive been using slimbean as my daily driver and love it without any problems. but for work i require something with slightly better battery management hence through my research it seems like 'ressurection remix' rom would be a good bet.
i currently use a s2 i9100 and wish to dual boot slimbean (as main) and ressurection remix (as secondary).
i understand siyahs latest kernel has issues with dual booting so with perhaps the older one 'SiyahKernel S2-v5.0.1', my question would this be possible ?
or perhaps a different kernel... again.. this is new to me and i would appreciate any direction or advice. i appreciate dual booting is always under construction...
thank you..
*zem
(would prefer a response before i start flashing stuffs, please dont question the why but i am seeking the howto)

unsucessfull
flashed siyahs latest beta kernel following the instructions....
flashed kernel.
booted cwm
setup second rom
installed second rom
reboot
home key, selected second rom... blank screen.
not working for me. ( if that had of worked i was going to swap first and second roms because after installing the siyahs kernel slimbean failed to boot. (blank screen after siyahs logo).
will try previous version..... i believe if this fails i will have to wait for siyah to 'fix' dualboot as is said in his latest beta. please correct me if i am wrong.

To be able to boot 4.2 and 4.3 you need dorimanx kernel. That would be 9.xx version. For JB 412 you need 8.4x version. Dorimanx is the kernel to use IF you dualboot newer Roms.

first flash siyah latest v6.0b5 and then flash the latest dorimanx kernel using the cwm.
Dorimanx is the best bet and would easily dual boot the roms you mentioned
Flash the latest dorimanx kernel v9.43 and you wil be good to go
Gud luck mate

awesome kernel
guys. dorimanx kernel worked perfect. flashed it, booted it.... installed resurrection as second rom.... thank you so much.

[Q] should i must have to change the kernel if i change the ROM?

hi guys,
i wanna ask you senious guys that,should i have to change the kernel each time if i want to change the ROM of my galaxy s II or any kernel will work with any ROM?
kindly assist me in this matter.thanks.
What type of Rom are you trying to flash?
Most custom roms include a kernel so you you will have to refresh back to your preferred kernel.
Or you can open the zip file and replace the kernel of your choice as long as it matches your firmware version, ie GB kernel for a GB rom etc.

let me add the screen shot for your help.it might shows the ROM and kernel and suggest me the best ROM and kernel for my galaxy s II.and tell me which ROM and kernel is best for battery life cause this kernel and ROM is just crap and sucks the battery.

any kernel may not work with any ROMs...almost all samsung firmware versions has got its own versions of Kernel.
In SGS2 normaly custom kernels are used for rooting your phone, like CF-root, whcih are made for almost all the samsung firamware matched kernels, you only want to pick the one matching for your ROM.
It is also seen sometimes advised to back up your Kernel, this can be done using a tool from Market called "Ktool", at a worst scenario, when your installed custom kernel giving you a treble you can restore the previous one.
EDIT : you are already on a custom ROM as well as Custom Kernel. both have got their newer versions alredy.
checkrom is now on V6, and Siyah kernel is now on v2.6.14
Well your still on gingerbread and an early kernel and early checkrom. There are many roms and kernels you can try the best for battery life us what works best for you and only you can figure that out with testing.
Try out an ICS Rom if you haven't done so already and there are now custom kernels for that as well.

On xda there are many roms with included kernels. Resurrection Remix v1.1 is my personal favorite ICS rom at this moment, with stock kernel battery life is very good. Just search on xda

I meant the kernel that is already included with the rom when you flash it. So just flash the rom and you don't need to install another kernel after it.
Here is a link to the Resurrection rom:
http://forum.xda-developers.com/showthread.php?t=1436854
Hope this helped you
If you flash a rom it replaces the kernel you've been using with that of the rom you're flashing...
Soooo
Eg cm9 + siyah
If you flash a new nightly it'll replace siyah with cm9s kernel so you have to flash siyah each time.
Think that makes sense..!

[Siyah Kernel] Can I dual boot an ICS ROM and a JB ROM?

Title said it. I want to try out the new CM10 builds for the S2, but I still want to keep my stable CM9+Siyah build running in case the new ROM has some problems. Went to the Siyah kernel dual boot guide thread, and it's stated there that one can only dual boot 2 ICS ROMs. That means no ICS+GB... but is ICS+JB possible?
By the way, yes I did do a search before asking and found this thread http://forum.xda-developers.com/showthread.php?t=1800866 where a method is proposed, but it requires switching to another kernel and I'd like to stick to Siyah.
Current configuration: CM9 RC2, Siyah v3.4.

cooool! thanks for the info, nice question by the way to the OP

kernel doesnt matter u can run ics and jb with nearly any kernel also doing it
Yea you can dual boot with JB and ICS, just not GB.

noob question number 5

ok guys
am having isues dual booting
installed syrah kernel fine and used STweaks to set up 2nd rom
am using a cyanogenmod 10.1 version as my 2nd rom
but it just boots into the cyanogen spinning logo - and goes no further!?
is the 4.2.1 not compatable?
thanks guys in advance
I'm not sure
After install 2nd rom you have to flash siyah kernel is it OK this part?
Sent from my GT-I9300 using Tapatalk 2
yep reflashed the kernel
You will need to find out what Siyah kernel you are running as not all support dual boot.The latest version s3-v1.8.8 is meant to work with dual boot and has cm10.1 support.Check it out and download from here.
http://www.gokhanmoral.com/
Dont forget that after installing the second ROM you will have to re-install Siyah cos the secondary ROM probably wont have the correct kernel.Also a 4.2.1 ROM may need a different Siyah version than a 4.1.2 or a 4.1.1 ROM and this could also be the problem if you have 2 different firmwares running.
When on dual boot you have one kernel controling both.
ok that makes sense
have siyah version s3-v1.8.8 already running
reinstalled siyah after 2nd rom installation
still a no go
thought the siyah kernel was 'one kernel to rule them all'.......
or so it says.........

If I remember from when I dual booted a second ROM I had to full wipe install it.I imagine that you did but you could try and pass your primary ROM to secondary and full wipe install the new one.Then just swap them over again so the full wipe primary goes to secondary and the one you passed to secondary will come back as your main ROM.....if you get what I mean.Kind of a wierd explanation:silly:
The boot problen is definitly to me a kernel issue anyway.
yeah - will do the clone/swap thing!
by the way
are you part of the omega team?

[Q] Could I set up dual boot using Siyah kernel V5.0.1 with CM9 and JellyBam?

I know we can set up dual boot using Siyah kernel but this time I want to know can I flash a JellyBam ROM as secondary while using CM9 stable for my GT-I9100?
What is the process to install the secondary ROM without messing with my primary ROM as there is a lot of data on it.

1) u have to check whether the Jellybam version ur trying does supports Siyah kernel v5.0.1 for now ma8
2)u have guides related to Dual boot which u can search on XDA.

I checked on Siyah kernel's official site but there is no mention about JellyBam ROM. Gokahn has just told about JB+ICS nothing else more much could be helpful for me.
I have read guides for dual boot but they are so simple as I'm looking for but yeah I can manage. I'm looking for a simple guide if anyone can refer or post for me.
One more question how can I increase charging speed of SGS2 using Siyah kernel?

[SOLVED] PAC Man ROM + MIUI on dual boot + Siyah kernel = bootloop

Hello.
So this is my problem.
I'm trying to flash the PAC Man ROM then flash Siyah Kernel v6.01 Beta 5 version, then flash on dual-boot options MIUI v5 version, and the same kernel, everything through CWM. When I reboot my phone to primary rom I get the SAMSUNG Galaxy S II logo next Siyah Kernel logo and then black screen When I try to boot secondary rom ( MIUI ) I get the MIUI logo and the startup sound but the sound is cut off and then I stuck on this logo I saw at youtube when one guy flash AOKP and MIUI together on dual-boot on siyah kernel too, but I can't Can you help me ? Please.
Sorry for bad English I'm from Poland.

How old was the video that you watched? The problem is due to siyah not being updated for the new Mali drivers. These are required to boot PACMan. If the video was a little older, it's likely these new drivers hadn't made it into PACMan yet, and hence Siyah booted it up.
I can't tell you if MIUI is compatible with this, but try dorimanx kernel. It's originally based on siyah kernel and is capable of dual-booting. I only can't tell you if it will work with MIUI as I've never flashed MIUI. There are two versions of the kernel, the 8.xx branch and the 9.xx branch. Read up on which one you'll need for MIUI, although I can tell you that both the 8.xx and 9.xx branch will boot PACMan.
Edit: and your English is great, don't stress

Yeah, it works I just flash Dorimanx 8.35 and I have worked MIUI on primary rom and PAC Man on secondary. I just wanted to test MIUI but its no problem right now And the video was made on ICS Siyah
