[Q] Dual booting roms, don't have the option? - Android Q&A, Help & Troubleshooting

Hey people!
I've just got a few questions in regards to dual booting roms on my device (Gs2 i777 running Dream Kernel 2.7.4.) So yes, I'm a bit new to the world of rooting, but I'm eager to learn.
Anyway, I'm looking to dual boot roms. As of now, I have the CM10 nightly build as my daily driver, which is nice. I've got Jelly Bean running as well. But when I boot to recovery, I no longer have the Dream Kernel boot up screen, which provides the option to dual boot, which is what I'm looking to do.
Do I need to get off CM10, go back to my back up, and then set up the dual boot from there? Or can I set up my dual boot on the CM10 mod?
Thanks in advance!

MIUI ICS v 4

Hey guys, I have managed to setup MIUI v4 on my SGS2 with success and its brilliant.
I have two questions, first I feel the ROM is a bit sluggish at times, is it a kernel related? cuz it says my base band is LPQ and the software is based on LP7 ?!
I tried flashing different kernel LP7~LP3 and didn't work out, and got boot loop.
Second, is there anyway to enable Screen tone in video layer like in Samsung stock ROM? thx

dual boot

are we able to dual boot? like say i wanted to keep my gb rom but wanted to mess with the ics rom sometimes... also i heard you can install froyo on an ipod, does that work both ways?? that would be an awesome dual boot if so...

How to create Dual boot with Stock 4.0.4 ICS??

Guys,
I have been using codecROM for the past one month and i felt it was Superb. but i'm a viber user so viber isn't working on codecROM 9.1 so i had to revert back to stock ICS ROM. i have seen few posts regarding dual boot in Siyah Kernel. what i wanted to do now is as follows:
1st Boot: Stock ICS 4.0.4
2nd Boot : Any other custom ROM
is this possible..??
Currently my phone is Fully rooted.
also suggest me any ROM in which apps like viber which use wifi for calling will work for sure..
Thanks a lot guys i have learnt a lot from xda-developers

my bad ... sorry guys.. just now i came across this thread.. http://forum.xda-developers.com/showthread.php?t=1709686 so according to tht dual boot is not supported by ICS... what if i update to 4.1.1(jelly bean)?? then how to dual boot??
Once you upgrade to jelly bean you will have to install siyah kernel, the latest version to be able to dual boot. Read through the siyah kernel thread under original android development, it'll explain everything.

Dual Boot on S3 I9300 Change 1st ROM

Hi,
Should be a fairly easy quick question
I'm running Siyah 1.8 Kernel on my phone to have dual-boot, which I really like as I can use a lightweight ROM for gaming and things and also have my stock features to hand as well.
However have decided I have tired of Stock and would like to use CyanogenMod JB 4.2 as my primary ROM and stick with my current WanamLite as secondary.
Are there any issues with flashing a new Primary ROM with CWM and keeping the 2nd ROM as it is?
Thanks

The Siyah thread gives you instructions on how to flash CM 4.2. If I remember well you can only have it as 2nd ROM (??). If so, than you can just select in STweaks to boot always into 2nd ROM for instance. To keep your WanamLite version, just swap 1st & 2nd ROM.

[Q] Dorimanx Kernel + Neat ROM Lite 4.0 refuses dual boot

Hi everyone
My issue is somehow strange, I performed a clean install (full wipe, etc..) with Dorimanx Kernel 7.43 of Neat ROM 4.0 (XXLSJ) as primary ROM
When I install secondary ROM, Neat ROM boot loops and get stuck on the first Samsung bootanimation (where the logo is being drawn again and again)
I fixed permissions for secondary ROM, but still no boot, neither primary, nor secondary
I thought that ROMs are independent but seems like I'm wrong
Now I'm hesitating to retest the same with 7.44 kernel and 4.1 ROM (XWLS8)
What Have I messed ?
PS:
I reflashed my ROM and my phone is working fine, this thread is not about solving bootloop (with hundreds of threads dedicated here), it's about dual booting
Dorimanx doesn't support dual boot with any Samsung jelly bean roms currently
So it's kernel related, I did not notice this detail when flying over the changelog or the infinite number of replies :silly:
Thank you for the quick answer...
Try this Siyah MCM Kernel ver 3.0.60
http://sourceforge.net/projects/cm10i9100vsync/files/kernel/
I believe it is smoother than the Dorimanx Kernel and it supports dualboot.

Not exactly sure what Conny has posted, but just incase you didn't know dual boot can't work with any siyah or dorimanx kernel till the dev fixes it, and only siyah 6 beta 1 or above and dorimanx v3.37 or above work with samsung jelly bean

1Chef is right, I thought Neatrom published a 4.2.1 release
Considering neatrom is based on stock Samsung and not aosp then it can't have released 4.2.1
Got another bootloop while trying (hopfully) the new setup (7.44 + 4.1.2 XWLS8), nothing happened
I think that siyah will give the same result as Dorimanx is forked from, maybe with latest stable future release of Siyah, it could be fixed.
Now, I got tired from re-re-re-re-reflashing my phone :silly:
I'd better wait
Newbie Takes The Plunge to Custom Rom and Kernel: Any Suggestions?
I'm still fairly a newbie, but have rooted two phones so far, thanks to the great information, tutorials, guides, resources, and videos posted here on XDA. I have a Samsung Galaxy S2 GT-I9100 and my daughter's Samsung Epic 4G.
I rooted my I9100 successfully a few months ago, but have never flashed a rom. I'm going to try out Neat Rom Lite tonight. I've finally gotten up the nerve!
QUESTION: Does anyone have any suggestion of which kernel I should flash along with it? I need better battery life. I would love to be able to watch videos and use the phone regularly and make it through the whole day without charging. Is this possible? Can a kernel and Neat Rom Lite do this for me?
Also, I rooted the Samsung Epic 4G yesterday. Any suggestions on what rom and kernel to put on it and how would be greatly appreciated.
Thanks a bunch for any assistance and comments.
