Dual boot. - Galaxy S III Q&A, Help & Troubleshooting

Hey guys,
I want to know how i can dual boot 2 roms in my phone. I'm kind of a noob. I have a Samsung galaxy s3.. And I've had some experience with rooting. Currently on paranoid android rom and yank555 kernel. I want to know if i can dual boot 2 roms such as omega and paranoid android. Any help or info would be appreciated. Thanks a lot.

But remember, Siyah kernel is for stock and CM10/10.1 ROM, it may not work with AOSP/AOKP ROM?

No a custom custom kernel will not remove your ROM, before you flash your chosen kernel read the devs instructions and notes on the brick bug issue. I use the latest siyah have had no problems. Read before flashing there is no rush. All the best

Nope it shouldn't brick your device but Instead of using Odin why not use the safer CWM recovery?

please rephrase your post. It's not clear

He meant stock Samsung kernel.
OP: you can't do this, since CM9 needs kernel compatible with AOSP ROMs.
Then is there any way to remove cm9 rom?
Sent from my GT-I9100 using xda premium
If you want to remove CM9, I am assuming that you wish to replace it with a new ROM. Go through the forum and choose a new ROM and place it in your phone's USB drive or SD card. Then go into ClockWorkMod Recovery mode and Factory Reset/Wipe your device. Then install a new zip and choose the zip file of the ROM you downloaded. If there is any part of this that you do not know how to do, say so and I will give instructions or refer you to one of the many excellent guides that have already been written.
A kernel is essentially only a part of a ROM. So when you flash a new ROM you are flashing a new kernel as well, but when you flash a new kernel you are only changing the kernel section of your ROM, not your entire ROM.

Custom Kernel for Novena Rom

hi, wondering if there is or what custom kernel is compatible with the Novena Rom to overclock with? thanks in advance...
There isn't one. Stock kernel is the only one at the moment. This also goes for black star 11, padawan 6.1-2, and any other rom using the new base.

Yes it will he is working on it.
i read somewhere that if you want cm 10.1 as your second rom you have to install it as you first, primary rom, and then swap or clone it to second rom (ofc you need to backup first your primary rom).
I wanted to test it but i dont have time... but maybe it will help you.
yea

Dual boot cm9? Ics? Are you sure thats possible? Don't both roms need to be JB?
Why would you want to dual boot cm9? 10.1 is the latest
Sent from my GT-I9300 using Tapatalk 2
Both roms need to be jellybean at least, so you will have to use at least cm10...

Doesn't it depend on the version of the Siyah Kernel? Maybe I was wrong

ICS was never supported for dual booting. So no, you cannot.

Hey go to googymax2 thread or to devil2-kernel thread. Read everything carefully ......A How to is written there.....But i wouldn´t
use a stock rom as first or second rom. I had a dualboot with devil kernel 2.3.2 istalled / the devil recovery. As first rom i had a cm11 rom and as second rom an SlimRom and everthing was working well....Try it man it works.:good::good::good:
