[Q] Dual booting two different Custom Roms GT-i9300? - Galaxy S III Q&A, Help & Troubleshooting

I tried today Dualbooting Omega v27.1 as primary Rom and ParanoidAndroid JB as secondary rom and it worked perfectly.
Now i tried the same primary rom (Omega v27.1) and HyperGalaxy,Hyperlight,and some other small lite rom,none of them worked instead Blackscreen loop.
So my question is ; can i Dual Boot my Omega v27.1 with foxhound or Wanamlite or any other custom Rom,or this is just incompatibility of Updater Script from EveryRom??

Hi, it is possible, but you have to format 2nd rom wipe cache and davile cache.

Either ask this question in q&a thread or atleast in the related siyah discussion thread.

gb? you mean ics roms! there is no gingerbrad rom for s3
and yes. newest release of shiya are only compatible with jelly bean rom's. it's better way to copy 1st rom to 2 rom directory by using the shiya 2nd boot utils an flash the other rom as first rom using normal recovery.
must flash shiya again after flash of any romwithout shiya included!

Space and Time Rom (With dorimanx) + second rom = bootloop?

I have got an sgs2 (GT-i9100) and use cm10.1 nightly from 13.01.13 with dorimanx kernel v7.44. This kernel gives me the opportunity to have a second rom. So I decided to install a rom with touchwiz called space and time v2.6.0, because it has some cool and useful features. But after installing as second rom I landed in a bootloop with these ugly starships.
So I tried to install as first rom after making backup of my cm rom and everything worked. Now I just had to restore my backup as second rom. I did and... Dang! Space and time in bootloop again, but second rom (cm10.1) worked.
I thought the restore causes the problem. So I started from the beginning first cloned my first rom (cm10.1) to second rom and now installed space and time as first rom. But now I had no more second rom. I think that happened because the s&t installer installs dorimanx again.
So my question is: What did I do wrong? (maybe my mistake is, that I didn't fix the root, like it's said in the installing introduction after flashing, but I cannot find the that option in cwm). Does somebody have the same problem? Or am I just to stupid?
Thank you for answering and forgiving me my bad English.

Factory reset between different roms, and cache wipes, including dalvik.
AW: Space and Time Rom (With dorimanx) + second rom = bootloop?
I did. Same results. It's strange because I have heard that the different roms won't touch the other in a video. But here it seems that doing something in second rom leads to a bootloop in the first rom.
Any other tricks?

I also tried with another rom and same results again. Maybe dorimanx is the problem. I'll try with siyah

I did a quick bit of research.
"NOTE: This kernel is for AOSP / AOKP / JB-AOKP / CM9 + CM10 + CM10.1 / cMIUI (Only) / Sense 4 All / SAMSUNG ICS + JB Stock ROMs (The JB Leak XXLSJ it's supported from v7.37, JB Official XWLS8 supported from 7.44)"
If i understand, they both use the same kernel though...On galaxy sii root, it says at the start of the video "please do not flash [touchwiz s/t] on anything other than your INTERNATIONAL galaxy s ii... But then you say you've tried another rom with no success.
Thank you so much
ok, so dorimanx does not support touchwiz roms in dualboot mode? it works if it's the single rom and there's no second.
I already talked to someone who wrote the space and time thread in xda. He said that someone is making it working. I have also read a thread in which XWLS8 is the problem, but i cannot find the thread now.
I found the thread: http://forum.xda-developers.com/showthread.php?t=2120514
I had no time to try the long way yet, but the second way with the modified updater-script.zip did not work.
From that quote, it does in fact look like dorimanx supports touchwiz, which is a samsung ics or jb rom. Do you have an international version of the sii?
AW: Space and Time Rom (With dorimanx) + second rom = bootloop?
Sorry i don't know exactly. It was originally branded by tmobile Germany (modem was i9100BOLP7 I think)
I have got a screenshot of pda, phone and csc stuff I made before rooting, but uploade doesn't work.

dual rom boot?

how to make dual boot roms on international s3
You cant make a dual boot rom. But there are dual boot kernels which you flash yourself and then can install a second rom aswell. I dont know which kernels do this but there is one or 2

I advise you to install Siyah kernel 1.9 it's let you combine 2 rom's personnaly I installed in First Rom a Samsung based rom like WanamLite; and in the second rom I install the latest CM 10.1 it work perfectly . however I still have issue after changing from the WanamLite Rom to the latest Omega 44.4.
My phone crashes after the first Boot. I'm working on it

Quick Dual Boot Question

Hey Guys, Im coming here and well modifying my phone after a long time..I have forgotten few things and just want to reconfirm 2 things about dual booting(as i want to install a new rom side by side). My current kernel is siyah 6.0vb5(the last beta produced for s2). I currently have alliance rom v9 installed which is based on 4.1.2. SO:
1. I wanna dual boot omega rom v24 which is also based on 4.1.2. I can do this dual booting legally right on my siyah kernel version?
2. How does the internal data storage work in case of both the roms? For example, i play temple run on first rom as well as on second rom, so will their save data be saved separately or will be shared?
Thanks for replies in advance
1. You cannot dualboot any jb 412 rom out of the box. It has to be modified but there are modded Roms ready to download. Dorimanx is the kernel for dualbooting jb Roms.
Here you find lots of Roms already prepared:

2. I think they have different data if they dont link to a server.

Not even if my first rom is a custom rom? Alliance rom v9 currently..
Edit: ok i got it, but i jist have 1 question now..For dual booting, should my second rom be dualboot modified or the first rom? or both?
If you want two jb roms both need to be modified since 4.1.2 uses preload where your second rom would be. If you have a 4.2.2 or 4.3 you dont need to mod it since they dont use preload.
In short: if you want alliance as first rom you must download it premodded and install it. Then you install premodded neat as second rom. If you would use cm aokp or pa rom you dont need to mod it. It works as it is.

Ok so u mean to say if i want to install Resurrection remix 4.2.2 as second rom,i can install it as it is right? No need to have either alliance modded or RR moded?
No you cant. Your alliance( IF not modded) is already using preload so you will probably mess up things. There is alliance v9 modded which i used as second rom. Works well. Dont know IF you can get ota downloads though.
I guess you have to backup your data with TB and wipe your current rom(make nandroid first) and install modded alliance. Make sure it works both as first and secrom first since with the thread i linked before. I always use 422 , 4.3 in first and 412 in second, because at first there wasn't 412 for first ROM so it kind of stuck. RR you can flash as it is. No modding needed.

Ota doesn't work on modded alliance rom. Also a good man to talk to would be @Troubadour666 check his links out. Dorimanx 8.xx Imo is best for dualbooting.
