If you're talking about touchwiz roms, you might want a larger partition size to really make it usable.

What did you edit to change the image sizes?

I did it all from my phone using Root Explorer
-Unzip the multiboot setup zip
-Open the file named "create_images.sh" with a text editor
-At the top of the file you'll see the commands that dictate the image sizes, change these to whatever you like (in MB).
-Save the file and re-zip the contents
-Flash

This toolkit is designed to boot CM9 with a modified kernel initramfs. Even if you increased the images sizes to hold a stock rom, it will not boot a stock rom because the stock kernel uses a different initramfs.

It is possible to adapt the toolkit to boot a stock rom, but currently is not supported.

So, I've been working on trying to port MIUI to the SGS3 using CMTeamEpic's CM9 build as my base. Considering the kernel will be unchanged, would I be able to boot the ported MIUI using these multiboot tools?

Also, are there plans to develop this to be able to multiboot multiple (>3) ROMs based on any kernel?

Alright thanks for the answer, it would be really EPIC if that was possible. but i would definitely push for it, maybe a dual boot with a stock kernel on both that would be modified of course

Yeah, I suppose if it's using the unchanged CM9 kernel, then I think a MIUI boot would work. Just have to be careful with your updater-script. Fakecwm looks for certain commands to make sure everything gets directed to the disk images. Use the CM9 updater script as a guide.

You can see from our Development Plan that we intend to provide a Stock Boot alternative once CM9 is further along in development. Alternate 3rd-party kernels need to have kexec support before they will work, but they will otherwise "flash" with the current toolkit provided the updater-script is using the correct command.

**Keep in mind though, that the toolkit is designed to work with the official CM9 update zips and the flashing of any other zips is at your own risk. Issues encountered with alternate zips should be taken up with the creator.

I am really digging the dual boot! Especially for flash happy people such as myself. Many thanks and keep up the outstanding work!

Increasingly useful tool: just used it to install JellyBean!

Although CM10 is not yet supported by DualBoot + FakeCWM, for those of you that may be interested, here is bbelos' link from the CM10 thread:

This tutorial shows you how to modify the cm10 zip so it'll work on dualboot.

THNX again EPIC CM Team!

My unofficial file and directions for a CM10 dual boot are here

I can 2nd this issue. Talk/Google Search/Play Movies and one other all forced close on the dual boot of this. I followed all instructions step by step. Also lost root. Hoping it was safe to flash teamepic root v5 in red cwm because it did the trick.. Just wondering what I need to do to get my gapps working properly. I miss Google Now

Edit: actually super user force closes on me

You flash 'modified cm10' + standard gb GApps only in red FakeCWM, NOT root. Otherwise erratic behaviour like what you're describing. If you didn't modify cm10, don't use dualboot.

Try booting back to cwm5.5.0.4, then back to your stable ROM.

Delete your dualboot folder, then try again from a clean dualboot/fakeCWM flash for new images (then flash modified cm10.)

I actually did all that. Flashing gapps is just not working as expected

same here. i followed the directions correctly. all in fake cwm. maybe i should just retry, or just give up. i wasn't using it as a daily, but i kinda wanted to play with google now a little bit. As soon as this is more stable, ill boot it as my number 1 rom.

Have you DL'd noobnl's updated CM10? Perhaps you have a bad GApps dl?

Were you able to get CM9 going using dualboot? Since jellybean is in initial stages w/ buggy behaviour + NOT supported by Dualboot/FakeCWM yet, I would try & see about getting a good solid CM9 going.........THEN grab some fresh DL's + go for the latest noobnl release.

I had these exact problems. I attributed it to running out of room in the created images for the dual boot. So I modified it to increase the partitions. Worked like a charm for me. Give me a min and I'll upload mine.

Awesome, I started to figure that was the problem because everything works fine when not dualbooting. That would be greatly appreciated.

Ok. Here is the download. http://d-h.st/r3Z

Same install instructions as the OP. I would start fresh by deleting the /multiboot folder from your internal sd card. I have also included the boot_cm10.zip for booting into the rom, into the zip. I havent tested that yet so if it doesnt install it to the cm9 folder, just pull it from the .zip and put into the /multiboot/cm9 folder. Ill keep checking back if you guys have questions.

The new image sizes are:
System - 600
Data - 700
Cache - 200

I was gonna try and create a triple boot but it didnt work. I had it create both a cm9 and a cm10 folder and put the necessary files in both but when it went to try and getting it to boot the cm10 rom, it wouldnt. I am assuming there are more things I needed to edit in the image files but I am not familiar with that yet.

That would explain why I've had no issues. My system, data, and cache are 800, 1000, and 500 respectively. For anyone interested in editing these in your own (its very simple and can be done on your phone), I posted instructions a page or two back.
