[Samsung Galaxy W I8150] Paul_Kolanjian:
Hello everyone! Thanks to @educk and @h0rn3t for their awesome dualboot project for ancora, and @theloneseeker for his amazing tutorials, I've managed to make ION kernels compatible for dualboot in secondary ROMs, in other words, you're primary ROM can be ION or non-ION, but the secondary ROM had to be non-ION build to work, but now, I've managed to make ION builds dualboot compatible. Therefore, CyanogenMod 10.1 beta 3, CyanogenMod 10.2 alpha 5, CyanogenMod 11 20140323 build (the final 20140413 seems to be unstable for some) and Dark CyanogenMod beta 3 can be installed as secondary ROMs. The procedure on how to dualboot is mentioned in this thread http://xdaforums.com/showthread.php?t=2469803, but I will still provide you with a similar guide in order to avoid errors.

**Installation Guide**:

1- Download the Dualboot1.8.apk from the mentioned thread above in the downloads section.

2- Install busybox and the Dualboot1.8.apk and grant the app root access.

3- Tap on Partitions and set the partition table according to your preference (I have a 4Gb external SD card so there are no exact values for everyone). This step takes most time so be patient.

4- Once done, tap on Tools and then Prepare flashable zip, and direct it to the ROM.zip you want to have as your secondary ROM (ION builds are now working)

5- Choose to wipe data and cache, then choose to Flash now. In recovery, tap on flash untrusted zip and after flashing is done, reboot.

6- Using a file explorer, you will see on your internal SD card that a Dualboot folder exists, and according to your secondary ROM, create a 4.2.2 (for CM 10.1) or 4.4.2 (for CM 11) and place the corresponding boot2.img that I provided. So, you should have something like Dualboot/4.4.2/boot2.img for example.

7- Go back to the Dualboot app and tap on Switch

Viola! Now, you will have ION build secondary ROM! You can have two 4.4.2 ROMs as well, or any other combination

NOTE: The kernels I made are 100% tested by me and are working with no issues whatsoever.

-Mr. Radu (arsradu) for his kernel collection and bringing CM 10.2 for our device. :)

-Osama (Madridii) for his kernels and all his wonderful work and D CM 11 :highfive:

-Daniel (theloneseeker) for his amazing tutorials :)

-educk and h0rn3t for bringing dualboot feature to the i8150! :victory:

-Roderick (Tazerick) for motivating me ;)

-lafactorial for his powerful Khan Kernel!!

-hurtsky for the rock solid HurtSky kernel!

-sir mordred for bringing TRIM to the ol' i8150 :) (perfectly working with dualboot)

P.S. If any user wants to have his custom kernel work with dualboot, please give the name of the kernel, the kernel version, the linux version and a link to download the kernel, and post what ROM the kernel works with (e.g. xxx kernel version x.xx.xx working with CyanogenMod X.X) and I will do my best in making the kernel work with dualboot.

I AM responsible for any damage that may happen to your device. I do not own any of the kernels or ROMs or apps that have been used to make this project possible. If any user encounters an issue, kindly report the issue and post exactly what your steps are. The guide posted here is the same as educk mentioned but maybe more simplified. I do not deserve any credit, I only made the kernels dualboot compatible but I didn't build these kernels. The kernels posted are the default kernels of the ROMs (simply extracted the boot.img only). Good luck to everyone :)
