The steps i followed were ::
- Select Tools section. Then select the rom slot you want. If this is the first time you use that rom slot you need to setup system, data, and cache images for the rom. In page 1 of the tool, check "Setup System" and "Setup data & cache" to setup the images. You need to do this only one time
- In page 2, select "Wipe system", "Wipe data", and "Wipe cache"
-And the most important one, select "Mount Partitions". Don't forget to select "Mount Partitions" otherwise it will overwrite the data and mess up your phone rom.
-Press Next until complete, and don't reboot the phone. (If you see any error, reboot in to recovery and try again)
3. Make sure you don't see any error in the step 2. then you can now flash any rom you like as normal. It will be flashed to the rom slot you just select in the step 2. Don't reboot after complete because you need to flash a dualboot kernel after.
4. Flash Chuan_Dualboot_Aroma_v1.8.zip again, then select "Set Default Booting Rom", then select the same rom slot in step 2.
- Then select "SDCard" as default, and select "Don't Share"
As i was planning to use ultimate xxlsc and jelly bam i decided to use phillz 3.99 dual-boot as the kernel after choosing no for the kernel install
and then i setup the second rom Jelly Bam 5.1 as sdcard 2 but leaving "default booting rom" as sd card 1
but the problem is i can only access the rom installed on sdcard 1 and even after pressing home button on and off i cant access the second rom ..
