Kexec support is already included.
This method is not yet supported. The current dualboot setup zip and Fakecwm is not equipped to handle CM10 yet, but for the brave, here are some directions to make it work. It works for me, but as usual, use at your own risk.
If you try this, I would recommend deleting any previous CM9 *.img files from your multiboot/CM9 directory and rerunning the dualboot setup zip. Alternatively, you could move/rename the data img file if you'd like to restore your CM9 data to a future CM9 boot. It may work, but I would not recommend booting CM10 with CM9 data or vice versa.
NOTE: a slight modification to the cm10 update zip needs to be made until the fakecwm can be updated. This modification should not be done if you are not using the dual boot utility. The updater-script needs to be edited:
Replace the line:
format("ext4", "EMMC", "/dev/block/mmcblk0p14", "0", "/system");
with:
format("ext4", "EMMC", "/dev/block/mmcblk0p14", "0");
1. Delete previous CM9 *.img files from multiboot/CM9.
2. Reflash TeamEpic-SGS3LTE-multiboot-cm9-setup-v1.zip to create fresh disk images.
3. Copy
boot_CM10.zip to your phone.
4. Flash boot_Fakecwm.zip.
5. From within the Red colored Fakecwm, flash your modified cm10 update zip.
6. Optionally flash the jb gapps.
7. Flash boot_CM10.zip.
