[Galaxy S II General] marjune23:
DUALBOOTING 2 NeatRom (Stock NeatRom and NeatRom AOSP)...

revisions in blue color...

I decided to create this thread for all NeatRomers who likes to experience both the NeatRoms on your phone...

With this, you will avoid flashing from one NeatRom to another NeatRom...

I got no problems using both NeatRom (the only problem is, I can't decide which one to use)...

So I keep on booting from one NeatRom to another...hahaha...:laugh::laugh::laugh:

So for those who want to try dualbooting but afraid or lazy like me to read all necessary thread...

This step is for you guys...Good luck...:D:D:D

Requirements..

1. AOSP NeatRom...

2. Modified Stock NeatRom...

3. Dorimanx Kernel (I stongly suggest to download branch 8.43v76, only known stable release so far)...

4. Minimum of 3gb space on your internal storage...

Setting up 1st Rom (AOSP NeatRom)...

1. Back up back up back up...(I suggest Obackup for backing up and Nandroid Manager for Restoring or Titanium)...or Nandroid will do...Make sure to have a minimum of 3gb on your internal storage...

2. Download and flash compatible CWM for Kitkat...

3. Reboot to Recovery (not boot)...

4. Wipe everything (data, cache, dalvik) and format (system, cache, data, preload) >>>need to do this to avoid any fc's again and complain blah blah blah...

5. Flash our dear latest NeatRom AOSP and Gapps...

6. Reboot to Recovery again (not boot)...(this recovery will be TWRP, for those who hate TWRP don't panic, just tap on Install button)

7. Flash Kernel_Dorimanx-V8.43v76-Comp-[00-21]-[17-02]-JB-SGII-PWR-CORE.zip....

8. Reboot to Recovery again (not boot)...(now your back on CWM recovery)

9. Flash this to downgrade into MaliV2 (necessary for KK dualbooting with JellyBean)...

10. Reboot and enjoy the 1st Rom...(in here you've successfully installed NeatRom AOSP on 1st Rom)...

You may omit or skip step 10 and proceed to step 11 if you want to continuously install the 2nd Rom (I prefer this one to avoid booting the 1st Rom immediately)...

Setting up 2nd Rom (Stockbase NeatRom)...

11. Reboot to Recovery again (not boot)...

12. Go to mount and storage then format /cache, /system and /data for secondary rom...(do this only if you face black screen or bootloop after first try dualboot installation)

13. Go to dual-boot option...

14. Wipe data/cache and dalvik-cache for 2nd Rom (this will take long as it prepare the images needed for the 2nd rom)...

15. Still under dual-boot option, select flash zip from external/internal storage to flash modified Stock NeatRom (look for modified NeatRom and download from thread ROM KITKAT & SAMMY BASED MODIFIED FOR DUALBOOT...

16. Reboot...(not reboot on recovery anymore)...

17. Dori bootanimation it will ask you which Rom you want to boot...(press any key to boot 2ndRom or none for 1stRom)...

18. You may now restore your data using Nandroid Manager or other apps for restoring. (Optional)

19. Enjoy...
