DUALBOOTING 2 NeatRom (Stock NeatRom and NeatRom AOSP)...

As I suggested before, try dualbooting to feel both superb NeatRom by our master on your S2 phone...

For 1week, 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 NR to another...hahaha...:laugh::laugh::laugh:

For almost 1month, 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 NR 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...:D:D:D...

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)...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 ASOP 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 latest DORIMANX KERNEL 8.43vXX from dorimanx test site...

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

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

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

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

You may omit 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)...

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

11.1. 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)

12. Go to dual-boot option...

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

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

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

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

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

18. Enjoy...

Big thanks to...

Maybe you will find few items that will not work, like the ff...

1. Flashing of Mods that requires preload or system folder (only this modified mod will work)...

2. Video player on v5.6 Fc's, but will be able to play if you open the video file itself (known issue in Dori AFAIK)...

3. BBS apps dont work on AOSP (but you can use Gsam Battery Monitor)...

4. Light keys control on settings doesn't have effect (but you can use BLN to control it from Stweaks)

5. Ram will reduce by 50mb (will be use for video driver of Dori I think, please correct me if am wrong guys)...

That's all I think

FAQ (by me hahaha)...

1. Where is the preload folder of AOSP NR?...

- there is no preload folder for Kitkat...

2. How about the preload folder of NR v5.6 (2nd Rom)?

- it is located at /data/data_sec...

3. Can I swap both Rom?

- yes, you may do it in dual-boot option under recovery mode..

4. Why 2GB+ was taken from my internal storage?...

- see /sdcard0/.secondrom (there is an image file used for dualboot).

5. Can I flash other MOD?

- AFAIK if the mods has nothing to do with preload and system folder you may proceed. (I hope somebody can give us a help to modify those MOD to be able to flash specially those MOD for NR v5.6)

6. How's the battery life?

- So far so good. Again, battery drain / consumption will still depend on the phone user and apps that was installed.

7. I forgot the other question...:D:D:D:rolleyes::rolleyes::rolleyes:
