Clean wipe is recommended!!

Installation

Make a backup!

If you were on CM 10.1 or a stock ROM prior to 4.2, upgrade to 4.2.

Install ClockworkMod recovery with SELinux support. Older CWM will result in a "status 7" error.

Install the ROM using ClockworkMod Recovery

Optionally install the Google Apps Addon

Wipe data if coming from stock

Optionally enable dual SIM support.

Dual sim works---

How do I enable Dual SIM?

To enable or disable, run the following command from adb or terminal emulator and then reboot. SIM Settings can then be found in Settings -> Multi Sim Settings.

Enable:

su
setprop persist.radio.multisim.config dsds

Disable:

su

setprop persist.radio.multisim.config none

Note that Dual SIM mode currently has the following limitations:

Both SIMs are always enabled (no way to disable one SIM)

"Receive incoming call while data is enabled" is always enabled

The QuickSettings tile will display the status for the currently selected SIM for data

There is no arrow activity indicator in the status bar.

Changing 2G/3G network mode using the QuickSettings toggle is not supported, only do it from Settings.

Changing 2G/3G mode in Settings may show too many options if the language used is not English. If more than 3 options is shown, only use the 3 top options (which will be WCDMA only/GSM only/WCDMA preferred regardless of the actual label shown).

3G may not work properly if Dual SIM mode is enabled with only 1 SIM inserted

Cannot set different ringtone for each SIM

Baseband version not displayed in Settings

F2FS INSTALLATION

I have modified CosmicCM to work with F2FS partitions.

This is for "F2FS" that mean that /system, /cache and /data are formatted with F2FS.

This is needed to switch to "F2FS".

ROM contains my Kernel with "F2FS" support and other goodies.

What is F2FS?

F2FS (Flash-Friendly File System) is a flash file system created by Kim Jaegeuk at Samsung for the Linux operating system kernel. The motive for F2FS was to build a file system that from the start takes into account the characteristics of NAND flash memory-based storage devices (such as solid-state disks, eMMC, and SD cards), which are widely used in computer systems ranging from mobile devices to servers.

A must read..

You need a recovery with "F2FS" support. So..

Downlaod This modified latest philz recovery

http://www.androidfilehost.com/?fid=23329332407585722 (6.26 version)

https://www.mediafire.com/?ylurtlmf0lnoj99 (6.40.4 version)

To format partitons /system and /cache

http://www.androidfilehost.com/?fid=23329332407585694

To switch your /system, /cache and /data partitions to F2FS follow instructions:

Keep in mind that you will lose all the files on the memory of your grand i9082.

You need:

- Two files you can download above (philz 6.26.1/ 6.40.4 recovery and FormatPartitions-f2fs-system-cache.zip)

- A ROM with "F2FS" support (Like my CosmicCM-version 3.0 / 4.0/4.1/4.2/4.3/4.4...and above)

- GApps (i think you want PlayStore.) Usual GApps.

Copy a ROM with "F2FS" support to your externalSD card.

My latest evolution kernel v1.7.6. http://www.androidfilehost.com/?fid=23329332407585881

Copy GApps to your ExternalSD

Copy FormatPartitions-f2fs-system-cache.zip to your externalSD

Reboot in recovery

Flash new philz recovery by me

Reboot in new recovery

Flash FormatPartitions-f2fs-system-cache.zip

Reboot recovery (It's needed for some reasons..)

Flash ROM

Flash Evolutionkernel v1.7.6 ( not needed from 4.5/4.5.1/4.6.0/4.6.1/4.7/4.7.1/4.8 version and above ...)

Flash GApps ( not needed in CosmicCM 4.0/4.1/4.2/4.3)

while in recovery mode connect mobile to PC and start Terminal and type-

adb shell

type

mkfs.f2fs -l data /dev/block/mmcblk0p21

Reboot

Done.

It's easier than it seems :)

Now you have f2fs file system on your mobile with latest CosmicCM...enjoy...

Disclaimer : - Above formating and installing f2fs rom procedure is dangerous and can brick your mobile....

Do it on your own risk. I will not be responsible for your phone or any other data loss...
