/* Switch to f2fs */

As mentioned above, this kernel fully supports f2fs.
However, you are completely free to choose not to use f2fs.
You can selectively convert partitions to f2fs using PhilZ Touch recovery provided in the downloads.
Don't expect TWRP to work with f2fs because its maintainer kindly ignored my requests to provide sources for TWRP.
You should use the provided PhilZ Touch recovery at all times after you switched to f2fs.

This step includes a full factory reset!
Backup your data prior to switch!

You may use the provided recovery to back-up previous ext4 data to an external storage
and restore it to newly formatted f2fs storage.

1. Install normal ClockworkMod(or PhilZ) recovery
2. Put arter97 recovery on you SD card
3. Enter recovery
4. Flash recovery
5. Reboot recovery
6.1 Select "Mounts and Storage"
6.2. Select "toggle f2fs ext4 migration"
6.3. Select "format /cache"
6.4. Select "f2fs"
6.5. Select "Yes - Format device"
7.1. Select "format /data and /data/media (/sdcard)"
7.2. Select "Yes - Format"
7.3. Select "f2fs"
7.4. Select "Yes - Format device"
8. Reboot

You can repeat the steps for /system. It's your choice.

Initial release

FONTE : XDA

 

PREREQUISITI :

Custom Recovery (TWRP , CWM , PhilZ Touch Recovery)


MODALITA' D'INSTALLAZIONE :

- Scaricate il Kernel per il proprio dispositivo dal seguente sito : arter97

- Copiare il file all'interno della memoria del telefono

- Flashate il kernel da recovery -> FINE .

ATTENZIONE :​

Se volete passare dall' arter97 kernel ad un altro kernel dopo aver installato il nuovo e riavviato il dispositivo potreste andare in bootloop poichè l'arter97 kernel va a modificare alcune librerie del vostro dispositivo . Per risolvere basta ripristinare le librerie originali manualmente , oppure riflashare prima la ROM e successivamente il nuovo kernel (Tranquilli! Cosi facendo non perderete nessun dato all'interno del telefono) .

 

Disponibile v10 beta 2

Inviato da Mountain View tramite Samsung Galaxy S6

 

Disponibile v11
