Recovery and Rom for All-F2FS

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.

What is All-F2FS?

We used F2FS only for /data. It was simply because we have only to flash a compatible Kernel and Format /data partition. With All-F2FS we use F2FS for all partitions and we need a compatible ROM


Instructions:

Compatible ROM:

• Slim-mako-4.4.2.build.4.8-WEEKLY-3891-F2FS.zip
• Slim-mako-4.4.2.build.4-F2FS-2.zip
• Make your ROM with Convert To F2FS

(All credits to authors. I have only made them compatible with F2FS)

• Download compatible ROM
• Download FormatPartitions.zip
• Download "special" TWRP for All-F2FS: openrecovery-twrp-2.7.1.0-mako-All-F2FS.img
  (This is different for that of simply F2FS)
• Copy FormatPartitions.zip and ROM on Phone
• Flash "special" TWRP with Fastboot
• Flash FormatPartitions.zip with new Recovery
• Reboot Recovery
• Flash ROM with new Recovery
• (Flash GApps with new Recovery)
• Go to Wipe Menu and press Format Data (The Big BUTTON!) (You will LOSE all your Data! Music, Movies etc!!)
• Reboot

(Recovery has a RED back button to remember you that you are using the F2FS recovery!)

If you get something like "Unable to mount '/cache'", Flash FormatPartitions.zip and reboot recovery.

Enjoy

Phone is snappy and smooth with All-F2FS.

To go back:
- Flash a "normal" recovery
- Format Data
- Reboot Recovery
- Flash RestorePartitions.zip (Untested)
- Reboot Recovery
- Flash your previous ROM

(Required commit)

@legolas93 I didn't test it yet, but I took a look in your updater-script of the ROM. There is something like this: "dev/block/platform/sdhci-tegra.3/by-name/APP". Isn't that the nexus 7 partition name?

Thank you! You are right! It was not a big problem but it's better to correct it Done!

Just to be sure I have to ask this. The current F2FS kernels provided in your other F2FS thread won't work with this, right?

Why you say Download "special" TWRP for All-F2FS if this is the same recovery you post in only data F2FS?

 

[jmtjr278]

Nope. It is different. Says so right under the DL link.

Why you don´t look at the download from the 2 posts before talk!?

Open both and you will see the same link = The same recovery

RestorePartitions.zip
does not work

Open both and you will see the same link = The same recovery

the important part is the formatpartitions.zip, as this formats the /cache and /system partition to f2fs. the recovery formats the /data partition to f2fs as far as I know

Sorry. Wrong link! Fixed now :silly: Thank you.

@legolas93 The required commit is kernel stuff from bricked nexus 5 kernel, if I understand correctly.

Any particular commits for adding F2FS support to a ROM?

What's the difference between this thread and the other F2FS one? The same partion zip is posted in that one as well.

In other F2FS version only data and cache partition change to F2FS but this mode also formate system partition to f2fs(in addition to data and cache)

@legolas93 what ils needed to change tout make a ROM working on all F2FS ?

 

[jolinnard]

Thank you @legolas93. Slimkat works sweet. Definitely something in my kernel mods or Rastakat aren't well configured for f2fs. I will stay in your build for a while.

RestorePartitions.zip
not work, "normal" recovery can't mount sdcard

 

[ph37rd]

No Root

If I do not have root access, is it just a matter of reflashing the ROM?
EDIT:
have to enable it in developer options.

How long should first boot take?

 

[jolinnard]

How long should first boot take?

A minute or a little more.

I uploaded a modified Hellsgod kernel for people who have all partitions with f2fs. Enjoy.
Also a HellsDoctor, too.

The only change is in fstab.

 

[slickw]
