[Q] F2FS in Note2 Support is needed

Hello All,
I'm not expert in android platform. I found that there are many articles that are talking about F2FS performance in compare to EXT4.
Is there any tool to convert my device t889 to F2FS keeping the same experience? i.e. android 4.3, current ROM DN3 V3.2 LTE, and Kernel AGNI V3.9.4-OC-LTE
Regards

Guys ... Your reply please ... I think this may have significant performance change if it is doable ... Also if there is a way to override all system call to fsync() by fdatasysnc(), it will produce a massive performance change in the whole device

I just did the f2fs and had ROM running OK, did not see any improvement so I flashed CWM recovery and tried to restore a nandroid and it failed on data then phone would boot but gave me an error about having to reset phone. So i'm odining+root66ing my Note2 to get back to stock. I assume Im not f2fs any more.
Question? Once you switch to f2fs, do you have to use devil recovery from that point on to flash new roms?
Can some one explain the options to flashing a new roms once on f2fs, ex: what recovery can be used?
Converting to f2fs was not difficult and will do once again when I understand more.
Cheers, they really need a beer mug icon, but jolly face will do.

Odin will format as ext4. You will need to keep devil recovery in order to keep f2fs as no other recovery can write to f2fs partitions. Ive found though that some zips dont like to install using devil recovery. Once partitions are f2fs, before you can do anything else with another recovery, you need to reformat the partitions back to ext4 ( or go through odin and start all over again lol ).
You will need to use devil and reformat the partitions back as ext4. Then flash cwm / phils touch recovery. Once thats done you can flash a new rom zip. To revert the new rom back to f2fs, Install a compatible kernel (agni and devil so far ), then flash devil f2fs recovery. Reboot to make sure things are working properly. Then reboot into devil recovery to do a nandroid, format f2fs, and restore the new nandroid.
Hope this helps! I just did a write up in the Jedi X2 thread with links.

Yes Saw your post on JediX2 and used you link to get the devil recovery. really not difficult as you explained it. But just posted my question here as f2fs was deviating from rom thread. Thanks again. Cheers.

Read directions in op from thread provided by matt. Performance gains require a little more than converting file system. Added effort is well worth it.

F2fs for the gs3 ??

Yes, I have don't the searches, and tried a ton of stuff including formatting portions. Seems this is working on the international version, and most nexus devices. Is the a thread that might help, or has anyone heard success stories with our device.
I really hate starting new threads, but sgh-i747 seems not to have the information out there for ways to getbf2fs working for data, cache, AND system.

Information on F2FS
There is some information in the Quantum thread starting with http://forum.xda-developers.com/showpost.php?p=53958476&postcount=17136 and several of the posts following it. I tried to get the ROM running but never could get the kernel to boot.

Same question here, I can't even find the option to format data partition in f2fs. I installed latest version of TWRP (2.7.1.0) and I looked in Advanced wipes menu, I selected "Change filesystem" option and it showed me the filesystem choice menu, but I only get the option to use ext2, ext3, ext4 or fat, no f2fs option. I also tried with Philz recovery but I see no option for f2fs in it too.

philz has the option in mount advanced format and you have to toggle ext4-f2fs.
decronic has an successful method for the N5 and has been helpful in supplying tools to convert a rom f2fs and attempting to get me off the ground but the kernel seems to fail on my attempts.
here is a flashable zip to format system, data, and cache for the d2LTE devices. It will completely wipe the internals of the phone so be sure to have an external sd card prepared for your next steps.

Will try when I come back from work. Supposedly CM11 is supported right out of the box, if you use newer than 06/30 version.

I'm attempting to make it work now. I installed Philz Recovery 6.48 instead of 6.26 and I now have the f2fs option. I tried formatting all partitions to f2fs (sytem, data and cache) and I modified the updater script, using the instructions in Quantum Kernel thread, but it failed to boot (won't go past boot splash screen). Now, I'll try to only format /data and /cache partitions.
Edit: using only f2fs on /data and /cache, it won't go past the boot animation. It's a pain in the ass for now, nothing's working.

It successfully booted by using f2fs only on /data but it stopped dead in its track, when it showed a screen telling me that encryption is unsucsessful and that I need to perform a factory reset. Looks like there's really no way at all to make it work. Flashing a different kernel didn't change anything.

Has anybody been able to get F2fs working on their s3? I have been experimenting for hours. So far ive gotten an infinite bootlogo formatting to f2fs and installing quantum 5.2. if i convert quantum 5.2 rom to f2fs and install it gets stuck on gimme pwncakes picture (kernel)

Haven't managed to get it working yet.
I tried flashing a recent CM nightly (with the default kernel) in vanilla CWM, Philz Touch CWM, and TWRP and no luck with any of them. Flashing the Format-All-Partitions zip doesn't seem to work, and if I use the F2FS format options already included in Philz Touch, I am never able to mount /system afterwards. I didn't even have the option to switch to the new file system in TWRP.
So I'm not too sure what's going on. Is it a recovery issue? Or is our device somehow permanently limited to what file systems we can choose from? I'm out of ideas at this point.

f2fs s3
Theres barely any roms or kernels that support f2fs for the d2att s3. I think it has to do something with the compatibility of the rom. Pwncakes has said that his kernel does support f2fs, but im confused whether the rom supports f2fs. Also, most of the tools for f2fs are for the nexus devices, so there might be some error in the compatibility of them. Other devices like the i9300 have kernels that support f2fs as well as dualbooting, but it hasn't picked up for the d2att yet.

I'm not positive, but I think the kernel can be either-or, but the ROM can only be one or the other. So the ROM will have to be made specifically for f2fs.

compatibility
Major kernels such as Kt747, leankernel and QuantumKernel all support f2fs, but theres no compatible rom to go with it. I would love the speed boost of f2fs on my phone if it were possible.

The interesting thing is I tried the F2FS ROM converter tool that was posted in the Quantum thread. The output zip looked like it did in fact have some changes to reflect support for the file system, but I still couldn't get past the kernel image on boot with TWRP. With Philz Touch, I was still unable to mount /system after flashing the ROM.

please post back your progress. Device maintainer said that it has something to do with the Fstab that is preventing it from working for us.
my expirience with Dechronic's rom converter is that it makes use of a modified boot image. I fear the one I have is too old to working with so I am sort of stuck waiting for a further development. its a shame too, I have a spare S3 I can be a little risky with.

F2FS-enabled Kernel and Recovery for JellyBean ROMs

IF you are expert at ROMs and flashing you may find this helpful. I am really happy with the F2FS Filesystem on my OG Note; I've since bought the 2014 version, yet with F2FS the OG Note feels just as fast now. Samsung has put a lot of work into F2FS and reducing flash-based I/O waits is key for eliminating lag on Android.
I did the JB kernel first 'cause that's the source I had lying around. I'm going to build up a proper kernel source tree for KitKat for my 2014 Note in the next few days, then build one for the KitKat OG Note after that. The F2FS is from the tip of Linus' "master" branch, backported to the 3.0 kernel the OG Note uses.
I'm not going to do any newbie handholding- this is for experienced users- but the general way to use this is:
- Backup anything you'll want to save from your INTERNAL /sdcard, as it will be wiped
- Using an EXISTING TWRP (not the one here), make a backup of your /data (onto an external SD-Card)
- flash this recovery, then boot into it
- Wipe the /cache partition- it will reformat it as an F2FS partition
- "Advanced Wipe" the /data partition- use the "scary" wipe that says you'll lose EVERYTHING
- Do a /data (ONLY!) restore from the backup you'd just made from the previous (non-F2FS) recovery
- Wipe Dalvik Cache
- Shut down and go into Download (Odin) mode
- Flash the boot.img provided (it should work on any recent JB Samsung ROM)
- Reboot
- Restore any Internal /sdcard stuff you'd saved
- Enjoy speedy F2FS goodness (give it a minute after first-time booting so it can settle)
The boot.img is here.
The F2FS-enabled TWRP is here.
You know the rules- despite my testing and use, you may lose data, etc. etc. but if anyone uses this, be sure to let me know if it works for you, and especially if you have any issues with it. I'll put out the source to the kernel in time as well.

I've been thinking about going back to Jellybean, this might be the deciding factor.

This is fairly easy to add to any ROM where you've got all the source code (i.e., AOSP and its variants like CM, etc.). I'm pretty sure I won't be making one though, as most non-Samsung ROMs are usually lacking some functionality so I never use one.

Not working on 8013
I followed the instructions, but when I install the recovery, get a boot loop every time. But it was worth a try. Thanks for all your hard work.

It's probably the overclocking. Let me make up a non-OC set soon.

I just got a Notification from the "PM Bot" about this- if anyone's (still interested in?) using this, let me know.

I'd love to use this if we could get F2FS with CM12! By i presume for jellybean only.

This is cool, as just about everyone else said would be great to see KK support for the GT-N8000 KK ROMs ported to GT-N8013. THANK YOU either way AWESOME WORK!

Decrypting Storage

I know on most devices I've owned you needed a non-encrypted kernel and I had to perform a format of data to remove encryption. I have seen a few posts in a couple of other threads but nothing I saw was definitive. Does anyone know if unencrypting the XL is even possible? If so, which kernel are you using?

I also have the same question, I just want descrpt data partition to avoid risk when I turn to TWRP and MultiROM in future,
So anyone try this? I can not understand why I need Magisk here??

" Dees_Troy to allow TWRP to decrypt the data partition involves modifying the same init binary " is NOT what I want according developer's
https://plus.google.com/+DeesTroy Pixel update 4 picture.
What I want is need the full device decryption permanently, on Anroid running time, not only on TWRP.
so, I think that is maybe more than TWRP can do, I guess a special boot.img or a kernel patch zip is need to reach what I need.

Decrypting your pixel is possible. The process isn't much different than any previous Nexus. It differs due to the removal of the recovery partition thus the recovery fstab is now in the kernels ramdisk. So you must edit out forecencryption in both fstabs. (fstab.marlin,fstab.recovery).
Fastboot format userdata, flash a modified kernel, done..
Haven't seen any custom kernels that remove the flag yet so I modified ElementalX.

I did use your modified Elemental kernel that was in the thread about the ability to show that your bootloader is unlocked.
Here is what I did...
Went into TWRP and did a format data from the wipe menu.
Flashed your kernel via USB SD dongle.
Rebooted.
Took about 5-8 minutes to boot but when I went into "Security" it still showed my phone was encrypted. I did this with every Nexus device I've owned but not sure what I'm doing wrong.

How to get F2FS on Nougat Beta - Clean Flashed from FreedomOS - CE 1.11

I clean flashed the Nougat beta 8 on FreedomOS CE 1.11 which is based on OOS beta 7) and I still have ext4 as my filesystem.
The thing works fine except I get serious lags during gaming. I am not sure if this is because of ext4 but I would love to try out F2FS.
Is there any way I can get to F2FS with minimal effort?
Or do I just have to clean flash 3.2.8, factory reset and then flash the beta?
I am basically looking for a better idea than above, if one exists.
Thanks!

i am 100% sure that the lag you are facing is definitely not due to ext4.
If this game lags on ext4 then this game will also lag on f2fs

I will not advise converting partition to f2fs cause there will be no noticeable gain.
and converting partition to f2fs is lot of work. it requires backup of all stuff to pc , formatting whole partition.
And to use f2fs you have to flash custom kernel.
And even after doing this it will give Little to no benefit in real life usage.

in short if you are happy with current setup then keep as it is. but if you want to play with fire then go ahead.

Strange, I understand that a lot of people exaggerate when it comes to their phone's performance and battery, quite a few users reported noticeable difference after switching partitions.
Maybe because of the whole data wiping the phone got snappier and they mistook it for filesystem performance.
Also, I also read a few places that OOS 3.2.8 came with f2fs as default, i.e. if you factory reset, you can get f2fs with the stock kernel.

I already have TWRP .28 so that can be marked done.
I was reluctant on converting the partition using TWRP in the anticipation that it might give me a bootloop or something since I am on the Nougat beta which may not be too happy with TWRP filesystem conversion.
Can you tell if this should work on Nougat beta or you want me to try myself :silly:

No.
Stock kernel on oos 328 doesn't support f2fs. for f2fs you have to flash custom kernel like elementalx, blu_spark, etc.

community builds are different from stock oos.

Also, don't forget that stock OB8 only has support for F2FS on the /data partition, not the other partitions.

yes it should work N Beta , but as mentioned above in another comment the N beta supports f2fs only on data so only convert the data partition...
you wont get bootloop as long as you stay on TWRP .28, i did get a bootloop when i flashed the official TWRP, actually i got a black screen then bootloop (was a bad situation)...so stay at ..28 as long as you're on Nougat and/or with the N beta firmware( because some CM roms require you to have the N beta firmware) other versions of TWRP are not compatible with N beta firmware
you'll get an extra messege about dm-verity ilike the one about the unlocked bootloader but that's normal.
if you want to go back you need to 1st convert the data back to ext4 , then flash the oos 3.2.6 (or above 3.2.7 or 3.2.8) firmware and modem (firmware only available on the forums) and then wipe everything then flash official TWRP then reboot back to recovery (official twrp) then follow the regular flashing procedures.(i prefer doing 1 more wipe on official TWRP), also after a full wipe that includes internal storage you need to reboot back to recovery (not system) then copy the required files back to internal storage and flash

I clean flashed the Nougat beta 8 on FreedomOS CE 1.11 which is based on OOS beta 7) and I still have ext4 as my filesystem.
The thing works fine except I get serious lags during gaming. I am not sure if this is because of ext4 but I would love to try out F2FS.
Is there any way I can get to F2FS with minimal effort?
Or do I just have to clean flash 3.2.8, factory reset and then flash the beta?
I am basically looking for a better idea than above, if one exists.
Thanks!

you should wait for the official 7.0 from oneplus. like I am. if you gain f2fs system, there won't be any performance improvement or whatsoever.

Backup your data and do factory reset you'll get f2fs. In my experience my OP3 feels snappier. Cold start of apps are improved.

Wiped the /data partition using TWRP (28) without selecting System or internal storage.
Now /data partition is f2fs - which is the intended partition as per OnePlus.
