but when i formatted whole internal memory in f2fs and later formatted whole internal sd by menu advanced wipe it formatted again in ext4...

so when we want to flash new rom we need format whole internal sd again?

BTW seems new unofficial zip is online

edit: [IMG="niiice"]http://www.reactiongifs.us/wp-content/uploads/2013/07/its_working_star_wars.gif[/IMG]

edit damn i got it working once but play store crashed so i flashed second time and i cant boot it XD WTF only problemsXDXD

ok [MENTION=4719724]Adam77Root[/MENTION] i now know what u mean and seems we dont need to format whole sd everytime when flashing.
[LG Optimus 4X HD] EB20XY:
yeah!

It worked to install unofficial cm11 with twrp and f2fs!

great !

used this instruction to do it: http://xdaforums.com/showpost.php?p=53766591&postcount=1200

hope it helps other too.
[LG Optimus 4X HD] gerciolisz:
i have it working too now... seems not everytime twrp mounting sdcard properly for me...
[LG Optimus 4X HD] Demetris:
hmm i might know how to fix that :)

Done
[LG Optimus 4X HD] tool_king:
Can you tell us some first impressions about the performance compared to ext4?

And is there a possibilty to restore data after formatting to f2fs?
[LG Optimus 4X HD] EB20XY:
performance is not worse than before.

Our P880 stays quick. :laugh:

So, no disadvantages sofar.

restore data:

Well I have just installed my apps new and before starting I backuped up the system and all important things to the external sd.

That mean also the new CM11 ROM, cause you will loose it on internal for the time of installation ;)
[LG Optimus 4X HD] tool_king:
But no advantages as well, right? ;)

So, it's not possible to restore the app data by restoring an ext4 TWRP backup or with Titanium?
[LG Optimus 4X HD] EB20XY:
advantages: sofar perhaps sometimes bit faster load of some apps.

restore with twrp is only possible if the former format in the partitions is the same (that can be switched and formated with twrp via versa like you want any time). but you have to do that to come back.

also if the devs decide to exclude system from f2fs, we have to reformat system later again. but that is perhaps not a tragedy, cause the data is still on f2fs then.
[LG Optimus 4X HD] laufersteppenwolf:
Alright guys, sorry for the late reply, but I was on my uncle's birthday ;)

Now, yes, I uploaded a new, fixed ROM including a fixed updater script.

About the instructions, as already mentioned:

0) make backups (including titanium backup)

1) flash the F2FS TWRP recovery image

2) manually format /system /data and /cache to F2FS (WARNING: internal sdcard will be wiped as well)

3) flash the F2FS ROM

4) flash GAPPS

5) boot

Regarding custom kernels, if you don't use the default kernel, please don't make bug reports. If we know that the ROM and kernel are working properly, then we can go on. But for now, if you run into problems using a custom kernel, please keep it to yourself.

About restoring data, if you restore your /data partition via recovery, the old filesystem will be restored as well (ext4). This means, you cannot restore your old backup via recovery. However, if you have a Titanium Backup backup, you sure can restore this.

If you have further questions regarding F2FS, feel free to ask here or hit me (us) up on IRC ;)

I will later also make a thread in the AD section, regarding various F2FS tools/info/... including the F2FS recoveries, the patch to make a proper updater script while compiling a ROM,...
[LG Optimus 4X HD] gerciolisz:
Biggest advantage is when u enter apps in settings. List of apps loading very fast XD

Overall a bit smoother and faster but only a bit.

But paid apps issue is really annoying with this kernel
[LG Optimus 4X HD] Optimissimus99:
Can we also let /system ext4? Or is there need for formatting all partitions with f2fs
[LG Optimus 4X HD] laufersteppenwolf:
No, /system has to be f2fs as specified in the fstab. Also the updater script requires a F2FS filesystem ;)
[LG Optimus 4X HD] nasosgr:
please uplaod v24-6-2014 version

For us that we do not want to erase the whole partition of our phone, is it possible to upload again the 24-6-2014 version ? My 22-6-2014 has the problem with the dialer that i wrote some posts above and is quite annoying..

Thank you
[LG Optimus 4X HD] heliflieger9:
The S3 Mini people does backup there /data partition.

A tutorial is located at http://novafusion.pl/tutorials/how-to-use-f2fs-s3-mini/backup-ext4-f2fs/

I think this should also works with the P880, but I have not tested it at the moment.

Boot problem.

I have now tested the version with f2fs.

It does not work.

I have installed the recovery and formated the system, data and cache partition. All looks fine, but If I reboot and open the recover again, the f2fs partiton fata and cache are changed to ext4 again.

The same problem is during boot the CM ROM.

It looks like, that the data partition will changed to ext4 every boot:

I/installd( 6431): installd firing up

E/cutils ( 6431): Failed to read /data/.layout_version: No such file or directory

E/installd( 6431): Could not create directories; exiting.

E/keystore( 6432): chdir: /data/misc/keystore: No such file or directory

I/Netd ( 6436): Netd 1.0 starting
[LG Optimus 4X HD] EB20XY:
for me it works fine.

But in twrp I was first also confused, cause after switching the partitions to f2fs later again it showed still ext4.

But then I just tried to switch them and gone to format-data-menu-point and done it.

Installed directly ROM and gapps.

Can you please try exact this instruction:

http://xdaforums.com/showpost.php?p=53766591&postcount=1200

btw:

Only issue I have sofar with latest unoffical CM11 is nothing with f2fs (that works fine sofar), but very slow GPS fix. Whyever ..

[MENTION=5741501]heliflieger9[/MENTION], Thats what I did, You need to format the Partitions '' Manually'' in TWRP Recovery. Flash F2FS recovery Zip in recovery reboot into recovery and do Following steps.

0. Backup your data on External SD via Titanium Backup.

1. Boot into Recover.

2. Backup your working ROM.

3. Go to Wipe->Advanced Wipe->Check the Partition System->Tap Repair or Change File System->Change File System-> Select F2FS->Format->Finished Go Back to AdvancedWipe Screen

4. Select Cache-> Follow the same process from Step 3.->Finished Go Back to AdvancedWipe Screen

5. Select Partition Data-> Follow the same process from Step 3.->Finished Go Back to AdvancedWipe Screen

6. Select Partion Internal Storage-> -> Follow the same process from Step 3.->Finished Go Back to AdvancedWipe Screen

7. Format Data in Wipe.

Now you have a F2FS Format Internal SD Card and Partitions.

Flash Rom, Wipe Cache, Install Gaaps, Wipe Cache and Devlik.

Reboot and Enjoy.

If you get some andorid.com Force Close or something like that Flash Gaaps again, and Wipe Cache& Devlik again.
[LG Optimus 4X HD] heliflieger9:
OK, now the phone comes up.

But every time I booted into Recovery it says that /data and /cache is an ext4 partition. :confused:

Update: Now its right in recovery, very confused....
[LG Optimus 4X HD] EB20XY:
Yes, it is confusing,but works. :laugh:

You can use the app "diskinfo" to check if all is okay.
[LG Optimus 4X HD] gerciolisz:
I was facing same problem but it seems foxed only in sources by [MENTION=1149134]Demetris[/MENTION].. My theory is recovery wasn't mounting data partition properly sometimes. Just reboot recovery few times and when your partitions looks OK in f2fs flash rom.

Or wait till someone compile recovery w with fixed sources
[LG Optimus 4X HD] laufersteppenwolf:
About recovery, I have a new CWM build which seems to work, but isn't completely tested (only flashing and formatting), so stay tuned ;)

[MENTION=4065751]gingerboy92[/MENTION], I didn't look into your logs properly yet, but I highly doubt wpa_supplicant crashes are F2FS related ;)
[LG Optimus 4X HD] LGaljo:
I think that if somebody has problems with ROM not booting after wiping partitions and flashing f2fs build, problems might have been caused by not mounting /system, /data or /cache partition in TWRP. I resolved my problem with mounting them. Can somebody confirm?

EDIT: Germany won against Algeria 2:1
[LG Optimus 4X HD] gingerboy92:

Super. Installed already. Seems to work fine. Will continue to use it. :)

But it would be perhaps very helpful to get some parts of the 1st post refreshed.

(Requirements: correct f2fs-recovery etc.; Download-Links and never devDB ?; Status working/not working and of course Installation incl. switch fo f2fs)

Then everyone who comes new to unofficial CM11 know what to do for usage and perhaps differences to official CM11, ;)

ext4 vs f2fs

Hi. Does anybody notice big different between ext4 and f2fs. What are the first impressions? Benefits and disadvantages in daily usage.
[LG Optimus 4X HD] EB20XY:
I used now both for some days and my impression is, that f2fs was no improvement in speed etc.

In contrast when I switched now to official CM11 I must say it is even faster and more reactive.

Perhaps just integration of new grouper blobs to official CM11 as only change would be interesting.
[LG Optimus 4X HD] Jack_capvil:
The last build of Unofficial CM11 does not boot properly on my device. I wanted to test this version of CM11 (I use Offical version normally) and after booting the ROM stops just after showing LG logo wich stays always on screen.

[LG Optimus 4X HD] giga111:
Hey guys,

I'm experiencing two problems with the latest build:

1st: Unlocking the screen is slightly delayed.

I haven't had this with the official CM10 and stock. It somehow has improved until now, however. The unlock-time was longer. In the beginning after flashing it was extremely laggy at times, also at the unlocking process (I know, you should let the phone rest/restart in the beginning, but i did that several times which didnt help)

2nd: I always need to mark SMS as read to remove the notification from the top bar (only with SMS, not with any instant messenger). Clicking the message won't remove the notification, i have to click it twice. Is there a way to resolve that?

Thank you! :D

How 2 use the F2FS CWM? I have tried to use it but it Fails at Installation. And i cant compile TWRP. I have really treid but at the Moment it costs me too much time to find the Errors in my build virtual machine. Where is the Option to Change file System in CWM? ( At the Moment im on STOCK because old recovery messed up my whole /data Partition (i think it tried to wipe the Cache in ext4 but it was f2fs and it didnt detected it right))
[LG Optimus 4X HD] thegrim11:
Use the All in one toolkit to flash the basic TWRP recovery, then go get the F2FS TWRP .zip and it on your SD card and flash it within TWRP, Doing so will update twrp to the F2FS recovery and from there you can use these instructions to install a F2FS ROM:

http://animus7-development.tk/device/p880/CarbonROM/README-VERY_IMPORTANT.txt
[LG Optimus 4X HD] Optimissimus99:
Yes, but with the f2fs recovery the Mounts doenst seem to be OK. And CM (Latest Version, w/ checked md5!!) Gives an error while installing (error executing updatrer binary) :( if i Change file System, after A reboot /data and /Cache are often showed and handled as ext4 (dont know if if just detets the file System not right, or if there were Errors while formating). ANd if it Shows the file Systems correct, the cm Installation even Fails :( (with updater binary error)
[LG Optimus 4X HD] sprite048:
Although wrong topic, but I have this same issue on twrp by wolf and on official cm. I have to format /cache a hundred times, then it cahnges to f2fs. But after a reboot it's shown as ext4.
[LG Optimus 4X HD] LGaljo:
Before formatting you must mount partition
[LG Optimus 4X HD] IcanhasLG:
It'll be unmouted before formatting occurs anyway since you can't format a mounted partition (in Linux, a mounted partitions filetable is read at mount time and since a format inevitably changes the filetable it has to be unmounted to perform the operation).

You shouldn't have to format it more than once either, obviously something is wrong here.
[LG Optimus 4X HD] LGaljo:
This is a big problem, but I don't know how to solve it. So I usually spend twenty minutes to make ROM properly boot and mount internal storage. I'm also experiencing issues with camera and music playback on unofficial CM, but this is different story...
[LG Optimus 4X HD] IcanhasLG:
I don't really get the point of f2fs at this point in time. At best you'll notice half a seconds improvement during database operations but sequential reads which is what is absolutely mostly used is slower on f2fs than it is on ext4.

Just because something is newer and updated doesn't mean that it's better.

I don't really want to drag testers away from this ROM becasue laufenstepperwolf has done a great job with it but if you're having problems that cannot be easily resolved i suggest you move to another ROM.
