I made a F2FS conversion to Data Partition.When I made a restore the Data Partition cannot be Mount or do a Format.With any recovery(CWM,TWRP,Philz) the Data partition Cannot be mounted or formated.What Can I do?I read threads on the Transformer Forum but nothing of these working for me :crying:

Only one that can mount it will be twrp 2.7.1.1 (or the f2fs twrp released in dev)
If it has corrupted just format it back to ext4 and start again.
This is the log when I press wipe or repair partition.in the mount menu i cant select any partition

That's not a log, it's a screenshot. The log is in /tmp/recovery.log, so you can use adb pull to get it and post it. Or you can probably use the "copy log to SD card" option in the advanced menu.
Here is the log.I compressed the file because the log format is not supported to attachments.

According to the log, your recovery can't access any partitions on your eMMC. To find out more, reboot to your recovery again and run on the connected PC:
Code:
adb shell dmesg > dmesg.txt
adb shell cat /proc/partitions > partitions.txt
and read/post the resulting files.
Here is the two files your commands gave me

Your tablet's eMMC seems to have no partitions at all:
Code:
<6>[ 4.770320] mmcblk0: unknown partition table
What exactly did you do for "a F2FS conversion to Data Partition"? Did you format mmcblk0 instead of mmcblk0p8?
The only thing I did after f2fs conjversion is in Philz recovery I select wipe to install a new ROM.And the problem began.

If you expect help, you need to answer my question. I did not ask what you did *after* the f2fs conversion - what exactly did you do to convert /data to f2fs?

Friend! You got the attention of one of the few people who may be able to help you get your tab back! Use it!
Post DETAILED steps of what you did or _that is going to ignore you!
Which recovery and version thereof did you use?
What did you do afterwards? You mention 3 recoveries. Did you flash all of them?
What did you do in which order in each of them?
Provide as many details as you can!
First I used the modded twrp recovery from the f2fs thread.I did the f2fs and the chromi-kk work successfull.But because battery drain I wanted to install the last chromi-x version based to stock firmware.Next,I didn't convert f2fs back to ext4,but I made a full wipe with twrp 2.7.1.1.And my problems began.
Also I tried full wipe from the latest CWM and Philz recovery with the same results

Define "full wipe".
Which CROMi-X version did you try to flash?
Details, details....

OK So your issue is that you have left your data partition as f2fs and installed a kernel/rom that does not understand f2fs.....
So as I see it - install a recovery that will reformat as EXT4 - format data and start again?

How would you format data without a data partition?

I tried that but the TWRP gave me a ERROR message(cannot mount Data).Tomorrow i will upload screenshots and full logs for that,because my transformer has empty battery because of the attempts

So try formatting from adb?
Code:
adb shell
killall -19 recovery
make_ext4fs /dev/block/mmcblk0p8
reboot

When I doing the command (make_ext4fs /dev/block/mmcblk0p8) I receive the message : Need size of file system.
Something seems to be wrong with your GPT. Unfortunately the busybox tools don't support big offsets to read it, so let's first see if the Tegra-specific partition table (which is not used by the kernel) is still there - that won't help you immediately but will show if the eMMC can be read at all and where the partitions are supposed to be. Post the output file of this command:
adb shell hexdump -s 0x300000 -n 2048 -C /dev/block/mmcblk0boot0 > pt.txt
i wanted to know if it is possible to format our system partition as f2fs and have it work our data partition on kitkat is already f2fs so are we able to do it to system? in twrp i attempted this by fro matting to f2fs but when restoring system it reformats system as ext 4 is there away around this? on twrps website there is a command to keep a the file system it is "tw_rm_rf – uses rm –rf instead of formatting system and data partitions, this option is used to prevent changes to the file system settings such as file system type, " i found it here http://www.teamw.in/twrp2-reference-guide would this help to do this? i don't know where to put this command in though
Edit: on a sidenote i formatted cache as f2fs and it booted
Edit 2: i looked at it again and cache was reformatted back to ext4

Did you ever succeed in getting stock "DATA" partition to F2FS? I couldn't restore my backup and phone wouldn't boot anymore.. so went back to EXT4..
Maybe @djvita knows something, I think he has been experimenting a bit with F2FS..

yes i was able to get only the data partition to f2fs no other partition will stay another format once it boots it reformats or when restoring system in twrp it will restore the system partition as ext 4

interesting.. how did you do it? I did it in TWRP 2.8.1.0 via advanced wipe and after that got stuck on the motorola bootlogo..
That is the same thing I did but after whipeing I restored my data partition. I think the reason you got stuck in a bootloop is because you did not clear dalvic and cache or you do not have the kit Kat boot loader

I tried it again.. this time it worked.. I rebooted after format directly back into recovery and was then able to restore my data from ext4 to f2fs.. not sure, why it didn't work the first time around, but thanks for checking back!

Go to
TWRP >WIPE >ADVANCE WIPE >SLECECT partation u want to change (data and cache) >click on repair / change file system > select repair file system >click f2fs
Maybe the rom couldn't install because i've changed 'system' partition to f2fs ?
thanks guys
Hi, I'm new to flashing custom rom. I've accidentally change the file system of my Dalvik Cache to FAT, (the default is ext4). I want to revert it back to ext4 but when I select it, it says invalid partition selection. I haven't flashed a custom rom yet. What should I do next?

AFAIK, dalvik-cache is just a directory present inside /data partition, which is EXT4 formatted (or even F2FS)..
How did you even do that??
There's no separate partition for dalvik-cache.
Maybe you would have changed the file system of /cache partition..
And, to make it clear, /cache partition doesn't hold dalvik-cache.

In TWRP, there's a Wipe option and then I selected Dalvik-cache and mistakenly change the File System to FAT. Now I can't mount it.
Is there any guide on how to convert my s7 to f2fs ?

Go to recovery and simply format your partitions to F2FS. Don't forget about backup. Anyway, I really don't recommend using F2FS on other partitions than system and cache.

Hi. DON'T EVER NEVER TOUCH TO SYSTEM !!
Only Data and cache.
Use compatible TWRP and Kernel.
