[GUIDE] Convert /data to f2fs with TWRP 2.8.+ [TF700T]

rattboi · Feb 4, 2012 7 7 0

Hi,

I'm in the process of getting my TF700t going as well as it can, and in that process I've installed TWRP KANG 2.8.7.4. I'm not interested in backing anything up. I'm totally fine starting from scratch on everything.

Following your guide, it says that when I format /data, it may take up to 60 minutes. I did follow this correctly, I think. "Format data" -> "type yes". It formatted it, but it took about 30 seconds at the most. Did I do something wrong? Everything is currently very snappy in Zombi POP, but I'm concerned that it will slow down over the next few weeks (as I've experienced in the past with the TF700 and other roms).

Any thoughts on why my case is different from your guide?

I wouldn't worry about it. Maybe they dropped the secure erase in the last version? IDK, have not run the formatting yet. Would be a question for @lj50036

I have had a few reports of this over the years.....

This has something to do with the tablet itself....

I still included secure erase for sure......

Maybe if @rattboi is willing to pull some info off the tab, I could know more...

But either way if you are doing.... wipe / format data / type yes... It is doing a secure erase....

Thx Josh

I just did this on my TF700 and the format /data took at least 30 minutes and possibly 45. I wasn't timing it, and walked away for a while so I don't know for sure...

This will involve formatting /data .....

So let me know when and if you are going to do such things...

We can do this then....

Thx Josh

I'm down for the pursuit of knowledge. I've barely got anything installed on it at this point anyways. Would be easy to get back to where I am. Next steps?

boot into twrp
format data
reboot back into twrp

Code:

adb shell hexdump -C -n 104857600 /dev/block/mmcblk0p8 > hexdump.txt

this will output the hexdump.txt file to your PC in the currect dir
upload the file

Thx Josh

It's the same thing, but truncated, right?

Correct....

But it redirects the output to your PC rather then the tablet....

So no need to adb pull it off......

I am still learning myself.. :good:

You need anything else? Inconclusive results?

Nope, sorry

Looks like to me that it is doing a 'secure erase' which is good

I cannot tell you why it happens so quickly, but that is part of the game....

Thx Josh

Using F2FS modified TWRP; no option for F2FS?

I downloaded the TWRP specified at the very beginning of this thread (2.7.0.0 / red go-back arrows) and when I select 'Wipe' then "Advanced Wipe" there is no option to change file system type, even after I've selected a folder.
Any suggestions? Just run the format.zip file?
Thanks!

berndblb · Feb 8, 2016 at 10:04 PM

You did not download the recovery specified in the OP.
2.7.x is way too old and does not do file system conversion

Enter TWRP, choose Wipe > Advanced Wipe

To Convert INTERNAL /data to f2fs
Check the box for "data"
Tap "change or repair file system"
Tap "Change file system"
Tap "F2FS"
Swipe the button

I did this, and got a message saying encryption can't complete and the tablet needs to reset.
When I try to do so, it boots back into the twrp, tries to complete again, fails, and repeats.
I have a nandroid from before this happened but can't break out of the loop now.
Any suggestions?

berndblb · Aug 13, 2016 at 12:51 AM

Have you tried a full format of data? This takes an hour or more. Let it finish.
Then convert to f2fs.

That sounds like to me, that the ROM you installed does not support f2fs...

If android cannot mount /data it assumes its encrypted..
