Does converting data from f2fs to ext4 takes a long time? Seen somewhere that I may take up to 90min. So if anyone has done it can you please tell me? When I converted from ext4 to f2fs it was very fast. Thank you.

Anyone tried this, and any reason it wouldn't give a speed boost?

Just to inform you guys, swap doesn't support yaffs2 ;-)
Ah yes, I see. I wonder if you could create a ext3 img on /data and mount that, then create a swap file on there. Wonder if it'd be worth it...

Hey guys
Recently I've got a ZTE V970M (MT6577) phone and so far it's awesome. However, some people have been asking for a way to extend the /data partition because some games are heavy 'n stuff. That's alright.
There is a method which resizes the partitions by altering the MBR on the EMMC and that way the /data partition ends up with 2GB (from [email protected]) + 512MB (the assigned for /data), but I want to do something different, without having to edit the MBR that way. Dunno, it's fishy imo.
My idea was to format [email protected] (which comes in vfat) as ext4 and then editing init.rc and change the partition mount points from [email protected] to [email protected]
If I do that without formatting, the phone boots but it asks for an encryption key. Reading on the net, it's not asking for an encryption key, it's the fallback mode for when it can't mount the /data partition and then it believes it's encrypted, but it isn't.
If I format the [email protected] to ext4 (mke2fs -T ext4 /dev/block/mmcblk0p6), parted shows it's on ext4 and all that shiz, but the phone seems to disconnect itself from ADB once it finishes booting, and hangs in bootloop. Since I can't ADB it, I don't know wtf is going on with the phone. Something tells me I'm close to reaching the goal though.
Looking on the net I found this useful link -> http://blog.kangkang.org/index.php/archives/242 which talks about extending /data the way I want to do (for the Tegra2 one, but it shouldn't matter). However, Chinese isn't my main or secondary language (lol) and google translate does an horrible job at translating it.
So, anyone got ideas on how to extend such partition? I just want to swap the normal /data partition with the internal SDcard partition, so in theory if I format it to ext4 and swap the mount points it should work, it's just a swap, but why it isn't?
Any ideas are greatly appreciated!
Thanks in advance!

I hate bumping but, nobody yet? I've seen this being done in other phones... any ideas?
I can't believe no one has an idea yet... come on, this is XDA... wtf is up?
Yeah, I wanna know this too. If formatting the EMMC on my Note1 to anything other that the FAT32 will help?
When i wipe my phone and format data with f2fs there is around 520mb of space already taken but when i use ext4 there is only around 120mb taken.
Can anyone explain this? Thanks.
This is normal. F2FS simply has higher overhead than EXT4.
Hey
Can someone tell me how do I modify update script to get f2fs on system partition? Thanks
any one?? I know there is line in script that formats /system/ to ext4 but I don't know how to delete it properly
I got it, if someone is interested here it is http://forum.xda-developers.com/showthread.php?t=2776430
I wanted to start customizing a ROM for our s22 and I was wondering how can I make system and vendor partitions read-write
to edit the files inside
for ext4 it was possible to unshare_blocks. not sure it's possible for f2fs. but you could convert into ext4 still..
