[Q] Dual boot EXT4 and F2F2 - LG Optimus 2x

I am using DualBoot and currently have 2 ROMs both with EXT4 system.
I would like to flash latest DJNoXDs Slim ROM 4.4.4. with F2FS and to keep CM ROM with EXT4 system.
Does anybody know is it possible to flash 2 ROMS, one with EXT4 and other with F2FS, on one O2X device by using DualBoot?
Tnx.

[Q] Need help with ext3 and ext4.

Hi i'm new here and i have some question need you guys help.
1)I'm now on stock rom and kernel with ext3 file.Do i need to do anything if i want to load new rom or kernel with ext4 from cwm 5.0.2.0?
2)If my current rom or kernel is ext4 and i want to load back to ext3,what should i do?
Sorry for my bad english.
You don't need to do anything to switch to EXT4, ROMs convert on install. Take a backup of your stock setup, you can restore that to get back to EXT3 as you're using CWM v5.
Thanks you Rusty!
So the newest cwm will automatically convert it to ext4 right?!Except for ext3,i need to convert it using backtoext3 from Paul or restore back to stock.
No.
A ROMs updater-script will convert to EXT4 if it needs it. CWM v5 will convert back to EXT3 when restoring a backup of an EXT3 ROM.
Thanks again Rusty!
I get the picture now!

[Q] Does ACE support ext2?

Hello,
I want to know whether the original ROM for ACE support ext2, ext3, and ext4 filesystems. I have partitioned my sdcard in 3 partitions one is FAT32 and the others two are ext.
Thanks.
ext2, yes. its supported even on stock samsung rom with stock kernel.
ext3 and ext4 no, need custom kernel.

Thanks I will check it.
Just installed EXT2 for Link2SD on a Samsung Ace stockrom 2.3.5. This works.:good: First tried EXT3, didn't seem to work.
Stock rom plus stock kernel supports ext2 but stock rom with stock kernl doesnt support ext4 or 3
I would recommend you to flash nims kernel and use ext4 type and use ext4 tweak by mr slaid to improve performance
Give it a shot

The kernel needs to support ext4. The stock kernel does not, so if you want to use ext4 you also need to flash a custom kernel.

[Q] Which CWM version for ext4 fomat, for Cooper?

I am currently using CWM 5.0.2.6 as it is universally suggested the appropriate for Galaxy Cooper.
The problem is that this version can only format the sd card up to ext3, and not ext4.
I want to try the Ulimatum rom with all its goodies and I need ext4 format in partition for Swapall. My sd card is super fast class 10 u3.
I have read that in many cases 6.x.x.x versions end up in blue screens or fail to reboot.
Although I use minitool for partions, when installing a new rom at some point devs ask to format memory before installation, so even if it was originally in ext4 it reverts back to ext3 after the CWM format with the 5.0.2.6 version.
Which version I can safely use for ext4?

You can use the ext4 format with CWM without problems, CWM's version is NOT important, but it can't create this typ of partitions, so you need ypur PC to create an ext4 partition (Gparted, Minitool partiton magic...)
If you want to flash The Ultimatum Rom or another CM7 based ROM you must use a CWM 5.x based recovery.
Use CWM 6.x just for CM11
To use ext4 format >>> all versions are safe
To flash the Ultimatum ROM >>> CWM 5.x

How can I flash roms with f2fs?

Guys I'm new here and I do not know much about roms or recovery modes and it's functions. I have a question for you. Some of the roms support f2fs filesystem but whenever I try to install them on my device, it flash roms by using ext4 function. I have never be able to flash them by using f2fs. For example Los 13, Los 14.1, RR roms have f2fs filesystem support. I convert my system and cache to f2fs from ext4 but it doesnt work at all. It installs the roms by using ext4 always. How can I flash them with f2fs filesystem. I have heard that f2fs is faster than ext4 therefore I want try it

I have tried that but whenever I try to install a rom with a filesystem formatted as f2fs, it converts it to ext4 at the beginning of the installation. Can I convert my filesystem after installing a rom? For example after the installation of LineageOs 14, can I convert my filesystem as f2fs? Does it harm my phone?
