[ROM][All-F2FS] OmniROM with All-F2FS support [30/03/14] - Nexus 7 Original Development

OmniROM with "All-F2FS" support​
I have modified OmniROM to work with F2FS partitions. All credits for the ROM to OmniROM guys.
This is for "All-F2FS" that mean that /system, /cache and /data are formatted with F2FS.
This is needed to switch to "All-F2FS".
ROM contains my Kernel with "All-F2FS" support and other goodies.
Ported sl[aou]b from Linux 3.4
Ported timer and workqueue from Linux 3.4
Ported random from Linux 3.13-rc4
Ported rwsem from Linux 3.11
Kernel NEON Mode
Etc..Etc..
Added GPU OC (Franco way..)
Added Toggle for FSYNC
Revert CPU OC things (We don't need it and it was a bit dirty..)
One of the goodies of my kernel is that i was able to reclaim more 18MB of RAM for Android. As you can see in Settings we are now at 993MB.
MultiROM isn't supported as now because i need to patch it to work with "new" ram.
What is F2FS?
F2FS (Flash-Friendly File System) is a flash file system created by Kim Jaegeuk at Samsung for the Linux operating system kernel. The motive for F2FS was to build a file system that from the start takes into account the characteristics of NAND flash memory-based storage devices (such as solid-state disks, eMMC, and SD cards), which are widely used in computer systems ranging from mobile devices to servers.

Wow.
Held off installing on my Sprint S4 but this looks like the perfect thing to try on my tablet. TYVM.

Can u pls upload somewhere? Media fire is so slow and that is when the download actually starts which it rarely does. Can u upload on g drive or anywhere better like zippyshare.

Hi, I have installed this rom and seems to work very fine. But I have only one problem. When i try to install Xposed Framework this message appears. This is related to Rom or SU problem? Thanks

---

Hey, just flashed the ROM. Followed the procedure point to point except I also flashed ur legokernel and superuser zip cause omni ROM isn't rooted from default and then I formatted everything. Now I rebooted and its stuck on Google logo.

Any chance we can get a AOSPAL all-f2fs build? It is the #1 smoothest fastest trouble free ROM I have ever tried on my N7. Please?

Ya I'm hoping for a AOSPAL ALL-F2FS support as well. This is my current daily driver and might be the one I stick with. Its vary smooth, stable and fast. Also nicely customizable as well.

this was an issue for me as well. i restored the stock nexus 7 software and tried starting from pretty much complete scratch. i'm afraid to reboot because of that, but will give it a shot.
on a related note, i've gotten a system message saying that there's an update for omni-4.4.2-20140313-grouper-NIGHTLY.zip
are updates to be turned off until there's an F2FS update available?
edit: just rebooted, everything rebooted nicely.

Yes turn them off for now.

I discovered the problem with my procedure. I was using the gapps recommended by omni team that I use with the regular omni ROM, the ones from the PA gapps thread. Those were the problem. Also, Lego kernel isn't working with this ROM, N7 gets stuck on Google logo.
Edit: after a second series of flashes I have came to realise that actually the gapps were also the fine. Its the Lego Kernel that was messing things up. Tried the M-kernel f2fs and that also isn't working and is resulting in a freeze at Google logo. Now I am just gonna give up on kernels and just flash omni ROM, gapps and superusers.

As has been said before legokernel and m-kernel and all the other kernels as far as I know are NOT ALL-F2FS supported yet. They are only F2FS on the data partition. This OmniROM will not work with those kernels until someone can modify them to work with ALL the partitions formatted to F2FS file system a.k.a ALL-F2FS. No one has done that yet...

Thanks for the rom. Overall the n7 has become much snappier than it used to be. Is there anyway to revert the theme of the playstore back to the stock theme? I don't like it. Some texts are not readable

I've never had experience with this filesystem but have had similar messages when using inbuilt superuser on their ROMs.
I would suggest using the latest SuperSu as it's complaining it can't use the mount and copy commands which do need root.
