Same here, lost root on rasbean, and on cleanrom. Then it is no easy way to get root back, switch kernel doesnt help for me at least. I need to have root where I live, so only quick test, but kernel makes the system very fast and responsive.

[Nexus 7 Original Development] tanoxxx:
:good:

Thanks, i will try it and report you :good:

only a question before try it, i dont need F2FS, what happens if i use this kernel without change data partition to F2FS? it will work good and without any problem?

there is a risk i lost my data on sd or system?

what about backups and others features by recovery? like i say i dont need and use F2FS, my normal TWRP will fully work with this kernel?

what is the difference between by F2FS and EXT4?

if i use this kernel with F2FS without change the data partition which will be my data partition?

Sorry for this many question, i need to know this, after that i will try your kernel :good:

thanks
[Nexus 7 Original Development] TeamMex:
I made the kernel for 2 versions one for Ext 4 and other for F2FS

this work but you need EXT 4 ramdisk

If you dont make a format data not problem you not loose nothing

YES YOU CAN USE NORMAL TWRP but YOU NEED KERNEL VERSION EXT 4 (need fstab with support to EXT 4)

if use this not problem, only problem is if use F2FS kernel, system can't mount Ext 4 data

so you need Ext 4 ramdisk :)

cheers.
[Nexus 7 Original Development] tanoxxx:
Really thanks :)

but sorry, there is something that escapes me :confused:

i dont need F2FS and F2FS kernel, I'd like to try your normal kernel, but you say me i must use the F2FS kernel, because you update only that.

now, can i use this F2FS kernel without change my data partition, all will work good? I mean performance and all features in TWRP recovery?

Sorry again for the question

Thanks.

Sorry if i not thanks with the button, I would like to, but i finish my daily thanks :(
[Nexus 7 Original Development] TeamMex:
Bro the V17 kernel have 2 versions

if you don't need F2FS use this version 3.2.5-XPerience17.zip - 5.17 MB <--EXT4

NOT NEEDED CUSTOM TWRP and NOT NEED FORMAT ANYTHING.

Cheers.
[Nexus 7 Original Development] tanoxxx:
:good: but sorry, you say me here

do you have update the ramdisk to CM only in this version or also in 3.2.5-XPerience17.zip - 5.17 MB <--EXT4 ?

I would like to try 3.2.5-XPerience17.zip - 5.17 MB <--EXT4, but in OP there is write

3.2.5-XPerience17F2FS.zip <-- F2FS CM based rom

only F2FS version work on CM based rom or the -EXT4 will work too on CM base rom?

Thanks, and really thanks for your patience

:confused::confused::confused::confused:
[Nexus 7 Original Development] Fransis88:
Hello, I had a small problem difficult to explain and not continue.

I already had my omnirom with legokernel and f2fs correctly with the modified TWRP who posted there. then install your kernel with support and was still running f2fs everything perfectly. then change your TWRP for your TWRP appear and I returned the encryption of data, as if I had reverted file format. I return to reformat data, correctly note that says "format data using f2fs", meaning that all ok. I will install a rom from a USB flash drive or from internal memory, and gives me error "update script" or something and I do not install it.

I'm back to put the TWRP legokernel the page, and I have the same problem.

I imagine that the return to an original TWRP it would solve, but I was very happy with omnirom and f2fs and your kernel and do not want to EXT4, plus I like to know what the hell is going on my tablet?

thanks

-----------------------------------------------------------------------------

I have something more advanced. TWRP normal the problem is solved again using TWRP and Ext4. when I install modified TWRP gives me error when installing the zip, and the error says "Error executing updater binary in zip" This was a mistake that gave TWRP to top out kit kat, I think it is problem of version of TWRP that ye used , 2.6.3. because in future versions and stay solved that problem.

you can use the latest TWRP and modify it to be compatible with f2fs, I'm so sure that my problem would be solved.

thanks

-------------------------------------------------------------

part 3-----

problem is not the version of TWRP.

anything, that has not happened to my tablet.ni your recovery from legokernel nor install anything with it. The partition is formatted in f2fs, reboot, try to install something and nothing ...

Original install TWRP, formatting data ext4fs and I can install the rom and other things without problems.

makes me angry, because if it worked before and now I do not work neither yours nor the layman. FULLY tablet is formatted and now I will install TWRP usual, and had omnirom as your regular kernel, and I'll stick with that combination ever since the tablet I need to work daily. a shame. I record it but if someone else happens and I can shed more light on this matter.
[Nexus 7 Original Development] frantisek.nesveda:
The problem seems to be on CM's side, something must have changed in latest nightlies. On 20140306 I had the com.android.phone problem on both this kernel and on LegoKernel, but on 20140301 they both work fine. So my advice is to use the older 20140301 nightly with this kernel until this gets resolved.

If you want to revert to the older nightly, you have to do a full wipe, dirty-flashing won't work, as you will have problems with com.android.acore etc. And you better download it quick, I don't know for how long they keep old nightlies available for download.

[Nexus 7 Original Development] qu3becker:
I'm not 100% sure but Data-F2FS kernels(like this one) doesnt work on All-F2FS. The system partition just won't load so it doesn't go past the Google logo. What I'm sure if that every kernel that used to work on F2FS formatted data partition cannot work on All-F2FS roms.

[Nexus 7 Original Development] TeamMex:
what AOSP or CM?

maybe wrong upload so Tell me please.

changed links for f2fs to use F2Fs kernel's you need

partitions on F2FS

System, data and cache.
[Nexus 7 Original Development] graphdarnell:
You mean even the system is on F2FS format? I used Slimkat 4.4.2 nF2FS. Have no idea if system is F2FS there. But I guess system can be rewritten in that format. What if I want to keep just data in F2 format? What do you advise?
[Nexus 7 Original Development] TeamMex:
You need format system,data and cache with moded TWRP from legolas

Maybe you use EXT4 system and only F2FS data.
[Nexus 7 Original Development] graphdarnell:
Lego's TWRP sets up system in EXT4 and DATA in f2fs alright. Your kernel still don't work with it. Hangs on flashing Slimkat logo. I would have loved to test it. Thanks for your info and work anyway.
[Nexus 7 Original Development] TeamMex:
bad you need ALL F2FS recovery

System F2FS needed , Data F2FS needed , CACHE F2FS needed

My KERNEL F2FS is for all partitions if YOU DON'T HAVE ALL Partitions ON F2FS not work -_-

IF YOU USE EXT 4 systen and DATA f2FS tou need older version of my kernel not the new.

Cheers.
[Nexus 7 Original Development] graphdarnell:
My bad. Lego's FormatPartitions changes everything (system,cache,data) to f2fs. I just checked mine with disk info from googleplay. It still doesn't rhyme with your kernel. Wonder why?

I have not gotten me any of your kernels boot, neither version of CM or AOSP version. I tested with pac and C-Rom. and does not start. in my case, not even pass the screen of google.

greetings and thanks

hola amigo, gracias por el trabajo como siempre!

no he conseguido que me arranque ninguno de tus kernels, ni la version de CM ni la version AOSP. he probado con pac y con C-Rom. y no arranca. en mi caso, ni siquiera pasa de la pantalla de google.

If anyone wants to try their luck, here is the F2FS-on-data version that is working for me well. I took the All-F2FS CM version and just modified the fstab for my partition layout. All credits to [MENTION=4403780]TeamMex[/MENTION], I just changed one file.

Just to be clear, this is NOT All-F2FS, you have to have /system and /cache on EXT4 for this to work.

do we need flash lego kernel before flash Xperience ? or lego kernel's ramdisk is already included ?

and another thing : with every kernel i used with F2FS ( faux123, Xperience, LegoKernel...) i got the same bug : Sometimes i need press 3-4 times the power button to Wake-up the device .

Thank for your hard work.
[Nexus 7 Original Development] TeamMex:
Sorry? Legoramdisk? no this my own ramdisk

Maybe is a deepsleep of the rom i don't have this issue.

Similar experience here.

Running All-F2FS with CarbonRom. It was working just fine before flashing this. Yes, I have All-F2FS recovery. Yes it was working with All-F2FS just fine. I know what I'm doing. It just hangs on the bootscreen.
[Nexus 7 Original Development] chaostrodamis:
Same here
[Nexus 7 Original Development] frantisek.nesveda:
Hi, would you mind testing the attached zip? I don't have All-F2FS and do not want to reformat my tablet right now, so I can't test myself.

I thought it was strange that this kernel is not working on All-F2FS, but when I changed the fstab to Data-F2FS, it works just fine, so I tried to modify the fstab for All-F2FS somehow so it would work. Basically I just copied the fstab from All-F2FS Slimkat, which is working for some people, and repacked the boot.img, no big changes. So all credits to TeamMex, he made the kernel.

Be warned, it may not work anyway, so make a backup or be prepared to roll back somehow.
[Nexus 7 Original Development] heymoe:
Booted up fine on my grouper + Slimkat. Everything mounted F2FS.
[Nexus 7 Original Development] frantisek.nesveda:
Thanks!

So, the problem appears to be with TeamMex's fstab for All-F2FS, because that's the only file I changed. I don't know which mount flags are the problematic ones, though. That would need further investigation.
[Nexus 7 Original Development] Mr_JMM:
Mahdi Rom

Has anyone got this to work with Mahdi ROM?

I tried with the 3.2.5-XPerience-18AOSP-F2FS.zip version (please let me know if this was the wrong one) and I'm using All-F2FS (system, cache and data) but it gets stuck at the boot animation.

I was hoping this would work so that I could take advantage of the kexec patch and use MultiROM.

Thanks for any help.

[UPDATE]

That (3.2.5-XPerience18CM-ALL-F2FS-test-mod.zip) worked. I was surprised as it's a CM kernel. I now have MultiROM working on SlimKat and Paranoid with All-F2FS. Thanks.
[Nexus 7 Original Development] lotherius:
Took me forever even though I asked about it, and others already proved it before me.... but... it works ;)... CarbonRom with All-F2FS using your kernel. Next step of course is a universal kernel, but this is good :)
[Nexus 7 Original Development] frantisek.nesveda:
I'm glad that it works for you :)

If you by universal kernel mean a single kernel which can be installed on any partition layout, try this (warning: blatant self-promotion). But that is just a tool which modifies the kernel on install and patches it for the right partition layout. I also tried some ugly hacks which would allow us to boot a single boot.img on any partition layout, but I got into some problems and I need to investigate why those happened, but I don't have that much time now because of school.

I see this was designed for some specific roms, but not specifically PA roms.

I decided to try it on the new PA 3.98. It is running flawlessly. And even though i know many people don't put a lot of stock in benchmark scores (antutu) I can tell you that at least on my nexus 7 this kernel scored 20% higher than Franco, Faux, and M kernel. Absolutely no slight to the other kernels. This one for me just runs better.
