I never changed to F2FS before I installed the ROM.

If I change the partition to F2FS, will my apps & settings not get deleted?

If yes - If I do a TWRP backup (saving it to my computer), change the partitions to F2FS, am I able to restore everything from the backup or will it not work?

My other question is do I have to reinstall the ROM after changing to F2FS or does that not get affected?
[Nexus 7 Android Development] St3ve32:
Hi :) I believe, that it is not possible to restore ext4 nandroid backups onto a f2fs system. But for sure it is possible using titanium backup. So if you backup everything you want using titanium and then put all the titanium backup files to your computer along with the personal data from internal storage (as the device gets wiped all together), than flash the rom and than you should be good to go and restore again :)

Welp in the middle of installing something from the play store it rebooted and won't load. I can get to the bootloader but even recovery doesn't load. I had just installed the Rom the day before without issue. Suggestions?
[Nexus 7 Android Development] SkOrPn:
Reflash the recovery? Then see if the recovery can help you with the roms problem. If not, maybe you have to start fresh from a stock setup.
[Nexus 7 Android Development] unconfuse:
Thanks for the reply. TWRP flashed fine and I kept a copy of last_kmsg. I don't think I've ever had a reboot kill my recovery partition and corrupt the os too. Very odd. I was previously on a ext4 kitkat rom so maybe it just couldnt handle all the excitement. :p
[Nexus 7 Android Development] SkOrPn:
LOL, yeah maybe. Id see if the recovery can delete the apk that the google play store tried to install. But it could just be a simple sun flare or a gremlin or something, lol. Ive had weird stuff like that before and no explanation. It sucks....

Thanks for the build, running well so far except for the camera. I see from your OP that you removed the camera but any camera app that I've downloaded from PS force closes.

I'm not sure but I think there may be some dependencies missing from the rom that will allow the camera to work. I browsed the lib folder and added some files from another 5.0 rom but to no avail. I'm sure I missed something. :p

Anyway, nice job and thanks again. Also, Happy Thanksgiving to all that celebrate it!

Whooops, I just requested a dedicated Freak-SlimLP thread BEFORE realizing you had already changed the title of this one. Please forgive my PM.

Yes, this ROM is running great so far. Its a little bit of work and more basic then I expected. Does not have ROOT, or at least it didn't for me but you guys should be using the new SuperSU 2.35 in the play store anyway, it is now out of BETA status for LP. REALLY fast after it settles down, and I mean FAST. Also, I noticed something odd, for being called SLIM it is using more system space then any rom I have tried all year. So, this must be the SlimFAT-LP version, haha... After removing 10 system apps I am still at 12% free, when I am normally around 25% free. Not sure what else I can remove, as I have already seen Android complain about TTS being gone and a few others. Got rid of calc, browser, google now launcher, launcher 3, and half a dozen more.

Anyway, all I really care about is speed and stability, and it has both for me. Thanks Freak :good:

Which gapps are you guys using?
[Nexus 7 Android Development] puttytatko:
Are the justarchi optimizations applied to lollipop as well? I mean the entire rom and not just the kernel

At the moment not because it´s not compatible with L yet

F2FS Version is uploading

Hi, Did the advanced reboot menu enable / disable option get moved somewhere when upgrading from slim to newest optipop ROM 5.1.1? I enabled reboot menu but its not the advanced one with recovery option. In slimlp, it used to be in security menu. I've checked numerous menus. BTW, I did a data wipe clean install.
[Nexus 7 Android Development] adomol:
Yes, if you save the backups somewhere off your device and then change every instance of ext4 in the file names for the data/cache backups to f2fs so twrp knows to format them accordingly. If you are also using f2fs on system, remember to edit those nandroid flie names as well. Basically, edit the file names for any partition backups that are going from ext4 to f2fs.
[Nexus 7 Android Development] SkOrPn:
It should be in the "Optipop Tweaks" > "Power Menu" tab. It is the advanced reboot menu by default now, no way to turn it off. Just enable reboot menu (which it should have been already), hold the power button, you will see the word "Reboot" click on that and it will give you the advanced reboot options.
[Nexus 7 Android Development] keepasa:
That's the reboot option I selected on the power menu of the optipop. I then hold power for 2-3 sec and get menu and click on reboot, warns that it will reboot and it does. Strange no option for recovery.
[Nexus 7 Android Development] Lar5:
Thank You for sharing this ROM :good:

I've tries a lot of different Lollipos ROMs and most of them feels snappy at start but then they start to lag.

This build [29/05] with the TK Gapps micro is perfect. No lag or strange slow downs. It's a keeper for my Grouper ;)
[Nexus 7 Android Development] Reiven89:
I tried again to flash this rom and i got stuck on google logo, also twrp got on infinite bootloop so i had to unbrick from Nexus toolkit.....this is the last time i flash this rom for sure
[Nexus 7 Android Development] hokiealumnus:
Did you try a different Gapps, like Slim gapps? Some have had problems with the gapps linked in the OP (including myself). However, I doubt the ROM or gapps caused the TWRP bootloop.

Don't be so quick to blame the ROM for problems that aren't the ROM's fault. Many people have flashed this without issue, so the chances of it being at fault for your problems are extremely low. But hey, if your post to take a jab at the ROM makes you feel better, by all means, knock yourself out.
[Nexus 7 Android Development] secret.animal:
Also just to state as I have read by many people and if you research it enough. F2fs is really best for data and cache. As system is read only which ext4 is better as it reads faster then f2fs. Though f2fs is faster writing, which the cache and data does a lot of.

You may find better performance changes with just those two changed.

Do know this, data format to f2fs will wipe internal memory storage. So what you have on the tablet you may want to back up and put somewhere else.

Yeah, well I don't know then. When I click on Reboot, it then gives me four options, Reboot, Soft Reboot, Recovery and Bootloader. I do not remember enabling it though, it was just like that by default I think. I am on 5-22 with MKernel a77.

[Nexus 7 Android Development] wrkerr:
I have the advanced reboot menu, and am using the default kernel in the latest build, so I don't think it has anything to do with the kernel.
[Nexus 7 Android Development] SkOrPn:
It doesn't have anything to do with the kernel. What launcher you using? If stock, try using nova launcher and see if you get the advanced reboot. I never use anything but Nova.

[Nexus 7 Android Development] oswald-p:
Hi there,

I would like to try this rom which looks very promising to me (slimrom on my old nexus S is running like a charm).

I tried several times to install it and I always had the same issue after the installation: the tablet boots ok but is very, very, very slow at a point that it is not usable. It takes several seconds between touching the screen and having a result, moreover the tablet becomes very hot.

I tried several minimal GAPS packages (the link in the first post, the one from slimrom.net, the one from PA) and also no GAPP at all, with the same result.

I also tried to re-format /system, /cache and /data (using TWRP 2.8.6) with no luck (using F2FS for /cache and /data)

At the moment, I am running Cyanogenmod with no issue, but I would prefer a lighter rom.

Does any one has a clue of what is happening?

Thanks.

O-p

edit: problem probably solved
[Nexus 7 Android Development] noldar:
Do you have the last firmware ?

I'm on f2fs, no issues, no lag, best n7 rom !
[Nexus 7 Android Development] oswald-p:
Yes I tried optipop build from 29th of may.

I am trying again, re-formatting everything... flashing the last slim zeo gapps to see if it is better.

O-p

EDIT: this time it seems to work :) the only change for me is the latest slim zeo gapps.

Thanks for your help.

Does anyone know how to get xposed to work with this ROM?

I tried flashing the latest zip (xposed-sdk22-arm-20150514.zip) for 5.1, but the rom won't boot afterwards.

Or perhaps I have the wrong xposed?
[Nexus 7 Android Development] noldar:
No issues for me with this release (last alpha arm not arm64). Maybe you restored xposed installer and some incompatible modules with titaniumbackup ?
[Nexus 7 Android Development] nereis:
Interesting, mine appears to be stuck on boot screen as soon as I flash the xposed zip, let me see if fix permission / redownload and such would fix the problem.

Thought it was potentially a selinux issue, but after set permissive still no go on stock lean kernel, will try m-kernel next.

Why are 3 listed? Difference? I am currently running F2FS on data and cache on CM.

I having the same Problem with stuck @ google sign, with all opti roms.

old slimlp working fine.

I tried several different gapps, no change.

Than i changed system from f2fs back to ext4, now its working.

Is this suposed like this system needs to be ext4?

MFG Alex
[Nexus 7 Android Development] canodroid15:
Yes, Only format data & cache as f2fs system ext4

---------- Post added at 12:05 PM ---------- Previous post was at 12:02 PM ----------

The slimroms are older 5.0.x & probably unsupported. Opti-Pop is currently supported & under development? & fast as hell, I run it as ext4 all the way & its fast as hell & buttery smooth
[Nexus 7 Android Development] SkOrPn:
Yes that is how it is supposed to be since ext4 is faster at reading the system partition. It tells you in the OP to keep system as ext4.
[Nexus 7 Android Development] jasch:
Ok, i was coming from 5.02 slimlp and there f2fs was working as System, so i didint really read carefully.

Just started having this issue today, when I use an app like mxplayer and use sw decoder for audio to boost the audio it would begin to crackle on the speakers and the headphones aswell. Any ideas? Thought it may be due to the speaker but would that cause the headphones to crackle aswell? If I were to have it full blast on normal it would be ok but when I enable the sw decoder and raise the volume it begins to crackle. Going back one release to see if it still does it or no.

For system, it's ext4 (as it's much faster anyways because it's readonly) and don't try f2fs and it will NOT boot. For data and cache, definitely f2fs!

Hey Guys,

Running latest ROM (5 June) and I'm having problems watching video with BBC iPlayer (https://play.google.com/store/apps/details?id=bbc.iplayer.android), specifically the media player companion app that iPlayer launches, BBC Media Player (https://play.google.com/store/apps/details?id=air.uk.co.bbc.android.mediaplayer). Upon launching a show to watch with IPlayer, I just get a blank (black) screen. Quick look through logcat and I've found the following each time I've tried to watch a show through iPlayer:

E/ActivityManager( 486): ANR in air.uk.co.bbc.android.mediaplayer
E/ActivityManager( 486): PID: 21760
E/ActivityManager( 486): Reason: Broadcast of Intent { act=android.intent.action.SCREEN_OFF flg=0x50000010 }

iPlayer used to work fine on previous builds, works fine on my Maguro and the kid's Grouper's running 5.1.1 stock... Any ideas anyone?

OK I managed to update to TWRP 2.8.6.0.. Thanks all. So I am about to flash this ROM. I would like to flash the best possible LP so I have noticed that there is an f2fs version. Now I am not 100% what this is but I sort of know that it is something to do with memory performance - is this correct? So should I go for this version do you think? Do I just need to reformat cache and data with in TWRP?
