[Nexus 7 Android Development] acidspider:
Can we make this rom faster and convert to f2fs. Is it compatible?
[Nexus 7 Android Development] golden-guy:
We might. I merged the f2fs commits into Omni grouper kernel but have yet to debug boot loop with these. If f2fs is important for you, feel free to flash an alternative kernel.
[Nexus 7 Android Development] acidspider:
I tried flashing m kernel but couldnt get it to boot. Been a while sincw i played with tablet properly. Need to refresh my memory how
[Nexus 7 Android Development] hochoch:
From my post earlier in the thread: [quote name="oswald-p" post=63303787]I am using the a69 version of the M Kernel that works great with omnirom.<br />

<br />

O-p[/QUOTE]<br />

<br />

So, I installed this today and it would not boot after flashing (i'm on data/cache f2fs). i thought i'd try a68 or maybe to back to ext4, but after reading through the m-kernel thread someone suggested rolling back twrp to 2.8.3.0. I have it a shot, flashed everything again, including a-69 and it started right up! If anyone else has a similar issue try the old twrp! Not sure how you got it working, but I have always had trouble flashing new kernels......wondering if it's been a twrp issue all along.
[Nexus 7 Android Development] acidspider:
Confirmed working.. Twrp 2.8.3 and m kernel a69. As above on f2fs. ?
[Nexus 7 Android Development] Sisqo:
Flashed it 2 days ago, great rom no problems so far.
[Nexus 7 Android Development] Eezay:
Hi, after having problems with marshmallow and lollipop roms on this device I converted back to 4.4.4 by installing OmniRom. Running very smooth so far, much better than lp or mm.

Now I want to install xposed. Can you say what version we can use for this rom? Maybe give a link? I want to run Art runtime.
[Nexus 7 Android Development] Ammar_Hamdan:
Amazing ROM... Performance+ good battery life + a lot of features!!

P.s coming from stock 4.4.4 and I can say this ROM is way better!
[Nexus 7 Android Development] Serrano-9195:
Many thanks for all the efforts to create this great ROM...
[Nexus 7 Android Development] outcubus:
[MENTION=5473651]golden-guy[/MENTION] thanks for this amazing Rom. I was using lollipop but all roms are lagging a lot. With your rom I can use my nexus again.

I've seen here that some people are using this rom with f2fs, is there any real difference? I've never used f2fs. How can I use this rom with f2fs? (just for testing if it's faster).

Thanks a lot.
[Nexus 7 Android Development] Takinato:
Is so nice to be able to use my nexus again, thank you so much Omni Rom!!!
[Nexus 7 Android Development] hollisnh:
Any kernel suggestions to pair up with this great rom?
[Nexus 7 Android Development] DJB628:
Looks like I will have to give this Rom a go, I am running a Grouper MM Rom right now and works great, until I start browsing the net, then I get lockups, not matter which browser I try. You figure a basic feature as browsing should be easy, but doesn't seem so. I also am using only the Nano Gapps, so it is not a space issue, and I only have a total of 40 apps installed.

So I would like to know from those of you using this Rom, browsing is not an issue ?? Please advise, and if you are using a specific browser app.
[Nexus 7 Android Development] hollisnh:
No issues at all browsing in any browser I tried (native, Firefox, mini Opera).

I got fed up with 30sec-2min lockups using LP and MM Roms, this really made it useful tablet once again.

Highly recommend this ROM with F2FS /cache and /data plus M-Kernel A69 version.
[Nexus 7 Android Development] DJB628:
Thanks for the update, what is the advantage of flashing the F2FS ?? and is it needed ?? is the stock kernel fine, or is the M Kernel better
[Nexus 7 Android Development] rneteoriteflo:
Great rom! Very stable and smooth. Just one thing, for some reason when I leave it and the screen shuts off. I'm assuming it goes into sleep mode, but every time it does this it turns off completely and I would need to hold the power button again to turn it on. Any tips on why would it do this?
[Nexus 7 Android Development] hollisnh:
F2FS is a file system, its supposedly about 30% more efficient than stock file system EXT3. You would need to use TWRP 2.8.3.0 to format /Cache and /Data partitions along with a kernel that is compatible with F2FS, such as M Kernel A69 version. Yes, its wipe all internal storage so have a OTG USB stick handy with kernel and backup just in case.
[Nexus 7 Android Development] golden-guy:
Never had that, best provide a logcat so that I can have a look at.
[Nexus 7 Android Development] DJB628:
I'm not on this ROM as of yet, but I will be, but I was also getting this same issue on a MM issue, and also with the stock Rom. So my guess is it is either a kernel issue, or we just have a batch of devices that have this same issue. When I install this ROM, I'll report back and let you know if it happens to me also on this ROM, as it is definitely happening on the MM Rom I'm on. I also get the lockup when the tablet has been in the charger for a while, and then I go to wake the device up, it takes forever to respond, then after awhile is works. ;)

Hi guys, I was on a custom 5.1 rom.

I wipe cache, dalvik and system, then I flashed this rom with google app and SuperSU all in one time. When I press reboot button, twrp said me "no os detected" so before rebooting, I reflashed the rom.

But now, on reboot, I am stuck on Omni logo for more than 10 minutes.

What is the problem ?
[Nexus 7 Android Development] golden-guy:
ROM only supports ext4, re-format partitions in TWRP before flashing.
[Nexus 7 Android Development] Marcovanbasten:
I just got back to TWRP and while wiping it is writter "formating system using make_ex4fs function"
[Nexus 7 Android Development] golden-guy:
Be sure to re-format /system, /data and /cache back to ext4. While your recovery might be fine with them on f2fs, the ROM isn't. Alternatively, you might as well flash a f2fs enabled kernel.
[Nexus 7 Android Development] Roosterno1:
I've tried a few ROMs on my '7 and have literally thrown it across the room.

This ROM has brought life back to the old girl !

had an issue with chrome browser not wanting to login, but I left it overnight and after a few updates to the Google packages, it all working slippy smooth..

Many thanks ?
[Nexus 7 Android Development] Drake008:
I have this rom for about 2 months now.

There is one big problem. It slows down after some hours of "hibernating". After a complete reboot everything is fast again.

Is this a known problem and can I resolve this problem?
[Nexus 7 Android Development] golden-guy:
Not for me and I am using this ROM since last year. Sounds setup related, you might want to try with a fresh install.
[Nexus 7 Android Development] conduisant:
still a very good ROM, just flash on my old Nexus 2012 and this ROM is pretty smooth !!!

thanks a lot !
[Nexus 7 Android Development] N72012:
Tablet stuck on OmniROM splash screen after flashing

I have flashed omni-4.4.4-20151122-grouper-HOMEMADE and the micro GApps package recommended in the opening post. The installer appeared to run fine for both of these.

However when I try and boot up the device, it get's stuck on the OmniROM splash screen. The eyes blink and the ears wiggle and that's it, it just stays there.

What could be the possible causes?

Other possibly useful information:

The bootloader was already unlocked

I have installed a Clockwork Mod recovery (version 6.x)

I previously had a Cyanogen Mod ROM installed (Lollipop)

The battery is at around 25% charge

P.S. Thanks Golden Guy for your good work

EDIT: Looks like it is behaving now, the apps are being optimised. Could possibly have been the battery charge level that was the issue.
[Nexus 7 Android Development] gigitek:
Hello guys, I need some help flashing this ROM. I'm on stock android 5.1.1

What are the instructions that I need to follow to flash this ROM ? Some steps that I need to follow, links etc

I'm not familiar with OmniROM and I haven't seen instructions in the first posts... Some help is more than welcomed.

Thanks for your help !
[Nexus 7 Android Development] golden-guy:
Unlock bootloader

Flash TWRP recovery

Flash ROM zip and Gapps

If unsure about any of these steps, use the search for further info

Thanks for the rom.

After a couple of months of lags on Nougat, think it's better to come back on 4.4.4 . My tablet feels the way it should!

Are people here using a custom kernel or is it more than ok on stock?

Thanks!
[Nexus 7 Android Development] K-Project:
Just wanted to post up a massive thank you for this rom. I've been struggling for some time on the stock 5.1.1 but today decided enough was enough. Been shying away from it for too long, and the device, while not the fastest, had been much better some versions ago.

I'd worried it might be the hardware, but after installing OmniROM, all worries gone. Working fantastically well right now and I'm thrilled I don't have to buy a new device. THANKYOUTHANKYOUTHANKYOUTHANKYOU!

EDIT:

Spent an evening and the morning now absolutely hammering the tablet with all the stuff I usually do on it - lots of gaming, video, casting messaging etc, etc. Not a beat dropped! It's like having a new device. I cannot thank you enough, and if you are reading this with an old Nexus 7 that needs new life - THIS IS THE ROM TO USE! Will definitely donate. :)
[Nexus 7 Android Development] golden-guy:
Glad that you like it :)

As you mentioned, feel free to donate to the OmniROM project: https://www.omnirom.org/donate
[Nexus 7 Android Development] K-Project:
Like it? It's completely rejuvenated this old tablet. It is like new again. I love it! Flashed both of our Nexus 7's now with this ROM. It is superb.

Done. :good:

[Nexus 7 Android Development] K-Project:
Wow, fantastic! Thanks for the update.

I'm pretty new to flashing Android tablets. I've just got mine set up as I like it with your previous release. Can this be flashed "on top of" the existing installation without issues or should it be clean installed? Thanks.

Plus, this ROM is amazing. I'm with the guy earlier who said he didn't understand why this thread wasn't more active. I suspect two things: one being that the ROM works so well that no one has to post back with issues. Two being that I imagine many users will perceive 4.4.4 as a step back. What a shame when it runs so incredibly well.
[Nexus 7 Android Development] golden-guy:
You can for sure flash it on top, no need to install clean. :)
[Nexus 7 Android Development] tamilkhadar01:
I flashed it. No issues except some kind of stuttering while scrolling in apps
[Nexus 7 Android Development] K-Project:
I assume you must be using Nova Launcher as I am? I had the same issue. There's a simple tickbox in the tablet settings that stops it. I'm pretty sure it's in Settings/Animation Control/ListView Animation. Turn this OFF. I'm sure that's how I fixed it.

Anyhoo, flashed both of our Nexus 7's with the update. Looking good so far. :)
[Nexus 7 Android Development] tamilkhadar01:
I am not using Nova launcher. Anyhow I will try to adjust the settings as you mentioned. Thank you
[Nexus 7 Android Development] Lordka:
I bought an used N7 2012, updated to the latest official KitKat rooted it, and noticed that the offline charging wasn't working.

So I installed the latest TWRP, flashed the latest OmniROM and gapps and still I have no offline charging it just boots when the charger is plugged.

I have search the forum but it seems i'm the only one with this problem..

Any help on how can I fix this issue?

Thanks
[Nexus 7 Android Development] golden-guy:
Eventually the previous owner had disabled off-mode charging. To re-enable, reboot to bootloader, connect the device to your PC, and type this command:

fastboot oem off-mode-charge 1
[Nexus 7 Android Development] Lordka:
Thanks for the reply, but it didn't fix the issue.

[lordka@bart:~ ] $ fastboot oem off-mode-charge 1
...
(bootloader) Charging Mode is already enabled!
OKAY [ 0.020s]
finished. total time: 0.020s

Any pointer on where should i look to find the problem? Thanks
[Nexus 7 Android Development] tamilkhadar01:

[Nexus 7 Android Development] golden-guy:
What's the version of your boot loader? Can you post the output of cat /proc/cmdline with cable plugged and device getting switched on.

[Nexus 7 Android Development] golden-guy:
Having looked at it: On kernel level, the offline charging mechanism only gets triggered when the device gets powered off with cable plugged in. That way it should still work for you. That's a restriction in combination with the bootloader for this device, so it cannot be fixed afaik.
[Nexus 7 Android Development] fencerxx:
Hi [MENTION=5473651]golden-guy[/MENTION] ! first of all I would like to thank you for your work with this ROM. I want to try it and bring back to life my grouper.

I have some questions, though because I don't do flashing often and I forget:

1. If I flash the ROM as it is, the Kernel is also flashed, right? Which partitions have to be in which format?

2. I have TWRP 3.0.2-0, do I need to rollback to 2.8.3.0 in order to flash this ROM?

3. How can I know what partition format type I have in cache/data?

4. How can I format to f2fs?

5. If I decide to format f2fs, which partitions necessarily need to be formatted? (assuming I'm going to use m kernel a69 aswell)

Thanks!
[Nexus 7 Android Development] Lordka:
Fixed. Downloaded a factory image from google with the latest bootloader flashed it and now I have offline charging. Thanks
[Nexus 7 Android Development] K-Project:
Please accept my apologies. I think we were at cross purposes.

I'd experienced an issue with text scrolling, and hadn't noticed that I'd accidentally enabled this feature. And of course, disabling it fixed the issue for me, but my issue is clearly not the same as yours. Again, my apologies.

What kind of scrolling problems are you experiencing? I have found this ROM to be absolutely perfect for this old device. The only one thing I have found is that if I play Zen Pinball I have to disable the "Enhanced" mode for Nvidia devices. I'm not sure what exactly this is supposed to enhance, but with it off the game looks and performs much better. All of my other games in my collection are performing exactly as they should without user changes.
[Nexus 7 Android Development] tamilkhadar01:
What is my observation is whenever I use the apps other than Google apps, there is no lagging while scrolling up and down. But while using Google apps like Google, gmail and YouTube there is always lagging. They don't feel smoother. I don't know whether it is the problem with the gapps package or not
[Nexus 7 Android Development] golden-guy:
If you want f2fs on /cache and /data, reformat in twrp and install rom and afterwards that kernel. Otherwise, just flash the ROM. The kernel is included.
[Nexus 7 Android Development] K-Project:
Hmm, disregarding the fact that of course this tablet is not the fastest one these days, I have to say I've had no particularly noticeable issues with lagging on any of the Google apps. They certainly used to on the Lollipop stock firmware but not really on this. If it helps, I'm using the nano package myself.
[Nexus 7 Android Development] tamilkhadar01:
I'm using pico, will try nano tonight:good:

[Nexus 7 Android Development] fencerxx:
I just flashed this ROM yesterday (no f2fs), and, coming from stock MM I can say there is a huge difference, the tablet is actually usable now.

I used pa_gapps_modular_micro, so far no problems.

Off charging works fine, no lag or stutter on any google app.

This is a great ROM, only CON is that some applications from the Play Store are not compatible with 4.4.4 such as Netflix. Other than that, it brought alive the tablet.
[Nexus 7 Android Development] K-Project:
Just checked, and the package I have installed is pa_gapps-modular-nano-4.4.4-20150410-signed.zip, from here.

Yes, but then you'll get this with the big apps like Netflix. They don't support any unlocked/rooted/flashed devices as far as I know. Nintendo are the same (sadly). I quite fancied a bit of Animal Crossing on my tablet! But overall for me, going back to 4.4.4 with OmniROM has given me way more than the downright rotten stock 5.1.1. I cannot believe that Google would do this, but then again they are becoming more like Microsoft all the time...
[Nexus 7 Android Development] golden-guy:
Having again played around with lowmemorykiller, I got the best results in terms of multitasking UI responsiveness using these minfree settings:

shell@grouper:/ # cat /sys/module/lowmemorykiller/parameters/minfree
15360,18432,21504,38400,46080,51200

Basically this setting tries to keep 200M of RAM free, as this old tab just seems to perform best with that much reserve left. This turned out to be a great improvement for both new and older installations :good:

For you to verify, open an adb shell, su to root and enter this command:

shell@grouper:/ # echo "15360,18432,21504,38400,46080,51200" > /sys/module/lowmemorykiller/parameters/minfree

Note that this will be reset upon reboot, unless you change it in ramdisk or use Kernel Adiutor app.

If there are no issues due to that change, I will add this as default for the next release.
[Nexus 7 Android Development] thoiloidainhan:
KK with OCT 17 patches who would have thought :). Thanks for the update. Is xposed working ??
[Nexus 7 Android Development] golden-guy:
Hehe, I already wondered when that question would come. :)

I made a fix for Xposed for Omni KK on S3 Mini, but haven't yet released a new build for Nexus 7 since then. If there's interest, I can do ofc.
[Nexus 7 Android Development] thoiloidainhan:
YES PLEASE!!!! :fingers-crossed::fingers-crossed::fingers-crossed:
[Nexus 7 Android Development] tamilkhadar01:
I clean flashed the ROM with PA gapps but still the problem persists with Google apps. But this time relatively better performance. Otherwise the ROM is superfluid.
[Nexus 7 Android Development] golden-guy:
New 4.4.4 build 20171105 is up!

I have uploaded a new build now with legacy Xposed support, plus the above mentioned lowmemory killer settings.

Based on this patch, I added a backport to Kitkat and guarded this code via additional build property. Which means, that this code will only run if this property is set (to 1).

dalvik.vm.xposed_whitelist_hack=1

Add this entry to your /data/local.prop file (create it, in case it does not exist yet) and reboot prior to Xposed installation.

Reason for that is, that only some people want to use Xposed while others don't. As this code circumvents a security mechanism (it has to, for Xposed to work) I decided to make this opt-in.

Enjoy! :good:
[Nexus 7 Android Development] thoiloidainhan:
Xposed is working great for the new update. Don't even know what do I need it for :confused: but options are good :laugh:

Anyone an idea what I can do to fix it??
[Nexus 7 Android Development] golden-guy:
Check for any f2fs formatted partition and re-format to ext4 in TWRP. Afterwards reinstall the ROM.
[Nexus 7 Android Development] tamilkhadar01:
You are right. I too had a similar problem and after reformatting the partition to ext4, the problem got solved.:)

Hello, I have CWM recovery 6.0.1.0 already loaded on my N7 and was wondering if I could flash this ROM without having to switch to TWRP? My poor nexus 7 has been sitting unused for quite a while as I've upgraded my phone and bought other tablets. I think it's about time to give it a refresh.

Hello OP! any chance you may port Android Go for N7? Would really give it a new life

I have been using your rom for a year now... it was fantastic for the most part but since the last few months it freezes so much (i expect it to be slow considering its age but it was never this bad) Clearing cache and dalvik didnt make any difference.

Planning to clean install the latest release. Is there anything I can try before I do that?

Thanks
[Nexus 7 Android Development] codlike:
I just wanted to send you a very big hug and thank you for keeping this updated.

my nexus 7 has been sitting on a shelf for at least two years with cm11 on, but I've tried this and while it will never be like greased lightning, is much smoother now and very usuable.

I wondered, if anyone has tried parrot mod with this, a) is parrot mod still relevant b) does it improve anything or is omni already tweaked.

*edit - got curious, flashed parrotmod - it did give a significant boost in smoothness and speed to Omni rom, but in upgrading the bluetooth, it breaks it, annoyingly.
