I love this ROM, but the UI is very laggy. It's much more snappy on crDroid, but that one has a myriad of problems.

I wonder if this this ROM could benefit from overclocking the GPU. There's a commit for the kernel source here:

I saw that aaopt had put up a new build, 20181104, and dirty flashed with pico gapps as usual, and the build seems pretty solid. I had last been on the 10180708 build, which had random reboot issues.

So far all my pre-existing apps seem to work ok, but I have an issue with Play Movies - all of the films I've tried, return "Unsupported video format", and fail to play. Youtube videos appear to work, and a knittinghelp video reference app also works. Looking at a logcat, it appears to be the Widevine drm issue with google play. I thought play movies previously worked on earlier builds.

Hi and thanks so much for that updated ROM!

I got one question: I noticed the device suddenly starting the camera when handling it around. Is this some feature of the ROM that I can deactivate, e. g. a tap to wake or something like that? Or is it my nexus getting old? :confused:
[Nexus 7 Android Development] scruffy1:
late to this party, but having discovered the beauty of lineage on my ancient xperia sp phone, i was up for a try

i recognise the pedigree, having been first exposed to custom roms courtesy of a cyanogenmod based one that came pre-installed on my first tf300t, which set me on the path to learning how to jailbreak and mod

loaded the nexus 7 today with :

lineage-14.1-20171122_224807-UNOFFICIAL-aaopt-grouper

open_gapps-arm-7.1-pico-20190106

using twrp-3.2.1-0-grouper as the recovery

absolutely no issues whatsoever in having it work from the get go

impressive ! it seems to have completely disappeared the problems i was getting with the aosp (aosp_grouper-7.1.2-ota-eng-20180409.ds) in sending media via bluetooth, where the transmission often got distortion after a hour or so - i have no idea why that was the case, but it isn't now

perhaps a newer version of the aosp would do that too ?

it is way faster than the aosp,; again maybe it's just a newer build, but lineage has been amazing on the xperia too

major thanks to aaopt :good:

this one's a keeper ! :D
[Nexus 7 Android Development] rowley birkin qc:
New version.

There is a new release of the ROM by aaopt. It"s the 20181209 build.

Hi,

I wonder if it's possible to move from this Mod to AndDiSa's AOSP 7 builds (or reverse) without wiping data?

I couldn't find a list with differences between those Mods. Is there something?

Best regards,

Andreas
[Nexus 7 Android Development] AndDiSa:
This ROM is based on Lineage the other one is based on AOSP. Even if most of the parts work similarly especially settings and settings related apps are quite different. Due to that you will get a very unstable and most likely not fully working system if you switch between them without wiping.
[Nexus 7 Android Development] a.mair:
How could I miss that detail? :o Thanks!

Regards,

Andreas
[Nexus 7 Android Development] Publicorderkeeper:
Many thanks for latest update. There are no bugs or errors detected. Just one important question for me: is it possible to flash some custom core in order to overclock cpu and GPU. I am afraid of doing some experiments. And if there is 100% working custom core, inform me, please).
[Nexus 7 Android Development] Flounderist:
Try the kernel I posted on page 71 in this thread. :svetius:
[Nexus 7 Android Development] Publicorderkeeper:
What about GPU or only CPU can be accessed? And, could I flash it via TWRP?
[Nexus 7 Android Development] Flounderist:
Flash it as a boot image from twrp. Take a backup before.

Be careful you will need to reflash magisk after that, if any.

CPU details are tweakable using kernel adiutor or any other similar app.
[Nexus 7 Android Development] Publicorderkeeper:
I can increase up to 1700 MHz but only 1500 MHz works. Is it correct?
[Nexus 7 Android Development] Flounderist:
To be honest I don't know. I played around it a few months ago but at the moment device is running on AOSP, so I can't test it.

Give a try and after some usage check kernel adiutor stats.
[Nexus 7 Android Development] Publicorderkeeper:
After some tests have been done: yes, it is only 1500 MHz maximum...

And what AOSP do you use exactly?
[Nexus 7 Android Development] Flounderist:
If you search in forum you can easily find it :cowboy:

I don't think this kernel would boot on AOSP ROM, by the way.

Try it at your own risk after a clean flash, if needed.
[Nexus 7 Android Development] PTuT:
Hello.

Maybe someone could help me with an issue. When I open Gallery, it will give me an error message "No storage: No external storage available" and I can only cancel it and then the application closes. In that moment when error message shows up, I can see in the grayed-out background pictures that were taken with camera but I cannot get there as by clicking Cancel, the app will close. This issue I experienced with several previous ROM updated. Thanks for help.

And thanks OP for creating this ROM and keeping our aging devices current.

Oreo?

I've got a nexus 7 2012 started out with talapia but put grouper on it as I didn't need the phone support. It's running 7.1-r24 and I am wondering if this tablet will get an unofficial Oreo and if so if there are any known issues?

[Nexus 7 Android Development] Sir Charles82:
[MENTION=4990379]tech927[/MENTION]: as stated multiple times in this thread, it seems nearly impossible to port Oreo to our N7 (2012)...and as LOS 14.1 was dropped (no further development), I guess, this is the end on development for our device.

As long as AndDiSa has the device, there is hope (and Updates) for our N7'12! :svetius:

[Nexus 7 Android Development] xeropressence:
Having a bit of a strange issue here. I installed lineage-14.1-20181209-UNOFFICIAL-aaopt-grouper.zip, along with open_gapps-arm-7.1-pico-20190321.zip without issue. But I have noticed that if I tap the screen while it is disabled, it will bring it up to the unlock screen. If I swipe my finger across the display while it is disabled it will open the camera app. I tried adjusting a few settings and found disabling "Jump to camera" would stop the slide behavior from opening the camera but not turning on the display. Has anyone else encountered this, found a resolution?

Edit:

Nevermind, looks like "Tap to Wake" was enabled, unsure if I bumped that on accidentally or if its on by default.

I flashed my N7 with LN14.1 build 20180625-UNOFFICIAL, everything seems to work fine, except I am not able to get the N7 to connect to my Win10 PC over USB as an MTP device, or for ADB access (although ADB over WiFi works fine).

Any suggestion is appreciated.

TIA.
[Nexus 7 Android Development] cucumbers:
Don't know if this will help you any, but I have never been able to connect my N7 to my PC (Win7/10) unless it's in Recovery mode. Annoying but at least I know it works for sure in Recovery.
[Nexus 7 Android Development] digixmax:
Thanks, USB access in Recovery mode works!!!

I should note that I couldn't connect my N7 running stock ROM to my Win10 PC over USB either. However, it could connect just fine to my Linux laptop which enabled me to use Linux ADB to flash TWRP to it.
[Nexus 7 Android Development] digixmax:
I am currently using build 20180625-UNOFFICIAL.

Is it worth upgrading to either of the later build 20181016-UNOFFICIAL or 20181209-UNOFFICIAL-aaopt?

My N7 does not wake up or go dormant when I open or close its cover.

Is there a setting that controls this behavior?
[Nexus 7 Android Development] cucumbers:
Not sure about benefits, but I certainly didn't experience any drawbacks when I went to 20181209.

No idea about the cover, never even tried that...
[Nexus 7 Android Development] digixmax:
Do I need to wipe /system and /data to go from build 20180625-UNOFFICIAL to an aaopt's build such as 20181209-UNOFFICIAL-aaopt?

I got an error 7 when I did a dirty-flash.
[Nexus 7 Android Development] cucumbers:
I don't remember needing to... but I also don't remember at which point I switched to aaopt builds, it's been a while. So maybe?

Mind you, I always flash cache and Dalvik before AND after flashing ROMs. No idea if it would help you, but you can try.
[Nexus 7 Android Development] aaopt:
Wipe system, don't wipe data.
[Nexus 7 Android Development] digixmax:
I tried wiping /system, still got the same error "Can't install this package on top of incompatible data. Please try another package or run a factory reset".

Also, I got the same error when I tried to flash build 20181016-UNOFFICIAL-grouper.

UPDATE

I decided to follow the suggestion in the error diagnostic message "to run a factory reset" and wiped /data in addition to /system, and was able to flash 20181209-UNOFFICIAL-aaopt successfully.

Last night I undusted my Nexus 7 Nakasi-Grouper Stock. No apps installed about 5 years without using it. I remembered why I throw it away in the attic, was totally unresponsive slow af unusable. Anyways I found this thread and decided to give it a try. Now I have a totally resurrected Nexus Tablet working properly and pretty responsive for a 7 years old and obsolete device.

I remove the virginity of it by unlocking the bootloader then flashed TWRP 3.3.0, then flashed this ROM (Lineage OS), opengapps pico (arm), then flashed Magisk 18 to root it.. Not a single issue (I flashed it all in one go) now I have a new tablet for a YouTube, reading, browsing, and light gaming. I'm happy with results.

My N7 is running lineage-14.1-20181209-UNOFFICIAL-aaopt-grouper with addonsu-16.0-arm-signed installed.

Has any one run into this issue with Greenify or some other app, and has found a solution?

TIA.
[Nexus 7 Android Development] Dggrr:
I don't think so, I followed the recipe at https://xdaforums.com/showpost.php?p=70352834&postcount=3.
[Nexus 7 Android Development] Charles IV:
go to settings, developer options (i assume you know how to enable them) and find something like 'root access', clock on it, and so if it gives you an apps only or apps or adb option.

reason for asking is [MENTION=3729448]aaopt[/MENTION] added something to the source code to include root in the build, rather than having to flash the zip.
[Nexus 7 Android Development] Dggrr:
Yes, there is a Root Access item in Developer Options, that give a dialog with Disabled|Apps only|ADB only|"Apps and ADB"

:)
[Nexus 7 Android Development] Charles IV:
[MENTION=3729448]aaopt[/MENTION], i was looking at the local manifest folder, and i noticed that you were using AndDiSa's 7.0.1 kernel, rather than 7.1.0, is there a reason for this, i would have thought that you would have needed to use the 7.1.0 kernel, because it is lineage os 14.1, rather than 14.
[Nexus 7 Android Development] aaopt:
Good catch. I don't think he created the new branch right away when switching to 7.0.1 and then I just never realized that I hadn't switched to it. So my 20170122 build does not include his latest kernel changes even though I thought it did but hopefully my next one will.
[Nexus 7 Android Development] AndDiSa:
The 7.0.1 kernel works for 7.1, too. I was playing around with some patches on the 7.0.1 branch which messed it up a bit, so I decided to switch to 7.1.0. Future development will take place on 7.1.0 though.
[Nexus 7 Android Development] micw:
Hi,

great to see that my good old Nexus 7 is still supported :)

Do you have the 3G baseband wakelock patch in the kernel? This is needed by tilapia version because otherwise battery will be empty within <24h (with patch battery is good for >7 days idle).

Patch (it was for MM kernel): https://github.com/micw/cyanogenmod_kernel_grouper/commit/959e3e1e21c61a741a07ed1d5196f091b9e01ab9

Great ROM - Thank you for returning life to my tired Nexus 7

Actually signed up to XDA to thank aaopt - and anyone else involved for this ROM.

After trying several other ROM's in an attempt to breath some life back into my tired old Nexus - I found this one - and Viola ! It just works . . .

Thank you so much guys for putting the pep back into my tired old Tablet ! Everything seems to work . . .

Just followed the instructions in the first post . . . used "lineage-14.1-20170122-UNOFFICIAL-aaopt-grouper.zip" - with open gapps pico - and the gapps-config - installed without any hassles . . .

Thanks again guys . . .
[Nexus 7 Android Development] abhifx:
while you are at it why not add usb charging in OTG mode. that should be good for car installs
[Nexus 7 Android Development] AndDiSa:
[MENTION=3692487]abhifx[/MENTION] I'd already included the patch but removed it again. I had the impression that the system used more battery and was less performing so I reverted it back. Those trials were one of the reasons I started branch 7.1.0. Probably I'll create a dev-branch having this patch included so people can do test by themselves.
[Nexus 7 Android Development] Charles IV:
Yes, from reading up about it before, I was doubtful it would work, but it will be interesting to see what effect it has, if any. Anything to get my tablet charging quickly again :)

(I know undervolting works from when I was running lollipop, but if anyone can lead me in the direction of how to undervolt using the defconfig file, I will be grateful.)
[Nexus 7 Android Development] abhifx:
seems like a good idea, this way we can test battery drainage.
[Nexus 7 Android Development] :
I've just flashed* (using TWRP) the 20170122 version over 20170108. All went well, lovely new boot animation :)

How do I get into developer options? The usual 7 taps on build doesn't do it. I've restored back for now as I was getting some settings crash (e.g. sound)

*Edit: I didn't dirty flash, I wiped partitions as per instructions before flashing.
[Nexus 7 Android Development] Chuck Jones:
I want to upgrade my poor old Nexus 7 (2012) so badly, it runs so frickin slow on 5.1.1.

But I am a complete newb when it come to what is necessary to do the upgrade to Lineage OS 7.1.1.

Is there any documentation, procedure, step-by-step instructions on how to do the upgrade?

And don't assume I know what you mean on certain steps, please.

I have rooted my Zte Avail 2, with success, but that was with a tool that did all the work for me.

I did install SuperSU, and other tools to verify it was rooted.

I really liked my Nexus 7 (2012), but Lollipop ruined it.
[Nexus 7 Android Development] :
A note re battery life; I was running version 20170108 and it seemed hungry. 25% usage in an hour simply web browsing, so predominantly display.

I restored version 20170101 to see if it is less hungry.
[Nexus 7 Android Development] Charles IV:
First your bootloader needs to be unlocked (an unlocked padlock symbol when booting up) but it is likely it is, if you are rooted, it is.

If your bootloader isn't unlocked, I recommend the Nexus root toolkit. Google it either way.

If your bootloader is unlocked, make sure you have twrp, (this can also be done via the root toolkit) and then on twrp, backup, everything via twrp, and another way like zip me (on the play store) or titanium backup to restore apps etc. Then wipe data, system cache and dalvik, not internal storage, otherwise you delete the backups.

Once you have done that download the open gapps, the ROM and the gapps config file. Then flash the ROM, and add the gapps to the zip queue. And boot up. Booting up will take a long time every rule you've just flashed a ROM.

Sorry, because the last bit is basically what aaopt said in the OP, and sorry if it was a bit basic for you.

---------- Post added at 09:24 AM ---------- Previous post was at 09:22 AM ----------

If a kernel is made with undervolting, (or Googleing helps me find out how to) that helps. :)

Otherwise I would expect this to be normal, especially for our tablets battery

---------- Post added at 09:28 AM ---------- Previous post was at 09:24 AM ----------

If you flash back, check if it's already enabled.
[Nexus 7 Android Development] :
I never change/modify the kernel (I'm not that clever!) so it will be exactly as it is on the version I've installed. Is there a kernel difference between versions 20170108 and 20170101?

I restored back (I always backup before flashing a new version or ROM) and it was enabled. I always run my Nexus 7 rooted and with developer options.

Thank you for your replies. :)
[Nexus 7 Android Development] Charles IV:
Sorry, you misunderstood me a bit.

I meant if you reflash the newer version of the ROM
[Nexus 7 Android Development] :
Ok, understood. Did that and I got developer options. Thanks :good:

Odd thing is though, on the previous flash, I didn't get the setup wizard. Second time, I flashed with pico gapps and got the google (I presume) set up wizard but it was giving me errors. So I reflashed just the ROM and got the Lineage set up wizard - that went through ok. THEN I flashed pico gapps.

However, I'm getting random crashes in many apps and the sound settings always crashes. WiFi is also unstable and drops connection. I've restored back to a previous version of the ROM. I'm going to stay with this for a bit but I might go back to AndDiSa's ROM. Whilst I like the extra configurability of LineageOS there's nothing that's a 'must' for me. :)

I'm starting to think that the best, and fairest way, to test any ROM - even when simply upgrading the version - is do a complete and clean install.
[Nexus 7 Android Development] Pich018:
Have you actived root in developer mode's option ?
[Nexus 7 Android Development] digixmax:
Yes I did enable root-access in Developer Option settings -- I should have mentioned that my other apps such as FX file-manager got root-access just fine, hence the mystery.
[Nexus 7 Android Development] uphall:
Connect to PC.

It's a PITA is it not. I had the same problem but found a workaround.

Change the connection mode to PTP.

In windows 10 you should see the Nexus 7 in the drives section (I set mine to open automatically). When opened you will be presented with a DCIM and Pictures folders..

Copy your files to inside the Pictures folder.

On your device, using your file explorer, navigate to the Pictures folder and the copied file should be there.

Copy it to it's final destination and delete the original file in the Pictures folder.

Hope this helps.
