My working build workflow is public in post #3 for all to join the fun. Building for Tilapia would be better handled by someone who has the device. (That person would need a device tree for tilapia, which could be added to local manifests.)
[Nexus 7 Android Development] Charles IV:
This is the problem, I've got a device tree but no device to test it on, and no idea why it does doesn't work.

November patches are now integrated, along with a night light tile, when are you likely to build again? Seeing as my source isn't working, I'll run yours as I still want to update ;)

---------- Post added at 04:31 PM ---------- Previous post was at 04:28 PM ----------

I'm completely stumped, could you copy the log to the SD card and upload it?

Not that I'll able to get anything from it as it boots.

I'm interested in what [MENTION=2188693]AndDiSa[/MENTION] said, but I'm unsure of how to integrate it, and my source isn't working to build again anyway.

This is what TWRP dropped to sdcard:

Thanks for the info (I've seen your post #3 already) but unfortunately I've neither the needed foreknowledge nor the time to learn such tings. But I agree thats impractical to build a rom for an 'unknown' device you don't have access to. :crying:
[Nexus 7 Android Development] sjrmac:
I was trying to download the ROM via the tablet and it seems like it fails due to the device not having an SD Card. Sorry if this is repeated, but is there a way to download without an SD card through like Google chrome, etc?
[Nexus 7 Android Development] andynroid:
Google it and as an alternative use Mozilla
[Nexus 7 Android Development] Flounderist:
Hi there, ,I just flashed latest build.

It looks smoother than the previous one.

I will test it and report bugs, if any.
[Nexus 7 Android Development] Charles IV:
unfortunately, I have no idea, and at this point have given up.

If you wanted, you could try my grouper build and see if it booted, but it doesn't matter.

as people have said, nice and smooth.

Also you forgot my commit about the lockscreen etc.

(just want to be in the changelog!)
[Nexus 7 Android Development] sjrmac:
On this latest build, would you mind checking ADIA64 app under the battery tab? Not sure if my battery is going bad or that the ROM registered less battery capacity. Uploaded a photo as well to show it on this post.
[Nexus 7 Android Development] Flounderist:
It might be a bug.

See screenshot, sorry for posting it in Italian, but it is self-explanatory :D
[Nexus 7 Android Development] sjrmac:
It may be kernel side, I'll have to check it out, was wondering yesterday why my first day with this tablet was dying quicker than I thought :)
[Nexus 7 Android Development] frantisek.nesveda:
I think there is some issue with the SELinux contexts, I think, to fix either open a Terminal emulator app or connect with adb shell and run:

su
restorecon -FR /data/media/0

That should fix the problem.
[Nexus 7 Android Development] Mr Smile:
Anyway, thanks for your efforts. :good:

I'll for now stick to aaopt's builds. It is very impressive how judder-free our old tablets run with it. (I have to say that I did not install gapps as I don't need the functionality)

If anybody wants me to test a tilapia build, just ask! :highfive:
[Nexus 7 Android Development] Mr.Speedy™:
Problems with download.

Hi guys. Can someone upload files to google drive? In my country androidfilehost blocked. Someone can say that ROM have root?
[Nexus 7 Android Development] Flounderist:
ROM has inbuilt root. You can enable it from dev options. You can also flash magisk on top of it and enable root from it.

You can download latest build from my drive.

https://drive.google.com/file/d/1SMipg3EllkvjZ33djKUiiiPz3fKQlNVl/view?usp=drivesdk
[Nexus 7 Android Development] Seferi:
Installed the latest test build yesterday. Its definitely smoother. Fantastic battery life as well.. Thanks for the great work mate!
[Nexus 7 Android Development] p7810456:
I have installed this ROM on my Nexus 7, but charging is very finicky. It doesn't detect when most chargers are plugged in and when it does, it charges very slowly. I have wiped the cache many times,and it always works once after rebooting afterwards. Is there a fix for this or do I need to flash another ROM? Thanks in advance!
[Nexus 7 Android Development] cloppy007:
I get a high idle cpu usage (25-50%) with this version as well as with 20171020. It wasn't there with 20170717. Do you know what can cause this?

Besides that, when I open the stock file manager, the MTP host crashes (with all three versions of this rom I've tried). Is that expected?

Thanks for your effort!
[Nexus 7 Android Development] rockuman_ex:
finally flashed my 5 years old Nexus 7 with this rom.

Wow... the speed!

one thing I noticed, double tap to sleep or wake doesn't work?
[Nexus 7 Android Development] sjrmac:
It seemed to work for me, not sure, can be different for everyone and depends on how their devices handle the ROM, etc.
[Nexus 7 Android Development] rockuman_ex:
mine is the wifi version and i flashed the 07/2017 version

Do i have to flash to the latest version? And can i do a dirty flash?
[Nexus 7 Android Development] sjrmac:
I usually wipe after a bit and do a clean install on the latest builds available, then slowly update here and there for a while. That's what I do with every device as cleanup is good, especially on older devices, haven't had my Nexus 7 long enough to do it year but that's a pattern I recommend to keep it going well :)
[Nexus 7 Android Development] JT1510365:
currently running the november 22nd build in multirom for my nexus 7 2012 and it runs pretty good. You cant expect this rom to be perfect because our nexus 7 was made in 2012 and has old hardware and huge thanks to the developer (OP) for bringing us a lineageos 14.1 rom which runs ok for me. Yeah it might have lag but im still able to get things done with the rom and i use this rom as a secondary rom in multirom. Huge huge thanks your work is appreciated as i understand how hard it is to port roms to old devices. A few suggestions i have is can you remove live display all together i cant use it because it creates massive lag so in my opinion it would be good to remove it all together:) Also i think if you use cyanogen gallery the green effect is not there i have to test it first so i will let you know about that. Also is there a way to add the status bar date option from rr remix i can do it myself with decompiling if you tell me the code or if you could give me a flashable zip that would be great. Anyways thanks for your work im a learning dev too and if you need help on anything just ask:)
[Nexus 7 Android Development] hackintosh5:
Disable it. Had error on previous phone lineagos, disable app from settings had NO negative impact, anywhere.
[Nexus 7 Android Development] cloppy007:
Just did it, the error msg went away, thanks!

Any clue regarding the cpu usage?
[Nexus 7 Android Development] MrHaroldA:
I rooted and flashed my daughter's Nexus 7 tablet today, and I'm impressed!!! It was barely usable before, and it's bleeding fast again! :D

The only thing not working now is Netflix. I've installed the latest beta of Magisk (14.5), but it fails to pass the SafetyNet tests, while my Nexus 5 passes them just fine.

Anybody here with a working Magisk/SafetyNet/Netflix setup?
[Nexus 7 Android Development] abhifx:
that is going to be difficult due to kernel version being very low on our device.

Just tried it as i need to download a textbook PDF and it failed again on latest build due to "no SD card"

Anyone else having issues with this?

Sam [MENTION=3729448]aaopt[/MENTION]
[Nexus 7 Android Development] MrHaroldA:
Yep: "proc_monitor: Your kernel doesn't support mount namespace".

Are there any custom kernels for the N7 that have this compiled in?
[Nexus 7 Android Development] dnaod:
I reached out to Netflix support on Twitter and they directed me to a pre-Download feature version of Netflix that they host. I've been using that APK. If you need the download feature, you'll need to get Magisk working.
[Nexus 7 Android Development] ambyy:
This ROM is great but I have a serious concern with swiping up to unlock the device. Sometimes i have to swipe up to 5 times before it unlocks.
[Nexus 7 Android Development] aaopt:
Are you still on the July version from OP? That issue's supposedly fixed in the testing versions. If you're on one of the November builds then we need to know that the fix didn't work for you.
[Nexus 7 Android Development] ambyy:
Oh! I think I am on the July build

Thanks a lot for keeping the work going on !
[Nexus 7 Android Development] frantisek.nesveda:
I had the same issue last week and doing the restorecon thing worked for me. Did you reboot afterwards? I'm not sure if that was necessary or not, I think I rebooted and then it worked.
[Nexus 7 Android Development] fsw_informatrix:
[MENTION=4971738]ambyy[/MENTION] : I have always dirty flashed this ROM without trouble for now.

Anybody elses deb not recognizing their SIM card? This has been happening on the last couple of builds, too. Reboots and even reflashes don't seem to help.
[Nexus 7 Android Development] scottysau:
Now I'm lost. Grouper doesn't have a SIM card. Tilapia does. Is these build for both devices.
[Nexus 7 Android Development] MrHaroldA:
Grouper is Wifi only ...
[Nexus 7 Android Development] scottysau:
Okay MTP keeps crashing, and has been for a long time. Still have 3 of these and one Tilapia also that a ROM would be handy for.

Find attached catlog set at verbose level. Latest build, pico gapps and magisk, so I access the logs.

Appreciate your work

Just a side note: TWRP has been updated to version 3.2.0.0. Download at

https://dl.twrp.me/grouper/

I used Official TWRP App from Play Store to successfully flash recovery on my Nexus 7 (2012) WiFi.
[Nexus 7 Android Development] Flounderist:
Already flashed. I found that recovery hangs a little longer on splash screen, but nothing special to be mentioned.
[Nexus 7 Android Development] eldani82:
Hey. I registered here to thank the OP for this ROM.

When I got three of those devices from a neighbor because they had as a family upgraded all of their kids' tablets, they were all very slow. Horrifically slow. After a factory reset they couldn't even upgrade from the stock 4.4 to 5.x because the famous 'no space' error message aborted the download.

I've been running the latest test build linked in this thread (20171122_224807) for a few days now and it runs fine on all three devices. Aside from the known MTP host message that pops up and the lack of Widevine DRM support due to the outdated kernel, everything works a lot better than I expected. Thanks for all you've been doing to make these older tablets into something useful again!

I'll probably start using them as a Spotify player coupled with a Bluetooth speaker, as a remote for my older Panasonic TV and the third as a backup to my Xperia Z4.
[Nexus 7 Android Development] birdturbo:
My bad guys, wrong thread lol
[Nexus 7 Android Development] dark0shark:

[Nexus 7 Android Development] Flounderist:
Thanks to [MENTION=2188693]AndDiSa[/MENTION], I was able to build and then successfully boot a custom kernel for Grouper.

It has been a building exercise only, so it is basically a copy of the excellent one provided in OP.

I'd like to add some features like CPU and GPU overclock, kexec support.

Do you think that building from some old sources (franco, metallice, motley) would give me a bootable zImage?

Afaik even LP releases had 3.1.10 kernel, so I assume it would boot.

Sorry for looking silly, but I am in the process of learning.

Any suggestion will be highly appreciated.
[Nexus 7 Android Development] chnapsy:
Thanks for this amazing job, thanks a lot ! my grouper run as new.

I just have a few issues :

-It's really hard to slide to unlock, I had often to do I't 2/3 times in order to unlock, where does that comes from ? Is it fixable ?

-Second and much more annoying problem, I cannotg get the sound going through the jack plug, is It a known issue ?

-Is there a way to change the size of the partition used for internal storage? It's very small and I'm already struggling with updates.

Thanks

C.
[Nexus 7 Android Development] MrHaroldA:
A kernel version higher than 3.8 will be greatly appreciated, as that will fix Magisk and thus Netflix!

Which version did you flash?
[Nexus 7 Android Development] Flounderist:
Typo: I was intending 3.1.10 :p
[Nexus 7 Android Development] chnapsy:
I took the first one on the download page, thinking It was the more recent, I suddenly feel a bit dumb realizing I didn't even check the build date ...

I flashed cm-14.1-20161130-UNOFFICIAL-grouper.zip

So I guess I better should try the latest ...
[Nexus 7 Android Development] chnapsy:
Just installed lineage-14.1-20171122_224807-UNOFFICIAL-aaopt-grouper.zip

Solved the issue with the lock screen :)

Still have the issue of no sound through jack plug :/ is It a know issue or should I start thinking about changing my USB/Jack flex ?

Thanks.
[Nexus 7 Android Development] aaopt:
I have a few groupers in use by my kids. The only one complaining about the audio jack not working is the one whose flex cable I most recently replaced to try to fix charging. Charging does work better now though.

Had you tried the audio jack before installing the ROM?
[Nexus 7 Android Development] pieceofphil:
little suggestion regarding the download link. Maybe you should rather use this link which directs to the Nexus 7grouper folder and sorts the builds that newest is the first.

Thanks for the ROM it's great.
[Nexus 7 Android Development] JustSomeDev:
I have used LOS 14.1 on Grouper for a few days now and have found no errors.
[Nexus 7 Android Development] chnapsy:
I actually just changed the flex with a new one as the usb connector was half dead, I'll try to roll back on the previous one where jack was ok.

I was just asking to know if It was a known issue with this rom or if It worse opening back the device to troubleshoot that at a ISO Thanks for your answer anyway, I keep you in touch ...
[Nexus 7 Android Development] Dggrr:
That may be hardware rather than the rom, it is a known problem with the device.

There is a little mini-board with the USB and audio jack. I had to replace mine a couple of years ago when the audio went on one side.
[Nexus 7 Android Development] fsw_informatrix:
@ chnapsy : just checked It, no troubles at all with the audio jack here.

Hi all,

I compiled my first Kernel for Grouper using AndDiSa kernel tree.

It has been compiled without tweakings from original source using a Google Toolchain arm-eabi-4.8.

I tested it on my device and it looks like the tablet improved a little, so feel free to flash it as a boot.img from TWRP.

Credits are going to [MENTION=3729448]aaopt[/MENTION] for the stock boot, [MENTION=2188693]AndDiSa[/MENTION] for source and [MENTION=4544860]osm0sis[/MENTION] for the img kitchen.

My Files App shows no files. It displays "Can't load content at the moment" when I select "Documents". I installed Astro File Manager. It has the same problem. It shows no files on my Nexus 7. However, I can browse my network Workgroup and see all the computers, and files on the computers. Also, when I start the Files App, I get the dreaded "MTP Host has stoppped" error, although I do not get it when I start Astro.

It seems like some kind of permissions problem.

I'm running lineage-14.1-20170717-UNOFFICIAL-aaopt-grouper.zip on rooted Nexus 7

I would appreciate any suggestions?
[Nexus 7 Android Development] Astra7525:

Thanks!

[Nexus 7 Android Development] Astra7525:
Installed your kernel. It works. Cannot report on any improvements yet, but will report if weird things pop up.

Want me to test something in particular?
[Nexus 7 Android Development] Flounderist:
Thank you for your feedback :)

I just compiled a new one based on [MENTION=4948627]daniel_hk[/MENTION] kernel tree.

It has CPU OC enabled and undervolting. GPU information are not shown on Kernel Adiutor and no thermal info as well.

I assume fstab might be the culprit, I could try repacking boot.img using RR fstab.

It is also missing DT2W, but I think it is a ROM defect.

Tweak some parameters on Kernel adiutor as follows for better performance:

Scheduler I/O: deadline

CPU Governor: Interactive

on interactive tweaks set:

go_maxspeed_load: 99

go_hispeed_load: 95

hispeed_frequncy: 1100000

I hope you enjoy it!

As usual credits are for [MENTION=4948627]daniel_hk[/MENTION] for kernel tree, [MENTION=3729448]aaopt[/MENTION] for LOS boot and [MENTION=4544860]osm0sis[/MENTION] for the img kitchen.:D

currently able to run older version of netflix that does not have the download feature. its version 4.16.1 build 200147

Netflix doesn't currently show up in the playstore. When i DLed the most recent apk online it says incompatible with device.

really just want to be able to get the download feature as i use it for my kids entertainment for the car

thanks for any help

I'm sorry the others here were right, you can't have the download mode without a newer kernel (which is impossible until now for our old device) I seem to gotten mistaken by my other device I got at home.

[Nexus 7 Android Development] nildex:
I researched and skimmed through this thread but wasn't able to find a build for Tilapia. Am I missing it from somewhere? Unfortunately the installation with grouper in the recovery simply aborts.

---------- Post added at 09:39 PM ---------- Previous post was at 09:31 PM ----------

Did you get around the MTP bug? By the way, I'm still looking for a Tilapia build, or for any possible way to flash it. ATM I only own a grouper build.
[Nexus 7 Android Development] hackintosh5:
To flash this on tipalia, you have to modify zip/META-INF/com/google/android/updater-script, changing all references of grouper to tilapia.

Note it may not work!
[Nexus 7 Android Development] nildex:
But it actually did, the installation at least. It has been running for less than a hour, so I cannot give guarantees on stability. To let the installation work I modified the updater-script file substituting all the grouper occurrences with tilapia and then instructed the tablet recovery to not check the zip signature.

It seems to be working well but admittedly not very smooth. There are no real lags but rather little fluidity in scrolling the interface. A little bug I had was the screen apparently turning off, and no pressing the power button or any other button could turn it on again. I solved this by disabling the adapting brightness setting, which supposedly was the cause, although I'm not sure.

Thank you for the help ;).

Hi,

I was able to successfully flash the ROM ... but i have no luck with the gapps ... i have downloaded the latest pico version as per the OP and tried flashing, on reboot i am unable to boot into the OS ... stuck with setup crashing endlessly ... the only way to get out of it is wipe /system and reflash the ROM ... i tried placing the confi text file in the same path as the gapps zip ... no luck !!!

Help to successfully flash gapps is appreciated.
[Nexus 7 Android Development] hackintosh5:
Please, boot to system without gapps, authorise adb. Install gapps. Boot. Check output of adb devices while device boots. Tell if los load logo jumps, google logo shows, all is important! One last thing:ensure zip sig verify in on in recovery.

[Nexus 7 Android Development] aiamuzz:
Hi, so one can't install the ROM zip and the gapps zip back to back ... as we could back in CM days ?

by 'authorize adb' ... do you mean i need to enable ADB debugging and authorize RSA fingerprinting ?

and by 'install gapps' ... do you mean install it via booting into recovery ... flash gapps zip file ?

i guess this is my first attempt at lineage OS ... just trying to understand if a certain vocabulary (methods) has changed since CM days ...

thanks.
[Nexus 7 Android Development] aiamuzz:
ok ... i followed the steps you suggested ... i am using CWM non-touch version ... i flashed LiOS zip ... booted into the OS ... enabled and authorised adb ... rebooted into the recovey ... flashed gapps ... booted ...

google log shows while booting.

LiOS logo shows up too

LiOS boots to my lockscreen.

I unlock the lock screen ... i am greeted with ...

Setup Wizard keeps stopping

Close app

mute until device restarts.

so no OS to setup my device.
[Nexus 7 Android Development] hackintosh5:
I suggest that you aren't wiping data cache dalvik as per the instructions. Use twrp and swipe for factory reset under "wipe"tab. Also ensure to wipe system.
