Dirty flash 0106 over prev version w/Pico version of test open gapps (thx ipdev). All seems to be working well.

Also seems to resolve the gMaps issue without editing the permissions system file mentioned a few pages back.

Thanks OP & contributors!
[Nexus 7 (2013) Android Development] s9amme:
Saw the update today and decided to give Android 11 a spin. Used the pico version of the test open gapps from ipdev and also flashed magisk beta 21.2. Everything installed with out issues. Thanks for getting Android 11 on this device. I never thought I'd see anything past Nougaut on this device and now here we are!
[Nexus 7 (2013) Android Development] ipdev:
That does not seem right. :confused:

Are you on Flo or Deb ?

BitGApps R19 installed size should be about 128.6M, so it should still fit.

If you are only showing 157M free after installing l18.1

Either your device was only partitioned to a 1.1G system or the resize script is not working for your device.

What recovery are you using?

Unofficial Flo/Deb are built on a 1.1G system partition.

See this post (and the one above it) for note on current build size.

[ROM][UNOFFICIAL][10] LineageOS 17.1 [deb][flo] xda thread - Post 605 - Link

When the rom is installed, a script runs to resized the image to fill the whole system partition.

This allows them to work on any partition size above 1.1G.

Installed l18.1 (flo) actually only uses 973.2M of system the rest is free usable space.

Installed l18.1 (deb) actually only uses 988.5M of system the rest is free usable space.

Cheers. :cowboy:

I was able to install successfully after I repartitioned again. Thanks. One question though, Can I replace the LO camera with the GCam that will work on 18.1?
[Nexus 7 (2013) Android Development] Enry44:
I tried your gapps work very well. Thanks
[Nexus 7 (2013) Android Development] pat.seven:
Hi guys sorry for the trouble but I need to request a couple of apks for this ROM as I haven't found any of them that will work as of now. If there are those here that tested and installed the following without any trouble, can I request for the apk of these:

- Google Camer

- Android Auto

Thanks!
[Nexus 7 (2013) Android Development] ipdev:
Happy to see you got it installed.

Welcome to Android 11. 🙃

--

Doubt Google camera will work as is, and older version may still work ?

Give it a test and let us know. :)

Generally you do not need to remove LOS/stock camera to test other camera apps.

The default LOS camera works.

- Record and save a video.

- Save a picture.

Just did a quick test with Open Camera and Snap Camera HDR.

- Both can record and save a video.

- Both can NOT save a picture.

¯\_(ツ)_/¯

Open Camera PlayStore - Link

Snap Camera HDR PlayStore - Link

Snap Camera HDR Trial PlayStore - Link

Note:

Currently I have an odd setup.

I am testing different options for installing and removing using an OpenGApps config script.

So it could be something I removed or added in my last install affecting something.

OpenGApps Wiki GitHub - Advanced Features and Options - Link

--

If you want to test gCam, you may need to use a gcam mod version.

It has been awhile (year/year and a half) since I used one (Pocophone F1) but, I think Arnova's was the one?

This site has most of them, take a quick look at the Dev/Mod page for main differences between their builds.

Some have xda threads, some have TG channels, some have none or other.

Hi,

I have tested your " OpenGApps UNOFFICIAL_TEST MediaFire - Link " and for me Google Location doesn't work (waze & maps): do you have the same issue ?

(I use this rom, on PI4: lineage-18.1-20210104-UNOFFICIAL-KonstaKANG-rpi4.img)

Thank you
[Nexus 7 (2013) Android Development] ipdev:
Location is working fine for me.

As for Google Maps and YouTube, seems to only work correctly if you install from PlayStore.

Bit OT for this thread.

Open, Bit, Nik, Other(s) GApps, all seem to have the same/similar issue.

Cheers. :cowboy:
[Nexus 7 (2013) Android Development] myspac:
In fact, with gapp from Bitgapps (and activate all in location settings, Wif/BT ), same problems:

- Waze: impossible to show the map and to localize me

- Google Map GO (browser): map ok, travel from one position to second Ok, but, "my position" to another: impossible

- MAPs: map ok, travel from one position to second Ok, but, "my position" to another: impossible

All apps was installed with playstore.

Dirty flashed Jan update over Dec lineage ROM installed google apps from the links on the front page of this forum
[Nexus 7 (2013) Android Development] neilth:
Yesterday on a Deb version Nexus 7 I unlocked the bootloader, installed TWRP, did a factory reset & formatted /system and then ran the sysrepart script. I then installed LOS 18.1, Gapps pico and Magisk 21.1, rebooting to recovery after installing each software component. The system then booted up fine into LOS and I completed the installation of the Magisk Manager.

I have no experience with Magisk and I see several security issues with the system as it’s configured. I am notified after boot up by System Security that the build was signed with public keys and that SELinux is not enforcing. If I check SafetyNet in Magisk Manager I get an Attestation failed response saying basic integrity -, ctsProfile- and evalType BASIC. In addition, in the Play Store app, Play Protect certification says Device is not certified.

How can I resolve these security issues with my LOS 18.1 installation which, other than these issues, appears to be working perfectly so far? I just saw in the Magisk Manager a file available called MagiskHide Props Config. Will installing this file in the app allow me to configure Magisk to eliminate the security issues I am seeing?

Thanks for any help and assistance with these issues.
[Nexus 7 (2013) Android Development] ipdev:
Currently SELinux is Permissive.

The builds are test-keys.

SELinux is generally the last to fix (time consuming) once everything is working.

The builds are very stable but, still in testing.

Both are not a big problem when it comes to custom roms.

Especially on an older device being brought up to current Android.

Actually I am surprised Lineage Trust does not warn about adb insecure.

Magisk will block/hinder adb insecure by the way.

--

As for passing SafetyNet.

In MagiskManager, under settings, enable MagiskHide.

This will hide the sensitive props that SafetyNet looks for.

As for the LineageOS Trust SELinux and build signature notification.

You can disable in Trust.

Settings-> Privacy-> Trust. (Toggle off SELinux status and Build signature.)

For PlayStore.

Long press the icon.

Select the i in the circle-> Storage & cache-> Clear cache and Clear storage.

Note:

You may only have to clear cache. When you clear storage you will also clear updates to PlayStore.

May take a reboot or a little time for Play Certification to show at all.

Cheers. :cowboy:

Hi all

From now on, I want to thank all of you who keep this hard work for our nexus 7.

I want to congratulate you, because I love this version that I didn't even know existed (I'm outdated) ...

So far the nexus 7 seems to be fast and fluid with the latest version of android!

I want to ask, and I apologize in advance for talking about another topic that has nothing to do with you, but here's the thing. I use my nexus 7 in the car, with music, gps, and reverse camera. However I was using the stock version 6.0.1 android with the kernel "Timur's Kernel v4.0" (I don't know if you know) ... And as I have now discovered this version of your android 11 and how fast it is responding was there even a way to install this kernel on this ROM?

Thank you very much
[Nexus 7 (2013) Android Development] neilth:
Thank you very much for your guidance, All security warnings are now gone, SafetyNet and the Play Store are certified and happy.

I had forgotten to include that I also installed the flo-deb-followmsi-kernel-eleven-20201130-AK3.zip in my original request for assistance. I am experiencing some performance lag and poor battery life. Overnight my Nexus 7 battery loses 7% while asleep and when in use during the day, it drops like a rock. Is there an app available for tweaking the kernel parameters which may remedy these two problems?
[Nexus 7 (2013) Android Development] lollyjay:
Wow I wish my N7 had ONLY 7% loss overnight. 😢
[Nexus 7 (2013) Android Development] neilth:
I haven’t used a Nexus 7 for awhile before getting and working on the one I’m using now, but I don’t remember battery life being a problem. I’m pretty sure that typical overnight battery loss was 2 to 3% the last time I was using an LTE Nexus 7 in 2018. I’m going to post a general question about using alternative kernels with this Android build to improve battery life and responsiveness. Hopefully, some folks have tried this as a remedy.
[Nexus 7 (2013) Android Development] neilth:
When using a different kernel, such as the flo-deb-followmsi-kernel-eleven-20201130-AK3 version, what possible enhancements does this add to our Nexus 7s? What app is best to interface with the kernel allowing customization of its features? My Nexus 7 with LOS 18.1 needs its battery life per charge and responsive improved. I’m hoping for some advice on the possibility of achieving some of this via available kernel tweaks.
[Nexus 7 (2013) Android Development] names:
I'm new to the Nexus 7 device and flashed this ROM as soon as I saw it. I have to say, everything works great and a device as old as the Nexus 7, which I am very pleasantly surprised.

The only issue I am experiencing is the display turning itself on randomly over and over again. Apologies if this was already addressed, but is anyone else encountering such an issue?
[Nexus 7 (2013) Android Development] taadow1030:
Naptime on the Play store by Francisco Franco is very good for ensuring app hibernation.
[Nexus 7 (2013) Android Development] neilth:
Thanks, but I’ve already installed the EX Kernel Manager app and I’m trying to learn about all of its settings and features. The one thing I’ve learned is that there’s a lack of documentation available for kernel managers. I’ve been browsing relevant XDA forums and I have found some useful info.
[Nexus 7 (2013) Android Development] SGH-i200:
You can't use a kernel for Android 6.0.1 on Android 11! :-(

You need a Android 11 compatible kernel which has support for "USB Host Mode Charging". If there is none, find a kernel developer who is willing to include this feature in his kernel!
[Nexus 7 (2013) Android Development] n3kf:
Took the plunge and installed the 01/06 version, the test nano gapps, and magisk on one of my Flo's today. Working very well. @followmsi thank you thank you for all your work. Fantastic job. It seems like memory is being managed a bit better with this then with 17.1. Like it so far and probably just going to get better.
[Nexus 7 (2013) Android Development] n3kf:
I'd like to play with MicroG on one of my 16gb Flo's. It's anyone using it and care to list what you did to get it working. Just a quick overview. Thanks.

Guess I'm stupid but with the new forums both in the app and on the web I can't figure out how to search an individual forum!!

Update: it works OK. Finding I have too many tie ins to play services. So went back to GApps.
[Nexus 7 (2013) Android Development] danu1012:

Media storage keeps stopping error message.

Is there a solution?

Thanks
[Nexus 7 (2013) Android Development] n3kf:
This definitely works pretty good. For me, I find that noop works better as an IO Governor. Also find that by limiting background tasks to 3 (no scientific reason for 3), that responsiveness is better. I haven't seen any bad effects yet by doing that. As usual everyone's workload is different. So YMMV.

[Nexus 7 (2013) Android Development] neilth:
You bring up a good point about making changes to the kernel settings.

Using the EX Kernel Manager on my Nexus 7, there are tons of settings, but very little background information available as guidance. I found one great guide here on XDA, https://xdaforums.com/t/ref-guide-m...pu-governors-i-o-schedulers-and-more.3048957/ but it only covers several items, such as CPU governors, I/O schedulers &TCP algorithms. There are so many additional settings available in the app for the kernel which will possibly improve system responsiveness and battery life, such as the memory settings. How should ZRAM, KSM, Low Memory Killer & the virtual memory options be configured? What is parrotMod for the touchscreen? How is the optimal setting for apply on boot delay determined?

I see that CPU voltage adjustments are available for up to 2214 MHz in the app, but there is no apparent way to actually raise the CPU clock above 1512 MHz.
[Nexus 7 (2013) Android Development] johndaog:
I am having touchscreen issues, so i am hoping Parrotmod will help me
[Nexus 7 (2013) Android Development] ddonmez:
Parrotmod works like a charm. It sends parameters for cut connection of rotation. Give a try...

Firstly, I want to thank the dev for all of his work on this ROM as it is very fluid and seemingly one of the best third-party ROMs I have used.

Secondly, forgive me as I posted this in Lineage 17.1 Flox thread without much luck.

After running on Lineage 17.1 Flox and then this build of Lineage 18.1 for a couple of weeks (back on 18.1), I am trying to get back to stock and am looking for any assistance in doing so.

When I've tried, I end up going into a bootloop, but can get into fastboot and back to this ROM without issue.

I have tried repartitioning back to stock with the same results.

The main reason I'm trying to get back to stock is for a car install.

All help is appreciated.

Thanks

Using Clamor's reparation script, will create an extra partition.

vendor is created at 30 and userdata becomes 31.

Not sure if that is giving you an issue.

Did you try manually installing the last flo factory image?

Clamor''s repartition script is indeed what I have used for modify and stock. Both complete without issue so it must be what you referenced.

Hi and thanks again for the ROM!

I just installed lineage-18.1-20210207-UNOFFICIAL-deb and found that my device now connects to my router in WPA2/WPA3 mode - great work!

However, I was not able to install open_gapps-arm-11.0-pico-20210130-UNOFFICIAL_TEST due to the error 70 (not enough space in system partition).

I did a clean install and even flashed the sysrepart_1280_120.zip again but still no luck.

I could install BiTGApps-arm-11.0.0-R19_signed.zip but I´m having the already known issues with GPS and Google Maps (installed from Playsore) crashing constantly a few seconds after starting it.
