Really I tried a dozen versions going back 8 years. I hope you are right, looking forward to test it.

I also get stuck at 'checking for updates' when doing clean install after connecting to wifi. I can force it to pass (do not use any network to setup) but it means I have to create a user account and the add another account once in, not ideal.

Waze 4.34.1 works, I am shocked, I am sure I tried this version before after doing a search on this issue and map was black, as was a lot of other versions.

Perhaps it is because I just started fresh...but this is probably the tenth time i installed the rom....weird but good. :)
[Nexus 7 Android Development] alphalvr:
Is it common knowledge what versions of 'Tom Tom' and 'Sygic' navigation programs work?

I tried the latest and Tom Tom keeps stopping as it starts up and Sygic seems to have trouble loading the map...it tries but runs out of steam.

Still a great rom, just trying to find the best Navigation program to use.
[Nexus 7 Android Development] :
@alphalvr I use both Sygic (18.8.6) and Here maps on my microg grouper using the latest ROM. Sygic always plays up after dirty flashing a ROM update and I have to reinstall it to get it working again.

Have you got rhe location permission enabled in Sygic and location enabled in android settings? Sygic will hang if not as it requests location on opening. Also, if you're using microg then you'll need some 'location service' files too, and enabled in microg settings.
[Nexus 7 Android Development] Portgas D. Ace:
For navigation purpose, I think Magic Earth is also worth a shot, though it might not be as accurate as Google Maps when it comes to closed roads or traffic every now and then. Magic Earth offers online as well as offline navigation, based on OpenStreetMaps and is available from the Play Store. Works well for me on both my Grouper with microG as well as my Pixel 3 with microG.
[Nexus 7 Android Development] alphalvr:
you said both, Tomttom and Sygic, any special tips for Tomtom?

I originally used the MicroG version but when I couldn't get waze to start I swapped to the other version and Pico gapps.

I was trying newer versions of Sygic 20.8.... I will try the one you are using. The new one lookis like it is working but the map has no features, it is just black and grey. After 5 mins my road name appears at the bottom of the screen like it is slowly loading but I waited hours and map never finishes loading.

Tomtom 3.2.12 just will not start, it tries then stops.

In my frustration I ordered a newer tablet from Acer (no research) then realised it couldnt be rooted so no good to me, I need root at very minimum. :)

My only issue is with nexus is it occasionally seems to hang which would be annoying for in car use, but could just be because I am using versions of apps it does not like.

I will try the other nav programs suggested.
[Nexus 7 Android Development] Portgas D. Ace:
I haven't tried TomTom or Sygic, so I can't comment on them. I am very pleased with Magic Earth, as it runs as intended, so I don't bother with other apps that needs some degree of tinkering to get it working.
[Nexus 7 Android Development] Lumbis:
Location services does not work for my Nexus 7 (2012). I installed the mg version, then F-droid and Aurora play store. Locations accuracy is set to high (wifi + bluetooth + GPS) but no signal in Maps or GPS apps. The apps have location permission. =\
[Nexus 7 Android Development] Portgas D. Ace:
Let's try to solve this issue:

1. Ensure that microG is set up correctly for location purpose. Open microG settings and run the included self check. All checkmarks should be enabled, so that microG is able to handle the location backends.

2. Ensure that location providers are set up correctly. Open microG, check the location modules section. All of them (Deja Vu as well as Nominatim) should be enabled. You can add additional location providers, e.g. GSM Location Provider or Mozilla Location Services, both available from F-Droid.
[Nexus 7 Android Development] Lumbis:
Thanks for the reply,

Where do I open the MG settings? I do not see it anywhere. I even reinstalled everything just to make sure I got the correct zip.

I booted to TWRP 3.5.2.9, wiped everything, installed only aosp_grouper-7.1.2-mg-ota-20210917.eng.ds.zip, booted into OS. I cant see any MG app anywhere.

Looked at some screenshots now and my settings icon is just named "Settings". Looks like MG is not installed at all. Something wrong with the source ZIP? The MD5 matches...
[Nexus 7 Android Development] Portgas D. Ace:
That's the correct zip file (though the one with September security patch level instead of the October one, see https://xdaforums.com/t/rom-nzh54d-...droid-7-x-aosp.3467514/page-243#post-85742861 for newer version).

Your issue here is that microG isn't installed automatically by flashing the ROM zip, you have to manually install the corresponding microG core apps (Service Core, Service Framework Proxy, DroidGuard Helper). Check https://microg.org/download.html for instructions and then report back. I would advice to use F-Droid for installation, so you can update those apps afterwards in an easy way. Proper way to do so: install F-Droid, then open the above provided link for microG repository on your tablet's browser and click on the QR code. This should add the given repository to your F-Droid sources.
[Nexus 7 Android Development] Lumbis:
Oh, but what is the point then of the mg zip version?
[Nexus 7 Android Development] AndDiSa:
You need to prepare the ROM in a specific way so that MicroG can be installed and is working.
[Nexus 7 Android Development] Portgas D. Ace:
What AndDiSa said above. The ROM needs some signature spoofing patches, so that microG is recognized as Google Play Services. You can either use the microG patcher to patch the "regular" ROM (without microG patches includes) or use the microG version, where those patches are already applied. For me, it is a no-brainer regarding the question which ROM version to use.
[Nexus 7 Android Development] momentoid:
I was away from my Nexus 7 2012, and thus late to the party. But, successfully installed the October 2021 Grouper ROM and Oct 21 version of GApps. Everything works great. Thanks, @AndDiSa.
[Nexus 7 Android Development] tomtom_38:
Hello,

is android 7 with security patches save as android 11 with the same security level/ date?

how long is the security patch support for android 7?
[Nexus 7 Android Development] AndDiSa:
@tomtom_38 officially there are no security patches for Android 7 since about 4 years ago. The security patches applied here are backported from newer Android versions.
[Nexus 7 Android Development] FLONE:
I tried to update and I can't install Gapps, insufficient space.

OTA-Package installed without errors. I have updated in the past and I did not have this error.

I have attched the log. Can you guide me how to solve it?

Thank you in advance!
[Nexus 7 Android Development] AndDiSa:
@FLONE you didn't use the gapps-config-....txt files mentioned in post #2, did you?
[Nexus 7 Android Development] FLONE:
The last time I updated it didn't involve this step. Sorry I didn't document myself enough.

It's okay now, thanks.
[Nexus 7 Android Development] phoenix_wnd:
Thanks for your hard work, I made a build from your sources myself.

I had to comment out a line in the file:

/device/asus/grouper/sepolicy/system_server.te:

# allow system_server su:process ptrace;

else build woudln't proceed.

Although I had to manually edit:

/.repo/manifests/default.xml:

<project path="system/netd" name="system_netd" remote="ads" revision="ads-7.1.0" groups="pdk"/>

to:

<project path="system/netd" name="system_netd" remote="ads" revision="ads-7.1.2" groups="pdk"/>

Nevertheless, build was successfull at the end and my device runs like a a charm again. :)

Big *thumbs up*
[Nexus 7 Android Development] shyguy22:
I installed the version for grouper with micro-g patches shortly after your announcement. I use my nexus occasionally for YouTube(Newpipe)/SS/general surfing and got no bugs or problems.

Thank you very much for your efforts to keep these old tablets useable, BTW!

Additionally, I have a question: Is there any chance you could enable us to toggle "immersive mode" on permanently. I couldn't get these temporary workarounds running and as is understood it they wouldn't survive a reboot.
[Nexus 7 Android Development] AndDiSa:
@phoenix_wnd thank you very much for reporting the issue. I just pushed a corrected version of the manifest.

Regarding the issue with the sepolicy I cannot reproduce on my side ... it's compiling without any issues, even a clean build 🤔
[Nexus 7 Android Development] AndDiSa:
New Versions 7.1.2 (2021-11) are available

Hi guys, a new release but only a few changes, i.e. the security paches for November 2021.

The full list of changes, as always, you can find in my Github repos

The "standard" versions for Grouper / Tilapia are available for download:

aosp_grouper-7.1.2-ota-20211105.eng.ds.zip (MD5: d8dfedbca14005dce954931d1953e80a)

aosp_tilapia-7.1.2-ota-20211105.eng.ds.zip (MD5: b5d1f12db835d236c0b736da3bcd79ed)

as well as the MicroG-Patched images:

aosp_grouper-7.1.2-mg-ota-20211105.eng.ds.zip (MD5: 4c0ef1ec4507940dda406d4fe83965b0)

aosp_tilapia-7.1.2-mg-ota-20211105.eng.ds.zip (MD5: cb7d4c64a4c9d48b901f92027abc7c2e)

I quickly tested the ROM and didn't find issues, nevertheless I will wait for feedback from the community before I'll add the new version to the OP.

If you report a successful (or unsuccessful :)) installation, please note which version (Grouper / Tilapia, with or without MicroG-patch) you have installed and tested. Thank you very much!

Stay safe!
[Nexus 7 Android Development] :
Grouper MicroG installed and working. (y)

Dirty flashed and re-rooted.
[Nexus 7 Android Development] momentoid:
Dirty flashed Grouper ROM 2021-11 version and GApps Nov 5, 2021 version. Tested my regular apps. Everything is good.👍

Kindle app needed remove/reinstall, that's because I have not clean flashed since the big changes a couple of versions ago. Maybe I will do a clean flash on the next update.
[Nexus 7 Android Development] GullRaDriel:
Installed on my grouper and currently waiting for the arts to build.

Thanks for the hard work @AndDiSa :-)
[Nexus 7 Android Development] ev-olution_net:
Did someone tried to send or receive SMS messages using this ROM (tilapia)?

I tried few different apps, non of them sending SMS anymore. It's like SMS functionality is disabled in this ROM.
[Nexus 7 Android Development] MaNFr3:
Hi,

succesfully installed "aosp_grouper-7.1.2-mg-ota-20211006.eng.ds" but gapps gave me the E70. So I booted to system (no gapps = no wizard = no anithing but it booted up), via adb i've pushed the txt file.

Back to recovery i've adb sideloaded gapps, since then I'm stuck with bootloop on android logo.

Tryed 2 times the process with the same results.

Anyone could suggest something?

Thanks!
[Nexus 7 Android Development] AndDiSa:
@MaNFr3 did you try to reflash the ROM and then installing GApps? In addition I suggest you to clean Dalvik cache.

Then, depending on the number of apps you have installed, initial boot may take some time.

Edit: I just saw you flashed the mg-version and you are trying to flash GApps. The mg-version is intended to be used with the MicroG version of the GApps, not with the Google version.
[Nexus 7 Android Development] marty_bebop:
Grouper: Nov mg ROM, Magisk 23, Aurora Store

All good. Many thanks.
[Nexus 7 Android Development] jwhite5840:
I am running the 2021-10 build of the "standard" version of this ROM on my grouper. I did a full wipe and clean install, followed the instructions to use the pico Gapps with the pared down list. Unfortunately I am getting constant issues resuming from deep sleep. When I am using the tablet it has no problem and is nice and snappy. But if I let it sit for more than 30 minutes it will not wake up and I have to hard power cycle it. I have rewiped and reflashed a couple times but have the same result. I thought about trying it without Gapps but I need this functionality. I am coming from a 7.1 build of Resurrection Remix where I did not have this issue at all; just wanted the newer security patches. Any suggestions?
[Nexus 7 Android Development] AndDiSa:
@jwhite5840 hmm ... as I did not check this recently I can neither confirm nor deny that issue. Did you try already the versions from September and/or August? Can you reproduce that issue there, too?

I'll do some tests on my side and try to identify the culprit.

Thank you for reporting the issue!
[Nexus 7 Android Development] jwhite5840:
I tested with both September and November versions and had the same results. I suspect that it may be an issue with the 3.5.2-9 version of TWRP so I am going to revert to 3.2.1-0 and see what happens,
[Nexus 7 Android Development] AndDiSa:
@jwhite5840 I doubt that TWRP is the reason for the issue. It's more related to min-frequency of the CPU when in sleeping mode ...
[Nexus 7 Android Development] jwhite5840:
Turns out my /data partition has issues. At first it was just occasional write errors, but after attempting to use Wug NRT to flash back to stock with the "soft-bricked" option it got a lot worse. Now /data cannot be mounted and shows 0 byte size in TWRP. Attempts to "fastboot erase data" or "fastboot format data ext4" fail and cause the bootloader to hang. I get error 8 when I attempt to repair the filesystem. Currently have flashed /recovery back to TWRP 3.5.2-9 with /cache and /boot on stock 5.1.1 so that I can at least charge the battery. Have been searching other threads to see if I can find a solution to the problem, but clearly it was going bad before I tried to flash this ROM and it was probably only a matter of time before I hit a catastrophic failure.
[Nexus 7 Android Development] AndDiSa:
@jwhite5840 I did some tests with my device and I cannot reproduce your issue. I let it on my desk for more than eight hours but it woke up without any issues. Sorry to say but it looks to me as if your issue is really related to your device itself. Hopefully you are able to resolve ...
[Nexus 7 Android Development] Luckz27:
Hello, I tried again and again to install the "standard" Grouper version but when I tried to install GApps (pico) I always got the Error 70 and no fix worked! What can I do, please?

P.S. No problem with the MicroG's one.
[Nexus 7 Android Development] AndDiSa:
You didn't read post #2 of this thread, do you?
[Nexus 7 Android Development] Luckz27:
No, I did read it and I searched for some other solutions online too but nothing worked! I can't understand what I do wrong! 🙈
[Nexus 7 Android Development] AndDiSa:
@Luckz27 where did you store the gapps-config-grouper.txt ?

Probably you will need to re-flash the ROM, too, to clean up the /system partition.
[Nexus 7 Android Development] Luckz27:
In the zip file itself of the GApps.
[Nexus 7 Android Development] AndDiSa:
@Luckz27 you need to store it as it is on /sdcard no need to modify the zip. During the installation the installer checks different directories for those gapps-config-* files.
[Nexus 7 Android Development] Luckz27:
I understood... And how I can do this? I don't know how to do it from recovery.
[Nexus 7 Android Development] AndDiSa:
@Luckz27 ??? I do not understand your problem. TWRP recovery has also a file manager which you can use to copy / move files around. Copy the gapps-config-grouper.txt into the /sdcard/ directory. Then flash aosp-grouper-... ROM and GApps Pico and everything should run through without any problems.
[Nexus 7 Android Development] Luckz27:
Don't worry, I think I find what I needed online! Since I flash the ROM and GApps by sideloading them, I didn't know I can use the recovery to mount the device and transfer files from my PC too.

I will inform You in the next days!
[Nexus 7 Android Development] Luckz27:
Okay, I successfully flashed ROM and GApps_Pico but now I can't install any apps from GPlay Store. 😂🙈
[Nexus 7 Android Development] ev-olution_net:
Unfortunately this ROM has problems with Nexus 7 3G device. First of all it never connects to 3G network, only 2G, even when it's set to "preferred network type: 3G" in settings. If I try to go to setting and do manual scan of cellular networks I get error message telling there was an error while scanning for networks. I tried many different locations, exactly same result. Also there is notification always popping up saying "Bug report #1 captured". And the last thing, after updating my Nexus with this ROM I am unable to send or receive sms messages anymore. I really like how it works on my other WiFi device, but for 3G I guess I will have to look for something else or revert it to stock ROM.

EDIT: It was pointed out to me that there is no 3G networks anymore in Germany and this is why my Nexus 7 does not connect to 3G anymore. Sorry, my mistake ;)
[Nexus 7 Android Development] AndDiSa:
@ev-olution_net probably you can provide with some logcat from the issue? It's difficult to analyze without any information. Probably it's only a matter of permission settings ... 🤷‍♂️
[Nexus 7 Android Development] ev-olution_net:
What exactly I should look for in my logcat? Errors? This is a logcat of errors while I tried to scan for cellular networks and error message was returned. Although I can't see any related error in logcat file.

logcat
[Nexus 7 Android Development] ev-olution_net:
With SMS something weird is happening. I just checked my summary of SIM usage, and I actually see it logged with my provider. Even phone number shown in summary matches the one I am trying to send SMS to. I tried sending it with country code and without it. Both appears in my usage summary. But they never reach the recipient. Also non of SMS gets delivered to Nexus 7. That's very strange. I will try to call my mobile provider on Monday to see if that's not their issue.
[Nexus 7 Android Development] AndDiSa:
@ev-olution_net one additional question: in which country you are living? It came into my mind that in Germany all network operators have shut down their 3G networks (UMTS) in favour of 5G. So if 2G is working but 3G not it's probably due to the fact that there is no 3G available ...
[Nexus 7 Android Development] ev-olution_net:
Ups... My mistake. I do actually live in Germany and never heard of 3G switching off. Just checked if this is true:

"Telefónica Deutschland / O2 is accelerating the shutdown of its 3G network in various regions of Germany. Instead of the originally planned implementation by the end of the year, the company will now convert the majority of 3G sites as early as September and carry out the last large-scale shutdowns by mid-November."

I do use O2 and probably it was a coincidence that I updated ROM at the same time when O2 switched off 3G in my location. Funny thing they claim that they replacing 3G with 4G or 5G. Many German rural places has no GSM signal at all, and now they switching off the only available network. That also explains why GSM signal became so weak in my house recently

Thanks for pointing out the cause of no 3G connection. I will edit my previous comments.

I am still confused why SMS does not work anymore. But because I get charged for them, my guess it might be also O2 problem and not my Nexus 7.
[Nexus 7 Android Development] Luckz27:
Something is wrong... @AndDiSa
[Nexus 7 Android Development] AndDiSa:
@Luckz27 hmm... I have no idea, I never saw something like that. Looks to me as there is some kind of ghost touching ...
[Nexus 7 Android Development] Luckz27:
Thanks for the diagnosis of ghost touching! I fixed the problem in a very easy way and it was hardware!

Here is the fix instructions:

https://xdaforums.com/t/nexus-7-201...ing-issue-ghost-touches-hardware-fix.3101786/

But now I have a new problem: I CAN'T create a new folder or download files from the browser... What am I doing wrong now? 😂🙈
[Nexus 7 Android Development] AndDiSa:
@Luckz27 ... most likely file permissions are missing for the browser.
[Nexus 7 Android Development] Luckz27:
Okay, I got root permission. Now, how can I do this?

I can't even save a screenshot!

Here I'm simply trying to create a new folder:
[Nexus 7 Android Development] AndDiSa:
You don't need root permissions, you only need to give the browser file permissions, i.e. go to settings/apps/ and look for your browser application, e.g. Chrome. Then go to permissions and enable storage permissions (I suppose those are disabled).
[Nexus 7 Android Development] Luckz27:
All storage permissions for browser, file manager ecc. in Settings are enabled, so I don't think that is the problem.
[Nexus 7 Android Development] AndDiSa:
@Luckz27 did you check the Download Manager permissions, too?
[Nexus 7 Android Development] BagusPambudi:
very useful information, thank you, hopefully you will continue to provide more information
[Nexus 7 Android Development] Luckz27:
Of course! I'm a noob but not so noob! All needed permissions in Settings are enabled but that's not the problem. I think it is something like this but I don't understand what I have to do:

FIXED UP!! It was a file system error because mine was formatted in ext4.
[Nexus 7 Android Development] ev-olution_net:
I get similar results if I keep my fingers on a screen while my Nexus 7 powers up. If I don't touch screen while it is switching on, no issue afterwards. I know you sorted your issue by removing two pins inside tablet. But I found it's not necessary.
[Nexus 7 Android Development] momentoid:
Hey @AndDiSa, I noticed in Settings>Backup & Reset, the "Backup account" option is greyed out. Is this preconfigured in the build? I have a Grouper and use GApps. Thank you.
[Nexus 7 Android Development] AndDiSa:
@momentoid no, no special preconfiguration regarding settings ... but I just checked and it's the same on my device even if I was able to select to store backups on Google Drive ... :unsure:

Not sure whether it's related to the fact, that the device is also showing "not certified" ... probably Google is offering the backup only to certified devices ?!
[Nexus 7 Android Development] NikoNik7:
Hi,

How is the microG version installed? Just one file and all, or do I need extra steps? Like installing the AuroraStore?
[Nexus 7 Android Development] Portgas D. Ace:
Quite simple. Just flash the microG version provided in post #2. Then head over to the microG download section and install the corresponding apps from there. From my point of view it makes sense to install all provided apps beside Fake Store (you can install Aurora Store directly from F-Droid, for example). Reboot your device afterwards, then open microG Settings app and set it up. That's it.

EDIT: by adding the microG custom repo to your F-Droid sources, you can get automatic microG updates via F-Droid.
[Nexus 7 Android Development] NikoNik7:
Hi, you mean ...provided in post #1?

And how better head over to the microG download section and install the corresponding apps from there?

After installing the MicroG version, I can neither access the Internet (no app), nor install APK (although I have permission). The system does not see the APK at all.

In TWRP APKs are not installed either...
[Nexus 7 Android Development] Portgas D. Ace:
If you can't access the internet (or install apps from storage or adb), there is something wrong with your setup. Do a clean flash of the microG ROM version, then reboot the system and try again.
[Nexus 7 Android Development] username one:
Yes, "Downloads" shows no files. I had to install F-droid from the PC through ADB and then install apps from there.
[Nexus 7 Android Development] NikoNik7:
Yeah and I only got the adb install too.
