Working awesome ! thanks !

Minor thing is that it take like 8 ~ seconds to load settings menu.
[Nexus 7 Android Development] chinchulin01:
Hello all.

I clean flashed the 5/10/2019 build of this ROM onto my Tilapia but I can't see any phone icon and I can't neither make calls nor receive them. There's no txt messages icon either and that function is not working at all.

I can browse the Internet and use WhatsApp and other data dependant apps without problems using 3G.

Could anybody help me here?

Thanks in advance!

I just brought out of storage my nexus 7 2012 grouper. It is rooted (TWRP 3.xxxx installed and su).

It boots up fine but is still on android 4.4.2 with kernel 3.1.10-g4776c68

I would like to update it to a stable but more recent android. So my questions are:

1. Is it sufficient to just do the follwowing steps:

Update Installation

Boot into Recovery

Install 7.1.2 Grouper OTA-Package (Build 20191215) (md5: ea7d70833ec53fe23229bd639a2b9e37)

or

Install 7.1.2 Tilapia OTA-Package (Build 20191215) (md5: 03207b549ea5c0ed65915f3a300a8c94)

Reboot into recovery

Install Open GApps (arm/7.1/pico)

Wipe cache/dalvik-cache (optional, but suggested)

reboot

2. Will I lose root?

3. It was rooted with su. Do I need to move to Magisk?

I am updating to use with some more recent apps.

Thanks.
[Nexus 7 Android Development] Flounderist:
You could follow these steps:

- update the device to 5.1 firmware using fastboot for a clean start.

- install latest twrp 3.3.1

- install ROM and gapps

- reboot and complete setup

- flash Magisk to gain root access.

- profit

Move any file outside from device before upgrading to avoid any file loss.

If you can, use pico gapps build before 14/12.

:good:
[Nexus 7 Android Development] paasoares:
As far as i know, you can´t use this device (even the tilapia version) for making phone calls.

Tilapia version allows you to use 3G but no phone functionality.

cheers
[Nexus 7 Android Development] maybeme2:
Thanks for taking the time to reply.

May I ask why you suggest 5.1 rather than later? Unless 'firmware' is different than the android os. Is it?

Where do I download the grouper 5.1 firmware?

What fastboot command to install it?

Which ROM is available and works well? Android 6 to.9? I've used and liked lineageos on nexus 5, but looking through XDA, lineageos seems to have problems on the nexus 7, unless I'm misreading.

Thanks again for taking the time to reply.

Happy New Year.
[Nexus 7 Android Development] Nexus7_tilapia:
Also(+) Tilapia supports SMS, it does only need to install an appropriate app.
[Nexus 7 Android Development] Flounderist:
5.1 is the latest stock firmware available for grouper. You will find file and flashing guide here:

https://developers.google.com/android/images

Updated firmware is better because you will flash twrp and ROM on top of latest bootloader and device fingerprint available.

I used both Lineage and AOSP ROM on grouper and in the latest times I stick to AOSP. I would recommend it.

Happy new year too!
[Nexus 7 Android Development] joshaspinall:
It Works!

Stumbled on your build after wanting to revive my creaking Nexus 7 2012 for my kids to use.

Works a treat! The most speedy of the builds I've used since Official support ended. Keep up the good work! :good:
[Nexus 7 Android Development] js-xda:
Thank you, [MENTION=2188693]AndDiSa[/MENTION], very much for the continued support of this device - even with your own being broken!

Out of curiosity: I realized a while ago that Android 7 is no longer supported by Google. How does it work with getting updates for Android 7.1.2? Is it a simple backport of patches? Is it something that is organized in the AOSP community? Are all (applicable) patches of Android 8+ backported to your build? I tried but didn't find a clear answer on this one. And don't get me wrong - I am not panicking about maybe missing a patch but I like the idea to have a rather up-to-date system instead of one that is out-of-date for years. ;)
[Nexus 7 Android Development] AndDiSa:
[MENTION=9384875]js-xda[/MENTION] since my device is broken I am fetching the security patches from LineageOS (as long as there are no conflicts). Fortunately they are still supporting 7.1.x by backporting the 8.x patches to 7.1.x

I am not sure how long they will still support 7.1.x as Google will most likely drop even 8.x within the next year.
[Nexus 7 Android Development] js-xda:
Thank you for explaining! In that case, let's keep fingers crossed for our old-timer Nexus 7!
[Nexus 7 Android Development] NikoNik7:
Good ROM. Only one problem stretches from version to version.

The system goes into reboot after connecting to the Internet through the Hot Spot of the mobile phone. As soon as the application upgrade begins, so restart. Not on the first app, so on the second.

It would be great to get rid of her. I suspect that the problem is due to the inability of the Wi-Fi driver to correctly process a significant change in the speed of the mobile channel, which is heard through the Wi-Fi point.
[Nexus 7 Android Development] HaRdC0r3:
Having a small issue... Bluetooth volume isn't easy to adjust.... Changing the Bluetooth absolute volume in dev options doesn't stay checked. It always resets to unchecked when you back out of the options.
[Nexus 7 Android Development] Uraeuslair:
I've formated the Nexus 7 using TWRP 3.1.1, pushed the aosp_grouper-7.1.2-ota-20191215.eng.ds.zip (212Mb) and the open_gapps-arm-7.1-pico-20200107.zip (146Mb) and flash them using TWRP. However, when I boot the device, there are no google apps: no Google Play Store. I am doing something wrong? Thanks in advance
[Nexus 7 Android Development] AndDiSa:
You have bootloop issues when you try to start recovery? That's strange and it should not happen. Bootloops in the ROM part could be caused by the integrated SuperSU in your ROM. The /system partiton is very full and SuperSU should be installed systemless. I don't know how you've integrated that. Nevertheless recovery shouldn't be affected.
[Nexus 7 Android Development] tpuserhp:
I believe he is getting the same issue as I reported in post #9. When I tried to boot into recovery after flashing the rom, I was getting repeated error msgs. The only way out from this loop is to issue adb reboot recovery and flashing twrp again. I believe others ran into this situation as well. Hopefully, this can be fixed.
[Nexus 7 Android Development] dareino:
I updated from 6 with ParrotGeek mod....my system is super slow. Should I have deleted the mod first? I followed the OP's recommended flash.....ext4 sys. All seems to work tho except Adaway.

thxs
[Nexus 7 Android Development] AndDiSa:
I didn't try parrotmod yet so I cannot say what is remaining from it when you are flashing a new ROM. I suppose everything should be wiped out. Probably you can take a logcat to see what are the problems.
[Nexus 7 Android Development] millosr:
I succeed to fix recovery problems.

They were caused by applying recovery patch from init.rc.

I have commented part that creates that patch: https://github.com/millosr/android_build/commit/d5a6bf6811a273652c9a68f3a143f7f34a011d5a

I've also commented flash_recovery service in init.rc : https://github.com/millosr/device_asus_grouper/blob/nAOSP-7.0/patch/system_core.patch.2

I've tried to build ota with TARGET_NO_RECOVERY = true, but didn't have success with it.

BTW: I don't have SuperSU but integrated Superuser with android App Ops. It isn't big. I use opengapps pico. I have 120MB free on system partition after flashing.
[Nexus 7 Android Development] tpuserhp:
Great findings. Those 2 error messages were the ones I got repeatedly when trying to boot to recovery. Hope your fix will be incorporated in the next build of the rom soon. Thx.
[Nexus 7 Android Development] AndDiSa:
[MENTION=6754437]millosr[/MENTION] thanks for the hint.

On AOSP 6 I was using my own "patched" build environment and I switched to the AOSP one only now, so I didn't notice that there is such a recovery installation precedure built in now ...

As I normally flash the ROM by using fastboot I didn't even notice these problems.
[Nexus 7 Android Development] 239:
What do you mean by does not support it? I changed the file system for data/cache from ext4 to F2FS without problems. Will AOSP 7.0 work on ext4 without lagging?

Do you plan to update your build or is it stabled enough so far?
[Nexus 7 Android Development] AndDiSa:
TWRP may not be able to mount /cache and/or /data if you use f2fs which may cause some issues because /cache is used by TWRP, too.

Android 7 AOSP on Grouper is updated to Android version 7.0.0_r14. All the security patches from October are included (as far as they are applyable for Nexus 7). In addition I've applied some bugfixes (NFC, bluetooth). Nevertheless it's still in beta state, i.e. you might have to deal with some issues ... ;)
[Nexus 7 Android Development] n3kf:
Thank you....
[Nexus 7 Android Development] donjamal:
how on earth do i root this thing? it keeps bootlooping no matter what i try... can you please help with step by step instructions? thanks!
[Nexus 7 Android Development] AndDiSa:
I am doing it in the following way:

- Boot into twrp recovery

- install ota-zip

- install gapps

- install SuperSU (optional, but if you install, you need to install systemless!, otherwise chances are to create a bootloop)

- if you come from a different ROM, wipe data and dalvik

- reboot
[Nexus 7 Android Development] donjamal:
thanks but the update process is clear and it works. only issue i have is the systemless root. that kills the nexus and puts it into bootloop bed :) for that i need the instructions cuz i tried op and it does not help
[Nexus 7 Android Development] AndDiSa:
Did you have already a look at post #2?
[Nexus 7 Android Development] donjamal:
yes, reboot into recovery, open cmd, type in command, exit cmd, flash supersu --> no go

same but typing in command in TWRP terminal, exit, flash --> no go.

so either i don't get something or something's wrong
[Nexus 7 Android Development] shibadoo:
Flashed the new tilapia build. Everything including radio seems to work. Not really tested everything, but looks great! So thanks again for your work und for supporting our beloved device!
[Nexus 7 Android Development] robgriff:
OK, I've now got it working the factory reset didn't work because it just got to the standard launcher with no gapps so I had a thought that someone has mentioned having to reboot into twrp after wiping system so I did that and it worked...

---------- Post added at 02:09 PM ---------- Previous post was at 01:45 PM ----------

I don't know if this is directly related to this latest ROM but when I got it working there was no search bar on my Google Now launcher home screen and what I had to do was to add a widget and then it asked me to grant permission to google to read widget data and the search bar reappeared, in my case I added a third party widget so it might be because this was the first time a non Google widget has been added but it just seems strange to me that this permission was what was stopping the search bar from appearing and I've never had to do that before

Yeah I've found that I have to Flash the Rom - Reboot into Recovery a second time and Flash Gapps & SuperSU.... If I try to Flash Rom and Gapps in the same Recovery session I have issues with Play Services and the Store etc etc.

Sent From My SM-N910W8 ??
[Nexus 7 Android Development] robgriff:
Glad it's not just me then, I've had a few problems with gapps not working and the last time I thought I fixed it by formatting /data after I found an error on it in f2fs and converted it back to ext4 but my thoughts now are something to do with /system and gapps so I'll always reboot after I wipe system from now on

---------- Post added at 06:33 PM ---------- Previous post was at 06:29 PM ----------

But you said you rebooted after flashing the ROM and I rebooted before flashing anything (ROM, Gapps and SuperSU) and it works so I think the wiping of /system somehow isn't complete until it's rebooted and for some reason gapps is the one to complain!?
[Nexus 7 Android Development] fernandoarafat:
Was having issues downloading from Chrome. After giving permission for storage a message would appear at the bottom of the screen saying "download failed due to missing SD card". Not sure if related to the MTP Host issue when opening the Downloads app. Tried wiping data of Download Manager and Downloads app and also adding permission to those two but the option was grey. Installed Dolphin Browser and it downloaded correctly, but the file was not appearing in Downloads app, but when I looked in the Download folder with Solid Explorer, the file was there. Deleted the Download folder with Solid Explorer and created it again, now Chrome downloads correctly. Not sure what solved the problem, if using a different browser or re-create the Download folder.
[Nexus 7 Android Development] allmightyones:
Ohh its a pitty... The main use of my nexus is to screen mirroring live sports from kodi to chromecast.

Ill wait and hoping that you solve this little isue because i read marvelous things about your work with this Rom.

May be a graphical glitch. I have airplane mode on on my Tilapia, but the Celular Network Signal, on battery stats, is showing a red bar. Shouldn't it look blank if cellular network is off? The device is sleeping properly and not getting drains from cellular network. I'm on the previous ROM, not the 12/13 update.

Stream works well but download does not with the latest build (20161213). You should also keep in mind that not all titles are available for download anyway.
[Nexus 7 Android Development] adstraylight:
Thanks for adding this, sadly though it appears not to be working.

It's odd, even though the backlight values are now accessible, they seem to have no effect on the brightness of the screen. As though the driver is simply failing to pick them up. Is there perhaps another patch that works in tandem?

This works as expected. OpenGapps Pico only installs the Play Store, no additional apps - see https://github.com/opengapps/opengapps/wiki/Pico-Package

You can add the other Google Apps using the Play Store...

---------- Post added at 06:15 PM ---------- Previous post was at 06:08 PM ----------

I don't think that this is necessary unless the device you download the Gapps Pico installer zip package to is too small.

AFAIK Gapps package contains content for different devices/screen resolutions, but only installs those which are required for the target platform, so the installed footprint does not increase the same way the installer zip file did. Proof points: recent install with bigger Gapps package worked for me and [MENTION=4267345]Uraeuslair[/MENTION].
[Nexus 7 Android Development] Uraeuslair:
The problem was that I skipped the step of rebooting to bootloader between the rom flash and the gapps flash. For other flashes that I've performed to other Android devices, this was never a required step. It was weird because I was not getting any error while flashing or booting the tablet, I was just not getting Google Play Store. Thanks a lot for the help

Hey, I actually use my grouper almost always with a stereo Bluetooth device connected, either headphones or loudspeakers and I never had issues adjusting the volume, however I'm not touching the dev setting in regard to the "absolute Bluetooth volume", may I ask why you use it, do you have Bluetooth volume issues like stated in the short description next to the option in the menu?

If updating with previously installed GAPPS, is it actually mandatory to update also GAPPS if staying with the same old but small enough GAPPS package? I did the GAPPS update always for this ASOP build. But looking e. g. to updating LineageOS OTA, GAPPS are never updated in this step (system update). But the Google services are updated anyway in between system updates.
[Nexus 7 Android Development] ferro_sk:
I did not face any issue when after flashing grouper ota update 20200112, I re-flashed pico gapps package downloaded yesterday (20200117, size 146MB). So I think it is not necessary to use old pico package with smaller size as was discussed is some previous posts...
[Nexus 7 Android Development] fsw_informatrix:
Just adding a quick "me too" here: I also downloaded the last standard Pico package straight from the Open Gapps page and flashed it after the ROM, without any errors. I did reboot to Recovery in between though, something I never did before, out of sheer lazyness ;) so I don't know if that helped...

I still have the problem of the crashing setup wizard. I downloaded and installed the latest Open GApps for Arm/7.1/pico, but still no luck.

However, I can't do anything before finishing the setup wizard, so I am not really sure what do do here.

There's was a flashable zip floating around in this thread that bypasses the setup wizard I think.
