Hello and thank you for your Work!

How can i get my USB File Transfer working after Update on my Nexus7 Wifi 2012 ?

I can select "File transfer only" wen plug in USB Cable, but it does not work on my Win7 Computer.

I allways need to restart the Device in Recovery Mode to upload Files to the Tablet.

It also did not work in my Drohne App, wen i plug in USB i got asked if i want to allow, i press Yes but there is no Video Stream sending over USB File Transfer.

To explain a bit more, i connect my Tablet with the Drohne over App and USB Cable to remote Controller.

Normaly the App get the live Video stream from the Drohne Remote Controller over USB.

After updating Firmware this is not working anymore. I think there is something wrong with the USB File transfer system, as i also are no longer able to send Files from my Computer without restarting the Tablet to Recovery Mode.

Only in Recovery Mode File transfer over USB works fine.

So im in hope some of you understand my problem and maybe have a solution ?

As my Tablet was never so fast before, as it is now after the Update and i want to keep this Firmware :)

thank you and stay healthy!
[Nexus 7 Android Development] AndDiSa:
@spoonweg you need to use either ptp or mtp protocol to transfer files between PC. This was changed in Android 7 but I heard already from different sides that Windows sometimes has issues to connect via ptp / mtp.

Unfortunately I cannot help you much as I am using Linux almost all the time ... probably someone else here from the community can help out?!
[Nexus 7 Android Development] ev-olution_net:
Make sure you enabled developer settings. If you already did that,connect your tablet to PC and go in to developer settings, find "Select USB Configuration" and change it to MTP.

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!

Have a wonderful Christmas time and a happy new year and most important within this times: stay safe!
[Nexus 7 Android Development] Turtle Trader:
hi, where i can found tutorial for install this OS? thx before
[Nexus 7 Android Development] AndDiSa:
Did you check already the OP?
[Nexus 7 Android Development] username one:
Grouper and MicroG installed with Magisk. Everything seems to work fine. Thank you very much for the efforts you've made! Merry Christmas and Happy new year!
[Nexus 7 Android Development] Luckz27:
MicroG Grouper version amazingly smooth, man!!

P.S. AndDiSa, is there a way to offer you a coffee, to thank you for your amazing work?
[Nexus 7 Android Development] dark0shark:
Flashed December version of grouper, also new TWRP version 3.6.0, - works great!
[Nexus 7 Android Development] :
Grouper + MicroG working fine for me. It took a little longer than usual/I was expecting to boot after dirty flash - but it got there!

Btw, I still have to flash a Magisk zip as the app doesn't offer the 'direct install' option, and I checked that it had storage permission. No problem though, it all still works :)
[Nexus 7 Android Development] momentoid:
Successfully CLEAN installed Dec (2021-12) ROM with GApps (2021-12-09). Also updated to TWRP 3.6. Tested my regular apps. All good👍

Also noticed "Settings>Backup&Reset>Backup account" is operational. Thanks @AndDiSa

Silly story: After Factory reset, ROM and GApps installs, waited an hour on "Setup as new device" before realizing I had forgotten to Wipe Dalvik cache.🤔😀

Edit: @dark0shark 's post lead me to TWRP 3.6 update.
[Nexus 7 Android Development] :
I didn't spot that, thanks for the nudge! ;)
[Nexus 7 Android Development] marty_bebop:
Grouper: Dec MicroG ROM, Magisk 23. All good - in fact, seems slightly 'snappier'.

It's great these older devices are being kept alive - listening to online radio on it now.

--

I tried installing TWRP 3.6 via the app and also via TWRP itself - got 'not enough memory' messages. No idea what that's about. Any suggestions? I see others have installed it without problems.
[Nexus 7 Android Development] dark0shark:
You can flash TWRP .img file within TWRP while selecting "Image" as type and "recovery" as partition. Then go back, back and reboot into recovery again. That's what I did.
[Nexus 7 Android Development] momentoid:
I used adb and fastboot in Android/sdk/platform-tools, followed the instructions on TWRP site.

Just remember the downloaded <long-twrp-img-filename>.img must be renamed as twrp.img before flashing with fastboot.

Hope this helps.
[Nexus 7 Android Development] dookie23:
Thanks @AndDiSa. I installed the MicroG Grouper rom and flashed MicroG on system. It works perfectly even without root. Performance is great! Thanks again!
[Nexus 7 Android Development] SolarPlexus:
Hi,

thanks for the Rom, I would like to restart my old Grouper. Unfortunately I stuck at a point, and Im not sure if I'm blind.

I wanted to use the Rom without the GApps, so I tried to install some apks direktly, but I must say: I did not find a way:

- there is no file explorer to select and start the installation of such a apk

- The "Download" app did not show any files wich I had copied to the device.

- The try to do it via ADB shows me an ugly Error where I'm also stuck:

adb: failed to install F-Droid.apk: Error: failed to write; posix_fallocate failed: ENOTSUP (Operation not supported on transport endpoint)

So which way I can chose?

Thanks,

MP
[Nexus 7 Android Development] js-xda:
There is actually - somewhat hidden - a file manager in the ROM. See my earlier post below.
[Nexus 7 Android Development] SolarPlexus:
Thanks again. I've tried that also, but after giving permission to trust unsafe sources for installation, the answer of the system ist just "App not installed"...
[Nexus 7 Android Development] js-xda:
Hm, strange. Are you sure the APKs are OK? Can you install them on a different device? Might sound silly but I had the case of a broken APK just yesterday.
[Nexus 7 Android Development] SolarPlexus:
Yes, packages are ok, used also now on my phone...

I've tried now also to implement pico Gapps (used the Installationen way described in main thread), but also there when I tried to let something install with the playstore the system told me not installed at the end...

It looks like something is not included in the OTA finally, for example I did not see package installer.apk in systems/App.... Sad as it looks like smooth in a generic view..
[Nexus 7 Android Development] momentoid:
Fyi, I have been using this ROM with pico GApps for over a year, updating monthly with security patches, without any problems. The issue must be elsewhere.

It takes a few minutes for Play store to update itself after completing "Setup as a new device." Hope this helps.

If you want me to test install a specific app from Play store, let me know.
[Nexus 7 Android Development] SolarPlexus:
Thanks for the proposal. I think it has something to do with the latest release, as I have started with that, and not a previous one. I've now choose the unofficial Lineage, and there I have absolutely no problem to install, and go further. So for now I will use that. Thanks for the try of help!
[Nexus 7 Android Development] Luckz27:
Hey guys, is the “swiping gesture” not working in the AOSP keyboard or is it just my problem?

I'm on December microg grouper version.

P.S. I'm talking about this: (in this screenshot, working on Swiftkey)

I found the solution (missing a Google lib: libjni_latinimegoogle.so) but it's not working for me:

How to fix AOSP keyboard gesture typing in CyanogenMod 12 and 12.1 - Ruben Alamina

Gesture typing is super useful and one the things you will miss the most if it somehow does not work. CyanogenMod 12 and 12.1, based on Android 5.0.2 and 5.1.1 respectively, started depending on a variety of Google Apps packages made by third parties instead of providing an official or...

@AndDiSa may you help me to understand what the problem is? I don't know what I'm doing wrong.
[Nexus 7 Android Development] Flounderist:
FYI apps are installing properly on my gappless Grouper with latest build (tested this morning).
[Nexus 7 Android Development] AndDiSa:
@SolarPlexus can you confirm that you've downloaded and installed one of

aosp_grouper-7.1.2-mg-ota-20211208.eng.ds.zip (MD5: 3d4778b5582facb453b2ce54026640a7)

aosp_tilapia-7.1.2-mg-ota-20211208.eng.ds.zip (MD5: eb4afe6e10537c45df30808e5d043aa3)

for the MicroG installation and that you wiped data if you had installed a non-mg-version before?
[Nexus 7 Android Development] Flounderist:
Please be aware that I am using the vanilla build. No Micro-G enabled at all.

Installing apk from storage went fine as usual.
[Nexus 7 Android Development] AndDiSa:
@Luckz27 as you already quoted in your link: libjni_latinimegoogle.so most likely is not contained in the MicroG package (I am not even sure whether it will be installed using the Gapps package).

If you would like to get swiping support I suppose you will need to install a different keyboard application ...
[Nexus 7 Android Development] SolarPlexus:
Yes I can confirm all that steps (I used the first one from grouper). I really go step by step from the manual Wich is written in first Post, and read also bevor the followed one's so not to miss something...

Anyhow, the latest lineage works well so far now on my grouper. I did not check the checksum of your file, so maybe there are some bytes lost, I don't know.

Maybe I try you custom for the next update if new security bugs will be published, then I come back here. I can not test it now with a new download, as now my wife use the tablet, and you know, never put a way something from your wife what is working fine :-P

BR and fine X-Mas days!

[Nexus 7 Android Development] Flounderist:
Wise guy.
[Nexus 7 Android Development] Luckz27:
Yep, libjni_latinimegoogle.so is obviously not included in the MicroG package because it's a Google's library but it is in the Gapps, even the Pico one's!

Anyway, I tried to use other keyboards but the AOSP's is the most RAM friendly for this tablet: so, I tried to solve the problem and make the glide typing works in AOSP keyboard too but it seems that the fix I posted in my previous post doesn't work in this ROM.
[Nexus 7 Android Development] momentoid:
I don't about microg version, but I'm on GApps version of the ROM and able to use swipe type with GBoard app available in Play store. After installing, enabled it in Settings> Languages&input> Virtual keyboard.
[Nexus 7 Android Development] Luckz27:
Thanks but Gboard is not the same thing as AOSP keyboard: if you had flashed even Pico Gapps, so you have the glide/swipe typing working in the AOSP keyboard too.

In the Microg version, a proprietary Google's library is missing, so no glide typing.
[Nexus 7 Android Development] momentoid:
Yes, something's missing in AOSP/pico GApps, too. Although AOSP keyboard settings has gesture typing enabled by default, glide typing doesn't work. I'm so addicted/spoilt with swipe typing, since the early Swype days, I had to install Gboard to get glide typing.😀
[Nexus 7 Android Development] RealPsygnosis:
why if I start developer option I can't access files on windows? Everytime I turn on dev option I can't explore the storage.

And even if I turn the option off I can't see storage in windows anymore.
[Nexus 7 Android Development] AndDiSa:
Android versions 7.x and greater do support mtp or ptp over usb only. You need to select the correct protocol and you need to have mtp/ptp support installed on your Windows PC then file transfer should work.
[Nexus 7 Android Development] Snype32:
I just dug out my nexus 7 after finding out I might be able to update it a bit and make it a bit more usable. Mine is the 2012 version. What is the latest version on android I can put on this thing? Poking around the web, it seems like it should be able tor run lineage 17.1. I have found guides how to do it, but cant find the correct version to download. lineage 17.1 looks to be android 10. Can this thing actually run that? Or am I missing something? Thanks!
[Nexus 7 Android Development] momentoid:
Hi, welcome to the thread. This is about AOSP based Android 7.1.2 ROM for Nexus 2012, both variants. The latest version includes Dec 5 security patches. Page 1 details links to download and how to install it. The device with this ROM works great.
[Nexus 7 Android Development] Snype32:
thanks for the reply. I think my nexus is toast. Something happened when I was transferring files off of it. Totally crashed. Couldn't mount partitions. twrp couldn't fix it. Now it wont even turn on. When I have the usb cable plugged in, it tries to install an APX driver.
[Nexus 7 Android Development] AndDiSa:
@Snype32 your device is in APX mode which can indicate severe hardware issues, but it can also be the case that e.g. the vol-button is stuck as you can enter APX mode when pressing both (vol+ and vol-) buttons in parallel while booting. To exit APX mode you need to press the power button for more than about 20 sec. and without any cable connected ... unless there is really a severe issue with your device. Good luck!
[Nexus 7 Android Development] Snype32:
Thanks for the info. I think I have tried all that already. I'm pretty sure it's toast at this point. I was using a software toolkit to try to restore it back to factory original to start over. It got hung up at flashing bootloader. Waited forever before I finally gave up. Tried to restart...no go. Before all this I was trying to back up files off of it. Found out one of the usb ports I was using on my computer had an issue. I'm wonder if it fried it somehow.
[Nexus 7 Android Development] TitanTyrion:
@AndDiSa

I flashed the latest ROM with latest Gapps and your Information with gapps-config-tilapia.txt on /sdcard worked fine for me.

Thank you...
[Nexus 7 Android Development] Baonks81:
I installed aosp_tilapia-7.1.2-mg-ota-20211208.eng.ds.zip (MD5: eb4afe6e10537c45df30808e5d043aa3)

It runs smoothly. Thanks
[Nexus 7 Android Development] AndDiSa:
Hi guys,

I hope you and your families entered safely the new year and everything is fine for you.

Just to inform you: I'll skip the January 2022 build as there is only a single patch to be applied. For those of you who are building from the sources, it's already pushed to my repository.
[Nexus 7 Android Development] tbmmbt:
Haven't checked in here for a while and just wondered what is the latest version for Grouper? Sorry if it's a stupid question but on the very first page of this thread it says Build 20211105 but looking back through most recent posts it looks like it's on a newer build.

Does the first post always contain the newest build or is there somewhere else I should look for the latest version?

And thanks for the continued work AndDiSa!
[Nexus 7 Android Development] AndDiSa:
@tbmmbt sorry, I didn't update the OP yet. Yes, there is the build from December 2021 already available.

I'll do the update as soon as I find time.

Edit: done!
[Nexus 7 Android Development] tbmmbt:
Thank you, no problem. Just wanted to make sure I was using the right image! Thanks again for keeping our old device alive :)
[Nexus 7 Android Development] camp0s:
Just a little note from my experience: it did happen to me, always used the Pico version and when I updated during the holydays (from maybe this spring) this time this solution worked for me (y)(y)(y)
[Nexus 7 Android Development] BeeJ1109:
Hi campOs,

Please read the info on Page 1. Latest Pico Gapps is too large that is error 70 means,

Download the modified version, smaller will then work.

After bootup, you can add any Google apps to update to latest version.

Worked for me on my Tilapia Tab.

Bad post.
[Nexus 7 Android Development] breaktheblock:
Hi All,

A general question how are people finding battery life?

I have previously use this ROM on grouper and used to get around 20 days in standby if not used with battery saver on, now it is a lot less, is this due to all of the patches that have been added or maybe my grouper battery is dying?
[Nexus 7 Android Development] AndDiSa:
@breaktheblock I noticed that battery live depends on Google Services (not sure whether you have installed them or not), but if for example syncing calendar / contacts / ... are stuck (for what ever reason) battery is running out very fast.

I from my side did not notice a big change in power consumption within the last weeks / months ... but I also need to say that I also did not really test that behaviour, as my device is frequently connected to the PC and so it's automatically re-charging.
[Nexus 7 Android Development] breaktheblock:
@AndDiSa I only use the Rom with fdroid so no Google services. I run the fstrim app with SU from Magisk, the only other apps I have are red moon and Spotify. So I'm unsure why battery is so quick to run down (less than one day), previous builds the same so this is making me wonder if it is my battery.
[Nexus 7 Android Development] breaktheblock:
The latest after 1 day and 10 hours in battery saver mode the tablet estimates I have 6 days left. This is reduced from previous roms from this thread, as I have previous observed 18-20 days but still the battery is better than I thought at least at this moment.

When doing a wipe with TWRP does this wipe the "memory" of battery stats?
[Nexus 7 Android Development] D F:
I come from a Cyanogenmod version. I have installed it a few years ago. Battery life was awful with that version. It may have been I broke something during installation. This was the reason I haven't used the tablet too much. Now, it came back to life. With screen of, I can see an obvious improvement but that is because I had a defective installation, I guess. Now, with screen off, the battery stayed at 100% for a day and then, went to 99% after a day which is pretty normal for me.

So, I love this software version, I installed Spotify, Youtube and Youtube Music and I am thinking of using the tablet as an audio source for parties with friends,only provided battery life is good, because I need at least 4 hours of SOT. Good thing about my Grouper is that you can charge it while listening to music without other improvisation.

I found an issue though: bluetooth won't receive files and I can't connect the tablet to a bluetooth player. Is this something particular to my configuration, or a general bug?
[Nexus 7 Android Development] AndDiSa:
I just did a bluetooth file transfer between my Pixel device and the Tilapia device without any issues. So it doesn't seem to be a general bug.
[Nexus 7 Android Development] D F:
I see. What could be the problem? Because I can see the tablet in other devices.
[Nexus 7 Android Development] AndDiSa:
hmmm ... did you check in the logs? Do you get any error message displayed?
[Nexus 7 Android Development] D F:
I didn't, but today I managed to send and receive a picture. Problem is I still can't connect it to my player. It asks for a PIN code, despite the fact that the player is in pairing mode.

Where can I find the logs?

Also, what browser do you use with it? Brave is too slow.
[Nexus 7 Android Development] Stephco03:
Hello,

The ROM installs without problem.

But I want install Opengapps, I have a error :

"Insufficient storage space avaible in system partition"

What should I do ? I am blocked :,(

Thanks you in advance for help me

It's OK with Beans Gapps Mini, thank you, but it's weird for open gapps :-\
[Nexus 7 Android Development] AndDiSa:
@Stephco03 did you check a few messages ago the post from @camp0s ?

He had exactly the same issue ... 😉
[Nexus 7 Android Development] D F:
Copy in the same folder with Gapps, the file in this post.

I had the exact same issue.
[Nexus 7 Android Development] G_Bot:
Im using gapps with the microg package. I installed microg through magisk and im using nanolx patched playstore from github. Everything works, Gps Works, and all gapps and paid apps. and it has good battery life. Its easy to install through magisk microg installer zip. It is a great rom i use it daily. Thanx for this development. 👍
[Nexus 7 Android Development] wvanstraalen:
I am also interested in using it with the microg package.

Does it work with chromecast if I don't install any gapps?

Like, just the base ROM and MicroG zip through the Magisk installer. Should that be enough to get the send to chromecast functionality to work in apps like Pocket Casts or whatnot?
[Nexus 7 Android Development] camp0s:
Just something happened to me: with TWRP 3.6.0_9-0 when installing the latest ROM (20211208) I get: android AOSP install update process ended with ERROR: 7.

The tablet, grouper, was completely formatted (advanced wipe, all partition wiped).

I'm trying to follow the suggestion in post #2..

Reverting back to TWRP 3.5.2_9-0 the installation went forward without problems.
[Nexus 7 Android Development] camp0s:
UPDATE: the launcher, after a fresh install (20211208) keeps crashing o_O

UPDATE #2: after many wipe, format and so on it got installed and does not crash anymore.

--> I lost write permission on the Data directory. I can mount and copy files when in TWRP, but in android after installing Magisk for the root, no file manager have write/delete permission on the /sdcard path :oops: - what did just happen?
[Nexus 7 Android Development] :
Thanks for the pointer, I'll give that a try next flash/update.
[Nexus 7 Android Development] wvanstraalen:
Also am struggling to find the option for adb over wifi in the settings, which are not in the same place as on LineageOS. Maybe I've overlooked something. Furthermore, the chromecast probably would still need the gapps installed and would prevent the switch to MicroG proper. Which is sad.
[Nexus 7 Android Development] wvanstraalen:
ADB wireless only works for me after I have connected it via USB. Furthermore, with the microG fully installed and all the checkmarks on in the self-test, the chromecast audio still doesn't work.
[Nexus 7 Android Development] AndDiSa:
@wvanstraalen this is normal behaviour for Android version <=10

chromecast audio should work, but I will re-check.
[Nexus 7 Android Development] sephren:
Yes. Guess TWRP just didn't recognize the installed image as the new OS. Restart was as expected, first bootloader, then android logo, first start took a while, no reboot loop or something like that.
[Nexus 7 Android Development] shaggyskunk:
Ok - did you Flash Gapps at the same time - or you rebooted just the Rom first and back into recovery and flash Gapps? (that's what I've had to do the last couple of builds). Very strange regardless... I've never seen this before.

Well I also got a recovery log so I'll let bigbiff know

Thanks again!
