Thank you - I'll check that out.
[Nexus 7 Android Development] killeriq:
there are no new versions of LineAge? last is still the one form 2017? thx
[Nexus 7 Android Development] CamoGeko:
My post above says I'm running the last build from 2018.

Yes it still works fine, and no I don't think there's any new builds.

This ROM runs great.

Initially I was getting lots of crashes and forced restarts but ever since I disabled MTP host it seems to have solved this so and at the moment the tablet runs well. Thank you.
[Nexus 7 Android Development] breaktheblock:
I spoke too soon, games run but really slow?

I suspect it's the lack of RAM and the tablet is fundamentally flawed?

Is there anyway to fix?
[Nexus 7 Android Development] CamoGeko:
Yeah the fix is... don't try to play games on an 8 year old tablet with 1GB of RAM lmao!

Did you really think that was going to go well? :p

great job on this rom, waiting to see android 10 on our tablet [emoji12]

[Nexus 7 Android Development] breaktheblock:
Well games like tomb raider 1 classic and riptide GP run no problem then others like retrobowl and pac-man run slow.

I can also only run Spotify for a short while before it force closes its self.
[Nexus 7 Android Development] skugpezz:
Hi, I installed this rom and noticed system is using 23GB of storage. Is this normal?

Thanks
[Nexus 7 Android Development] fsw_informatrix:
That's really weird... You can see on the picture how system looks on my 16GB grouper, even if I think you have the 32GB model, that's not normal at all! I would start over and do a complete wipe + clean flash...

EDIT: Sorry, wrong thread! I switched a long time ago from this ROM (which is not maintained anymore) to AnDiSa Nougat AOSP (which just had the April security patch, even if he doesn't own the device anymore!!!) you should give it a try :good:
[Nexus 7 Android Development] fsw_informatrix:
Old tablet = old games ;) I could play with very good performances GTA III and GTA Vice City on my grouper. I just hated the touchscreen controls, but that's me (PC gamer) :D
[Nexus 7 Android Development] breaktheblock:
I just don't it odd that the more graphically demanding games are running ok then then retro games are not unless it how these apps are written?

Spotify is baffling me also, I'm guessing here with very limited knowledge but I think the cache gets over loaded as when the grouper downloads too much to the cache it just reboots?
[Nexus 7 Android Development] fsw_informatrix:
It's possible for both cases, it's hard to say... But if I were you (and I don't want to hijack this thread), I would give AnDiSa AOSP ROM a shot: it's still maintained, stable and really great performance wise
[Nexus 7 Android Development] skugpezz:
Could someone have changed the partitions before I got the tablet?

I see the system partition is 23.10GB.
[Nexus 7 Android Development] breaktheblock:
Good suggestion but have already tried this with identical results. If I need to adjust everything to make the ROM more stable after flashing is another question but I will try to ask in AnDiSa's thread.
[Nexus 7 Android Development] skugpezz:
I did a format in recovery. Seems to have fixed the issue. Now I have 27GB free :D.

Thanks for pointing me to that rom. I have installed it. I dont like the look though.
[Nexus 7 Android Development] fsw_informatrix:
You're welcome :) for me too at the beginning, it was really dry compared to LineageOS, but I did get used to it and it's so light and fast on our old lady! The only thing I'm still missing is the advanced restart... And I think you can surely make it prettier with stuff like Nova Launcher, but I never tried it, because I personnaly don't care much about the look ;) Hope you will enjoy it nevertheless...
[Nexus 7 Android Development] :
I use Nova Launcher. It sometimes lags a little but is my pick of launchers (of those I've tried anyway!)

I use a TWRP app for advanced boot options (recovery, bootloader) on the rare occasions that I need it. It certainly beats getting cramp in my fingers trying to hold down the required combo of buttons!
[Nexus 7 Android Development] fsw_informatrix:
Yes, the official TWRP app is great: of course for downloading + flashing directly TWRP from the Android system and, as you said, because it offers to reboot to recovery, without using the awful combo keys, that I miss half of the time ;) but it doesn't work on my two old Sony devices (because of the strange elf format) so I had to dig further and noticed that the advanced menu of Titanium Backup also offers reboot to recovery :) I hope those small tips can perhaps help somebody...
[Nexus 7 Android Development] nexusnagasi2017:
Congrats for your great work! Help needed ;) USB unrecognized!

Hello!

I own a Nexus 7 (2012 ,1st gen) and being confined made me unbury my sleeping beauty. I wish I could install LineageOS 14.1 on it but I have a desperate case to submit to the expert community:

When my Nexus 7 was under the original OS (Android 4) everything was functional and smooth, then I upgraded to 5.1.1. and everything became laggy and the worst is that when I plug it into any PC (different Windows versions, Mac OS Sierra, different Linux versions) it is not recognized any more ;-( The USB port of my Nexus is working because it is charging and it's also working with an OTG cable; I even replaced the port by a new one to make sure it was not faulty...) So here I am with a great tablet but the worst OS!!! An dI just can't do anything without that USB connexion. Do you have a clue to help me? Of course, I activated the Developer options and USB debugging; of course the tablet is not rooted ;-(

I tried, in vain, plenty of unrooting apks...(Towelroot, Kingroot..).

Of course I tried NRT but without USB recognition my Nexus is doomed!

Thanks for your help!

Hello!

Could you please link me to a page explaining how to install AnDiSa AOSP ROM from scratch? As I read your comments it seems to be the best OS for our old lady ;)
[Nexus 7 Android Development] fsw_informatrix:
Hi,

As I don't know any specific page on this topic, just follow carefully the first post of AnDiSa AOSP ROM, it should be enough https://xdaforums.com/nexus-7/development/rom-android-7-aosp-grouper-t3467514

If you find AOSP too "dry" for your taste, I've just noticed today a new unofficial CM14.1 ROM (but just for grouper, Wi-Fi only) here https://xdaforums.com/nexus-7/development/rom-cm14-1-nexus-7-2012-t4073169

I didn't test it, but it looks promising...

Good luck with your old lady :)
[Nexus 7 Android Development] beppemila:
hi [MENTION=4289856]street_dog[/MENTION] I've exactly the same issue. How did you solve it? Thanks!
[Nexus 7 Android Development] street_dog:
the "solution", for me at least, was to upgrade to next version. it might be connected with the battery won't charge more than 98% but a reboot and it charges 100%

that is the only advice i can give.
[Nexus 7 Android Development] beppemila:
thank you. I've just downloaded the latest version available here but I still cannot connect to wifi... same issue with every 7.1.2 rom I've tried so far (Lineage, AndDiSa and this one).

I don't have a clue about the solution...
[Nexus 7 Android Development] dizzymon:
Also keep an eye out for the usb port failure, the reason is the cable inside is loose, it's a 10-15 minute fix. Take off the back plate, remove a few screws and push the cable back. So check that if you are having charging issues. I've seen a few people selling or selling their old nexus 7 for that very reason and sent them the fix. I am always for reducing e-waste and re-purposing old hardware.. The tablet is perfect for playing music. Playing some of the games still works fine but most most new game are too demanding these days.
[Nexus 7 Android Development] street_dog:
I don't know if these tips will work, but it has for some.

check the time and date settings on your Nexus 7 and make sure that they are correct. some users have reported an issue with the date being wrong.

turn the NFC off by going to Settings > More, and uncheck the box that is next to NFC.

I am now running andisas aosp for some time and saw that i have turned off NFC.
[Nexus 7 Android Development] asmalldharma:
Weird question... Have you removed the back cover recently? If i remember correctly, the wifi antenna is in the back cover and connects by spring type contacts to the device. Sometimes they get bent and don't make contact anymore.
[Nexus 7 Android Development] beppemila:
I tried but no success. Thank you for your suggestions anyway! :)
[Nexus 7 Android Development] MikeN68:
Potential wifi fix

Beppemila,

Have a look at https://xdaforums.com/showpost.php?p=83546153&postcount=4378 from AndDiSa's N7 thread. Haven't tried yet myself but will need to soon. My N7 is still on the June release with rock steady wifi so not sure what was done to cause problems in later builds.
[Nexus 7 Android Development] killeriq:
Yeah this one works, tried ;)
[Nexus 7 Android Development] digixmax:
I am having the same issue -- the N7 only shows up in my Win 10 Windows Explorer only if it's in Recovery or in PTP mode but not in MTP mode.

Any pointer would be greatly appreciated.

TỊA
[Nexus 7 Android Development] uphall:
I just use PTP mode and transfer files to my pictures folder. Then use my file manager on the device to move the files to the appropriate location.
[Nexus 7 Android Development] Flounderist:
Mtp should be working in recovery mode. Just reboot to twrp while connected to your PC
[Nexus 7 Android Development] digixmax:
Thanks.

I had not used the N7 for a long while, so I forgot it's been this way (the issue and the recovery based workaround) since I first had LN on the N7.
[Nexus 7 Android Development] JT1510365:
Anybody having random reboots constantly with latest lineage os 14.1 on grouper? I am getting random reboots every hour or so and its driving me nuts. I don't have xposed installed and i have no apps installed except gapps. Any solution or ideas would be highly appreciated because i really love this rom and i want to keep it. Thanks.

I don't have gapps and the tablet runs solid.

[Nexus 7 Android Development] dizzymon:
You need to get the bootloader on there and after that it's pretty easy to flash it. Just look it up.

Hello i fighting for the Update on the Nexus 7. Now i have the Problem that i cant Install the GAPS. I get the Message that i dont have enougt space on the System Part. But im Using the Opengaps Pico. And when i tried to install the BeansGappsV2-N7-Mini-7.1.2-20190428.zip i geht another error :( has anyone an Idea?
[Nexus 7 Android Development] AndDiSa:
@dominikest you could try to use the method described in this post
[Nexus 7 Android Development] Vrpghm:
If you have knowledge, it is not complicated, you have to install a new recovery, the aosp 7.1.2 or lineage 7.1.2 romn work, I have been using the aosp for years, I am thinking of trying the lineage, there are orientation videos on YouTube, here too There is information and software, just be alert at every step, if you have android kitkat with the moviluncle software, download the recovery and install it directly or with mkttool software, install it from the pc, you must install the mkt and adb drivers so that the pc recognizes the nexus 7, greetings
[Nexus 7 Android Development] dizzymon:
Ran both Lineage and aosp. I find that Lineage is the most stable one. Less random errors.
[Nexus 7 Android Development] Vrpghm:
My experience with AOSP has been good, Android 7.1, it has updates every 6 months, the secret is to do the installation from 0, delete the system partitions, cache, data,..., DO NOT DELETE internal memory, down from 5GB to 3 GB when I make the backup, very fast after the clean installation
[Nexus 7 Android Development] vanseleem:
My tablet is bricked thanks to your OS.

After installing the Rom + gapps and used the tablet for two hours it started to b sluggish, i did a factory reset from the settings menu and the tablet never went back to life. Boot screen is all i have.

Bootloader is gone, recovery is gone. No key combination could ever bring those options back!

Just google screen and APX mode.

RIP my buddy.
[Nexus 7 Android Development] Vrpghm:
Why is it my responsibility or that of other members that you have not done the process correctly? How are there hundreds of Nexus 7 2012 or 2013 tablets running with different custom ROMs around the world? Rather, I tried to correct its failures, you have to download the official rom for the tablet, install it using flashtool, then you can install the Recovery twrp Correctly, I think it is like a brick because it deleted the OS, when you connect to the PC it recognizes it, you can reinstall its ROM Officially, instead of blaming others for your failures, solve them, my tablet broke quite a few times, I always recovered it, I didn't go out and blame anyone.
[Nexus 7 Android Development] vanseleem:
My tablet is not doing anything to install the official rom, pressing on the buttons doesn't direct me to bootloader or recovery, just a google logo screen, the only thing that shows signs of life that when i press power + volume up it goes to APX mode which is a black screen, and it shows on my PC that its APX mode, on the other hand in device manager the APX device shows exclamation mark and it's like the PC doesn't recognize the tablet, how am i supposed to recover this tablet?

I've been trying to find solutions for almost 20 days and nothing helps!

I had this tablet for more than 10 years and i never experienced any issues like this.
[Nexus 7 Android Development] AndDiSa:
@vanseleem you are not the first one whom's tablet bricked when doing a factory reset. It happened to me in the same way. Unfortunately the flash memory used for the Tilapia/Grouper devices is not of very high quality and if you are having bad luck it gets defective cells e.g. in the bootloader.

Nevertheless you are describing that the device is in APX mode, did you try to hold the power button *only* for about 30 seconds?

APX mode is useless for Grouper/Tilapia unless you have the appropriate tools and prepared for unbricking the device before it got bricked.
[Nexus 7 Android Development] vanseleem:
my tablet is just showing the google logo, i can only access apx by pressing the power button + up button,

i tried to use NVFlash to flash bootloader in apx mode using Ubuntu, but it ends up saying the below

Nvflash 3.08.1700 started

chip uid from BR is: 0x00000000000000000******

rcm version 0X4

Command send failed (usb write failed)
[Nexus 7 Android Development] AndDiSa:
@vanseleem nvflash is useless without previously beeing prepared for unbricking, e.g. mostly having extracted the correct keys from your device before it got bricked.

If you are really getting the Google sceen only then I suppose your device ended up in the same way as mine ...
[Nexus 7 Android Development] vanseleem:
Thanks
[Nexus 7 Android Development] mrrobbit:
Try using Wug's Nexus Root Toolkit to reflash to stock. I had similiar issues until I started using the tool
[Nexus 7 Android Development] vanseleem:
Just wanna make sure you had the same issue, no bootloader, no recovery, just a google logo with no PC detection unless i put it on APX mode, if yes can you walk me through the process? Thanks a lot
[Nexus 7 Android Development] Vrpghm:
It is not going to reinstall bootloader, recovery and Android from the tablet, you must download the official rom on a PC, download the flashtool software, the adb drivers, MTK for the PC, install adb drivers, mtk so that the PC recognizes the tablet, I I use Windows OS for PC, with the data cable you are going to flash from the PC to the tablet, you must open the flastool, load the scatter file from the official rom, on YouTube there is a video how to do the installation, so reinstall the official rom Before installing custom rom, you must CORRECTLY install the twrp recovery, it erased all the memory of the tablet, that is why it does not load any bootloader participation, recovery that should load if the installation of the rom or the gapps is incorrect, locate video how to install Recovery on Youtube or mobiluncle app on the tablet you can install twrp, trwp file in the root directories of the tablet, otherwise it will not locate it, before mobiluncle, you must root the tablet, good luck

do you have a pc or laptop? windows or linus operating system? Did you install Android adb, mtk drivers? tablet data cable?
[Nexus 7 Android Development] vanseleem:
I use HP laptop and all adb and MTK is installed properly on the laptop, windows 10 OS

I tried all what you said, installing the official Rom doesn't flash properly , the problem here is that the tablet is not recognized by the PC unless if ill make the tablet on APX mode, and i tried several flashtools to flash TWRP, the device is either not responding or it will just say waiting for any device.

I even tried to use the most ridiculous tool which is NVFlash and it respond with Write Failed.
[Nexus 7 Android Development] Vrpghm:
I had answered on Saturday, they deleted the answer, I don't see my answer, turn off the tablet, you connect the data cable to the tablet, you don't connect it to the laptop, now from the laptop with the flahtool program, you load the scatter file of the rom In flashtool, you press accept in Flashtool, then you connect the USB cable from the turned off tablet, you should start flashing, there are many videos of the flashing process on the Internet, locate them, use another Android device to test that the ADB and MTK are correctly installed, which tell you when it installs them that it is installed correctly, sometimes it is not true, whenever you connect the tablet usb cable it should appear in the device manager the Android usb added to Windows usb connections should make the Windows sound when you add new usb reviews
[Nexus 7 Android Development] Dshaww:
Got this running on my N7, however, I wasn't able to get Gapps-pico installed. I kept getting the message that there isn't enough space on the system partition despite using the config file provided. Tried via adb and from the tablet itself. Anyone else having similar issue?
[Nexus 7 Android Development] dizzymon:
Try the BeansGappsV2-N7-Mini-7.1.2-20190428 file. I used this with lineage-14.1-20210313-UNOFFICIAL-grouper.zip

[Nexus 7 Android Development] 007.4:
I'm running Lineage OS version 20170108 on my grouper with original kernel 3.1.10. I like it very much but as others have mentioned, it does seem battery hungry and I get random crashes in quite a few APPS. Would I be better off using version 20170122 or 20170101 instead? Or a different OS altogether? What is recommended now?
[Nexus 7 Android Development] aaopt:
Crash some apps and then pastebin a logcat. Then maybe we can see what is crashing and why. If it is about permissions you may need to adjust them manually in settings or uninstall/reinstall the affected app if the log shows a missing permission that is not visible in settings shortly before a crash.

I think all my builds are more battery hungry than cm13 was.
[Nexus 7 Android Development] ramblingPrankster:
Ok, so I upgraded from 20170108 to 20170122, and now about a third of my icons are round, and about half of those are just the old icons with round white borders around them. Is there any way to fix this, because it looks horrible.
[Nexus 7 Android Development] Charles IV:
It's imitating the google pixel. To change the icons: install an icon pack, revert to an older version, or edit the source code and build it yourself.
[Nexus 7 Android Development] dlfuller:
Consistent App Stops

Outstanding! Thanks for your efforts [MENTION=3729448]aaopt[/MENTION].

You've brought new life to my old Nexus 7 2012 grouper after I had tried several custom ROMs with poor results! I simply followed your straightforward install instructions and did a complete and clean install.

It is now responsive and most apps seem to consistently work great. Although some stop right after launch, typically when tapping for some action. Un-install, re-install the app, reboot, repeat the same steps, and the app stops in the same way. The key characteristic is consistency. A pattern of the same app crashing at the same point.

Is a simple fix possible? Random crashes when stretching boundaries are one thing, but consistent failures rendering apps unusable are another.
[Nexus 7 Android Development] abhifx:
install nova launcher and get an icon pack.
[Nexus 7 Android Development] Charles IV:
I get this as well, and i imagine it's because 7.1 wasn't designed for the nexus 7. I found the app crashed when certain tasks were preformed, like performing a certain function in a certain app. I got this with ROM toolbox pro. I then opened it in ROM toolbox lite, and it worked, I then opened it in ROM toolbox pro again, and it worked. Very confusing. Run a logcat, I'm not sure what will be done with it.
[Nexus 7 Android Development] aaopt:
Based on some discussion in [MENTION=2188693]AndDiSa[/MENTION]'s AOSP7 thread, it might be related to libsensors.so. If it is the same issue they discussed, it might help to wait a bit after launching the app for the contents of the screen to settle. If after waiting you can pick the same thing without crashing, it is the same issue. Some kind of code fix is needed but from what I understand, it's complicated.

If that doesn't help, you can try to pastebin a logcat collected just after an app crashes so we can see what we are up against. No guarantees but sometimes something will jump out which suggests a workaround or a fix.
