Been building roms from source for a while now. CyanogenMod, Lineage, Sailfish OS, and soon, something else I am sure.
[Nexus 7 General] CamoGeko:
Currently on crDroid 7.1.2 but been having a lot of weird things going on with it lately - SystemUI crashing, screenflicker, black screen, tablet freezing etc...

So I'm looking for flash something else today, might go back to SlimKat 4.4.4 or something.
[Nexus 7 General] Cocalarix:
I was also having the same problems with crDroid. I eventually switched to nAOSProm and I have to say, it's a lot more stable. Rarely anything crashes, although sometimes the tablet slows down for no reason, which I end up fixing it with a reboot, since it's not very long on this ROM.

So far, it's probably the most balanced of new and performance. In my experience from what I've tried:

SlimKat 4.4.4 - best performance, dev is active (security patches from 2018), less features, compatibility issues with some apps

Pure Nexus 6.0.1 (basically AOSP) - the most stable ROM out there, but not the best performance, a few less features than Nougat

nAOSProm 7.1.1 - imo best balance between features and performance, the tablet does slow down occassionaly, and the dev isn't updating it anymore (build is from October 2017)

A few more tips for anyone interested:

I've been pairing it with Xposed + Prevent Running module, which stops pretty much anything from launching in the background. It's aggressive, so don't let it stop stuff like Gmail, Messenger, if you use them.

Also, don't use the main Google app, it's way too much for our poor Nexus 7. I recommend switching to Google Go, and honestly any other Lite version you can find (Twitter, Messenger, etc).

And don't forget to turn off animations in the Developer settings.

My Nexus 7 had the same issues you describe and it was a loose battery connection, have you opened up the back to check yours? I don't know how or why it caused these problems but I secured it with a tiny bit of tape and it's been perfect ever since.
[Nexus 7 General] saraomani:
I installed it yesterday on my N7 and it has put a new life in the old device.

I think I am going to settle on AndDiSa's rom till the last days of N7 now.
[Nexus 7 General] CamoGeko:
Ugh nah not really in the mood to open it, doesnt happen anymore tbh. My Nexus 7 did refuse to charge on crDroid once or twice but its been alright since.

I am now running the SlimKat 4.4.4. ROM and having no issues.

I just wish this tablet had QuickCharge, would be just perfect.
[Nexus 7 General] Letitride:
Been neglecting my old N7 2012 WiFi tablet for a while (32GB) and recently DIY battery replacement, put new life into it - now holding a solid & full charge (AcuBattery life @ 102% of capacity) even when powered off for several days.

Pretty much tried out a variety of recent custom Roms, was on crDroid's recent build, began to feel a bit sluggish & screen becoming unresponsive, Now, I am using the latest NZH54D Android 7.1.2 AOSP Grouper - it seemed to be more responsive & less prone to screen freeze, etc.

With newer devices to play with, I am keeping this around for light web browsing, checking emails, youtube, and mp4 playback (MX Player and VLP Player) ... although I have most compatible Apps installed, as a backup in case the Huawei & Nexus smartphones run out of battery on the go.

With a 7" screen, I also use it as a mini HD monitor for a remote home security camera app. If and when the N7 finally give up and stop running, for whatever reasons, not sure if I am going to replace it - or just "activate" one of the 5.5" to 6" inactive smartphone.

It's resale value on eBay & Swappa is very low and doesn't make sense to put it on the auction block, after subtracting shipping costs, eBay & Paypal fees and other related expenses ... thus, I might as well keep it around & put it to good use. Maybe it will last another 3 to 5 years with light use.
[Nexus 7 General] Edmontonchef:
I have a 2012 32gb Tilapia. When I bought this tablet it had already been updated to lollipop.

After flashing every Tilapia/Grouper ROM I could find there were always either performance or charging issues. The only custom ROM that I kept going back to was slimkat 9.1

Today I fastboot flashed the last KitKat 4.4.4 factory images and holy hell this thing is fast!
[Nexus 7 General] MrFTAMan:
I am planning to use my Nexus 7 (2012) grouper for my head unit in my Ford F-150.

My tablet is unlocked and rooted, Android version 7.1.2 (LineageOS version 14.1-20171122_224807-UNOFFICIAL-aaopt-grouper), and kernel version 3.1.10-nougat-g72fc28a. It is the WIFI model.

I’ve read about the Timur ROM that most people used for their Android but I see that since 2014 it was discontinued. Is there a ROM that will work for me?

Would I be able to use the Nougat 7.1.2?

Any suggestions will help me.

[Nexus 7 General] Johan132:
I was gifted a Nexus 7 (2012) sometime ago, and with the [MENTION=2188693]AndDiSa[/MENTION] maintained AOSP 7.1.2 ROM, it is very usable! Maybe not fast powerful enough as a main device, but great as a "media station". I was pleasantly surprised to see that Netflix runs very smoothly (actually I was surprised to see it running at all).

It's great that developers still put efforts in those "old" devices; saves them from the scrap heap :)
[Nexus 7 General] grotesque02:
Maybe I'm a little OT.

Every rom for me have SOD (sleep of death) except unofficial lineage 14.1, but only first time I flashed.

In a new flash, same rom same gapps come back the SOD...

How I have to do?
[Nexus 7 General] AndDiSa:
Did you try to keep WiFi on when sleeping? I suppose it's related to deep sleep mode and there are some devices which have issues when waking up from deep sleep mode. Keeping WiFi on might help to prevent this.
[Nexus 7 General] grotesque02:
This don't solve my problem...

Maybe I open a new thread?

My Nexus 7 2012 version is nearly as new. I did only OTa uograde... but from last upgrade i got, it become useless tablet.

Incredible slow. 2 minutes to get screen, than need many minutes to wish to use some app.

It has much giga free, few apps as Pocket, Aliexpress, udemy , youtube and somethings so small... but it's really slow slow and sometimes need close.

What Rom do u suggest actually?

I has Android 5.1.1

Kernel 3.1.10

Nexus7 Multirom

I use my Nexus (grouper) for playing with different OS'es, like Sailfish, Ubuntu, WebOS, Plasma ... . Or I use it for travel by air, because of the small size and weight.

I still need an plasma active mrom, is here anyone who can share this ?

best regards
[Nexus 7 General] daiash:
Which OS do you find is quickest for daily use?

And how can I install ubuntu or something like that on it?
[Nexus 7 General] commzod:
So I just resurrected my Nexus 7. I wanted something to read books and comics and possibly the occasional video. Nothing else! Since even trying to type on it was a nightmare. Went through and disabled literally every single app that I could. Now I just have Play Books, Play Movies, Play Store, Youtube, and ComicRack installed... THAT'S IT!!!! I disabled basically any system app that it would let me. Now runs fairly smooth for my purposes and with the wifi and bluetooth off (everything is stored locally) the battery life is approximately 9ish hours of screen on time. I'm tempted to pick up the Nexus 7 2013 just for the resolution bump if I keep reading comics on it, but will have to prove to myself it's even worth it. Other 7 inch tablets today dont seem like that big of a jump up from that unless someone has some suggestions.
[Nexus 7 General] greeneyez15o:
U can get and Amazon fire for $40 , almost identical specs to Nexus 7
[Nexus 7 General] rahimali:
It works perfectly fine with a KitKat ROM on it. Try the unofficial SlimKat 9.1 ROM which is what I'm using. Anything over KitKat and it starts to lag badly.
[Nexus 7 General] CamoGeko:
Thats incorrect.

I have been running an LOS ROM released last year and its been totally fine. Nothing bad ever happens that a restart cannot fix.

Also, this AOSP ROM is almost the only ROM thats being updated right now with the latest security patches... I highly suggest you give it a try if you think you can't run anything above KitKat:

https://xdaforums.com/nexus-7/development/rom-android-7-aosp-grouper-t3467514

Latest October patch is out and its been updated recently! :good:
[Nexus 7 General] drakenabarion:
I dig it out occasionally, update and etc.

The latest idea is for watching TV (Netflix, Plex and StingTV - a local streaming service with live TV and vod).

Live TV stream can be a little laggy. Vod and Netflix is OK.

Tried to install a browser and they all make the device unresponsive.

Blokada makes the device unresponsive.

So literally need to disable almost all unused apps. I don't even have calender or Gmail installed.
[Nexus 7 General] Cydras:
I'm running good on my taliper the NZH54D AOSP Rom with Andoird 7.1 and f2fs on data and cache.

I'm using my Nexus 7 as Car Dashboard with AutoMate App. Working very well :)

If we could overclock 7.1 a little bit it where awesome.

Can anyone recommend a good aftermarket battery for our tablet? I still have the original battery from 2012 installed, it drains more than it charges :(

1,5A in my car.
[Nexus 7 General] gc2712:
I purchased one some time ago and it works fine, but not available from that seller now. Just did a Google search on "C11-ME370T" and found heaps. Good luck with that. Fitting it was fairly easy. Just watched videos and iFixit.
[Nexus 7 General] drakenabarion:
I am thinking that mine is just wearing out. It hangs more than I would like in things such as play store.

What would be a good suggestion for a newer device with similar form factor? Given that I don't really want to change from an nexus 7, like the ASOP experience without preloaded apps, etc.
[Nexus 7 General] davidjormi:
After software update the touch screen has been stopped working Now I am using it with a mouse through OTG

Could be possible due to the software or is just a coincidence?

Which replacement touchscreen do you recomend?

Thanks¡
[Nexus 7 General] jago25_98:
drakenabarion: Certainly disabling GApps will give a big performance boost to everyone here but of course you lose a lot of functionality. You might be able to switch to F-Droid and Aurura store and do what you need to do.

I've literally just bought a Grouper in Nov 2019 and a 12" extremely cheap Chinese tablet to compare. The Chinese tablet can't run GApps so I want to run GApps on the Nexus Grouper as a test. Unfortunately I've now found that I need to repartition to make space for GApps and I'm spooked by that.

I'm hoping going back down to 7.1 will help this. I'm going to install this as it's the only thing left updated:

https://xdaforums.com/nexus-7/development/rom-android-7-aosp-grouper-t3467514

By the way, there's also the FSFS filesystem to try, which is suppose to be faster. I'm going to give that a go too.

edit:

I've gone back down to Android 5.1.1 and the app I need to run crashes during certain operations! I'm not sure if it's worth the risk of repartitioning to upgrade or whether ooting could help investigate further in some way:

----

I just need to run a single app on my Nexus called Word Wizard. I bought the tablet just for that because it's the cheapest thing that can run Google Services.

The Nexus 7 2012 (Grouper) has:

950mb RAM available

452-520mb taked up with OS related services needed to run the app.

Android 5.1.1 (without the memory leak I think)

ARM not arm64 like my phones that can run the app without crashing

The app:

- uses 13mb memory

- data size = 51mb

- needs Google Play services for the paid part I need

- runs but crashes at a part in the menu that, I think, requests filesystem access or maybe requires slightly more memory.

- worked fine on Android 8,9,10 on my other phone(s)

Upgrading to Android 7 is risky and difficult. I'd need to repartition to keep GApps. Does it even help? ( https://xdaforums.com/nexus-7/development/rom-android-7-aosp-grouper-t3467514/page392 )

Would rooting allow me to investigate this further?

Hi! My nexus 7 buttons are broken and sadly my tab is struck on boot logo.. any Idea how I can force into boot loader mode with out buttons ?
[Nexus 7 General] sara.ramli:
Am not sure you say "similar form factor" because you have it installed in your car or for some other reason.

Anyway the MiPad4 is the closest in terms of similar dimensions with a bonus of 8" screen to boot.

I just happened to replace the Nexus 7 in my car with this tab.
[Nexus 7 General] Cydras:
Hi,

I use also a Nexus 7 in my car.

I am thinking to buy a MiPad4. So you know if the MiPad 4 Supports USB OTG with Charging?

How do you Output Sound in your car?
[Nexus 7 General] sara.ramli:
Yes it does. I am using the HavocOS 2.8 available in XDA.

Using a type-c powered hub and have connected 3 USB devices - a USB DAC, a SDR FM Tuner, an easycap device for reverse cam. Will shortly be posting a video of the working setup.
[Nexus 7 General] Cydras:
This sounds awesome! Sounds that i must buy the MiPad 4 :D

I want to use the iBasso DC01 USB C DAC with Spotify.

What for a Car Dashboard are u using? I am using AutoMate.

Thank you very much for your information! Can you please post your using USB C Hub?
[Nexus 7 General] sara.ramli:
Sure good luck with your upgrade. Mine is a Behringer. If you haven't already tried the USB audio player, you should. The proprietary driver they use takes output quality to a different level, compared to the stock android driver.

Built a dashboard to my liking using KLWP and Tasker.

This is the hub:

https://pibox.in/product/usb-hubs/

Given that getting the right hub is important to make this work, glad that the first hub I tried worked. Was planning to order a spare as backup, but it has gone out of stock :(

Has written to the seller asking if and when it'll be back in stock.

I'll see if I can post the hub's controller vendor and model information from the kernel logs, after going home. Can serve as a reference for comparison.
[Nexus 7 General] TNSMANI:
Who said that unless you repartition you can't run Android 7? I am using THIS ROM on my tab and it is running very well. No repartitioning required. Read the instructions carefully and use only the linked Gapps. Anything else needed can be downloaded from Play Store and installed as private app.

EDIT: Just noticed that it is the same ROM you are referring to. Go ahead. No repartitioning.

Great thread!

I use my Nexus 7 (2012) Grouper time to time. Mainly for just music, sometimes gba emulator (DS works but can slow down) or tweaking inside LinuxDeploy. I am running a 7.1.1 Lineage OS, SuperSu (Systemless) and using fstrim for trimming, though I might need to change the setup, any recommended roms? I would love to try Maru OS but thats only on the 2013 models. I am hoping to either turn my nexus 7 into a youtube/music/emulators/linux machine in my car with AA mirror (if possible) or just update it and use it as a regular beside tablet. IDK.

Use as Car Play/AA headunit

I was also running Andisa's 7.1 ROM for a time on my 2012 N7. But with 3 or 4 other tablets about (upgraded a few times since owning the N7) I am now repurposing to go in a car as a head unit. Found a dongle on Amazon that when used with a usb otg y cable, will bring up Apple car play or Android Auto as if it is a proper head unit. So downloaded a super old ROM (4.1 I think) that was built for this purpose, as has a super deep sleep mode when power is switched off, and proper USB adapter recognition. Works like a dream. Just need to pursuade my GF to let me put it in her car now, once I whip up a sensible bracket for it. I did plan to install and completely replace head unit wiring to fully install, but will likely install with current Bluetooth head unit, to save having to wire in a volume control etc.
[Nexus 7 General] CamoGeko:
Thats a very good ROM indeed, used it for a while myself.

However, for stability reasons I flashed back to an LOS build from last year and I found it doesnt slow down as much.

I come from a Z2 on rooted 6.0.1. I'm currently running 7.1.1 on my Z5P and I'd like to root it. It seems like the current method requires an unlocked bootloader but I'm not quite inclined to do so, unless I'm assured I wont lose much or there's a way to backup my TA before rooting the thing.

Thanks in advance for any information you can share with us. I'll keep searching the forums for more information on the subject.
