For all of you who have issues that Google Play Services is force closing: Go to settings - Apps - Google Play Services and give it all permissions it needs. That will fix the problem

Backup/Restore "backing up to debug-only private cache issue on Backup settings

if in backup restore you have this to fix and re enable your google account fix it whit usb debuging enabled and adb on pc with phone connected run

adb shell bmgr transport com.google.android.backup/.BackupTransportService

wait for confiramtion ,confirm it and reboot .IF works you will be able to set your goggle account for backup and restore data on cloud
[Nexus 7 Original Development] frantisek.nesveda:
If you installed gapps at the same time as the ROM and you want to set up your Google account in the initial setup wizard, you can open settings even during that setup wizard over adb:

Connect your tablet over USB to your computer

In command line run

adb shell am start -S com.android.settings/.Settings

This will open Settings on the tablet.

Go to Apps -> Google Play Services and turn on all the permissions

Press back until you're in the Setup Wizard again
[Nexus 7 Original Development] abhifx:
seems more like you tried formatting cache using stock recovery.

You will have to flash TWRP through fastboot.

Then best is wipe everything (i assume /data is most probably already wiped too) and install from scratch.

The WeTransfer version works perfectly. Just installing it again now with F2FS and I'll report back.

after installing gapps pico 7.0...got fc msg for google play services every 5 sec which makes it annoying to use
[Nexus 7 Original Development] H00pyFr00d:
Did you try the solution posted the previous page?

For all of you who have issues that Google Play Services is force closing: Go to settings - Apps - Google Play Services and give it all permissions it needs. That will fix the problem
[Nexus 7 Original Development] abhifx:
actually everything is fine on my tablet, i was explaining to some other users. thanks anyway.
[Nexus 7 Original Development] vocoderism:
which build you are using actually?
[Nexus 7 Original Development] H00pyFr00d:
Ah. No, I have the same problem. FC every few seconds even with all the permissions enabled.
[Nexus 7 Original Development] armada786:
This definitely isn't bad for a at all for a first build of N. Only problem I really saw was that the recents apps cards look a bit weird. Almost as if their drop shadow is rendering above the card and clipping what is beneath. Also the header bar in setting looks a bit misaligned for some reason.

Outside of that I didn't really stay on the ROM very long. For some reason I couldn't seem to get parrotmod working (according to read_ahead_kb containing "2048"). I might go back later and try to get parrotmod working again because I think N will work quite well with it.
[Nexus 7 Original Development] NeoPreacher:
Had the same issue. Use 'adb reboot bootloader' to get back to normal bootloader and then flash recovery using the fastboot command. Thank ziyan if it helps you too.
[Nexus 7 Original Development] Ziyan:
We're trying to pretty much remove the need for parrot mod. :)
[Nexus 7 Original Development] frantisek.nesveda:
Would it be possible to include this patch so that the core Google apps are granted the needed permissions by default and Google Play Services don't crash on first setup with gapps? Thanks :)
[Nexus 7 Original Development] Sanitch:
Yes, it works. I have found this solutions on 4pda.ru forum, but hadn't time to tell there about. Thanks
[Nexus 7 Original Development] supertiger1234:
what GApps are you using? try Open GApps pico arm 7.0
[Nexus 7 Original Development] DIXES:
Is this normal? Both of AOSP-6.0 and CM-13.0 have no NFC feature in settings.

Thanks.

EDITED: I've found NFC feature in AOSP-7.0, thanks.

After flashing the OP recovery img, when I try to boot in recovery a black screen appears for a few seconds, and then android boot normally, I'm currently on pure nexus rom (6.0.1) with kernel 3.1.

EDIT:I return the normal twrp again to extract a kmsg, but i don't know if this helps

[Nexus 7 Original Development] gusto5:
How do I determine this?

Most of my problems go away if I do one of those "power down, connect to computer and boot" but no variation of twrp recovery or ext4/f2fs allows me to flash the 7.0 rom (both the initial and the subsequently posted one). It starts the patching unconditionally process and lags itself into death :D
[Nexus 7 Original Development] biondi53:
sorry but i don't know what is that

Is anyone else having problems with slow charging on Nougat? My Tablet charges extreeeemley slow and when I use it while charging, it even discharges. I saw some users on the Nexus 5 Forum reporting the same problem, so maybe it is some kind of AOSP problem?

@up I have this issue also on cm13 from this thread...
[Nexus 7 Original Development] Ammar_Hamdan:
Flashed this build with gapps pico.. tablet boots fine.. then wanted to install supersu in order to restore my apps via titanium backup... now i have bootloop :(

Supported API: 3

E: unknown fs_type "f2fs" for /cache

E: can't mount /cache/recovery/last_local

ps. flashed it yesterday without gapps for couple of minutes then reverted back to PN Rom backup by using TWRP without any problem.

edit: flashed twrp 3.0.2 from fastboot and flashed supersu zip from twrp all working fine :) except "Google Play services keeps stoppping" message popping up.
[Nexus 7 Original Development] zerbey:
AOSP 7 build working fine, just had to fix permissions. Will test more and report any weirdness.
[Nexus 7 Original Development] Mucky2:
Okay, does not work for me.

Tried the TWRP version from the op and the offical one. Getting always an error which says "unknown command [log]" twice.

Also tried the other build, still the same issues. Even tried to change the file format, nothing works. My N7 flash it but keeps booting for hours...

-> Fullwipe

-> Flashing the build, then gapps & su

-> bootloop
[Nexus 7 Original Development] vocoderism:
Bootloop or stuck on logo?which variant you have?

O noticed that you guys put here your 3.1 kmsg/dmesg and all of you have the max77663 pmic, if you guys are stuck on google logo or bootloop on google logo (with recovery in the middle), please flash this kernel image after flashing the aosp 7.0 grouper rom and factory reset:

http://pintux.lx.andrepinela.net/~apinela/boot_3.4_grouper.img

let me know the results.
[Nexus 7 Original Development] Mucky2:
Yes, full wipe. Pushing the rom via adb to my nexus but nope. Did even try the kernel from the post above me lol.
[Nexus 7 Original Development] supertiger1234:
Adb? Did you flash the rom with twrp?
[Nexus 7 Original Development] sheffzor:
do in bootloader/fastboot mode:

fastboot erase userdata

fastboot erase system

fastboot erase cache

Then use the volume keys to select recovery and press power btn to boot into recovery, try to flash the rom.
[Nexus 7 Original Development] Mucky2:
TWRP Fullwipe and then adb push rom.zip /sdcard

[MENTION=4619263]sheffzor[/MENTION] didn't work for me, error while installing: "couldn't mount '/system, /cache and /data' + "E: unknown command" twice and "Updater Process ended with error 7"

I have same issue on my grouper. Its the 32gb variant if that matters. I tried directions in OP to get Aosp going. Flashed the recovery img and it just black screens. Wont boot into twrp. I next tried Vocoderism advice, flashed the alternative build and official twrp latest. Well of course twrp now worked, but when i tried flashing both the OP nougat build and Vocoderism alternative build they both hang on the black screen. Both popped two errors while flashing on both builds. Same error codes that someone mentioned a few pages back.

I even tried flashing back to stock factory just to see if that would cure it but no go. No clue whats up but it refuses to work on my grouper. I tried every trick i know since i been in this scene. I'll come back in a few weeks and see if something changes. Thanks for the hard work thus far though. No creamy nougat for me :/ Amazing anyone cares about this old junker still! :rolleyes:
[Nexus 7 Original Development] toplist:
Has anyone got a working gapps for the build? I tried latest pico and nano from Opengapps. Even after giving permission, play service app constantly closes. Trying to install anything from Play store prompts me to sign into Google Account which I've already done.

I downloaded alternative rom from wetransfer, downloaded twrp-3.0.2 from twrp.me. I did factory reset before installing the rom and data/system format is ext4.

[Nexus 7 Original Development] gorneman:
[MENTION=4619263]sheffzor[/MENTION]. Thanks for your effort, but we have no luck, same black screen.

Steps:

1) flashed aosp 7.0

2) wipe to factory reset

3) flash boot.img (from TWRP).
[Nexus 7 Original Development] adeelraj:
I think our nexus 7 are screwed up by installing a lot of custom roms and kernels,recoveries etc

I think installing factory image via fastboot and then install twrp and flashing nougat will do the trick
[Nexus 7 Original Development] erk1725:
This is where I'm at also except mine keeps rebooting to that screen and I can't get into any other menu. Off or that menu and no adb/fastboot recognition from CPU.....adb reboot bootloader and any fastboot commands I try do absolutely nothing

It did boot into ROM once but without a play store app in app drawer, so I rebooted to try to install them again and ended up rebooting over and over again to that screen. I think it's toast

Steps

Install recovery from downloads for grouper

Reboot

Everything fine

Reboot to new recovery. Made backup

Wipe everything except internal

Flash new aosp grouper, open Gapps 7.0 arm pico

Reboot to ROM

Everything seems OK, no Gapps....or at least no play store app in app drawer

Reboot to recovery to install Gapps

Flash ROM, Gapps

Reboot

Get reboot on above screen over and over
[Nexus 7 Original Development] vocoderism:
new build to test grouper

So i released new build to test bootloop issue and gapps issue

follow these steps

TWRP recovery 3.0.2.0 from twrp.me offical to flash from fastboot

WIPE all in advance format all including system

then go to mount and untap flag on system

The same happened to my tablet I wasn't able to access bootloader, so I used "Nexus Root Toolkit" to flash twrp recovery image and everything went perfectly.

just press Advanced Utilities >> there you'll find fastboot flash >> recovery >> TWRP.

I had trouble flashing any ROM after using the recovery in OP so instead I restored using factory image first before continuing. Put TWRP from website back on and confirm I can flash both vocoderism and androisa's AOSP 6.0 builds. When I attempt to flash ROM from OP or the subsequent one a couple pages ago, the output is this:

Any ideas, and is there a way I can get to that log?
[Nexus 7 Original Development] warriorofice:
I´ve used always TWRP 2.8.7.0
[Nexus 7 Original Development] vocoderism:
Flash is ok it is only warning
[Nexus 7 Original Development] aquavalanche:
flashed fine here, using TWRP from OP, and AOSP 7.0. Supersu install freeze and rebooted the recovery, so I didn't flash supersu yet.

Heavy usage will force reboot the N7, and some freeze can happen while loading heavy app. Aside that, everything worked fine.

Is there anything I can do to help? Keep up the good work mate! :)
[Nexus 7 Original Development] seanp25:
Sounds good, I'll flash later today I think. Did you install any Gapps?
[Nexus 7 Original Development] Nexive:
[MENTION=4831205]vocoderism[/MENTION]

Flashed the ROM, Gapps and SuperSU succesfully using the latest TWRP from the official site.

ROM booted fine and it's a very stable build in this early stage.

What works:

- Wifi

- Bluetooth

- Sound

- Rotation

- Youtube playback

- Split Screen

- Microphone

- NFC

Not tested yet:

- GPS

Minor bugs:

- Graphical bug in recent apps

- When you set battery percentage to show always and reopen the system UI tuner it does back to default (show percentage while charging)

- Some apps freezes and force crashes but not much

- Camera does not work (EDIT: Camera works with Camera M from play store)

- Navbav tuner is hided in system UI tuner

- Night mode is also hided in system UI tuner (But you can enable it by installing Night mode enabler from play store)
[Nexus 7 Original Development] aquavalanche:
Ah sorry, forgot to mention that, I installed open gapps 7.0 Pico variant
[Nexus 7 Original Development] gusto5:
Well, now I know hahaha

I flashed the rom and gapps from your thread on page 51, I can reboot into rom repeatedly without a problem. However, the first time I try to access recovery I get the following error (I assume it's broken recovery):

However, a quick adb reboot into the bootloader to flash the recovery back over fixes this. I've done this three times just to make sure the error wasn't a freak accident. LMK if there is some other scenario you want me to run the tablet through.
[Nexus 7 Original Development] erk1725:
after a long and frustrating period, installed linux and I was able to get adb & fastboot recognized, could boot into bootloader, and was able to fastboot flash twrp.img.

I downloaded and installed all the links from page 51

http://xdaforums.com/showpost.php?p=68542226&postcount=507

and everything flashed fine.....and I didn't lose any data throughout this process. However, occasionally, the screen is black when i go to wake it up, but I can hear the screen lock sound....sometimes if I try to reboot, the boot ani doesn't finish and the screen is just black right from the beginning. I've already wiped all and reflashed according to the post on page 51 with the links and directions. Any other thoughts? It runs pretty well so far.

Thank you guys for all your hard work!

For f2fs use vocoderism build
[Nexus 7 Original Development] erk1725:
So this grouper is actually more my sons than mine....he is almost 8 and plays a lot of games. Well after finally getting this thing to boot up and setup up some stuff for him, I let him use it for a bit yesterday.....about an hour. He played hungry sharks and he likes to ask google now a lot of questions and just look at fish and shark pics....kids stuff. Anyways...the point is, he had this thing on for about an hour without any issues with play store, google now, chrome, hungry sharks....no reboots, no FC, no getting booted out to homescreen unexpectedly, so all is well for him. I was curious tho with all the talk of F2Fs....I used this years back on galaxy nexus and really felt it made a difference in performance and read/write speeds. I am contemplating doing this for him with the next release.....do you guys feel it makes a difference on grouper? Performance.....and memory? This is all done in recovery also....correct? Its been a while since I've switched to F2F and just want to make sure I do it right, if Im going to go that route. I need to make a backup, copying storage off the tablet, switch to F2F in recovery, and then copy back over the rom, gapps and kernel to install....profit?

I think the memory is the biggest issue on it right now. He didn't have any problems, but I know I got booted out to homescreen on more than one occasion setting everything up for him

I did add this line to build.prop

ro.sys.fw.bg_apps_limit=20 Not sure if it makes a difference or not

I did this before I gave it to him after I was dealing with getting booted out of an app to homescreen a few times

EDIT: Forgot I wanted to mention ive noticed in certain apps, like I think kernel adiutor, that I am on bootloader 4.18??? I remember reading that 4.23 is that one to be on, and that it may be hard to locate one that works correctly? Any advice is appreciated

Thank you all for your hard work! I really appreciate it and it is like having a brand new tablet all over again:good:
[Nexus 7 Original Development] KawaiiAurora:
Hmm,

I'd suggest upgrading to bootloader 4.23 and installing TWRP 3.0.2 with Kernel 3.4. CM13 with Kernel 3.4 eliminates most performance issues and you can use ParrotMod. About F2FS, your mileage may vary but I had corruption issues with F2FS that disappeared when I went back to ext4 so be careful if you go that route, with that being said, F2FS is faster :)
[Nexus 7 Original Development] erk1725:
Thank you! My performance is pretty good. I wasnt trying to say anything bad, and I know they arent finished yet, so Im sure things will get improved on as time goes by. I am currently on TWRP 3.0.2 and AOSP 7.0 with kernel 3.4 from [MENTION=4831205]vocoderism[/MENTION] build on page 51. Not sure why im still on bootloader 4.18, but I will keep reading around....I also need to do some reading in the ParrotMod thread, but [MENTION=2633638]Ziyan[/MENTION] posted they are trying to remove the need for Parrotmod

Thanks for the input on F2F....I will keep debating in my head for now! lol:good:
[Nexus 7 Original Development] KawaiiAurora:
I'd suggest using CM13 until a stable version of N is out :) If bootloader 4.18 isn't problematic, don't update it as it's not very important. Also, if you have CM 13 (not sure about Android N) with the 3.4 kernel, avoid ParrotMod as the 3.4 kernel has some optimisations of its own in terms of I/O speed :)
[Nexus 7 Original Development] ruicc:
I was using parrotmod on my previous rom....now, flashing this new rom, i'm on bootloop. Could it be parrotmod? Spme leftover?
[Nexus 7 Original Development] KawaiiAurora:
What did you flash? What were you on before? Did you do a dirty flash by any chance?
