Hi there,

Just for clarification regarding my problem with Chromecast, I tried with another device (Grouper) where I installed this ROM and it worked. I suspect my problem can be related with some permission or whatever. When AndDiSa releases the next build I will install it from scratch and hopefully the cast will work in my Tilapia.

Cheers
[Nexus 7 Android Development] kozmo2k4:
Just wanted to chime in and say THANKS to the developers of this ROM.

The Grouper has got a new lease on life!

I just can't believe I had waited this long to flash it.

Keep up the good work fellas.

Very stable, still some DRM issue

Hi,

Thanks for the great work, the ROM is very stable and performances are impressive considering the age of the device. I still have problems with DRM though, i.e. with the 6.x Pure Nexus I can get Netflix Download, as well as other apps working perfectly (not the case on 7.x which is the reason I reverted for now) I tried the Lineage and other build, always the same problem. Do others still have the same issue (just making sure it is not my device), I saw there was a bug about DRM initialisation, any idea if that could be fixed in the future?

[Nexus 7 Android Development] AndDiSa:
[MENTION=8034485]0rb[/MENTION] DRM issues will be fixed with the next release which will be released as soon as I've integrated the February security fixes.
[Nexus 7 Android Development] zapb42:
I dug around and couldn't find much, sorry if this is obvious, but I followed the directions in the OP, flashing from TWRP and using the dynamic gapps package listed there, hovever Google Play Services keeps stopping. I'm coming from a Marshmallow PureNexus ROM so I'm wiping everything before flashing. I also tried just flashing the ROM, booting into system and letting it sit for a while, then going back to recovery and flashing Gapps, but same thing. It's been quite a while since I've flashed a ROM, am I missing something obvious or doing something wrong? Any advice much appreciated.
[Nexus 7 Android Development] AndDiSa:
You need to flash gapps *before* you boot into the system otherwise the permissions of the gapps are not set correctly and you need to correct them manually. Go to apps / security and grant all permissions to the Google apps which they are asking for ... or start from the beginning, I.e. wipe and flash again.
[Nexus 7 Android Development] zapb42:
Thank you, I think I got it going. I tried rebooting into recovery before installing Gapps and then rebooted to system, that seems to have worked and gave me the Google set up wizard to restore apps and settings.

Thanks again!

hi [MENTION=2188693]AndDiSa[/MENTION]

how much time we need to wait for your new build with febr patch??? thank's for answer and thank you for build this rom ^_^
[Nexus 7 Android Development] Ahkah:
The more you urge him (or her/it/*) the longer it will take. :)
[Nexus 7 Android Development] AndDiSa:
[MENTION=1958679]pirigu[/MENTION] for sure less then any one of the device distributors ... ;)

Scherzi a parte ... As Google just pushed the changes to the repos I need to sync, to build, to do at least a short test and to upload and as I do not have a very fast upload line ... :(

I hope it will be available tomorrow, but without any guarantee.
[Nexus 7 Android Development] aaopt:

Why is this rom so fast???!!! It looks like the hardware is much new!

I tried the lieageOS and this, and I let it so. :)
[Nexus 7 Android Development] Ronald_K:
Following your installation instructions and using the WUG toolkit, it was no problem to install your latest release. It works like a charm. I am so happy to run latest Android on my beloved Nexus7. Thank you very, very much for your good work!
[Nexus 7 Android Development] AndDiSa:
7.1.1_r20 release is available

I've just uploaded a new release of the ROM, based on Android 7.1.1_r20, i.e. February 2017 security fixes are applied.

Additionally there are some other modifications applied to the sources:

ota update script modified so that /system is formatted before applying a FULL-OTA image, so a /system wipe is no longer needed

DRM issues (hopefully) fixed

some changes in the kernel (please refer to the changelog on Github to see the in detail), the most important ones are

compiler change from gcc-4.9 back to gcc-4.8

usb hostmode charging

several additional patches and optimizations

I've successfully flashed the latest ota, gapps and supersu in one run without rebooting in between. The packages can be donwloaded from the OP, or directly from here:

7.1.1 Grouper OTA-Package (Build 20170207) (md5: c764b96174c1c79df27c561bd2e57138)

or

7.1.1 Tilapia OTA-Package (Build 20170207) (md5: 1dfdf38c408014d88e5c480e6f5d828f)

Gapps for 7.1.x (I used Mini_Dynamic_GApps-7.x.x-20170121.zip)
[Nexus 7 Android Development] Ahkah:
As far as I understand this results from the "parrotmod" settings being included in AndiSa's kernel. That's why I think that AndDiSa's Android 7 port is currently without alternative. There might be a version of the "parrotmod script" that is compatible with LineageOs 14, but installing four packets (OS, SU, gapps and parrotmod) had always be an pain in the past, i.e. with Android 6.
[Nexus 7 Android Development] pirigu:
thank you so much andsisa! i will try this and report problems if i found one!

just a little question...i have install the january version of this rom...can i just flash this update without doing wipe? or is better do a factory reset or hard reset? thank you for answer :)
[Nexus 7 Android Development] AndDiSa:
[MENTION=1958679]pirigu[/MENTION] no need to do a factory reset, probably I would wipe dalvik/cache.
[Nexus 7 Android Development] pirigu:
thank you once again! ^_^
[Nexus 7 Android Development] abhifx:
that's one big change (usb host mode charge) which i guess every enthusiast was waiting for. thumbs up!
[Nexus 7 Android Development] xplong666:
Installed all files (Tilapia & Dynamic GApps) using Nexus Root Toolkit v2.1.9 with default values without problems.

I will add comments if I find errors, but first impression is quite good.

Many thanks!

[Nexus 7 Android Development] pirigu:
the rom is really smooth and good! the very first problem is the wifi connection! sometimes crash and have many trouble to recconect! after 1 minute back to go! but i think this problem will live for ever cuz of drivers but this is my opinion :) by the way nice job really great rom! keep up your work dude :)
[Nexus 7 Android Development] AndDiSa:
If you have crashes, could you please provide with a logcat? I didn't had a crash for weeks now and also WiFi is working very stable for me. From that point of view every log file which helps to locate the problems are very appreciated ...

[Nexus 7 Android Development] paasoares:
Thanks AndDiSa for this new release.

Just a question :

till now, for installing new versions of this rom, i always did format system/data/cache & dalvik and then install rom/gapps/su.

With this new version is it possible to just clean cache & dalvik and then install rom/gapps/su ?
[Nexus 7 Android Development] AndDiSa:
[MENTION=342699]paasoares[/MENTION] Yes, if you are already on a previous version, otherwise you should do a factory reset / full wipe.

Can confirm, DRM finally working and Netflix offers now Downloads. Good job, riesigen Dank!

(Update went fine without system wipe and without recovery reboot before GApps.)

DRM is working

I confirm that DRM is working on my side, Netflix Download works perfectly, as well as Amazon and the french myCanal app I mentioned.

I had to do the boot to recovery between the ROM and the GAPPS for GAPPS to work (I use AROMA) and got some slowdown and app closing right after boot, but it has stabilized. Can't believe how usable and smooth Nougat is compared to the last official ROM... makes we want to actually use the device!

Big kudos AndDiSa.
[Nexus 7 Android Development] AdriK:
[MENTION=2188693]AndDiSa[/MENTION]

Previous ROMS I also flashed OpenGapps, like you recommended.

This ROM you are using DynamicGapps again.

Can I dirty flash an older ROM with OpenGapps, with the new ROM and DynamicGapps, or do you expect problems and will I need to do a full system/cache/data wipe?
[Nexus 7 Android Development] AndDiSa:
[MENTION=562996]AdriK[/MENTION] I don't expect problems when you dirty flash. The only issue which might occur: the dynamic gapps to not contain all of the gapps you had installed before. In that case you need to re-install and/or you probably keep some garbage in /data
[Nexus 7 Android Development] kwsam9:
[MENTION=2188693]AndDiSa[/MENTION], I think the link you listed for the SuperSU (2.79 SR3) has problem installing in systemless mode. I tried 4 times, failed and ended up in bootloops. I downloaded v2.79 directly from supersu.com, and it was installed successfully.

The latest build seems to be working quite well so far. Thanks for your hard work and dedication.
[Nexus 7 Android Development] AndDiSa:
[MENTION=7818845]kwsam9[/MENTION] thank you very much, I've changed the URL now. Looks to me as if the attachment in the linked post was changed to the system-mode SuperSU.
[Nexus 7 Android Development] paasoares:
I can confirm that dirty flash is working ok (still need to wipe cache & dalvik after installing SU)

Smooth as silk :)
[Nexus 7 Android Development] thierry+:
Thank You Very Much Indeed!

Hi AndDiSa,

thank you for this ROM it is just simply beautiful to behold in operation and as it is ASOP! This nougat release has given me operational BT v4.0 (BLE) which means i do not have to buy a new tablet..... My "antique" N7...lol... is now working as quickly and as slickly as when i bought it new with ICS or at least it appears so. Was a big fan of your MM release but i have now found something better; thank you for your recommendation.

square app list not working

I noticed that the bottom menu item for the 'BOX' does not work.... and the 'circle' Home soft button does not work - but the 'BACK triangle' does...did I flash something wrong?

Thanks for your help - I have been reading - maybe I'll find it ... :)

--------------------------------------------------------------------------------

Fixed it. I factory reset it and it works.
[Nexus 7 Android Development] pkarza:
No root?

I flashed the rom and then SuperSU, wiped dalvik/cache - and root checker claims no root... any suggestions on what to do?

------------------------------------

wow - rebooted into twrp and reflashed. working fine.
[Nexus 7 Android Development] iamelton:
the roms working fine.. thx OP for the nice work..
[Nexus 7 Android Development] :
Another 'thank you' for me.

I dirty flashed over the previous version, flashed SuperSU 2.79 and open gapps pico and everything went well. I didn't need to restore or re-install my apps. In fact, it couldn't have been easier.

My initial feelings are that this release is both more stable and has better battery life, though obviously that is subjective and could change over time.
[Nexus 7 Android Development] vetzki:
could you add sepolicy patches for phhs superuser and his su binary?
[Nexus 7 Android Development] AndDiSa:
[MENTION=3445844]vetzki[/MENTION] I don't think so, because:

- currently there is no su-binary provided and I do not want to include one in future

- people should be able to decide by their own whether they want to root their device, or not. Especially because there are more and more applications which will not run on rooted devices
[Nexus 7 Android Development] mausbock:
Hi [MENTION=2188693]AndDiSa[/MENTION]

many thanks for this great ROM. I flashed it today after trying some different ones some months before on my tilapia.

But now I have a question: I am not able to edit the quick settings. I tapped on the pencil but I cannot swipe symbols e.g. location from the bottom to the top region. Am I doing something wrong or is it a bug?
[Nexus 7 Android Development] AndDiSa:
[MENTION=6755201]mausbock[/MENTION] Here everything is working like expected. Did you wipe before flashing this ROM?
[Nexus 7 Android Development] psiphi:
No problems flashing. Programs are working as well or better than before.

Plants vs. Zombies 2 is not working correctly. (Did not work in previous versions either) I can hear the sounds but the screen is blank until I Exit out.

I too am having the random network drops. Have just reset the wireless connections and rebooted but did not have the chance to test if this helped.

This is a very impressive Rom... Thanks much...
[Nexus 7 Android Development] uwo83m:
Thank you AnDiSa for your hard work. The Rom ist working very snappy but i'm having problems with the brightness control in the notification bar. When i slide to the left the Display gets at 20% fully off. Do you have that issue too?
[Nexus 7 Android Development] tpuserhp:
Hi [MENTION=2188693]AndDiSa[/MENTION], I am also having this issue. I even wiped system, data, and caches. I then installed rom, rebooted to recovery, installed gapps, supersu and v4a. But I still cannot edit the quick settings as above. Its not a big deal for me. Just odd.
[Nexus 7 Android Development] tpuserhp:
Looking at this further, I found out that on that edit quick settings screen, I have to position the touch at the right place of the icon and press on the icon a bit longer before I can drag the icon around. It seems the touch was not that sensitive on that menu. Or my screen is really dirty. Anyway, it's no longer an issue for me.
[Nexus 7 Android Development] AndDiSa:
[MENTION=5333182]tpuserhp[/MENTION] [MENTION=6755201]mausbock[/MENTION] I think it has something to do with background processes, especially optimization by art. After a new installation apps are processed in the background and compiled into binary code. If there is too few memory available unused processes are even stopped and swapped out of memory. This may have influence on the interaction speed, too. I noticed a slow reaction on my tablet, too, but after a short time everything was going on as expected.
[Nexus 7 Android Development] tomtom_38:
Can I install supersu later.

from the play store?

I have experiances with Nexus root toolkit.

can I use this to flash the rom?

can I install it without twrp?

I mean with adb tools only
[Nexus 7 Android Development] AndDiSa:
[MENTION=6811049]tomtom_38[/MENTION] some people are reporting that flashing by using adb sideload is working, too, but I never used it. You can try to install it with a toolkit, but then you are on your own.

SuperSU from the play store will not work as it does not install systemless (as far as I know) and this is a precondition for installing it on this ROM.
[Nexus 7 Android Development] mausbock:
[MENTION=2188693]AndDiSa[/MENTION]

Oh, sorry, it was my fault. I was simply swyping the symbols in quick settings edit mode. But it is required to tap and hold the symbol and then swype it to the right position.

So all is working perfectly with Your ROM. It is butter smooth and now rooting is not required for me anymore.

Many thanks for Your work!
[Nexus 7 Android Development] pehlm:
@AndDiSa, can I update the systemless superSU binary through eventual updates pushed at play store or must I always flash it in TWRP? I have installed superSU Pro from play store on this ROM, after the systemless flash of superSU that you suggest at installtime, and it's working as expected after that.
[Nexus 7 Android Development] AndDiSa:
[MENTION=7682126]pehlm[/MENTION] superSU pro does not install SuperSU, but modifies only the interface of the SuperSU app (as far as I understood). From that point of view it should be fine using it if you want to do so.
[Nexus 7 Android Development] pehlm:
Yes, thank you, I understand that. But it is possible to update the superSU binary (if new versions) through Play Store, I've done it before on other devices. Is that doable in systemless mode? Or must I flash all new version updates from TWRP?
[Nexus 7 Android Development] AndDiSa:
As long as the binary is installed in the correct place there should not be any problem but I've never tried it. I suppose it will work, but without any guarantee ... ;)
[Nexus 7 Android Development] pehlm:

Swipe not working

Hi,

I have just flashed the ROM a few hours ago. It works butter smooth. Thanks a lot for this.

However, I see that swipe is not working on the keyboard. Is this a known problem? If not any solution?

Apart from that, I do notice somewhat frequent app closes.

Thanks,

Clean flash with Gapps on OP. "Google play services" crashing every time I start using Google Play. Its very unstable. Pop-up appears with options "close app" and "don't restart until next reboot".

I managed to install some apps but it's annoying.

Any Idea?

The rest is very smooth. Never seen my N7 so smooth and responsive.

Thanks for your work [MENTION=2188693]AndDiSa[/MENTION]
[Nexus 7 Android Development] tomtom_38:
I had the same issue. My mistake was to forgot to wipe all thinks execpt system of course.

then i reflash all things and it works.

Go to wipe and advance and choose the right things
[Nexus 7 Android Development] AndDiSa:
[MENTION=4297469]hormosapiens[/MENTION] [MENTION=6811049]tomtom_38[/MENTION] when installing the ROM do a full wipe if you are not already on AOSP 7.x,. Then install the ota and install the gapps together, do *not* boot into system because otherwise you will get permission problems and force closes of the gapps unless you adjust the permissions manually. Do *not* restore apps /settings via Titanium this will lead to issues, too.
[Nexus 7 Android Development] pehlm:
Thank you for the smooth, very good ROM! But I must give some thoughts about the install of the ROM. There are some uncertainty howto flash this ROM. My experience both on this ROM-version and earlier version is that the best way to install the ROM is to boot in between installing ROM and Gapps + superSU, I use Gapps Pico version. If don't doing so there is many problems with Gapps FC after booting the system. The last time I upgraded the ROM, to the last 20170207-version, I was doing a clean flash, full wipe (system, data, cache and dalvik) and I was booting the system up between flashing ROM and Gapps and it was working as it should after that, like on the 20170105-version, not doing so give problems. So it is some confusing points on this to flash the ROM in the right way. I should say that the recommended way is to do a clean flash of each new version (wipe system, data, cache, dalvik), flash the ROM then fully loading the system and then booting to recovery again flashing Gapps and superSU, restoring user apps with Titanium (see below), and the system is very, very stable I can say after that.

I can also say that restoring *user*-apps from Titanium, is a way that's working too to quickly have all apps back again after flashing a new version of the ROM, but of course you can not restore old systemdata to it and if you aren't on the AOSP 7.x, and flashing this ROM possibly that is not going to work neither (without bugs and FC:s).

I am a little confused. But thank you for a very good stable ROM. Only giving you some of my own reflections.

[MENTION=2188693]AndDiSa[/MENTION] I have been using ur MM Rom i.e. aosp_grouper-userdebug 6.0.1 MTC19Z eng.ds.20160109.165025 test-keys.

It works like a dream.

1st a quick note: My USB is broken. I have a nexus dock to charge my nexus7, but no way I can connect it to PC to use ADB incase something goes wrong.

So my question.

What do I need to do to get this 7.1.1 rom on my nexus 7.

Do i dirty flash? Do I need to do factory reset? Is their anything particular i need to be careful about while I flash this?

It is just awesome how much ppl like you keep giving life to such old devices.

Kudos.

Thanks in advance.
[Nexus 7 Android Development] vetzki:
ok, thx.

I made my own boot image with phhs su binary and sepolicy patches (and your device tree + kernel).

first I had this problem:

[IMG="mmap error"]https://picload.org/image/ropacili/screenshot_20170212_130149-1.png[/IMG]

I only could fix it by changing init.cpp.

(kernel is missing:

/*

* Set /proc/sys/vm/mmap_rnd_bits and potentially

* /proc/sys/vm/mmap_rnd_compat_bits to the maximum supported values.

* Returns -1 if unable to set these to an acceptable value. Apply

* upstream patch-sets https://lkml.org/lkml/2015/12/21/337 and

* https://lkml.org/lkml/2016/2/4/831 to enable this.

*/

Flashed the latest build with clean flash, but can't keep the brightness to a min value. Why so? Or any tips to overcome that issue?
[Nexus 7 Android Development] psiphi:
As a followup, a couple reboots do seem to solve network drops issue. I guess we just need to do this when we do a flash update, not just a fresh install.
