That wasn't so good though. Yes I can feel that the device has getting a bit warmer. Is it possible, do you think, to change these sepolicy settings? If it's possible can you hint about that?

EDIT: But I also now see that the 1300 Mhz use go down by time and the 340 Mhz increase, so I isn't convinced though that Magisk uses the CPU wrongly.

EDIT2: The device isn't, on a closer look, getting any warmer neither in idle state, I think, but I may be wrong.

---------- Post added at 13:20 ---------- Previous post was at 13:17 ----------

Another thing is Performance control app not getting proper root access with Magisk. Is it someone else with that? I'm now using Kernel Adiutor.
[Nexus 7 Android Development] pehlm:
For the Magisk hide Safety Net problem, is there someone who can get Magisk hide to work whatsoever, I was hiding rootcheck app in Magisk manager and rebooted the device, but when I then tried to check root with the app it show that the device was rooted, but it should have showed that it wasn't. On another device this worked as expected, same try. So maybe Magisk hide don't work at all on this device and ROM. Magisk su work but not Magisk hide.
[Nexus 7 Android Development] n3kf:
Another Magisk test. So I installed a root checker app. It works and Magisk asks for root permissions. I then went into Magisk and turned on Magisk hide for the root checker. When I run the root checker, lo and behold, Magisk asks me if I want to give root privileges to it. So it would seem Magisk hide is either not running or is not acting properly.
[Nexus 7 Android Development] pehlm:
No Magisk hide don't work properly, I know, see above.
[Nexus 7 Android Development] n3kf:
Did the same test on my N7 2013 that is running LOS 14.1 with Magisk and the root checker says that root is not available on the device. [MENTION=7682126]pehlm[/MENTION] I had missed your post!

I know MagiskHide can be manually started. Might try that later and check the logs to see if anything interesting shows up.
[Nexus 7 Android Development] pehlm:
I've tried to start it manually through a terminal. But it doesn't do anything for the problem, I think. Hope you make another conclusion. :confused:

Update: I've now started the Magisk hide daemon again using a terminalemulator.

1. run "su"

2. cd /magisk/.core/magiskhide

3. run "./disable"

4. run "./enable"

The daemon stops and starts properly as it should.

Rootcheck, as I set it as hide in Magisk manager should show unrooted but it yet show rooted. Hide is thus not working properly with this ROM. The same rootcheck app works as it should to hide on another of my devices with AEX ROM and Magisk.
[Nexus 7 Android Development] n3kf:
Getting a SIGSEGV in magiskhide on startup of the first app that calls for root that magiskhide tries to hide root from. Same issue with safety net I'll post the appropriate logs over on the Magisk forum. Once the magiskhide daemon faults, it does not hide root from that point forward.

The fault is:

05-17 16:18:30.735 F/libc (12060): Fatal signal 11 (SIGSEGV), code 1, fault addr 0x688080 in tid 12060 (magiskhide)

So in reality since this ROM has had issues with apps dying, this could still be a kernel issue in this ROM that is causing the magiskhide daemon to fault. Not saying it is but could be.
[Nexus 7 Android Development] AndDiSa:
[MENTION=6824216]n3kf[/MENTION] can you provide me with the log, too, so I can try to figure out whether it's a kernel issue?
[Nexus 7 Android Development] KuFeL78:
First of all big thanks for the tilapia rom - it brought back my N7 to live. I can confirm that there is an issue with the charging.

The other thing which is happening is that it is loosing the coverage and it comes back only after reboot. Switching to flight mode and back does not help.

Regards,

Pawel

Camera for Grouper

Can someone confirm if the Camera is working for grouper? I am unable to run any camera app with this ROM.

Other than this, the ROM works really well!!!

I have no problem switching off the Nexus.
[Nexus 7 Android Development] n3kf:
Here you go [MENTION=2188693]AndDiSa[/MENTION]. I tried to free the log before I did this, but still tons of log entries. This one I turned Magiskhide off then on (which does what a disable/enable does via terminal), then ran safety net test. It hung until the segsigv happened. Let me know if I can be of any assistance. I have lots of Linux experience. Guess I should become more active in Android!!

New TWRP version for Grouper - 3.1.1-0. :)
[Nexus 7 Android Development] br3wski3:
I too have had good success with Open Camera! :)
[Nexus 7 Android Development] shaggyskunk:
Yeah it wouldn't download from twrp.me (no sd card message) Downloaded it on another device and uploaded it to Google Drive and downloaded from Drive - lol
[Nexus 7 Android Development] pehlm:
Downloaded and installed it with Official TWRP app, good ;)
[Nexus 7 Android Development] AndDiSa:
Seems as if the adb backup - bug is fixed in twrp-3.1.1-0 ... :)
[Nexus 7 Android Development] ashukla:
Grouper Camera

Nope... none of the camera app suggestions in the posts above work. It's either "device not available" or, "could not connect to the camera, are you sure some other process is not using it?" :crying:.

Just to verify, I reverted back to the latest stock ROM for grouper 5.1.1 (couldn't post the link since I am still a newbie :o) and the camera works just fine...

Seems there is some issue with the Camera in this otherwise lovely :good: ROM.

Please let me know your comments....
[Nexus 7 Android Development] AndDiSa:
[MENTION=3193619]ashukla[/MENTION] Did you give all required permissions to the app? Here Better Camera is working without any issues.

Same error message here with Chrome beta. So I installed Dolphin Browser, image file downloaded fine, had to rename it from .txt to .img though.

I second that.

Didn't try the encryption though

[MENTION=2188693]AndDiSa[/MENTION] [MENTION=8280502]a247[/MENTION] I just want to share that I can reproduce this error consistently on LG-P880 in Lollipop/Marshmallow/Nougat ROMs which share the same grouper blobs. This seems to be the last annoying bug, otherwise the LG-P880 ROMs would be near perfect. And, this only shows up with Google Maps. I can't find any other apps having such error. I would have thought that this may be caused by hacks for LG-P880 to use grouper blobs. Well, now this explains that even Nexus 7 using its pristine blobs seems to have the same issue.

From my analysis, I think it has to do with the dalvik GC sweep, which I guess, mistakenly discarded and freed the SurfaceFlinger layer buffers used for the map. I had somehow observed that if you didn't get a dalvik GC sweep, then the map would stay. This also explains that if you have a very light Android without Google Play Services and Google Search, then it is very hard to hit this issue. However, the microphone inside Google Maps requires Google Search, and Google Search requires Google Play Services. That's why it is almost certain that triggering Google Search within Google Maps will trigger dalvik GC sweep as Maps and Search are 2 notorious memory hogs from GApps.

If you happen to root cause this and found the fix, then please share with the LG-P880 ROM community. We can help to verify the fix.

It is also possible that this may be "free-after-use" bug in Google Maps itself. However, the strange thing is Google Maps does not seem to be aware that it has lost the map layer on display, or it would have reallocated the buffers and refreshed the map layer on display.

Hi [MENTION=2188693]AndDiSa[/MENTION]

Sorry for the late reply,

For the magisk issues you might want to look in the following commit for inspiration ;) : https://review.lineageos.org/#/c/164722/

Of course its for a different device/kernel version, but the change should work here too IMHO, and it's a one liner. :)
[Nexus 7 Android Development] AndDiSa:
[MENTION=4573282]namerke[/MENTION] thank you very much for link, unfortunately this doesn't help with the Magisk issues. I suppose to pass SafetyNet using Magisk wee need to have mount namespaces support within the kernel. Unfortunately full namespace support is available only for kernels >=3.8 and we are on 3.1.x :(

Nevertheless the patch you linked to helps with another issue: we will get rid of all those linker messages like: cannot find ... with use the given path
[Nexus 7 Android Development] breaktheblock:
I have a noob question about TWRP and I cannot seem to find the answer easily on the internet.

If I root my device will TWRP see more files in its File Manager, does it show everything?

TIA
[Nexus 7 Android Development] shaggyskunk:
If you Root your device - You should be able to see everything with Root Explorer (if you have the correct settings) Just as you would with TWRP File Explorer.. AFAIK.

Looking to use this for a dash install

Hey everyone, how does this ROM run multi-window? I'm looking to just connect it to a WiFi hotspot and use it to use spotify, maps, torque pro and maybe youtube occasionally. Will this ROM do fine without lagging horribly? Or should I go to a marshmallow or 4.4 ROM? (since lollipop is a joke)
[Nexus 7 Android Development] paasoares:
WHAT AN ENTRANCE !!!

This is your very first post and goes like : i wanna do this, this and this. Is this rom ok ?

little advice :

1) read the thread

2) try it your self

3) report problems (if any) and raise questions
[Nexus 7 Android Development] tommiy995:
I've been a long time lurker and I read quite a bit of the thread. It's 140 pages. I searched a few things to see if anyone else had done something similar and I didn't see it. So I asked. I'm trying it myself but instead of working out bugs someone else has already worked out, or getting work around for issues that other encountered when trying to do the same thing, I asked. I've been using XDA since I had my HTC One X.

Also, I did #3 and you belittled me lol. But, okay.
[Nexus 7 Android Development] AndDiSa:
Guys ... please calm down! [MENTION=7212284]tommiy995[/MENTION] as devices responsiveness is a very subjective thing and is much depending on the installed / running applications it's very difficult to give answers whether your requirements are beeing fulfilled or not. So it's better to build your own opinion. From that point of view [MENTION=342699]paasoares[/MENTION] is right when he states try it by yourself.

Regarding multi window: really speaking I cannot say as I do not use it ... the screen is already so small. I do not feel comfortable with a splitted sceen.

Possible to dirty flash 7.1.0_r5 over 7.1.0_r4 ?

Thanks
[Nexus 7 Android Development] AndDiSa:
[MENTION=3887645]williamlaw[/MENTION] yes, should be no problem
[Nexus 7 Android Development] AndDiSa:
[MENTION=6076637]239[/MENTION] looks as if android 7.1 does no longer support camera HAL1, so either we need to try to include HAL1 support or to write a HAL3 wrapper ...
[Nexus 7 Android Development] 239:
I see, well it's not a big deal since I used the camera only for setting up 2-step authentication but it's just more convenient that way so I don't think it has high priority.

On my side it's more important that the system works reliably in most cases and doesn't crash too much, right now I'm happy with it (logcat lists some errors, though).
[Nexus 7 Android Development] splintstift:
Nice work, but it´s not possible to mount /system read-write. I need it for a modified hosts. What´s the reason?
[Nexus 7 Android Development] AndDiSa:
Security?!

/system is always mounted ro and you do not have the permission to change that. In addition Google changed / removed the mount command from toybox. You can try to install busybox and check if it's working then. Otherwise the only chance to change the content of /system is in recovery. see here, too
[Nexus 7 Android Development] adstraylight:
Root Explorer works with Busybox on Rails/SuperSU, using this combo I can edit build.prop via RE's built in text editor.
[Nexus 7 Android Development] splintstift:
I did it in recovery. Thanks.
[Nexus 7 Android Development] kwsam9:
I tried but not successful. All the Google apps (manually installed from Play Store previously) such as contacts, calendar, drive, etc. are crashing. Reinstalled all the google apps to get them working again.

Not sure what I did wrong in the first place.
[Nexus 7 Android Development] AndDiSa:
You were on Android 7.1.0_r4 previously and everything was fine? You (re-)flashed Gapps-pico for 7.1.x as described in the OP? And then you had crashing Gapps? Next time, probably you could provide me with a logcat, so I had the chance to have a look into it.
[Nexus 7 Android Development] williamlaw:
Just dirty flashed r5 over r4, Gapps really disappeared. I have to flash it again.
[Nexus 7 Android Development] AndDiSa:
Gapps need to be reflashed each time you are doing an update (there is no backup functionality included), but only those contained within the gapps package, the packages downloaded from the play store should remain.
[Nexus 7 Android Development] RastaFATian:
Hello, I have clean flashed this rom with a bunch of things yesterday.

7.1.0_r5 + opengapps pico 7.1 + parrotmod + super su 2.73-SR3 + Arise Deuteronomy 2.3.3 + Dolby Atmos...

Everything is good, I just have 43 Mb in the root with that installation. But everything seems fine and fluid, I just have FC opening the music application from the rom, but poweramp works fine, and viper is processing!

Thanks a lot for this good rom!

Gps seems to not be working here... :\
[Nexus 7 Android Development] AndDiSa:
[MENTION=6042725]RastaFATian[/MENTION] parrodmod should not be needed because I am using almost the same settings.

Edit: Music APP crashes can be reproduced, I'll have a deeper look at it.

Edit2: Music App is using the flag MODE_WORLD_WRITEABLE /..._READABLE for it's preferences which is deprecated since API-17 and was removed completely in Android N. Now it's crashing with a security exception ...

Edit3: Modified the preferences flag and Music app is no longer crashing ... will be included in the next build
[Nexus 7 Android Development] akashkyh:
Guys just installed 7.1.0_r5...

Its Awesome... brings back my Nexus 7 to life again.... now i can use it for some more time... kudos to the developers...

Will soon make a video....
[Nexus 7 Android Development] wenlock00:
Flashed just 7.1 R5 over 7.1 R4 and lost play services.

Flashed new Pico GAAPS extract for 7.1 to get play services back.

Gmail crashing and generally and all apps very laggy and slow.

Decided to revert back to 7.1 R4 (full restore) for now.
[Nexus 7 Android Development] AndDiSa:
After new installation, let the device settle down a bit. There are several art processes running in background optimizing the memory / compiling applications / etc. After a few minutes everything is working smoothly and app closes are vanishing (as long as you were already on 7.1.x before ...). Coming from 7.0.x at least a cache / dalvik-cache wipe should be applied.
[Nexus 7 Android Development] wenlock00:
1) Backup all your sensitive files (not applications' data as Titanium Backup restores can cause strange reactions on the updated system).

2) Wipe data using TWRP's functionality by going to recovery, wipe option and selecting the option right below (Wipe data), type yes and swipe the bar. Once finished, reboot again into recovery in order to avoid problems during installation.

3) Perform a factory reset as the main wipe screen suggests and after being done all the previous steps, proceed connecting your handset to the PC and transferring your files (ROM + GApps and root implementation of preference).

Followed above procedure and now everything is working fine - many thanks.

Quick update from my last post about battery not charging properly.

I've done a few full 100% to 15% cycles and uninstalled adblock which was hogging my battery for about 15% during one of the cycles.

And what do you know battery is charging just fine.

Though now I'm stuck with chrome with no adblock as warp browser seems broken. Anyone can recommend browser with an adblock?

Cheers.

Good morning, I installed the 7.1.2 Grouper OTA-Package (Build 20170505), without problems and it works fine, then the Gapps for 7.1.x (I used Mini_Dynamic_GApps-7.1.x-20170415.zip) but they made a mistake and at the end Install SuperUser v2.79SR3 without errors but blocked my Nexus 7 32GB
[Nexus 7 Android Development] pehlm:
You mean you get a bootloop after flashing SuperSU? If you flashed SuperSU without installing it systemless you get bootloop, you must before the install of SuperSU open a terminal in TWRP and there run the following line, without quotes: "echo SYSTEMLESS=true >/data/.supersu", it forces systemless install. Then go back and flash SuperSU, the device should then boot. Hopes it helps.
[Nexus 7 Android Development] AndDiSa:
One additional remark: you need to reflash the ota-package, too. Due to non-systemless SuperSU the system partition was modified and due to low space probably not written correctly. So I would start again, e.g.

- flash ota

- flash gapps

- flash SuperSU systemless
[Nexus 7 Android Development] Jascha2016:
Ok, Thanks,

but also installing the Gapps have locked my tablet on the google logo, I'll try and let me know.

Updating :

This is the result of the BeansGapps-Mini-7.1.x-20170415.zip gapps, appear to be incompatible and tablet stuck google logo, now reinstalling the rom
[Nexus 7 Android Development] AndDiSa:
... as I saw on the image you posted you erased system and then tried to install gapps. This will not work, you need to install the ROM and then gapps without cleaning system before.
[Nexus 7 Android Development] Jascha2016:
Thanks endless, problem solved, correctly installed Gapps and Supersu. A question when I want to wipe I select everything except the internal storage is right?
[Nexus 7 Android Development] AndDiSa:
For a full wipe you select everything except internal storage, when you are updating the rom wiping cache and dalvik-cache should be suffient unless you are coming / moving to a different rom.

[Nexus 7 Android Development] AndDiSa:
[MENTION=4051694]masantula[/MENTION] No, neither of these problems I can confirm from my side. Do you have a tilapia or a grouper device?
[Nexus 7 Android Development] masantula:
I have Tilapia. I used the same GAPPS and ROM used in OP post.
[Nexus 7 Android Development] AndDiSa:
[MENTION=4051694]masantula[/MENTION] unfortunately I do have only a Grouper device available ... I am using the device tree from [MENTION=6754437]millosr[/MENTION] for building for the Tilapia device, probably he might have an idea what might cause the issues ...
[Nexus 7 Android Development] aolins:
I have Tilapia and do not have any of these problems. I am using Open Gapps Pico. The only issues I was experiencing are related to performance, though (I have quite many productivity apps installed). I had to change the kernel auditor to on-demand and play with Zram settings to get things smother. And, finally, I flashed the good old Parrotmod, and this also made quite an improvement. Now the tablet is stable and quite smooth.
[Nexus 7 Android Development] masantula:
Much appreciated for sharing this with me, i will look into detail what the cause of the problems i am facing are. Hopefully be able to fix it without a need to reflash the ROM again.

Thanks again :)
