I installed rom ([ROM] 6.0 Android MarshMallow Pure AOSP for Google Nexus 7 2012 WIFI by vocoderism) on nexus 7 grouper along with gapps, supersu. It works ok and BT is working which i could connect my BT keyboard to it. However, after I install parrotmod (ParrotMod_Grouper_Universal_2016-10-14_19.33.56.zip). The BT stop working and pop up "Unfortunately, Bluetooth Share had stopped".

May I know where I can go from here to fix the BT so that it can be use?

Thanks in advance.
[Nexus 7 Android Development] AndDiSa:
Reflash the ROM to remove parrotmod. Parrotmod is exchanging some libraries and settings which might be incompatible with the ROM.

open failed: EACCESS (Permission denied)

Dear experts,

I am using a Nexus 7 2012 Tiapila and got an exception when reading files from my SD-RAM.

I've installed AOSP 6 on it using the TWRP method after a factory reset (format).

I've also installed:

* open_gapps-arm-6.0-pico-20160312 and

* BETA-SuperSU-v2.52

Setup works fine. The problem is access files using fore example "Mobi OfficeSuite". I get an Error "open failed: EACCESS (Permission denied))."

Example:

* I download one file using my owncloud Client.

* I try to open this file using "OfficeSuite" --> I gen an error and can't acces the file.

Additional Infos:

* If I use ES-Explorer to see user/access rightes for this file I see that the file sould be accessable (read:yes/write:yes/hidden:no).

* After reboot I OfficeSuite can access the file.

I am happy about any idears

thanx

[Nexus 7 Android Development] vfilipch:
Thank you!

It works better than any other ROM (for me)!
[Nexus 7 Android Development] AimiFox:
I know this is an older post, but I suspect others are going to encounter this problem.

Android 6 introduced a different permissions system, some older apps do not "know how" to request SD or other permissions defined as "dangerous".

It is meant to be backwards compatible but that does not always work. You can check permissions in app ops and perhaps grant it there, this may or may not work.

More information here.

Hi guys

I've discovered this nice rom that works fine (with parrotmod installed) on my old and slow Nexus 7 tilapia....the only problem is that audio randomly stops working (audio out but audio in too, microphone is not able to intercept any sound).

It seems that audio fault occur after a shutdown/reboot; If I shut down tablet with audio working, when rebooting audio is not working.......but If I reboot again nothing changes. I noticed that sometimes audio return to work after waking from standby....however is a weird behaviour.

Anyone knows if is there a solution to this issue?

N7 is Flying

installed the ROM following these steps:

wipe all

update recovery to twrp 2.8.7.0

in mount if you have a flag on system remove it

then install rom,gapps and supersu

and after first boot

tried fix for Auto Rotate.

Just click on auto rotate from notification toggle, it will show portrait or landscape depending on which mode you are stuck.

After that reboot the tablet.

after this last reboot Sound and everything working Fine & Dandy.......:laugh:
[Nexus 7 Android Development] ZeRo2o9:
followed this and my nexus 7 is running and restoring my apps, thanks :good:
[Nexus 7 Android Development] ho0o0o11111:
I also have sound problem. No sound after reboot.

The following steps are how I fix it.

1. plug in headphone

2. open apps for sound (I use clock)

3. play some sound. The sound don't come out from headphone, but speaker (weird)

4. unplug the earphone

Then the speaker works fine until next reboot.

Other than this issue everything is fine for me. I don't have auto-rotate issue etc.

Very smooth and stable.

Thanks for bringing Marshmallow to our Nexus 7. :)
[Nexus 7 Android Development] skooter32:
Hi so a done another clean install and sound is still broke root app deleter don't work kernal tweaker don't work and Google play services crashes any ideas?
[Nexus 7 Android Development] yogesh1998:
For auto rotate, i posted that fix, but it dosnt work.

Even a normal reboot does the job, but again auto rotate stops afer a certain point of time.
[Nexus 7 Android Development] cgm8:
If the auto rotate fixed, it will be a perfect ROM. Dam fast and stable compared to any lolipop and KitKat ROMs
[Nexus 7 Android Development] steviemch:
Downloaded and flashed a few hours ago, using the op gapps, and after a few hiccups with the initial flash (which also happened on mako) this rom is flying. The difference compared with lollipop is unbelievable. Sound and auto-rotate work with no problems (unless an app like adfree opens in default landscape mode) and I've also got now on tap working after converting the Google app to a system app. Cast screen also works from the quick tiles even though a toast notification states "this device isn't optimised for cast screen".

I just hope the speed and smoothness doesn't degrade over time as it did in lollipop.

Many thanks for porting this to our old grouper :thumbup:

Edit - Sound completely disappeared after a reboot, but returned after using, then removing headphones. I'll reproduce when I have time and get some logs.

Edit - [MENTION=4831205]vocoderism[/MENTION] I've reproduced the sound issue and temporary fix (reboot - no sound - plug in headphones - open google music - sound returns through headphones - remove headphones - sound returns through speakers). Link to log included. Let me know if you need anything else.

Awesome ROM. N7 flies just as others have reported.

To deal with the autorotation bug, I use Netflix to force landscape and Instagram to force portrait. Hope this helps others until we get a permanent fix.
[Nexus 7 Android Development] gedster314:
Autorotation issue here too. Battery life seems a little short too. I have not been using my N7 for over a year and when I charged it, it was completely dead for 30 min before I got a charge icon. It very well could be my battery is bad. I'll order a new battery one of these days. I missed the LP roms but this one does seem to be really nice. Its like a new tablet again.

Thisbis completely normal for me. When I don't charge my N7 for 2 days, it does the same thing. It did this even, when it was new.

If you want to test your battery, you can use "Battery Monitor Widget". It measures the capacity of your battery during charging.

i also have the sound bug BUT when i toggle the screen rotation and let it rotate 1 time the sound comes back again.

Flashing now. I cleared caches and system (dirty flash). Flashed Rom, Banks Gapps, su 2.52. Booted fine, took about 4 minutes. One thing I would suggest is changing boot animation to default mm one, much more interesting. I change it after but be nice in the rom.

Edit: looks like Banks did not install play services.

---------- Post added at 10:42 PM ---------- Previous post was at 10:28 PM ----------

What do you mean with

Execute full twrp backup first on recovery?
[Nexus 7 Android Development] FirePsych:
When you go back into TWRP, choose Backup and back up your ROM. In your case, there might not be anything to back up.

I you're restoring your last working 5.1.1 ROM in order to download the latest 6.0, the you probably don't have to back it up again if you haven't made any changes.

Once you've downloaded the new ROM and GAPPs, boot back into Recover /TWRP, do a full wipe including System, flash the ROM, wipe dalvik and cache but NOT system, flash GAPPs, wipe dalvik and cache again and reboot.

Personally, when flashing a new ROM, I flash the ROM, wipe dalvik/cache, reboot. Make sure the ROM works okay, the boot back into recovery and flash GAPPS.
[Nexus 7 Android Development] r-l:
I normally do that, but as you can read above i lost twrp after flashing the rom (updated link) also i can't flash the gapps from the op. It gives an error
[Nexus 7 Android Development] FirePsych:
You lost TWRP? That's a picture of TWRP in you post.

#Vocoderism was uploading a new update. That might be why you had difficulty downloading the ROM.

As for GAPPS, not sure. Check the different threads to see what Packages people have found that work.
[Nexus 7 Android Development] adeelraj:
If system is mounted then unmount if unmount then mount in twrp

[Nexus 7 Android Development] dookie23:
So performance-wise, MarshMallow is just as bad as Lollipop? I was hoping M would be better or at least close to KK. :(
[Nexus 7 Android Development] r-l:
Has to do with the cheap hardware asus used in the n7. The Nand chip is terrible. F2FS fixes it a little for me on LP but it still lags and freezes a lot. That's why i think the n7 is a piece of crap and a waste of my money.

Cause my data and cache partitions are formatted to f2fs

And if i convert f2fs to ext4 my internal storage will be wiped which has important files
[Nexus 7 Android Development] dookie23:
Are you using a lot of different apps on the N7? I am just trying to see if I should stick with KK for now or jump to M.
[Nexus 7 Android Development] steviemch:
76 apps, which were barely usable on KK (for me) are now speedy with no lag. Backup KK and flash the rom and give it a try.

:good: 6.0_Grouper-MM working fine, version Oct 19, 2015 , with Gapps-mm-fix.zip I'd suggest the option: start as a new device, because anyway after entering your gmail account, it will restore. Choosing another option, like restoring to an anterior day doesn't work. I did a factory reset and a full wipe, ( i guess that a full wipe would of been enough, but i didn't knew what he meant by "unmount system" so I've decided to wipe it all. ) Then I've installed the 2 zip files with twrp and a OTG flash drive. So far so good, I'll report if I see any bugs. At first glance , it look fine... Thanks a lot. Good job !

I can say that the first version gave me a lot of sweating , trying to flash it, nothing was working right ! But I've learned a lot of new things.

[Nexus 7 Android Development] adstraylight:
[MENTION=4831205]vocoderism[/MENTION]

The screen looses autorotate after a long period of deep sleep, I've just had catlog running while trying to make it rotate and nothing appears in the log. It's like the sensor simply isn't there. It's the same when toggling the quick settings switch, no response in the log. The only way to reset it is to reboot.

When the rotation is working, you get messages like this :

10-20 04:03:45.443 I/InputReader(520): Device reconfigured: id=2, name='elan-touchscreen', size 800x1280, orientation 0, mode 1, display id 0

when it is stuck there is nothing like that at all, no related errors either.

I don't think it is linked to the sound thing, as they appear to happen independently.
