Are custom boot animations some how disabled on this rom?
[Nexus 7 Android Development] AndDiSa:
It's almost plain AOSP, no additional features beside f2fs support and some performance tweaks.
[Nexus 7 Android Development] Dodgexander:
I know it was asked earlier but I'd like to ask again, could you include this patch so open gapps can be installed without start up errors? It would be nice to fill up the system partition a bit more to save space on data.

Also perhaps to help others when disabling journalling on ext4 partitions, the manual steps included within the link from the OP are outdated and do not work any more. I followed the steps from this post earlier in the thread. Credit [MENTION=4908427]UCHIHA[/MENTION]
[Nexus 7 Android Development] AndDiSa:
[MENTION=5199968]Dodgexander[/MENTION] the patch was already included (some time ago. Disabling / enabling journalling on ext4 is still working as described in the link, but you need to take care that you do it in recovery and that you have unmounted the ext4 partitions before entering the command. Nevertheless, you can use the scripts from [MENTION=4908427]UCHIHA[/MENTION], probably I'll also modify the update zips that you are able to remove journalling on updating the ROM.
[Nexus 7 Android Development] guidocioni:
Is anybody having problems with WiFi? When the device goes to sleep wifi is turned off for me... Unlocking the device cause a new connection (surprisingly enough fast) to the WiFi which is again lost when the screen is turned off. I know that this is a well known bug but I basically tried everything (wipe cache, dalvik, change wifi sleep policy...). I was wondering that maybe someone with the same ROM had problems..
[Nexus 7 Android Development] AndDiSa:
It's not a bug, it's a feature ... ;)

To be serious, you can disable that in WiFi-settings -> enhanced -> WiFi enabled when idle (only when connected / always / never)
[Nexus 7 Android Development] guidocioni:
Already did that :crying:
[Nexus 7 Android Development] Dodgexander:
[ROM][6.0.1_r10][MMB29T][F2FS/EXT4]Android 6 AOSP on Grouper

I followed the manual instructions in the link outside of recovery so perhaps there was where I went wrong. A mistake on my part but I didn't see instructions to use steps in recovery on the link. I kept getting an error about PIE instructions only supported.

I don't know what the problem is with open gapps then if the patch is already included (thanks). I get force closes of setup wizard and play services. It's not permission related either since I deleted setup wizard apk and tested enabling all permissions for play services and the fc still happened.

It's strange, Pico gapps worked okay for me in a previous build, more recently I tried the aroma gapps installer and the micro package and both didn't work. I tried benzo gapps even in your op and they caused force closes! In the end the only to work was banks gapps.

Perhaps an idea for this rom would be allowing f2fs all. Having f2fs on system has no gains, but it would avoid messing about with disabling journalling.

The other suggestion I would make is adding faster charging support to the kernel. Currently charging is very slow.

Edit# I also have the Wi-Fi turning off with screen off as described above. In settings I have Wi-Fi enabled when connected.
[Nexus 7 Android Development] tedkunich:
If your tablet is slow to charge, replace your USB cable and or your USB port on the tab - they do wear out over time. I replaced my port last week (USB otg stopped working) and I charge in less than 4 hours from nearly dead.

T
[Nexus 7 Android Development] AndDiSa:
[MENTION=5199968]Dodgexander[/MENTION] 'only when connected' means connected to a power supply ...

F2fs for system does not make sense and you don't need to disable journaling on /system

For the force closes: did you wipe dalvik after flashing the new gapps?
[Nexus 7 Android Development] Dodgexander:
Actually it's funny you mention that because I just replaced the USB port/audio jack and the device still has problems charging. I have a nexus 5 myself and when I use it's own charger which works fine on the nexus 5, my sister's nexus 7 charges slow. Even with my fast 1.8amp charger I use for my nexus 5 often it charges slow.

When I check charge rate using ampere on the market the nexus 5 pulls over 1.6 amp sometimes. On the nexus 7 the same charger pulls next to nothing. I've read about common charging problems with the nexus 7 but I can't make sense of this.

Thanks. So disabling journalling is only a performance increase for writes? For the force closes I get them even after wiping everything. Are you supposed to wipe cache and dalvik afterwards too?
[Nexus 7 Android Development] AndDiSa:
Updated to 6.0.1_r13 (MMB29U) with the Februar 2016 security fixes, new Link in the OP.
[Nexus 7 Android Development] Codster314:
Bug Fixed?

Thanks for the update. Love the ROM. Very speedy.

I was wondering if you fixed this bug? I noticed some other ROMs have found a fix for it, namely the OmniRom, in his Jan 21st Update.

http://xdaforums.com/nexus-7/development/rom-omnirom-6-0-1-homemake-t3282311

I don't have a link to the specific patch he did to fix it, but he does have his source on Git. Not too sure if that's helpful to ya, but just letting you know there is a fix out there floating around.

Thanks again for the ROM, I use this since I find it the most responsive out of the bunch.
[Nexus 7 Android Development] AndDiSa:
[MENTION=7056085]Codster314[/MENTION] thanks for the info, I didn't know that yet.I'll try to include the fix, too.
[Nexus 7 Android Development] x3dnd3x:
Can I just check is the latest 0203 build comes supported with F2FS? :confused:
[Nexus 7 Android Development] AndDiSa:
It's supported since the mid January ...
[Nexus 7 Android Development] MicheleFrost:
Thank you so much for the ROM, really brought my n7 back to life.

I noticed that it's even more snappy with a few kernel adjusts (governor etc) as the ones you can simply set with root apps like Root Booster.

Just one thing not working properly to me: updates. Every time I have flashed the ota file so far, I had FCs on many apps and processes, the configuration wizard bug etc. Everything fine instead when I installed with a previous wipe. Any hints o on this?

Thanks
[Nexus 7 Android Development] AndDiSa:
How do you update? Did you wipe dalvik-cache? Did you re-flash the gapps?
[Nexus 7 Android Development] N7Tester:
I asked a different ROM developer the same question and I hope you don't mind me asking you here but is it possible to implement HEVC support in the next build? It is clear to me that Grouper doesn't have on-chip hardware decoding for x265 but I tried a Lollipop-based ROM (XenonHD) and it seems they managed to implement it in their build. Without any custom codecs MXPlayer runs x265 8bit 720p flawlessly in HW mode and the device doesn't get hot, longer battery life in terms of movie play time and no frame skipping - an improvement over the SW mode. With custom codecs it's even better.
[Nexus 7 Android Development] MicheleFrost:
Sure, I wiped dalvik. I tried either reflashing gapps and not.
[Nexus 7 Android Development] AndDiSa:
Normally booting to recovery, flashing the OTA, re-flashing the gapps, wiping dalvik and finally rebooting should be fine and should not lead to force closes.
[Nexus 7 Android Development] x3dnd3x:
How about the latest recovery? Is it F2FS enabled as well? :confused:
[Nexus 7 Android Development] AndDiSa:
There's no recovery included within the ROM images, but TWRP 3.0 should support F2FS.
[Nexus 7 Android Development] imitev:
Is there a possibility to flash the latest version over the 20151209 without wiping the user data?
[Nexus 7 Android Development] AndDiSa:
If you are already on an older version of thus ROM, there is no need to wipe. You only have to wipe coming from a different / non AOSP ROM.
[Nexus 7 Android Development] 1T TAB:
Threads like these make me happy that the community of our nexus 7 is still so active and there are a lot of people like me who still use a nexus 7 even in 2016.
[Nexus 7 Android Development] fat-lobyte:
Hi, I am currently trying to pick out a ROM for my device. What's the advantage of this rom comparet to like... this: http://xdaforums.com/nexus-7/development/rom-6-0-android-marshmallow-pure-aosp-t3226012

Also, is there a way to turn off zRAM? I've read that it does more harm than good when it comes to lag (not sure though).
[Nexus 7 Android Development] fifthelement:
I'm getting constant Google play services force close after a clean install and flashing Benzo-gapps. I have granted all permissions to Google play services and play store as well. Also cleared cache and Dalvik Cache. any recommendations ?
[Nexus 7 Android Development] AndDiSa:
[MENTION=4879521]fat-lobyte[/MENTION] you can use e.g. Trickster-Mod to disable zram. BTW. I noticed similar behaviours, so most likely I will switch off by default in the next release.
[Nexus 7 Android Development] fifthelement:
For those who get google play services force close issue, use this gapps : https://www.androidfilehost.com/?fid=24052804347833783

It works perfectly. I dont know what is wrong with other gapps like benzo or opengapps. they all force close for me even after providing all required permissions.
[Nexus 7 Android Development] offbeatdave:
This the one I use too as it's the only one that I've had working perfectly! The other often gave issues.
[Nexus 7 Android Development] SilverJS:
Just wanted to say, thank you so much! This is exactly what I was looking for - a ROM that is pretty much as Google would have pushed to us, but with F2FS support. Fantastic.

And, thanks to the above poster about the GApps - those were the first I tried, no issues.

Quick question : I know the info is here and there in threads, but it's a bit all over (and assumes knowledge I don't have) so I'm not 100% about how to disable journaling. I understand I have to flash a script (already have that), and that I have to do it for the system partition (as data and cache are F2FS). I also understand I have to unmount the partition first. My questions are :

1. How do I flash the script to a particular partition in TWRP?

2. How do I unmount the partition?

Thanks!
[Nexus 7 Android Development] AndDiSa:
There is no need to disable journaling on /system because it's read only.
[Nexus 7 Android Development] Teiby:
And when do I install the ROM? After downloading the OTA-Package?
[Nexus 7 Android Development] offbeatdave:
The ROM is the OTA package, so install it at that stage.
[Nexus 7 Android Development] Teiby:
Okay so step 4 should be before step 2? Download and copy to internal storage and install in step 4 (download while in recovery isn't possible)
[Nexus 7 Android Development] offbeatdave:
Yeah, get it downloaded first!
[Nexus 7 Android Development] AndDiSa:
[MENTION=6019900]Teiby[/MENTION] sorry for the misleading description in the OP, I've corrected it now..
[Nexus 7 Android Development] Teiby:
Thanks. Works perfectly. Also solved a 100% disc load bug that made the tablet sometimes unusable (on Android 5.1)
[Nexus 7 Android Development] tom_taylor:
All working great for me - wiped clean and flashed from scratch, setup and startup wizard loaded ok and restored apps too from previous backup - may take a while on initial startup - be patient ;)
[Nexus 7 Android Development] ZehelSitchel:
Just wanted to point out that the dates on the most recent versions are listed as 2015. Thankfully the package also has the date and it's correct so it's not that big of a deal. But I just wanted to point that out as I am about to try out this ROM!
[Nexus 7 Android Development] AndDiSa:
Thanks for the hint, I've corrected it now. :)
[Nexus 7 Android Development] AndDiSa:
[MENTION=7218543]N7Tester[/MENTION] this ROM is (almost) fully AOSP and I would like to keep it in this way. If there is a minor modification to be done e.g. in the kernel / device configuration and someone will give me a link to the modifications to be done I probably will have a look at it but without guaranteeing anyhing.
[Nexus 7 Android Development] N7Tester:
Thank you for your answer! I hope someone will post something because I'm no tech-savvy and unfortunately I don't know what is to be modified for HEVC to work.
[Nexus 7 Android Development] djkinetic:

[Nexus 7 Android Development] sco0ter:
Have flashed this ROM and must say that it is excellent. I primarily use my nexus as a navigation device in my car but the lollipop update made it almost unusable. Now this works flawless and no more slow charging either. Excellent work thanks.
[Nexus 7 Android Development] frickingphil:
Holy hell this ROM is clean and quick! Thanks for the great work!

I'm having this issue with writing to /sdcard/ though, sometimes apps can't write to anything in /sdcard/. Anyone else having this issue, or got any ideas on what I could do to fix? Thanks!
[Nexus 7 Android Development] AndDiSa:
[MENTION=2403799]frickingphil[/MENTION] did you enable write access for those apps in ther permission settings?
[Nexus 7 Android Development] marcw4:
Camera

Does the camera work? I get device not found error when trying to access the camera. Last night I wipe all data and cache and still no camera.
[Nexus 7 Android Development] AndDiSa:
Yes, why not? What camera app do you use? Did you grant permissions?
[Nexus 7 Android Development] marcw4:
when ask,I granted all yes. There is no camera app to open, so I was using hangouts to open the camera. I cleared the permissions a few times and still no success.

I also installed famera fv5 and a few others, all state no camera installed.
[Nexus 7 Android Development] AndDiSa:
I do neither have problems to do video calls with Hangouts nor to use a camera app. It must be something different, not related to the ROM.
[Nexus 7 Android Development] droidmarc:
I only have a very basic setup for this tablet. only google apps and doggcatcher. The camera was not working after i installed the rom and only hangouts.

There is no camera app in the app draw.
[Nexus 7 Android Development] frickingphil:
I did, but it was still erroring. For reference, this is what fixed it for me:

[Nexus 7 Android Development] AndDiSa:
That's exactly what I meant, you don't need a script you can also do it manually ?
[Nexus 7 Android Development] frickingphil:
Well, the weird thing was that here's the important part from the post I linked:

My app permissions were set correctly but somewhere along the line of me flashing like 3 different ROMs in 3 days, the permissions of /sdcard/ got messed up. Like, the actual filesystem permissions. I started noticing something was amiss because even when running ES File Manager as root, I still was denied access to move a file into a folder.
[Nexus 7 Android Development] AndDiSa:
Blocking access to (external) resurces is the key feature of SELinux (the basis of Android 5.1+). You explicitly need to grant permissions in the app settings otherwise access will be blocked.
[Nexus 7 Android Development] akoppes:
The old build-in camera app doesn't work, regardless of permissions.

Install the Google camera v2.5, which does work.

Google for the apk.
[Nexus 7 Android Development] williamlaw:
Great after installed for several days !!

But it then got lag / freeze / reboot ......

What's should be the problem ?

Thanks
[Nexus 7 Android Development] AndDiSa:
Most likely the zram got messed up due to many different applications running /kept in memory. I noticed such a behaviour, too, and I am investigating. Unfortunately I didn't find a solution yet ... beside re-booting :(

Updating to last OTA

Can`t update to last (r13) OTA

Hi, AndDisA! I`m using your great ROM for a several months. And I haven`t any problems with it. But now i can`t update my r10 ROM to r13 - i have the "error 7" while i trying to update it via TWRP 3.0.0.0. I don`t make any changes in system partition and don`t install any patches before. Can you help me with it? I`ll be very pleased. Thx for your work.
[Nexus 7 Android Development] AndDiSa:
I cannot yell you what might be wrong, because I am normally updating directly using the system.img and boot.img and fastboot. Did you check whether the md5 sum of the download is correct?

Another option would be: erase boot and system partition and try to flash the OTA package on a clean base.
[Nexus 7 Android Development] BleedingSun:
Thx for your reply! I'll try to flash boot and system images via NRT. Then i need to flash gapps as usual? There is nothing different between OTA update?
[Nexus 7 Android Development] AndDiSa:
No, there is no difference and yes, you have to re-flash gapps as usual. The only problem you might discover: I did not provide the images for all versions. The next release I'll provide both versions again.

Question: any way to enable / add ADB over Wi-Fi to this ROM? I can't seem to find it in settings...

Also, would anyone have a kernel recommendation if I want to overclock but also keep ZRAM enabled?
[Nexus 7 Android Development] AndDiSa:
[MENTION=2403799]frickingphil[/MENTION] As this ROM is (almost) AOSP, there are no additional settings, but you can use TricksterMod to enable ADB over Wi-Fi.

As for as I know [MENTION=4948627]daniel_hk[/MENTION] has kernel which supports overclocking and which is running with this rom, too, but I am not sure whether he has ZRAM enabled.
[Nexus 7 Android Development] frickingphil:
Thanks for the quick reply!

Unfortunately, I was already running his kernel before and it doesn’t have zram enabled.

Any chance you can kick out an overclocking-ready kernel version from the one you’re running in this rom? Or is that asking too much, and I should get started looking up how to roll my own kernel :P

Not really issues, but I didn't get it to install systemless. Probably I need to try a forced systemless installation. With v2.62 systemless is working out of the box ?

If you were flashing the right zip file, you might want to check with the ParrotMod developer on the bootloop issue.

I've just flashed your rom and it runs fast (with the help of the f2fs). It failed with the pico opengapps (i got an error related the startup of the play services), but with the benzo packages everything goes right, no issue with supersu 2.68.

I found a critical bug: when i try to disconnect (umounting or pulling away) a usb key via OTG the tablet freezes and reboots. Same happens with stickmount.

There isn't a service (calendarsync) in the benzo app to sync the MM calendar with my account, i don't want to install the google calendar. Solution???

Thanks for your efforts:victory:
[Nexus 7 Android Development] Codster314:
I've also noticed that OpenGAPPS Nano (which is roughly equivalent size-wise to the Benzo ones), also do not install right, and won't launch the SetUp Wizard during the first boot. However, the Benzo ones work fine.

It would be nice to get the OpenGAPPS working right, since the Benzo ones are over 5 months old, and you have to install the Apps, and then manually update the apps (like Store: which is a pain) again after just flashing them. Whereas the OpenGAPPS are all up-to-date after the flash.

I'd definitely prefer using the OpenGAPPs if I had a choice. I notice most of the other ROM's here support/prefer that distribution of Gapps.
