Couple of questions about update installation (I have version from June 2018 on Grouper):

- Is Install pico Gapps for 7.1.x mandatory step since I have it installed?

- Do I need erase the system partition completely before applying the OTA package? Will my settings and data be left intact?

Thanks
[Nexus 7 Android Development] Aker666:
You have the instructions and the answers to your questions on the main post..........

- Update Installation

1. Boot into Recovery

2.1 Install 7.1.2 Grouper OTA-Package (Build 20181016) (md5: 1a9d0071f4de1e2eb6342de027868e98)

or

2.2 Install 7.1.2 Tilapia OTA-Package (Build 20181016) (md5: 3bf28b53637f444f9684a0853942011c)

3. Reboot into recovery

4. Install pico Gapps for 7.1.x

5. Wipe cache/dalvik-cache (optional, but suggested) <---You only wype the cache so you won't lose anything.

By the way, is there any problem with the servers? I can't download the "grouper" file to update my device.

Regards!

Is there a chance that the tilapia zip is corrupted? I am fairly capable with such things and to me it looks corrupt but I see there have been a number of downloads already.
[Nexus 7 Android Development] AndDiSa:
AFH looks a bit slow to me at the moment ...

Edit: ... and the file is corrupt when having it downlaoded. I'll re-upload the file ...

Edit2: tilapia file is newly uploaded and the links are updated
[Nexus 7 Android Development] Sam Nakamura:
Needed 3 attempts to get it for my grouper but it eventually worked... It's something on their end, yes!
[Nexus 7 Android Development] Swanee123:
The re-upload of Tilapia installed perfectly. Thank you!
[Nexus 7 Android Development] 1990clb:
Just took me about an hour and a half to download the 20181016 grouper file so if anyone needs it here is a link to my Google Drive:

Thank you!
[Nexus 7 Android Development] phil0sophic:
BIG, BIG thanks for this!

My son gave me a Grouper that he said was only good for a coaster, as using it would drive him to drink.

I rooted and installed this ROM and now he wants it back, no way Jose! This works purrfectly, ain't no 8 Gig octacore but the price sure was right. No issues whatsoever installing or usage hope the purrformance holds up over time.

Thanks big-time. :good:

Memory leak when watching YouTube (Bug ?)

This ROM is work great on my Tilapia, but I have some problem, When I watching YouTube (only 1 hour) my device slow down and got stuck, I tried to clear recent task and watch RAM Free it's only 82MB left, reboot is solve this problem but it's still persist when I watching YouTube again, I use another streaming app eg. newpipe but no luck, got same problem

PS. I use this rom over 4 month, everything smooth, I found only this problem
[Nexus 7 Android Development] schmatzler:
I got my Grouper for 30 bucks. It's almost never been used, battery life is still great and the previous owner thought it was junk because of the laggy stock ROM.

Now I use it to play games on it. Galaxy on Fire 2 is so much fun on this thing! :D

I have a grouper and this problem doesn't happen for me there.

But I also use microG instead of the regular GAPPS.

The device is used 8 hours a day to play YouTube music at work for me and my colleagues. I wouldn't rule out a Tilapia specific problem, though. Maybe someone else can test this.
[Nexus 7 Android Development] jackjsa:
I using microG and installed little apps(that hibernate with greenify), but I format data and cache partition to F2FS.
[Nexus 7 Android Development] mikefive:
first i had to commit: what a great rom! :D

..with microG installed, it's fast and totally useable for all my daily tasks. I also get my device for a low price (about 30 bucks -as mentioned before-) and i must say: i'm very impressed with the result :)

-no bugs as far as i can see- the only thing worth to mention is, that it slows a _little_ bit down, if i activate greyscale modus via developer settings (i use it for night mode, as it evectivly filters out blue light and still looks good ;))

i just want to say "big thanks!" for still supporting such an "old" device and for all the work you spend to get this working (especially andDiSa -but also all other contributors)

keep up the good work! :good::good::good:
[Nexus 7 Android Development] puffel86:
Since last update Spotify is permanent closing after some seconds. Cleaning cache and data from spotify doesn't help. Any suggestions?
[Nexus 7 Android Development] OlliWi:
Please provide a logcat logfile to help investgating this issue.
[Nexus 7 Android Development] jackjsa:
Here's my device meminfo after got memory leak, I don't know what cause this problem, after reboot I have RAM free 540-480MB but mem leaking grow every time when I watching YT

Update: I clean flash rom, but can't solve this problem
[Nexus 7 Android Development] Alex_Lyt:
I have the same trouble on grouper with microg. Have to reboot every 2-3 hours of video playback via mx player
[Nexus 7 Android Development] Sam Nakamura:
I use my Grouper almost every evening to watch YouTube (the vanced version from Magisk Repo) for an hour or two and have open GApps pico installed - never had an issue like this at all...

May it be that it's actually a MicroG specific thing?
[Nexus 7 Android Development] Aker666:
I use Youtube Vanced (rooted version) and I don't have this problem.
[Nexus 7 Android Development] Alex_Lyt:
No, it is not. I had the same trouble with opengapps installed. Actually that was a reason for me to try microg. I thought that gapps are causing that memory leak, but it must be rom itself (
[Nexus 7 Android Development] Sam Nakamura:
If you have a chance to backup and clean flash this would probably be a appropriate situation to try it, again I use my Grouper with the mentioned setup very regularly and haven't seen this once, it's stable & "fluid" for me!

Also installing each app one by one, without restoring via titanium backup could lead you to a possible solution, not sure what else to suggest...
[Nexus 7 Android Development] Alex_Lyt:
I always use clean flash on a tablet. There's nothing to backup there. I'm using it only to watch videos...

---------- Post added at 09:48 PM ---------- Previous post was at 09:41 PM ----------

Some groupers were bricked on official update to android 5, but most of them not. So it is not a surprise for me, that unofficial rom works well on your grouper and freezes on mine :D
[Nexus 7 Android Development] Sam Nakamura:
lol mine was among them and I later replaced the motherboard to get it back to life! The classic emmc brick bug due to cheap Kingston crap, this however upgraded me from 16 to 32GB for only 20 bugs, the operation itself is simple as it can be and this also got me a quality memory chip by HYNIX...

However I honesty have not a single clue what else to suggest you! :)
[Nexus 7 Android Development] jackjsa:
Same here, I clean flash and use microg instead of gapps, but mem leak problem isn't gone, I agree with you! that problem may be cause by rom itself :rolleyes:

PS. I try many way but can't solve this problem.
[Nexus 7 Android Development] AndDiSa:
[MENTION=5304398]jackjsa[/MENTION] [MENTION=7844548]Alex_Lyt[/MENTION] would be great to have some more information about this issue, i.e. which ROM do you currently have installed? Other tools / settings (like kerneladiutor, parrot_mod, ...) which are influencing memory management? ... and a logcat containing the issues would be best.
[Nexus 7 Android Development] wutzin:
Hey Andi, thanks so much for keeping our Nexus 7 devices running much better than the original Google ROM ever could...

Much appreciated!
[Nexus 7 Android Development] puffel86:
Today i updated the Spotify app and since that the app closing problem is gone. ?
[Nexus 7 Android Development] jackjsa:
Thanks for your reply!

I have installed latest build of your rom (but format /data and /cache partition to F2FS) I don't install any kernel & ram management, use only greenify for hibernate some apps, I will provide logcat here https://drive.google.com/file/d/1L6G3mb1-G3mwonevtbcVqWeegcdx4Tnp/view
[Nexus 7 Android Development] :
That is now my preferred upgrade process (dirty flash a thing of the past) I used to use Titanium too to restore apps but not now. It became too uncertain and could lead to random and niggling problems. Wipe and clean install for me every time now.

Sure, it takes longer (particularly with a slow internet connection!) and some apps (Sygic!) have to have data reloaded too, but I find it the only certain way to ensure a trouble free upgrade.
[Nexus 7 Android Development] AndDiSa:
[MENTION=5304398]jackjsa[/MENTION] I can see in the logs that you are running Xposed and Greenify ... sorry, but in thoses cases I cannot help you out as those processes might have a big influence on the overal behaviour of the ROM.
[Nexus 7 Android Development] Alex_Lyt:
I use your last 1016 build and latest microg. Have no any apps, that can influence on the ROM. Will provide a logcat soon.
[Nexus 7 Android Development] jackjsa:
OK, but I have this problem before install xposed and greenify

BTW I will uninstall both of them and provide logcat again, sorry about that.
[Nexus 7 Android Development] Don_Syleri:
Please can you explain how to bypass the setup wizard?
[Nexus 7 Android Development] luismg:
The tutorial worked for me, thank you very much
[Nexus 7 Android Development] jackjsa:
Now I uninstall Xposed and Greenify that can big influence on the ROM, and clear cache/dalvik cache

here my logcat https://drive.google.com/file/d/1dYfDexylF1ctlLU5OiZ5S1Ygt2fiskSb/view
[Nexus 7 Android Development] AndDiSa:
I had a brief look at the log and really speaking, I don't know what's going on there. I can see, that you switched resolution of the video several times and then after a certain time the InputMethodManagerService is crashing and it is restarted every second.

As I cannot I dentify a concrete issue, I would suggest to do a clean setup without restoring apps using e.g. Titanium and to check whether the issue is still there.
[Nexus 7 Android Development] tombunyon:
I've had the problem of the System RAM usage constantly growing on my Grouper device as well, and I've realized that disabling Ambient display and Tap to wake (or just one of them, I didn't get to experiment much yet) has fixed this problem. Not sure if it'll work for y'all.
[Nexus 7 Android Development] jackjsa:
Sorry to hear that, I clean installed this ROM recently and not restore by Titanium, BTW I do a clean flash again when the latest build of this ROM (for this month) release, if this problem still there, I will report back ASAP.
[Nexus 7 Android Development] Ahkah:
So far I have not experienced any severe problems with the latest version.

However, for whatever reason the Google search bar at the launcher screen looks ancient, with the old Google logo, and it's misplaced, but as far as I understood this is part of the OpenGapps and not part of the basic OS.
[Nexus 7 Android Development] schmatzler:
That's because the dev has used the old Gingerbread launcher from the Android 2.x era.

I welcome this, because it doesn't draw a lot of resources. But it also hasn't been optimized for tablets. Android 3 was the first version build for tablets.

If you don't like that launcher, I'd recommend Nova Launcher. It lets you customize all aspects, including the search bar.
[Nexus 7 Android Development] mkoyskip:
As I haven't been able to peruse for a super long time just some thoughts while I try to catch up from late July--> and today.

- installed Tilapia (20181016)

- of course forgot to root so had to manually boot recovery [TWRP] vol+/etc

- Also now install magisk + pico gapps

My original issue was that my Nexus 3G (tilapia) had random reboots. Haven't yet time to read through the many unread posts yet.. Today left it on all day while driving all day, no reboots? Only issue is hotspot WiFi?

Again, only posting info as I haven't had time yet to read much. Thanks for what you do! Also I'll get off my arse and do some reading on my own. Later.

Also WiFi hotspot not working at all gs9+ ? I'll look into the later.
[Nexus 7 Android Development] jackjsa:
Hi [MENTION=2188693]AndDiSa[/MENTION], Today I have free time, I do a clean flash this ROM (not restore apps by Titanium), but can't solve memory leak problem, it's still there, don't know why,

I watching YouTube 2-3 hours and found this problem, my device slow down and got stuck,

PS. I test again by using mx player for watch online movies but same as YouTube
[Nexus 7 Android Development] Alex_Lyt:
Dev can not help us without logcat. I'm trying to record it, but freezes on my tablet are very sudden. Please try to make it.
[Nexus 7 Android Development] jackjsa:
try this command in terminal

su
logcat -d> /sdcard/logcat.txt

This command dump the log to the screen and exits, if you don't type -d , system will collect logcat every second and can't stop it, that may cause your device freeze

PS. I provide logcat to Dev at post #3187 but he can't identify this problem
[Nexus 7 Android Development] AsrielDash:
Stucked at boot animation

I wiped everything and reinstalled it,but still stucked
[Nexus 7 Android Development] jackjsa:
First boot may take long time about 5-15 minute, Please wait for ART optimization, if you wait it so long time over 30 minute, You're probably try to wipe all partition (included internal storage) and flash it again.
[Nexus 7 Android Development] tombunyon:
While this is true, it takes the Google logo from the Google app, so if you installed the Google app, you would get the new logo.
[Nexus 7 Android Development] Ahkah:
For me it took some days for the device to become that slow that it finally got stuck with BSOD, i.e. it did not wake up any more. So I had to reboot it. Maybe it's a good idea to shut it down over night.
[Nexus 7 Android Development] Nexus7_tilapia:
Hi, The ROM works like a charm since the earliest update but ...

It does only need to reboot the device once a day to release the RAM manually; And those sudden reboots occur while the RAM gets filled completely.

Regards
[Nexus 7 Android Development] Alex_Lyt:
Your logcat was with greenify if i'm not mistaken. Could you please make a new one without any greenify- like apps installed? I don't have my nexus for now.

battery consumption by "cellular network" in airplane mode

[MENTION=2188693]AndDiSa[/MENTION]

Hi.

Thanks for the ROM!

Is it okay that in airplane mode (and without SIM card) "cellular network" still consumes battery? (please see screen-shot)

Device is tilapia.

Hi.

Thanks for the ROM!yeah yeah yeah !! very smooothhhhhh!!

November Security patches are applied

Some guys already noticed that I'had uploaded yesterday the new version with the November 2018 security fixes. The new builds (Grouper and Tilapia) are linked in the OP. Nothing special is in beside the new security fixes.
[Nexus 7 Android Development] aninat:
Hi,

I'm Grouper 20181003 TWRP 3.2.3

When I flashed the latest one, TWRP said success but about phone said I'm 20181003 with Oct security.

Md5 new version is correct.

Is anyone has same problem?
[Nexus 7 Android Development] AndDiSa:
[MENTION=7577834]aninat[/MENTION] Thank you for reporting the bug, unfortunately I forgot to increase the security patch level to 11/05 but be asured that the november security fixes are applied.
[Nexus 7 Android Development] AndDiSa:
[MENTION=9542077]qazerr[/MENTION] the graphic shows only that there was no cellular network signal most of the time, nothing more and nothing less. Nevertheless even when in airplane mode the radio processor will consume some power as it is not switched off completely
[Nexus 7 Android Development] andrei-vn:
hello there guys. is there a similar thread for samsung galaxy note II ( gt n7100) ? I used this thread for my nexus 7 2012 and it is working perfect
[Nexus 7 Android Development] jackjsa:
OK! I will collect logcat again, last night I will collect logcat but my device sudden reboot, I thought because RAM fill up completely cause it reboot,

PS. I uninstalled all apps that similar greenify and clean install this ROM
[Nexus 7 Android Development] shibadoo:
Tried the tilapia build. Dirty flash from your last tilapia build (20161127) and wiped Cache and Dalvik. After booting I get FCs with at least all Google apps (Gmail, Youtube, Play Services, ...). Installing the most recent OpenGapps failed ("failed to map file ...").
[Nexus 7 Android Development] AndDiSa:
[MENTION=980259]shibadoo[/MENTION] you need to flash pico gapps and those gapps need to be flashed after updating the ROM, too. If gapps flashing is failing it's obvious that you are getting errors.
[Nexus 7 Android Development] shibadoo:
Of course I flashed pico gapps and of course I flashed them after flashing the ROM. The FCs I got with the old Gapps which I installed for your previous build.

UPDATE: Managed to install the most recent pico gapps (corrupted download before?). Nevertheless I get FCs at least for all Google apps immediately after booting.
[Nexus 7 Android Development] AndDiSa:
[MENTION=980259]shibadoo[/MENTION] most likely now because the ids of the apps have changed due to the corrupt flash / boot in between.
[Nexus 7 Android Development] akillenb:
Dirty flashed Rom and updated gapps, cleared cache/dalvik, and rebooted.

Later, flashed updated supersu, as rooting was lost.

Playstore seems a bit more sluggish than before.

Music works, but black text on black/greyscale album art is nearly impossible to read when selecting an album. I don't see any settings for the app to change the display.

All in all, very good.
[Nexus 7 Android Development] shibadoo:
Went back to my backup, downloaded ROM and latest pico gapps again and flashed everything again. No FCs anymore, BUT: no radio. When booting it does not ask for the SIM PIN and the SIM is not recognized.
[Nexus 7 Android Development] qitt:
Same for me. It is No Sim Card on Tilapia. On previous build it was OK.
[Nexus 7 Android Development] AndDiSa:
Hmmm. I did not change anything on the device tree, it's from [MENTION=6754437]millosr[/MENTION]. Probably there was a change in the permissions. Without logcat and without device it's s bit difficult to analyze ...
[Nexus 7 Android Development] shibadoo:
Just flashed the tilapia build from [MENTION=4948627]daniel_hk[/MENTION] and there is the radio.... probably it would be worth investigating daniels device tree or even fork it? I would do it if my knowledge of Android would be a little more profound... I could at least provide some log files if you tell me what you need or what I would have to look for.
[Nexus 7 Android Development] AndDiSa:
Probably I'll do so ... regarding the logcat, especially the starting / initialization part is interesting. Probably there is an avc: denial message which prevents access to the radio.
[Nexus 7 Android Development] tpuserhp:
Anyone one dirty flash the latest build and have fstrim installed? Are you able to look at trimmer log entries? I had to do a clean install to get this going on the daniel_hk build. I might need to do the same here on this build.
[Nexus 7 Android Development] shibadoo:
Had to go back to my backup of your last build, daniels build was absolutely unusable for me. Extremely slow, emails didn't open at all, apps did open only after many seconds if they did open at all, many FCs etc. I will try to logcat your latest build tomorrow. Enough flashing for today...
[Nexus 7 Android Development] robgriff:
Mine is awesome, I've been trying many 7.0 and 7.1 ROMs and they all had the same problems, very slow with Kindle, restarts with YouTube, crashing and hanging with chrome, Firefox, ad free browser etc.... but since loading this ROM my grouper is running like it's new! Well done and thank you
[Nexus 7 Android Development] n3kf:
Dirty flashed it on my grouper. Your skill amazes me [MENTION=2188693]AndDiSa[/MENTION]. Thank you thank you. Running great.
[Nexus 7 Android Development] jolinnard:
Same here. Hope this logcat helps:

http://hastebin.com/imorocowat.vbs
[Nexus 7 Android Development] AndDiSa:
[MENTION=2002216]jolinnard[/MENTION] thank you for the log but as I do not have much experience with radio / radio logs, a standard logcat would help me much. I saw a permission error in the log, but I cannot individuate the origin. A standard logcat probably can help especially when there are some denial messages from selinux.
[Nexus 7 Android Development] shibadoo:
What I see in my logcat (looked for "radio" and "teleph%") are the following suspicious entries:

[ 12-09 09:24:10.305 210: 210 E/RadioService ]
couldn't load radio module radio.primary (No such file or directory)

Hi AndDiSa,

I am facing two issues, may be you could enlighten me on solving them.

1) wifi, connects and disconnects randomly.

2) while on lock screen, it takes sometimes almost five to six attempts to slide up, so that i can draw my pattern

am i missing something? any help shall be appreciated.
[Nexus 7 Android Development] teladog01:
I have this issue as well. It acts like it's waiting for you to slide farther up, but you're already at the top of the screen.
[Nexus 7 Android Development] shaggyskunk:
No issues with Wi-Fi connection on latest Grouper Build - BUT you could try reseting your Modem?

As for the Swipe Up to Unlock - I find that a tap and a Slower slide up works for me - If I swipe up too fast it doesn't work for me.

Successful installation of release 20181112 on tilapia

I have successfully installed the aosp_tilapia-7.1.2-ota-eng-20181112.ds.zip on my Asus Nexus 3g 2012 (tilapia), I also installed open_gapps-arm-7.1-pico and Magisk v17.3.

I installed your Android release, by using TWRP-3.2.3-0-tilapia, over the Asus original fully updated Lollipop. In fact the most tricky part was installing TWRP :)

During installation the initial OS configuration failed, multiple times (I tried with reboots), just during the user account selection. Using the suggested SetupWizardFixCrDroidNexus7.zip fix, fixed the problem, and I was able to complete the device configuration.

Finally:

My Nexus is back to life, is very responsive, browsing and playing movies are very fast...

I have also tried Skype and works like a charm, frontal camera works.

With official Lollipop my Nexus was simply unusable, u-n-u-s-a-b-l-e, I used to think that my beloved Nexus was simply too old for the new applications. I think now that Asus(or Google, is a Nexus) released defective OS versions for manufacturer-planned-obsolescence :(

[MENTION=2188693]AndDiSa[/MENTION], do you have a paypal account?

Last doubt:

For [MENTION=9350973]All[/MENTION], I have noted that MXPlayer uses the hardware codec A7-Neon, I have tried to install the Tegra3 driver, but it looks like MXPlayer is not loading it.

Is the Tegra3 hardware/features fully supported by your Android version? or am I forced to use the hardware like a generic A7-Neon?

Perhaps I miss something about MXPlayer configuration... don't know.

Thank you AndDiSa for your great release and for saving my beloved Nexus 7 3g

TWRP procedure

I wrote the procedure, I hope correctly, in my blog, I have tried to remind details.

I had problems understanding the fastboot unlock, and understanding that I had to use the .img TWRP files and the adb procedure. (I have one un-rooted Nexus 7)

My blog post

Perhaps I followed an sub-optimal path, but it worked.. there are different ways to perform the same task.
[Nexus 7 Android Development] Nexus7_tilapia:
Yea, You're right.

Years ago while using stock android, Tegra3 codec was installed in my device, but after using Mr [MENTION=2188693]AndDiSa[/MENTION] 's ROM, Only A7Neon Codec could be installed !

I do not know why MX Player recognizes my cpu as A7Neon instead of Tegra3!
