I can't get this to work on my tilapia. I followed this process exactly - just replaced all grouper with tilapia. I re-zipped it using both Windows Archive Manager and 7-zip. When trying to install it in recovery it just says "error flashing zip" without any further details. Using TWRP 2.8.7.0 for tilapia and verification disabled. What gives? :(

Edit: I'm an idiot, when zipping I didn't realise I was zipping the root folder and not the contents. Derp. Works now.
[Nexus 7 Android Development] qitt:
For me that's works fine.... Maybe broken zip ?
[Nexus 7 Android Development] stephendt0:
Damn you're too quick, I just edited my post before. Silly mistake. Need more sleep.

Some quick stats compared EXT4 and F2FS. Both done immediately after a clean wipe and re-install on my 32GB tilapia. Using Androbench for the stats. Excuse the lazy grammar :)

I am trying to build this myself, but I noticed one change that seems to be missing something:

https://github.com/GtrCraft/cyanogenmod_grouper/commit/e9cfb5b5ee993281d81719ecf0c51428ee17b048

The comment says "Updates for the new vendor repo structure" but when I check the TheMuppets repo for the binaries, there are no broadcom-vendor.mk, elan-vendor.mk etc. files.

From which repo are you getting these?

Hangout camera is working on video calls.

I don't know if camera is working on Skype.
[Nexus 7 Android Development] KawaiiAurora:
F2FS won't slow down your device.. It'll probably just corrupt it slowly..

[Nexus 7 Android Development] stephendt0:
Sample size = 1. Unless everyone is having issues with data corruption, i'll stick with F2FS. I've been using it for years on a range of devices with no issues. It could just be your NAND failing (which wouldn't surprise me on the Nexus 7, it has a mediocre NAND at best).

There's a new build up so I'll try that.
[Nexus 7 Android Development] KawaiiAurora:
Ok xD Not arguing with you but problems started after F2FS for me so my NAND is ok.

[Nexus 7 Android Development] Andiii:
my wife uses a nexus 7 which got all OTAs in a row within the last years without ever being clean installed since day one. Can't tell you how laggish this device is. Before i was going to trash it because its really unusable i now found this ROM and will give it a try. Which partitions should be converted to F2FS ? Data and Cache only or System also ?
[Nexus 7 Android Development] GtrCraft:
I dont recomend it but only data and cache
[Nexus 7 Android Development] Andiii:
will you update this ROM in the future? So is OTA working?

**edit**

i will then check with EXT4 and the "journaling off" first ;-D ....

**edit2**

good luck with your exams ...
[Nexus 7 Android Development] frankusb:
Here is my 2 sample anecdote.
[Nexus 7 Android Development] phrozenstare:
to the people thinking F2FS is faster its not worth it. just get an app that will perform the TRIM command every few days or so and you will get the same performance using ext4
[Nexus 7 Android Development] JoeF2:
Even with ext4, it feels to me that this ROM is faster than the CM12.1 I had on the tablet before.

Is marshmallow force encryption disabled in this ROM?

Thanks.
[Nexus 7 Android Development] Sage:

[Nexus 7 Android Development] GtrCraft:

One thing: my PC (Win10) don't see my Nexus. What must i setup?
[Nexus 7 Android Development] howasparty:
As I don't know how to compile it for Grouper, is there an installable zip for it?
[Nexus 7 Android Development] Sage:
It needs to be added to the kernel and recompiled as a flashable zip.. Ideally would be nice if it was added to the this kernel within the ROM. If not someone might be nice enough to add it for us a separate flash. :)

How is battery life compared to 5.1.1?
[Nexus 7 Android Development] seegs11:
Hey everyone I'm really in need of help.

I flashed cyanogenmod's v 13 rom coming from 4.4.4. In cwm it said may of lost root, yes to fix? I wanted to go back but it booted anyway. Now I'm stuck on this ROM without any Gaaps, and when I go to boot into recovery to flash the gaaps, it only shows the Google logo so CWM appears gone. I've also tried downloading playstore and ROM manager via the Web and it force closes when it goes to download.

I'm I doomed or is this fixable?
[Nexus 7 Android Development] paolocorpo:
I am not sure to have understood well ... ;)

I am suggesting to you:

Boot in fastboot mode

Flash recovery custom

Using the Volume balancer switch to recovery and boot into recovery using pwr button

Flash the gapps

Done
[Nexus 7 Android Development] pavik62:
Why don't you put TWRP? https://twrp.me/Devices/
[Nexus 7 Android Development] seegs11:
Thanks for your reply, how do I boot into fastboot mode to flash a recovery mode? Power and volume down only gives me restart bootloader, recovery mode or restart.

CWM is gone when I boot into recovery mode. Sorry I haven't done this in years and decided to go back and root my tablet.

[Nexus 7 Android Development] paolocorpo:
I was not suggesting this ..

Please let have a look of my pevious post #108
[Nexus 7 Android Development] aaopt:
Before you select start or recovery mode, you are in fastboot mode. Now you can connect to a PC with fastboot installed and push TWRP or CWM to the device. Instructions here -- scroll down to "fastboot install method." But you don't need to "adb reboot bootloader" since you know how to get to the start/recovery/etc menu.

Force encryption is only for new devices that come with factory-installed Android M.

But you can of course enable encryption yourself. I always do that. It works fine with this ROM.
[Nexus 7 Android Development] :
cant download any files in default browser, browser force closes
[Nexus 7 Android Development] Sage:
If coming from 4.4.4 to 5.x or 6.x then i believe you will have to upgrade the bootloader as well or you will bootloop. So once you have got TWRP or CWM recovery back on. You should also flash the bootloader through fastboot.
[Nexus 7 Android Development] seegs11:
UGH this is so frustrating. So I downloaded SDK manager and was going to push CWM through CMD command, however... the bootloader is locked, so I can't push the recovery through. No idea what do to now.
[Nexus 7 Android Development] Sage:
Strange if the bootloader is locked i have no idea how you ever had a custom recovery. Pretty easy to fix just run "​fastboot oem unlock​" then follow the instructions on the tablet. Once complete you will be able to push the recovery. (Hit thanks if i helped :))

---------- Post added at 11:52 PM ---------- Previous post was at 11:51 PM ----------

oh yes by the way you dont need the whole SDK. Just get the "Minimal ADB and Fastboot" only a couple of MB. I should add unlocking bootloader does wipe all the data (i believe).

how do i flash the rom in a row? i would like to wipe full - including a "format DATA" in TWRP

1. wipe factory reset and after that format DATA

2. connect to PC and copy files to N7 (ROM zip, GAPPs zip, Journal_off script zip)

3. flash ROM

4. flash GAPPs

5. flash Journal_off script

is 3 - 5 correct?

Is root already included or do i need to flash supersu too ?

Wow! Finally got around to installing this on my nexus 7 (grouper). It's wonderful. I had cm12.1 on it for quite awhile, but it was so abysmally slow, that I'd finally gone back to cm11, which was a bit better. But, so far, cm13 is marvelous! Just flies along. When I touch an icon, it actually responds, instead of just sitting there for half a minute. So, thanks hugely for the work on putting this together.

Still looking really good. I haven't gotten the gradual slowdown that seems to have plagued this poor tablet for so long.

Ahahahah, just found a weird bug.

Was syncing some movies via plex over to my N7 for an upcoming trip, and when i went into Settings -> Storage & USB, I'm show

9.69GB

Used of 13.45 GB

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

Apps

2744 PB

...

2744 ... petabytes?

(click)

Plex is using 2744 Petabytes?!

Now, plex app says it's only using 7.4GB of storage, which seems more likely, given that it's only a 16G N7.

Not sure why the system is reporting in Petabytes though.

Tilapia Wakelock

Thank you very much for helping us tilapia users out.

A question to the other Tilapia Users. What "mileage"/runtime do you get with this fix (Jan 12th build) if the tablet is not used? For me it is still significantly < 2 days.

With CM 12.1 and the any-kernel from vorcers from here (sorry it is on German I could *not* find a corresponding thread by vorcers - though user does exist - on xda-developers):

http://www.android-hilfe.de/thema/k...id-os-bug-baseband_xmm_power-wakelock.666283/

I got a runtime (standby only) of > 4 days with my tilapia at least if I set the timeout to 0 (the kernel from the website does allow to set the timeout value at any time via /sys/module/baseband_xmm_power/parameters/bb_timeout). I have to mention though that I only reached this value *after* flashing the radio.img from the zip of the nakasig-4.2.2.

https://developers.google.com/android/nexus/images

Before that I had flashed a full to stock 5.1.1. including radio.img. This in combination with afterwards flashing CM 12.1 also resulted in < 2 days runtime. So it seems the code inside radio.img does also play a role with the wakelock-behavior.

[Nexus 7 Android Development] ak_hepcat:
No, it was definitely a ROM problem, and only via the Settings->Storage link. "df -k" showed things correctly as expected, because the issue

lay in the way the settings app was parsing app data usage, and triggering a bug there. Not at the filesystem level, which would have shown

up in other areas.
