Now that kerbel 3.4 is in beta stage.. can a new ROM with this kernel (and hal, blobs etc) be compiled?

P.S. obviously this post means requesting a build with new kernel :P

Can I dirty flash this over cm11?
[Nexus 7 Android Development] jjsan:
of course you can, but it wont work
[Nexus 7 Android Development] aaopt:
I'd say it can't hurt to try, as long as you start with a full TWRP backup of system + data so you can go back if it doesn't work out.

So, I'd back up system + data, then wipe system + cache + dalvik, then install this ROM + pico gapps.

If it doesn't boot, go back to TWRP and restore your backup. But more likely it will boot, but will have a few apps which crash on startup, perhaps repeatedly. If you "clear data" for those apps, you should be all set. If it's something like systemui, it might be easier to clear the app's data in adb.

(Just did this on a different device, admittedly only going from CM12.1 to CM13, but it shouldn't matter so much.)

If any of that description scares you, don't try. But if you are comfortable with TWRP backup and restore then it shouldn't hurt to play a little-- you can always go back.
[Nexus 7 Android Development] wileout:
Why wouldnt it work? If i wiped system and not data?
[Nexus 7 Android Development] jjsan:
its easier to do titanium backup and restore data after reinstall.

it may work but I dont think it will.

but give it a try and let us know
[Nexus 7 Android Development] wileout:
I didnt even think of tb duh lol
[Nexus 7 Android Development] 9Lukas5:
Updating from 12.1 to 13 worked perfectly fine (was even said by cm that it will work)

From 11 to 12.1 if I remember correct it was only the clock app to clear the data^^

Issue with last build

Hi all,

clean install last build + open gapps pico = error 70 ... not enough space in partition system :(

Any solution ?

@ GtrCraft,

thank you to maintain this ROM ... I appreciate your effort :):D;)

For me it seems to work, that i downloaded aroma gapps, it has graphical installation, i didnt choose anything (i just uninstalled some biult in app) and it didnt have error code 70
[Nexus 7 Android Development] aaopt:
Aroma is really neat, but it's a little ironic to download a 10x larger package in order to be able to install less.

opengapps is highly customizable. You can put a .gapps-config file in the same folder as the pico zip, with commands to control what it installs and also to remove some stock apps to make room. So just now I had one with these lines:

# stock removals
Browser
CMAccount
CMUpdater
Email
ExchangeStock

and it seems to have installed OK. I'm still in the initial boot but via adb I see 87MB free on /system.

[Nexus 7 Android Development] pixelated:
The last Snapshot from 2016-08-16 has a rather strange bug on both of my devices (grouper and serranoltexxx) - it has poor performance when Battery Saver mode is OFF. Once I turn it ON everything is back to full speed. So it is reversed somehow.

Snapshot 2016-08-20 is available since yesterday for serranoltexxx and it has fixed this behaviour. Could you please post an updated Snapshot for grouper, too?

Thank you very much in advance! I really appreciate your work, GtrCraft, for keeping our beloved but troubled little tablet alive.
[Nexus 7 Android Development] Licaon_Kter:
OMFG, that fixed the slowness, thank you for the tip.

Now, I do see that once I switched it to 15% the performance is ok again, but I can now switch it to Never and it stays the same, strange, I guess it might have been triggered once in the past and got stuck there, I'll test a bit more once battery levels go down to <15%.
[Nexus 7 Android Development] tj13:
There is not a lot of room. The package you are able to use might not replace all of them. My experience says you could have a really flaky device if you don't start clean. But it's worth a try. You can still do a clean install later. I have.
[Nexus 7 Android Development] Hungry Garfield:
Perfect recipe for my nexus 7!

I had installed the official cm 12.1 and it wasn't stable. Restarted and choked intermittently.

Currently on this ROM and it works flawlessly! Thanks to you. :good:

CM13 + F2FS in cache and data partition. Apparently, I only found out about F2FS pretty recently and the difference is big on nexus 7.

So, thank you and great work!!
[Nexus 7 Android Development] sancamcal:
Hi all,

i have some questions about this amazing ROM. Maybe between all can solve and could be useful for everyone. Lets start:

1. I can flash journalist script and Parrotmod together? as i see in official Parrotmod post, isn't compatible (Disable journaling zip (it conflicts with my script, and doesn't improve performance))

2. i put any limit on background process? on this post said taht use 4 but in official Parrotmod.. (Don't limit background processes, it might even make the tablet SLOWER. As of version 2016-04-30, the installer script removes this setting from build.prop automatically.)

3. How can i know if both of them are applied?

3. How can i fix the slowcharge bug?

4. How can i config the voltage to try undervolt?

5. What configuration is optimal on Performance Control app?

6. Worth to OC for the increment on battery waste?

7. Maybe kernel config can make useless parrotmod? again, in parrotmod official post (PLEASE disable IO scheduler/RAM/read ahead tweaks in kernel apps. They override ParrotMod's meticulously optimized settings.)

Thanks in advance!!

And another yep for me.

Just 2 things you should watch:

* do not enable LiveDisplay since it will lower performance too

I'm not asking for ETAs, but just wanted to ask what everyone wishes, will there be nougat support for this device ?
[Nexus 7 Android Development] GtrCraft:
Not from me
[Nexus 7 Android Development] JoL1hAHN:
I can't find any statement posted by GtrCraft on this thread about this ROM being abandoned though, or did I miss something? If so... well it'd be a pity but hey, he spent his own free time till now to prepare a great build of CM 13 for our poor grouper so it's not like I can't undestand if he decided to move onto something else :)

That said, the other day I flashed CM 13 0816 on top of an unusable KK 4.4.4 (stock + root and custom kernel) and so far I'm impressed by how my Nexus 7 seems to be revived, there are still some hiccups and lags every now and then but it's not terrible. I've never dared to update to stock LP 5.0 because I read that it's an even worse and more frustrating experience than stock KK 4.4.4 in terms of lag and I avoided the official CM 12.1 for this device because I read it's kind of bad, so I can't thank enough GtrCraft for preparing this unofficial build of CM 13 for the Nexus 7!
[Nexus 7 Android Development] sarys693:
Cant get any of the Gapps installed I get error 70 when try to flash it. can some one help me with that?
[Nexus 7 Android Development] Ahkah:
You should consider additionally installing Parrotmod. Mainly this is a script run at boot time which changes some system parameters and makes the device generally faster.
[Nexus 7 Android Development] PukeStinkLikeRye:
Thanks [MENTION=5293805]GtrCraft[/MENTION] for keeping this ROM as current as you have!!!
[Nexus 7 Android Development] JoL1hAHN:
Thanks for the advice but I'm already using both ParrotMod and DC-Kernel and the data+cache partitions are trimmed twice a day. This setup generally works well for the Nexus 7 but the device starts showing some lags during certain operations (mostly I/O related) when the data partition is about 80% full which is consistent with my previous experience with the stock KK and other kernel tested with it. Everything considered, I'd say it's actually kind of a miracle that the device is still usable under these conditions when the main issue is hardware-related (that is, the damn slow NAND flash chips for our Nexus).
[Nexus 7 Android Development] hanschke:
no cm14 thats bad but will you give us a latest cm13 build?
[Nexus 7 Android Development] eNVy:
[MENTION=5293805]GtrCraft[/MENTION], Can we expect one more build, CM has made a lot of changes to the theming section of the ROM.
[Nexus 7 Android Development] aaopt:
Those kinds of changes can make updates a lot of work. Around the time of GtrCraft's last update they added a new charging screen and it would not build for grouper due to missing resources of the size we need. I haven't tried to build since then but it wouldn't surprise me if theming changes have similar issues.

Perhaps it's time for someone else to step up?
[Nexus 7 Android Development] GtrCraft:
No, my time with grouper is done
[Nexus 7 Android Development] JoL1hAHN:
[MENTION=5293805]GtrCraft[/MENTION] then you might want to consider modifying the original post to reflect the state of this ROM just to avoid having the same question asked all over again in the future. Thanks for your work!

error 70 is a space restriction,

make sure youve downloaded the pico apps,

and try one if the smaller builds....the smallest I found was 243MB, it was small enough to allow me to install gapps.....

(https://www.androidfilehost.com/?w=files&flid=46193)

now that I know, Ill start flashing larger versions. The last version is a massive ~40MB larger than the smallest.

I have no idea how anyone got the last build and gapps to work.... but the combo of pico and smallest build >seems< to work for me.

I also had fs corrupted on CM12@grouper with f2fs:

http://forum.cyanogenmod.org/topic/92939-f2fs-support/#entry503057

This bug was fixed some time later, but I never returned to f2fs on /data. Only /cache was f2fs, but now I'm all-ext4. F2fs do it's best on writes, but i have no so much writes on my devices.
[Nexus 7 Android Development] KawaiiAurora:
I would suggest scrapping F2FS altogether since it's caused me problems on various ROMs (both AOSP and CM based). SlimKat and SlimLP were ok... This ROM could've corrupted the FS but F2FS is very flaky. ext4 with Gtrcraft's instructions is much better.
[Nexus 7 Android Development] aaopt:
On the other hand Motorola ships it on their devices. Can't be all bad.
[Nexus 7 Android Development] KawaiiAurora:
It might be OK on other devices but on the N7, it's been a pain for me. Well, if you look at the facts, you can conclude that F2FS is pretty unstable. I even had to erase userdata via fastboot since recovery didn't start since /userdata was very crippled after using a ROM with F2FS

Journaling post 2

Been using cm-13.0-20151227 for 2 days now, and think it superior to cm12.1. Only thing I found not working is screencast. Tablet hangs when it is disconnected from chromecast. Individual app casting (netflix, youtube, etc.) work fine. I used this "jubie_test_script_remove_journal.zip" to disable journaling before post #2 was changed. Is there a way to verify it is disabled? The link to it in post #2 gives a 404 error, and I don't understand the instructions in the second link to disable journaling.
[Nexus 7 Android Development] Licaon_Kter:
In a terminal (normal boot or in recovery):

* su

* mount

(take note of paths APP/CAC/UDA or even /block/dm-0 for cache, system, data)

In the feature list usually the first is has_journal, if you don't see it there, it's ok.

Hi guys,

"patching" for tilapia as Denpasar described above works like a charm. Flashed my tilapia/nakasig successfully with versions 2015-12-27 and 2016-01-01. As described also for my device only the pico-variant of gapps fitted in afterwards. As expected GSM is not available.

Without any further apps installed predicted run time - without using it for a couple of hours -> standby - increased to 9 days instead of 5 (for stock 5.1.1). So in general the advanced energy mechanisms of marshmallow seem to work. Unfortunately after installing apps this is significantly reduced to 1-2 days (even "only" chrome). However, I get the feeling that this might be some kind of special error with my device as I experience this with other ROMs (stock 5.1.1, "stock" 6.0.1, CM12) as well as trying all the "usual" tricks I found in my search (auto-sync off, WLAN off, airplane mode....). Had a little hope CM13 could possibly somehow "fix" this. Will investigate a bit further and otherwise return my device.

Nevertheless, great piece of work, thanks!

It's probably just me, but I downloaded the 03 JAN edition of the rom, did a full re-format of all partitions, converted to F2FS for data and cache, installed, booted, checked permissions, rebooted and flashed pico gapps, but can't escape the force-close errors once-ever-10-seconds. I was able to slowly navigate into the permissions and make sure that google play/service, and the setup wizards both have all the permissions, but it's still FC'ing.

So, i rebooted into recover, did a factory reset, and...

Now it's not FC'ing.

So, just for future folks who may run across this, if you're still FC'ing after setting up permissions, a factory reset should clear it right up.
