[Nexus 7 Android Development] Charles IV:
as to formating data, i doubt it would help, but there is a chance, but if you attach a logcat, we can find out what's causing it to crash.

also, does it crash at a specific time, or just constantly as soon as (or even before) it loads?
[Nexus 7 Android Development] Flounderist:
I get several errors from Iwifimanager and from play.googleapis.com.

Trying to get a .text file. Sorry never logged before
[Nexus 7 Android Development] Charles IV:
possibly to do with gapps, but i think wifimanager may be the problem.

When you flashed the rom, did you select the rom to flash, and then add the gapps pico to the zip queue thing in twrp? or did you do them separately?

also about the text file for the logcat, if you're using the built in android one (i think there is one), i'm not sure where, or if a txt file is created, but maybe if you use an app from the play store, they may tell you where and if they create a text file
[Nexus 7 Android Development] Flounderist:
Here is a logcat of recent activity.

Flashed 0423 build with OpenGapps PICO 20170504 + txt file.

I wiped cache+dalvik+data+system, then flashed ROM + Gapps on TWRP alltogheter.

Setup is crashing just after selecting language.
[Nexus 7 Android Development] Flounderist:
Ehi! I was messing around the screen during setup wizard and quick setting pulled down! I entered setting menu and I connected WiFi and all is working fine now!

[MENTION=3729448]aaopt[/MENTION] I was looking through [MENTION=2188693]AndDiSa[/MENTION]'s LineageOS device tree, and I noticed a few things.

In full_grouper.mk, AndDiSa had restricted languages to gain space in i assume system, I wondered if you had seen this and decided it didn't save that much space after all, or not.

The other think was PRODUCT_MODEL is still set to CyanogenMod on Grouper, not LineageOS
[Nexus 7 Android Development] DrTofu:
I noticed just a minor bug: if I try to share screenshots in my gallery from the Facebook app, it won't recognize them

EDIT: Fixed: I just had to go through the gallery, change the background so to give the gallery all the permissions and Facebook got fixed

But otherwise, this rom gave new life to my Nexus 7
[Nexus 7 Android Development] fraddy91:
Today i did try to format F2FS on my nexus 7 grouper, all data was restored successfully with flag no format without any problems. F2FS installed on Cache and Data.

Androbench results is in the attachments, tablet started to work superfast! Results is better than N7-2013. I'm really happy now, I had to install f2fs a lot earlier.

Low Memory Killer needs to be ultra aggressive to avoid out of memory freezes/crashes

Thanks! - this made the 20170507 ROM run almost perfectly for me. Before I had set the low memory killer to be this aggressive (using Kernel Adiutor), I would eventually get freezes and crashes presumably due to memory not being freed fast enough. I even go higher on killing visible (non-foreground) apps - 173mb instead of 150mb. Stupid Candy Crush is such a memory hog, I still try to swipe it out of the recent apps list when I am done playing.

One symptom of the out of memory problem I kept seeing was that my Photos wallpaper would be reset to the default pattern.

---------- Post added at 06:41 PM ---------- Previous post was at 06:27 PM ----------

I gave up on F2FS on Nexus 7 2012 32GB (grouper) because it kept showing file system corruption when I would try the TWRP file system repair utility. The TWRP (version 3.1.0-0) file system repair utility [Wipe - Advanced - Repair...] would always show /data corruption after the ROM is installed (any ROM I've tried). The repair utility works without errors right after formatting, but after the ROM and Gapps are installed and used a little bit, the repair utility shows errors. I never get any repair errors using ext4 partitions. This happened with TWRP 3.0.2 too.
[Nexus 7 Android Development] :
+1

For me the same
[Nexus 7 Android Development] cameraddict:
I'm glad this worked for you! I also use Chainfire's Recently app with the following settings:

age Limit 6hrs

Entry Limit 4

Google Searches 2

Hide Settings

force remove tasks Set

force remove documents Set

This combined with the Low Mem settings keep things more or less functional for me. Though, I am still using an older Oct OS. I may have to try LOS now!

Yep, I think the memory in this device was the lowliest pos that Asus could source. Absolute s h i t e. I had the same issues with F2FS.
[Nexus 7 Android Development] aaopt:
So here's a new build 20170609 for testing. For me it seems slow, but YMMV. Curious to hear how it works for other people.

This build includes June security updates, plus Lineage changed wifi to be on by default to avoid crashes in the setup wizard.

In his AOSP build, [MENTION=2188693]AndDiSa[/MENTION] has switched CPU governors for the kernel from interactive to intelliactive. He says it gives better battery life at the cost of a small performance hit. Just for fun I am providing two boot.img files so you can form your own opinion... at least this time. They have the same kernel build -- AndDiSa's current -- with two different init.grouper.rc files specifying settings for interactive and intelliactive respectively. After the ROM is installed you can switch back and forth between kernel governors by flashing either boot.img file directly from TWRP. (If you don't install a boot.img on top, my current ROM build uses intelliactive.)

[No DRM changes on my side -- don't get your hopes up for this build in that respect.]

Seems about the same to me. I haven't tried any benchmarks on it, so can't give any figures, but subjectively it seems about the same as the previous build
[Nexus 7 Android Development] adamsson6:
Hi everyone, thanks to the developers for lineage os on this old nexus 7 !

I tested it 2 days and it's working almost perfectly.

The only thing weird i discovered is this :

When the light turns in night mode ( screen temperature under 6500k) the tablet become laggy. But when i but it manually to 6500, it become smooth ! I don't understand why, but it's the only one problem i have encountered so far.
[Nexus 7 Android Development] Charles IV:
So you have this as well, I noticed it was laggy when the night temperature was enabled, but I assumed it was too do with other stuff, and didn't test it.

I'll do a bit of googling, and see if all devices have it. I'm not sure whether there's a fix to this problem.
[Nexus 7 Android Development] paolocorpo:

Installed 20170609 a few days ago. I don't see any noticeable difference in performance. I don't know if there is any battery gain because my battery is already very exhausted.
[Nexus 7 Android Development] kjlw99:
I so miss CM, that I might have to try this

trebuchet started freaking out, so I did a reset a few days ago. No luck, so I did a wipe to stock lollipop, but like KK after that I had problems getting logged into Google. I later tried a CM_nightly from archive.org, and just about the time I was about done tweaking; the trebuchet became unstable AGAIN.

So now I'm back on lollipop(rooted). It never ocured to me until after I got logged into Google on lollipop, that there might be a lineageOS build available. This is a strong plan-B for me currently in case stock ****s up somehow.

My only question is do you have any idea, when lineageOS or your builds might get the stable tag?

Thanks,

kjlw99
[Nexus 7 Android Development] freebazee:
Nexus 7 is rebooting itself every time the screen turns off ... it's in a continuous loop (restarts - Sleeps - restarts again). Works fine if I keep on using it.

My Nexus 7 was rooted on 4.2.2

Here's how I installed lineage-14.1-20170503:

Factory reset

Installed TWRP v3.1.1

Wiped everything

Installed ROM and rebooted (I was stuck at setup when I tried it with Gapps installed)

Have I missed any steps or do I have to do some extra steps as I was on 4.2.2 stock?

Thanks
[Nexus 7 Android Development] sunscape:
Install with the first release by OP. Update to most recent after setup.
[Nexus 7 Android Development] dooderooni:
I installed the new build on the 9th via a clean install with data and cache formatted to F2FS. It seems as snappy as previous builds and I haven't noticed any issues with F2FS so far.

The only slightly annoying thing is that the wallpaper reverts to stock at seemingly random times and no amount of fiddling with my Google settings will allow the weather widget to display the weather on the Pixel Launcher (it is stubbornly stuck displaying the date). I've had the same issue on other ROMs though so I don't think it's just a problem on Lineage. The exact same settings and permissions on my Moto phone display the weather correctly though.

Is anyone else having issues using the Pixel Launcher?
[Nexus 7 Android Development] Charles IV:
I recommend nova launcher, and you can then import your layout, or set it up new, just like pixel launcher, but with more flexibility.

I might try it though, see if i have the same problem
[Nexus 7 Android Development] prem4425:
I have nexus 7 2012 wifi model tablet. Right now it has android 5.0 OS. it is every slow. So i am planning to change the OS. Can you guide me how to change OS and I need to make my tablet works fast with new / old OS. I don't know even how to take back up current ROM. If anyone give me URL /Link to change my OS. It will be helpful.
[Nexus 7 Android Development] Charles IV:
I don't know of any links, but try searching the whole of XDA, you'll probably find a few threads.

Also, Google gives a guide to flash back to stock on their website, but I don't know if it works for custom roms.

Once you have read those guides, read the op of this thread, so you get the details, and zip for the rom.

I would tell you, but it would be a bit long, and you would find it elsewhere.

Take an ear stick ( to clean ears) and spray it with a window cleaning spray, just a little bit.. and clean the stereo jack with it.. It helped me numerous times with same problem..
[Nexus 7 Android Development] robeirne:
My first post on this forum. For the last couple of years I have been successfully running SlimKat on my Nexus 7 but thought I give this a try.

I successfully installed the ROM and like it except that I cannot get any file manager to work. When I start the one that comes with the ROM (Files) I briefly get a message "MTP Host has stopped". It then gives access to Images and Videos but trying to access the root directory or Documents I get "Can't load content at the moment".

I tried other downloaded file managers.

OI File Manager allows me to see the root directory but all folders are empty. It does not request request root permission.

Total Commander did request root permission which I granted. It allows me to navigate to / and I can see the contents of most of the folders except for the storage area. When I try to access sdcard or /storage/emulated/ I get "Error - Cannot open file/folder! emulated" (or sdcard).

Is this a problem others are having? Is there a simple solution I cannot see?
[Nexus 7 Android Development] Charles IV:
have they been given the correct permissions?

also, all those with tilipia, I've found this. It's not by aaopt, so root isn't build it, but it is still los14.
[MENTION=3729448]aaopt[/MENTION] I don't know whether I'm being rude doing this or not, but a few people were asking if you would support tilipia
[Nexus 7 Android Development] DrTofu:
I've upgraded yesterday to the new version.

My battery is new, I replaced it a couple of weeks ago because the original one died, stock replacemnt.

I'm using it, I can already notice that with light use in 9 hours I'm at 86% with 2 days to go.

Seems there's actually improvement
[Nexus 7 Android Development] robeirne:
I have enabled Root access in Developer Options and Total Commander is listed as having root access. I have also ticked "Root functions everywhere" within Total Commander. I still get the error that I can't open sdcard storage. Is there something else I should do?
[Nexus 7 Android Development] aaopt:
I don't mind if other people post builds. We can all learn from each other. But you'd better ask [MENTION=4598799]hazzer[/MENTION] before you start posting links to his builds as he may not be ready to support them just yet. When I tried his grouper build a couple weeks ago it didn't boot for me. Hopefully it was a temporary thing. In any case he does have some ambitious ideas and I look forward to the time when he is ready to post them himself... Presumably in his own thread(s).
[Nexus 7 Android Development] Charles IV:
Ah, thanks, I was trying to find him everywhere, but couldn't find him.

I'm using his build right now, and it feels a lot snappier, but that's because I wiped data and haven't restored it.

---------- Post added at 12:06 PM ---------- Previous post was at 12:05 PM ----------

What about normal permissions, like access to files (you can manage them in settings)
[Nexus 7 Android Development] robeirne:
All fixed now. You were write about permissions. It appears SuperSU was not properly installed so once I redid it was fine. I still don't know why I could see the sdcard folder though.

Many thanks for you suggestion.

Fantastic ROM, flashed it on my tilapia (don't need 3g) and it runs unexpectedly smooth and battery is great too.

Anyone who has the mtp host stopped working bug, if you don't use mtp just disable the service via a service and app disabler from the play store (dirty fix I guess ?)

What's the best file system to use with this? F2FS

What about the Pixel Launcher? Any reason that isn't included or is it because I used pico gapps or something? Yup - AROMA with minimal inclusions is possible to get pixel launcher.

[Nexus 7 Android Development] Quigongentoo:
I'd like to thank you for this ROM, I recently got to fill my house with Sonos speakers using my hotel points I've accumulated in my travels (yes I saved that many ?) (yes I travel a lot ?). In doing so, I dug out my old Nexus and loaded this up. I run only the Sonos Controller App on the old girl and pin the screen. I can then hand it to anyone who wants to listen to something of their choice. Basically, its now a Sonos remote! Runs great! Very nice way to reuse some old but still functional hardware. Thanks again for your time and effort, it doesn't go unappreciated.
[Nexus 7 Android Development] pieceofphil:
That is the only bug with the mtp service FC, you have to force close (tweak setting to make long press back close an app) the app after you gave permissions to the local memory, for the app being able to write on the intern memory.

Don't know if this is only for people with f2fs system because nobody mentioned it before.

Nonetheless, my Nexus flies like in its old days (had temasek 4.4 kit kat build running on it before, the only version the Nexus was still usable) and performance wise they are up par.

[Nexus 7 Android Development] dlfuller:
Thanks for the updated lineage-14.1-20170609 ROM. It's working well.

I continue to reliably use my old Nexus 7 for a wide variety of operations and have a suggestion that works for me. It might be useful to others.

I keep the free Cool Tool app enabled all the time with a small menubar display including CPU, RAM, and network activity gauges. They offer great feedback during lags. And, the most useful is for when some activity pegs the CPUs, I simply wait for them to settle down before starting my next step. Patience.

Interestingly, maximum memory or network activities seldom seem to be an issue. For me, it is activities where all four CPUs are maxed out. Google Keep in particular with its launching, syncing, and display.
[Nexus 7 Android Development] pieceofphil:
Still the battery life is great as far as I am concerned..

Should this ROM (20170609) work with F2FS as the filesystem type for the /data partition?

I am using TWRP 3.1.1 and have a N7 2012 8Gb and I first changed the type using the 1st part of this guide

https://xdaforums.com/transformer-tf700/general/guide-convert-data-to-f2fs-twrp-2-8-t3073471

to convert the /data partition to F2FS.

When I tried to flash the ROM after this, it gives me the error in the photo

EDIT: My mistake was to not convert /cache to F2FS also
[Nexus 7 Android Development] meatfest1974:
This is a great ROM!

I nearly sacked my Nexus 7 when they stopped updating the unofficial 4.4.4.

I hope this isn't redundant to say, but I've seen some forums here that give a few hints on keeping the Nexus 7 fresh and fast!

Install fstrimmer from the Play Store and trim often, enable Developer Options and max out the Background process limit to 4, and flash a .zip in TWRP to disable journaling (search the forums for this one).

EDIT: Download and flash the disable journaling .zip in TWRP from the end of the first post: https://xdaforums.com/showthread.php?t=2280496

Believe me, I didn't know any of this, so thanks to those threads, posts, and forums for the valuable input!

[Nexus 7 Android Development] abhifx:
i can confirm that i have tried disabling jounalising and there seems almost no effect. i can still hand my tablet if i want to.

what i have observed is, anything browser related can bring down the tablet almost to its knees immediately. just start a browser and run a site, run maps and the system goes heywire.

all problems seem to stem to probably webview usage. also gapps play a huge role as without it tablet remains snappy.

this needs more digging.
