The 2nd post doesn't refer to deleting the system partition, he means "clearing" the system partition, IE: using wipe in TWRP

" I suggest you to erase the system partition completely before applying the OTA package"

screenshots

Hi again !

how to take screenshots with this android aosp 7.1 ? tried traditional vol + power without success, any way to enable it or any app that add this feature in a handy way ?
[Nexus 7 Android Development] mikeataol:
Power and Vol - works for me, it sometimes takes a couple of tries to get the timing perfect.

(edit: it's Vol down)
[Nexus 7 Android Development] fsw_informatrix:
Yes, it's Power + Volume Down, but it can really be tricky ;) you have to start to press Power first and then very quickly Volume Down... It's hard to get it right each time!
[Nexus 7 Android Development] fsw_informatrix:
You can also see here how it is on mine. System is small on our devices, but data should be 16 or 32 GB, according to your model...
[Nexus 7 Android Development] adrenochrome25:
ok, thanks :) i tried it befor but without success, it seems it's volume down and power at the same time (one to early and you get power menu, the other and you get the ..volume display) and you must keep them down like a long press. A real pain with the shape of this tablet's borders. I ended up installing "Screenshot Assistant" which take a screenshot by only long pressing home menu button :)
[Nexus 7 Android Development] :
Yes, but not recently. It was a problem for me a few months ago. Have you got the latest release of the ROM?
[Nexus 7 Android Development] danibus:
hi folks, you were right, I'm doing all again. I just did all wypes and formatting options XD

Now lot of empty space to use, almost 11GB free, thanks for your help
[Nexus 7 Android Development] Flounderist:
Yes. It also charges very slowly and sometimes the device shut off suddenly.

The weird thing is that consumption is ok.
[Nexus 7 Android Development] AndDiSa:
Looks to me as your battery is showing it's age ... :)
[Nexus 7 Android Development] :
It's not (ime) quick to charge but I honestly don't find that a problem. Like [MENTION=7193743]Flounderist[/MENTION], the consumption is good. Well, better than other ROMs that is. Of course, I'd like it to last longer but, given it's age, I really can't complain. It runs smoothly and has good response which, given it's 8 years old, is pretty darn good :)
[Nexus 7 Android Development] Flounderist:
I'll try to open the hood and to unlink/relink battery to motherboard.

If no luck, I will get a replacement, it's just a few bucks.
[Nexus 7 Android Development] breaktheblock:
I'm having trouble with web browsers, duckduckgo and privacy browser both download on fdroid. Duckduckgo crashes after entering a URL and privacy browser crashes on startup. These were both downloaded using fdroid. Is there a way I can debug why these are crashing? Or any tests or other things I can try?

It's probably a bigger problem with the while tablet but if there is anyway I can trace and report that would be good.

Edit: I have a logcat app called 'logcat reader' and that keeps crashing, I wonder if I have a hardware problem, is that possible?
[Nexus 7 Android Development] danibus:
Enter your google account.

Play store and download web browser you want.

Delete Google account.
[Nexus 7 Android Development] HTCDreamOn:
That's very odd. This is just a clean install of the ROM with no GApps, etc.? If you want logs best bet would be to plug your N7 into your computer and use adb to get the logcat. You just run

adb logcat

or

adb logcat > ~/<whatever path>/log.txt

if you want to save it to a file.

EDIT: What about file system? Are you on ext4 or f2fs? (follow the blocks check advice below).

... This is very unhelpful. Don't do this (you couldn't if your entire aim is to not install GApps anyway).
[Nexus 7 Android Development] adrenochrome25:
Maybe you could try a browser like Firefox first, just to check if it run as expected like for other users. I don't know very well the 2 you mentioned but they could perhaps just have not enough ram available depending on their engine.

Or you could try "e2fsck -cfv partition" from adb in order to check for bad blocks in eMMC storage

I had similar frustrating problem with AOSP. Finally with this ROM and gapps, I was able to install Google Chrome and in the preference specify a d/l folder, then I could d/l stuff.
[Nexus 7 Android Development] abhifx:
Great Post!

also, just saw amazon kindle HDX CM14.1 official support, that tab should be dirt cheap and mighty powerful for your needs.
[Nexus 7 Android Development] AndDiSa:
[MENTION=7927633]EveningStarNM[/MENTION] Thank you very much much your post, I really appreciate it because it describes exactly my situation and the reason why I started to build from the AOSP by myself.

I didn't use encryption of the device yet because I always had the fear that I was not able to access / to recover the files e.g. when the device is messed up. In recovery you probably then have different / no keys to decrypt, etc. Especially TWRP for Grouper is a bit old now and does not fully support the new file based encryption (which is now standard in 7.1.1 and so there is no longer an option to enable / disable it). In addition I do not know how the Tegra3 performs with encryption. I guess there is no hardware support and so performance will drastically decrease. Nevertheless I'll try to address your (and all the other) findings to get most out of our beloved Nexus 7.

[Nexus 7 Android Development] UCHIHA:
Dev, first i really appreciate for this great rom.

its really really awsome for daily use.

but,

referenced from this note : opengapps Notes for Android 7.x

can you add WebviewPatch from opengapps,,, pleaseeee?

because i always use stock opengapps (with gapps-config.txt) and replace all app with google version.

i always face google play service has stopped error if i replace stock webview with google version.

so i cannot login to my google account.

until that patch included, i use stock webview.

hope that thing will come.

thanks dev.
[Nexus 7 Android Development] AndDiSa:
[MENTION=4908427]UCHIHA[/MENTION] I'll have a look at it and integrate it into the next build, but probably it will be next year until I can provide with a new version.
[Nexus 7 Android Development] jorgesedavi:
I had the same problem a week ago with this rom, also there were errors type "You cannot access to that document" when I opened pdfs from a file manager.

Try to wipe cache and Dalvik cache from recovery and reboot, it solved the problem to me.:good:

[Nexus 7 Android Development] AndDiSa:
[MENTION=7894717]robgriff[/MENTION] probably it's sufficient to grant access permissions for storage for the browser.
[Nexus 7 Android Development] robgriff:
They were already set, I checked, even though chrome asked for permission so was acting correctly. It was saying it failed download because of missing SD card. Downloads from Tapatalk were OK. I tried chrome Canary, and Firefox which said it failed due to unknown size. This was on a fresh install on 2 occasions. I tried disabling download manager to see if chrome would do anything different and as it didn't, I went back to re enable DM and thought for good measure I would disable and enable downloads too and it started working with chrome. I had to reload the ROM and the same problem happened and the same solution fixed it!!
[Nexus 7 Android Development] guilou123:
Same for me. Fresh install too.
[Nexus 7 Android Development] adstraylight:
I think I had the same problem, but my solution was to force stop chrome and relaunch after granting the storage access iirc...so it sounds like a child process of chrome's needs to be reset after giving it the correct permissions.
[Nexus 7 Android Development] ufa:
Cannot encrypt my device. Is it possible to include such a feature?
[Nexus 7 Android Development] ignitionnight:
Are you sure you want to do that on this device? This ROM makes the best of an over the hill and flawed device. I can't imagine encryption wouldn't make it that much slower. Encryption is nice but at the expense of making the device unusable I personally wouldn't think it's worth it.
[Nexus 7 Android Development] ufa:
Encryption is the only way to go, if you are willing to use it out of your house. It should already be default to android.

Anyway my ancient tablet handles encryption just fine, maybe because it happens on the hardware level, so it wouldn't impact performance that much.
[Nexus 7 Android Development] danibus:
Yes. If you dont want gapps, but you can do it, extract apks (remember they are fron play store for Nexus, with correct apk) and then format rom without gapps.

If you download from other stores, maybe you download the apk for arm64 instead arm only.

Congrats for your great work! Help needed ;)

Hello!

Here is a nice tutorial from iFixit for your battery !

I own a Nexus 7 (2012 ,1st gen) and being confined made me unbury my sleeping beauty. I wish I could install CM14.1 on it but I have a desperate case to submit to the expert community:

When my Nexus 7 was under the original OS (Android 4) everything was functional and smooth, then I upgraded to 5.1.1. and everything became laggy and the worst is that when I plug it into any PC (different Windows versions, Mac OS Sierra, different Linux versions) it is not recognized any more ;-( The USB port of my Nexus is working because it is charging and it's also working with an OTG cable; I even replaced the port by a new one to make sure it was not faulty...) So here I am with a great tablet but the worst OS!!! An dI just can't do anything without that USB connexion. Do you have a clue to help me? Of course, I activated the Developer options and USB debugging; of course the tablet is not rooted ;-(

I tried, in vain, plenty of rooting apks.. (Towelroot, Kingroot...)

Thanks for your help!

The recovery mode page indicates this:

I opened the hood 2 days ago and I found that connector was almost detached from MB.

I linked it properly and now the tablet is not switching off by himself anymore.

Charging is taking lots of time still, so my understanding is that battery is EOL

[Nexus 7 Android Development] Schwamml:
Hi [MENTION=8255917]nexusnagasi2017[/MENTION], i faced the same issues with the Nexus 7 but i managed somehow to solve both, battery and USB issue. First thing to say, never give up :D It's a few years ago that my Nexus wasn't recognized anymore on the PC (not on Windows not on Linux). So i can't remember exactly what i did to solve.

But can you access the bootloader oder recovery?

Did you try to connect the Nexus on the PC an going into bootloader while attached on the PC? You should hear the sound of a new device even if you can't see it after.

Or look at some post for different fastboot versions.

Hope you will recover the good old Nexus. With this Rom it's still a very good table an attached directly on current it never runs out of battery :D

Thank you [MENTION=2188693]AndDiSa[/MENTION] for fantastic ROM. Installed some days ago and works well. Anyway, I would like to have the option to overclock cpu a little, no problem with less battery life.

Maybe there is some app I can use (with root) or would need another kernel? Not sure if this rom is already overclocking cpu

thanks
[Nexus 7 Android Development] AndDiSa:
[MENTION=4831487]danibus[/MENTION] the ROM currently is using up to 1300MHz for 1-4 kernels even if 1300MHz is specified to be used only for one active kernel. Using e.g. KernelAdiutor you can try to increase max. frequency. If I remember right settings for 1400MHz and 1500MHz should be built in but be aware that this might lead to instability and really speaking I doubt you will notice much difference in real life.

The latest ROM 5th May 2020 (dirty flash, no wipe dalvik and cache) seems to using more RAM when idling. I'm vaguely recall the previous ROM using around 430mb and this one around 500mb. Unless I have a false memory.
[Nexus 7 Android Development] AndDiSa:
[MENTION=7044820]breaktheblock[/MENTION] as on *nix like systems there is the most imortant rule: "unused memory" is "wasted memory" it depends very much when you are looking at such a system and what you are declaring as "used memory". Memory is continously swaped and re-assigned for different purposes so withour having a detailed list of the current memory allocation table it's almost impossible to say whether a "ROM" is using more or less memory than different one.

Latest ROMs do not load battery while Nexus 7 rests on the original docking station. Can anyone else confirm this issue?
[Nexus 7 Android Development] mikeataol:
For several versions of this rom, I've noticed that I occasionally had to remove and reinstall the USB cable for the tab to start charging. (If I had taken it off the charger while it was running).

Overall I ignored it, it's a minor annoyance and otherwise the ROM is fantastic.
[Nexus 7 Android Development] andynroid:
Try using another cable to be sure
[Nexus 7 Android Development] street_dog:
I have noticed that too, and sometimes i have to restart, without the cable to get it to charge again.
[Nexus 7 Android Development] AndDiSa:
It's a known issue that the Nexus 7 does not charge / has difficulties to charge if it's booted with the usb cable connected. You need to "trigger", i.e. the device needs to detect a change before charging is enabled.
[Nexus 7 Android Development] street_dog:
now that was something i had missed, because it appeared after i flashed this ROM. but i am aware of it and it doesn't bother me. is this connected to the not chargeable drained battery? that one is a bit annoying.

I might be a really lucky guy, because, as my battery was around 44%, I've plugged the cable in and I've just done two tests : first, a reboot and second, a cold start. In both cases, it's still charging as expected, so I dont have this issue at all on my grouper...
[Nexus 7 Android Development] :
Ime, it's intermittent. I can go weeks without it happening then, seemingly out of the blue, it'll happen again. I've no idea why it happens (that is, the exact circumstances) but it does. I'm in the habit of checking that it's actually charging when I plug the cable in.
