No problem accessing a Kingston 32 GB USB 3 stick in FAT32 on m'y Nexus 7 here. Can you access your stick on a computer? Which file system is it? Have you tested it with another USB OTG câble?
[Nexus 7 Android Development] berthur:
Under Windows and Slimkat there is no problem acccessing it.

The file system is NTFS. Maybe that is the problem...
[Nexus 7 Android Development] fsw_informatrix:
I think it is, you should really try with another FAT32 stick, to see how that goes...
[Nexus 7 Android Development] psiphi:
Exactly. NTFS is not supported.
[Nexus 7 Android Development] berthur:
I tried NTFS/exFAT/FAT32 formatted drives.

It looks exFAT and NTFS are not supported.

Fat32 is the way to go.

Thanks everyone in helping me sorting this out! :good:

guys would like to know...in order for me to install twrm recovery ...izzit a must to have bootloader unlocked ? ... can i install twrm with locked bootloader ? ... is that possible ?
[Nexus 7 Android Development] Portgas D. Ace:
Unlocked bootloader is mandatory.
[Nexus 7 Android Development] mikefive:
short answer: no :)
[Nexus 7 Android Development] gps3dx:
AFAIK, the solution is pretty simple and the fault is google's server, not the rom nor gapps ver or edition ( hell this issue even exist for play store working on MicroG's framework ).

perform the steps on this XDA article as it apply to ANY custom rom on ANY device....

( i.e perform the steps under 'How to Possibly Unblock Google Apps on an Android Device' ).

Hello,

I've got a bug with headset sound after few minutes on function no sound on left or right lost stereo...:confused:
[Nexus 7 Android Development] AndDiSa:
[MENTION=6140286]laugeek57[/MENTION] do you have a logcat which you can provide me?
[Nexus 7 Android Development] laugeek57:
How can I make logcat :confused:
[Nexus 7 Android Development] AndDiSa:
[MENTION=6140286]laugeek57[/MENTION]

If you are on Linux you can connect your device via USB with the PC and type on a shell

adb logcat | tee log.txt

the file which will be created (log.txt) contains some information / warnings / error messages which can give a hint what might went wrong.

Firstly kudos to the developer to make my tab alive & latest even after 4 yrs.

One bug found: I cannot download anything on my tablet through browser, It says SD Storage not found...

Any solution??
[Nexus 7 Android Development] pincher65:
this not ROM bug.

check permissions at the browser. reinstall the browser, make a pure flash ROM and Gapps

[Nexus 7 Android Development] Paddy's:
Hi,before i install this amazing rom i'd like if some of you could answer these two questions:

1) Is this rom smooth and fast with chrome browser? (i know there are other browsers but i prefer using chrome as main browser as i am doing now with slimkat and parrotmod)

2)Do you have problem using and updating the standard facebook and messenger apps or do they slow down the tablet? (i know there are lite versions of these apps but i'd like to use the standard versions,if possible) Thank you
[Nexus 7 Android Development] bangsergio:
Go ahead everything is working fine, clean install and install apps one by one from play store, no errors only small fc but no big deal.

[MENTION=6140286]laugeek57[/MENTION] Do you have an app installed which is changing / applying sound effects?

Thank you very much AndDiSa !

hi

i instaled rom like like instructions of post one exactly (All steps). but my apps during runing are close:(

and tow other issue:

1-power menu is very Raw. it just has "power off" and "restart". it seems it need to screen shot, airplan mod, submenu of restart(such as recovery mod and ...)

2-how to going to recovery mod when tablet is off and we turn it on?

thanks in advance for your Guidance
[Nexus 7 Android Development] Danielmariuss:
Hello,

I have not yet installed this ROM, but I want to ask, is stable, 3G works?

Thank you
[Nexus 7 Android Development] AndDiSa:
I guess you were using CM or some other custom ROM where you have more options in the menu.

Regarding the FCs did you restore the apps by Titanium? In that case it's very likely that your apps are not working correctly.
[Nexus 7 Android Development] abhifx:
1) this is AOSP where only power off and reboot options are available as intended by google.

2) just press both volume and power button simultaneously in off condition, the device will start in boot loader mode. use volume to select recovery mode and enter using power button. in on condition you can also issue adb restart bootloader for same effect.

very stable, however it seems tilapia users are facing RIL issue on latest build. you might want to wait for next build
[Nexus 7 Android Development] shaggyskunk:
You can use Power Menu or Reboot Manager from the store - Both work well and give you Advanced Reboot options.

Music from USB otg SD card

Thank you DEV for a reviveing rom. I use it in a dash car I just builded. My problem is also the usb stick - I use a powered usb hub and a 60G FAT32 card.

Yes, I can explore it but cannot make music players to play another song. In explorer I see the content, players alone cannot discover the sd card but play the song I click in explorer. After song finishes, IT STOPS. Players - I tried several - will not see the other song/folder. I play flac. After a week of tests with different roms and apps and magisk modules, yesterday somehow all worked....in the end. Hard to say how. Today i did not test the sistem yet, a little latter. Keep your fingers crossed, thank you, will be back.

Last edit - well...does not work. Bare rom - no gapps - only magisk - looses usb connection - shows usb host not working. Only way to go on - I used selinux and usb mount apk. Native music player play 1 mp3 only if selected in explorer, neutron - for flac - also plays only one selected song.

As you know, inner storage is too small, especialy for flac. This one seemed to me the best rom for the old Nexus...(2012). Any solution for playing music from SD?
[Nexus 7 Android Development] Publicorderkeeper:
Something terrible has happened... I have used this ROM(2019/04/05). There were random reboots from time to time. Yesterday after such reboot internal memory has become read only. I can't delete files and can't flash anymore. If I delete some files, they're reappeared after reboot. And now my nexus 7 is rebooting after 5-10 minutes. Please, help. I hope that is not the end for my nexus 7...
[Nexus 7 Android Development] TureX:
Try a fresh clean install, format system, all the cache and data, but i think is a memory issue.
[Nexus 7 Android Development] Publicorderkeeper:
Can't format anything using twrp - all data're reappeared. Can't install anything using PC, because bootloader can't be unlocked...

random reboots

If nothing else helps, try remove/reconnect battery.
[Nexus 7 Android Development] Sam Nakamura:
Yeah, that's the infamous "EMMC brick bug", unfortunately the N7's are known to may have a specific faulty memory chip (mostly from Kingston) built in that could start failing at anytime, actually I had to replace the motherboard of my N7 a year ago with a used one (my was a Kingston EMMC chip and I found a 32GB Hynix board for just 20 bucks) as the memory itself is soldered to the mobo and not replaceable without deeper knowledge of soldering (especially BGA reballing and writing firmware to the plain chip before you possibly start flashing any ROM), you can refer to this thread for more information and possibilities about this:

i still believe that battery unsoldreing/soldering can solve.

Unfortunattely this can not solve otg music playing.
[Nexus 7 Android Development] mikeataol:
Hi the battery isnt soldered. it uses a connector, but I have seen this on other 2012 gen tabs (nook)

I think once it goes to read only, it's cooked.

ROM version for May will be released in the next couple of days.

[MENTION=2188693]AndDiSa[/MENTION] and I identified two bugs in the kernel regarding the lowmemorykiller.

Changes to memory management

always

require a lot of testing to see if there are no unwanted side effects.

I´m testing the new kernel since four days and it looks OK so far (always keeping in mind that - no matter how many tests you run - testing can

never

cover all cases).

edit:

to all Nexus users

if you experience any issues with the new kernel, please feedback - providing logfiles!

Three things that you may watch out:

1. Is the linux kernel OOM killer invoked when you run memory-demanding apps? This should not happen when the LMK is working as expected.

2. Does the LMK kill memory-demanding apps that run in the foreground or even during their statup process?

3. How much of the ZRAM swap space is used?
[Nexus 7 Android Development] AndDiSa:
May 2019 version uploaded

as [MENTION=8559165]OlliWi[/MENTION] already announced the new builds with the May 2019 security patches are uploaded. You can find the download-links in th OP.

The following things are changed with this version:

May 2019 security fixes

some bugfixes in LMK which after some time killed wrong processes

improved charging behaviour

... and as always: flash on your own risk

[Nexus 7 Android Development] Nexus7_tilapia:
Hi

Does it need to do a clean install because of changes in kernel?

[Nexus 7 Android Development] AndDiSa:
No, update install is sufficient.

[Nexus 7 Android Development] Alex_Lyt:
Still not more than 550 mA (
[Nexus 7 Android Development] OlliWi:
Still working on that issue.

The behaviour of the charger IC and/or its driver is quite strange.

It is not reproducible to which value the

input current limit

is set when you plug it into an AC adaptor.

It can be anything from 300 mA (the lowest possible value) up to 1200 mA (highest value with current driver) and sometimes the charger IC is also changing this value during the charging process.

The reasons are unknown. Can be anything from a configuration issue of the charger IC, a buggy charger IC, a driver issue....

Neither the internal logic nor the register configuration nor any hardware bugs of the IC are publicly documented, so we have to use a try and error approach to improve things.

What you can try is to unplug the USB cable (while connected to a AC adaptor) and reconnect it within 1-2 seconds. In some cases, the IC will switch to a higher current limit....
[Nexus 7 Android Development] terranaut:
i've used this rom for years, and its been great on the 2012 grouper i've owned since 2012.

today i have an issue i have spent hours trying to resolve - i simply cannot get into recovery mode anymore.

the typical power/voldown isn't working, and i tried all the other methods like power/volup/voldown, power/volup, and so on. what is the next step when you cannot get to recovery mode?

i have twrp installed, and i usually use magisk to root (though now i cannot access twrp nor can i unroot via magisk since i cannot access recovery mode). thanks for any advice as i have looked for an answer most of the day today but now am surrendering my search.
[Nexus 7 Android Development] mikefive:
maybe developer options and adb works:

> adb reboot recovery
[Nexus 7 Android Development] AndDiSa:
If you are on a running system you can try to connect with ADB and then

ADB reboot recovery

Looks as either the power- or the vol- button has some issues.

Edit: [MENTION=9516818]mikefive[/MENTION] you won the race ... ;)
[Nexus 7 Android Development] paasoares:
Also you can try this method :

ADB reboot bootloader

fastboot boot path_to_TWRP.img
[Nexus 7 Android Development] denzel09:
Sorry for questions. I have a nexus 7 tilapia, i don't use it from at least 6 years. It is with official stock android 5. Someone can explain me which are the steps to flash the recovery and this rom? I have fear to brick it.

Thank you.
[Nexus 7 Android Development] mikefive:
short answer:

boot into bootloader(fastboot):

https://source.android.com/setup/build/running#booting-into-fastboot-mode

unlock bootloader:

https://source.android.com/setup/build/running#unlocking-the-bootloader

important: boot once again in your old stock-rom! if you flash the recovery right after unlocking bootloader *without a reboot* you prevent the orginal recovery from fix the partition table and TWRP would not find a system partition. if you see the welcome screen you can turn it off again and proceed to:

flash suitable TWRP:

https://twrp.me/asus/asusnexus720123g.html

(or look at the first post for an twrp image for your device)

flash custom rom:

read the instructions in the first post.

..ah: since this is an google device, there are only minor chances to brick the device, as you can always flash the factory image if someting went wrong and as long the bootloader is intact.

the factory images can be found here:

[Nexus 7 Android Development] Sam Nakamura:
What??? But this method misses out the fun part!

Tinkering on old devices is actually a real joy, no encryption, dm-verity and a natively unlockable bootloader is just awesome and you keep perfect control by doing it manually... It's a crazy world, one's "headpain" is another one's enjoyment! :silly: lol
[Nexus 7 Android Development] denzel09:
All works good. Installed also fstrim and it's better. But the opening of each app is really a bit slow, too old this tablet. Is there any kernel with bit of cpu/gpu oc for this Nougat 7.1.2 ?
[Nexus 7 Android Development] OlliWi:
OC won´t help with slow opening of apps. The eMMC of the Nexus is eMMC 4.41 standard which doesn´t have any hardware read cache (which was introduced in eMMC 5.0 standard).

Also the 8 and 16 GB versions of this tablets have slower eMMC than the 32GB versions.

Raw Read/write performance of my 32GB tilapia is about 40/20 MB/s.

eMMC with read cache do over 100 MB/s read speed (tested on an old Honor Holly, 16 GB with 64MB read cache).

App starting time also depends on how many free RAM is available. If the lowmemorykiller (LMK) first has to free up a lot of RAM, then it may take a couple of seconds until a new app will start.

There may be a small improvement in an upcoming kernel version which I am testing since a couple of days.

Also there may be some parameter tuning for the LMK possible after two bugs have been fixed with the latest ROM version.

Stay tuned.

Anyone else have the same problem ? Any solution , advice ?
[Nexus 7 Android Development] Sam Nakamura:
I'm full-time working myself (not Android related), have kids and hobbies besides Android... just like the big majority of our lovely xda-developers community, so don't get the impression that all here do code 24/7, nothing could be further from the truth BUT lots of us are Android enthusiasts interested into the inner workings of the platform we daily use, doing stuff manually is just a great way to learn about Android, it's also a great way to teach yourself technical background and over time gives you the expertise to help yourself (or others) if something doesn't work as intended, to be less depend on someone answering your questions on the forums or even help the developers debugging, in the end you shouldn't forget that android actually is a open source project and aims for everyone to contribute, some contribute just a little bit and other more or even a lot, if there's enough interest - there's a way, it's rarely about the individual circumstances alone, at least to my experience...

Found this thread last week. Helped a friend with a very slow Nexus 7 2012 WiFi get it all set up and now running this rom after trying a few other builds that didn't seem to do justice to this device. Very impressed with the results after installing this build. Took it to the next level doing a bit of my own debloating too. It handled it without any force closes or problems. YouTube Vanced runs great. Got rid of super su and the ROM handles Magisk without any problems. Thanks OP for the build.

This is a pity to hear! It is great that we - in my case actually my sister - can continue using this almost "ancient" but overall reliable tablet until nowadays.

Hello Guys, would share an issue with mine ... Even in sleep mode, battery discharge lineary in 24 hours (while I never touched it).

Any idea of what could drain battery like that ? In settings menu, it seems Android Platform is keeping it somewhat active ... Don't know from what It could come ^^
[Nexus 7 Android Development] AndDiSa:
[MENTION=9700272]Warfare777[/MENTION] this sometimes hapens when there is e.g. an update of Google Play Services and synchronization hangs for one or several applications. Go to settings / accounts / synchronization and check whether there are one / several synchronizations hanging. If there are, try to re-sync by switching on/off the automatic synchronization. If it does not help, try to reboot. Most of the time this issue vanishes after a short time.
