[MENTION=3865771]fidoedidoe[/MENTION] I never said that a flashable zip will be possible ... I suppose there are too many differences in the device tree which need to be aligned. It was more an idea to keep in mind.
[Nexus 7 Android Development] slybunda:
i got this rom installed now. how do i get to access the nexus via usb connection? mtp mode and mass storage dont seem to work. the photo ptp mode works.
[Nexus 7 Android Development] AndDiSa:
[MENTION=2556761]slybunda[/MENTION] ptp and mtp are working fine, mass storage is no longer supported by Android since Lollipop (?)
[Nexus 7 Android Development] CutGlass:
The most frequent error message I get is that MTP host has crashed, not that I'm complaining, I regularly transfer files onto my son's nexus and this ROM is excellent as it's made the device usable again (grouper). I also feel more re-assured that the security is up to date since he needs a basic device for school (not something I agree with) and I'd rather he used an older item than a more expensive one, if it weren't for this ROM, the nexus would be landfill, so thank you.
[Nexus 7 Android Development] iamelton:
my use case is exactly like yours, and i agree 100% to what you said.. :laugh:
[Nexus 7 Android Development] AndDiSa:
Mtp service stopped should not have any influence on file transfer as it is restarted immediately.

(BTW. I can see this behaviour on several of my devices, not only on the Nexus 7, but I don't know what's the root cause of it)
[Nexus 7 Android Development] CutGlass:
Like I wrote, not complaining just pointing out that something is not quite right.
[Nexus 7 Android Development] slybunda:
will try it again when i get home. rom is running amazingly fast and smooth so far i dunno if its the rom itself or just because of the factory reset. time will tell.

i got a issue with the lock screen. the swype to unlock requires too fast a swype to unlock., my baby struggles to unlock it. so iv turned off the lock screen itself. things are running good so far.
[Nexus 7 Android Development] CutGlass:
I find this sometimes too but i've learned to use my fingers rather than swipe my child across the screen ;)
[Nexus 7 Android Development] slybunda:
i see the rom as google search running all the time. is it possible to disable it and remove the search bar or will it cause issues?
[Nexus 7 Android Development] Charles IV:
I get this issue with lineage 14 as well.
[Nexus 7 Android Development] adstraylight:
I had this once, it turned out to be a Windows driver issue, ie the pc was trying to load the wrong one. I fixed it by:

finding the faulty entry in device manager,

opening its properties,

clicking update driver,

clicking browse my computer,

clicking let me pick

Choosing the uption that includes the term 'usb' (I think it was called mtp USB device).

Hope this helps...

Well, I did this. Did not get any pictures. It works as well as the Qi charger in my Nexus 7 2013. The POGO pin closest to the bottom is positive and the POGO pin closest to the top is negative. Soldered small wires to the pins internally. Need a low wattage small soldering iron. I then found the positive and negative on the Qi receiver and soldered to those. Centered the Qi receiver, taped it down, and put it together. This would not be a project for someone that has never soldered before. I have lots of experience. There were some minor caveats, but nothing I could not handle. Could chat with anyone wishing to try it. I used the following Qi receiver and had no particular reason.

TYLT VU Mate Qi Wireless Charger Receiver for Samsung Galaxy Note 4
[Nexus 7 Android Development] Charles IV:
cool, how fast is the charging?
[Nexus 7 Android Development] ffejy462:
I did the same thing with my galaxy nexus and an Amazon Kindle Fire HD. I had to use two coils on the Kindle because it was really finicky about input voltage if I remember correctly. It's a relatively easy mod most people could tackle after a few practice soldering runs. It's a shame that wireless charging is becoming increasingly rare. Google, if I'm not mistaken, has abandoned it completely.
[Nexus 7 Android Development] n3kf:
It is not any faster then USB. Looks like about 20% an hour. I am only using a 1 amp charger hooked up to the Qi charger. Keeps the heat down. It may be possible to go faster with a 2 amp charger, but I just let it charge over night.
[Nexus 7 Android Development] slybunda:
turns out the pc is asking for a missing driver for the nexus 7 in device manager. anyone got a link for the driver?

well it turns out that its in usb debugging mode. thats sorted now
[Nexus 7 Android Development] ashukla:
Just an update, I reverted to the stock ROM for a while since I couldn't get the camera to work. Not that it mattered, but it just bothered me :silly:

Tried the June 5 version since stock got too slow with all the apps loaded, and behold CAMERA WORKS just fine. All the camera apps mentioned in reply to my previous post work. Have been using CameraMX since.

A Big shoutout to [MENTION=2188693]AndDiSa[/MENTION] for this great ROM. My tab is now usable for the little ones :good::good:
[Nexus 7 Android Development] black_bottom:
After exactly installing Rom, gaps and supers as written in 1st post without any problems.. It seems I don't have googleplay. What do I do wrong?

Gesendet von meinem LG-H850 mit Tapatalk
[Nexus 7 Android Development] AndDiSa:
Generally there shouldn't be any issues, but I've two questions which might indicate the direction to search:

What Gapps package did you install, the package linked in the OP?

If you installed SuperSU, what version of it and did you install it in systemless mode?
[Nexus 7 Android Development] black_bottom:
I installed BeansGapps-Mini-7.1.x-20170509.zip

I installed SuperSU-v2.82. In this context what*s the meaning of "systemless"?

In the end (after wiping system, data, cache, dalvik) and installing the actual ROM, gapps an supersu from 1st post: there is no googleplay in the app-drawer und I cannot connect to my google-account. Please help. Thanx a lot.
[Nexus 7 Android Development] AndDiSa:
[MENTION=1681823]black_bottom[/MENTION] /system parttion is very small to keep the rom / gapps and probably rom other modifications. Please read post #2 how to install SuperSU in systemless mode. This prevents SuperSU out of /system und prevents issues due to overwriting / deleting components from it. As everybody else has the GoogelPlay app installed I suppose it's a space related issue in your case.
[Nexus 7 Android Development] Charles IV:
[MENTION=2188693]AndDiSa[/MENTION] i had a similar issue -

i used opengapps (because it was already downloaded on my tablet), flashed it in zip queue, and i didn't have it, then i flashed it again, and i had google play store. I assumed it's because i used opengapps, but i got no setup wizard or anything.

dw about my issue, just to let you know about it. I was just testing to see if my uv worked (it didn't), and I'll probably go back to los, as i think i just prefer their modifications over stock android
[Nexus 7 Android Development] slybunda:
tablet slowed down to a crawl today. was unusable. needed a reboot to fix
[Nexus 7 Android Development] black_bottom:
I use TWRP 3.1.1 fron 1st post.

I wiped system, data, dalvik, cache, internal space. So I think my grouper is completely empty. Correct?

after this I check out /system from the terminal within TWRP.

\system is empty (no files), only with the also empty subdir \system\lost+found

I tried again installing ROM + BeansGapps from 1st post, after this I prepared systemless mode from 2nd post, after this I install SR_supersu from 2nd post. Same result, no googleplay.

Then I tried the same but used nano_opengapps which are a little smaller then beansgapps and supersu systemless. Also no googleplay.

I really don't know what to do, what to change. what do i do wrong. Need help, thanx.
[Nexus 7 Android Development] AndDiSa:
[MENTION=1681823]black_bottom[/MENTION] I don't know what to say and how I can help you. It's exactly what I am doing when I am flashing the ROM and I do not have any issues with google play. Can you probably post / send me a logcat? Probably one can identify the root cause of the issue ...
[Nexus 7 Android Development] pehlm:
Try OpenGapps pico (I'm using it), when using this, free space in system after flashing ROM, Gapps and superSU (systemless) is about 139 MB. You must of course wipe the device again before flashing pico. I can even flash ViperArise, but then it is only 32 MB left in system-partition. But it works! Hopes it helps.
[Nexus 7 Android Development] black_bottom:
Using opengapps pico I got it ! Is there any chance to extend the space for /system? why for some user its enoungh and for other like me not although I erased /system in advance. weired.

But: configuring langue to "German" the screen welcomes me on my Nexus 7 and ask howt to configure.. I choose "configure as a new device" and after this I get a forced close. When I open the app again the same result, no chance. What I have to do?
[Nexus 7 Android Development] len207:
What worked for me was to install the ROM only, boot the device and do minimal setup then go back and install Gapps and Supersu. After restart you should have a working system and you can make whatever additional setup you need from there. Good luck...
[Nexus 7 Android Development] pehlm:
Glad that it worked. You should not change the system partition size though! It could do the device unusable. The only thing that can extend system is to remove systemapps but this ROM is already very pure AOSP so it is difficult.

The setup wizard may crash, it is a common bug. Just configure the wifi in Android settings and then click the google play app and login. It should work. The right way, though, is to flash like @len207 proposes. Good luck! :)

---------- Post added at 16:45 ---------- Previous post was at 16:43 ----------

This is the right way to do it. :)
[Nexus 7 Android Development] black_bottom:
:o) Jackpot :o) Use opengapps pico and systemless SU and follow the way len207 posted. Thanx a lot!
[Nexus 7 Android Development] Silenthunter84:
My battery is like this since yesterday.

Is it a ROM problem?

That spaces in the screenshot I really turn off the tablet to try to solve.
[Nexus 7 Android Development] n3kf:
Have you installed any new apps? You might want to temporarily install an app that will tell you if an app is keeping the device awake (wakelocks).
[Nexus 7 Android Development] Charles IV:
To add to this, you can boot into safe mode to see if it any of the apps - but it doesn't tell you what app is the problem.
[Nexus 7 Android Development] rafapoza:
Jack is not working

Hi,

first of all, thank you very much for your commitment, work and support. I've realized my 3.5mm audio jack is not working fine with the current build (I don't know if the previous ones had this issue because I had not tested before). Am I the only one with this issue? (I have the 8GB grouper version)

Regards,
[Nexus 7 Android Development] 4ktvs:
I did the install per the OP while it's better than 5.1.1 it seems a number of apps can force a restart.
[Nexus 7 Android Development] AndDiSa:
Did you check for the permissions? In my experience if there is a closing app in almost all cases there was some permission missing. You should be able to see that also in the log.
[Nexus 7 Android Development] Silenthunter84:
Is it possible that is the battery that are dying?
[Nexus 7 Android Development] Agent_Sm1th:
I'd just like to say thanks for this rom. My Nexus 7 (tilapia) has a new lease of life after sitting in the drawer for the last two years. Had no issues installing this, and it works flawlessly. Cheers
[Nexus 7 Android Development] [D4v3|R4v3]:
I just successfully flashed the latest version (coming from 6.0.1). Unfortunately though I don't manage to get Netflix running. The store says it's not compatible with my device. Does anyone know, what the problem could be?

N7 repair/replace

Greetings.

First, my sincere thanks to AndDiSa and aaopt for their hard work and ROMs

which have breathed life into my old N7.

My 32GB grouper took a dive off the nightstand yesterday resulting in a

cracked screen and useless digitizer so I'm faced with the fix, replace or

upgrade question.

The repair info I found after a brief search seems dated, so I thought

I'd pose my questions among active N7 users with more current experiences.

Apologies in advance if there is a more appropriate thread.

Your thoughts and recommendations are appreciated.

1. Replace / Upgrade?

I prefer Nexus devices for access to tools and ROMs. I've only owned the

2012 model, but am open to the 2013. I don't game, but do consume the odd

video. Don't need 3G

Groupers seem to be running ~ $55 USD on ebay at the moment

Nakasi running ~ $80

If you folks know of better (in price or reliability) sources for used nexii, that would

obviously be helpful

2. Repair?

While there seem to be some B or C grade used OEM screen+digitizers (~30), there

are some ebay vendors selling aftermarket assemblies including the bezel for

~25. Not sure who the manufacturer is in that case (possibly Chungwa).

I have not repaired a N7 before and the assemblies-with-bezels seem to

be a bit simpler.

Thanks again.
[Nexus 7 Android Development] Agent_Sm1th:
I have just replaced my cracked screen. Took about 45mins as I had to heat it up with a hairdryer to loosen the glue. Its been worth the £20 for the replacement, coupled with the fact that I then discovered this fantastic ROM which makes it feel like new again. I used YouTube as a walkthrough to repair it.
[Nexus 7 Android Development] goldx:
My inclination is to repair it as well. The 2012 N7,combined with these nifty ROMs really does all that I need. I did run across videos along the lines you mentioned, complete with hair dryer softening of the adhesive. Most of the screen/digitizers I've run across have been for after market units (Chunwa or some variation thereof) versus the OEM Hydis panels. Some of these appear to also include the plastic bezel. The few used OEM panels I've come across are listed as B or C quality.

Has anyone here used/had any experience with those aftermarket assemblies? Are there visual/quality/performance issues with them, etc?

Thanks again.
[Nexus 7 Android Development] ignitionnight:
Netflix is using safetynet to block downloads from the play store. Search for it on apkmirror and it should work fine after you install it that way.

I have been getting major slowdowns on this build that I never had on the older builds. Same problem [MENTION=2556761]slybunda[/MENTION] mentioned a few posts up. Only a reboot fixes it. Can't even reboot half the time though since its so locked up, have to hold down power to hard reset. Anything I can do to fix or prevent this from happening?
[Nexus 7 Android Development] slybunda:
along with the heavy freezing it looses the background wallpaper i have set and goes to a black background,
[Nexus 7 Android Development] AndDiSa:
[MENTION=2556761]slybunda[/MENTION] I don't know for what and how you are using your tablet because I cannot reproduce your findings and the background issue is indicating to me that some configurations / permissions are not set correctly.
[Nexus 7 Android Development] n3kf:
I get this every now and then. It seems that memory gets very low right before this happens and the tablet just goes out to lunch. Typical of what it would do a lot of without the parrot mod stuff. I don't quite understand why if the low memory is set the way it is, why I get very low memory. Seems like something grabs a big chunk and the tablet goes out to lunch. Sometimes, if I let it sit for a while, it will come back to life. At that point the UI usually has crashed. I use Nova and when that happens, it always loses the wallpaper. It's just a black background and I need to set it again.

I am experimenting with some settings, but this does not happen to me a lot. I have also learned not to open too many apps at once. It seems a major instigator of this for me is Chrome. I just figured this was a downside to the horribly slow flash this thing has in it.
[Nexus 7 Android Development] adstraylight:
I get the same thing on the unlegacy k3.4 rom, every so often, it's like there's a runaway memory leak. Symptoms as you say, systemui crash, nova loosing wallpaper, tablet lockup. For me it quite often happens if I invoke Google Maps.

Edit: Thinking about it a similar thing used to happen occasionally on MM, and I had a hunch this was actually a memory leak in systemui.apk, my work around then was to kill the systemui with a root task killer whenver the screen was off.... I don't think this will work now what with the tighter security in N.....time to play methinks..
[Nexus 7 Android Development] AndDiSa:
[MENTION=6824216]n3kf[/MENTION] It's a known issue that our hardware is not very well prepared for serving many different apps in parallel so it's better to try to keep the set of applications running in parallel as low as possible. Especially applications with a high memory footprint may cause pain. Regarding Nova-Launcher and the wallpaper I do not use it on my tablet because I installed the Pixel-Launcher and I do not have those issues.
[Nexus 7 Android Development] adstraylight:
Ok, here's a thing, did some rooting around to do with system ui crashing, and came up with this:

https://play.google.com/store/apps/details?id=com.sneakyapps.restartsystemui1&hl=en_GB

Figured what the hell, it'll either do something or it won't, so gave it a try. On first run it put up a notification saying that the bug had been fixed, and told me to reenable the Google app, but it didn't need reenabling, so I then tried to restart systemui using it's two buttons, and only method 2 seemed to do anything (needs root btw).

I then tried maps which locked up, and required a forced restart (long press of the power button), this took a very long time to perform, to the point where I thought the system was in trouble, and was on the verge of forcing a reboot to recovery, but it did eventually start.

Thought the app was a dead end so uninstalled....BUT since then my system has been running really well, including maps and multitasking.

Would be interested in other's experience.

In the description for the app, it mentions support for the recent influx of system ui crashes on older hardware btw....

Edit: further googling has found that this may be related to a bug mainly affecting Samsung devices, where systemui would FC repeatedly, the fix seems to have been to uninstall updates to the google app, I'm guessing the app I found may be a little more nuanced than that? Don't know, but it may deserve further investigation by someone with more in depth Android knowledge.
[Nexus 7 Android Development] [D4v3|R4v3]:
Thanks! That is what I did in the end. Couldn't remember anymore doing the same thing with the old 6.0 ROM.

Everything runs smooth now. Only things remaining are the charging problem, where it doesn't recharge anymore unless I turn the tablet off. Another thing that's not quite working is the file transfer. After copying some files (everything between 100MB and 2GB) it sometimes loses the connection and aborts the file transfer. Does anyone have similar issues (specially concerning the latter)?
[Nexus 7 Android Development] AndDiSa:
[MENTION=4096882][D4v3|R4v3][/MENTION] Your problems with file transfer in combination with your charging issues in my opinion is a strong indication of some problems with your USB connection. Either the port or the cable you are using ...
[Nexus 7 Android Development] [D4v3|R4v3]:
I would've guessed the same. Only thing though is that I didn't have that problem with your old MM ROM. The charging and file transfer issues started, when I updated to 7.1.2.

Anyway in the end I somehow managed to copy all my files without an interruption. After two or three restarts it worked ...seems to be a hit and miss.

Nevertheless I'm really grateful for this ROM! You did an excellent job in reviving my N7! :good: :good:
[Nexus 7 Android Development] slybunda:
when it works it works good. would be good if the issues get sorted.
[Nexus 7 Android Development] capounet:
Strangely, I installed and then uninstalled this app and after one day of use, I did not face anymore forced restart.
[Nexus 7 Android Development] petrus764:
Great rom, works really well for my bedtime netflix needs.

Had charging issues on mine aswell a couple of years ago, its a well known hw defect for this device. Solution is to buy a new usb + jack assembly on ebay for a few bucks.

Brought mine back to life with a new charging port, takes 5min to replace the old one.
[Nexus 7 Android Development] pehlm:
@AndDiSa can I ask you if you are sideloading the official Pixel Launcher because it can't be installed through Play Store, it's incompatible with the device. The Nova Launcher is good though on my device but I only wonder, do you think Pixel is more light for the device?
[Nexus 7 Android Development] adstraylight:
Well mine came back, but only after a couple of days, it has given me a lead for further investigation though, I think the problem is connected with the Google app. I'll continue to experiment...
[Nexus 7 Android Development] n3kf:
I have the Google App disabled and still get it. I am suspecting a lot of Google products may cause this. I tend to get it with Chrome. Also Facebook when I link out to something in the internal browser.
[Nexus 7 Android Development] tpuserhp:
I don't use apps with high memory usage nowadays on this device. But I still use chrome.

I wonder if increasing the low memory killer sizes like below would help or make it worse:

echo "18432,23040,26624,32256,36864,46080" > /sys/module/lowmemorykiller/parameters/minfree
[Nexus 7 Android Development] psiphi:
I've been using Facebook Lite and Firefox. Good enough for most stuff.
[Nexus 7 Android Development] adstraylight:
It can happen just after boot, so I don't think RAM is the cause.
[Nexus 7 Android Development] 2ndHouse:
I get crashes quite often too, seems it crashes a little more often with the latest June update. I'm using Samsung 2012 grouper.

The crashes are almost always in Chrome or the Play store for me. Sometimes I can go days without one, then get multiple ones on same day. They sometimes cause bootloops at the launcher screen a few times before it boots correctly.

The crashes always cause a 5 to 10 second red, white or blue screen with lots of thin vertical bars.

I also have to swipe to unlock my device 3 or 4 times sometimes, I have had this problem with both Pixel launcher on NaosProm and Google now launcher with this ROM. I mention this because I wonder if the two problems might be related.
[Nexus 7 Android Development] AndDiSa:
[MENTION=7952223]2ndHouse[/MENTION] Excuse me, but what is "Samsung 2012 grouper"?
[Nexus 7 Android Development] adstraylight:
Hehe, should have been LG....
[Nexus 7 Android Development] 2ndHouse:
Hm, my mistake I thought the Nexus 7 2012 grouper was manufactured by Samsung for some reason, when it seems it was actually Asus. Anyway, just meant I was using the grouper model.
[Nexus 7 Android Development] joeboy00701:
I get crashes quit often. Even a few seconds after start. This is now very frustrating, because the device is completely unusable.

This app 'restart system UI' didn't seem to help. I don't know if crash is the right word for this. May be it's an other issue. I rather call them freezes.

I get freezes​ of the whole system. It doesn't matter, what app and how many of them are running. Only a force reboot helps. The time after reboot till the freeze can be very short, often less than a minute. When the display is off it won't turn on again.

At the beginning i thought it was the lack of trimming. But trimming the /data partition didn't help. I don't know what it is. So i have to ask you guys for a solution.

Btw it is a fresh install of the latest June version after my last post I was mentioning it a few weeks ago. Then the freezes came back again. I don't have the Google app installed, only the pico gapps and the official SuperSU in seamless mode.
