[Q] Just wondering how many of us have a dead N7??? - Nexus 7 Q&A, Help & Troubleshooting

Just wondering if this is something of a user fault from bad/incorrect flashing? or hardware/software from ASUS/Google problems.
If you have a dead N7 from whatever reason other than dropping it or dunking it in water. Please respond, perhaps if there is a significant number of people with problems not caused by physical or water damage. We can with the help of some legal advisors bring this to the attention of ASUS/Google and they might change their minds and do something about all of us???

My died after 5.0.1 OTA update. It booted without problem and worked pretty bad and I rebooted it few times and after some time it didn't booted any more. Recovery worked but I could not unlock bootloader. Luckily I had warranty for one more month and they switched motherboard free of charge. And few hours ago I updated to 5.1.1 (ota) and it works great now (I have three users and there is just small lag when switching between them). Hope it will stay like that.

Mine just keeps rebooting after the Google title and then it gets these lines running on a blank screen then shuts off.

You could fix that, you know, right?

No I didn't know that.
Do I use NRT and just revert back to 4.4 or something?

I'd try that first, unless you have a known good backup stored on device (you should, if not now is a good time to start the habit.)

Cool I'll mess around with it. Thanks!

Np. If its still broken after post more info and it can be figured out.

My sister's N7 is a refurbished model and it has constantly been giving her problems, it would always after a month or so of usage would reboot and bootloop. I would have to boot into recovery and wipe cache or factory reset or even flash the stock image again to get it working. I just got back from being away and its now completely dead, won't even charge. It was running stock 5.1

Sounds like failed memory, or memory controller, by the symptoms of reboots after a month that were fixed by a wipe and reinstall. Once it got to a certain level of storage usage it failed, you wiped, and the cycle repeated. Unfortunately it is probably dead. The good news is you can pick up a replacement motherboard for a very reasonable price on eBay.

Update!
So for my issue, it was the battery.
First, I tried to flash the stock image. Still restarted and got the lines. It drove me nuts!
Something inside me said to order a new battery from amazon for $20.00.
I did that, installed the new battery, flashed, and my nexus 7 is back in action. For those that are going through the fuzzy lines and restarting issue, you guys might want to try that. Worked out for me. Cheers!
Edit: I'm not sure if I would like to go back to updating all the way to 5.1 yet. But 4.1 works for me. [emoji28]

im on my 3rd
today at $165 per piece its a joke its the best tablet you can get under $200. I like to keep a tablet with me at all times because of the nature of my work. and this fits in my pocket assuming a don't have a case. I find the note for a little too small to work on. it's a great device for the money and I'll keep buying them as long as I keep breaking them or they keep dying for something else this size comes on the market at this price. my only real gripe is that the graphics abilities if these devices are a little weak.

I wish I did the same, I let my N7 update to 5.1.1 and its so slow, even removed many apps like "Facebook" and tweaked everything. I dont think the 1st generation N7 is up to par with 5.1.1. Might have to unlocked and downgrade to 4.4.4....

I am so done with Android

I have been using Android since cupcake and it's going to end with my Nexus One. Reasons:
These are problems I've had with various roms, most stock roms, some MIUI:
- The Camera, no matter which ROMS I get when I try and take a picture it reboots the phone after freezing. I cannot use my 5MP camera at all because of this.
- After leaving the phone charging for awhile then going back to it when I push one spot on the screen it thinks I've pushed a completely different spot. I require a full reboot to fix this.
- My keyboard, stock keyboard, sometimes turns all white. You then cannot see what you're typing and there's just this big white bar.
- To fix the above I got Better Keyboard. It force closes often, and sometimes when I try to type with it what I'm typing doesn't get inserted into the selected input box.
- I got five hours of STANDBY (not using phone at all) battery life on Gingerbread. I had to downgrade back to froyo to get normal battery life back.
- After ten seconds or so if you don't use your screen it's supposed to DIM. Regardless of whether or not I'm using my phone it still dims after ten seconds.
So as far as Android goes come October when my three year Bell contract expires I'll be selecting an iPhone. I am done with Android problems of all kinds. That's not to say there's not a lot of things I like about Android but I can't just keep on going with it whilst experiencing these annoying problems, when I've never experienced any problems of any sort on my jailbroken iPad.
Did you ever try using your warranty? Really sounds like you had a dodgy handset.
Sounds like your phone is a lemon. I experience none of that....don't think anything you mentioned is a problem of android itself, you just got unlucky with your phone

Again, this sounds like either something wrong with your rom or a hardware issue. I have never seen this issue.
Yeah, you're an idiot. Sorry, but you're blaming problems that either you have created or hardware problems on Android, the operating system.
But go ahead and leave Android. It sounds like you're not really technology capable of much more than an iPhone (and really, this is probably going to be pushing your technological limits it seems), so that is probably what you should stick to.
I won't be as harsh as the others
The only problem you mentioned that is N1 related is the screen, rest are probably rom related. If your flahsing all those roms you already know they are not guaranteed to work on all phones.
If you want to try another phone, try the new Sensation or equivalent. Android is still much better than Apple. IMHO. That said, my son and his wife have been Apple users for 20 years or as long as I can remember. They have used nothing else. So, I think the iphone is a good phone, just not for everyone. As android is not for everyone. I once thought Blackberry was unbeatable, I was wrong bigtime. When I first started using them, they may have been. But, not any more.
You are probably like me and get an itch to try something different. I am currently running RCADSmix Sense rom with a number of issues. But, I like it so much, I will put up with the issues. Probably means my next phone will be the Sensation or it's future quadcore brother.
Enjoy whatever you get, I still remember when a six transistor am radio was an upgrade. These are great tech times--

Im just guessing here but your in Canada with bell? bell doesn't offer the nexus one. how are you on a contract? Ill also agree with everyone else your problems are not android related. Sounds like a hardware issue. Good luck with the iPhone my brother loves his. I like the design but that's it.
Just flashed cyanogen latest version. New problems:
1. Sometimes when turning on the phone the lock screen doesn't show up, just my background displays and nothing else. Reboot required by pulling battery out in order to fix.
2. Display menus don't show up sometimes.
3. Already experienced this one, but the keyboard is yet again going completely white.
Anyone want to point me towards an actual working rom without any problems or does such a thing exist

Because not all of these problems are with the hardware and you, or myself are incapable of diagnosing them without more extensive investigation to the handset.
Roms work fine. Your phone doesn't
Most people have no or little problems with these roms
Most if not all issues are improper flashing or incomplete wipes--like not wiping system and data and caches multiple times
Check md5s
Or, not properly partitioning sdcard
If still issues then the phone has too many bad blocks for the rom and kernal
Ken
After reading your first post again, I think it is your phone and not common issues. I have never had a bad camera unless specifically noted on the OP page of an alpha type rom.
I can tell you how I do my sdcard and prepare for a new rom if you like. If my procedure doesn't work you will never have any better luck flashing with that particular phone.
Sorry
Ken
I'm with Telus on my N1 and i've never ever seen any of the problems you mentioned. I've also flashed alot of different roms/kernels/apps/etc and nothing like you had mentioned.
I did however have an issue that resembles your camera issue. Mine was the GPS causing my phone to reboot every time i used it. I didn't really notice it much until i started using it for GPS nav and such. Tried flashing different roms, going back to stock and issue still came up. Called HTC and sent my phone back under warranty. They told me they replaced the board and i have not seen the problem ever since.
I strongly recommend giving HTC a call and see if you can send your phone in for repairs.
That's what iPhone is for. To protect incompetents like yourself from themselves.
You should be nowhere near a rooted phone.
I have the exact same camera issue. The reason is a date of my beloved Nexus and my washing mashine. So it might be a hardware problem for you as well. Sometimes with some roms the camera seems to work 1 out of 10 times.
Bluetooth, fm radio died as well but everthing else is just fine. Some roms seem to check/use camera, radio or bluetooth during a reboot. Then the rom won't start at all or it makes random problems.
This phone is a beast. 20 minutes in the washing mashine at 60°C couldn't really destroy it. Even between screen and digitizer there was water and I had to disamble the phone three times and dry the parts for one week in a rice bowl to get it to work again.

Got this also, annoying but I'm quite sure it goes along with flashes. Pretty sure it will be normal on stock rom.
Actually mate I think you should upgrade your radio...
I used to have this issue with the camera before, get the latest radio and ur camera issue will be solved.
and the battery as well i guess
as for the keyboard and all the other problems just go to rom manager and flash cm 7.1 rc1 from there, make sure you wipe cache, and dalvik cache
it should solve ur issues
Android is a more technical platform, it is by default that the user likes going technical before getting an android

Does anybody have this issue on their tablets?

Hi does anybody reading this have the similar issue? If so do you know the solution or how to fix this issue?
1. Adobe Flash. A small little issue I've been also having that Adobe flash on my Android gives me issues, when I play a video on the browser it usually takes a couple of seconds for the video to show, sometimes it doesn't so I have to reload the page
2. Ever since I've flashed and rooted my device, on the screen I've been getting a little bit of this wavy thing at the bottom of my screen, almost as if it's loosing power down at the bottom of the screen....If that makes sense.
If you know a solution or is facing this problem, please let me know. Or post the solution?
It'll be a great big help! Thanks and thanks for your time! Much appreciate!
my opinion is:
the flash player, it playing streaming software player flash.....it may lag just a little but its not that big a deal is it really?
the wavy lines, i would say look into of a its a defective tab and if you have receipt take it back for a replacement
i wouldnt say defective tab, have had mine for a year, and after flashing over to tabonney's ICS i get an odd flicker too, as for flash, its trying to render what computers play, with just much less hardware resources to use. Its slow and thats the way its going to be.
My video issues aren't like yours Mkami... But if I might suggest making a full backup, then reflash your rom. Maybe you'll get lucky and the issue will go away.

You know, I've been waiting on someone to mention the odd flicker. Does your tab do it when either, a 3d game or app is running, or maybe on a home screen that has an email widget? And does the tablet seem to still be reacting normally to touch input other than the fact that the screen doesn't show any change? I am thinking about sending my tab in over this for warranty work. I got mine over a year ago too. Sure am glad I paid with plastic, got an extra year warranty for doing it. I just wonder what they are gonna say about the bent corner where it hit the pavement...

With pached bootloader and any rom on this site and stock I got
screen flicker, very poor battery, not so smooth scrolling and host of other gliches. (all compared to ota). Flashed back to stock ota and not looked back. No problems. It seemed to me that the problems are not in the roms because stock had the same problems, it the act of changing the bootloader. Just what I have seen, try it just to get rid of the screen problem, go to ota stock no mods and it will be gone.

You know, that's kind of what I've been thinking. I've been testing by going back and forth between bootloaders. So far that is the best explaination. I'll likely go back to stock again soon. But it seems like I remember it doing it at least once on the stock bl...
When I first updated to ICS, all was well. Within a couple weeks, Flash video got laggy, the browsers got laggy, and I got the occasional screen flickers. I backed everything up and did a hard reset and it's been great ever since.
I haven't heard a really good explanation for all this, but a good theory is leftover files remaining on the system, or possibly file fragments, are interfering with the OS. A hard reset purges the old crap out... regardless of the explanation, it's known to fix these problems.

Awesome, glad that you were able to get to normal. It didn't help me tho... I might start a different thread for this if it keeps up. I don't want to hijack Mkami's thread with a different problem. Thank you for the help.
Hey everyone thanks for the advices and different problems you guys are facing.
Sorry for my poor explanation... When I mean screen "wave" what I really meant is screen flicker
I found a semi cure for this...Though I don't know about other peoples tablets, all I did was raise the brightness of the screen and the flicker seemed to not show, I must say though that flicker doesn't really much bother me as it does with the flash, but I guess I have to live with it, just a heads up, my tab isn't defective. Truthfully when I do go to stock ROM everything on the device including the flicker goes away, it's only when I flash my device that I notice that, but I am pretty sure there might be a solution for that one or another, because a buddy of mine has the same tablet, which is why I got that a500. I love it and I love android way much more than any other.
Anyways, I hope Flexreaper releases a new rom soon, really am excited with anticipation. Can't wait to see what he has in store for us.
I am going to try that hard reset and fully restoring the device after a nandroid backup and test and reflash and check if anything works with a good
result I shall post up the steps and how to fix this little issue.
I thank you all! Please post if anybody else has this issue or solution down! Much appreciated! Thanks! :laugh:

[Q] Impacts of Rooting Nexus 7 - Stability

I'm new to the whole Android thing but I used to install lots of roms on my trusty old Windows Mobile devices over the years. I remember then that trying out different roms sometimes meant things would stop working.
Here's my problem. I have a Nexus 7 and it works fine on stock unrooted 4.1.2. I think. I've used the Nexus Root Toolkit to (very easily) unlock and root it. When rooted on stock rom (4.1.1 or 4.1.2), it takes a couple of seconds to turn on from sleep, sometimes needs to reboot, sometimes the gyroscope/acceslerometer locks and doesn't work as it should...
Is a rooted Nexus 7 less stable/reliable than an unrooted one?

Rooting doesn't make a difference on stability (or shouldn't)
All rooting does is give you admin rights to parts of the phone not accesible without rooted. Basically...
Customer ROM's for the Nexus at the moment (and sorry about this devs but its true) are not yet up to par with the Stock ROM.
Its stable pretty fast and not bad with battery.
Hope this helps.
Right so after lots of erratic behaviour with rooted stock 4.1.2, I unrooted and relocked the boot loader. It was better already but I've also run the Forever Gone thing and it's now working perfectly.
I would like to root again but not at the expense of stability. I had previously use the Toolkit if it makes any difference.

Rooting and/or unlocking the bootloader will have no direct effect on stability. What you do with your device after rooting is entirely a different issue.

This would be true if it weren't a Nexus device. We can more or less compile the same ROM that Google shipped. CyanogenMod 10 in my experience has been rock solid stable, though obviously there are still some bugs, I have encountered none. I also used EOS for a little, and that was equally great.

Nope.
IF you flash a non stock rom and/or kernel, then it depends on what you use. Read notes and user replies.
Sometimes I do get random shut downs when not in use, both while charging and not charging. I am not sure if that is a 4.1.2 issue or if it's tied to the rom I'm using. Have had it happen on two different roms.

I lost the ability to control the music app with my headphone controls after rooting, it didnt happen when I opened the box and played with the nexus
Some apps are written to block rooted devices but there's no way the mere act of unlocking and rooting would affect overall stability.

After a day on stock rom I thought it was settled but no...
The battery drained down and after that it kept getting stuck at the Google Cross animation. I spent a while re-flashing stock rom and eventually it starts up. Sometimes. The accelerator issue remains but it is less frequent.
I contacted Google who put me on to Asus. They are going to send me an RMA number and we'll take it from there.
how do you revert or reset to a factory state???
I´m new with the nexus 7 so really have no clue
To reset your device, go to "settings", then "backup & reset", and finally "factory data reset".
The difficult in waking is something I went through with my N7. I found there is a bug with the auto-brightness setting. If I use the manual option I don't experience any problems.
I rooted my N7 the day I got it (had experience with SGS and Gnex) and haven't looked back. I haven't had any other issues than the "sleep of death".
Hope this helps.

If you mean stock non rooted, then the above will set you back to factory.
If you are rooted, that will not remove the root. You will need to flash a stock image to completely return to stock and then re-lock the bootloader.
I seem to have had more problems if the power runs down. I have turned off the auto brightness and I agree it's better in terms of starting up. I still have the issue with rotation not always working. Also, I notice it takes several seconds for the screen to come on when I press the power button. Is that normal?

Okay now it's getting weird. I got an RMA number and they are due to collect it tomorrow and fix it. Since I got the RMA number it has behaved perfectly. I did make a video of the problems but since making the video I've not been able to reproduce them. The battery is down to 14% now, will see what happens when it is fully drained. One major difference is the power button instantly switches the device on whereas it used to wait a few seconds.
Can hardware just fix itself like that? I'm concerned they'll get it and say they can't detect any problems and charge me for the shipping...
I'll keep on testing until morning but if you guys have any ideas please let me know.

I've used Wug's toolkit to return to compete stock. It will wipe everything. It's a two step process, you will still need to lock the boot loader. Go read the thread in the Android development section.

It's fine, even rooted so have cancelled the RMA. Hopefully it was just a short term fluke.
Several weeks on I have had no more repetition of these problems. I did have a line flicker occasionally before installing 4.2 but even that problem has gone away now. I just don't understand how the behaviour can be so unpredictable like it needed to settle into its new home or something.

[Q] Nexus 4 Random Power Off

As the title states. Nexus 4 random power offs. Has anyone seen anything like this?
Here is the background info:
My parents have Nexus 4 phones as do I. All of our phones were ordered at the same time about 2 months or so ago when they became available again. All phones are the 16GB version. All phones bone stock with just OTA updates, not unlocked or rooted other than how they are shipped. All using T-Mobile prepaid plans.
My phone and my father's seem fine. My mom's however seems to shutdown on its own. It is random. Initially I thought that it may be an issue where she isn't used to a smart phone and isn't charging it enough. It happens though at times while it is connected to the charger. It also has happened while carrying it off the charger.
One odd thing is that when they got the phone they brought them to my house and dropped them off to have me set them up. One had the plastic screen protector with the printing on it from the factory the other didn't. I don't know which is which though now. It is a 50/50 shot if this is the one.
I have been around android since the G1 days and run the same phone. I can't think of a setting on the phone that would power it down at a certain time or period of time. She really doesn't have much for apps and is a very light user.
Not sure what to try but I was thinking about doing a wipe of the phone to see if it helps.
Anyone else have any ideas? If the wipe doesn't help the only other thing I can think of is that there is a physical issue with the phone.
I haven't seen this on my phone but there was a period of time where HD Widgets on my N7 would cause a reboot. That was fixed with an app update. This isn't a case where the device reboots. It is a complete shutdown which I find odd. So I have seen an app cause issues kind of like this. For the most part the apps that she has on her phone, I also have on mine. Well I have way more but there really isn't anything on her phone that I am not also running.
I should add that she has the phone in a TPU case. As we all do. My case design is a little different than theirs but they have cutouts for the buttons. So it isn't a case where the case is pressing on the power button. That could be an issue with my case as it covers the power button but I haven't had that issue.
Thanks
Sounds like it might be a defective battery...

That is what I am kind of thinking. Either the battery or the smart battery chips. I think I will try a wipe first but like I said but it is odd.

That sounds kind of questionable (fishy) to me... I also have the 16GB version, and I also did the OTA when I got it. But to be honest the stock OS lasted only about an hour before I rooted and started trying out custom ROMs I have not had the issue you're describing though. How are the results from your factory reset?
Also, would you consider putting on a stock-based custom ROM (such as rasbean vanilla) for your mother's phone? If the problem is software based then a reset or a new ROM might yield different results. But if the problem persists it might be hardware and I'd suggest you contact Google about servicing.

I don't want to root and have my mom run a modified ROM. They live about a half hour from me so I haven't tried a wipe of the phone yet and because of the distance I don't want to deal with the issues that sometimes come up when you go with modified ROMs when I am not there. She is a very basic user and this is the first smartphone for my father and mother. Keep in mind they are in their early 70s and not really that strong on the tech side of things. I have to get some time to run over there and take a look at it. Maybe later next week.
I was just wondering if anyone else has had this issue. I think if a wipe doesn't help I will talk to Google. A search really didn't show much other than some people that were seeing a random reboot issue. I have seen apps doing that.
I have been through their warranty replacement process and it is a bit of a PITA. I am on my 3rd Nexus 7 due to hardware issues with the first 2. My N4 and my fathers have been rock solid.
While I have run custom ROMs in the past, I usually run stock until I find a need that requires me to root. Eventually I will probably root and go with a custom ROM on my N4 but

Yeah, I know what you mean. I'm giving my parents my old LG P990 phone and I just put an AOKP rom on it. I also installed Nova Launcher for them and configured it so there's just one texting app and one calling app the one and only one homescreen. No dock either, just in case they click something by accident or get lost in the app drawer
Since you have the same phone as your mom, a self-less workaround would just be to give her yours (pre-configured), and then you can fiddle around with the problematic one until you find a decent solution. :good:

Hmm. That is a good idea. The PITA part would be to get everything loaded from my phone to hers. I really wish I could run Titanium backup without root as it would make it super easy to move the apps over. Though I don't have that much loaded on my phone. Things that are a pain to set up have configuration export methods like Tasker. It would rule out the end user being the source of the issue. I don't think that is it though. If we swap and it goes away, then I can consider the wipe as the solution. If the problem moves to me then it is a physical issue and call Google. If the problem persists with her, I load all her apps on the phone I carry as well to see if I start to have the issue or it becomes a training issue. The thing I like about this the most is that it is a clear process to rule out several things. I can go over there and sit with the phone but if it doesn't power off when I am there I don't gain much other than spending some time with my parents.
I don't think this is an issue but I did have to provide my IMEI# when doing the activations. In the past though on T-Mobile I have handed phones down to others and all we did was a SIM swap. I would imagine that is the case here.
Oh and one thing I did leave out. They were using their old cell phone chargers on the N4 phones. I told them to swap chargers and use the ones that came with the phone. The old ones may not put out enough power and the phone could in theory run down to the point where it shuts off and slowly charge from that point and I don't think it would turn back on. Keep in mind a retired user who just had a knee replacement so she is at home more often than not.
Did you find out the cause? I have the same issue happened twice today
The random shut off either charging or not happens to me but as mentioned before in a related thread, a lot of the times it also happens on Wi-Fi, and having WiFi optimization on.. purple were turning that off and some fixed the issues. This is my second nexus 4, so I right id give it a try and not use wifi and hasn't happen since I received mines on the 4th of may

So you're saying it's a software issue?
Looks like it.. Turning off optimization or not even using WiFi at all worked..

If Nexus6P got bootloop and fixed, Will run 8 cores again after update to Android 8

I fixed my phone follow link https://www.xda-developers.com/nexus-6p-bootloop-fix/. Now my phone is back but I was wondering how to bring phone run 8 cores instead using 4 cores is very slow and sometime freeze. Is there any way to fix performance?
Maybe Android 8 will fix it ?
Thank you.
AFAIK the answer is no, it is not related to Android.

No. The bootloop "fix" is a workaround that permanently hobbles your device, allowing you to make backups and remove any photos/data you need from the phone so you can transfer to your next phone. Since your phone has a hardware defect directly related to the motherboard, there is no software update that will help. Take everything you need off the phone asap and start looking for your next phone.

Um...no? I mean, it's not that it hobbles your phone. And it's not that it's just a workaround to make backups. In fact it runs almost the same. Turns out, after some digging in, @XCnathan32 found out that even a normal 6p was throtling it's 4 BIG cores from 2ghz to 800mhz, because of which the phone was heating up and marginally running better as compared to the current fix. Now it doesn't heat up and runs slightly lower (not even noticable) than what it used to.
My phone, for one, works almost identical. No dip in performance for my usual activities - no games. Occasionally I run Drastic DS for some emulated NDS games. Never had a bootloop since.
As for the original question: the bootlooping will still occur. It seems to be a hardware issue as far as what I've followed in XCnathan32's posts.
The same link that OP has, will take him to the fix with the flashable Oreo kernels as well.

Have you heard reports from people that got bootloopd again after applying the 4 core fix?

I haven't read any such. There may be. I believe the best person to answer this would be the creator of the bootloop fix, since people with such issues would PM him.

So the boot loop issue has been definitively identified as a hardware issue then? I just got paid out for my Square Trade insurance on my 6P and was considering going back hoping against hope that O would finally fix some of this stuff. Damn shame...

BLOD is a hardware defect plain and simple. No software upgrade (or workaround) will ever change this but not all devices are affected. I think the chances of you finding a NEW 6P are pretty slim... but still possible. We have two 6P's that are approaching 2 years old and no sign of battery degradation or any other issues. I wouldn't touch a refurb at this stage. Probably the best bang for the buck would be a Pixel XL, now the new ones are in the pipeline, prices should be dropping significantly.
I get alert to update Android 8 today. It's worth to update?. Anyone who has experience update the phone with patch fixed bootloop. Is there any concern?

If your device is stock there is no concern and yes, you should take the update . If you had the bootloop issue and needed to apply the workaround to your device to get it working, then you will have to wait because the update would overwrite the fix.
