I had seen people mention the boot animation and lockscreen pixelation glitches, but hadn't seen anything further since. I think an option would be to just back up all my data and flash the 4.4.2 image files. But with 4.4.3 on the way, I might just hold out for a bit longer.
[Nexus 7 Q&A, Help & Troubleshooting] orpheus1988:
Just realised you were talking about the 2012 model, but I can't speak for that, because mine is still at 4.3 (I think) because of the OTA issues (and me not caring because touch is broken and I already upgraded), so what I meant was I haven't had those bugs on my 2013 model.

Nexus 7 2013 failure

Hi everyone.

I've been garnering knowledge from these forums for years now but it's only now that I've had a problem that I haven't been able to solve through asking Google so I thought I'd ask you guys.

I bought a Nexus 7 2013, 2nd Gen two days ago and I've been loving it.

Naturally I had to get root, so I went through the steps on some random article I googled and of course everything went wrong. After an afternoon of the tablet booting the never ending loading animation I eventually got it working using fastboot -w. I eventually got su (forget what its called in android) installed and it lasted all night playing around with busybox which was pretty fun, but this morning I was copying over some movies to the tablet from my laptop and half way through the transfer, the tablet just shat itself, showing a blank screen. I held down power and vol down while it rebooted and still nothing on the screen but it did show up in windows as a "Local Disk (F:)" with a single file "image" containging a bunch of mbn files and an mdn_acdb.img file.

Unfortunately it doesn't show up in fastboot or adb devices :(

Does anyone know what's happening or have any idea how I can fix it?

---------- Post added at 04:04 AM ---------- Previous post was at 03:42 AM ----------

I've started the process of returning the device to Kogan where I bought it. They seem to understand that it is a hardware fault and will process the return which is totally not what I was expecting :D Is there any risk that they will see the unlocked bootloader and not process it?

Factory Reset

I don't know if this question has been posted here before and I apologize if it is. I upgraded my unrooted Nexus 7 to KitKat when the OTA was rolled out. Now I want to go back to earlier android version. If I do a "factory reset" from the tablet's settings menu, will it bring it back to 4.1.2 or do I need to root?
[Nexus 7 Q&A, Help & Troubleshooting] orpheus1988:
No it will just clear your data will still be the same ROM, until you install another one, I'am not really sure if its possible to go back at all, but unlocking and custom recovery should be necessary imo.
[Nexus 7 Q&A, Help & Troubleshooting] ncfoster:
My stock un-rooted Nexus 7 2012 has been relatively problem-free for most of its life. Recently, it has exhibited some of the common battery problems, though I cannot always say which exactly. In short, it was stubborn about coming on without being plugged in for quite a while. I did fiddle with trying to make sure the battery was seated, but I don't think that I did much on that front.

Today, when I went to use the tablet (which has become a much less frequent occurrence lately, thus why I don't know exactly what is going on with it), it was in the middle of a boot. I wasn't sure why it was rebooting, but I've come to realize that it does the freeze and reboot thing frequently and rapidly. It only seems to get a couple of minutes out of rebooting, before it will do it again. I was able to disable Currents, but I am completely unable to get it to do a factory reset. When I press the button, it is ignored by the device, even though everything else seems to respond as it should (until it does the freeze and reboot).

I am more than willing to root, reset, ROM, whatever, in order to get it to work at its best, but I am looking for the best starting point to get a good result. Is there an obvious known first step to get past this situation? Can I be fairly certain that the reboots will only happen when the OS is fully loaded, and not when performing any sort of format, recovery or ROM installation? That is the part that has me a little apprehensive about moving forward willy-nilly.

Looking at going the F2FS / SlimKat route to get a little better performance when I do get it working, thus why I am doubly worried about the thing restarting in the middle of a filesystem change/format. I assume that I'd be bricked hard at that point.

Thanks in advance for any help.
[Nexus 7 Q&A, Help & Troubleshooting] cptsashimi:
I'm not an expert, but no one else has replied... I believe the bootloops will only be a problem while in android and won't happen while in the bootloader. You should be able to do a factory reset from recovery with no problems. This would also apply to adding any custom recoveries or custom Roms.

Since you don't mind starting clean, trying a factory reset from recovery would be a good start.
[Nexus 7 Q&A, Help & Troubleshooting] VideoSavant:
I've had what sounds like a similar problem, and which I posted about here back in December.

http://xdaforums.com/showpost.php?p=48682258&postcount=706

I subsequently posted about this is another thread here, but I can't find that at the moment. In that other thread, I explained how I was eventually able to get into TWRP recovery and execute a reset, but the same thing that happened when I tried to do the factory reset in Safe mode happened here -- when the N7 rebooted, it took me back to 4.3 and the rebooting behavior I described in the linked thread above. The TWRP reset had no effect on the state of my N7.

In any event, I'm actually happy to hear that someone else is having a similar problem (sorry if that came out the wrong way). Back in December and early January, I probably spent 10 to 15 hours trying to get this problem fixed without success. So, my N7 2012 has been sitting idle, gathering dust. I'd still love to find a way to salvage it and get it working again, so please do post if you make any progress with yours.

Also, feel free to shoot me any questions about my experience with this. Two heads being better than one...

Edit...found my other posts from last year on this problem:

I USB unlocked and re-flashed stock 4.4.2. I am still 100% stock, unrooted. Did not install TWRP or any other custom recovery, though that may be happening very shortly. Just trying to figure out the whole custom version for F2FS, etc. At the moment, it seems to be behaving, though it has really only gotten the initial app updates, but it has been running for several hours. Debating whether to dive into a custom ROM, since I have already lost my whole configuration.

Edit: This is where I downloaded my stock ROM: https://developers.google.com/android/nexus/images#nakasikot49h

If you are going custom ROM I can highly recommend SlimKat. Reinstalled mine about one month ago and I am not looking back, what a difference in speed! :)

Really need some help

Hi All

Hope you can help. My Nexus 7 2013 WiFi only just started going to the google screen and not going any further. I have read multiple threads and solutions and nothing has worked due to i am unable to unlock the bootloader.

I have all files i could find, the nexus tool kit and no go to unlock. I have never rooted it or anything. it just started to reboot once or twice and then the 3rd time would not go bast the boot screen.

Any attempt to restore it, I am met with one of the following issues:

bootloader is locked and then fail, when i attempt to unlock it, I get the yes/no question from the tablet and once i select yes, it stays stuck at erasing user data and goes nowhere else. When i do see an error its FAILED <status read failed <Too many links>>

Tablet is seen by pc, im on windows 8.1 and windows 7 all same outcome.

if i go into recovery and try those options, I get a bunch of errors, see attachment. I get a ton of unable to mount errors when i select any option

Any Ideas, TIA

Fastboot and recovery won't flash roms or update.

I've never had problems like this and I've been flashing custom roms and recovery since HTC G1 days. Maybe you chaps can enlighten me a bit.

I can boot into all partitions of my device just fine, regular system, recovery, bootloader all okay. My daily rom (Vanir), however, has been getting a little bogged down lately so I'm trying to do an update.

I transferred my rom and gapps files to the sdcard and boot into twrp 2.6.3.1 to update, but lo and behold, the files are now missing. All my other files are there, just not the rom or the gapps. Not too worried yet, I'll just use the sideload method instead.

Start up sideload and watch it transfer over the new rom (MIUI at this point, and I factory reset before hand). From the cmd line I can see it going over just fine and the device seems to be accepting it as well. It gets to 100% and starts a quick error free install on the device, but when I reboot, nothing has been changed and I'm back in Vanir. Okay...I'll update the recovery and see if a new one works.

So I boot into the fastboot to update the recovery.

fastboot flash recovery openrecovery-twrp-2.7.0.0-grouper.img

Looks good, no error messages, cmd line shows it has been written, so I reboot into my new recovery, only its not new, its still twrp 2.6.3.1 and everything still doesn't work.

Long story long, I also tried installing CWM instead of TWRP -- didn't work, using adb push to move the files and that didn't work, and every time I seem to just lose the zip files after a reboot or update attempt. In fact, when I boot back into Vanir, all my regular files are there, but even though I haven't removed them none of the rom or gapps zips are anywhere. I am sure they have successfully transferred multiple times, but they never seem to make it through a boot sequence. :confused:

At this point I'm stuck, and wondering about my boot partitions being messed up. Any help you can provide is much appreciated.

Nexus 7 (2012) Driver Issues?

Picked this N7 up on sale at Best Buy a few months ago to have a tablet to tinker with. I've skimmed nearly all the N7 threads on here and haven't seen an instance of this issue being mentioned, I may just have missed it. I apologize in advance if I've posted in the wrong area or this has already been resolved. Anyway.

My N7 is fully stock at the moment and my laptop is running Win 8.1. My N7 will only connect to my computer in Camera mode. When I try to connect it in MTP or Install mode, my computer makes the connect noise but nothing comes up. (Occasionally it will show the new device popup and act like it's locating and installing drivers, but that's about one in every ten times I plug it in and nothing happens afterward) I've gone into Device Manager and I see instances of the tablet in different categories, and I've tried for hours now to locate/update drivers; and I've already installed ADB and tried every single other fix I've come upon. Needless to say this is incredibly frustrating.. I've read about this N7 having issues with the flash memory and my main question is: is there an easy fix? If the fix is difficult, is it worth all the frustration? Or should I just give up? Thanks in advance.

Need Help: My Nexus 7 does not turn on or respond to any buttons combination

My nexus 7 (2012) became unresponsive while I am using it so I pressed the power button for several seconds to restart it. It went off and since then it did not respond to anything.

It is an unrooted nexus 7 using the latest stock android version (4.4.2). I got the the update OTA several months ago and it worked well since then.

I tried the power button for more than 30 seconds, the volume down + power button together and the 3 buttons simultaneously (2 volume buttons and power) and it did not respond.

I connected it to charger (its original charger but not original cable that use since the original one stopped working) for several hours and it did not show any sign of charging and still no response for any buttons.

I connected it to PC and it shows APX mode in device manager and still no response to any button combination while connected to PC. The only thing that happens is that after pressing the power button for around 10 seconds while connected to PC the device is disconnected and reconnected instantly ti PC but no signs of life at all on N7.

I even opened the back to manually disconnect and reconnect battery and nothing happened.

Can anyone help me with this? Is there anyway to get the nexus back to life?

Thanks in advance.

Hi tfar,

I think I have the same problem as yours. My computer recognize nexus 7 (2012) as APX device, in black screen with nothing shown.

I have searched online and it seems like nexus needs unique blob file (already backed file when rooted) in order to bring nexus 7 back to life. I dont have it backed up, therefore I am also seeking help.
[Nexus 7 Q&A, Help & Troubleshooting] poondog:
AOKP allows you to do some of that. Not all though

If you are just rooted, you can use an app like Titanium Backup. But, beware that too changes to /system before doing an OTA can make it fail

I am trying to figure out how to search this thread on my Nexus 7, but have been unable to figure it out. I apologize beforehand if this has been answered.

My Nexus 7 is rooted and I have a custom ROM. The magnetic on/off feature does not work at all. I also have tried it on a stock ROM and it still doesn't work. I originally thought that it was the magnetic case that was defective. I saw some videos on YouTube showing that if you put a fridge magnet near the lower left corner of the screen (in portrait mode) that the screen would turn off when you place the magnet there, and turn on when the magnet is removed. Mine does not do this.

Has anyone else had this problem? Is it maybe a software problem, that resulted from rooting the device? How can I fix it?

I contacted Asus, and they want me to send it in for two weeks so they can look at it.
[Nexus 7 Q&A, Help & Troubleshooting] KidCarter93:
Is there any way without running a custom ROM though?

I did have a look around but didn't find anything relevant apart from that app.

I'm not sure why it's like that but rooting the device wouldn't have caused that. It's likely to be more hardware based than anything else.

Have you tried contacting a repair shop to see if they can find out why it's happening?

At least you should be able to find out the problem without sending it away for a couple of weeks.

WiFi across access points question

Hello. I am new to the Nexus 7 (received mine on Christmas) and also to this forum. I searched for this specific issue but couldn't find anything so I am posting here.

I received my nexus 7 on Christmas and also over the weekend added a second router my network. I am on Verizon Fios. I am green to networking as well. My wireless signal downstairs in my house is very weak so I added a netgear WNDR3700 as wireless only (lan to lan to the primary router through a Moca Bridge). I gave the netgear the same SSID and security setup as my action tec router (the primary router).

When I move from upstairs to downstairs my droid phone switches between the two wifi signals seamlessly and without issue. The Nexus 7, however, doesn't.

Based on what I have observed when I get to the point downstairs where the droid phone switches to the stronger wifi signal (or upstairs if you go vice versa), the Nexus 7 fully resets the wifi signal by totally dropping the first signal and then searching for the second stronger signal, the connecting. While this isn't a make or break issue, it is frustrating as I may be in the middle of streaming a you tube video or music and the connection will drop for 30-45 seconds. When I use the WifI Manager app and test, when it finds the stronger signal, it opens a box saying incorrect password. I type in the password that I assigned to it originally and it connects. It asks this every time I move about the house and find the stronger signal (I haven't changed the password at all).

If I don't have Wifi Manager open, the Wifi triangle goes empty after it finds the stronger signal, then after 30 or so seconds it connects.

I have no issues with the switch with my android phone, so I don't know if this is a known issue with the Nexus 7? And if so do I just switch to giving the two routers different SSID names and using an app like BEST Wifi to switch between the two? I'd rather not do that though.

Thanks!

Hi guys, happy new year!

I think I had read several thread regarding the capability of nexus 7 to capture 720p picture but I don't know how this could be done.

So I am seeking some help here...

I just got my nexus 7 3G last month, so far it has been functioning well. I had a success in installing flash, whatsapp and mms.apk.

I'm now running 4.2.1..

I dont know what a root device mean... and any help would do...

is a rooted device same as jailbreak for apple products...

I am happy if the nexus runs with 4.2.1 and have the 720p capability...

I don't want it to run on Cyanogenmod though... I am happy with stock OS...

[Nexus 7 Q&A, Help & Troubleshooting] RootTheMachine:
As long as you unroot and relock the bootloader, you are fine.

I don't know how to answer your camera question...

But root access basically means you have write access to the /system partition. It is similar to having administrative privileges in Windows. While people often associate it with jailbreaking, it is not the same thing. Rooting gives you complete control over the device, and plus it's hard to "jailbreak" something like Android that was never jailed in the first place! XD
