Long shot as this shouldn't be possible, but I figured I'd try asking here anyways. Is there any way to unlock a 6P that's pin-locked by Android's Device Manager?
The goal is to get the pictures off this phone. It was my brother's phone before he passed away and I've been holding on to it for the past few months - just haven't had the energy to try to deal with it...
-I have access to the gmail account.
-I tried changing the pin through Google's device manager, but since the phone was already locked, the new pin did not take. I get the message on the phone about the new pin, but it doesn't unlock it.
-Developer mode is not enabled (i.e. USB debugging).
-Not rooted or anything like that and most likely has the latest updates (t-mobile). As a matter of fact, the lock screen says that a new system update has been downloaded.
Thanks.
Try putting twrp in your adb folder, boot into fastboot and use "fastboot boot twrp.img"

The only way I can think of is by installing twrp on the phone. The only way it wouldn't work would be if he didn't have USB debugging enabled, which if he didn't then you might be out of luck... I'm so sorry.

Unfortunately, I am pretty sure USB debugging is not enabled...sorry that's what I meant when I wrote developer mode (I've tinkered with making apps, so I know what it is).
Thanks.
Same situation here and I try to figure a solution for many days.In my opinia the only way to bypass is a modified google account manager ! Could anybody help?
@clappe Just pretty sure? It wasn't mentioned in the OP, so I'll ask. Have you tried to install ADB on your PC and using ADB pull to grab the files from /storage/emulated/0/DCIM/Camera ? That's the directory to the location where the pictures are stored.
Also, to anyone mentioning TWRP. That's a flat out no-go. He stated bootloader was locked. You can't do that unless you unlock the bootloader.
Edit: He didn't say that, I assumed when he wrote not rooted or anything. Can you power cycle the device? Hold power until it shuts off then boot it up again. Do you see a padlock icon under the Google logo right when it starts up or no?
Edit2: Later today (after work, around 10 hours or so) I'll flash my 6P to stock factory images and relock my bootloader. I'll use device manager to pin lock it and pretend I don't know the password. I'll try a few things and see what I can do. Also, you have my condolences. Sorry for your loss.

Connecting the device to a Windows 10 PC, it will recognize the 6P, but using Windows Explorer will show no files.
Running 'adb devices' lists no devices.
When I power on the 6P, first I get the 'Google' text logo, then the colorful 'spinny' android logo, then the 'android' text logo. Then it goes to the usual lock screen (shows the time, background, etc). On this screen are the normal shortcut buttons on the bottom - microphone, padlock, camera. After a few seconds it shows the 'Locked by Android Device Manager' screen, this has a padlock symbol in the middle along with the pin code that I set online through Google's device manager.
Thanks.
Might be worth a shot to try to contact Google. You'll need proof of your identity, and the passing of your brother though. Best of luck. Sorry about your loss.
If you end up not being able to get a rep that can help via email or phone calls; you might have to do a hardmod.

***TL;DR AT THE BOTTOM***
*^*EDIT 2!!*^*
Utilizing Cerberus, I was able to get passed the boot animation into the lock screen, though the Launcher is, for all intents and purposes, nonexistent. However, I was able to install Nova Launcher and can go to a home screen just fine. THIS IS NOT SATISFACTORY. I want to get back to STOCK Launcher, but it apparently does not exist anymore. I've managed to copy over my backup of Launcher2.apk, but it still refuses to acknowledge its existence. Can I get an update.zip that'll reinstall the default launcher from someone? I can boot into recovery via ROM Manager now I suppose!
+++EDIT!+++
+++~~~I have discovered that my problem is not the device being stuck in boot up, but that the boot animation will not cease--as +in the device is actually powered on, just displaying the boot animation like a screen saver. I cannot boot into recovery as I get +the Google splash screen and it never goes anywhere, my bootloader is freezing every time I plug it into my computer, and the +drivers will not install. My computer cannot detect fastboot and I can't connect to the Nexus via adb either. I CAN access internal +storage but that's about the extent of what I can do.+++~~~
Long version:
I decided I wanted to change the App Drawer icon from stock to a Nexus X that inverted its colours when pressed. I found the icon, converted it to png, inverted the colours and everything was going fine.
After a while I finally managed to find the right icons to replace in the system apk file "launcher2.apk". "ic_allapps.png" and "ic_allapps_pressed.png" or something very similar. I simply replaced them with my two icons, installed my modified launcher2.apk, and that was it.
Immediately, my home wouldn't open at all, no matter how many times I pressed the home button. It just would not exit the app I had up. So I started backing and ended up in an infinite back loop. I powered off the device, waited a minute, and powered it back on.
It came to the usual "Google" screen with the unlocked symbol at the bottom, no problems. However, then it started playing the boot animation. The boot animation never stopped. It looped infinitely. I tried resetting the tablet a few times for the same result. It was after 3 am and I had to get up for work in 4 and a half hours. I thought that maybe it was gonna take a while. So I flipped the Nexus over while it was "booting up" and went to sleep.
When I woke up and checked the tablet at 7:30, it was STILL booting up. Obviously I had screwed something up.
Now, stupid me, I had never flashed CWM recovery on my Nexus 7 (haven't had it that long), so all I'm stuck with is STOCK Recovery. I'm pretty sure I can rescue the Nexus by factory resetting it or something similar, but I'd rather try to save it first. All I modified was a LAUNCHER application, so I'm pretty sure the current state of the Nexus itself shouldn't be too far gone. Is there any way to save the Nexus WITHOUT a data wipe? And if the data wipe DOESN'T fix my problem, is it possible to somehow flash a stock ROM through stock Android Recovery?
***TL;DR***
I modified launcher2.apk and replaced "ic_allapps.png" and "ic_allapps_pressed.png" with two customized .png files (which I renamed to their appropriate file names). Now my Nexus is stuck on the boot animation indefinitely. I would like to save all of my data, as a data wipe would be inconvenient, but if I must do one I shall. I am on a stock ROM and a stock Recovery. If a data wipe/factory reset will not save my device, is it possible to flash a stock ROM through regular Android Recovery?
===Related but irrelevant to the problem===
Is it completely impossible to change the stock App Drawer icon to something different? I'd rather not have to get a different launcher app just to create a Nexus theme! I did a little more research and found that I should've modified the "all_apps_button_icon.xml" file as well, but I have NO idea how to do that.
Many thanks,
VonDerThWood.

no need to flash back to stock, silly advice. just flash a custom recovery and flash a stock rooted rom. flashing a stock rooted rom will replace what you messed up on. dont wipe.

How can I reflash the ROM on stock Android recovery? Googling that returns CWM results.
He is suggesting you flash custom recovery with fastboot and just flash over top of what you did thru the custom recovery which you can do as well, what I suggested just returns it to factory state I don't see whats so silly about it I understand he wants to keep his data but worse comes to worse as long as you can get into the bootloader you're fine

youre right about if worse comes to worse. reflashing the factory image should be the very last thing to do, when all other options have been tried. im just trying to save his data
If you don't have fastboot set up you might want to give this post a look he describes how to get it set up.

I don't use custom recoveries and backup my data regularly with Titanium, so restoring after a reflash is really just an afterthought here, to each there own
The problem is not as it seems.
When I plug the Nexus into the computer when in Fastboot mode, it freezes the Recovery. I cannot select anything OR move the selection to anything else. The hell?
I noticed that when the Nexus attempts to boot up, the boot animation gets brighter.
__
Wait, when it attempted to boot up when plugged into my PC, AutoPlay recognized the device as Nexus 7. There is nothing on my screen but the boot animation, however I can browse internal storage.
I cannot, however, connect to it via adb apparently. ADB devices returns nothing.
____
Okay, the problem is NOWHERE near what I thought it was. The boot animation is replacing the lock screen/home screen/everything. I just received an email (I could tell because of the notification noise the tablet made). It is booting up, just not displaying anything passed the boot animation and ADB cannot detect the device. I KNOW it has USB Debugging mode activated and all, but what can I do now?

I usually make backups and nandroids but I've barely owned this device. ;P
Does fastboot detect the device?

Fastboot doesn't detect the device while booted up like this, and when I plugged it into the computer when in recovery/fastboot mode it not only froze the device, but fastboot wouldn't detect it.
I can get into the internal storage (just not the root of the device unfortunately). So what can one do when he cannot connect to the device via fastboot or adb, nor flash a custom recovery image because he can't access fastboot?
This is getting more complicated the more I dig into it. What the hell did I do?
Are you on the correct screen? I see how you are lumping Fastboot/recovery together, Fastboot is used on the screen with the android with his chest open after holding down the power/vol buttons from complete off , has version info/ unlock status in the lower left.. not sure if you can do that in the recovery but that is where I put the commands in
the freezing in the bootloader is a n7 bug. try a few times. try going into the bootloader then plugging in usb, and try plugging in via usb then going into the bootloader. try a few times, eventually you will get it.

You have to be in bootloader for fastboot to detect your device. Once in bootloader, open a command prompt where your fastboot.exe is stored and type "fastboot devices" without the quotes. If it detects it, it should list your N7's serial number.

Fastboot has the "Recovery mode" option but it just gives me the Google logo with the unlocked icon at the bottom indefinitely...which means I cannot access recovery either? Why didn't I notice this before? >_<

Tried 10 times by booting into bootloader first, then 10 times by plugging it in and booting into it while it's plugged in. This is a very...odd bug.

Click to expand...

Now that I think about it, it DID say something about failing to install an unknown driver the first time I plugged it in. Let me uninstall/reinstall the drivers.
____
After reinstalling the drivers (and removing both of the Nexus7 specific ones), I also removed one named "Android", which, coincidentally, is the driver that the tablet is trying to install upon being plugged in. I have tried to reinstall it several times, but it fails each time, AND I just reinstalled the real Nexus 7 drivers.
___
The Nexus drivers won't reinstall now. I even went to Asus's website and downloaded them, but I have no clue how to install it in this format.
Is there a way to open/install an app through JUST the Internal Storage? If so, I have the stock launcher2.apk file right here...I just need to reinstall it! Damn, how can I get to the Root folder without ADB?
Whoa! Stroke of GENIUS!
I have Cerberus installed on my tablet. Since I know the tablet is booting up, just not displaying passed the boot animation, I decided to give it a try.
I started an alarm, which forced the tablet to the lock screen...I can open apps through the Play Store (as I got an update notification) and the like, but I can NOT get to the home screen.
I opened Total Commander via Play Store, but I can't do anything with it. The app that I used was NinjaMorph and I'm pretty sure the only way I can correct my mistake is through that app. What do I do?
Found NinjaMorph in the Play Store, it couldn't fix my problem. Oh hell.
I tried to copy/replace the launcher2.apk file I screwed up with a backed up one but TotalCommander couldn't do it. It was even granted SuperUser permissions. Attempting with Root Explorer.
Success! I have copied the original Launcher2.apk back into the /system/app folder. HOWEVER, I can NOT install it.
Managed to connect via adb! Things are looking up! Now, how to install this stuff...?
When trying to reinstall the launcher2.apk, it gives me the following error:
INSTALL_FAILED_UID_CHANGED
So I tried uninstalling it to no avail. Troubling.
SO! Now what? I am into the device, and any app I have downloaded through the Play Store is available to me, but I cannot go to the home screen. I need to reinstall the original Launcher2.apk!
Retrying NinjaMorph. It supposedly installed my Launcher2.apk. However, I still cannot return to the Home screen. WTF.
I'm going to install a different Launcher. Hope that works!
Success. I can now return home to Nova Launcher. HOWEVER...
This is not satisfactory. I want my STOCK launcher. Anybody know how I can fix this? The stock launcher is acting like it doesn't exist anymore. Is there a way to just wipe THAT data and keep all the other data on my device?? (Though I admit, I do like how I already was able to change my App drawer icon to my Nexus X <3.)
Edit: I see you resolved it. Good job! I'll just leave this here... :good:

You sound to be in Windows driver hell. If you have access to a Linux machine or someone who does, this entire driver mess can be avoided.
You can't install an apk via the MTP or PTP usb interface. You have a few options to fix this, but all depends on getting your drivers sorted.
Otherwise, grab the latest Windows USB drivers from Google - https://dl-ssl.google.com/android/repository/usb_driver_r07-windows.zip and follow these instructions to install them - http://developer.android.com/tools/extras/oem-usb.html
With the drivers installed and the nexus 7 plugged in, try adb devices again. Assuming you can resolve the driver issue, run
Code:
adb install path\to\launcher2.apk

Hi guys,
I recently dropped my Nexus 4 on the floor today and the screen cracked. As a result, the screen is completely unresponsive now but I am able to see its display when I press the power button. Could you guys help me/point me in the right direction regarding how to get the data I have on the phone (music, photos etc.) please.
My Nexus is unrooted/stock version. I tried connected it to my laptop via USB, but all it does it charge. I think I might have the USB debugging option enabled (as I remember enabling it before sometime ago). I'm running the latest firmware (5.0.1 I believe). Also the bootloader is locked.
Any help would be much appreciated.
Thanks
EDIT: I should note that I have a Password (PIN) for the lock screen.
I installed android sdk and tried to enter commands, but it didn't work. When I typed in 'adb devices', no serial came up (I checked sdk manager for the google usb driver, and it says it's installed). Also, when I tried typing in anything i.e. 'adb shell' it said error no devices found. I was attempting to follow a guide to set up adb for any other steps required to get my data from the internal storage. Bear in mind, I don't have much knowledge on these tools, all I'm doing is following any guides. Please can you help me how to get my photos or the contents of the sdcard.
The pin is not letting you boot into the os and that's why adb isn't working. Can you get into the bootloader? If so boot into twrp then try adb
fastboot boot twrp.img. Where twrp.img is the full file name.

Thanks for responding. I can enter the bootloader (if that's the Volume Down + power button menu). Quick google search shows that twrp is for customer recovery. Bear in mind that I haven't unlocked the bootloader or installed anything like recoveries before (it is basically a stock N4). Would I need to install it? If so, please could you direct me to a tutorial or guide me step-by-step on what to do as I don't have too many ideas on what to do to get the data from the phone.
Just to clarify: My N4 is completely stock, Bootloader is locked (says 'LOCK STATE - locked' in bootloader menu) and it is unrooted. I remember having the USB debugging option enabled the last time I was in the dev menu on the phone.

We'll you've got a problem. You'll have to unlock the bootloader to run fastboot commands and that'll completely wipe your device. And with the pin and an unresponsive screen you can't get into the os. There really isn't anything you're going to be able to do to save your files. Sorry about that.
Edit, just one more thought, are you still on 4.4.4? If so there may be a hope. Shoot, you'll need to boot into the os though. So my idea isn't going to work.

Ah that was what I feared ... I'm running the latest firmware (5.0.1). I wouldn't really care about the phone if it weren't for a few images (should have had it backed up!).
Now I need to decide whether or not to change the screen etc. for £35 or just look in the market for a new phone. If I did buy a new screen/digitiser/frame thing, would these be suitable (where I won't need to use heat guns or glue and stuff)?

Also, if I did change it using the above, would dissembling the phone and reassembling it cause my data to be lost?
Thank you for your help
Edit: I managed to save about 80 photos which were probably in the default images folder in the SD card using AndroidLost. I'm guessing the other images which were in other folders i.e. WhatsApp Images etc. aren't recoverable using the site
So tonight my phone randomly froze and restarted itself, and is now perpetually stuck on the black screen with the white Google text. Every so often it restarts itself back to that point and stops. I was running Nougat from the beta program workaround.
I have done tons of research and am at a loss. So far I have:
-Booted into fastboot mode and attempted Recovery Mode. I can navigate using the volume keys until Recovery Mode shows up in red, but when I hit the Power button to select it the phone immediately boots back to the normal Google logo loop.
-Tried to flash a stock image via command line, no luck because of bootloader I think.
I might not be using all the right terminology, but it seems to me that I am stuck because I never enabled USB Debugging or Unlocked my Bootloader while the phone was working?
-If I go to CMD and type 'ADB devices' I just get a message saying "List of devices attached" and nothing else.
-If I type 'Fastboot Devices' then my phones serial number appears and it says fastboot next to it.
-If I type 'fastboot flashing unlock' it says "FAILED (remote: oem unlock is not allowed)
Does anyone have any ideas on how to fix this and get my phone working again?
Thanks in advance!

Lesson #1: always keep your bootloader unlocked.
Don't bother trying any fastboot commands, they will never work because your bootloader is locked. Don't bother trying any adb commands either, they won't work in fastboot/bootloader mode (they only work while booted into Android and in recovery). I hate to say it but you're basically screwed. With no access to fastboot, no access to recovery, and no access to there's literally zero you can do. This should be covered under warranty, though. When you say the Nougat "beta program workaround" what exactly do you mean?

Don't bother trying any adb commands either, they won't work in fastboot/bootloader mode (they only work while booted into Android and in recovery). I hate to say it but you're basically screwed. With no access to fastboot, no access to recovery, and no access to there's literally zero you can do. This should be covered under warranty, though. When you say the Nougat "beta program workaround" what exactly do you mean?

Where if you got impatient for an OTA you could sign up for the android beta program to get Nougat (once it was officially released) and then opt out of the program without having to downgrade back to Marshmallow.
I was worried I might be screwed. I will call google tomorrow and see what can be done, although I am a little worried since I bought the phone from Best Buy instead of from the Google Play store

I'm not entirely sure how it works but I believe you'll need to contact Best Buy. Even so it should be covered by warranty.

In my experience, Best Buy will not honor manufacturer warranties on smartphones; So unless you bought their Geek Squad coverage, they will tell you to contact Huawei for a warranty RMA.
Contact Info for Warranty RMA:
Huawei Device USA
1-888-548-2934 (1-888-5HUAWEI)
Got ahold of Huawei and it was surprisingly easy and fast. They emailed me a shipping label I just have to drop my phone in the mail and send it to them and it will be covered under warranty. Luckily I have my old Nexus 6 to use until they get it back to me
Hello!
My nexus 6P is stuck in a bootloop and I need to get my photos from the internal storage. I am unable to enter recovery mode; when I try to enter recovery mode, the device just goes back to the Google logo. Is there a way to recover my files even if USB debugging is not enabled and my device is not rooted?
Thank you!
Is your bootloader unlocked? If it is then you should be able to flash one of the kernels from here: https://forum.xda-developers.com/nexus-6p/general/guide-fix-nexus-6p-bootloop-death-blod-t3640279 and it'll allow your phone to boot up completely so you can transfer data from your phone to your computer.

How could I know if my bootloader is unlocked? But I think it's locked since I don't remember unlocking it.
While your 6P is turned off hold volume down and press the power key to turn it on. This will put the phone into fastboot mode and from there you can look at the text towards the bottom of the screen. If it says: Device is UNLOCKED then the bootloader is unlocked and you can flash one of those kernels. If it says: Device is LOCKED then your bootloader is locked and you will not be able to pull the info off of your phone.

It says that device is locked. So this means that there is no way to retrieve the files on my phone? Or is it possible to physically open the device then get the internal storage and access it somehow?
The only other way you might be able to get the data off your phone is to get the SoC re-soldered on so that it'll stop bootlooping, but I'm not entirely sure this will work. Other than that I don't think there's any other way to get your data.

Because you are bootloader locked, the workaround of flashing a custom kernel is not available to you. In order to flash a kernel you need to be unlocked, but the process of unlocking your bootloader WILL WIPE your phone and all your data will go with it. There are threads talking about using a hairdryer to heat up the phone before powering it on to put it in limp mode. If you can get your phone to boot up, you can enable USB Debugging under Developer Settings and then try to get your files off, but chances are extremely unlikely because you have to keep the phone hot to prevent it from bootlooping again. Opening the phone to access the memory chips is a non-starter. Lastly, are you absolutely positive that your photos are not automatically uploaded to Photos? Have you accessed (logged into) Google photos and verified they are not there?
Help! I'm in the same situation!

If your bootloader is locked and you don't have usb debugging enabled there is not much you can do. Have you logged into Google photos on your PC to verify your photos are not there? If your data/photos are not the issue and you just need your phone working again, there is another thread on how to do that (with a little luck).
Hi Guys,
I have gone through your messages. In my case bootloader is locked but USB debugging is ON. Also I checked google photos. Some photos are there but camera and whatsapp photos are not there. May I know any work around to get the data ?

Drop down to the stock recovery mode and use adb to pull files to your PC. If you have TWRP recovery installed you can just use MTP to drag and drop files. Photos are located in /sdcard/DCIM/Camera. WhatsApp photos are in /sdcard/WhatsApp/Media.
I have exact same problem as OP and my phone is Locked and I don't remember enabling debugging mode. From reading replies I understand I can't get my data in internal storage. Now what should I do to make my phone boot-up. I don't need my data back. Also I'm confused about flashing Factory image vs flashing OTA. What does the two mean and what should I do?

Have you found a way to recover phone the phone from bootlooping. As i'm facing the similar problem, when I try to boot into recovery, it starts bootlooping, and I can't use that hairdryer method as there is no OS installed in my phone, and top of that, my bootloader locked too...

Sorry, but if you have no OS, and bootloader locked, and bootlooping you are dead in the water. My phone was unlocked so I was able to use the 4-core method. If your new phone is a Google product, unlock the bootloader from day one.
Hello Guys, beforehand, sorry for bad formatting and some english mistakes.
Let me explain what happened.
I was trying to unlock my Nexus 7 bootloader, but I couldn´t get to the Fastboot mode via adb, so I decided to enter fastboot mode by pressing Power + Volume Down button, but I did this while my tablet was connected to the PC, and after that, it shut down and just don´t turned on anymore. (Never got to fastboot mode)
Now when I connect to windows it only show as an AXP Device and it disconnects and connects when i hold Power button, but never starts.
Also I want to note that.
I didn´t manage to get into fastboot mode.
I didn´t manage to unlock the bootloader.
Didn´t install any Custom Rom.
The device is technically 100% stock, so I don´t expect it to be a Hard Brick, but at the same time, I tried all the button combinations and it still wont turn on.
This happened to anyone? Do you guys have any idea what it could be? Any Sollutions for this?
Thank you.
(Edit: I don´t have the Blobs.bin file in case i need to use the Nvflash.)

Take a look at this comprehensive listing of Nexus 7 button presses/interrupts. They may be of some use...
https://forum.xda-developers.com/showthread.php?p=37606945#post37606945
Hi, Gabu1405...
APX mode is never a good sign with the Nexus 7. It usually indicates that the bootloader has become corrupted, erased or overwritten (by something that is not a valid bootloader). When this occurs, the device is hardbricked and usually requires a motherboard replacement to resurrect the device, although there is a procedure called 'flatline', but this requires previously generated device unique 'blob' files, which you mention in your post.
Having said all of that though, nothing in your description should have caused the bootloader to have become 'damaged'. In order to erase, corrupt or overwrite the bootloader, your device would need to be bootloader unlocked in the first place, because a locked bootloader prohibits any unauthorised write access - bootloader locked devices can only be system 'modified' by official digitally signed updates from Google, which are flashed via the stock recovery.
Are you certain the Nexus 7 is showing as an APX device in Windows device manager?
What was the battery status/percentage when you attempted to unlock the bootloader? Maybe the tablet just needs a good charge, maybe for several hours!
You don't unlock the bootloader with ADB. Android Debug Bridge only works in fully booted Android and with the stock factory recovery. You need to use fastboot to unlock the bootloader, the command being fastboot oem unlock, whilst the device is in fastboot mode, which you boot into via the Volume Down+Power Button key press combo, as you mention in your post.
How it (may have) got into APX mode is certainly strange, because as I've said, this isn't something that normally happens spontaneously - when it happens, it's often due to people mistakenly flashing an incorrect .IMG file to the bootloader partition, causing the bootloader to be overwritten. A possible explanation is hardware failure, and that the emmc/NAND chip storage has developed a fault, and caused the bootloader to become corrupted. It's worth bearing in mind that the Nexus 7 is now seven years old, and with the best will in the world, these things don't last forever, unfortunately. Components fail and data corruptions occur.
If your Nexus 7 is truly in APX mode, for whatever reason, then I'm afraid it's likely hardbricked, and a motherboard replacement is the only realistic way of resurrecting it.
I can only suggest you try charging your Nexus 7, maybe overnight, or for several hours at least, and maybe try the button presses referenced via the link at the top of this post, and see if you can coax life back into your Nexus 7. It does happen sometimes; a seemingly dead device will suddenly spring back to life, through a combination of serendipity and hitting on doing the right things, in the right order, and at the right time
Good luck, Gabu1405...

Ged.

Sorry, I expressed myself wrongly, I ran the same command as you said, it was fastboot oem unlock and it just said, "waiting for device..." then I tried fastboot oem unlock-go, also the same thing "waiting for device" so I just disconnected the tablet and restarted it and it was working pretty fine, then I connected to the PC and tried to enter fastboot mode manually, and this is when it shut down and never turned back on.
Also, my battery was at 70% at that time and yes, It's clearly on APX mode.
Well, thank you for your reply, now the only thing I got to do is recharge it and hope for the best.
Regards.

Probably not much use until, or indeed if, you can get out of APX Mode... But the 'waiting for device' message is usually an indicator of a Windows driver problem - Windows is not able to communicate with the Nexus 7.
The way you'd normally do things is by first running the command fastboot devices
This command does nothing, except to confirm you have a viable fastboot connection, by displaying your Nexus 7's unique serial number in your Windows Command/DOS box. If this serial number fails to appear, you have a driver/connectivity problem and proceeding on to fastboot oem unlock would be pointless until the driver/connectivity problem is resolved.
Anyway, I hope charging the device helps. I'm still inclined to think that your device is recoverable - it would certainly be very unusual for the bootloader to be borked when it hasn't even been unlocked yet. In the seven years I've been a Nexus 7 owner, and being active on these forums for many of those years, I haven't encountered any reports by other XDA members where a locked bootloader has simply quit working... As I say, it'd be very unusual, but I suppose not wholly impossible.

Well, charged my device for a whole day, and now I tried to do the button combinations which you sent the link, nothing happened.
I thought that my battery could be unplugged or the cable was loose or something, so I opened the tablet and it was fine.
So, I just decided to do the button combinations while plugged into my PC, and I noticed that doesn´t matter which combination I try, the tablet disconnects from the PC and instantly reconnects, but still in APX mode.
I guess it is Game Over for me, gonna recharge it again, and try again tomorrow.
Thanks again.

Hi!
I had a Nexus 7 stuck in APX mode as well. Without the blobs saved you can't do anything. I tried a lot of thigs but nothing really helped. I ended up searching for an another N7 with a broken screen but with a working motherboard online. I was lucky and find one around $15. I swapped the boards and it was good to go.
