Nexus 7 (2013) stuck Google screen - Nexus 7 (2013) Q&A

I have a Nexus 7 (2013) stuck on the Google screen, like so many other people. I need some advice please from those who know more that I.
Power + Vol down brings the 4 options Power Off, Start, Recovery, and Restart bootloader. each leads to stuck screen or blank. I have reseated the flexible cables inside, with no change.
Command: "Fastboot devices" recognises the tablet and gives the serial number 07f3ddc1.
If I use Fastboot oem unlock, the tablet screen changed to "Unlock Bootloader" with options Yes and No. (see screenshot). I selected Yes. Wait forever erasing userdata.
Fastboot -w tried.
A response said the userdata had been successfully erased. (If I try oem unlock again it still responds with erasing userdata, but I presume it is then trying to erase what is no longer there).
Although it says "Erase userdata but not formatting automatically formatting", (see screenshot 2), I have obtained a response which says the formatting has been done, with details (see screenshot 3).
User data loss does not matter, my files were all copied to laptop ( Lenovo at the time. Now using Dell with Windows 10)
My question therefore is: If the reformatting has been done, does this mean that the Operating System is no longer in the memory, and I will have to sideload a new image?

[Q] Help with Nexus 7 2nd gen - Bricked?

Hello all
Trying to figure out some issues with my nexus 7.
I was loading up a game, and hit back. The device froze, and I attempted to reboot. Would freeze at "google" screen.
I've tried to do a factory reset via recovery mode, and it simply returns that it cannot mount the partitions, with the "invalid argument" as the reason.
I've attempted to manually wipe the directories via fastboot, but it always fails with the same error. Invalid argument.
It would appear my file structure is gone, and I cannot load the stock because when I attempt to unlock my fastboot it freezes on removing "userdata"
I've tried 3 PCs, all different cables, usb 1,2 and 3. I've used the Asus USB drivers, and the universal. I've tried Wugs methods, which simply render the same error, just quicker.
adb sideloading also fails. It just seems I cannot get anything to write on the sdcc.
fastboot oem ? - fails
fastboot oem h - fails
Only thing that works, is the listing of the device in adb/fastboot - It will prompt for the unlock, but once hitting yes it freeze. Sat for 2 hours, nothing.
Any ideas?

Root Filed- need advice

Hi, I am a Nexus 7 user and was tried to root my device using the Toolkit v1.8.2
I am not experience in rooting Android machine, this was my first time and unsuccessful. My device is now could not be started up.
The following is all information I summarized for this exercise, and would like to seek all advice on the followings.
--1 Is my device "recoverable" if yes, how and what do I need to do please?
--2/ or is it definitely "bricked" so I have no chance to recover it at all.
I am totally in-familiar with rooting machine and I have no access to Linux machine.
Any advice is welcome.
Thx in advance.
Machine: Nexus 7 v2- wifi version Android 4.4.2, Build - KOT49H
Computer: Windows 7 64 bit system
Nexus Root Toolkit v1.8.2
Worked procedure:
1/ Follow the "Initial Setup - Full Driver Installation Guide- Automatic + Manual"
Step 1 to Step 4, install the drivers on the computer. and "Full Driver Test" passed
2/ Click "Unlock", pressed "Y" to proceed. - Device went into a screen asking me to select and confirm, I used the "Vol +" to select "yes" and pressed "power" to confirm, but nothing happened on both computer and device after the "power" switch was pressed. Instead, it freeze the device. nothing is responding even after 10 minutes.
3/ I have pressed the "power button again for 5 sec. and device shutdown to black screen.
4/ Since then, every time I try to start the device, the machine first show a "Google" , then a "rotating flower pattern" and won't started. i.e. - "the flower pattern" keeps looping.
5/ on the computer side, no matter what command is given in Nexus Root Toolkit, a notification of ADB device was not found error comes up.
Consequence
A) Device can be switched on and off by pressing "power" button. when switch on, it display "Google" , then a rotating flower pattern, and never end.
Switch the power button for 5 sec again, device switch off.
B) When device is off, press 'power' and "vol -" will switch on the device to a menu with a robot lay down, options "Restart bootloader", "Recovery mode", "Power off" and "Start" can be selected.
C) For "restart bootloader" the screen goes black for 2 sec, then the menu appear again with "Start" option. i.e.- no error no message
D) For "Start " - the device just just act like normal start, end up in a looping rotating flower pattern.
E) For " Recovery mode" - device screen goes black for 3 sec. show "Google" then show a dead robot with an exclamation mark on it, message " No command" is showing. - After awhile, device restarted and end up in the rotating flower pattern.
F) When plugged in, Window 7 can detect the device, when teh device is in the menu, "Android Bootloader Interface" is shown in Windows Device manager, when the device is starting, " Nexus 7" is detected in Windows Device manager but not both.Hi, I am a Nexus 7 user and was tried to root my device using the Toolkit v1.8.2

I'll take up the task to help you. You are not bricked. You are stuck in something called a bootloop, which is basically when the device enters the boot sequence, but never finishes. The flower pattern that you are looking at us called the boot animation. The computer never recoginizes the tablet through ADB because the tablet never gets to that point.
The screen with the Android laying on his back is actually the bootloader itself. That's why restarting the bootloader brings you to the same screen. I actually want you to be in the bootloader screen. You already have the Nexus 7.2 drivers, so you're ahead of the game.
You also need to visit here to download TWRP 2.7. You also need to put the file in the same directory as the fastboot and adb files.
You need to boot into the bootloader, and run the command:
fastboot flash recovery <recoveryname>.img
This should get TWRP onto your device. You can then download a rom of your choice to put on the tablet. Since you will not have access to place files on the device through USB, you will have to sideload it. First, let's get recovery working, then come back to me if you need help sideloading the rom through ADB while in recovery.
Dear aarsyl,
Thx for your help and it is much better to know my device is not "bricked". Thx again!
Thx for your detailed explaination and I feel much better by knowing a little bit more on what is going on.
>>>>You also need to visit here to download TWRP 2.7. You also need to put the file in the same directory as the fastboot and adb files.
[I also found it in my computer already .\WugFresh Development\data\Recovery_Custom\TWRP
but I downlaod it again from your link and put this file in the same directory where I find the fastboot.exe and adb.exe, which in my case is .\WugFresh Development\data\ ------ done.]
>>>>You need to boot into the bootloader, and run the command:
[- I supose you refer to my Nexus 7, so I will switch it on with the "power button + vol -" button. and get it into the bootloader.]
>>>>fastboot flash recovery <recoveryname>.img
[Here I got an query, what image file I need to use? is it the <openrecovery-twrp-2.7.0.0-flo> ? Do I neeed to run it as an adminstartor in Window 7?
so, do u mean I need to type: fastboot flash recovery openrecovery-twrp-2.7.0.0-flo.img ?
is it right?--(A)
if not, then I am not sure what recovery file to be used!
I do not have any other img file in package I downloaded previously
>>>>This should get TWRP onto your device. You can then download a rom of your choice to put on the tablet.

Not quite understand it this bit, but as you say. it can wait later.
So assume I do the "fastboot flash recovery <recoveryname>.img and get the TWRP on the Nexus 7.
What do I expect to see from the nexus screen. Does it have any note saying completed, or shuold I expect a reboot of the Nexus.
I think one of the problem dealing with these kind of thing is lack of acknowledgment fromt eh machine so we do not know if the operation is successful or not.

I decided to have a go with the downloaded twrp img file.
I launched the command " fastboot flash recovery openrecovery-twrp-2.7.0.0-flo.img" from a command window as an adminstrator.
The command failed with an error saying (remote: Bootloader is locked)
And when I check the Nexus 7 screen, it does said "Locked Status - locked" in the last line.
photo showing both the computer and teh Nexus 7 screen.
Oh, I hadn't realized that you were still locked. No wonder you're not getting anywhere.
Reboot into the bootloader, and run:
fastboot oem unlock
Follow the screen instructions to unlock the bootloader, then run the command to flash the recovery. I advise changing the recovery name to something shorter and simpler, like twrp27flo.img, for example.

Hi, Nice to have reply from you again.
Ammm. I switch on the device to the bootloader alright. run teh command "fastboot oem unlock"
On teh command window, it said" < waiting for device>
and there is no visible change on the device screen.
It already last for 10 minutes now.
I do noted that both windows are freezed and do not respond to key press and button press respectively. No responds on both the device and computer.
How lond does this process take to show the mentioned "screen instruction"? I don't see one!

wow.. it is unlocked now!
Should I continue to use the "fastboot recover command with TWRP file" as per your advise or should I continue to use the "Root" command in NexusRoot Toolkit ??
It is very happy to see there is progress.. Thx...
please keep coming...
I would go with using fastboot to install TWRP. In truth, to truly "root" your device, you actually need a working rom on the device. Otherwise, rooting will be in vain. Unlocking the device was the most important.

Hi again,
Yes. my device is now boot up as brand new.
One side observation though, every time I issue command through window 7 in a command window, everything will freeze up, (not remember if I unplugged the device) until I press the power button to restart the Nexus 7. Same for the last time when i did the unlock and this time recovery.
The hesitation was how do I know when to do this, was worrying there is still some communication between the two machines if I unplug or interfer, may just disturb the communication and corrupt files. -- I normally give it some 10 minutes before I do the unplug and restart. any comment or advice?
Anyway, the device is now up and running. What is the status now? is it with the original version of software? or TWRP version or what?
The device is now remain "unlocked" - is it ok or I need to lock it again?
You have mentioned to download a "Rom", what about it, it is only need if i want to continue to "root " the device?
Sorry for so much question.
I am so happy to see it comes alive again but really would like to understand the current status of it.
Thank again. aarsyl
To be honest, I'm not entirely sure what the status of your device is right now. I was under the implication that you had no Rom on the device. Since you are trying to root for the first time, then yes, you are on the stock software that comes with the device. If you search your app drawer and find the SuperSU app, then you are already rooted, my friend. If it is not there, then search for SuperSU 1.94 in Google, and download the zip file. Then reboot into recovery and flash it.
In other news, I am happy that you got your device working, and I am more than happy to help. The only thing that I don't do is recommend roms. I encourage users to explore different roms for themelves.

Well, sure I will continues to look up the information from the basic, but at the moment Would you please enlight me for the following 2 questions
1/ Should I uncheck or check the USB debugging tab under Developer options - it will be very good if you would like to explain a little on what it does, so I will have a more l\idea what it does when when do i need them.
2/ As i said, teh device is now unlocked, is it ok to leave it unlock or should i have it lock? - again if you would explain a little more on this that will be marvest.

I'm sorry for the long delay. I got locked out trying to log in after I changed my username twice, and it just got messy for me. At any rate....the SuperSU zip file is to be flashed through recovery. When you boot into recovery, select Install, then navigate through the device to find the folder that the file is located. Follow the screen directions to flash items.
USB Debugging needs to be checked for ADB to work, so.....yeah....leave it on.
You don't have to relock your device unless you have to bring it back to the store for repairs. It only stops you from making changes in the bootloader, such as flashing new recoveries, and I think that most fastboot commands might be blocked. I have never tried to use fastboot on a locked device, so I really don't know. Leaving the device unlocked doesn't make it vulnerable or anything, at least to my knowledge.

Thx for your advices AarSyl,
I have successfully root the device and get the Super user app running by following one of tutorial video.
For the first time, when I start at teh bootloader and conduct a "Recovery", it shows a dead robot again but without "no command". I have to redo the fastboot command in the command window with the TWRP recovery file once again. (but this time is very smooth no need to unplug cable that sorts of thing) then I get into the TWRP menu after "Recovery".

Great. I'm happy that it is working for you. A little tip...download Quick Boot from the Play Store. With one touch, you can power off, boot into the bootloader, boot into recovery, or reboot Android.

[Q] Unable to boot beyond google screen

Hello all,
My unlocked (for a long time) Nexus 7 stopped responding so I turned it off and on and now it won't go beyond the google screen.I have tried connect it to my computer but windows doesn't see it as a device (usually does) so I can't run any adb commands.
I pressed power + volume down until the menu appears but nothing I select helps. I have left it for hours after selecting 'recovery mode' from that menu and still no joy. I have left the battery completely empty then changed it up again and it still won't get beyond that Google screen.
Does anyone please know anything else I can try?

Does your computer recognize your N7 when it's booted into the bootloader (aka fastboot mode)?

That's the menu with the start/recovery/power off options isn't it? It doesn't detect it at that point either, I'm afraid.

Well, if you've already unlocked it in the past, you should still have the drivers on your computer. You need to select the correct drivers, and it should detect it. Once you've done that, you can confirm this by using the "fastboot devices" cmd to make sure your device shows up in fastboot mode.

Thanks for the reply.
Sorry I'm not exactly sure how to do that. Will they just be files on my PC, what should they be called?
If it helps, I used the nexus root toolkit to root mine.

Give this a try: http://forum.xda-developers.com/showthread.php?t=2588979. Once you have the correct drivers installed, it should detect it in fastboot mode.

Thanks again!
Ok, so it didn't detect so I rebooted the device a few times while connected to USB and it appeared, did some windows instally drivers stuff then the DEVICE booted. Unfortunately the touchscreen wasn't working (happens fairly often) so I rebooted and now it won't get beyond the google screen again and windows isn't detecting it again.
So close!

Well, if it detected it, then you should have the correct drivers. Boot into the bootloader by holding Power + Volume Down. Plug in your device. Open a command window in the folder where your adb/fastboot was installed. The easiest way to do that is to navigate to that folder (default location should be something like C:/android-sdk/platform-tools) and hold SHIFT on your keyboard and right click. The drop down menu should have an option to open a command window in that location. Type "fastboot devices" (obviously, without the quotation marks), and you should see the serial number for you device pop up. That's when you know you can then use fastboot commands successfully.

Great, that worked, it output my serial number. Now we know we can use those commands, what's next please?

Good. The easiest thing to do to try to recover without wiping your data would be to format the cache. Sometimes, your issue can be caused by a corrupted cache partition. So type "fastboot erase cache" and hit enter. Let it do it's thing. Then, type "fastboot format cache" and hit enter. Let it do it's thing again. Then, on your Nexus 7, select "reboot" and see if it boots into the Android OS.

Hooray! This is looking waay more positive! I can nowe boot my device but still have that touchscreen issue (I tend to do this stuff until it sort itself out).
Thank you so much for all your help. Just in case I can't get the damn touchscreen working. How would I use command line to factory reset this thing please?

Great! Well, except for those touch issues... To flash the factory image, check out the OP in this thread over in the Nexus 5 forums: http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701. Although it's for the N5, the procedure is pretty much exactly the same for the N7 (2013) (and Nexus 10 for that matter). Just make sure you have the correct factory image for your device. Basically, after you download the factory image, you have to extract the folder inside the zip. Then, open the command window there, and type "flash-all.bat" (assuming you're using a Windows PC). IMPORTANT: After everything is done running, boot back into the bootloader and boot into recovery. Select "wipe data/factory data reset." After that's done, just reboot and you're good to go.

Nexus 5X lost lock pattern (fastboot found, adb not found), recovery "no command"

Nexus 5X lost lock pattern (fastboot found, adb not found), recovery "no command"
Hello !
So, I've had the same pattern to unlock my screen AND boot my phone for months.
This morning, I can't unlock : I do not remember it, I try to connect the dot "as usual" and then start to think, and now I've got my muscle memory mixed with me trying to figure out what is the pattern! So I try different combination that I think are close.
Then I reboot...
Then... there's this lock on boot time also, I tried a few different combination, and I have only 5 tries left before device WIPE !
- I have installed Android studio, the USB Driver (which I think is the right one)
- I can either boot my phone in normal mode (stuck in the dot patern lock), either in fastboot mode
- From fasboot mode, I can go to recovery, but it says "No command"
- With the SDK tools, I can list my device with "fastboot devices" (and reboot it for example), but I can't have it to appear with "adb devices"
I'll try one or two other time later when I'm tired my patern, to see if i can do it without thinking...
BUT, Can't I remove the lockscreen somehow? I'd preferably backup some files and apps data before wiping it
What do you suggest!?
Thanks in advance
I finally had to wipe / factory reset.
On reboot, he asked me to unlock the phone WITH MY GOOGLE ACCOUNT.
So ... I had to wipe everything, then unlock it. Why, oh why, the boot screen does not have this option!?

Question Pixel 6 Pro stuck in fastboot, not from downgrading.

Hi All,
Apologies if this has already been covered somewhere but I've been scouring the internet for most of the day and come up with nothing.
tldr: My Pixel 6 Pro has been running absolutely fine for 9 months, no issues what so ever through all the automatic updates, I powered it off this morning to apply a new screen protector went to turn it back on and its been stuck in fast boot since with every option that can be selected returning to the same screen. Not been fiddled with, no root nor boot loader unlock.
Simply turned it off put the screen protector on turned back on and it has been stuck in fast boot ever since with a list of things below I have tried;
Restarted, no change straight back to fastboot.
Recovery Mode, no luck same as 1.
Rescue mode and using googles update/repair tool, cannot connect result is the same as number 1.
Restart bootloader, no luck same as 1.
Flashed barcode setting on and off (i know), device state & NOS Production some times change see non error image.
Flashing via android flash tool, boot loader locked wont allow. 'error getting device locked state -1'
Using force options confirms bootloader needs unlocking.
Connected to fastboot.exe on pc.
fastboot devices, correctly recognises the device is connected.
fastboot set_active a, FAILED (remote: 'error getting device locked state -1') message.
fastboot set_active a --force, same as above.
fastboot set_active other, same as above
fastboot reboot --slot a, accepts command with slower restart than normal but reverts to b.
fastboot getvar all, works list in attachments if its is of any interest.
Details of the device,
Contract device from O2 so probably vendor locked.
Was working fine but the past week or so there have been occasions where it wouldn't accept a correct pin, then would after about 5-6 attempts then be fine some time. I didn't pay it too much thought at the time as nothing seemed off and fingerprint was always fine but seems more relevant now.
I'm not enrolled for the beta.
I haven't tried to root or unlock the bootloader.
For the first time I've been pretty boring with a phone and haven't fiddled with a thing.
I don't think I've even had the dev options menu opened on it.
I refuse to believe its bricked itself for no apparent reason but google seems to be failing me or I must be looking for the wrong thing. There must be something I can do via fastboot surely given that it has got some form of communication?
If anyone has any further suggestions it would be much appreciated before I go down the return/replace route.
I assume you didn't have OEM Unlocking enabled before this happened. Without an unlocked bootloader, there is nothing you can do to fix it, because the bootloader will reject any of the necessary commands to reflash the device. If you're still under warranty, seek warranty repair; this is going to require replacing the mainboard, because no one has the necessary tools to perform a low level reflash.
If the bootloader was unlocked, fixing this would be fairly simple because you'd just have to reflash the boot image. But, as I described above, a locked bootloader rejects all the commands that would help in this situation, and there is no way to unlock the bootloader if OEM Unlocking was not enabled.

Kind of sounds like a stuck hardware button, either power and volume that's makes the phone think you are holding down buttons during boot to get into bootloader
Can you press the power button to start the system? If not, try this (it may be useful, but it may get worse, please be cautious) Hold on power button and volume down at the same time for 45s, When you press 30 seconds, the screen should turn off and restart to this interface. Then do it again as above, when it restarts to the interface again, try to press the power button to enter the system.translate form Chinese(simplified)_Google
