[Q] Stuck on fastboot, unlocked bootloader, no adb mode - Nexus 7 Q&A, Help & Troubleshooting

Dear XDA Geniuses,
I have a 16gb Nexus 7 WI-Fi. I was using Nexus 7 toolkit 2.0.0 to try and flash my nexus 7 back to the the stock google rom (option 9 in the toolkit.) It seems as if it wiped out cyanogen mod 10, which i had been using, as well as clockwork recovery. My nexus 7 now boot up with the google logo and the unlocked padlock on the bootom. using the volume rocker i can select the bootloader option and get an android figure with his chest open.
this is the only option i can select. my attempts have been:
1)connect it to computer. Windows 7 and Windows 8 will not recognize it, nor let me access it from the command line.
2. Use nexus 7 toolkit, which DOES recognize it in fastboot mode, to flash a new recovery on there. it says that a command failed, and won't let it write to it.
3) install adb and android sdk tools. my tablet won't show up under devices, and I am not sure if it is still in usb debugging mode. command line will not recognize it as an adb device and will not control tablet.
when i looked at this thread it was dealing with a locked bootloader, while mine is unlocked. it also wanted command line operations from the computer, which does not seem to work for me.
i was attempting to do something like this (laptop mag blog how to hard reset a bricked nexus 7) but without my nexus 7 showing up under devices I am not sure what my options are.
TLDR: Nexus 7 16gb WIFI only boots into boot recovery. Using nexus 7 toolkit to recognize as fastboot. otherwise will not show up on computer. no recovery, no boot image.
Thank you for reading.

I went back and reread the thread on flashing and restoring nexus 7 to stock in this forum, but every command I try returns " command write failed invalid argument ". Using android sdk manager i can get it to recognize the device in fastboot mode. my drivers there seem to be working.
edit: I got all the way to flashing the bootloader, but it returned "no such device or address. "

latest progress can be found at imgur slash TAikq
now it is say data transfer failure - too many links. 146.84 seconds.

it was my cable. the cable mounted it in fastboot mode, but would not allow writing. switched out the cable, and we are up and running again. thanks!

Um.... Glad we could help?

Sticky?
Man, I would love to see this sticky posted, or at least a list of errors and fixes stickied. I have been looking for an answer to the same issue for two days. Finding out it was just a lousy cable really really really pissed me off... I'm glad someone figured it out and actually posted their solution, most of these wind up with nothing.

OMG, I've tried to flash my N7 with a new lollipop 5.1 today and got the same issue as described here http://forum.xda-developers.com/showthread.php?t=2724273 then, after 5 or 6 hours of thinking what is going on, I finally found this very old thread and guess what? Changing this sh***ty cable I was using solved the problem.

Use USB ports on the back of your computer, not the front.

[Q] Stuck in FTM Mode?

Hi folks,
My wife dropped her 2-week old Nexus 4 which caused part of the front glass to crack and portions of the touchscreen to be dead, so we had to send it into LG for repairs (at quite a price tag). Fine.
So we get it back, I turn it on, and it's in something called "FTM Mode" (file transfer mode, I think)? I can't seem to get it out of it.
Things I've tried:
Rebooting (have to hold the power button down for 5-10 sec).
Factory data reset (the settings are available through the notification menu in FTM Mode).
In recovery mode:
[*]Start (goes right back to FTM Mode)
[*]Power off (duh)
[*]Restart bootloader (gets me right back to the same screen)
[*]Recovery mode (gives me a little android with its stomach open, a red exclamation point, and says "No command.")​
I attempted LG support, but they asked me to do a few of these (after asking me to hit the "home" button...), then told me to mail it back to them because they probably have to flash it.
So, the obvious question: how the hell can I get out of FTM Mode?
Secondary question: if none of the above worked and I do have to flash the OS, can I flash it myself to default Jellybean? Any idiot-friendly step-by-step guides out there?
Here you are! (I was the one talking to you on Reddit)
Since you can get to fastboot you can just flash the stock image files and you should be fine! The toolkit is in the original dev section but you cannot download the images from it anymore. A few people here have the images though so hopefully someone will pop up with them shortly

No worries! You can use the toolkit without knowing fastboot, I just recommended learning it in case you ever need to flash without it. I believe after you download the toolkit there will be a folder you can place the stock image into then you can use the toolkit to flash the image from that folder. I'm not 100% what folder that is though but I believe the name makes it fairly obvious if you look for it

Unfortunately, I haven't even been able to install the bloody USB driver, so fastboot/adb can't even see the device. I've described by problem here. I think the source issue is what LG did during repairs... the device is named "Full JellyBean on Mako" instead of something like "Nexus 4", so the drivers in that post aren't being recognized by Windows as valid for the device. At least that's my guess.
OK, got it all fixed.
This post was incredibly useful. Once I got the USB drivers installed and fastboot recognizing the device (oddly, adb wasn't able to), it was extremely smooth unlocking the bootloader and flashing the image.
Thanks!

For future reference ADB only works in recovery and when booted into android, never in boot loader. Bit glad you got it working

[Q] Nexus 7 (2012) unlocked, but unrooted: waiting for device

I had an unlocked and rooted Nexus 7 (2012) with Android 4.2. After on OTA-Update I have an unlocked but _rooted_ Nexus 7. I read a lot about "waiting for device", but can't get it work anymore to connect. The device is reset and contains a fresh install without any added data.
I tried to follow http://forum.xda-developers.com/showpost.php?p=44179882
Step 2: Reboot the Nexus 7 into fastboot mode using the combination of volume up, volume down and power buttons

I can't get into fastboot with 3 buttons, but with Power and Vol- I see:
Product-Name - tilapia
Variant - tilapia
HU Version - PR
Bootloader Version - 4.23
Baseband Version - 1231_0.18.0_0409
Serial Number - ....
Signing - not signed yet
Lock state - unlocked
Maybe I am doing something wrong then, when I try to flash.
I see start, when I press the power button the N7 starts
When I change to recovery mode, I see "waiting for device" (USB debugging is on, the cable worked to unlock it)
Since I have an unlocked device, I tried only from Ubuntu 12.04 as root:
Code:
~# fastboot-linux flash recovery CF-Auto-Root-tilapia-nakasig-nexus7.img
Before I followed http://forum.xda-developers.com/showpost.php?p=44179882 I flashed recovery-clockwork-6.0.0.6-grouper.img
I could also install SuperSU 1.51, but root doesn't work and I found no way to install an updated SuperSU 1.51
BTW, I didn't know, that the grouper.img is the wrong one for my 3G device, UMTS worked fine with 4.2
try using nexus root toolkit. I had rooted prior to 4.3. when I updated, i just had to press one button to reroot(if you didn't use nexus root toolkit to begin with then you may need to go thru the driver setup)

Where do I get the drivers? Couldn't find a link there.
Edit: Since I have to go to a Windows PC, I downloaded the windows-programm only on my linux pc, it looks like the drivers are included in Nexus Root Toolkit: http://www.youtube.com/watch?v=iQhyerPfGes
I tried a lot with Windows XP 32bit and Windows 7 bit, but always I got "adb device was not found", but I saw a popup on the windows desktop with the Nexus after I attached the USB-cable. With Win7 I tried drivers 1-3, with XP driver 1.
With Linux something works:

This forum is for the new 2013 Nexus 7 named Flo. You stated you have the 2012 verson...might want to go to the 2012 Nexus 7 forum here for advice.
On the 2013 Nexus 7 I use the volume button in bootloader/fastboot mode to switch to recovery, then select it with the power button to boot into the recovery you just flashed to the device. From there you can install Supersu (if you have downloaded the Supersu zip file to your device before hand).

Oh, I am sorry to be in the wrong forum. What I found out in the menatime, that the stock-recovery is flashed everytime after a reboot, so there is no menu to flash zip-files after a new start.

I know it was in the wrong forum and all, but found something odd. I had a lot of trouble due to the same thing, waiting for device when trying fastboot. Just in case anyone arrives here: When you see the screen with the Start on top and FASTBOOT MODE in small red letters with the product specs, you're exactly where you should, no need to choose any option.
In my case, the fastbood mode doesn't work from linux (Kubuntu 13.10). It's just not detected, it makes no usb plugged sound, no icon on the tray...nothing. After some headaches just decided to boot to windows and try again. Fastboot mode, exactly as described, plug it to USB, and there you go, the "bop-beep" sound of usb plugged. I knew then it was gonna work on Windows.

That symbol is a security feature within the stock recovery, volume up and power to access the stock recovery.

For me also Stock recovery never worked. Just try to flash CWM or TWRP.
Btw, What toolkit did you use and how did you install the drivers. Please answer these, so that someone can help you better.(Or is it just the 'mac toolkit' ?)
My suggestion: PLZ DO NOT USE TOOLKIT. If you are stuck at some point while using the toolkit, then you'll not know what went wrong and how you can correct it. Do it manually. It is the most hassle-free method. Trust me.
I think that ADB will not work in stock recovery(may be you can boot normally into your phone and then try adb). The thing which you are looking for is 'fastboot'.
1) Restart ur phone (Power Button + Volume Down, i guess) and land in the bootloader and connect your phone to PC.
2) In CMD prompt(or Terminal), type 'fastboot devices'. If your device gets listed here, then fastboot is working and drivers are properly installed. If not, then drivers are not properly installed in your PC. You need both ADB and FASTBOOT drivers. Install them properly.
PS: For MAC, i think the command is slightly different. Something like './fastboot devices' . Please look for the same in this forum or just google it and find out.
3) Follow this guide for flashing CWM and Rooting.

4) For properly installing the Drivers, read " A. Install the drivers " in the below thread (actually you can read the entire thread )

I used the nexus 4 Mac rootkit I found in here.
It unlocked my phone fine. But when it came to installing a recovery and root it didn't.
Neither my adb or fastboot are working now before I unlocked and I messed around and they worked now nada ...
I went to YouTube saw my problem tried pressing volume up and power like in the video and it just gives me a black screen and either turns the phone off or reboots it normally...not sure if in supposed to hold power and let go of volume or vice versa.
I placed all the files on the storage I just need to access stock recovery which I strangely cannot now...
Tried framearoot and got nowhere.
Very frustrating

Just as I mentioned, i also had the same problem with stock recovery. So I simply flashed a Custom one(CWM, in my case)
Get the ADB and FASTBOOT working and that'll solve your recovery problem. Try fiddling with your drivers again. Not sure how to do that in MAC. If FASTBOOT is working, the you can boot into a Custom Recovery(you need not even flash it) and perform whatever you need to.
fastboot -c "lge.kcal=0|0|0|x" boot customrecovery.img
Again, look at the efrant's guide i referred above; i took this from there only.Remember to replace 'customrecovery.img', with the actual downloaded custom recovery image name.
Or you can try posting your problem with the toolkit, in mac toolkit's thread.
I have been youtubing everything and finally got to
Reboot system
apply update from adb
wipe data/factory reset
wipe cache partition.
I now can get adb working so I tried ./adb sideload cwm from my desktop and it is giving me signature verification failed. installation aborted.
What can I do to resolve this?
I searched xda and no one can solve this issue from the threads I've read.
I fixed it! Whooohoooo! Installed cwm and root ....now to install pa rom.
Thanks for the help!

[Q] Installing Custom ROM on Wrong OS Version, Looking for Solutions

I apologize if this question has been answered already, but I just spent 15 minutes using the search button and could not find a response.
I just installed Matr1x v10.5 (http://forum.xda-developers.com/showthread.php?t=2007231) onto my Nexus 4 but it had JB 4.2. Based on the version notes of the thread, I assumed that it was backwards compatible with my phone and therefore installed the new version on my Nexus 4. Now every time I turn on my Nexus 4 the screen is blank. What can I do to fix this issue? Will it require a reset so that all my data is lost? Thanks.
What do you mean with '... The screen is blank'?
Can you get past the google bootanimation?

Nope, basically once I turn it on I see the "Google" text, and then the screen goes blank as in it's black. Basically the back light is on and you can see that it's on but the background is still black.

Go into recovery and flash the stock kernel. If that doesnt work you need to do a full wipe and reflash the rom.

Theoretically, if I flash v10.0 (which accommodates JB 4.2) it should fix the issue right?
I'm at a dilemma because I do not know if there are any other ways to insert the kernel into my phone as there is no microSD option on the Nexus 4. Does anyone know how I could potentially get the file into my phone?

I had already tried that, but once I connected my usb into my laptop I still couldn't transfer any files over.
In the end I reset my phone to factory settings, so the display still shows "Google". Just to confirm, the reason why this logo has been displayed on my phone for a while is because it is working to restore the factory setting (e.g. OS) correct?

I can't tell for sure since it never happend to me but I don't think if you choose to reset your phone to factory settings it will stay at the google logo.
If you choose to reset to facory settings I think you just will boot into recovery with that an android standing with something in his belly with a loading bar.
You can try this.
1.Boot into bootloader.
2A.Flash TWRP with the fastboot command and go to step 3.
2B.Flash stock N4 image with the fastboot command and profit!
3a.Try to mount storage and transfer another rom.
3b.Restore a backup.
Hopefully this works.

I have tried the above instructions up to step 3 because it did not work for me.
It shows the only files in my internal storage(/sdcard) are a file that says (Up A Level) and TWRP. Also, whenever I want to reboot it prompts "No OS Installed! Are you sure you wish to reboot?" At this point I am only interested in a factory reset now so that I can reinstall the initial JB 4.0 that came with the Nexus 4 and then upgrade to JB 4.3. However, whenever I do factory reset via recovery mode, I am stuck with an empty phone with the files I mentioned above.
What can I do to fix the situation? Thanks.

I think the reason that a factory reset won't help since there is no OS on the phone so it cannot reset something that isn't there.
And with the steps I mentioned, can you get into bootloader or does it directly boot into recovery.
Another thing you can try(I don't think it will work but I never tried it so you never know)
Download this toolkit:
http://forum.xda-developers.com/showthread.php?t=2015469
There is an option to flash to stock completly, that will maybe do the trick.
Good luck!

I can get into bootloader fine, it does not boot directly into recovery.
My Nexus 4 is already flashed with TWRP. I have installed the program from the link you provided, however, I have not used it to flash my phone again as one of the prerequisites to using the program is selecting which OS version I am using (at this point I am not using any) and want to prevent any further issues from occurring.
It seems like I can't really do anything with my phone unless I get a JB OS reinstalled, which is what I am currently struggling with. I am presently trying to find a way to copy the downloaded Nexus image files provided online into my internal storage so I can install them.

I have installed the program from the link you provided, however, I have not used it to flash my phone again as one of the prerequisites to using the program is selecting which OS version I am using (at this point I am not using any) and want to prevent any further issues from occurring.
It seems like I can't really do anything with my phone unless I get a JB OS reinstalled, which is what I am currently struggling with.

Okay since you can get into bootloader thats great news!
Have you tried to manually download the nexus 4 image from google?
NOTE this are direct download links:
4.3:

Scenario #2 on that guide suits you!
I think this will do the trick!

You just have to do the following :
A) flash a recovery via fastboot (fastboot flash recovery recovery.zip)
B) now go ahead and boot from your recovery, and push the rom of your choice, in case you don't have one already inside your sdcard (adb push ROM.zip /sdcard/ROM.zip)
C) flash your recently copied rom of choice to your phone. (if necessary, wipe data, cache and dalvik cache)

I just spent a couple of hours reading through the guides (and trying them out) which led me to several other guides. To be incredibly honest, I am completely confused as there is a plethora of new information thrown at me. I have to pose several questions before I continue:
1) When you say bootloader, are you referring to the fastboot bootloader screen that pops up after holding the volume down button and the power button? I just wanted to confirm this as I am starting to feel you are referring to something different after reading several guides.
2) Is the scenario 2 guide you posted basically a method to "sideload" the JB 4.3 into the storage of my Nexus 4 so I can install it via Recovery Mode?
I tried installing the drivers but I cannot seem to do it successfully as I do not even have a starting OS for my phone in the first place. I can not access a theoretical "Developer Mode" either from when I first rooted my phone.
So basically, I do not understand how I can get the direct downloads from Google (the JB 4.3 files) and get them into the internal storage of my Nexus 4 to install the OS.
Is there a simpler way to do this? If not, here is my current progress. At the moment I am stuck at this guide (http://forum.xda-developers.com/showpost.php?p=34552123&postcount=1) from the previous link you linked and am between C-D. I cannot get my laptop to recognize my device via fastboot devices in command prompt (D). To be honest, this is the second time I've seen this guide but could not get it working properly which is why I used the file provided at (http://forum.xda-developers.com/showthread.php?t=2015469) to root my Nexus 4.the OS[/B].

Yes, the bootloader is the one where you press vol down and the power button together, that's the place where you select to go to the recovery, use fastboot.
First thing you got to do is turn on your phone on the bootloader as mentioned above. Then, assuming you downloaded this: [NEXUS 4 TOOLKIT V2.0.0] from here http://forum.xda-developers.com/showthread.php?t=1995688, open up command prompt and go to this address with "cd C:\Google_Nexus_4_ToolKit" or where you decided to install your toolkit. On windows explorer, go there and rename fastboot-toolkit or whatever it is called to fastboot to make things simpler.
Type in cmd: fastboot devices to check if it recognizes your phone.
If it doesn't; then install these drivers (you should have your device already connected via USB to your computer): https://www.dropbox.com/s/a808emeelvxkwyc/usb_driver.rar
Go to Control Panel\Hardware and Sound > Device Manager. Your phone should appear with an exclamation mark somewhere, right click it and click on update driver:
-Click on browse my computer software
-Let me pick from a list of device drivers on my computer
-Have disk
-Browse for where you downloaded the drivers I linked you to then click ok.
-You should find within the next page something that says Android Bootloader Interface, double click it and finish the installation.
After that's done, then type in fastboot devices on cmd again, it should show up now.
Then, go to here and download TWRP 2.6.0.0 http://techerrata.com/file/twrp2/mako/openrecovery-twrp-2.6.0.0-mako.img , that will be your recovery. After you've downloaded move it to C:\Google_Nexus_4_ToolKit to make matters easier.
NOTE: IF YOUR BOOTLOADER IS LOCKED YOU WILL HAVE TO UNLOCK IT , this can be done by typing fastboot oem unlock on command prompt
Now, simply type in this command: fastboot flash recovery openrecovery-twrp-2.6.0.0-mako.img you will now have a recovery on your device.
With the volume keys, choose to boot from the recovery. TWRP will load, while its loading, rename adb-toolkit to adb to make things easier. When its done loading, type in adb devices to see if it recognizes your phone, if it doesn't use your drivers again but this time instead of choosing Android Bootloader Interface, pick the one that says ADB.
When that's done, and it recognizes your device with the adb devices command you can now proceed to "push" or "copy/move a ROM you've downloaded in your computer towards your phone".
Of course you have to download a ROM, like Paranoid Android for example: http://goo.im/devs/paranoidandroid/roms/mako/pa_mako-3.69-20130722.zip , along with its GApps: http://goo.im/devs/paranoidandroid/roms/gapps/pa_gapps-full-4.2-20130719-signed.zip
You might have to even update your radio and bootloader in the future too, but let's leave it at that for now.
After you are done downloading the ROM of your choice, then type in these commands (assuming ADB works)
adb push pa_mako-3.69-20130722.zip /sdcard/
adb push pa_gapps-full-4.2-20130719-signed.zip /sdcard/
Having moved these two files inside your phone, now its time to flash them.
1) Go to Wipe on TWRP and simply swipe to factory reset
2) Go back and click on Install, look for pa_mako-3.69-20130722.zip and then add pa_gapps-full-4.2-20130719-signed.zip to the queue, swipe to install.
After that's done, simply reboot your phone and it should start booting up Paranoid Android and you're done. Might give you a few issues if you have an old radio and bootloader, but that can be fixed by flashing the new versions of these two in TWRP. Can be found here: https://www.copy.com/s/JniBu/4.3 files (mako) (these can be pushed via ADB like before, or you can simply download them on your phone when its working)
Hope this helps, don't think I can be more detailed.

The first thing I'd like to do before reporting my progress report is to thank you and failly for taking the time to help me out. You both have contributed tremendously in trying to help me out with this, so I would like to thank you both for that.
1) I had installed the sdk program and changed the adb path (following this guide http://www.redmondpie.com/how-to-set-up-android-adb-and-fastboot-on-windows-tutorial/)
Following wammie's guide:
2) Booted into bootloader
3) Downloaded and installed NEXUS 4 TOOLKIT V2.0.0 (had used it before but it didn't work for me so I relied on a different program to root my phone). Renamed fastboot-toolkit to fastboot
4) Typed fastboot devices in in cmd, does not recognize phone
5) Uninstalled current usb drivers and installed usb drivers provided. The driver I chose to install for was titled "Android". The other ! mark was "Base System Device" which was something I had never seen before until today when I had reinstalled usb drivers
6) Typed fastboot devices in cmd again and still nothing has changed
I am unable to continue any further as fastboot does not recognize my phone when I have it under bootloader. I had downloaded all the files that were recommended in your post. I think the reason why I cannot access fastboot devices is because there is literally no OS running in my phone. I could be wrong though.
I guess I'll take a break and call it a night since I've been trying to fix this problem the past 13 hours or so. Any additional feedback and support is appreciated!
Additional Notes: I have tried this both on my laptops (Windows 8) and on my desktop PC (Windows 7)
Luckly, if windows doesn't recognize your device while in fastboot it isn't because you don't have a OS installes but because not correctly set up drivers.
I posted a link some posta ago about a toolkit:
http://forum.xda-developers.com/showthread.php?t=2015469
When opening the program at the top there is a button called full driver installation, press it and follow the instructions.

This is what you should do when you are updating the drivers, its imperative you get those drivers working. Otherwise, you won't get access to fastboot.
Oh I would recommend using a Windows 7 PC.
Windows 8 can also do the trick but you maybe need to disable driver signature enforcement, so you better go with windows 7 for now.

Status Update:
I had spent a whole day reformatting my Windows 7 machine and am back at it. I have made a bit more progress than before.
1) After typing in fastboot flash recovery openrecovery-twrp-2.6.0.0-mako.img in command prompt, under the "List of devices attached" it is blank (i.e. there is no device attached). http://i.imgur.com/TnyBCKS.png
2) I have successfully installed the usb driver on my PC the first time when the only explanation mark was titled "Android", however the only Android option at the moment now is labelled "Android Bootloader Interface". No such thing as ADB (or any variations including Android ADB Interface) exists.
3) In TWRP Recovery mode, I see an exclamation mark titled mako but I believe that is irrelevant. I have tried installing the drivers to this just in case but failed. I then tried it again in Bootloader mode and mako is gone and Android Device pops up again with "Android Bootloader Interface"
4) I have tried restarting my PC and repeating the above steps.
Edit:
5) The only time I see an Android Composite ADB Interfaces is when I boot normally to the "Google" screen. However, I cannot move any of my ROMS over into my phone. When I typed "adb devices" it shows a bunch of characters with offline beside it. I do not have any options to reinstall any drivers for this.
From my understanding,I should be able to access the Android Composite ADB Interface while in recovery mode, which should let me transfer my ROMs over... but the issue is I cannot access Android Composite ADB Interface while in recovery mode.
Also, is there any reason why I shouldn't use the official JB 4.3 img as the ROM I want to install on my phone?

Stuck in Boot, fastboot locked, no adb sideload

Hello,
I have a Nexus 6P stuck during boot on the white google logo. Apparently it happened during an update to N.
I have attempted a few solutions I have found either on xda or on other pages but the gist of what I’ve attempted so far is thus:
I have tried to reflash android stock after obtaining it from google : https://developers.google.com/android/images (MTC19T) but the oem option was unchecked so “fastboot flashing unlock” returns with an error.
I have tried to apply an OTA update, again I obtained the file from google (MTC19T) , via the recovery > apply update from adb . But it fails. The error from the phone is:
Code:
E: failed to verify whole file signature
E: signature verification failed
And on the pc side I believe that the failure comes from the fact that my pc has never been connected to the phone via ADB, so it’s unrecognized.
- I have also tried to bypass the adb pc signature issue by connecting a usb flashdrive to my phone via a usb-c adapter but the mount /sdcard command doesn’t work.
I’ve tried a few more esoteric solutions, like booting into Emergency Download (EDL) but my phone just boots into the google logo and stays there.
A few informations on my device (according to the fastboot/recovery screen)
Code:
BL: angler-03.51
Baseband: angler-03.61
Product/Variant: ANGLER-ROW-WN1
6.0.1/MTC19T/2741993
Current Build Number: MTC19T
So, to summarize: Fastboot is locked and won’t work, ADB is unrecognized and using a usb drive pretending to be an sdcard doesn’t work and I’m working with a stock recovery.
I'm looking for a way to bypass the fastbook lock or the adb verification. Or (even better) for anyone here to tell me that I've been going the wrong way all this time and that the solutions involves three easy steps...
Thank you!

Try again but you have to use an OTA that is newer than MTC19T. You still may be able to sideload when recovery is in ADB Sideload mode. There is no way to unlock your bootloader. Make sure you are using a recent, known working copy of ADB/Fastboot. The problem many people can't overcome is that they never set up ADB before or used it on a few occasions, so now the phone is dead they can't get it set up correctly. When the phone is connected in recovery>>ADB sideload update, what returns when you run "adb devices"? Do you have another phone you can use to confirm your ADB/fastboot setup is installed correctly?
Download the Nexus toolkit and then boot into recovery and select on the toolkit "softbrick" , good luck. Private message if you need any help

Hi,
Thank you for your answers.
@v12xke For the OTA after trying MTC19T I downloaded and tried half a dozen images from Google. Previous versions, next version of marshmallow, a few of the nougat versions. The results were exactly the same.
As for adb I just updated my Android studio, and it's not the first time I've used these tools. The process of sideloading the zip always stops at 47% but I can see that adb and the recovery are communicating.
Fastboot devices also detects my device, but I don't have my computer on me right now.
@DavidSantos I already tried the toolkit but it just launched my phone on the Google logo and got stuck there.

Yes, I did that. The soft just makes my nexus reboot to the Google logo.
@v12xke: Looks like there are also more and more of those bootloader + recovery access bootloop. With sideload OTA fails...
@Hipstronaute: I have already seen one or two users with the same kind of problem and if I remember, nothing fixed the problem.
Good luck...
Might be a special edition Nexus 6P , oh well. Mine had the same problem and it worked just fine

That's too bad. Sounds like the storage memory going bad and the write process is interrupted when it hits that area. Thing is, I've heard the same OTA write failure occurring several times at 47%. Wonder what that means? Anyway sounds like @Hipstronaute is looking at a replacement phone, under warranty or otherwise.
