[Q] Wugfresh stucks on: send bootloader(1280kb)

Well, i tried to install stock Bootloader, stock recovery and stockrom with wugfresh tool under "Back to Stock", and so thats the problem:
When i try to send the bootloader, it stucks and the tablet posts under the infos on the bootloader screen: FASTBOOT STATUS - DATA00140000.
And thats it. I waited 2 hour, it still stucks on sending bootloader. So i downloaded the Unified Android Toolkit, install the fastboot driver and tick the option to install a new recovery... It still stucks on sending bootloader. In Youtube Videos, i saw, that the sending finished about 0,2 s. Thats 1280kb! Why doesnt work it on my tablet. I had root, but i didnt tick the usb debugging. So when i switch on my tablet, it comes to the bootloader, and its the activated bootloader( i can switch to recovery, reboot bootloader, power off, reboot system,..) and its unlocked. If i reboot into the recovery, it also comes to the activated bootloader. Its also when i tick the reboot system. So what can i do? Is it hardware bricked? Or whats the problem? I have the bootloader version MANTAMF01 and the H/W Version 8. Can anyone helps me?
And yes, i am the Admin on my PC

The problem is the toolkit, just use fastboot
fastboot flash bootloader nameofbootloader.img
And your done
But after doing so you effectively wipe a few of your partitions so then flash recovery and ROM as well, the method on doing so slightly varies depending if your going back to stock or what something custom

I am having the same exact problem, and I tried doing as you said with fastboot, but I still can't receive any files. Any other suggestions? Any help would be greatly appreciated.

Are you trying to return to stock? Download the appropriate factory image (just Google android factory image) extract all and flash with fastboot.
If you want more detailed explanation boot to bootloader and write down all info on that screen, pet me know the os of your PC, and the explain a little more what's wrong, I'm not sure what can't receive any files means. It is often helpful to copy and paste all input/output from cmd/terminal

I just resolved this issue on my own about a minute before your response lol. The problem was that I wasn't using the stock USB cord. Holy cheese and rice, I've been sitting here for the past 5 hours at wits end trying to figure out the problem. My problem was exactly like MrCreeper's, it was just stuck on "sending 'bootloader'" with no progress whatsoever on either PC or tablet. Who woulda thunk the problem was simply that I was using the incorrect USB cord -_- *sigh*
Anyway, thank you for your prompt reply. I did use a few of your tips from your other posts when I ran into other problems trying to flash stock image, so cheers for that!

[Q] Nexus 7 stuck at the google logo

Hello,
I've got a problem. On monday my Nexus 7 2012 (with lastest stock Android) froze and I had to reboot it. But then it got in a bootloop where it would boot to the boot-animation (the four moving dots) and then restart after half a minute. Then I went into the bootloader to switch it off. When I switched in back on it just got stuck at the google logo.
I tried to reflash the stock rom, but I haven't unlocked the bootloader yet and everytime I try to do unlock it, it fails with "unknown error code".
At first I used Wug's Toolkit. When that didn't work I used cmd, but that doesn't work either.
I would really appreciate some ideas to solve that

You dont have to unlock the bootloader to flash factory images.
You can flash it with fastboot or a toolkit.

Did you try to get into recovery?
Maybe you can wipe some thing like cache, dalvik cache and system,
And then install the firmware again.
I once installed a firmware without properly wiping and also got stuck in thjis animation logo.
After wiping in recovery and re-flashing the firmware it worked again.

As far as I know, you need to unlock the bootloader. Anyway, I tried a toolkit as well as fastboot via cmd but none worked.
See here: http://forum.xda-developers.com/showthread.php?t=1907796
In order to do anything useful in fastboot, the bootloader must be unlocked

I dont't have any custom recovery installed. When I am trying to access the stock recovery mode via the bootloader then I get to the Google logo and "booting failed" is written in the upper left corner.
My guess is that the emmc is broken

Google search android factory images, download the appropriate one for your device
Then extract contents and double click the flashall.bat
If this fails then chances are your emmc has been severely corrupted, I've seen a few get to that point with the booting failed and its 50/50 if they resurrect their device
Best of luck
(Oh and don't use toolkits)

I tried that again the way you described it and sadly it didn't work. I have to accept that the emmc is corupted.

No Bootloader

Hey, I flashed the new DP4. Now I wanted to revert back to MM but the phone doesn't boot up twrp. It just hangs at the twrp splash screen. Fastboot wont work either. REbooting into bootloader doesn't work. Going for it reverts the phone back to the screen where you see an android laying on its back. Evrything enabled except for download mode. Even clicking on starts doesnt boot up andorid n. Android n only boots up when click either on factory or bp tools?? Typing adb devices via adb only show list of attached devices, typing fastboot devices results into nothing
Any ideas how to get back to twrp.

When you say bootloader doesn't work; what doesn't work about it? Your bootloader should look like this http://www.androidcentral.com/sites...exus-6P_bootloader-unlock-1.jpg?itok=aDeXgpNz
From there you should be able to flash the factory image and get a usable phone back.

Yeah if your bootloader didn't work you would have an actual brick(meaning no turning on and nothing on screen). That's the one thing your phone can't function without. Unplug your phone from PC and then hold the button combo to boot bootloader. Then flash a factory image minus the -w command and then flash recovery.

Your bootloader is fine, if it was damaged your phone wouldn't boot at all. Boot into the bootloader and flash the factory images, details in my guide:

It's hard for me to suggest anything because you haven't given any background on the situation. Here's an idea though:
Flash TWRP recovery to the device.
Enter TWRP, enter the wipe menu, select advanced wipe, tick the system, data, cache, and dalvik cache boxes, and swipe to wipe.
Boot back into the bootloader and flash the factory images (minus the userdata.img).
Boot the phone up.
If you need instructions for any of this look at my guide:

Bootlooping Nexus

My Nexus 6P is seemingly bootlooping.
I can boot into the bootloader menu but not into recovery. My bootloader is not unlocked so I cannot flash anything.
Issuing the command: "fastboot flashing unlock" does not work nor does "fastboot oem unlock". I cannot flash a custom recovery. Because my bootloader is locked.
Any help would be great.

You say that your bootloader was not unlocked, so I'm assuming you didn't have developer options turned on and USB debugging checked before fastboot flashing unlock?

Do you remember if you modded anything prior to bootloop? The reason you can't unlock bootloader is because USB debugging isn't on. What version of Android were you on when it happened? I believe you can still use google factory Image to restore your phone.

Since you don't have twrp you probably don't have a backup, which what I'm going to suggest will bring you back to stock and may lose everything. Though it's better than a bricked phone. Since I never did the flash-all.bat you may lose your stuff on internal SD. In this link, download the correct image your phone was on (under angler) and if using windows use the flash-all.bat in fastboot. If you're phone isn't 32 GB, extract all from zip and flash everything except user data. Forgive me for assuming you may be new. https://developers.google.com/android/nexus/images

Tried that. Continue to get the "Remote: (device is locked)" error every time it tries to flash a new image.
I'm not worried about losing any data on the phone. everything is backed up in the cloud.

Do you get the error on all that you try to flash? Maybe just try the recovery img only to see if you can at least get that. If that works you should be able to sideload ota through recovery. With having a locked bootloader you might be at a loss. But on the flip side, having everything locked and not rooted you should be ok for warranty replacement.

Fastboot is useless since your bootloader is locked. Try to ADB sideload the latest OTA image from Google and see if it will boot.

Tried running through those steps. I can't even get a temporary boot of TWRP or stock recovery continues to bootloop even though WugFresh claims it was successful. Tried doing it manually via Fastboot and continue to get the error in flashing.
I just received my replacement phone. So I might just call it a day on this one. :crying:

Good to hear about replacement! There are a few people in these forums that have a brick and can't get out of it. I thought you couldn't Hard brick these phones unless that was your goal. And most of these users who have bricks don't even know what causes it. Just a random reboot then loops. Kinda scary.

Bootloop With locked bootloader 7.0

My 6p is stuck in a bootloop. nbd90x build my bootloader is locked is there anyway to unlock from adb. I have already tried sideloading ndb90x through adb wipping chache and user data and still no luck. Help me Xda youre my only hope..

So you previously enabled USB debugging, how about OEM unlocking? If so, use 'fastboot flashing unlock' to unlock the bootloader. Note that internal storage will be completely wiped. Everything. Though with USB debugging enabled, you should be able to adb pull the contents of you SD card first. If you can unlock the bootloader you can try flashing factory images with fastboot. Otherwise, not much else besides RMA it with Google. There's been a few reports of stock N6Ps bootlooping. Haven't seen anyone post that Google denied the claim.

no bootloader is locked so cant flash using flashboot but debugging is enabled so I am able to use adb .

I know. What I'm asking is if you enabled allow OEM unlocking in developer settings? That doesn't unlock your bootloader in itself. You still need to use fastboot to do it. However if that setting IS enabled what you can do is... Use ADB to pull your internal storage to PC. Then use fastboot to unlock the bootloader and flash factory images. If the setting is not enabled, and wiping data and flashing an OTA don't work, I'm not sure what else can be done.
You can try downloading the 7.1 dev preview OTA and seeing if it updates whatever is causing it to fail. Other than those, RMA would be your best bet.
https://developer.android.com/preview/download.html#device-preview

After sideloading a ton of times between 7.0 and 7.1, one time i got it to boot up then i immediately enabled oem unlock then it crashed again... so now I am able to flash through fastboot although I havent been able to get it to boot again. Is it normal for bootloops to not get fixed by flashing?

Hijacking your post to report what is happening to me. I posted the same thing on the Android Beta program community on G+.
Have been using the latest beta since it came out on completely stock 6P (locked bootloader, unrooted). Everything working normally when yesterday around 10 or 11AM, phone starts to bootloop OUT OF NOWHERE, it was just sitting there on the table while I was working. I could still get to bootloader/recovery, so that was a bit of a relief. First thing I tried: clear cache, nothing. Then proceed to wipe/factory reset the device, to no avail. Immediately downloaded the latest factory image from Google's page, tried flashing it but couldn't since the bootloader was locked (OEM unlock option also disabled). Then downloaded the beta OTA and sideloaded it, process went through OK but device still bootloops. Tried sideloading the latest stable OTA but didn't work since it was from a previous build. Ran out of ideas. So there I was creating a thread on XDA for help while the device was still on its bootloop rush, about to hit the Submit button when again OUT OF THE BLUE SKY the device decides to boot itself back up. First thing I did was unlock the bootloader. Phone worked normally for 6 or 7 hours, when I'm doing something on it and then again, screen froze and bootloop starts again. This time I only reset the device and left the it bootlooping, after about 30 minutes it boots up again. I unenrolled from the beta and installed the latest 7.0 build. Everything working fine for the last 12 hours. Anyone have any idea on what can cause the device to bootloop like that? Never seen anything like it.

Yea I signed up for the beta program too do you have the link to unenroll? So you just reset and let it sit?

Here you go
google.com/android/beta

do you remember what you did to get it to boot?

Well, that's the thing. Everything I tried didn't seem to work. I couldn't flash the factory image since the bootloader was locked. I was able to sideload the beta OTA but the device still bootlooped after that. So I just left it bootlooping and after around 20 or 30 minutes the device booted normally. I have no idea what caused it and what I did to make it work again.
P.S: device restarted 2 times while I was typing this.

If your boot loader is locked you are screwed, sorry to say, I would RMA it. Unbelievable an update can mess a phone up...that's why I always unlock the bootloader first thing and never lock it. I need complete control of my phone.
Edit: Only thing I can think of is delete the partitions with fastboot or adb and reflash factory image.

boot loader is unlocked now Ive tried flashing using the flash-all script but the phone still wont boot

As a last resort, flash all of the images manually with fastboot. This will wipe all userdata and completely format the SDcard. Nothing will be left. Extract the bootloader and radio images from the factory images zip. Flash them in fastboot. Reboot to fastboot again. Extract the next zip in the same folder as BL & radio images and flash the vendor, system, boot, recovery & userdata image files. Just for good measure, boot to recovery (stock Android recovery) and perform a factory reset & cache wipe. If the phone still fails to boot, your only option would be to RMA it at this point.
Note: As per Heisenberg's sticky thread, do NOT flash userdata.img if you have anything besides the 32gb model as you will only have the ~32gb storage available. If you're using a model with more storage, just use fastboot to format userdata but don't flash the image.

Ill try that.. but isnt the warranty voided because the bootloader is unlocked?

Not on a Nexus, no.
Added: I had to RMA mine after the phone got its first update. I unlocked the bootloader and stayed stock for a long time (until N came out). I took the OTA in About Phone and it applied with no problems but the phone would not boot. Factory images also couldn't get it running. Stock recovery and all. RMA'd without issues. I didn't tell them, just sent it in. If they tried to boot it they would've seen the unlock symbol. There's also a thread somewhere buried in the general section where someone called Google and asked and they confirmed to them that unlocking does not void warranty. I'll try to find it for you.
Found it: http://forum.xda-developers.com/nexus-6p/general/unlocking-bootloader-warranty-google-t3229804/page1
I also returned 4 faulty Nexus 5's (mostly screen artifacts) all unlocked with no problems.
