Huawei Nexus 6P :: Can't Relock Bootloader - Unknown Command
Nov 3, 2015
I noticed there were 2 newer images on the Google developers page and thought I would flash the latest and greatest (MDB08M) since it wasn't coming down OTA. I enabled Developer Options and set USB debugging and OEM unlock, rebooted to bootloader, did a fastboot oem unlock, rebooted then back to bootloader and ran the flash-all.bat from the new image, rebooted and all was well. I re-enabled USB debugging and went back to bootloader to re-lock the bootloader and am getting an error:
...
FAILED (remote: unknown command)
finished. total time: 0.016s
Results of fastboot getvar version-main are blank:
version-main:
finished. total time: -0.000s
I rolled back to MDB08K but it made no difference. I then tried rolling back to MDA89D and letting it pull MDB08K OTA but that too made no difference.

I'm not an Android rooting noob (my rooting goes back to OG Moto Droid in late 2009) and I'm sure it's something ridiculously simple I'm missing but I can't get my bootloader to unlock. I've tried ADB/Fastboot, WUG's Nexus Root Toolkit, and Chevy's Android Job Box. Nothing works.
I got my 6P today, SIM'ed it up, booted up, logged in, enabled USB debugging, installed the drivers, and let it update. When I opened WUG's NRT, I saw that I had an Android build one step later than the NRT. Mine's MD80BL and K is the latest in the NRT. I thought that shouldn't be a problem and selected the "any build" option with the Nexus 6P. I went through the installing drivers process and can access the file structure of the phone through W10.
I then went to the unlock bootloader option, clicked through the prompts until the phone rebooted into the bootloader and clicked the OK button to unlock the bootloader. About two seconds later a window popped up on my desktop telling me my bootloader was unlocked, my data was wiped, and I would have to go through the setup process on the phone. Excellent, except my phone booted right back to my stock homepage. I tried again with the same result.
I then tried it manually using ADB/Fastboot. The "fastboot devices" showed a connected device which I assume is my 6P since I have nothing else Android connected. When I type in "fastboot flashing unlock" I get all the fastboot commands/options as if I typed an unknown command. "Fastboot oem unlock" didn't work either. I went and downloaded the latest SDK and retried everything with the same result.

I came from getting my nexus 6P and I wanted to install twrp and etc... So I went to into developer mode, I check USB debugging and enable OEM unlock.
I head to my computer open a commend prompt that's has the fastboot and adb drivers. I connected my nexus 6p and I enter the following commends
Adb reboot bootloader
Fastboot devices
(Showed me my devices)
Fastboot OEM unlock
And just after I hit that I got the following
...
Failed ( remote : commend not found)

Yesterday i got notification with new update that i have to setup, so after charging my phone at night i started the update this morning then boom I can't start my nexus anymore...
First I got message ( your device is corrupted. it can't be trusted and may not work properly ) although i didn't make any custom rom nor recovery nor unlock my boot loader
Second I got No command error , then boot loop all the way .....
After some google i tried to press power + volume up and down to enter recovery ( the stock recovery ). I did wipe cash + wipe data factory hoping it solve the problem but seems no way
Also i read Heisenberg's How-To Guide For Beginners many times and downloaded last Stock img but can't install it via fastboot cause i didn't activate usb debugging before nor “Enable OEM Unlock” so i can't even unlock my nexus.
Recovery version :
angler
6.0.1
MMB29P
And this is getvar all :
(bootloader) version:0.01
(bootloader) unlocked:no
(bootloader) hardware-revision:ANGLER-VN2
(bootloader) version-baseband:angler-02.50
(bootloader) version-bootloader:angler-02.45
(bootloader) display-panel:
[Code] ....

Ok, so I just got my awesome new 6P. Here's what I've got so far:
I have the SDK, ADB and Fastboot components installed, drivers listed, and everything like I've been reading here and other forums.
So far I've been able to verify that ADB and Fastboot both seem to see my device OK so I know the drivers are good.
USB debugging mode is enabled in the Developer menu, and the option for 'allow oem unlocking' is enabled as well.
From what I'm seeing this all adds up to 'should work', but it isn't.
I originally tried the 'fastboot oem unlock' command found in older posts, and when that didn't work found (from what I'm able to determine) the latest command of 'fastboot flashing unlock'. Unfortunately, all this gets me is this: [URL] ..... (wont let me just link the image since I just had to make a new account. Been too long since I last logged in apparently ...

So I think I know the answer but wanted to validate. If I leave the bootloader locked on my device and download a factory image from Google, cannot I just put the zip on the sdcard storage and run it through recovery to update? I don't think that I need to unlock the bootloader do I? I am trying to keep everything stock for now, but updates are a big reason I wanted this phone. Also don't want to break Android Pay.

Is there a way to remove the warning on boot, after the bootloader has been unlocked.

I haven't received mine yet, but probably one of the first things to do is unlock the bootloader. Does the fingerprint verification/ unlock still works with an unlocked bootloader.

I am already unlocked and rooted, but I would like to relock the bootloader assuming that I can unlock it for future updates without losing data. The Nexus 5 had a boot locker app in the App Store which allowed this, but I do not find an option for the 6 P.

Do you think it may be possible that we can get root access without unlocking the bootloader - I'm a little reluctant to unlock the bootloader because of the QFuse blowing.

Last year I bought the nexus 6 and for the first time (I've had a lot of android phones) in my phone was also disabled force encryption after the bootloader unlock, twrp and root. So I decided to decrypt it because reading on the nexus 6 forum some devs suggested this to increase the phone performances.
I read that now twrp supports encryption and that Google increased the phone performance also with force encryption enabled.

Is it possible to unlock bootloader, root, flash twrp and somehow flash the stock rom? If yes, where can I get the rom files for flashing with twrp?

The Volume Down button is jammed (the phone fell and landed on its edge slightly crushing the frame where the volume down is). Curiously the Volume Up button still increased the volume.
After turning the phone off the problem came when turning on the phone as it now only boots into the bootloader as a result of the jammed Volume Down button. Once in bootloader mode, the volume up/down buttons do not change the reboot options - it appears the stuck Volume Down button is causing this.
The way to fix this is to take the phone apart (as per the Youtube clips) and physically straighten the frame. This is no easy task, so the question: is there a way around this so that the phone can boot?It's rooted and fastboot commands work. (I installed TWRP but can only boot to recovery with adb).

Running LMY48M. I am trying to enter recovery mode to wipe cache and all I get is the stupid robot on his back saying no command. I have tried volume up and power button no menu comes up... Phone is starting to have some quirks and figured I would try wiping cache before anything else.

I went into recovery and rebooted, still get the "no command" screen. Factory reset didn't fix it either.
I got into fastboot and ran the flash-all from an image I got from Google and got "'fastboot' is not recognized as an internal or external command, operable program or batch file."

I have a nexus 5 that I was preparing to hand down to my wife. I had transfered everything over to my new phone, and initiated a factory reset. It rebooted to the "erasing" screen, and sat there for about 20 minutes, before switching to the dead android screen (w/ red triangle.) I thought that was odd, did some searching, and tried the recovery mode from the bootloader. That produced the same results. So now I'm stuck.
From the boot loader I can access the following options:
Start -> Erases for ~20 minutes, then dead android
Restart Bootloader -> Screen goes blank, phone vibrates, and then back to the bootloader screen
Recovery Mode -> Erases for ~20 minutes, then dead android
Power off -> turns off the phone
I called Google, and the tech support hadn't heard of anything like this. Because it's almost two years old, he transferred me to LG's tech support, who basically said find a local repair shop, or they could RMA it for an unknown cost.I'm pretty sure the phone is bricked at this point, which is frustrating, because it was running stock android - completely unmodified. I think I might have rooted it once, months ago, but I can't imagine that that would have caused this issue. I had even received and installed Marshmallow OTA, and it was running perfectly.
Anyway, some program I might be able to use on the PC to regain access to my device.
Literally the only information I can provide about the phone at this point in time is as follows:
Product_Name - hammerhead
Variant - hammerhead D820(H) 32GB
HW Version - rev_11
Bootloader Version - HHZ12k
Baseband Version - H8974A-2.0.50.2.27
Carrier Info - None
Serial Number - 047....
Signing - Production
Sercure Boot - Enabled
Lock State - Unlocked

I was trying to install a ROM and things got a bit messed up. I wiped system/cache/dalvik/data via TWRP. I then went to install the ROM but it failed due to only supporting hhz12h bootloader.
So now I'm kind of stuck. I can't update the bootloader because fastboot/ADB won't list the device in TWRP. Is there any way to launch an ADB server in TWRP so I can fastboot the bootloader? Doesn't look like there is.
If there's not: Is there a TWRP zip-install hhz12h bootloader I can use? Looked around, couldn't find one.
If not I'll have to try and find/flash the original image..but fastboot is not going to happen so I have to find a zip installable one that'll work with hhz12d bootloader...which hopefully is around. Otherwise I could install literally anything just to get an ADB server so I can fastboot the hhz12h bootloader in there.

so I was trying to flash the latest Nexus build to my Nexus 6, but the bootloader was taking 10+ mins to flash, so I tried closing out of cmd and then restarting my phone into bootloader. Unfortunately, now, my computer doesn't recognize my phone, saying that the drivers are no bueno, so that when i type fastboot devices nothing shows up.

my Nexus 5 has recently run into a problem where it suddenly decided to get stuck in a bootloop. I figured I could just reflash the stock rom via the boot loader with the wugfresh root toolkit but that unfortunately didn't work. But by doing this I noticed that my bootloader was not staying unlocked when I try to unlock it. Every time I unlock the boot loader and it restarts the bootloader automatically re-locks. I then proceeded to try and manually flashing the stock rom files individually and unlocking the bootloader each time I flash a file which was really annoying. It still hasn't worked and I'm starting to get worried because I've also started to notice my recovery can't really factory reset or wipe the cache. Instead I get this message at the bottom of the screen:
E:failed to mount /cache (Invalid argument)
E:Can't mount /ache/recovery/log
E:Can't open /ache/recovery/log
E:failed to mount /cache (Invalid argument)
E:Can't mount /ache/recovery/last_log
E:Can't open /ache/recovery/last_log
E:failed to mount /cache (Invalid argument)
E:Can't mount /ache/recovery/last_install
E:Can't open /ache/recovery/last_install
E:failed to mount /cache (Invalid argument)
So now I'm completely stumped, could this be the end of my Nexus 5?

1) voice recognition so that device unlocks itself in order to perform the given task using voice command is mandatory.
2) Saying ok google should work even with the screen off.
3) Ok google to type and send in an another app....
4) changing the command "ok google" to some user defined command.
