Nexus 5x "no command" & adb "error 21" - Nexus 5X Q&A, Help & Troubleshooting

Last night I did the update through OTG to my Nexus 5x but to restart something went wrong, after boot is shown to me a black screen instructions with an android.
"imgur.com/a/T3FXn"
Pressing the power + volume up key I managed to get into the recovery mode and I tried to flash Android 7.1.1 with adb but soon after I get an error:
"imgur.com/a/lADCT"
Probably an error connected to adb over to Android, but do not know how to proceed. The image of Android has been taken from here "developers.google.com/android/images?hl=en" , while adb is updated to version 1.0.36.
If something is not clear I apologize but my English is bad

Ok the solution to my problem was pretty stupid. I used to load TWRP fastboot and have them installed the latest version available for my device.

[Q] Stuck in bootloop (pls move if I'm repeating a tousand other similar Q's!)

Hi there,
I've been a bit of a [email protected] and fudged my Huawei P6. I Was on South African Vodacom Stock Jelly Bean Rom, read this forum and got so excited about the world out there that i thought, why don't i try flashing a rom, i've only bricked a sgs2 and lg-g2 before... I should know what to do by now (never done a day's computer course in my life!)!
So flashed kitkat beta and then tried to flash Kit Kat... I have left the phone for about a week in the hopes I'd come back to it & it would miraculously work as I've read a lot of the forum posts on here and have a gut feeling I'm screwed so hoping one of you Huawei P6 XDA Guru's can Help. From what I remember I did this...
1) Rooted the phone with SRS Root or Root Genius
2) After a few attemps managed to install official kitkat beta from dload/update.app from external SD Card so I could then install official Chinese KiTKAT rom or HYDRO Rom.
3) Played with the kitkat beta for a while all working (bar the beta crashes etc) ( I think at that point I intalled CWMOD or TWRP)
4) It was very late, I should have gone to bed, I'd had a few beers, but no I carried on & was planning to install Hydrorom & (Mis)understood got mixed up with official chinese kit kat rom installation
5) Booted into recovery & flashed official chinense kitkat rom with GAAPS ticked to flash as well (maybe that will tell you guys if I was using CWM or TWRP!)
5.0117...c) If my memory serves me right I didn't (4am idiot/tired/few beers/rushing etc) wipe dalvic or any of that... just flashed from external sd card ZIP streight over kitkat beta (aaaarrgh!)
6) Phone is now stuck in bootloop with Huawei Ascend words first, then loading a Huawei flower logo. Goes no further, just stays on until battery flat...
7) Left phone plugged into power with screen on for a day hoping it was just taking a while to flash rom... & nothing happened
8) Tried the following but hope I'm doing them all wrong and you GURU's will have a giggle at my comlete lack of skills:
a) reboot phone - no luck​b) hold down power & +vol & -vol -... no luck just flower logo again​c) every combination of power and two volume buttons - no luck just flower logo​d) putting folder dload/update.app on external sd card and using b)method to flash update - no luck just flower logo​e) putting stock recovery.img on root of external sd card and doing b) - no luck just flower logo​f) putting all of extracted TWRP download " TWRP_Installer_20140414 on root folder of external sd card - no luck​g) spending 4 hours finding a "how to remove the battery from huawei P6" link and watched a russian guy remove battery on you tube. Did that as read that can reset boot loader/recovery.... no luck​h) downloaded various versions of Android SDK Tools. Phone shows up as a "please insert sd card" in windows file manager and appears "offline" when trying to access it from command prompt ADB etc​
checked that HiSuite was stopped in Task Manager etc, reinstalled drivers etc. One problem I'm hoping you'll all say is 100% to blame for SDK Tools not working is I'm on latest update of Windows 8.1 64bit...
Edit: Read other forum... I see the red led when turning phone on as well...
Edit: Just installed propper android sdk tools not small made up file and now phone changed from showing "offline" to "unauthorised" in adb...
So, please help.
Fixed it
Ok managed to fix this and hope it will help others. Was up till 2am last night after deciding to give it another go after getting no replies! The main problem here must have been that as device was seen as unrecognized on PC and I couldn't get past boot screen so there was no way to allow debugging/authorize I.e. No pop up on phone as stuck in Hauwei flower screen.
Previously I Couldn't get fastboot or adb on PC to do anything, just kept saying phone was offline or unauthorized.
Rebooted phone from boot loop screen of huawei flower on screen holding power and - vol button for a long time until only boots to huawei ascend words logo (phone still plugged into PC), let go of both. PC makes sound to show there is USB device, now it doesn't boot the huawei flower screen just stays on the Hauwei ascend screen (I think normally this would open recovery etc), so maybe it is in recovery just not showing on screen... I don't know?!
Adb devices says no device however... And obviously no adb commands work at all...
However, fastboot commands for some reason work even though devices still shows nothing... so I tried various commands but what worked for me was typing the following in command promt on PC:
Fastboot flash boot boot.img (Stock)
Where all the img,zip,app files I was flashing were were in the platform-tools folder where adb and fastboot are.
Then
Fastboot flash recovery recovery.img. (Stock)
Then I think what did it, I was obviously on a broken twrp recovery... Was I flashed
Fastboot flash recovery twrp_2_6_3_3_recovery.img
To my amazement twrp touch recovery loaded and I could then go about wiping dalvik etc and reflashing all the correct files.
So I'm now finally running HYDROROM_V7
All the files I used are on the hydro rom page here so thanks to them for that! :

Hope this works for all of you stuck in bootloop etc as I really thought my phone was stuffed!

Hey very good that you managed to fix your problem, when I first read your question I didn't had any ideas on how to fix it. But you had a bootloop I think and when you press power and vol- until it reboots you come in the bootloader, on our device it only shows the bootlogo so its seems that it is stuck but actually you are in the boot loader and can use fastboot commands. So glad you fixed your problem.

LG G3 Hard Break

Hi there,
I have a problem that my LG will not boot the device is stuck at the logo, I've also done a hardware reset but the process also depends on the logo proof and 10min not happened.
In the download mode, I'm not coming.
About the fastboot mode I try to start TWRP, but it appears the TWRP logo and nothing else happens.
How did you manage to get it to this point? What did you do before it didn't boot anymore?
Also, if you manage to get adb access somehow you can just reflash the recovery again
I ran a SuperSU update and then he appeared dialog that I should restart the system and since I have the problem.
How can I flash the recovery again?
If I want to flash TWRP on the fastboot mode, only the TWRP logo and then nothing happens appears.
So you cant enter download mode or recovery? And you cant turn on phone?
No download mode is not only possible fastboot mode. If I we want to install Recovery in fastboot mode, shown below
Command: fastboot flash recovery recovery .img
Error on LG G3:
Error: Command never completed
Error: Auto CM012 error
Error: Command completed with errors
Error: Command timeout error

Something does not compute in this at all. SuperSU should not have caused your phone to brick like that.
Is there something else you are not telling us about how your phone was set up? Were you doing anything before you updated SuperSU? This looks like a case of where you flashed the wrong image on your phone, if you ask me.
SuperSU is not phone specific, so I'm having a hard time believing SuperSU did this.
Something else must have happened that you are not telling us. You need to lay out in order, everything you did to your phone up to the point of updating SuperSU.
Also, SuperSU asks how to update: normal or via recovery. Which way did you choose? Either one shouldn't matter, but it's a start.
I had the ROM KNVIRUS V11, since I got the message that an update to SuperSU are available. The update I installed then I get the message that the device must be restarted for the update to be finished and since I have the problem.
I wanted to start the download mode just in fastboot mode, unfortunately without success.

Did you flash the correct laf.img file for your model of phone? If not, that could be part of it. What model of the G3 are you using and where exactly did you obtain the laf.img file from?
SuperSU update should I install because the PlayStore has shown that there is an update.
laf.img I downloaded here: http://forum.xda-developers.com/showthread.php?t=2766437
I found a thread has to ängliches problem: http://forum.xda-developers.com/lg-g3/general/guide-how-to-restore-download-mode-t2897257

Well, there you go. I have NO idea for what version of the G3 that thread was for. The guy never states which version it is. You do not, repeat, do NOT flash anything to system, boot, etc for this phone unless you know for sure it's for YOUR model of the G3. There are various models of the G3. For example, mine is the Verizon model (VZ985). There is an AT&T model (DS855), and numerous others, especially for those overseas. I would not and should not flash the DS855 boot image to my VS985 boot image. It will brick the phone as you have found out the hard way from what I can tell.
You just flashed something you have NO idea which version it was for. You may have completely bricked your phone. I'm not entirely sure, but you need to find the correct stock images for your phone and flash them back.
You need to go here and figure out which model of G3 you have:
http://forum.xda-developers.com/showthread.php?t=2791269
After that, you need to go and find the correct stock image files and flash those back onto your phone. Since this are NOT img files, you cannot fastboot flash them. You muse use either KDZ or TOT files depending on which ones are available for your model of phone:
http://lg-firmware-rom.com/
or
http://storagecow.eu/index.php?dir=Xda/LG+G3/Stock/
Then, you have to use the correct tool to flash these files depending on if they are KDZ or TOT file:
http://forum.xda-developers.com/showthread.php?t=2785089
Hopefully, flashing back to the correct stock image will fix you up. However, you better make darned sure which model of phone you have BEFORE you even attempt it. Once you figure out which model of G3 you have, post here and ask. Otherwise, you could bork your phone up even worse to where it may not be recoverable. Hopefully, it's not at that state right now.
I have LG G3 16GB EU version.
As I have written on the first page, I get nothing into download mode so I can not flash it.
What I can not understand why no command in fastboot mode works no matter what I type, I always get the error message: FAILED (remote: flash write failure)

Again, did you verify with the link you posted for the image file that it was indeed for YOUR model of your phone? If not, you probably have bricked it.
You need to go and follow the links I posted which tell you how to flash back to stock.
There was no reason to go into fastboot mode for SuperSU. I don't know why you felt you had to do that.
Also, the second link you posted has the thread pretty much deleted. The OP said he was incorrect in what he posted (whatever it was I don't know since he deleted it), so it was removed due to it not working as stated.
Go back to the links I posted to flash back to stock on your model. If what you say you have is the European model, then this would be the KDZ file you want:
http://storagecow.eu/Xda/LG G3/Stock/Europe Common 16G D85510A_00.kdz
I would verify for sure that is what your phone is before continuing or else, you'll bork your phone up even worse than it is already.
The boot image you flashed is probably for the Korean version of the phone and that's why everything is messed up.
If you are not sure on how to do this, then you might want to find someone near you who does.
Just remember, just because a post says it's for the G3 doesn't mean it's specifically for YOUR model of the G3. You need to verify for sure that it is. Most have the model number in the thread's title.
LG G3 Fastboot

But now i am stuck again on fastboot mode and this time i was not rooted and did not had twrp installed so now when i try to use the "fastboot boot twrp.img " my device will reboot and then will be stuck on twrp logo on the screen
I have the same problem...
I ran stock OTA update 20f, since a couple of weeks ago. While I had my phone on the table and it was runing voice recorder soft it restarted once and then after a couple of minutes again. This time it never booted but stuck at the LG screen.
Never rooted, never installed anything other than the OTA 20e and 20f updates. I have not flashed anything to the phone other than the official OTA.
Doesn't boot to anything other than fastboot. Recovery starts but after confirming twice it reboots and stuck still.
If I boot to Download Mode it goes to fastboot, if I wait long enough on regular boot that only shows the LG logo it will eventually go to fastboot.
Running "fastboot.exe boot openrecovery-twrp-2.8.4.0-d855.img" gives me the same error messages, stuck at the TWRP logo screen. I found the ADB port is connected but when running "adb devices" it says "LGD855..... offline". I didn't enable ADB before the device crashed and I can't enable it in TWRP because it doesn't start properly.
I have the 32GB D855 European unlocked. I belive this is hardware problem and will send it for repairs.

Oeps, `flash write failure` brings back memory`s of the emmc failure with Samsung devices where the sdcard is no longer readable and can not be written on. Send it in for repair, there is no other way and they`ll probably replace the motherboard.

That's right. I tested to boot Philz recovery and it freezes at the text.
Mine says actually:
Error: Command never completed
Error: Auto CMD12 error
Error: Command never completed
Error: Command timeout error
Failed to send stop command
Failed reading block @ 1
mmc read failure misc 2048
The CMD12 is according to emmc spec a "Stop command".
So this is a hardware fault and not a software one.

Nexus 7 2013 - completely BRICKED

So I completely bricked my tablet, cant even get my PC to recognize the tablet, and the only screen i have up is the Google and the unlock padlock. and if i try a hard reset, all i get is android on his back and the red triangle. I have decided to buy a used motherboard, I see from ifixit.com that they are easy to repair, will this solve my dilema? I found used mobo's on ebay, made sure to get the correct one, is this the answer to not buying a new tablet?
My nexus 7 lte is in the exact same state(that's why I've posted here instead of starting new thread)...by using nrt to try updating to marshmellow as per site's instructions...wondering if anyone can offer a solution???
(bought at google play almost 2 years ago and they already sent me a free refurb replacement...but I still wanna try getting the old one going before sending it back if possible...worth a try before buying a replacement mobo)
here some details of my situation:
ran this on my nexus 7 2013 lte...failed on the first try...tried again..it wiped everything and then failed on install...now I have bootloader (accessible by volume down and power button simultaneously) only and no functional recovery(get the android with red triangle and asterisk when I select Recovery)...the only Android device listed in Device manager is Android Bootloader Interface.
If I start from fastboot mode:
gives a driver failed to load error from windows" and also, now in Device Manager my Android Device Listed changed from "Android Bootloader Interface" to "Android Composite ADB Interface", as well, there is now a Portable Device listed also but it's the driver that failed to load I guess "MTP USB Device" with a yellow asterisk.
If I run the flash-all.bat in the image download that the NRT got on the first attempt, everything goes fine until I get to "sending system"...this fails with unknown data transfer error...
when I download the latest image from developers google.com and extract it I get just one big file with no extension...shouldn't there be a bunch of files including a flashhall.bat file?
^Yes, inside the main image zip is the bootloader (+ radio in your case) and another zip of the actual partition images.
Run fastboot devices from the bootloader just to be sure it's detected. If not uninstall all traces from your pc and start fresh.
Flash the new bootloader, reboot bootloader, flash the radio, reboot bootloader then flash each .img individually with fastboot. Don't use any toolkits.
You should get the "OKAY" after flashing each image. Is it only system that fails? Do you get the okay with boot and recovery? If system only I don't know.

The android with the red triangle with exclamation is what happens with stock recovery, you need to press power, volume up and down quickly all at the same time to get in. Usually takes a few tries. If you can get into recovery you could factory reset. It could be another problem though. You have to describe what you previously did to it if you really wan't help.
rma
Thanks for the reply...was never able to get the system image to load...google play is supposed to reemburse me once they receive my original nexus 7 (already got a pristine refurb from them..updated to marshmellow..will be staying away from NRT with this one...)
Thanks again for the reply and suggestions!
system image can't be written
Exactly the same happened to me. After a successful update to MM with Wugfresh's NRT 2.0.5 (with no root) I tried to root my device with 2.0.6 which was released in the meantime.
But that failed because NRT thinks my bootloader is locked, while in fastboot mode I can see that it is unlocked. With fastboot commands I can relock and re-unlock but for NRT it makes no difference.
It seemed to me that a manual reflash of bootloader (FLO-04.05), kernel, cache, system and data should solve this, but no way. The flashall. bat reports a write error of the system.img. A direct fastboot flash system system.img command leads to FAILED (remote: unknown chunk type).
I couldn't find any information about chunk types. I am afraid that somewhere in the process the partitioning was affected. Is that a possibility and can anything be done to fix this? Or are there other solutions for the chunk type error?

Nexus 7 WiFI 2013 (Razor, FLO) CyanogenMod Recovery only...

I have a nexus 7 WIFI 2013 (Razor, Flo):
I was trying to get a copy of Nethunter or Kali linux installed on here. I was running CyanogenMod nightly's
Well during one install, I must of wiped the whole tablet clean. It only had dad/media and then subs /0, /obb folders. I'm unable to find any images on the card and nothing else is displayed. I have tried number numerous drivers for my Samsung laptop but when i use my surface it shows nexus 7 and also when i go into bootloader mode it will also show the driver.
I installed droid SDK and also minimal adb and fast boot. I'm unable to push anything to this device. When i run adb devices it shows the device but says unauthorized. I try adb kill-server and adb start-server and still no dice.
I'm looking for any input as to how I can push and image onto this device. I realize I will have to go back to factory and I have all them images. I just cant get it adb authorized yet.
this will only go into recovery mode and boot loader mode. There is no OS if I let it boot it just shows the mod logo and will sit there until the battery dies.
Does anyone have any input on how to get this authorized so I can push files to it. I'm unable to get on the screen and ok the RSA fingerprint and I think that maybe part of my hold up or why it shows unauthorized.
Thanks in advance for all or any input or ideas.
Start TWRP and it will authorize you to push any files anywhere.
I'm unable to get TWRP on this tablet. The main issue is I only have cyodgen mod recovery on the tablet. It will not boot. It will only go into recovery mode/bootloader mode. I'm unable to verify any RSA fingerprints which is causing me an issue getting the tablet authorized for ADB pushes. Does anyone know a way I can get it authorized via ADB without being able to access anything other then recovery mode? I think the RSA fingerprint is whats actually causing me an issue.

No need to flash TWRP - just start it directly from RAM:
download twrp-3.0.2-0-flo.img to your folder with fastboot and adb apps
boot the Nexus in fastboot mode (when off press power+vol.dn), connect it to your PC
on PC run: fastboot boot twrp-3.0.2-0-flo.img
when TWRP is up, ADB-push your files, no RSA concerns

I've run into the issue by running the Factory reset from the Settings on my Nexus 5x and ran into this bootloop, is there a way to get this fixed if I didn't have USB debugging on? As I was just plain Factory reseting my phone.

You not need usb debugging enabled in system.
Communication with pc is working in fastboot and recovery.

any idea how to do it in mac?
What do you mean with: "Copy downloaded OTA ROM archive in ADB folder."
Just sideloading doesn't work.
ADB cant find my 5x...
Thank you OP for this i am need of help and it appears your solution has found me. Im on holiday atm and my nexus 5x just got the dreaded bootloop! Alll i see is the spinning colors for android logo after pin code is inputted.
Im very anxious to backup my photos of my son and family, so want to ask is this method safe? I dont want to risk losing data.. i can get into recovery mode and my phone is boot locked and not rooted, so can someone also tell me if adb backup will allow me to backup my pictures and video reliably? I will do a full backup and then try and flash the OTA.
serving: 'bullhead.zip' (~47%) * failed to read command: No error , what im doing wrong ?
ok succeed after dozen attempts , phone booted to main desktop work for like 5 mins and then frozen , looks like it went back to bootlooping ;(
Hi guys, same situation, since yesterday I could boot with a bit of effort (like waiting 15 minutes of bootloop) but now the 5x doesn't boot at all and so neither in recovery. My phone is locked and never modded so I will send in warranty when I will be back home ( 10 days). So now I would like to fix it to use it at least in this week, but how can I do if I can't boot in recovery?
I can just boot in the bootloader so use fastboot command...if I unlock the bootloader I will get the little lock in the bottom part of the screen, when I will lock it to send it to LG will it disappear?
How exactly is this toolkit's fastboot flashing supposed to work if you have a locked bootloader?
How is using this toolkit any different from running the "flash-all.bat" that's included with factory images?
This did nothing at least in my case.
I get the feeling that the flash operations are failing and the toolkit just disregards this.
Cannot enter recovery
I completed the first step in fastboot but when i try to enter recovery it goes to bootloop again....what should i do?
Nope, not working. Rebooting again and again. Issue not resolved. Please help!
Hi I need help,
what do i choose when i click 'system' tab?

Hi,
I'm having the same problem.
Cannot enter recovery since the device just stays in bootloop, and I get the same message error if I try to sideload.
What were you doing wrong and how did you fixed it?
Tks

It's been a while since I tried it. But as far as I remember it was due to phone not being in recovery mode. I hold the power button until the phone screen went off. And while holding the power button I instantly pressed volume down button to bring back the fastboot mode and then recovery mode.
i'm sorry but i don't see my latest build (currently running on 7.1.2)
i've tried using 'any build', it said that i have to choose one of the build listed :/
thank you

edit
found them!
but it says that my OTA is out ouf date
I downloaded the latest one though (August)
where did I go wrong? :/
Anyone still doing this ha? I've just run into this issue with my wife's phone, and there are things on there she needs..
The ones with issue with the big cores causing bootloops, use this guide to unlock device then proceed with following guide

Hello, I've done all the procedure until reboot recovery, but I've didn't find the button for select apply update from adb in NRT.
