You can't do it with adb. The only way is to use fastboot from the android sdk (same folder that adb is located in) and use:
Code:
fastboot flash zimage zImage (where the second zImage is the filename)

To flash a zImage:
1. Place the zImage you want to flash inside your AndroidSDK\tools folder
2. Reboot your phone into FASTBOOT/bootloader mode
3. Run the following commands (from your AndroidSDK\tools PATH):
Code:
fastboot devices -- Should pull up serial #
Code:
fastboot boot zImage -- Your phone will automatically reboot
The command above will only temporarily boot the new zImage, meaning you can test and do whatever you want, but after you reboot your phone again -- your previous zImage will be reloaded, removing the current one you were testing (Recommended method for testing, until you're sure you want to permanently flash).
If you want to make the new zImage you're trying to flash permanent, enter this command instead:
Code:
fastboot flash zimage zImage
Fastboot might hang so just turn the power off on your Evo then put it back into “fastboot” mode by pressing on the Power button WHILE holding down the Volume down button. Then press Power button once more to enter “fastboot” mode. You should see the image flashing now. Just reboot after that.

I'm trying to flash a zImage and I first got this error with the 0.97 bootloader
Code:
writing 'zImage'... FAILED (remote: not allowed)
And with the eng bootloader the error says
Code:
writing 'zImage'... FAILED (remote: unknown fail)
Anybody have any ideas to fix this? I searched for a while and turned up nothing.

do you have eng .76 bootloader? it is the one needed for clockworkmod. also, instead of the second zimage, type the name of your file. are you on a mac or a pc? if you are on a mac, you will need the mac fastboot file. pm me if you need it.

I flashed the eng bootloader and that's when I started getting the "remote: unknown fail" error when trying to flashe the zimage.
The file IS named zImage so that's right.
Plot thickens- now it will only boot into fastboot. I tried restoring my nandroid and it will still only boot into fastboot. I can get into the bootloader and recovery no problem but the phone reboots into fastboot every time.
I tried to flash a stock PC36IMG file and during the install process next to boot it says Fail-PU.
Now it says "Partition update fail!"
Please tell me I didn't just brick my phone.
EDIT: Ok, I flashed the PC36IMG file again and now it's booting again. My question is this- is the kernel stored on the boot partition? Would wiping the boot partiton and then flashing the zImage work? What commands would I use to do that?

I am a ubuntu user,
but you need root permissions,
Try what you get when you type : fastboot devices
When you get an error with no permissions. Get root acces (in ubuntu sudo -s)
try export the fastboot directory path and run fastboot devices again.
Then when that is working, try your thing again. There will be no errors

Hello, another post added to a year old thread.
I am getting trouble trying to flash a custom compiled HTC amaze x715e. (unbranded, S-off, unlocked, SuperCID)
I cross-compiled the kernel source and now have the zImage in my /arch/arm/boot folder.
fastboot flash zimage zImage
results in 'FAILED (remote: not allowed)'
fastboot boot zImage
results in 'FAILED (remote: reproduce boot image with on-flash ramdisk error)'
How am I suppose to flash this?
Is there a thread for this?
Thanks in advance.

HELP. HOX is dead

Hello
Yesterday i unlocked bootloader on htc one x. Then i tried to root it but when i finished my hox did reboot and then reboot all the time. It goes on start screen of android and then reboot again. I cant do anything. Any idea or help?

How did you root it?
Did you flash a ROM without flashing its boot.img and fastboot erase cache?
Did you install a custom recovery?
What screen are you stuck on? "htc quietly brilliant"?

I remember when this happened to me when I first tried to root my phone (First Android phone actually) lol I freaked out.. In my case it's because I didn't make a full wipe after unlocking bootloader and flashing Cyanogen, just booted into Recovery, full wipe/wipe cache and it worked.
Tell us what you did like BenPope said, did you flash the boot.img for the ROM you installed?

the first i did was to unlock bootloader from htcdev. Afther that i tried to root by a guide from this forum:
ALTERNATE ROOT METHOD - 'INSECURE BOOT AND ROOT'
This zip file contains an insecure boot image to flash to your device and a script which will then push the root (SuperSU) files to your device. This is only tested on 1.27.401.2 / 1.27.401.7. USE AT YOUR OWN RISK!
Download
InsecureBootAndRoot r3 - DOWNLOAD (ROMraid) - MD5: a16bff582cb0e25fd3b422652d753ca7
How to use InsecureBootAndRoot - Windows, Linux and OSX
- Download the InsecureBootAndRoot zip file above and extract to a directory
- Put your device in bootloader mode - Turn off the phone then turn on with the 'volume down' button pressed to enter the bootloader, then press the power button again to enter fastboot.
- WINDOWS - double click 'install-insecure-windows.bat'
- MAC - Open a terminal window to the directory containing the files, and type 'chmod +x install-insecure-mac.sh' followed by './install-insecure-mac.sh'
- LINUX - Open a terminal window to the directory containing the files, and type 'chmod +x install-insecure-linux.sh' followed by './install-insecure-linux.sh'
The device will now flash the new boot image and reboot. Keep the device attached to USB and when it has rebooted, ensure USB debugging is enabled - the SuperSU files will then be installed.
CONVENTIONAL ROOT METHOD - 'SUPERBOOT' (currently not functioning on shippping devices).
Superboot is a boot.img that when booted, will root your device the first time you boot (installing su and the superuser APK). No need to flash any partitions, no need to mess around with ADB, no messing with the contents of your data partition, no overwriting the shipped ROM on your device, just boot the boot image using the instructions below and you're done!
Download
Superboot r1 - DOWNLOAD (ROMraid) - MD5: c79821d5d75d57dff8a5ffe7493241fd
The superboot image is also 'insecure', allowing you to use 'adb remount' as well as having full ADB root access to your device until such time as you reboot after running this process (it's a non permanent ADB root as it's a 'fastboot boot' and not a 'fastboot flash' but it IS a permanent root in all other regards!).
How to use Superboot - Windows, Linux and OSX
- Download the Superboot zip file above and extract to a directory
- Put your device in bootloader mode - Turn off the phone then turn on with the 'volume down' button pressed to enter the bootloader, then press the power button again to enter fastboot.
- WINDOWS - double click 'install-superboot-windows.bat'
- MAC - Open a terminal window to the directory containing the files, and type 'chmod +x install-superboot-mac.sh' followed by './install-superboot-mac.sh'
- LINUX - Open a terminal window to the directory containing the files, and type 'chmod +x install-superboot-linux.sh' followed by './install-superboot-linux.sh'
That was the steps. I didnt tried to put a custom rom yet. And the worst is that i need my number and i dont have an another device with micro sd. :/

It's funny, because there are two methods that you've pasted there. I have to ask, why did you not go with the recommended one? The one you didn't paste here?
Try it, you might like it.

I tried the first one and after i saw that my hpox rr all the time i tried the second one.
You mean this method?
EASIEST ROOT METHOD - 'RECOVERY + SUPERSU'
The easiest way to get root is now to install the official ClockworkMod release and then flash the latest SuperSU zip file. This approach is highly recommended (I also recommend running a backup as soon as you've flashed clockworkmod!)
I do now and nothing. Cant get the command.

I don't understand what "my hpox rr all the time" means.
At the top of your hboot does it say ENDEAVORU or EVITA?
What does "can't get the command" mean?
Edit: ahh, is it "command not found" when you try to run fastboot?

You could just flash a rooted rom and kernel now, it should work fine.
Flash this recovery http://download.clockworkmod.com/recoveries/recovery-clockwork-touch-5.8.4.0-endeavoru.img
Install a rom from recovery, you can mount usb from recovery to copy rom to phone.
Then flash the kernel from fastboot that acompanies the rom.

ENDEAVORU is good.
I kind of expected you to be flashing clockworkmod 5.8.4.0 as the recovery.
Once that's done, you take a backup, download the SuperSU zip file, boot into recovery, mount sd as USB, copy the zip onto the SD card, unmount and flash it.

I dont know what you flashed, but you'd be better off with the latest clockworkmod, version 5.8.4.0
Doing a backup from that recovery is easy.

What I dont get is why you didn't just root/unlock bootloader via htcdev.com

The command you did was correct but you flashed the stock recovery, flash clockworkmod recovery to proceed.

I used that command fastboot flash recovery recovery-clockwork-touch-5.8.4.0-endeavoru.img
So i think i didnt something wrong.

I'm confused, earlier you said you flashed recovery-1-28.img
You're going to have to be clearer on what you write here.

Stuck in Fastboot/No Download Mode

Hey guys !
So since i messed up with the recovery mode, i'm stucked in the fastboot with no Download mode (recovery doesnt work neither).
So after searching 3 days in the internet i found the acces to fast through adb by puting a new laf.img in order to restore the download mode and flash a stock firmware !
My problem is that when i try to enter the command on the cmd, i get severals errors, take a look :
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>adb devices
adb server is out of date. killing...
* daemon started successfully *

C:\Program Files (x86)\Minimal ADB and Fastboot>adb shell

sending 'laf' (18432 KB)...
OKAY [ 0.581s]
writing 'laf'...
FAILED (remote: flash write failure)
finished. total time: 5.615s
Also command : "fastboot boot laf.img" result to "Failed(remote: dtb not found) instead of flash write failure..
Of course i have my G3 855 32GB in download mode (but it goes into fastmode), so when i try a command, lines are added in the screen etc..
Does that mean that my laf.img don't work? I assumed that so i try several, but does it have to be the exact same one as the one who was in my phone before( v20a if i record correctly ) or could it be from any 855 32GB version ?
I also thought it could be a recognition problem as when i type "adb devices" or "adb shell" nothing is found..
If someone has any clue or a link to some guide i'll be more than joyful, thanks in advance !

Hey thank you so much for answering !
What do you mean by that, i already download the adb/fastboot driver and launch a cmd in the directory they are at, writing "adb fastboot" has no result neither, can you be more specific please ?

cm13 recently messed up my phone in exactly the same way, no recovery and download mode would jump straght to fastboot. I followed this guide to the letter and am now back running again: http://open-freax.fr/guide-unbrick-your-lg-g3/

Well i hope my problem can be solved in a safer way, i dont like much to go on the hardware part, so I'll use it as my last hope, but thanks
Altought i think my device is recognized by fastboot in someway because it responds when i type commands in fastboot, and also when i reboot it.
But i'm getting this error :
Code:
error : command never completed
error : auto CMD12 error
error : command completed with errors
error : command timeout error
failed to send stop command
failed writing block @ 1
in the screen of my phone. Does that stand for Cyanogen mode which i was trying to put on my phone ?

I mean when you enter command in cmd use adb before any command also use cmd which one available on android sdk folder....also you can use this method if adb not workinhg properly http://forum.xda-developers.com/lg-g...-9008-t3072091

Oh ok ! Also your link is not working :s
I understand that the method can work but I think that the method i'm trying to use is really close to succeed, over my search on the internet, i saw lots of people who manage to succeed with it.
But i guess i must do something wrong. I downloaded the kdz file according to my IMEI.
Then I extracted the .dz file with LG Firmware Extract. Then I extracted the file named laf_393216.bin from the dz file. Changed his name into laf.img , put it into the fastboot directory.
Then i typed
Code:
fastboot format cache
fastboot erase laf
fastboot flash laf laf.img
in a cmd from the directory.
It all seemed to work, but then when i remove the battery and restart into download mode, it goes into fastboot after the download mode charging animation..
Also when i try to boot with fastboot boot laf.img i get the error (remote: dtb not found) on the cmd.
And ERROR: Unable to find suitable device tree for device(194/0x0001001/112/0) ERROR: getting device tree adress failed DTB offset is incorrect, kernel image does not have appended DTB)
Am I doing something wrong, should I changed more file than just laf ?

I don´t know what exactly is the problem, maybe something with your win-driver, some crashed or drifted partitions or some broken files...
I just can repeat my advice: I was in the same situation with my phone after a failed cm13 update and i was trying and reading about 2 days how to solve it - after the above mentioned method, your phone would get out of this "coma".
Maybe somebody else here in this forum could help you with your mentioned method, sorry.

Well I think i'm still under warranty, so i dont wanna touch to much on the hardware.
So do you think, if i send it back without touching anything, saying i put it on charge one night and the next morning it was like this, the warranty could work?

If they found it's rooted or they understand you did something with your software your warrenty is void ?

Remove the battery, put it, press the volume + and connect to PC USB, if like entering download, what happens to us not to go, will leave the ****ing LoGo, Well, hold down the volume + and not let go, I think it is less for 2 minutes more. After a while, the computer tells us that something was connected, the phone will tell you who is in fastboot as I said before, if not let me fastboot flash boot files and the LAF, recovery ect, nothing happens, there is still a magic command.

You have several options:
- find your phone firmware, extract recovery.img and flash it back through fastboot(do exactly the same for the LAF partition to restore download mode)
- flash a custom recovery for your phone model, if it doesn't work try an older version of TWRP, also it can be that your phone is not d855 but d850 model, so try to flash a d850 custom recovery and see if it works(that was exactly my problem and why i got stuck in fastboot mode, because my phone is d850 model and in settings it says d855, so I flashed wrong TWRP)

It seems that your phone's bootloader is locked, you can try to execute this command: "fastboot oem unlock", and then check state with "fastboot oem device-info". But some people says that it does nothing, so you can try and check for yourself.
You can also try to boot directly an image from fastboot for eaxmple:
Code:
fastboot boot laf.img
or
Code:
fastboot boot twrp.img
So if you could successfully boot a laf image you would be able to access download mode, and if you could boot a custom recowery then you could access ADB and to try to flash other partitions, or even flash a custom rom...

Yes i did this before, i was running on Remix OS

I don't know if this is of relevance but there were new fastboot commands introduced from Android M (?) and I have recollection about "partial unlock" - two flags required to be set and if only one was set it could be reported that the bootloader was unlocked but fastboot saw it as locked. Above may be totally wrong.
Here's the difference between old and current fastboot commands. Note the new lock/unlock commands
Code:
************************ OLD **************************************
commands:
update <filename> reflash device from update.zip
flashall flash boot, system, vendor and if found,
recovery

Hi, I'm just wondering if you were able to fix your tablet. I ran into the same problem as you here and am not able to find a solution to it.

Hi !!
Sorry for bad news, but i didn't found any solution since my Pixel C was bricked. Maybe there is a solution, but I dropped it before finding it.
I hope you find something to fix it !

@viii_xvi Are you using "Minimal ADB and Fastboot" as shown in the post you quoted by -Yazh- ? The current (?) version that I can find is 1.4.3 and that looks to be "2015".
For the current versions of adb and fastboot and the revision history, 12 since October 2016, see https://developer.android.com/studio/releases/platform-tools.html

No. I used the 15 second ADB and Fastboot installer. I'm pretty sure it works fine as I can use fastboot commands.

There are Youtube videos on installing Android Platform Tools and a web search for installing Android Platform Tools with your o/s will find many hits. You need to know you are installing just the platform tools - some of the guides assume you are installing or have installed the full Android Software Development Kit (SDK).
Assuming you are using Windows then the simplest method is to copy the contents of the zip file into the current location of your "15 second" files. This ensures that you can run the new version of fastboot with the folder path you have used previously. In file manager "find" fastboot.exe and that will give you the folder to unzip ALL of the platform tools files. You will know if you have done it correctly if you get requests to overwrite existing files when you unzip the files.

I've followed the instructions so I'm confident I did it correctly. Despite this, nothing has improved. I still can't flash the stock ROM or a custom recovery in fastboot.
What I've noticed from updating the fastboot version are some new commands I found when I entered "fastboot -h"
Code:
fastboot -h
commands:
reboot [bootloader|emergency]
stage <infile>
get_staged <outfile>
options:
--skip-secondary
--skip-reboot
--disable-verity
--disable-verification
--unbuffered
--version
From what I've tried, all the commands in options returns

Hi, Did you tried to flash with the oldest stock rom of the pixel C ? Because it uses older version of fastboot so maybe it will work. I has also the same problem as you but hopefully twrp still worked so i could flash another system image.

I have now tried to flash the earliest factory image and am disappointed to say the bootloader did not flash and so I wasn't able to complete the flashing.
I don't think the problem is the fastboot version. It may be the bootloader itself. I've read someone describe this problem as "Broken fastboot (bootloader) security." I think the problem is that, when unlocked, the bootloader would return the same messages as if it was locked. The security of the bootloader still thinks it's locked and not allow flashing of any images. Also that locking and reunlocking does not improve the situation. This would explain why, when bootloader is unlocked, I get "remote: unsupported command" and "remote: image verification failed", the same as when I try the same commands when the bootloader is locked.

I got a same problem,cant flash anything but ordinary using.
I got the problem caused by flashed twrp3.2.3,cant get into system,just always get into twrp.
cant flash any official firmware with "flash-all.bat",no matter which platform tool or firmware.but the twrp were installed before can flash anything.

I'm assuming you have the latest version of TWRP installed. IIRC, there should be "Fix Fastboot" in advanced options. If indeed you have the same problem I had, pressing this should fix the problem. I don't know anything beyond this as I never got to find out what happens afterwards.

I believe I'm not qualified to help you as I disposed of my tablet months ago. All the advice I've given is off of memory and may not be accurate. That being said, I won't help you anymore in fear of giving inaccurate information that may lead to bricking of your tablet.

I have a pixel C, flashed with latest 3-rd pixel experience before, someday i tried to flash back to factory image, hit the same trouble like this topic, i came here several times before, no solution, today, i found another article about this , it's solved my trouble.
sorry i am new here, i couldn't share the outside article link.
would like to share what i did on my pixel c.
1. root your pixel c
2. adb shell //this command could be executed under recovery mode too.
3. su
4. fwtool vbnv write dev_boot_fastboot_full_cap 1
5. adb reboot fastboot
then you could flash anything you want.

I had this just now - I finally got fed up of my Pixel C being so laggy and also chrome opening up as blank pages (I switched to brace to fix this, but it's abit crashy).
Anyhow I found that after
adb reboot bootloader
that
fastboot flash recovery twrp.img
was failing for me in the "Writing" stage
I discovered that the fix was to use
adb flashing unlock
then it will ask you a question (power button to confirm and one of teh volume keys to cancel).
after this it spins with erasing for a while and then comes back to fastboot after which
fastboot flash recovery twrp.img
Worked, after this you get an annoying 30s delay for each restart, I think that can be fixed by
adb flashing lock
I'll verify this when I've finished flashing a usable ROM to my Pixel C...

How to install twrp without being able to boot into system?

I hate doing this since I've been a long time user and usually am able to figure stuff out on my own, but I'm hoping there is an easy fix. I dirty flashed the new aokp update over an older aokp version for the pixel xl and i forgot to flash the twrp image after. Now the system ui crashes upon boot (no surprise there) and I can only get into bootloader and the stock phone recovery. How do I get twrp back?

You fastboot boot twrp then flash it in twrp. The same way you got it the first time.

This why I wouldn't use a toolkit, you're just kind of handicapping yourself..
You don't need adb to fastboot. either you are using adb (in the booted OS or in recovery) or you are using fastboot (in the bootloader).
You should take a gander at a few of the guides in the Guides section on how to install recovery.

If you are in bootloader mode when you type adb commands it will fail. You use Fastboot commands at that point.
ADB commands are for when tbe phone is booted normally.

Can you mount the system and use adb commands through the stock recovery? I can't seem to get any fastboot or adb commands to work at all. Even when the system is booted up. The system ui crashes, but shouldn't adb commands still work at that point?

Who knows what else crashed if the ui crashed. Power down, count to ten. Then power and vol down. Once in recovery, connect it to the computer. Not before.
Fastboot devices
If it shows flash the factory image. Modify the bat file and remove the -w to save your data.
If it doesn't connect try other usb ports. Mine won't connect to my front panel, only the rear.
And try another cable.

I am not a fan of TWRP backups on the Pixels. Seen a few bricks, especially on R2.

So i have attempted to fastboot flash a twrp img and its failing.

target reported max download size of 536870912 bytes

OKAY [ 0.917s]
writing 'recovery'...
(bootloader) Flashing active slot "_b"
FAILED (remote: partition [recovery] doesn't exist)
finished. total time: 1.020s
Am I safe to try a factory image or am I doing something wrong trying to flash the recovery image. ADB commands don't seem to work at this point for some reason.
Thanks for any help!

You are doing it wrong. You copy the TWRP zip to the phone.
Then
Fastboot BOOT twrp twrp-3.0.2-0-RC1-fastboot-marlin.img
That boots you to twrp. Then you install the twrp zip while in twrp.
You can not install twrp any other way.

Fastboot boot to twrp as I described. TWRP has ADB in it, so then from your computer you can ADB push the twrp zip and install it.
But I still advise you to flash the factory image after removing the -w from the flashall bat file.

He shouldn't bother removing the -w. A fresh image is what he is in need of. Wipe the phone and start over. Easy.
