[Q] Unable to use fastboot

After installing B126 in my rooted P7 I'm unable to use fastboot although the phone shows unlocked bootloader in the screen.
Code:
$ sudo adb reboot bootloader
$ sudo fastboot devices
???????????? fastboot
The device seems unrecognised and when I try to flash or boot anything I get the following error:
Code:
FAILED (remote: Command not allowed)
On the other hand I'm able to reboot via fastboot command.
I'm using linux and running fastboot and adb as root in order to ensure I have permissions to access to de device although this shouldn't be necesary.
Why could this be happening?
Thanks in advance.

I've been trying other things with no success.
I've installed windows on a VM and rebooted the phone into fastboot mode. When I try to list devices in fastboot I get the '?' answer as if the phone wasn't recognised.
Device drivers seem to be installed as no missing drivers appear in the device manager.
How can I fix this?
Thanks in advance!
UPDATE: Added some more info
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot.exe oem get-bootinfo

Did you make the
Code:
/etc/udev/rules.d/51-android.rules
file? It is necessary to create it with the correct information to make ADB work on Linux.
If you don't have the file, read this: http://askubuntu.com/questions/213874/how-to-configure-adb-access-for-android-devices
The first answer explains how to create the file. You don't need to be root to use ADB by the way.

Thank you very much for your time and patience!
AFAIK changing udev rules only lets you use the USB devices with your regular user avoiding the need of elevated permissions. Anyway, because I had nothing to loose I've tryed the solution you adviced. Here are the results...
After creting the udev rules for my user I no longer need to use the sudo command for getting results with adb or fastboot, which was expected, but I keep getting the "Command not allowed" with fastboot.
Code:
$ fastboot oem ?

On the other hand, fastboot devices now returns something interesting...

Any other hint?

Well, the bootloader seems to be fine and the fastboot ID "0123456789ABCDEF" seems to be also OK (according to this thread it means "the device is in fastboot mode"). My guess is a permission problem - is the device rooted? Also, this thread's resolution for this error message was turning debugging mode on - so you might want to check that too

My device is in B609 not rooted because the method used still not very convincing to me... Could it be this?

If think yes, it might be. It surely looks like a permission problem, and since you are not rooted, it could be that those commands can't be used.
Rooting B609 was pretty hard for me - I flashed the bootloader of B608, then used CWM to flash SU, and then I was 100 percent rooted. If you don't want to root your phone, I'll try tomorrow (or later today - it's 0:50 here and see if fastboot commands work properly when rooted. What commands should I try?

Is this also happening to you?
I would like to be able to use fastboot boot for some kernel testing... It seems there's source code for kernel building both from Huawei and the comunity and it would be nice to have a free kernel as a base for cm devel...
It is also 00:50 here (Spain)... Tomorrow will be another day, no hurry

1. After editing udev rules, fastboot recognizes your device correctly ('fastboot devices' returns your device's SN).
2. Presence of su doesn't affect on work of fastboot anyhow.
3. You can't use 'fastboot boot' command because it's not supported. Huawei's bootloader supports very limited set of commands.

Thank you Kostyan_nsk! I really appreciate you sharing your knowledge .
About 2 I thought the same but I was not sure... so why not trying...
About 3 do you know what are the supported commands or where to find that information? It would be nice to have a post in the developers section with some documentation for those who want to perform tests with the device .

[Q] Nexus 6 - Unlocking OEM from bootloader is possible?

Hi All,
I know I have messed up, but want to know is there any remote possible way to do this?
I tried to flash and it failed and on top of that I used

Try this: Reboot to bootloader, select recovery mode, enter TWRP, mount MTP and push/sideload and flash a flashable image from here http://forum.xda-developers.com/nexus-6/development/fxz-nexus-6-recovery-flashable-fastboot-t3066052.

TWRP cannot flash the stock images. Only flash able zips. The modified zips linked by @gee2012 should work

(solved) Can't either unlock OEM or install recovery (Preflash validation failed)

Hello
I just purchased a cheap new Moto G7 Plus, only to install LineageOS on it. The phone is brand new and I just upgraded it to the latest Android 10.
I followed all instructions so far, and I am stuck, can't unlock the bootloader and/or install a recovery.
To unlock the bootloader I carefully followed instructions on the LineageOS wiki
Then I followed instructions on Motorola website
I received an email from Motorola with the unlock code
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem unlock CODE_RECEIVED_IN_THE_MAIL
...
(bootloader) Check 'OEM unlocking' in Android Settings > Developer
(bootloader) Options
OKAY [ -0.000s]
finished. total time: 0.016s
Despite the fact that it says OKAY, when I reboot in fastboot flash mode, I still see the message "oem_locked". So I am not totally sure that the unlock succeeded.
Then whatever I try, I can't install TWRP, see below :
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot devices
Z*****F5RR fastboot
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem unlock CODE_RECEIVED_IN_THE_MAIL

FAILED (remote failure)
finished. total time: 0.702s
C:\Program Files (x86)\Minimal ADB and Fastboot>
I obviously googled a few time but can't find any working solution. Some says its because my OEM is still locked, others because the USB port or cable might be problematic. I tried on 5 USB ports and a USB hub and I have the same issue, and my cable is brand new. I also restarted the whole unlocking procedure, received another mail from Motorola, with exactly the same unlock key, unlocked 10 times, nothing changes.
Any hint ?
Cheers

Ok forget it, its solved. I am an idiot I forgot to activate developer mode in the settings

trying on my xt1965-2 and having this same issue, did you manage a workaround?

The twrp file needs to be in the correct location and the name needs to be exact.
I use linux so check up on which locations to use in windows.
But on linux I open a terminal in the folder where twrp is located.
So if the filename for twrp is for instance "twrp-3.3.1-0-lake.img", the command needs to be:
fastboot boot twrp-3.3.1-0-lake.img (NO spaces in the file name!)
Fastboot then pushes the file to the phone and boots it.

[HELP] Unlock bootloader without OEM Unlock (Phone doesn't start)

¡ I need help please !
I have a HTC Desire 10 pro (From Aliexpress, yes warranty avoid), it was working fine (more than a year) until a few days ago. One morning I took it and it was off but the notification led was not on despite charging. I tried to turn it on and enter to recovery but it was not responding. I decided to open the phone to remove the battery and verify that it was not damaged. Mysteriously the battery was in good condition, and once I removed it and plugged it back in, the phone responded again when connecting the USB and the charger.
But there is a problem, when the system is going to boot, after showing the HTC logo, the phone turns off together with the notification led and returns to the state in which I found it at first.
I removed and placed the battery again so that it would respond again, but now I entered to recovery to make a reset, but the problem is that the recovery is very outdated, so it does not have the "wipe data" options.
It should be said that i can enter into a "recovery mode" that shows:
"

Where the blue txt is the actual menu.
In this "recovery mode" I can't use ADB commands, i only can execute some fastboot commands (PC recognizes my device because of fastboot drivers) as "reboot", but for example:
* I can't use the "erase" command because my current recovery is not supported:

* Nor I can directly install the TWRP recovery because it tells me:

Well, this is the situation, and i think the solution is:
install the TWRP recovery to do a factory reset and if necessary install a ROM (official or not).
Buuut, to install the recovery I need to activate USB debugging (MANUALLY in the android options) and activate the OEM unlock option to unlock the bootloader, which is impossible for me since the phone "turns off" before starting.
My question is:
How to activate OEM unlock option without having to access to android settings? I mean, with commands in fastboot or in some software.
I have searched a LOT on the internet and I can't find anything about it, all the tutorials have the device fully functional, not like me that my device does not start.

Finally "getvar all" command shows this (i think could be useful):

Well, this is the situation, and i think the solution is:
install the TWRP recovery to do a factory reset and if necessary install a ROM (official or not).
Buuut, to install the recovery I need to activate USB debugging (MANUALLY in the android options) and activate the OEM unlock option to unlock the bootloader, which is impossible for me since the phone "turns off" before starting.
My question is:
How to activate OEM unlock option without having to access to android settings? I mean, with commands in fastboot or in some software.
I have searched a LOT on the internet and I can't find anything about it, all the tutorials have the device fully functional, not like me that my device does not start.

Wow. With a little more time another user (HTC U11+) enters the queue of the mishaps! Any Luck anyone? HTCDev also seem to have given up with no option to login to their website.

Question NE2217 Can't unlock my bootloader

I got my token, hit oem unlocking. Rebooted to fastbootd mode, then I use fastboot flash cust-unlock. Which returns,
C:\Users\James>fastboot flash cust-unlock C:\Users\James\Desktop\10pro\unlock_code.bin
Sending 'cust-unlock' (0 KB) FAILED (remote: 'Download is not allowed on locked devices')
fastboot: error: Command failed
If I try it without cust-unlock I get,
C:\Users\James>fastboot flash C:\Users\James\Desktop\10pro\unlock_code.bin
unknown partition 'C:\Users\James\Desktop\10pro\unlock_code.bin'
fastboot: error: cannot determine image filename for 'C:\Users\James\Desktop\10pro\unlock_code.bin'
If I fastboot reboot to bootloader and do the same command I get,
C:\Users\James>fastboot flash cust-unlock C:\Users\James\Desktop\10pro\unlock_code.bin
Sending 'cust-unlock' (0 KB) OKAY [ 0.002s]
Writing 'cust-unlock' (bootloader) Device is unlocked.
OKAY [ 0.004s]
Finished. Total time: 0.099s
But, that doesn't actually unlock my bootloader. Can someone please help?

Here's some more I have tried
C:\Users\James>fastboot flashing unlock
FAILED (remote: 'Unrecognized command flashing unlock')
fastboot: error: Command failed
C:\Users\James>fastboot flashing unlock C:\Users\James\Desktop\10pro\unlock_code.bin
fastboot: usage: unknown 'flashing' command unlock
C:\Users\James>fastboot unlock C:\Users\James\Desktop\10pro\unlock_code.bin
fastboot: usage: unknown command unlock

Edit:
Sequence of commands
Code:
fastboot flash cust-unlock unlock.bin
fastboot flashing unlock

I even renamed the file but here's what I got,
C:\Users\James>fastboot flash cust-unlock C:\Users\James\Desktop\10pro\unlock.bin
Sending 'cust-unlock' (0 KB) FAILED (remote: 'Download is not allowed on locked devices')
fastboot: error: Command failed
C:\Users\James>fastboot flashing unlock
FAILED (remote: 'Unrecognized command flashing unlock')
fastboot: error: Command failed
Then I moved the unlock.bin and same results.
I was able to hit oem unlock so it shouldn't be sim related, but thanks for helping

Four things:
Name of file doesn't matter
SIM unlock and bootloader unlock are separate things
Move the unlock.bin to the same folder as your platform tools so you don't have to put the entire the path. Or put it in quotation marks
Is fastboot in your system PATH? If not, prefix fastboot to look like this
Code:
./fastboot.exe

Also, what does the following command return?
Code:
fastboot devices

C:\>fastboot devices
*serial number* fastboot
Also not too sure what you mean, "Is fastboot in your system PATH? If not, prefix fastboot to look like this"
But it is installed to my system drive. Even tried downloading new platform tools and trying it in my root drive of C:\

No worries. If you got the "5497b039" returned it means fastboot is working for you and your device is in the correct bootloader mode.
Does your device display "locked" in red letters?
Are you sure that "OEM unlock" is still toggled in the developer settings?

Okay so I got it, thank you for the help.
Did the commands you sent in the bootloader menu, guess I missed the second.
For anyone who can't unlock the bootloader I'll post simple instructions, on the NE2217
OEM unlock - on
adb reboot bootloader
fastboot devices
fastboot flash cust-unlock unlock.bin
fastboot flashing unlock
anyone can add anything else
