[Q] Unable to use fastboot - Huawei Ascend P7

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
...
(bootloader) unlocked

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...
Code:

Any other hint?
Thanks in advance!

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?
Debugging is enabled...

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 .

fastboot error lg optimus l90 D415

So I have an LG D415 and I don't know if it's bricked, softbricked, hardbricked or whatever, i'm really a noob and would really appreciate some help, I've included a picture, that shows what pops up when I try entering "Download mode" but I've already tried flashing the KDZ files, I've tried factory resetting the phone, nothing seems to work, phone always shows 0% battery even after charging for over an hour, and so I tried getting into the fastboot commands and stuff, I extracted the laf dz from the kdz files, renamed it to laf.img, put it in the same folder as my fastboot drivers (not even sure if I have the correct drivers) I open up command prompt inside the folder, type in "Fastboot flash laf laf.img" and the following appears in cmd:
target reported max download size of 536870912 bytes
sending 'laf' (13312 KB)...
OKAY [ 0.586s]
writing 'laf'...
FAILED (remote: unknown command)

I feel like I am missing something or missing some steps, I've got the laf partition, the fastboot drivers(I think) phones in fastboot mode even though at the top it says download mode, no idea as to what to do or try next, if anybody could help it would be very much appreciated...

What ROM are you using? I think you should try flashing the bootstack with recovery from here >> https://forum.xda-developers.com/lg-l90/development/bootstack-kk-l-l90-t3118632. When you flash the bootstack, recovery gets rewritten with an old version of twrp so you probably want to have an IMG of twrp to update to the latest version.

I'm not aware of what ROM the phone is using, and I don't even know if the bootloader is unlocked, or if the phone has TWRP or root, and I don't want to mess the phone up even more (if that's even possible) phone was a friends and he gave it to me, said I could keep it if I could fix it, and i don't currently have a working phone, so it would be really nice to fix this one, i'm really a noob when it comes to this stuff, but I'm willing to learn if that's what it takes to fix the phone, I also included a link that shows a picture of the information that appears when i type in "fastboot getvar all" in command, not sure if that could help you

So the first to do is run the command fastboot oem unlock with the phone connected to your computer with fastboot. Then download the latest twrp from https://dl.twrp.me/w7/twrp-3.1.1-0-w7.img and flash it with fastboot flash recovery twrp-3.1.1-0-w7.img making sure that you move the twrp IMG to the directory where fastboot is unless fastboot is on your path where you can just flash it from cmd in the downloads folder. After that, try to factory reset the phone and it should boot into twrp where I would flash the lollipop bootstack linked above with adb sideload "zip name here" where you put the full filename of the zip in zip name here and remove the quotes, boot into the download mode thing which is fastboot and reflash recovery with the instructions above.

How can I flash TWRP?
I've got a TWRP file named "TWRP_2.8.0.0_26.09.14_L90.img"
Tell me where to go from there, and also, the phone isn't even detected using the command "adb devices" it says list of devices and does'nt ever show anything...

Flash twrp by first moving the twrp IMG to where fastboot is and running fastboot flash recovery TWRP_2.8.0.0_26.09.14_L90.img with the phone in the download mode thing and connected to the computer.
Also, could you please re-run fastboot getvar all even if you have already run it because its output probably changed and send me an image of what it shows.

After that, run fastboot reboot recovery to reboot into recovery. Press the advanced button and then press the button that says adb sideload with the touchscreen and start it. Then to install the zip run adb sideload zipname where zipname is the name of the zip you want to flash.
After that boot back into the download mode thing to reflash recovery and then reboot into recovery with fastboot reboot recovery. After that I would flash the zips for a ROM and optionally gapps with adb sideload.
This is what I get:

Try with USB 2.0

(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 :

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

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.

Unlocking Bootloader Issue

Hello guys!
I have an XT1929-4 on android pie and I am having issues with unlocking my bootloader.
I am using the fastboot unlock method and I am always getting stuck with the "fastboot oem get_unlock_data" command. "fastboot devices" shows my device serial number. OEM unlock and USB debugging is also turned on in the devices settings. The tool I am using is the minimal ADB and Fastboot software. Tools mode config is enabled when I do the fastboot commands, If 'fastboot oem help' should work, then maybe all 'fastboot oem' commands are not working for me.
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot devices
ZY2268BV45 fastboot
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem get_unlock_data

^I did the fastboot oem get_unlock data twice here.
I was planning to flash pixelexperience rom when I saw the thread here. Thank you in advance and I hope somebody can help.
FIXED: i used all three usb A ports of my laptop. I tried using the usb c port of the laptop by using a usb c to usb a adapter. fastboot oem get_unlock_data worked.

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

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
