I'm using windows 10 64 bit and I have problem with fastboot, since it is the only thing i can access.
Anyway, when i type in "fastboot devices" it gives mi bunch of question marks.
Also none of fastboot commands seems to work, every one gives me " (command write failed (Unknown error)) "

Hi!
I have a problem with my Huawei Honor 6 phone.
I’m using ADB to reboot my phone to bootloader using "adb reboot-bootloader" and once in bootloader-mode it says “PHONE Unlocked”.
But when I try to run any command it fails. For example:
Code:
[B]fastboot oem device-info[/B]
...
FAILED (remote: Command not allowed)
finished. total time: 0.003s
I discovered this error because I tried to flash a recovery from latest beta stock that is Android Lollipop but got the error:
Code:
writing ‘recovery'...
FAILED (remote: flash write failure)
I did the same with the “boot” partition and it worked… But it won’t work with the recovery partition.
Current recovery is TWRP and right now I’m unable to get into recovery mode (the phone freezes).
I’ve read that these errors indicate that the eMMC chip is broken, but I would like to know if there is something I can try to fix this if it’s a software problem (partition table?)?
My model is H60-L02 bought from Singapore
I wanna bump this as its still an issue.
I'm unable to enter receovery and would like to know what people think, is it a hardware error?
I was following a guide on unlocking the idol 3. After sending it into fastboot, attempting to run "fastboot -i 0x1bbb oem unlock" returns an error saying "FAILED (remote: unknown command)"
Any idea why this might be happening or how I can fix it? I'm doing this on an iMac running the commands with ./ in the android studio "platform-tools" directory.
you'll need windows for restore adb commands

I'm trying to fix my phone via ADB/Fastboot, the phone is in fastboot mode because of a boot issue. Anyways, when I use fastboot I see that the commands are going to the phone screen and being processed but when I type "fastboot devices" it shows a serial number of 0123456789ABCDEF. I thought it would of shown my phone's serial number, is this correct? And is this also the reason when I try to use "fastboot erase recovery" or anyother partition it tells me-
erasing 'recovery' ...
FAILED <remote: failed to erase partition>
finsihed. total time: 0.015s
Any help would be appreciated!
Anyone know why?

Yeah idid i solved the problem , to use fastboot command with realme devices you should use an usb 2.0 port not a 3.0 or usb ones coz my laptops had only usb 3.2 i used another one and i succeeded now im on pixel experience, thanks for your time dude
Hey, I have an alcatel 3 and I wanna see how I can root it. I'm trying to root it using magisk but fastboot keeps returning the error unknown command all the time.
when I do
fastboot flash ...
it sends the file but then writing produces an error.
I know that I can root it and that I've done it before using magisk. but now it doesn't work. btw i don't think i fully unrooted my device so that may be the issue.
Fastboot deals with phone's bootloader where it doesn't matter whether phone's Android got rooted or not.
If you get shown
FAILED (remote: 'unknown cmd.')
fastboot: error: Command failed
or
FAILED (remote: 'Not implemet.')
fastboot: error: Command failed
means the bootloader wasn't unlocked properly.
Try this command sequence
Code:
fastboot devices
fastboot flashing unlock
fastboot flashing unlock_critical
What if
fastboot flashing unlock.
Returns command not found
If "command not found" is returned by Fastboot when trying to unlock bootloader then unlocking phone's bootloader is denied.
what if i have to run sudo to use fastboot could that be the problem
Fastboot deals with Android device's bootloader: So it's irrelevant whether Android is rooted or not.
Take note that Fastboot isn't Fastboot hence not all Fastboot commands do necessarily work as expected: it depends on how OEM implements Fastboot.
having the same problem with my qlink tablet but when using command fastboot flashing unlock
it returned fastboot oem operation fail: unknown cmd' : error: command failed This is my first time rooting anything help please?
hellp me ty pls!
Have you turned on "allow OEM to be unlocked" in developers option
