getting FAILED (remote: unknown command) after using fastboot boot <recovery_filename>.img
Fixed it with msmdownloadtool

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'm trying to install TWRP and ROOT my device. I have a TMO GM1915 that i converted to international firmware following the guide, my bootloader is unlocked, USB debugging enabled, one plus drivers and adb/fastboot binaries. When I try to boot TWRP using command "fastboot boot TWRP.img" it fails. I get this:
D:\Kevin\platform-tools> fastboot boot twrp.img
downloading 'boot.img'...
OKAY [ 1.031s]
booting...
FAILED (remote: unknown command)
finished. total time: 1.031s
I read in a different thread if that happens to type this command "fastboot set_active b" and try to boot again, and if that fails to type command "fastboot set_active a" and try again. When I type either of those the commands they aren't recognized by fastboot. If anyone can help i would appreciate it.
My device is GM1915 OS 9.5.13.GM21AA
Hello there,
I just got a Nokia 6.2 to use for my app reverse-engineering/development needs, but I would need to root it.
Recovery is just saying "no command" and fastboot does not want to flash recovery.
Code:
C:\Users\<user>\Downloads\platform-tools_r29.0.5-windows\platform-tools>fastboot flash recovery twrp-3.3.1-PL2.img
Sending 'recovery' (38736 KB) FAILED (remote: 'unknown command')
fastboot: error: Command failed
Apperently the device's flashing functionality appears to be encrypted.
per the how-to at https://www.androidweblog.com/nokia-6-2-ta-1198-root-install-twrp-recovery/:
Code:
C:\Users\<username>\Downloads\platform-tools_r29.0.5-windows\platform-tools>fastboot oem unlock-go
FAILED (remote: 'Failed to unlock, decrypt failed!')
fastboot: error: Command failed
Device state is listed as unlocked.
Try
HTML:
fastboot flashing unlock
i wnat to root https://www.xda-developers.com/root/
when i try
D:\platform-tools>fastboot flash boot D:\platform-tools/magisk_patched-25100_1VYTU.img

Code:
Sending 'boot' (98304 KB) FAILED (remote: 'Download is not allowed on locked devices')
fastboot: error: Command failed

Rename the patched boot.img to "boot.img", then place the patched .img in your fastboot folder on PC then type:
fastboot flash boot boot.img
When you place the file in your fastboot folder, you don't need to include the path to the file in the command, it automatically looks for the file in the fastboot folder by default when you do not enter a path. Renaming the file to "boot.img" isn't necessarily required, but, it does simplify things for fastboot and makes the command easier to remember and type.
The same applies if you want to flash a system.img, recovery.img, etc.. Just change the name of the file to "system.img" or "recovery.img" and place it/them in your fastboot folder and it simplifies your commands to:
fastboot flash system system.img
And
fastboot flash recovery recovery.img

You've to unlock device's bootloader. Hence 1st of all if you want to manage the / operate on the bootloader you have to move device into fastboot mode and then run on device if it's launched 2015 or later
Code:
fastboot flashing unlock
[code]
instead of the outdated
[code]
fastboot oem-unlock

The platform tools you actually use are meant to be used with Google devices only.
Use the Android USB-tools provided by your device's manufacturer.

I'm having simular issue with my specter 8 tablet. I unlock the bootloader and give me the normal prompt. I go back do everything else and will execute reboot devices ect. However won't flash patch_boot.img brings up message

I need the boot.img for the EU-Version. Can someone please help me? Thx in forward.

Thank you. I've now read rooting is not possible because Mediatek. Is it true please? Will not break it.
I'm rooted on my Nord2T. Whoever said that does not know what they are talking about.
The original Nord 2 was also mediatek and has a few custom ROMs and everything
I'm not able to boot correct in bootloader. There is written at the display extreme small "Fastboot Mode". If I set command "fastboot oem unlock" there is no reaction and nothing written. Changing with up/down is nothing doing.
Pushing Vol- and Powerbutton ends in recovery. There it is only possible to choose language and then wipe, reboot and power off.
My firmware is: CPH2399_11_A.09
Wrong code not
Code:
fastboot oem unlock
The correct command is
Code:
fastboot flashing unlock
Sorry, can not unlock the bootloader
Both commands failed
PS C:\adb2> fastboot flashing unlock
FAILED (remote: 'Unrecognized command flashing unlock')
fastboot: error: Command failed
PS C:\adb2> fastboot oem unlock
FAILED (remote: 'Unable to open fastboot HAL')
fastboot: error: Command failed
PS C:\adb2>
Try using a different ADB and fastboot. I use official platform tools from here
Also what comes up when you type
Code:
fastboot devices
Have downloaded and used the tools from official platform (your link)
PS C:\adb3> fastboot devices
UKGYBYZTL7699T8T fastboot
PS C:\adb3> fastboot flashing unlock
FAILED (remote: 'Unrecognized command flashing unlock')
fastboot: error: Command failed
PS C:\adb3> fastboot oem unlock
FAILED (remote: 'Unable to open fastboot HAL')
fastboot: error: Command failed
I'm in "Fastbootd Mode".
The command was "adb reboot fastboot". The command "adb reboot bootloader" does not work at mine N2t

Did you enable developer options and select Enable OEM unlock first?

Don't rush and don't do it like me. Here boot images are for 09. So upgrade first.
Safety net passes with magisk module
Root easily hidden with lsposed and shamiko module.
