I'm on Linux Mint 18.3 and my G620S-L01 phone is on Android 4.4.4
I have downloaded minimal adb and fastboot tool.
First question, when issueing "adb devices" and "fastboot devices" command, shouldn't I get the same output? ( which is from what I understand the device serial number ). This is what I get:
Code:
./adb devices
List of devices attached
84dbac441b79 device
./adb reboot-bootloader
./fastboot devices
no permissions (user in plugdev group; are your udev rules wrong?); see [developer.android.com/tools/device.html] fastboot
sudo ./fastboot devices
3a226eb fastboot
Then when I issue any oem commands I tried, I always get "FAILED (remote: 'unknown command')" like for example:
Code:
sudo ./fastboot oem device-info
FAILED (remote: 'Invalid command')
fastboot: error: Command failed
I have read in some other thread, that to make oem commands working "OEM unlock" needs to be set up in Developer options. But from what I understand, this option is for >= Android 5.something. How to make those commands working on 4.4.4 version?
Edit:
I have then downloaded and installed full-blown Android studio. But the result is the same.

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

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
Hello, I have been trying to successfully flash this phone since i purchased it a few months ago now, and I have been unsuccessful in being capable of doing so... Does anybody know what this means and how I may resolve it?
This is the output...
Code:
[[email protected] Recoveries]$ fastboot boot boot.img
Sending 'boot.img' (8498 KB) OKAY [ 0.430s]
Booting (bootloader) Command is not support
FAILED (remote: '')
fastboot: error: Command failed
Also sideload on trying to use adb also says that it is unsupported or something. Is it possible that this phone is impossible to do any such type of thing with such as flashing its ROM?
Thanks...
It is a Motorola Edge 20 Fusion...
And this is what happens when I actually try sideload...
Code:
[[email protected] rooting]$ adb sideload UPDATE-SuperSU-v2-82-20170528234214.zip
adb: sideload connection failed: closed
adb: trying pre-KitKat sideload method...
adb: pre-KitKat sideload connection failed: closed
Thanks...
1. You can't use Fastboot to boot into boot.img, but you can flash the boot.img:
Code:
fastboot flash boot boot.img
2. If ADB returns connection closed then try to force ADB to run in USB mode:
Code:
adb usb
.
I need the boot.img for the EU-Version. Can someone please help me? Thx in forward.
Here are both magisk patched and stock boot.img files
Using latest magisk 25.1 stable
Stock
Magisk Patched
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

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?

Did you pass the safetynet check?
My new Nord 2T is arrived today, I will see how many days it will resist unrooted

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.

this should unlock your bootloader
