Hello everybody,
I own a Lenovo k5 pro phone (L38041).
I've unlocked bootloader yesterday with this method, then I flashed via twrp zui 11 with android pie, prerequisite to install havoc 2.9. That overwrited twrp with stock recovery, so I tried to flash twrp again via fastboot but it got stuck sending.
See here, when prompted «FAILED (Status read failed (No such device))» is because I reboot phone bootloader after a long wait sending.
Code:
$ adb version
Android Debug Bridge version 1.0.41
Version 29.0.4-1

$ fastboot --version
fastboot version 29.0.4-1

Bootloader info:

SN: 4488d6fc
Device state: unlocked
In develorper options it shows as unlocked too.
Last thing, I've pushed some files via adb while system is on, (debugging mode on).
Thank you.
Today I've updated adb and fastboot to 29.0.4-2 with same result.
Some other commands I've tried (notice it fails when I restart fastboot at device some time after wait):
Code:
$ fastboot devices
4488d6fc fastboot
$ fastboot boot recovery-TWRP-3.2.3-0225-LENOVO_K5PRO-CN-wzsx150.img

fastboot: error: Command failed
$ fastboot oem unlock
FAILED (remote: 'unknown command')
fastboot: error: Command failed
$ fastboot oem lock
FAILED (remote: 'unknown command')
fastboot: error: Command failed
Any help?
I'ts solved.
I've used different computer and different cable, it was as easy.
Hi Guys!
So I got a phone from a friend to assist him with a problem.
When I opening the phone, the phone showing an error message "The system has been destroyed".
I tried to use Fastboot but when I running any command an error message received, for example:
Example1:
fastboot flash recovery "twrp-3.3.0-0-beryllium (1).img"
Sending 'recovery' (31068 KB) FAILED (Write to device failed (Invalid argument))
fastboot: error: Command failed
Example2:
fastboot devices -l
???????????? fastboot
Example 3:
fastboot flashing unlock
FAILED (Write to device failed (Unknown error))
fastboot: error: Command failed
fastboot oem device-info -v
< waiting for any device >
FAILED (Write to device failed (Too many links))
fastboot: error: Command failed
Any ideas??
Please help!
Thanks!

Obviously fastboot driver not installed on PC

When I try to use the Unlock Tool by Xiaomi, it just tells me "Request parameter error". I've tried multiple other methods thru adb, they all dont work for me. Can anyone help me here?
Tried "fastboot oem unlock" which resulted in this
FAILED (remote: Token Verify Failed, Reboot the device
)
finished. total time: 0.011s
then tried "fastboot oem unlock_critical" which resulted in
FAILED (remote: Token Verify Failed, Reboot the device
)
finished. total time: 0.013s

Hello, I've been struggling with this for hours and nothing seems to be working.
I have a Motorola DROID RAZR XT912 running Android 4.1.2 JB, it's already rooted but I'm attempting to unlock the bootloader using this guide.
I've installed the Android SDK as well as the latest USB Drivers.
I enter my mobile device into "AP Fastboot Flash Mode (S)" by holding power + volume down.
I plug my device into my laptop, the phone says "USB Connected".
I open a terminal in Windows 11 in my SDK tools directory [C:\Users\FOS11\AppData\Local\Android\Sdk\platform-tools]
I use the command "fastboot devices" to test if fastboot is working and detecting my device.
It properly returns with "014FFB290D006013 fastboot"
I attempt to use the command "fastboot oem get_unlock_data"
It returns with an error:
"FAILED (remote: 'unsupported command')
fastboot: error: Command failed"
I have followed the guide exactly up to this point with no errors, I have not found any forum or guide saying anything about this error, I must be missing something very simple, right? please let me know if any additional information is needed.
some moto/lenovo do not require unlock code. such old device maybe isn't even locked. just curious what happen for?
Code:
fastboot flashing get_unlock_ability
fastboot flashing unlock
fastboot oem unlock
fastboot getvar all
could be also possible it's non-unlockable bootloader (not intended by manufacturer, unofficial methods might exist)
"Your device is NOT eligible for bootloader unlock if the CID value returned is one of these: 0x0001, 0x0002, 0x0004, 0x0005, 0x0006, 0x0008, 0x000A, 0x000F, 0x0010, 0x0011"

probably means this bootloader cannot unlocked.
But last cmd shouldn't fail.. try special mfastboot.exe or more recent platform-tools
Code:
fastboot getvar unlocked
fastboot getvar securestate
fastboot getvar sku
fastboot getvar cid
or just try if unlocked by doing something invasive (does not harm on cache)
Code:
fastboot oem fb_mode_set
fastboot format cache
fastboot oem fb_mode_clear
