Unlocking and flashing a recovery under linux

Hey,
I need help unlocking the bootloader under linux, since I can't "find" my phone while in fastboot, and can't use
Code:
fastboot oem get_identifier_token
because that ends in
Code:
< waiting for device >
What I did:
- Shut down the phone
- Rebooted into the bootloader
- chose "fastboot"
- connected to my laptop (USB 2.0, original cable)
- started ADB
- used the commands up there
- waited, and waited, and waited
--> nothing happens.
Where did I go wrong?
Cheers! :good:
Edit: Before I forget: USB debugging is on, fastboot is off

Did you use sudo or su? By default adb and fastboot require su pernission
Sent from my HTC One_M8 using xda app-developers app

Adb won't work for bootloader unlocking. You need fastboot
sent from my mobile device

I forgot to use sudo before fastboot oem get_identifier_token.
All good now.
With my Nexus 10 I never needed sudo for fastboot. Well, on the other hand, unlocking was way easier.
Thank you!
PS: Quick Question: Is there an ETA for CWM? I prefer it over TWRP or PHILZ, just because I'm lazy.

Fastboot doesn't see Nexus 5 X, ADB and filetransfer work fine

Hi guys,
i recently received my nexus 5x and would like to root it like my old nexus 5.
The drivers are installed, filetransfer from and to phone/pc is working, adb see's the device. PC is windows 7.
But when my 5x is in fastboot mode the fastboot devices command shows no results and any other command like fastboot oem unlock get stuck at < waiting for device >.
Am i missing something? Do you have any idea?
Thanks for your help!
edit: the device manager shows the 5x as unknown device when in fastboot mode

Download the latest version of fastboot.exe

Yep, I was having fastboot issues as well but it turns out that there are updated fastboot binaries for Android 6.0 that you need to get.

fastboot never start after update to android 6

Hy
I had an unlocked bootloader phone. Yesterday I flashed the new Android 6, Europe version from the Huawei blog forum, no beta, on my Huawei GX8. I used the method, dload on SD card, Phone off an the press Volume down+volume up+Power button.The flashing was normaly.
Now the phone starts normaly but I can´t start fastboot. When the phone is off and i press Vol down + Power the phone start the android system and the Huawei logo is coming not the fastboot Modus. I can see my phone and the order under Windows but i can not control my phone with the fastboot command. (example: fastboot device. the answere ist searching devices, but it comes no resolution) I loaded the last version of Fastboot, but the problem is the same.
Please can you help me. What can i do? Many thanks for your help!

And when you use adb to reboot to bootloader, what happen? Do you have "Minimal adb and fastboot tool" installed?

Sorry for my question, what´s the differents about adb and fastboot tool? I have install the last version of minimal adb and the fastboot tool, also the Windows driver for the phone. Debugging is on. I try to connect my phone about the fastboot terminal. When i try to set the phone into the bootloader mod with the fastboot terminal and the equivalent command, fastboot say´s "searching phone". My phone does not react.

So, you connect your phone, open minimal adb and fastboot too, run "adb devices", you see device id? If yes, run "adb reboot bootloader" . Phone shoult reboot to fastboot mode. Then run "fastboot devices" to see if it is connected properely.

i did it, like you described, but i see not my device id. Only the note "seach device"
Is it possible that TWRP is defect on my device? Is TWRP necessary for fastboot or only for root?

No, you should be able to use adb and fastboot with stock recovery.
After first adb command you shoult approve authorization on your phone.

Here is screenshot from minimal adb...
Phone must be in MTP mode.

And here is phone in fastboot

Many thanks for your help, now I m in my bootloader.
2 problems i had.
1. My daemon was not started correctly, i have not seen my device.
2. I used the wrong command. I started with fastboot, not with the command adb device. I tap „fastboot reboot-bootloader“,but the correct command is “adb reboot-bootlader“
Now i have seen my phone is unlocked, i hope i can root my android 6.

Just reboot to fastboot and flash surdu-petru version of TWRP recovery 3.0.2 with command "fastboot flash recovery xxxxx.img". And than reboot to recovery and flash supersu zip.

Can not enter fastboot mode on TCL S615

Attempting to unlock bootloader in order to root the device. Connected through ADB over TCP/IP.
adb reboot bootloader
Just performs a normal reboot.
fastboot devices
Returns nothing. I think I'm either missing a driver or the TV doesn't support entering fastboot mode.

Question I'm stumped - Fastboot mode LE2125 not responding to ADB commands

When I updated my LE2125 Oneplus 9 pro 5G to C.63 I lost root ( I tried the Magisk way when I previously updated and it allowed me to update and then preserve my root) and couldn't get it back.
So I decided to downgrade using MSM Tool and now I am on Oxygen OS build 11.2.2.2.LE15AA and I can no longer use any ADB commands when in Fastboot mode (the device does not respond), my laptop does not acknowledge using ADB Device (but it does when NOT in Fastboot mode).
The device shows Device State Locked.
When booting my phone up, I made sure in Developers options to set OEM Unlocking checked ON, as well as USB debugging checked ON.
When on Oxygen OS build 11.2.2.2.LE15AA and reboot into Recovery , I have the "Advanced" option, but not if I upgrade to LE2125_11.C.48_1480_202204082113 and rebooting into Recovery, choosing English, the next screen does not show the "Advanced" option as an available choice..
Laptop on Windows 10, have used MSM tool with my LE2125 with no issues. Anybody have any ideas?

You can't use adb commands in fastboot. You can only use fastboot commands. fastboot devices

i meant to say fastboot commands...
i.e. fastboot devices, fastboot oem unlock, fastboot boot boot.img

Then it's a driver issue

So you think it's a driver issue when the phone responds to my laptop when "Not" in Fastboot mode, and then no longer responds to commands when in Fastboot mode?...
Will try that...

Yes. A lot of people say adb works but fastboot doesn't. Usually there's a driver update in windows. Google it man. Very common

I had the same problem. After messing around with some drivers it finally started working

Damn Drivers...
I did a system restore to an earlier point in Windows 10... I then redownloaded and installed oneplus USB drivers and it worked.
