[Q] Relocking bootloader mac problem

Hello I am trying to relock the bootloader on my GN with a Mac. I am at the very last step where I have already unrooted and just need to reboot into the bootloader to relock it. Problem is, my volume down button is broken so I can't get into the bootloader that way and every time I put the command ./fastboot-mac reboot-bootloader, it keeps saying <waiting for device> Please help I need to return it because my volume down button is broken!

i dont know mac but.... you can do this several ways
1) adb reboot bootloader [ensure usb debugging is enabled]
2) download terminal emulator from market and open it and type in "su" (grant it access), then "reboot bootloader"
3) your ROM.. holding down power, may have "reboot" on it select bootloader.

You can't use fastboot commands unless the phone is in fastboot.. therefore, ADB reboot bootloader or the other two methods mentioned above.

[Q] How do you access fastboot?

Hey everyone, so about a week ago I decided to flash the wrong rom (not intentionally) on my phone. I used the LGflashtool. Now I cannot access download mode at all and when i turn it on all it does is stay on the LG logo. When I turn on the phone and i hold up the volume up button it starts up fastboot and looks like this
[40690] Fastboot Mode Started
[40780]---reset--
[40780]---portcharge---
[40990] fastboot: processing commands
but when i try to run the command "adb devices" in the command prompt (C:\Users\chris\AppData\Local\Android\sdk\platform-tools (folder path)) it does not show my device at all. Also when i try to run the command "adb reboot" it says "Error: device not found"
Is there a way for my computer to see my device?
Thanks in advance

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!

Should be connect the charger cable to the phone.

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.

problem with fastboot twrp flashing

my device came with unlocked bootloader, so I tried to flash twrp but every time i type "fastboot flash recovery C:\adb\twrp-3.2.1-3-whyred.img" and hit enter, the device seems to disconnect from pc and there is "press any key to reboot" in fastboot on my phone.
How can I solve this issue?`
Phone gets detected by adb/fastboot tool so its not a driver problem. I tried different cables and usb ports aswell.
Firmware is latest global stable.

Well if you already had adb in your pc, rename the twrp file to recovery, you don't have to move the twrp from download folder, open download folder press shift and right click then select open cmd here, on cmd type "adb device" to see if your device connected, then after that type this "fastboot flash recovery recovery.img" press enter than after that type "fastboot boot recovery.img" TEAMWIN logo should appear on your device and then you can unplug your device. Hope this useful

i am trying to flash twrp there is no folder called adb i have installed the 15 second adb and all so i have got this minimal adb flashboot and i tried with that and got this ---- FAILED (remote: Flashing is not allowed in Lock State). i have granted all usb and oem unlocking. please help with this

Phone shows unlocked during the boot?
I had the same Problem,after a Factory Reset works for me.
I am on Miglobe-Rom Miui10 8.6.28.
Minimal ADB is enough.
Or use this from Attachment.
Unpack with Win.zip and copy Twrp in this Folder.
Conect the Phone with your Pc ,boot into Bootloader and click "cmd-here.exe"
Use this Command
fastboot flash recovery twrp-3.2.1-3-whyred.img

@Nazukii - Quick question - any chance you could try running GameBench on your device, and see if our background service dies when the device is disconnected from the PC? I don't have a Note 5 Pro to test, and I've got some user complaints. Any assistance would be awesome!

Redmi Note 5 pro
So my Bootloader is locked,
My phone stuck in MI recovery idk how.
I cant install MIUI via fastboot. Im stuck ..
Can anyone please help me here not sure how to proceed further.

If you have made sure that you have all the drivers installed and still have not solved, you need to use an Intel-based PC / notebook and use a usb 2.0.

”Well if you already had adb in your pc, rename the twrp file to recovery, you don't have to move the twrp from download folder, open download folder press shift and right click then select open cmd here, on cmd type "adb device" to see if your device connected, then after that type this "fastboot flash recovery recovery.img" press enter than after that type "fastboot boot recovery.img" TEAMWIN logo should appear on your device and then you can unplug your device.

In fastboot mode, message "OTG NOT MOUNTED, File NOT FOUND"

I have used the SDK tools trying to root my M9.
Activated developper mode, OEM unlocking end usb debugging.
In bootloader mode I can use the command line "adb devices" and it list in terminal a number for the device.
If I do the same in fastboot mode ("adb devices" at command line) then it doesn't show any device number and keeps searching.
When in fastboot mode I got the following message:
SD MOUNTED
OTG NOT MOUNTED
File NOT FOUND
Can somebody help me to solve this issue pls!!

Why don't you just install twrp using fastboot then flash magisk?
