My OnePlus 7T is unlocked already. "This mobile device is permanently unlocked and can be used with any carrier!"
But as instructed to go to fastboot mode and get the unlock code, there is no unlock code in that screen, whether I enter it via Power + Vol Up or adb from computer.
Someone please help, any other way to get that unlock code from my phone?

Bro, OnePlus asks for the Unlock Code before they can issue a Unlock Token.
At least, that's how they do it now, unsure about what happens previously.

Connect your phone to your computer and open up a command window and type:
fastboot.exe oem get_unlock_code
I don't remember if it has to be in fastboot or just plugged in. But plug your phone in, type the command and see if it works. If not, maybe you have to be in fastboot. But when it it works, it will output some info and you will see a long sequence of numbers and letters in the command window. I remember it was two lines of stuff. That's what you need to copy and put into the OnePlus site.

Your 7T is missing necessary usb driver (I faced the similar problem and then solved it). Google fastboot driver windows 10 7t and install the driver. I followed the following guide "https://www.androidusbdrivers.com/oneplus-7t-usb-drivers/". Hopefully your phone will be recognized in fastboot now.

Hey all. I'm in a bit of a pickle. My Tmobile LG g4 has stopped fast charging. When I plug in any cable, I do NOT get the USB notification which allows me to connect to my PC. Enabling the MTP option in the Dev options still does not allow the device to be connected to the PC to flash back to stock for warranty support.
Is there any way for me to save something to the SD card to reset back to stock? Do I have to connect it back to stock or at least relock the boot loader?
I've tried multiple PC's and multiple cables with no success to get the device connected. When connecting to a PC, I get. The device has malfuntioned on my machine.

does it go into download mode.? phone off vol up key and connect usb.?
if you want to remove unlocked bootloader follow this comands
UPDATE:
I was able to Lock the bootloader.
1. I connected the phone to my PC
2. Powered on the Phone (it took a few tried of pulling the battery and powering on)
3. Check the box for OEM Unlock in Dev. Option
4. Use Minimal ADB and Fastboot and type in
Quote:
adb devicecs
- you should see the phone listed as one of the devices in the command line window
Quote:
adb reboot bootloader
- phone should reboot and you shouold see 3 lines of text on top
Quote:
fastboot oem lock
- nothing will happen on the phone, but on in the commandline it should say that it is done
Quote:
fastboot reboot
Phone reboots and the boot screen does not show the unlocked bootloader message anymore
Unfortunately, the computer will NOT detect the phone. No computer will. Using a USB cable that came with it , no luck either. Any ideas?

so basically theres no comunication with phone. not really. unless you go and exhcnage it to tmobile, so you cant remove bootloader unlocked message either. if you lucky and tmobile doesnt check for it then you may be able to get it exchanged. as it not recognized in any computer ill say its hardware problem. good luck.
Hi Folks
I just got the Media Pad M2 8.0 and I want to check if the bootloader is locked or not
because there is no dialer installed I can't use the code I found in other forums
is there another way to find out?

Yes, there should be. You need to enter fastboot mode on the phone - i.e you need to get into the bootloader screen. The bootloader screen (usually called fastboot mode) will tell you if the bootloader and FRP are locked or unlocked - If it is locked, you should see "PHONE Locked" and "FRP Lock" in green, otherwise it should say "PHONE Unlocked" and "FRP Unlock" in red if the phone has been properly unlocked.
You can enter fastboot mode by either using ADB ("adb reboot bootloader", first make sure to enable developer options first as detailed in the Rooting guide, and then enabled USB debugging), or by first shutting down the phone and then powering it up while holding down the VOLDN (Volume Down) key. Of the two methods, I'd recommend the ADB method because the hardware keys method is usually hit-or-miss for me - sometimes it takes me to the bootloader, sometimes it boots normally into the ROM.
If you're on Windows and need the ADB and fastboot binaries, you can install the "15-second ADB installer" found in this thread.
Thanks, that worked, took me a while to figure everything out...
and it appears that my device is unlocked...
I just bought an LG G7 Thinq LM-G710AWM (Canadian Model) and for some reason I can not get into the fastboot menu either manually or through adb and fastboot command prompt commands, I have no idea how i go about this because it seems weird that fastboot is just straight up disabled on my model, anyways hopefully you all can help

No my phone just reboot instead of going into the fastboot menu, I can send a video or something if that helps at all?
You can't access it because the bootloader is locked. Don't waste your time even trying.

Probably this is forbidden for US models and allowed on european models (or just italian, like mine), get a look here https://forum.xda-developers.com/lg-g7-thinq/help/version-g7-unlock-bootloader-root-t3810213
In fact, I was able to go into fastboot mode (phone off, connect the USB cable while pressing vol down), even with locked BL.
Then I can send the command "fastboot devices" and it shows me the serial number of my phone.
The reason why fastboot mode is active with BL locked is that it's just through fastboot that you can unlock the BL. The instructions to do this appear just on the phone display as soon as you enter fastboot mode.
Hi,
I'm after some advice, how do I place the Moto G5 in Qualcomm mode or EDL mode.
I have entered the bootloader by holding down and turning the phone on, this allows me to use fastboot.
From there I can scroll down to QCOM, but when I press the power button it boots into the normal system instead of EDL mode.
I have also attempted from within fastboot to use:
fastboot oem edl
fastboot oem qcom-on
fastboot reboot emergency
and
fastboot reboot-edl
Although non of these have been sucessful.
I also have access to an EDL cable, although, when I plug the phone in, then flick the switch 10 seconds later, it does not enter EDL mode, it just charges.
The phone sometimes shows as File Storage Linux USB Gadget in device manager, although it is inaccessible, I have updated the laptop to use the qualcomm drivers, although I don't think it will ever recognise it if I can't put the phone into qualcomm mode to begin with.
Any help would be much appreciated.
What are you actually attempting to do?
This mode is generally used to unbrick a device but you have access to the bootloader/fastboot mode and you wouldn't use edl mode to unbrick this device anyway
It's also used on some device to unlock the bootloader but again you wouldn't do that with this device
So without knowing what you are trying to achieve I can't give you any advice
Technically if you start the phone normally then enable usb debugging in dev options then connect phone to PC and in a terminal window where you have adb set up type
adb reboot edl
Not all devices support this mode though and I've no idea if this one does

Without going into too much detail as to why, there are tools I have access to which can be used to take a full back up of the entire memory block of the phone when it is in Qualcomm mode.
I cannot access adb on the device to use "adb reboot edl" so I am limited to either trying to activate Qualcomm using a button combination or via fastboot, unless you can advise another way.
Any help or a point in the right direction would be much appreciated.

Sounds dodgy to me - sounds like you're trying to access data from a phone that isn't yours so I won't be helping

It's not dodgy, but I fully understand.
Thank you anyway.
try fastboot -i 0x2b4c oem reboot-edl (it's working for LENOVO ZUK Z1 and ZUK Z2)
You can try (if you can/have the TWRP image) to flash TWRP and in reboot options select EDL.
In case the bootloader isn't unlocked you can also use fastboot boot [TWRP image name] to boot directly into TWRP without flashing and then repeat, go into reboot options and select edl.
Not sure if it works for you, if it does let me know that I have helped!

I need help too. So, I own a Moto G5s plus sanders. I unlocked its bootloader the day I got it. Didn't keep any backup and rooted it. I Also installed dot os based on android 11. But my 4G Volte connection was finicky. So, I decided to use a Volte zip patch. But, anyways I flashed the zip via TWRP and tried to reboot. But the phone didn't turn on after that. After a few minutes to my shock I understood that I hardbricked my mobile. No button combos, nothing worked. Anyways in my desperation I found a YouTube video showing the use of blankflash to revive a phone and lo and behold I used the procedure to again restore my device. It booted to the fastboot interface. But my happiness was short lived. My baseband was unknown at this point and the bootloader was I dunno downgraded to 0.5 inplace of 2.12. But, more importantly the unlock status was lost. I unlocked it again and all went well. I could even flashed TWRP. but then I realised I couldn't upgrade my bootloader. I couldn’t do anything. It's always gives a "security downgrade", "preflash validation failed" and "permission denied" error. I even tried RSA official rescue tool from Lenovo but even it was unsuccessful. It was never unsuccessful before that. Not even with a unlocked bootloader. I researched for days and tried custom ROMs. I flashed stock images. Nothing brought back my baseband and IMEI. When I type "fastboot oem unlock critical" it gives me permission denied error with a message. "Need OEM signed bootloader." I think the blankflash bootloader is the root of all evil. I need to change it and therefore I need to enter the edl mode. I have tried all adb commands and fastboot commands. The phone reboots okay after those commands but never goes into edl mode whatsoever. I am also ready to do a controlled hardbrick of my device to go into the edl mode so that I can use my device again with a proper bootloader and a properly working fastboot. Please help
Hello, I'm having some serious trouble bootloading my Kyocera DuraXV Extreme (AOSP)
I've went into developer options and activated USB debugging and allowed OEM unlocking.
But I get stuck on rebooting into bootloader mode. I've tried different approaches:
1. Starting up phone while holding volume up and down buttons. Then select "reboot to bootloader".
2. adb reboot bootloader command
Both options reboot the phone without going into bootloader mode.
Seems Kyocera decided to somehow lock the bootloader mode. Anyone know of a workaround here?

My comments below are based on the belief that you are trying to unlock the bootloader.
I am not familiar with this phone but generally the two steps mentioned by you are not enough to unlock the bootloader. After those steps, you'll have to issue a command via adb to unlock the bootloader and if successful, then you can boot into it for further operations. The command will vary between devices, so search and profit.
Thanks, this cleared it up a bit, you are right, I'm trying to unlock it.
I'm trying the command fastboot flashing unlock but only getting the message < waiting for any device >. I read somewhere that I might need some USB drivers but I don't know where to find them. I have the latest version of the standard USB drivers for the phone, but as I understand it I need special drivers for this?
I'm trying to follow the steps here: https://www.ifixit.com/Guide/How+to+unlock+the+bootloader+of+an+Android+Phone/152629#s317298
I get stuck on the step:
Enter the command adb reboot bootloader
Wait a couple seconds until your device rebooted into the bootloader, then enter the command fastboot flashing unlock
My phone isn't "rebooted into the bootloader", it just reboots. It gives the message "< waiting for any device >" when I write fastboot flashing unlock

It should be a driver issue. When the phone is on and you connect it to the PC/laptop and send the command 'adb devices', does it show an alphanumeric value? Likewise, when you are booted into the bootloader by key combination and send the command, 'fastboot devices', does it show the same alphanumeric response? If so, the drivers are installed properly. If not, either you don't have the correct drivers or they are not installed properly. Try installing the drivers again after disabling driver signing in Windows on your PC (search for it on Google).
Hello, can you clarify what you mean by "booted into the bootloader by key combination"?
My problem is I cannot boot into bootloader at all.
Any attempt at doing so results in a normal boot of the device.

I see Power plus Volume Up as the suggested one from a Google search. Try that.
If you can't even boot into the bootloader with the correct key combination, I don't know how to help you further since we are starting to go in circles. I am sorry.
Hello, thank you so much for trying to help me. It seems I can't boot into bootloader. Volume up + power gives the same result as what I did before.: It opens a "Recovery" menu where I can choose reboot to bootloader, but this option just reboots the phone.
I've been in contact with Kyocera and they say:
Thanks for contacting the Kyocera Customer Support. We will be more than happy to assist you with your concern
In this case allow us to inform you that since this device is a basic phone , it doesn't have the option to activate fastboot mode. By installing something that will change the way the phone works , that will void the warranty that came with the phone. We as manufacture can not help you to modify the software that came with the phone.
So the phone's fastboot mode has been deactivated. But since it's an android I guess it should still be possible with some workaround. I just don't know whee to start, I've been researching for a week with no result.
Something interesting ehre, maybe someone with more coding knowledge can tell what's going on.
I found the source code for the phone and located a file called recovery.c which I guess handles the menu I see when I press volume up + power button. Maybe some clue to why the phone isn't going into fastboot mode?
