Hello, my device is J7 2016 (SM-J710FQ) I installed twrp through odin and flashed custom ROMs but I didn't unlock the bootloader and I need to unlock now but since I use custom rom there is no "OEM Unlocking" option in developer options. I followed some guides and threads but I couldn't make it.
Here is what I did:
-Installed latest drivers for my phone
-Installed adb and fastboot
-Installed adb and fastboot drivers but I cannot change the driver. My phone is detected as "Samsung Mobile USB Composite Device" in fastboot and when I try to use the "Android Bootloader Interface" driver an incompatibility error occurs and driver doesn't change.
-My computer has Windows 10 in one disk, Mac OS in one disk and Windows 7 as virtual machine. I will install ubuntu alongside Mac OS.
Please help me to unlock bootloader / use fastboot

You already unlocked your bootloader by enabling the OEM Unlocking option. If you hadn't unlocked your bootloader, you wouldn't have flashed twrp and custom roms. Why do you want to reunlock it again?

Hi
I've had some hard time trying to unlock my GT-I9060I's bootloader (so I can install unsigned custom ROMs) but I didn't succeed.
Thins I've tried so far:
Installed Android SDK
Installed ADB and Fastboot drivers
Changed the android driver to Android Bootloader Interface
The problem seems to either be my computer not recognizing the phone in fastboot mode or simply my phone not booting in fastboot mode (even though
HTML:
adb reboot bootloader
rebooted my phone)
How can I unlock my bootloader?

how to unlock the bootloader in Realme 5i RMX2030
Here is a good guide that worked for me to unlock the bootloader:

The root part didn't work, Magisk complains about unknow boot image format

I've done the in-depth test and it's on the Fastboot screen but when I type fastboot flashing unlock in a command window it just shows me the help text for fastboot, which doesn't show any command or option for either flashing or unlock, so how can I get it to work if those aren't valid commands?
fastboot devices shows my phone, so the device is recognised.
EDIT: I'm still on Android 9 A.15. I understand that there's no unlocked for Android 10 yet.
EDIT: Nevermind. I was using adb/fastboot from the link in this guide, which is v1.3 https://www.ytechb.com/how-to-root-realme-5i-and-unlock-bootloader/
After I updated to minimal v1.43 from here it worked https://androidmtk.com/download-minimal-adb-and-fastboot-tool
My problem was same. But i successfully downgrade to color os 6. I guess you can try it too.
Enable USB Debugging and Allow unlock boot loader option in USB debugging.
Connect your mobile with PC and use following Command.
adb reboot bootloader
fastbook flashing unlock
Check mobile for unlock option.
How did you downgraded to colour os 6?
I'm trying to root my realme 5i that i upgraded to 10.

what's the next step
I just purchased a OnePlus Nord N10 5G (BE2026)
Originally it was running OxygenOs 10.x.x.x
Following guides from oneplus website and here on XDA I was able to successfully unlock the bootloader and of course ADB worked fine as well as Fastboot in the bootloader etc...
After unlocking the bootloader I realized that OxygenOs 11.0.2.BE86AA was available via OTA. Which is now what the phone is currently running.
***MAIN ISSUE***
after unlocking the bootloader in order to gain root access via TWRP and Magisk my PC fails to find any devices while the phone is in Fastboot mode... ADB still works just fine but as soon as I run "adb reboot bootloader" or boot to bootloader via buttons the PC will not detect the phone any longer while in the bootloader or Fastboot mode...
I have triple checked that:
SDK USB drivers
ONEPLUS USB DRIVERS
Windows Universal USB drivers
USB Debugging
OEM Unlocking
PC is granted developer access
newest version of ADB & Fastboot
and everything else I can find on this issue searching Google & XDA for the past 3 days
* one issue that I found strange, only when the phone was booted into the bootloader Windows device manager showed Android as an unknown device. Which I could only solve by using Zadig and installing Winusb driver... but still running "fastboot devices" while phone is in bootloader / Fastboot mode still shows no devices....
I've been trying to solve this about 4 days now scouring the internet for any information I could find and nothing seems to work. But everything worked just fine before I unlocked the bootloader / flashed OxygenOs 11 via OTA and now windows to see the phone while in the bootloader....
When phone is got booted into bootloader / fastboot mode then phone can't get seen / accessed by ADB. Point.

@jwoegerbauer not entirely sure what you are trying to imply with your message...
If you are trying to point out that ADB doesn't work in bootloader / fastboot mode, I am completely aware of this. And never mentioned otherwise in my original message.
With my phone booted up into Android
And I run "adb fastboot bootloader" the phone will reboot into bootloader mode but my PC still shows waiting for devices... Or if I boot into bootloader / fastboot mode manually and run “fastboot devices" it shows no connected devices. And no fastboot Commands work either... I am not trying to run ADB Commands in fastboot mode.
AFAIK starting with Android 10 the command sequence should be as this
Code:
adb devices
adb reboot fastboot
fastboot reboot fastboot
fastboot devices
...
fastboot reboot
because fastbootd got moved to Android's userspace.
So I want to unlock the bootloader of my poco f2 pro. I installed minimal adb and fastboot, google usb drivers and the mi unlocker tool. Adb does register my device, fastboot will only recognize my device if I use the adb reboot fastboot command. If I use adb reboot bootloader fastboot wont recognize my device and the device manager will show a missing driver. The unlocker tool wont recognize my phone neither in fastboot nor in bootloader mode. I tried using the xiaomi usb drivers but they appear to be too outdated (2011) or something else but I cant install these drivers. Any ideas what driver to use or how else to bypass the problem? I also tried reinstalling minimal adb and fastboot while my device was in bootloader mode hoping it would install the driver but still no success. The drivers coming with the mi unlocker tool were also useless. To rule easy things out, I tried different ports, cables and even pcs, every time the exact same problem. Usb debugging and oem unlock were obviously enabled and my device is registered for unlock.

Delete all drivers.
reinstall them.
All my drivers are 2016(W10/W11).
Try another version.

I would like to unlock the bootloader. I've enabled "Developer Mode" , "USB debugging", and "OEM unlocking". I also installed Minimal ADB and Fastboot on my Windows 10 PC. In the ADB and Fastboot terminal, it shows up as an adb device. "adb reboot bootloader" just causes the device to restart. I've only found 2 other guides, both of which are inconclusive. I've already unlocked the device with AT&T but that didn't solve my inability to unlock the bootloader. Any advice would be helpful.
