My phone is not entering fastboot mode
I just want to check whether bootloader is locked or unlocked. I am using Minimal ADB and Fastboot which I downloaded from https://androidmtk.com/download-minimal-adb-and-fastboot-tool . I am following instructions to check bootloader from https://www.alphr.com/check-bootloader-is-unlocked/ . Everything is fine until I enter into Fastboot mode on my phone. (I enabled USB Debugging and revoked usb debugging authorization in Developer Options). I can see my device after running
adb devicesin cmd. But when I run
adb reboot bootloadercommand, it just reboots in normal mode. It doesn't enter to fastboot mode. I aslo tried
adb reboot fastbootbut it also didn't work. That means when I type
fastboot devices, I don't see anything.
What should I do to enter Fastboot mode so that I can run
fastboot oem device-infoto see my bootloader information?
Note: My phone is Oppo F11 and it is running Android 11. I am not familiar with adb commands.
Oppo F11 has non-unlockable bootloader, fastboot is disabled intentionally. You can root with https://www.xda-developers.com/mediatek-su-rootkit-exploit method only, but carefully read instructions especially respect all warnings
