are you using Windows 7/8/10 ?
did you boot into bootloader mode?
(adb debug mode is for adb and bootloader mode is for fastboot)
interaction is: adb reboot bootloader (when device is on and adb debug is on)

Question OPPO - Can't enter to fastboot mode, even if my bootloader is unlocked !!! HELP

Hello,
I have a problem : when I try to access fastboot mode (with adb reboot bootloader command), there is an error : "The serial is not match, Fastboot_Unlock_Verify fail" and my phone reboot 1 sec later.
The real deal is that I can't access recovery and download mode, because I can only access recovery from fastboot that doesn't work, and I can enter download mode only from recovery !
My final goal is to root it by flashing my patched magisk Boot.img, because TWRP is not available for my Oppo A94 5g device.
I can only go to DROM mod, how to unlock for good fastboot mode or flash an img file without Fastboot/Recovery/Download mode ?
Does anyone knows an issue ? In any case, thanks for your help.
I'm having same problem with no error tho... (How did u get the error btw?? On phone screen or on PC?)
Appearantly OPPO has "disabled" fastboot somehow...
We'll have to wait for someone to find a workaround possibly.
I get this error when I try to enter recovery mode (Volume - and power button)
Maybe we are in "demo mode" with no access to fastboot... but unlocked bootloader, and that make an error. I don't know.
Update
I found a solution, using SP flash tool, it uses DROM mode to flash my patched boot file.
