Question OPPO - Can't enter to fastboot mode, even if my bootloader is unlocked !!! HELP - OPPO A74 5G

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.

Booting to fastboot but how?
Hold volume down and power button simultaneously until you see a white screen with android logo and "Fastboot & Rescue Mode"
you will also see whether your phone's bootloader is locked or unlocked,if locked then you have to unlock it from Huawei website before flashing any thing

I'd recommend you to turn off your device and flash ZUI via QFIL. Then unlock bootloader and flash TWRP and whatever ROM you want.
ZUI 2.1.049 QFIL
Bootloader unlock on zui

Create a folder and insert a twrp file (for example twrp.img). Then type fastboot boot TWRP.img . If it allows you to do that then you'll get into TWRP. This will probably won't work, so I think the only thing is left is to repair that power button to make an installation via QFIL.

Bricked A2 only fastboot

Hi guys, i need some help, i wanted to convert my A2 in 6X, and i need to enter edl mode to do this. Because i couldn't enter edl via fastboot or adb (i had unlocked bootloader ad twrp recovery installed) i tried to relock bootloader (maybe this was the error), now i'm stuck at message that says that system is corrupt and devices wouldn't boot, i can only access fastboot, tried to boot twrp via fastboot but didn't work, fastboot getvar unlocked return no, now i'm trying to follow the guide to unbrick from ARB but phone should be in edl mine is in fastboot, please help me, any suggestion is accepted! Thanks
https://forum.xda-developers.com/mi-a2/how-to/mi-a2-toolkit-unlock-bootloader-root-t3834585
use option 5 then select the second option
it will boot the device into edl mode.
if you have issues with it not letting you enter it with this then try to unlock the bootloader again.

Redmi 4 (Santoni) bricked. Please help.

I unlocked my redmi 4 (Santoni) boot loader and flashed pixel experience ROM (https://mega.nz/#F!INZgnAZI!9fuWhfCuazOO5YPBjxGlmA). It was working fine for a few days (Small heating issue was there). Then one day while i was charging the phone the phone turned off and never turn back on. When i try to switch on the mi logo flashes for a split second and then turns off. I tried to get into recovery but couldn't.
I can get into fastboot mode. I tried flashing the phone using Mi flash tool and fastboot rom. But it shows an error "flash tz error". When i tried an old version of mi flash tool i get the "Unspecified error (0x80004005: FAILED (remote: Critical partition flashing is not allowed))

Have you tried installing TWRP via fastboot?
I had the same exact problem, i put my phone on charge & when i came back to check it was switched off. It wouldn't turn on except the mi logo. I tried to flash through fastboot turns out my bootloader was re-locked for some reason. I had to re-unlock it then proceed on to fash fastboot miui rom. Check if your bootloader is locked or not.

This is a good idea! Probably u first try to install trwp in fastboot mode. If this doesn't work try to unlock bootloader again and then install trwp.
When all these Option doesn't work u still can open the phone and use edl fastboot mode to flash miui again.

Tried unlocking boot loader and was not successful because the phone was bricked. My only option was to use edl test point. Now i installed miui 11. (Aprart from some minor bugs which can be eliminated by reflashing some other roms) Thank you guys. Now my phone is successfully unbricked.
For somebody who is having the same issues,
My phone (Redmi 4_Santoni) was completely bricked. The only thing i can access was fastboot by pressing the volume down + Power button combination. But i could not install twrp or any other recovery because my boot loader was locked. I got it fixed completely with the help of you guys (Thanks again) and i want to share the procedure i went through.
Condition: Completely bricked with only fastboot access, Locked bootloader.
I tried this video (https://www.youtube.com/watch?v=j27x5iJSS40) but failed because i could not access recovery. So my only solution was to use edl test point flashing. I followed this guide https://forum.xda-developers.com/showpost.php?p=74818435&postcount=3. It was very easy to do. But in the device manager (Press Windows key + R and then type devmgmt.msc and press enter) instead of showing "Qualcomm HS-USB QDloader 9008", the device is shown as "Qualcomm HS-USB Diagnostics 900E". The problem was you have to plug in in USB cable while the test points is being connected with a pair of tweezers or a paperclip as shown in the link above.
Make sure you already downloaded the latest mi flash tool from here https://xiaomiflashtool.com/ and download fast boot rom from the official website. (Go to https://en.miui.com/ Click rom downloads. Click flashing guide. Download the fastboot rom from there for your device.) Now flash your device using mi flash tool and voila. your phone is unbricked.
Thank you guys..

edl mode 9008 v40 very easy

(french) hello
I could not start in edl mode with the xda instructions but I found a videos
phone on android, connected to the computer by usb. you keep pressing the power button and the volume down button.
when the screen goes black immediately you strafe the volume + button for 2 sec.
the secret is the windows song if the phone is on. when you hear windows song strafe the volume +. i know I did it with my phone off and my phone on quite a few times
normally your computer will recognize the phone in the correct mode. if there is a problem do not forget to install these drivers and restart the computer as it will stay in edl mode and will be well supported.
QDLoader HS-USB Driver_64bit_Setup
MediaFire is a simple to use free service that lets you put all your photos, documents, music, and video in a single place so you can access them anywhere and share them everywhere.

that's funny visibbly before you unlock or reflash the original bootloader the phone don't have fastboot mode with me. but fastboot don't work well in windows. it work erfectly on linux ubuntu with me at exemple.
thanks for your attention
yeah, it is very easy
So this is how you go into fastboot ?

But you can get to fastboot, just not the way you read on the internet.
The device doesn't have fastboot available, until, you put it in edl mode and use qfil to flash the 'engineering' abl. That's what gives you fastboot.
You could, at that point, use fastboot to get the info for unlock.bin. But why? because at that point you can just type 'fastboot oem unlock', and it's unlocked.

Unlock only works with Oreo ??
I have Pie
How do I downgrade without root ?
Is it possible ?
If I can flash a firmware without root
I'd be more than happy to flash a custom rom which has LG's apps instead of Google annoying ones.
