Can't root in fastboot mode - Oppo R7 Plus

Hi guys,
I have a chiness oppo r7 and I want to install an english rom. But I can't boot in the fastboot mode. I have Enable 'USB debugging'.
I tried to hold volume up and power button but it boot normally.
I tried with adb.
If I put the command line 'adb devices' I can see my device.
If I put the command line 'adb reboot bootloader' my device reboot in 'normal' mode
Do you have an idea why it's blocked? Chiness security maybe. Then do you know how I can unlock this security.
Thanks.

Stuck at Fastboot & Rescue Mode; need help

So I was trying to unlock the bootloader of my Huawei honor 6x, so I installed adb and tested it with "adb devices" and it found my phone. Next I entered "adb reboot bootloader" and the phone booted into the Fastboot & Rescue Mode. The next step was to enter "fastboot oem unlock [unlockcode]" but the cmd returned that remote access was denied. I tried it again with the same result. So I ran "adb devices" but my phone, although it was still connected, didn't show up.
So then I decided to install the Hisuite like the phone says but hisuit does not recognice the phone, but windwos makes a sound when I plug the USB in and out. I tried the restore system option but it says that my phone is not supported.
I tried rebooting it by holding down the power button, but nothing happens.
What do I do now? I have run out of ideas. How do I get my phone back?
Edit:
Managed to reboot the device by pressing all the buttons for 10 minutes. Don't know which combination worked but it did.
Thanks in advance.
While u are on fastboot and rescue mod ,long clicking the power button will reboot the device to system

Phone wont go into bootloader. How to root + flash new recovery?

Hello. I can't get my phone rooted in any way.
I want to Root so I can use TWRP app to flash TWRP recovery .img, and after that I can boot into TWRP recovery and flash new ROM. Correct????
What I've tried so far. OppoTools 1.6.5 = One key root gets hard stuck on Oppo logo at start-up and then I have to flash Coloros ROM again from recovery. Also KingRoot says app not installed. On windows version of KingRoot it gets to some percentage and then it Fails.
I have downloaded "unlocked bootloader" Coloros from this forum that was mentioned before ( Dropbox link )
I have also tried two different ColorOs versions.
I have installed 15sec ADB installer.
I plug my phone into PC and run CMD.
I type adb devices into command prompt and it detects my R7 plus.
then I try to command " adb reboot bootloader "
Phone restarts normally and doesnt go to bootloader. Tell me if im stupid, but isn't Bootloader different than Recovery? Because I can get to recovery command "adb reboot recovery"
I tried some weird button combination Vol+ Vol- + Power and phone semibricked for awhile and PC didnt even react USB driver correctly and almost waved the white flag on this case.
I've enabled USB-debuggin and OEM unlock from devices dev-options.
When I to type command "fastboot oem unlock" on command prompt is says Waiting for device. Nothing pops-up on device and nothing happens.
So now Im stuck on situation that my phone doesnt launch into bootloader where presumably "fastboot oem unlock" would work?
If you have flashed the version of Color OS that has bootloader enabled, you should simply need to go into the settings, enable USB debugging and OEM unlocking, then shutdown the phone before holding the power and volume+ buttons and waiting the ADB bootloader screen. After that, just plug it into the computer and follow the guide on flashing twrp with ADB.

Oppo A5 2020 (CPH1931) won't go in to fastboot mode/bootloader

I want to root my phone, install custom recovery and eventually a custom ROM. For this, I need to unlock the bootloader.
I have an Oppo A5 2020 CPH1931. It should go into bootloader when I press volume+ and power buttons together for 5 seconds after completely turning off the phone. But when I do this, it boots like normal. Tried all different combinations and durations. I am able to boot into recovery but not fastboot mode. I have turned on the "OEM unlocking" option in developer options.
I tried it through ADB, it says fastboot on the screen for half a second and then once again jumps back to normal booting. I also tried to already put the fastboot command "fastboot oem unlock". When it says <waiting for device> I use another terminal to try to boot into fastboot with ADB. But this does not work (also tried this with "fastboot flashing unlock").
By the way, my devices only shows up with adb devices when I select transfer files upon connecting the USB cable. When I select just charge it doesn't even show.

[LG K52] Please help !! Want to install custom ROM

Hello everybody,
I have a LG K520EMW with Android 10 Stock ROM,
According to Treble Check I have a system supporting system-as-root and a system partition A/B
So I downloaded a GSI from the phhusson's Treble Experimentations
But here are my problems :
- the phone won't boot at all on Fastboot mode (tried adb reboot bootloader, adb reboot-bootloader, both from sideload mode and normal mode, tried plugging the phone when it's off holding vol + or Vol - keys, and using QuickBoot, obviously didn't help because the phone is not rooted)
- the phone won't boot either on Recovery mode, it displays "No Command", i've tried all possible key combinations with vol +, vol -, power, camera, nothing happens and it stays on "No Command",
- Can't root with any tool, I tried KingRoot, KingoRoot, mtk-su
The only door open for me right now is sideload, I know I can type "adb sideload rom.zip" but the issue is I haven't unlocked bootloader, so I don't know what happens if I do this...
I've found nothing on the web about this phone, so if anyone have some informations or knows any procedure on another phone which would be applicable on this model, it would be great
Well, some news, i've figured out a dirty vay to access Fastboot mode, very very dirty :
I've tried, just to see what it does, adb sideload lineageOS-18.1-etc.img, and like a rabbit getting out of a hat, a recovery menu appeared and I could access Fastboot,
Now, I still have to find out why when I try fastboot oem unlock or fastboot oem device-id ( LG official procedure )
I have enabled OEM unlock in debugging options of course
On the Fastboot screen, Bootloader version is unknown,
When I try fastboot boot twrp.img, it answers "Download is not allowed on locked devices"
So, if anyone has an idea, I'd be very grateful

Hi, I have a problem... Just bought Realme 9 Pro plus, any version of Deep test not working, i'm on RMX3393_11_C.06. Any hope for unlock bootloader ? Maybe flash other firmware can help ?
Try to downgrade the firmware version from Realme Ui 3.0 to 2.0.
Is It a Global Rom?
Thanks for replay Yes global. Before update, on Ui 3.0, same behaviour. Deep Scan no recognize the device. And can't enter to Fastboot. Recovery works. How i can downgrade without Fastboot ?
