Thanks to @KineSight for his support

Do the following :
Force reboot your phone (I think Volume Down+Power)
and quickly after that you have to press and hold the volume up to boot into TWRP.
This might take a few tries but you can do it.
Once you're in TWRP Flash Magisk 20.3 (It was placed in your Internal Storage by Eureka Kernel @Chatur27)
Your phone should boot fine. You can flash Magisk 20.4 after this.

Force reboot work if i press power+vol down button

To go to download mode
Normal method
1. Turn off phone
2. Hold down both volume keys
3. Plug in computer
Bootlooping
1. Plug in to computer
2. Hold down both volume keys
For a difficult phone
1. Connect usb to computer but not to phone
2. Hold down all 3 keys
3. When it buzzes release power and quickly plug in usb to phone.
It might take a few times to get it right.
If it's REALLY BAD
1. Wait for the battery to completely run down and use normal method.

Grand Prime stuck on Odin Mode when I flashed TWRP

So I rooted my new Samsung galaxy Grand Prime (SM-G530A AT&T Variant) using Kingoroot.apk. Everything worked perfectly, then I used a Kingoroot to Supersu converter and it worked like a charm too. The problem is that I flashed the wrong TWRP recovery using flashify and now its stuck on Odin mode. I already tried plugging it onto my computer, but it doesn't detect it, therefore odin or Samsung Kies won't connect to it. I have tried different cables and installing drivers but no success. Can anyone help me???? I would really appreciate it
Here is the screen my phone is currently stuck at:

So, I have finally managed to find a solution.
what you need to do is , turn off the phone and then , press Power + Home + Volume Down and when the phone
vibrates then immediately press the volume up with power and Home.
after that you will be in a caution screen asking for either to press volume Up to start downloading and volume down to reboot the phone.
Then press volume up button , once you will do this you will again see the odin screen but this time instead of the samsung logo you will see downloading, please dont turn off the target screen will see.
What you need to do now is download odin 3.10.7 from their official website and install it on PC.
After that download twrp
go to twrp official website and search for phone and download the file
No. once download is finished, open odin in pc and select the file in "AP" and plug the phone to PC and click start, it will then complete and your will automatically start.

Thanks in advance
hold the power + volume down to reboot it and as soon as the screen goes off click the home + volume down..
if you still having trouble try to connect with the laptop with volume up as you should hear the connection sound on the laptop and help you to time it better

I fixed it, what I did was Hold Vol - Home and Power key constantly. It rebooted few times again in the splash screen. And then it took me directly to recovery. I updated bootloader again, put a new recovery. Everything is back to normal. Man, I was worried.

Hard Bricked P10 Plz HELP!!!!

VKY-AL00C00 P10, Unable to boot after a magisk 14 update, any long button press combination result in a red led flash and any long power button press result in a vibration and red led flash. Cannot boot into anything!!! Plz help!!!!!!
I have tried the HWOTA method but fastboot is impossible to access, the dload method doesnt seem to work either since there is no reaction from the vol up +down +power combo.

It was on 70 percent when i charged it first before the magisk update and i have been trying to charge the phone for a while now so i dont think so, but i am not certain as flashing tend to use a lot of battery.
I also flashed several imgs extracted from the official huawei update package beforehand and installed the magisk update in TWRP.

some solution
:crying:some solution my huawei p10 plus is dead
Here's my final solution... because the partitioning was destroyed.. i took it back to huawei customer service and because my phone was under warranty, and the fact that they could not verify if the bootloader was unlocked 'since the bootloader software no longer exist on the device' they repaired it under warranty with a free motherboard replacement...
Try the dload method if the keystroke (power button plus volume + and -)works

I could not solve
Just to be clear, none of you actually have the same problem as I did....
So in trying to fix magisk I accidentally flashed a corrupted boot.img and messed up erecovery, which will make it impossible to interact with the phone in any way except to open it up physically. As Partitioning is broken, therefore I took it to huawei repair in China, who did a motherboard for free before asking what roms I used (seriously).
If I was in one of your situations where erecovery is not broken (the thing that's tells u to download and recovery when volume up and power is pressed) in the recovery2 partition on nougat. It would be a matter of simply pressing download and fixing the problem automatically.
Also to be clear my p10 plus has been through hell as I flashed it 20 times that week due to safety net problems so it could have also been that (according to the technician) I simply fried the motherboard.
If this is not what you did or encounter then I repeat YOU ARE NOT HARD BRICKED! and there is a factory provided method for fixing your problems without resorting to flashing.
First: if your bootloader is unlocked, there will be a bootscreen telling you to press vol up to enter erecovery. If you can do that then problem solved, use the download function to repair your phone (it will lock your bootloader showing that I was never unlocked, as well as format data and all other partitions, so your will lose twrp or any custom recovery)
Btw: in oreo the recovery for huawei is located at ramdisk_recovey partition, and the erecovery partition can no longer be written to which in essence makes the china edition of these phones unbrickble as long as u didnt fry anything.
If erecovery doesn't work for you, try routing your wifi through a vpn that changes your ip to China, that will guarantee it to works as well as faster download(hicloud servers are in China).
Idk about the European and international variants but I have done this more the 40 times on my mate 9 pro and p10 plus, the only time I corrupted anything was by flashing images, SO ONLY DO FLASHING AS A LAST Resort.
