I tried to root my device Walton primo R6 MAX with the trick but failed

[shezan]

I'm using a device name: walton primo R6 MAX
Chipset: Unisoc SC9863A
Android: 9.0
Ram/Rom: 3/32
I tried to root my device so I signed my vbmeta with the help of  a post from hovatek and I was successful. Then I ported my recovery.img from TWRP auto porter that support android 9 then I signed the ported recovery and flashed to my device via fastboot and spd research tool. Flashing with fastboot can't be open on recovery unless I'm on homescreen but as the post they say first to go on the recovery mode. And if I flash with spd research tool then I can Go simply recovery mode but It stuck on boot logo and do nothing else.   
And then I flash recovery that is patched with magisk. I did the two method like before and I got just a bit different  result than before. In the recovery mode I can just see "modem-int" written in a pinky red screen. 

So if you can help me root my device I'll be very thankful to you.

You are supposed to patch your boot.img with Magisk.

But then I'm unable to flash the file... Even after I signed the custom boot image I can't flash the file... It just stuck on writing...

when creating your custom vbmeta, you're to replace the keys for both boot and recovery since you already know that you will tamper with both partitions. if not then you'll get stuck in fastboot writing
for root, try patching boot.img using magisk canary @ https://www.youtube.com/watch?v=ZGLWoJ-POlA and signing using your key
if that doesn't give root then patch and sign recovery.img
