Hello comrades I unlocked my bootloader and tried to root my Tecno Camon 17 pro cg8 by patching the boot image with magisk.
All was smoothly done in fastboot mode until I reboot and got this warning
Orange state
Your device has been unlocked and can't be trusted
Your device will boot in 5 seconds
The phone keeps rebooting(boot loop) and can't get into recovery or fast boot mode
The boot image I patched was the V537 here on hovatek since I couldn't back up my rom
I have tried to flash it using the latest Sp flash tool in UART Connection mode with all the custom Roms here and with Mediatek Bypass Tool to bypass the Auth but still can't Flash the phone
I have attached some error messages pictures 
Please any help or suggestions would be appreciated. 
Thanks

Because u did not disable DM verity
Pls flash back ur stock boot image

If u insists on getting root pls disable DM verity by
downloading vbmeta on https://www.hovatek.com/redirectcode.php...c0g3NS1CZw== and copy it into ur adb folder . running this command in fastboot
adb devices
adb reboot-bootloader
fastboot devices
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
Then u can flash ur Patch boot and after that rerun the command
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

i unlock bootloader === fastboot unlock flashing
REBOOT all good
flash vbmetta === fastboot flash vbmeta vbmeta.img
then
i flash the patched boot === fastboot flash boot boot.img

And i cant get to fastboot mode or bootloader as i said

Try reflashing the empty vbmeta
And retry the root process using mtkclient

You should first do a full backup using https://www.hovatek.com/forum/thread-40865.html so we can ascertain the original build number.
Are you certain you flashed empty vbmeta from method 3 @ https://www.hovatek.com/forum/thread-32719.html, not the one from stock rom?

OK I hv downloaded the empty vbmeta will that stop the bootloop issues

Anyway I'm dumping (making a full backup) the rom
But the userdata progress is very slow it is left with 5 hours
For it to finish as at now ?

Thanks tho but I need a way off the bootloop issue

I flashed the empty vbmeta but still It is bootlooping

Also when backing up the rom the user data part took a long time
and still gave errors the user data alone was around 138gb when the error occurred so I have deleted the userdata from the backup rom the rest of the folder is about 8gb

So should I try to flash the hovatek roms with the mtk client
Or there is a way around the boot loop issues
