Ekavun, you don't need to unlock the bootloader and you don't need TWRP.
You only need to use flash tool to extract and flash back your boot partition. You can't use adb to do that.
I asked blackview 4 months ago to publish the stock ROM. They never did.
I extracted the stock ROM myself and saved all update.zip as they came.
I can provide the original boot image for your ROM version (or even the Magisk patched one if you want), but you will still need to flash back the patched image with flash tool.

I would be most grateful for the rom and the patched image. Now that the boot loader is unlocked, I can flash the boot image from Fastboot. Is that not safe to do?


Thank you!

Yes  i patched the boot image with magix.when i try to flash the patch error PMT changed it must be downloaded.please selectgormat all *download scene and try again

Why didn't you said that in the first place instead of "no don't work" ????
And no, you don't have knowledge in flashing apparently.
The scatter don't match your phone partitions. Post the full version of you build (Settings > System > About phone > Wireless Update) and the scatter you used.

Did you use SP Flash Tool version 5.1828 ?
Did you select Download Only option ?
Did you uncheck every other partitions and only select boot image ?

You can try
BV6800_PRO_MT6750_V1.4_20181130-1918_scatter.zip
(1.3 KiB) Downloaded 436 times
but it should work with the first one.

The numbers are different because I use an old version of Magisk.
I don't understand why you have this message. It works perfectly on my phone, with this same scatter.
You can try to extract your full ROM : same as the boot image but size 0xE8F800000
It's very long and you need at least 60Go of free space on your drive
Then reconstruct your ROM and scatter with WwR MTK.
