I flashed my BL8800 PRO using flash tool but also flashed preloader and lost my imie and was stuck in bootloop

I have recovered the phone, flashed the correct IMIE uand thge phone works now but has Red NOT VERIFY at top of screen

I have rooted the phone, installed Magisk and confirmed the phone is rooted

This did not work - file does not exist anywhere on the phone

adb shell
pm uninstall --user 0 com.android.watermark

This gave me bootloop and I had to flash the rom and start again
adb shell pm uninstall -k --user 0 com.mediatek.factorymode

I have edited build.prop as shown in this post https://www.hovatek.com/forum/thread-32527.html

ro.mtk_trustkernel_tee_support=0
ro.tee_support=0

I cannot copy build.prop back into the system folder because it is a mediatek system with a+b and recovery partition is write only

I found a version of twrp here https://www.gizdev.com/install-twrp-and-...l8800-pro/
but when I fastboot flash recovery twrp.img it failed and could not find the recovery partition no matter how I tried to flash it

I'm not certain I have the correct TWRP for BL8800 PRO the only place I could find it was from here https://www.gizdev.com/install-twrp-and-...l8800-pro/

Can anyone tell me how to copy my edited build.prop to the system file without TWRP or does anyone have TWRP that works on this phone?

Or can anyone tell me how to flash a new recovery to this phone when the recovery only seems to get created on boot?

to clarity

IF I try and flash TWRP through bootloader I get this error and I cannot figure out how to fix it

fastboot boot twrp.img
Sending 'boot.img' (41218 KB) OKAY [ 0.973s]

Sorry
Rooted boot image will load and I can use magisk to root the phone
BUT

If I
fastboot flash boot boot.img
Sending 'boot_a' (40960 KB) OKAY [ 0.957s]
Writing 'boot_a' OKAY [ 0.154s]
Finished. Total time: 1.125s

Then if I
fastboot flash recovery twrp.img
< waiting for any device >
Warning: skip copying recovery image avb footer (recovery partition size: 0, recovery image size: 42207232).
Sending 'recovery' (41218 KB) OKAY [ 2.167s]
Writing 'recovery' FAILED (remote: 'No such file or directory')

How can I flash make system folder so I can write edited build.prop back to it?

Flash this magisk module then reboot and check
