Hello everyone!

I tried to flash SuperSU with TWRP recovery, but after this my phone is in bootloop.
What should I do to fix it?

Recovery still works, and I also tried to flash system.img in fastboot, but it didn't help.
(system.img from stock firmware Tecno Camon 11 CF7 (CF7-H399BCDEFH-O-V2-190107V154) )

I'm afraid to make new mistakes

Flash the system.img via the TWRP, once you're able to boot to home screen then try installing magisk.zip instead of SuperSU, download @ https://github.com/topjohnwu/Magisk/rele...-v18.1.zip
Also, is this (CF7-H399BCDEFH-O-V2-190107V154) the phone's original build no?

No, this is the build no that I tried to flash

This didn't help. Phone just boots into recovery mode (TWRP) and nothing else

before you try flashing anything else,
do you remember the original of your phone before flashing?
and was flashing system.img in fastboot successful?

how did you even get this TWRP recovery?

No, I don't remember
No, flashing of system.img with fastboot wasn't successful
I found TWRP here, the second post

No, I don't remember

...

if you were not able to successfully flash system.img then hold off on flashing, you might still be able to find the original build number
in TWRP > 
mount /system >
open the file manager, copy build.prop from /system partition to sd card
transfer build.prop to PC then check the contents for the build number as shown @ https://www.hovatek.com/forum/thread-16005.html

Wait, I think I misunderstood the question. I meant that I flashed and this didn't help.
But I got a message that flashing is done

ok, so the old build number is gone
try flashing stock boot.img from the same build as the system.img then perform a factory reset
see if the phone boots

if it doesn't then try flashing boot and system.img from the other CF7 firmware builds @ https://www.hovatek.com/forum/thread-25781.html
perform a factory reset then see if the phone boots

I flashed boot from the same image, then factory reset, it didn't help. After I flashed boot and system from other build, it didn't help as well.
Phone just boots in TWRP recovery.
