Hello comrades I unlocked my bootloader and rooted my Tecno Camon 18p ch7 by patching the boot image with magisk.
All was smoothly done in fastboot mode until I uninstalled the root recently and locked back my bootloader after rebooting I get this error
Red state
Your device has failed verification and may not work properly
Please download boot.img with correct signature or disable verified boot
Your device will boot in 5 seconds
The phone keeps rebooting(boot loop) and can't get into recovery or fast boot mode I tried countless times 
I have tried to flash it using the latest Sp flash tool in UART Connection mode with all the custom Roms and with Mediatek Bypass Tool to bypass the Auth but still can't Flash the phone
I have attached some error messages pictures 
Please help me out I really need it? any help or suggestions would be appreciated. 
Thanks
