What rooting guide did you use ? I've had a look at this oneI'm trying to root my device. Umidigi a5 pro global.
Whenever I try to root the phone, after anything involving the flash tool, I get this message on my phone.
"Your device has failed verification and may not work properly.
Please download boot image with correct signature or disable verified boot.
Your device will boot in 5 seconds."
I also had a look here in case I ever had to flash stock rom again
Might be a bit extreme for your problem though
