One thing that was different.

After it finished recovery, I quickly unplugged the usb before my PC could recognise my phone and before my phone finished restarting.

Possibly after phone rebooting the first time, my phone tries to send a package to hisuite but it didn't get the right response or something which causes it to have an invalid signature or something.

So yeah I got it fixed now with EMUI 10

Thank you guys <3

Thanks for you hisuite proxy tool! the recovery works like a charm.

One thing to either update or add to your wiki instruction is to not let the phone plugged to the PC once it's done. I think after the first installation, it was sending a packet to hisuite but the proxy didn't give the correct response, hence I got the error message "your device has failed verification and will reboot."
