HELP!!! 911!!! MX4 PRO won't open until boot Flyme Logo only after wrong firmware installed.

Hi? I accidentally installed/upgrade a wrong firmware after that It runs only upto the Flyme Logo Screen. I tried applying Power+volume up (volume down will just turn it off) to the screen that I should put the rightful firmware at the recovery folder that appeared on PC without clearing the data and started installing, but still it won’t open. I tried to clear data that requires the password but the password won’t even type on the screen, I can only see a dot that randomly appears at the same position at the typing area while I am typing the password.

WHAT SHOULD I DO??? Please Help!!!

@hir Its for chinese versions, any international/global versions?

@hir or still applicable on International/Global versions?
