here is another way.
please try to do as follows:
disable all the wi-fi connections in the radius of the phone (because from the phone the wi-fi can not be disconnected), skip the procedure for the SIM, at this point it will ask you if you want to continue without connections and yes, do not enter the name and surname to give the phone a name, accept the Google / Android agreements, at this point the phone will be activated, no update is necessary via OTA if you have the BV9000 PRO-F phone (full HD version). There are two versions of this PRO series phone, the BV9000 PRO (not full HD) and the BV9000 PRO-F (full HD).
I hope this solution will work for you too.
