You Must provide a video proof; this video proof must be compliant with these rules:

First type *#06# (or any other way of displaying the IMEI on the phone’s LCD) on the phone then wait 5-10 seconds until we can clearly see and read the IMEI of the phone displayed. If present, the operator (on which the phone is currently locked) logo should be clearly visible.
Insert, in the same phone, a SIM card which is not currently accepted by the phone.
Wait 5 seconds until we can clearly see and read the message displayed by the phone
Enter the code received by the server, VERY SLOWLY, and the keys being pressed (or touched) must be clearly seen in the video as the code is entered into the phone.
If you get an error message, wait 5 seconds so we can clearly see this message
By the way, make sure the video is correctly focused and the codes, messages, IMEI are all visible on the phone’s display. __________________
