Following the instructions by the support guys I'm opening this post.
I have already explained the problem at the link above.
An e-mail was also sent to Mr Semerkono Awesamu explaining the whole problem we're facing and the need of solution because of a delivery of 4000 devices.
The problem can be seen here at those pictures.

Thanks once again for the attention you guys from support are always giving to us and hope to hear from you ASAP.
Best regards.
