Can someone enlighten me what is the reason why I cannot upgrade my device? here's the screenshot. https://i.imgur.com/mPAWd0E.png I already hard reset it, I still cannot upgrade my firmware.

@john.awad sorry, I misread my version, I'm using v1 EU. the problem is there's an error when upgrading my firmware. It says Error Code : 4503

Hi ! When is the expected date that this firmware arrives to other versions? I'm using v4
