Thank you for the answer
The download completed on the third try and the rest of the installation went smooth !
I only have one bug now, I cannot lock the phone via PIN or fingerprint. Every time I try ti set it up i end up with a message that state “screen lock was already change. Please try with the new screen lock”
Does anybody has already experience this ?
Maybe it’s not the right topic to ask sorry about that
