Unavailable to activate

Hey apple customer support!

I'm facing issue, last day I did factory reset to my iphone X.

After that the blu ⚠️ caution appear ( unable to activate) - so install itunes and download the update firmware file, and both trying update and restore.

But after this flashing, the red ⚠️ caution appear, I'm unable to active my iphone x please give me solution or try to fix this ASAP

Warm regards:

Afaq
