Hi @chouaib-ing,

Welcome to the community,

I am sorry to hear about the issues you are having, however, I can advise that the code you are getting is referring to the fact that the handset is a prototype device.

I suggest you speak with the place of purchase about this as at no stage should a prototype device be sold in any manner.

I am sorry for the inconvenience this may cause.

i want flash it manually but the screen is black

ii can't do anything

I am really sorry about this, but as it is a prototype device and not intended for public use there is no real solution I can provide. @uliwooly you may be able to supply alternative instructions?
