Goes in parts please.
The first error "FLASH: wrong header" is because the file downloaded is damaged. Try to download again.
The second error: "CSLOADER: card timeout" is because the software can't start the loader to finalize the phone.
The third error: "configuration error" is because the phone is not finalized.
Download again the Wotan Client (save in another location) and download again all the firmwares and try again.
Thanks
Regards!
