If you have used flashtool and didn't untick flash baseband,this might be the issue.

@Thommo If he flashes a correct firmware for his device, will he get the baseband and IMEI back? If yes,see this:

thank you very much so i am gonna just wait for his answer !

[Thommo]

Are you sure you flashed the correct firmware for your device and country or did you flash something else as the only time this happens is flashing the wrong firmware or you have tried to modify a firmware like deodexing and flashing via a recovery program like Teamwin or Clockwork mod

thank you for your answer

No , i am not sure about that , but i didn't modify or something can you please tell which frimware to download , i can afford any information you need

[Thommo]

Do you know what firmware should be on and do you have the C6903 device and not another variant

[Nokk]

Thank you for your answer;

i have a C6903 and i am in morocco and i don't know what firmware to download

You have to download Generic-MENA (Middle East and North Africa) Firmware but you can rarely find a one so if you don't go for GENRIC-IN (India) or any FTF with GENRIC but you won't get arabic language anymore... and make sure to download the ftf which is for C6903.
