Salahddine, since you can get into download and recovery modes, your best option now may be to do a complete stock restore via custom recovery. See the thread below for instructions. You may need to first flash custom recovery although I'd guess you probably have custom recovery installed already.
Download the relevant file posted in the link to your phone's internal SD card or to an external micro SDHC card and place in your phone. Boot into recovery mode and flash the zip. Hopefully, this should fix it.
