First of all, i erased the modems with the phone rooted using adb commands (erased modemst1 and st2 on the their partitions).
Unroot the phone to open the diagg port typing on dialer *#*#13491#*#*.
Used the QFIL program to restore the phone using a qcn archive who send me a user which cotains their imes and baseband configuration.
Reboot and open the diagg port again.
Used the WriteDualIMEI_W_G_eMMC to rewrite my owns imeis.
Reboot and all wherw fine.
I ll create a qcn with fakes imeis to restore your baseband if you need. Then, you only have to rewrite the imeis with the WriteDualIMEI_W_G_eMMC program.
You will find the programs searching in google easly.
Good luck
