After process running time 98% contained the message "update failure"
then I try to check using Huawei Modem Unlocker and there is no IMEI number or blank IMEI.
So I writing IMEI and succeed. When I put the SIM card is no signal obtained too, so I try to restore nv file and the result ...ta..da..... now my modem E1550 is unlocked forever
