Default [Q] Huawei ascend G740: IMEI=0

hi guys

I have a huawei ascend G740, which mistakenly updated by a Update.appfor orange yumo

although theoretically is the same cell, was updated correctly, but I get off the IMEI, leaving it at 0

I tried a method I saw the G300 ascend, but does not work in projectmenu trying to open ports, I asked for a password, but 0 does not work, tells me "invalid input"

I'm blocked at this point, know her other method to change the IMEI?
