Phone information is required before flashing
Download the flash (UPDATE) version higher than the one I tried and passed it in FastBoot mode
If it does not respond, the flash board must be loaded and passed in USB 1.0 mode

The wrong imai phone number will prompt you to open the network and re-edit the imei on the box ( chimera;sigma;nck; mrt octopus huawei; dtpro tool......)
Or download a firmware with a new version and re-flash the phone and try
