I had same issue. NV data is damaged or missing. I solved by flashing NV partitions for corresponding model from support (press download on DC Phoenix and search for nv partitions for your model)

After write nv partition you still have to repair IMEI using HCU. This time you won't have wrong backup file error

Your NV partitions is not written. There is no line saying NV data found and Read NV Failed. You need to use loader in DC to boot into fastbokt first, then flash NV partitions when phone is in fastboot mode (select don't reboot). And repair IMEI straight (without rebooting)
