Huawei P9 can't restore after DC-Unlocker unlock

[DekTri]

Hi, I have a P9 device, concretely EVA-TL00 model.
The owner unlock the bootloader via DC-Unlocker.

So, the problems are: the bootloader is unlocked but flashing TWRP give me a "Remote: image verification failed", the IMEI is 000000000000000 and only shows one IMEI when it's Dual-SIM. Some partitions are unable to flash too, giving a partition sizing error via fastboot.
Updating from dload didn't work.

Could be that it hasn't unlock good or give her some error during the unlock?

How can I put this phone working well again if I don't have any backup?

Sorry for my poor English.

It seems that you need to repair the phone info with HCU: http://hcu-client.com/huawei-phone-r...s-empty-board/
Certainly something has been messed up. Is FRP locked?

The OEM Unlock button dissapeared from the settings and in Bootloader mode doesn't appear the FRP status, from fastboot i am unable to see too.

In your place I would add the information with HCU Client and flash board software, firmware and customization with DC Phoenix. I just had a P9 Lite here, in similar condition, and all could be restored.
