Huawei P9 Lite VNS-L23 doesn't flash

[Feadim]

Hi! I bought a 3 day license to revive my phone after a brick (out of nowere, after a reboot, the phone get stuck in a bootloop and doesn't enter recovery either). It enter fastboot, so I decide to try DC Phoenix. After starting the flash and the phone is rebooter to upgrade mode it get stuck in Huawei logo. Then I try manualy to get the upgrade mode, but it enter again in a bootloop. Now i can get to erecovery, but nothing change after rebooting it enter again in bootloop.
Any clues?

PD edit: The phone locked after flashing the board. That flashing wasn't complete. Boot, fastboot and another partitions cannot be flashed.

Best chance to repair it was to attempt flash with exact same firmware that runs inside the device, but if you have flashed board already, even if it was an only partial success, then now can only attempt other board softwares for VNS- that are available, customization such as -L23 -21 doesn't matter, so any VNS board software. If any of them flashes fully and the phone boots into the factory home screen then it is a good sign that phone can be fixed without the replacement of the mainboard.

Sadly neither of the VNS-L2X boards finish a full flash, all of them fail to flash boot and some other partitions. DC Phoenix was my last hope to save the phone, thanks anyway.
