BLA-AL00 brush factory firmware error original version 8.1.0.350

[xiaoshen]

Because the version upgraded to 8.1.0.350, the mobile phone was originally BLA-L29. After changing to BLA-AL00, the mobile phone has NCK, because it does not support downgrading. Then I want to solve this problem by burning factory firmware.

The problem now is that DC Phoenix 0.0.0.63 has been stuck in, Writing bootloader...

Error writing Bootloader

It means that bootloader in the file does not fit your device.

My current mobile phone can't be turned on. Can there be other ways to fix it? For example, is there any file that IDT burns? I want to give it a try, thank you very much for your prompt reply.
