      You need to flash nv backup. May try one of availables on support area. You may review files here: https://www.dc-unlocker.com/firmware-catalog in filter field enter "backup" and look for file matching your phone's cpu. You should flash it on dc-phoenix in testpoint mode.

        Thanks for answering.I did flash all these 3 versions of nv-backup but still it showed these error logs.

        When I used hcu client and dc-phoenix in testpint mode, the software always says ‘looking for fastboot mode’ message box and just like this:'2023-02-01 04:59:20.442 Waiting for device REMOVAL/INSERTION...' which is very diffrent from offical tutorials and Video tutorial​.Is it normal?

        I guess maybe it is the downgrade method did not change the nv patition? My phone was in Harmony OS and I downgrade it to EMUI9.1 by HiSuite.Proxy.V3.3.0.

        May be I should try to flash my phone in 1.0 com mode the original board 9.1 firmware.

          You may try to, though the problem might be more serious. Just after flashing board, you need to flash stock rom as well, otherwise bootloader unlock won't work.
