Thanks for your attention, but it seems that it isn’t a rollback problem because I have use the newer version firmware. Since my original version is 58.0.A.28.17 and the version I have flashed is 58.0.A.28.60

@munjeni and I have tried older version and found that the fault appearance is quite different.
If there is a rollback problem, the device will shows 'Your device is corrupt' instead of bootloops
I have try to use Xperia Companion to fix my devices, but Xperia Companion give me an 'temporarily unsupported devices' error.

One who reported #37 issue had boot loop instead of device corupted, and we have discovered (after getting bootloader boot log) that it is rollback protection isue (or maybe fw isue I don't know), but bootloader log clearly states about problem:

load_and_verify_vbmeta:657: ERROR: vbmeta_a: Image rollback index is less than the stored rollback index.

You can open thread on xda xperia 5 II forum and ask somebody. Newflsher apsolutly have nothing to do with it. Even no single error or warning trought newflasher, so no newflasher isue.
