Hello to all
I need help
I updated the Dahua DH-NVR5432-4KS2 and then the NVR reset and after resetting the Dahua logo page for 1 minute and reset again
Old version: 3.210.0002.2
build data :2016-07-21
Upgrade to vrsion D H_NVR5XXX-4KS2_MULTILANG_V4.001.0000006.0.R.210208.BIN

I did the following to set up
1. Disconnect the hard drive cable
2. Detach the battery
3. Copy the update file to the root of the flash memory
