Dahua DSS7016-D-S2 boot problem!

Hi,

We have Dahua DSS7016-D-S2 with FW ver. V6.08.000.R.20170713.742753
From DahuaWiki site (DahuaWiki) I download FW ver 7. I was unpack it, login to our DSS and from Upgrade firmware option start with upgrade (file inside archive file: General_OverseasDSS7016S2_Eng_Basic_V1.001.0000001.2.R.20201211.BIN)

Everyting starts normal, and when it's done about 80% it stops
