Hikvision DS-2CD2142F-IS (R6 Series) 5.2.5->5.4.5

[bugaboo6av2]

HI, i have DS-2CD2142F-IS with firmware V5.2.5 build 141201. The Serial N. contain "CH" but the interface language is english. I would like to update to a newer firmware version starting from v5.3.0 (Then v5.4.0->v5.4.5). I can't find the firmware v5.3.0 in DOWNLOAD PORTAL. I tried to update to v.5.3.3 but I bricked the camera so i reinstalled v5.2.5 using tftp (and now the camera is up and running). Can someone pls help me?

I suspect that's going to happen with an non-CN firmware for your CCCH camera.
I don't believe I've seen any 5.3.0 R6 firmware.
