Door Entry Hikvision DS-KH9510-WTE1 firmware update?

[z0re]

Hi,

Does anyone know the process to firmware flash one of these devices? I have tried TFTP server on 192.168.1.128 and 192.0.0.128 and nothing happens on load up. I have connected via JST 4 pin to see if I can force update by pressing Ctrl + U on startup, but on this device it says press any key, which i do but the device keeps on loading without requesting digicap.dav file.
Any help much appreciated.

JST 4 pin to see if I can force update by pressing Ctrl + U on startup,

I've only ever stopped the boot process, did not reflash the firmware.

Are you pressing ctrl u or ctrl U?
