Upgrading to V5.4.5 Build 170123 from V5.1.2 build 140116

[Roger]

Hello,

I have a DS-2CD2532F-IS S/N DS-2CD2532F-IS20XXXXXXCCWRXXXXXXXXX that I would like to upgrade. According to the readme file:
****** IMPORTANT - MUST READ and FOLLOW ******
Please check your current device firmware version before upgrade:
Scenario 1- If the version falls into the range from V5.2.0 build 140721 to V5.4.0 Build 160530, you need a 2-step ugrade process. Note, if the step was skipped, your device may fail to operate normally.
1) update to V5.4.41 build 170310 FIRST, reboot
2) update to v5.4.5 Build 170123, reboot

Scenario 2 - If your firmware is newer than V5.4.0 Build 160530, you can upgrade to V5.4.5 Build 170123 directly.
For HiDDNS user:
Please note, if you're using HiDDNS service connected directly to this IP camera, please upgrade to v5.4.41 build 170310 only. Starting v5.4.5 Build 170123, HiDDNS service is no longer supported but Hik-Connect.
Three questions:

1. Can I upgrade this camera using the US firmware.
2. Do I need to use the 2 step process or can I just use v5.4.5 Build 170123
3. Is there a published change list for different firmware versions?

Thanks in advance,
Roger

Yes you can use US firmware. no you must do 2 stage upgrade or you'll get reboots that you don't want.

Thanks for the reply. I tried today and I get an error message, but nothing in the logs. Anyway to diagnose or do I need to go from V5.1.2 build 140116 to another intermediate build first? If so, where would I find them?

I tried today and I get an error message, but nothing in the logs.

What was the actual error?
There are various possibilities, each with a different cause.
For example, the wrong firmware for your model.
What was the URL for the firmware download?

Found older versions on Hikvision Europe page and have made it through to the latest version.
