Hi @John A
You should be able to find most old/legacy firmware at the Hikvision Download Portal
The latest version for your model is v5.5.800

Would you happen to know where we can find change logs for the firmware? I'm running 5.5.800 build 210628 on a few G3 cameras, and 5.5.801 build 211105 on a couple of other G3 cameras.
Right now, all of these are current on different parts of Hikvision's firmware websites:
| Firmware Version | Build Number | Approximate Creation Date | Camera Platform |
| 5.5.800 | 210628 | 2021-06-28 | G3 |
| 5.5.801 | 211105 | 2021-11-05 | G3 |
| 5.5.820 | 220520 | 2022-05-19 | G3 |
There also appears to be a 5.5.820 with release notes for the G3 now.
Edit: The firmware portal was updated and 5.5.820 has been removed from the G3 DS-2CD2X87G2 and G3 DS-2CD2XX6,2XX7G2 sections. As of December 22, 2022, the newest firmware is still 5.5.801.
5.5.820 now only exists in the DS-2CD3XX6G2,3XX7G2 sections. The change notes for it still say it will work for the DS-2CD2087G2-L and DS-2CD2347G2-L but my cameras will not upgrade from 5.5.801 to 5.5.820.

Hi @botts
We would recommend updating one of the cameras that is running v5.5.801 to the latest v5.5.820 and see how you get on.
If you run into any issues you can try and downgrade back to v5.5.801 and leave the rest of the cameras on v5.5.801, but if you don't have any issues with v5.5.820 you can update all the cameras to that version.
Unfortunately, Hikvision is patchy when it comes to publishing release notes/change logs. I can't find any notes for v800 or v801, but this is likely because v5.5.800 was a security patch that didn't do anything other than fix a reported security issue. Also, the G3 models have now been replaced by the (C) G5 firmware models, so the G3 firmware is unlikely to include any major updates going forward, it will on be bug fixes and security patches.

Unfortunately, when updating today, I was running into continual failures. I tried to redownload the firmware and noticed that
the firmware portal was updated and 5.5.820 has been removed from the G3 DS-2CD2X87G2 and G3 DS-2CD2XX6,2XX7G2 sections.
5.5.820 now only exists in the DS-2CD3XX6G2,3XX7G2 sections. The change notes for it still say it will work for the DS-2CD2087G2-L and DS-2CD2347G2-L but my cameras would not upgrade from 5.5.801 to 5.5.820.

Are we looking at different release notes? http://www.hikvisioneurope.com/uk/portal/portal/Product Firmware/Hikvision/03 Front Ends/IP Camera/G3 Platform(DS-2CD2XX6G2 3XX6G2 2X41G 2XX7G2 2XX6G0 XE6XXX)/DS-2CD3XX6G2,3XX7G2/5.5.820 build220520/Network CameraV5.5.820 Release Note.pdf
On the 5.5.820 release notes, the "Supported Product List" lists:
DS-2CD2087G2-L(U) and DS-2CD2047G2-L(U).
Which is clearly incorrect.

Hi @botts
Yes, which is why I said it looks like the release notes are incorrect, the v5.5.820 firmware is only found in the "DS-2CD3XX6G2,3XX7G2" download portal folder so I assume Hikvision support has made a mistake with the release notes and that "Supported Product List" should only include G3 3-series cameras.
I will pass the information on to Hikvision support for them to correct the release notes.

Hi @botts
I've shared the above information with Hikvision support and they have asked if you can provide screenshots of the Device Information page for both cameras and the upgrade failed page.
Don't post the screenshots here, please email them to us - info@use-ip.co.uk - and we will pass the information on to Hik support.

been doing some digging through my downloads.
this was the direct download URL for the .820 for the 2xxx non-(C) model.
https://hiknow-soft-bucket.s3.ap-so...files/202205/IPC_G3_EN_STD_5.5.820_220520.zip
the HIK HK website still uses the same link for the non (C) model.
