No, never got it to work.
That's unfortunate, but I think it is a user issue (i.e. you are missing a step), just like it was for me the first time where I couldn't get it to work.
If you want to post your step by step workflow I am willing to help!

I upgraded LNB8105X to DH_IPC-HX2X3X-Rhea_MultiLang_NP_Stream2_V2.800.0000016.0.R.200605.bin via TFTP, and then was able to upgrade via GUI to DH_IPC-HX2X3X-Rhea_MultiLang_NP_Stream2_V2.800.0000018.0.R.210707.bin. I did it recently, so not sure how reliable it will be. After upgrade IVS became available, which seems to work fine so far.
I noticed there is a new firmware here: Index of /Firmware/Kamery -IP- stałopozycyjne/LITE265

>DH_IPC-HX2X3X-Rhea_MultiLang_PN_Stream2_V2.800.0000026.0.R.220822.bin, checked the check.img file and looks like this is on the list.
Does Dahua have any release notes on firmware, where would one find something like that?

How is 210707 working, still stable???

Cheers and thanks!

Success!!
Thank you for the instructions TXT file @val-ipcam , and also I appreciate you responding, as I was very frustrated and wasted a lot of time.
@exarkun see below

1) I missed the part about having the 2nd IP (192.168.1.1) - my mistake here!!!

2) For me there was also the problem of the TFTP that was linked in this topic, this was not working for me. I instead used TFTPServerSP V1.6x (which I've used in the past to get OWRT FW onto some Meraki MR42s). This worked and it's more flexible options wise; I edited the INI file to listen on ALL IPs, although I think you can keep your laptop/desktop connected to your regular network and then configure the INI file to only listen to 192.168.254.254 and 192.168.1.1 (I'm guessing here, but should work).

3) It complained there was not success.txt file at the end after grabbing all the IMG files (I extracted ALL the IMG files from the BIN into the root folder of the TFTP server). Well other than grabbing the IMG files and this complaint at the end, it wasn't very verbose, so I didn't know if I should leave it, or reboot it... I left it, saw there was a green light at the front and when I picked it up the alarm went off AHAHAH, thankfully I was in the basement and didn't wake up anyone.

It kept the same login/password as I had before, but instead a nice DAHUA screen, with working live feed (without downloading some stupid plugins). Info still says it's a LNB8211x, but the rest, as you see below.

I used a little 8 port hub I bought more than a decade ago, which I kept as it's very handy for such things. Laptop port plugged into it, camera plugged into it, and I used a 12v DC power supply for the camera (again, from Meraki APs).

Cheers!

What is TFTPServerSP V1.6x ? I'm not finding it with a google search...

Decided to give this another try and following @val-ipcam's previous comment and using TFTPD64 mentioned above, I was just able to successfully flash Dahua firmware into my Lorex LNB8105X using the 2020 firmware. Previously I tried it plugging it directly to a switch with my PC plugged in same switch and it never recognizes the TFTP server. Today, I'm using POE injector plugged into the PC and with tftpd64 running, I did a reset on the camera while it's plugged in and as soon as it restarted, it starts seeing the tftp server and flash went as expected. Thanks for everyone who gave their comments and what they did to get this going. It's been super helpful for those of us who has Lorex cam and wanted to give this a try.

On that note, which firmware are you using for this Lorex equilavent to ipc-hfw1831c-pir-4k? Is the one posted by Andy 2021 stable or are you sticking with the 2020 one?

I'm using DH_IPC-HX2X3X-Rhea_MultiLang_PN_Stream2_V2.800.0000026.0.R.220822 with no issues.

@exarkun, is that firmware working well for you? I was looking at previous thread to find the download links, but came across others reporting missing "Audio Linkage" with this 220822 firmware version? Currently, I'm on the 210707 firmware with the ipc-hfw1831c-pir and unless I have overlooked something, one flaw I notice is there's no way just to enable PIR detection with light only. If PIR detection is enabled, it would trigger both the light and siren. Are you able to enable PIR with light-only without turn on the siren with this 220822 firmware?

I had shared directions for this here. At least it worked for me...

For those that is using the latest 2020822 firmware with this camera and would like to use the PIR for onvif trigger with Blue Iris and do not want to turn on the siren when PIR detects something, you can use the http api command below to do that. This is essentially disabling the "Audio Linkage" setting that's no longer visible using the Web GUI browser on this later firmware. Be sure to replace the x.x.x.x with the actual IP address of your camera.

At initial attempt using the web browser, it should prompt you to enter to your username and password. Afterward, it should return status "OK" if it's successful. You can check whether or not the setting is effective by running the first link below to review all the Alarm config parameters and look at the "AlarmBellEnable" and "VoiceEnable" settings specifically. From my testing, the setting will stick even after rebooting the camera and AS LONG AS YOU DON'T change with the Lighting configuration (Flicker vs Normally on setting and how long it stays on). If you change the lighting configuration, then you will need to rerun the commands below to turn on the audio linkage with PIR alarm.

#Review Alarm configuration

#Turn off siren sound when PIR is triggered

Also, if you would to setup Blue Iris to manually turn on the Light or Siren upon a trigger event or some automation you custom setup, you can use the http command below to do that.

#Turn on/off alarm light

#Turn on/off Siren
