Lorex E891AB (aka IPC-HFW1841EN-PV)

right. clearly this was branched off from the 1831E code line, but may have other code (for the white LED's and two-way audio for example) the base unit doesn't support. IE, this does NOT mean we now have Dahua-branded/featured FW for these Lorex units, just that we can recover the stock Lorex fw if needed as we carefully explore other options... :-)
 
Ya, I was able to get the stock loaded back onto it just fine. Honestly the biggest thing I was hoping for was a modern frigging web interface. I may play with this a bit more as I get time, but it's obviously doing a hardware check and bombing out when it doesn't find what it wants.


Anyone else heading down this path, just so you don't have to go searching in other forums, these are the commands you need to issue for the firmware update with lorex:

run dr
run dk
run du
run dw
run dp
run dc
run pd

Heads up: this firmware is not appropriate to properly recover LNB9232s (HFW1831EN) units.
My unit no longer supports 30FPS, maxing out at 15FPS until 3MP resolution is selected.

The "08" version of the firmware is apparently varporware.
 
This is customized firmware.
Unable to change to Dahua firmware.

Use Dahua DH7200 processor + OS08A20
