your camera is an SA (per the updateSerial=IPC-HFW3841EP-SA you posted). just because the -AS exists as a Dahua doesn't mean it's the same...
(then again, they may well be close enuf that the same FW's work)
I would try the firmware with the right HWID in it (as i linked to) that most closely matches the date of your current FW.
In any case, you may need to use TFTP to get it on there... once on the DH fw, you should be able to upgrade via web GUI.
