Thanks for posting. This eliminates one of the negatives about the receiver for me since I have no problem doing the updates.

I was successful in updating my AR5700D. The only update I needed was the Panel to 508A. Given how AOR numbers their versions, this is a update from August 2025. I also updated DigiDec as it says to do. I think you do the DigiDec update each time because the updater can not get the version. It is too bad there is no updated firmware version list yet.

I initially had problems because the Null Modem (cross) cable did not work. A straight female-female cable did work. I also discovered a real hardware serial port will not work, likely due to baud rate limitations.

I used a IOGear USB GUC232A Serial Dongle (a rebadged ATEN UC232A). If the serial number is Z3 or Z8 and the third character is a letter, then it has a supported Prolific chip (post-2012). The Windows 10/11 driver I use is v1.1.102 for the ATEN.

When I pressed the Panel button I got a pop-up window with further steps. They made updating easier than the AR-Alpha as only a small panel on the bottom of the receiver is removed to change the dip switches. I followed the procedure without any problems.

I went through the procedure for the DigiDec update using the I/Q Out. The I/Q driver has to be installed. Again another pop-up windows was display when I pressed DigiDec. It does take a while and several OPEN ERROR messages occurred for some reason. The process continued until it displayed success after about 10 minutes. I turned off the receiver by the main power switch and turned it back on. Everything still works and the version display reflects the new firmware. My receiver now has:
Main_403AR D4NC P508A

straight rs232, not using null-modem.

The possibility of updating the receiver yourself and making it evolve is an advantage, which was not possible with the 5700D. On the other hand, Aor remains behind compared to ICOM on the software plan: the hardware is of very good quality, but the software monitoring presents limits.

This update breaks audio playback on the receiver from the SD card, playback is now so muffled and distorted it is unusable. If you use that don't load this update.

I wait to update my 5700d.... Method is not well explained and you have bugs... AOR must clarify and put valid upgrade...
