Hello everyone,
when I opened Armory Crate Gear ROG KERIS II ACE 1.0.2.0 today I got the message that a Firmware update is available.
This is the Versions that were shown when I got the Firmware Update notice:
I connected the Dongle with the Booster via the adapter and the cable to my PC. The
Mouse was connected via a cable too to the PC. I set the mouse to Wired Mode (middle position of the switch).
When I tried to update it said "Update failed. Please try again. (50)".
I then started the Dongle Update manually from the "C:\Program Files (x86)\ASUS\ArmouryDevice\Firmware\6862" Folder via the file "FW_Update_Tool_Unify_Dongle.exe". This went through but downgraded the Firmware to Version 6.00.23. And now it looks like that in Armory Crate Gear:
I still get the notice that a Firmware Upgrade is available but it still always fails with "Update failed. Please try again. (50)".
I tried:
I am always getting the same "Update failed. Please try again. (50)" error, sometimes the Progress Bar is starting for a second other times it immediately fails.
I would really like to be able to upgrade to the newest Firmware Version(s).
Thank you for reading and maybe you can help me.
