Apology in advance in case of repeated post.
Here are info on my DSO Quad out of the box. Hardware Ver V2.70, DS203 Mini DSO SYS Ver 1.52. DS203 Mini DSO APP (Plus A1) Ver 1.03.
I downloaded the attached Upgrade files and the two files inside are FPGA_281.ADR and FPGA_281.bin .
At first, I connect my DSO Quad to Macbook, press and hold ( >|| ) button and power on.
I got the follow message :
Device Firmware Upgrade V3.11C. Please Copy Hex or Bin File to The DFU Virtual USB Disk.
At that time, i am sure i saw 2MB of free space on DFU Virtual disk so i copy and paste both the .ADr and .bin unaware that i am not suppose to copy and past two files at the same time.
Problem starts from there. Nothing happen. No changes on my firmware or anything.
So I try to re-connect DSO Quad to PC and try to do the bootloader again (>||) . This time, on Macbook, i can see the DFU Virtual disk is connecting and also disconnecting at the same time.
I just can’t seem to open the Disk anymore. I tried agin upon my windows 8.1 . Even worse, my explorer freeze and need to hard restart my PC itself.
Please guide my thought how can i go about this problem. I know nothing about DSO Quad. Very new to this. Can’t seem to find the factory reset button or anything at all!
