this is crap, someone just bought latest MSO5202D model from Hantek and installed latest firmware from Hantek website. ... and of course the MSO is now bricked !!!
I just did this to an MSO5102D. It's on it's way back to China. Not happy
... and i got solution from Hantek. In principle all you needed is set of files which were repalced as you installed the wrong firmware.
For you maybe (well, let's hope this was the first and last time you picked up "wrong" firmware) not anymore important, but in case someone else need to restore latest MSO model (note - with S/N > 15000 and fw 3.x installed) then
- download this archive:
http://www.mikrocontroller.net/attachment/189050/system.zip- unzip it to usb flash drive
- connect MSO UART port to PC (over 3.3V UART <-> USB adapter), here the pinout
- boot MSO, run on PC your fav. terminal app (115200, 8n1)
- enter the MSO shell, kill the watchdog by executing "killall dsod" (the best, do it multiple times, we don't need it now!)
- insert usb flash drive into MSOs front USB port
- copy/run following on MSO
cp /mnt/udisk/dso/app/dsod /dso/app/dsod
cp /mnt/udisk/dso/drivers/tq2416_backlight.ko /dso/drivers/tq2416_backlight.ko
cp /mnt/udisk/etc/init.d/rcS /etc/init.d/rcS
cp /mnt/udisk/OurLanguages/English.lan /OurLanguages/English.lan
cp /mnt/udisk/dso_bin /dso_bin
chmod 777 /dso/app/dsod
chmod 777 /dso_bin
chmod 777 /etc/init.d/rcS
sync
sync
rm /dso.exe
- test the firmware!, go back to / (cd / ), and execute /dso_bin
If everything works, you can power off MSO and disconnect the UART from PC.
