Hantek DSO1200 need flash dump SST39VF3201B or main PCB.
Hantek support not answer to my emails.

My Hantek DSO1200 dead after firmware upgrade:
1) Updating the firmware to 1.29 from a USB drive.
2) Firmware was broken by 70%, but the device continues to operate.
3) Turn off the device in a standard way (the button on the front panel).
4) After switching on ran ROLLBACK scale (firmware rollback).
5) The device after rollback went to reboot and shut down completely.
6) Now when press the on button produces beep and turns off after 5 seconds

(Display is dark all the time)
Sorry for my English. Russia here.
