DSO150 : Reverting to vanilla firmware

You can revert to Jyetech firmware easily, assuming you have a STLink v2 and soldered the SWD connector
1- Download the firmware from jyetech, unzip it
2- Power the board through the SWD connector and DONT SWITCH IT ON

NEVER POWER BOTH VIA SWD AND VIA THE BOARD AT THE SAME TIME

3- st-flash --format ihex write 113-15001-064.hex

since we dont touch at all the content of the eeprom chip, you shouldnt have issue with the serial number ( untested).
