Hi,

I've just bought pair of UBOOM L and want to downgrade them from 0.50 to 0.4.8.

Everything is installed and attached correctly, while starting application 2.0.05 is showing following error and stuck from there:

2023-10-13 15:53:44 Application Startup...
2023-10-13 15:54:38 DEVICE1:102 RUN_HWSC_FAILED("None" in fwsp.BaseFirmwareOP.HWSC(fwsp.py, line 438))
2023-10-13 15:54:38 Device 1:102 failed: RUN_HWSC_FAILED, took 1 seconds (15%)

What to do to complete firmware update?

Kind regards
