Tech support from pros:
You have to contact your reseller.
They will send back your programmer to the factory.
For me, obdexpress.co.uk is a good man of his word to trust in.
Items from the site are with relief. They did help me with the issue.
It seems they replaced or reprogrammed this ST32 microcontroller
FYI, some Chinese sellers are lazy in this case
In our case, the first time the reseller sent back the programmer with the following message “everything fine” of course it’s still in non-working condition because they are not sent the programmer to the factory.
