Suito-T stuck after FW update

[thomas.bandelier]

STart of the winter season, so I wanted to bring my Suito back to operation today !
Upgrado app proposed me to update it to version 210, which I did.
At the end I had a failure message. The Suito stayed in the "blinking blue led" state forever.
Restarted the Suito and same - seems like I'm stuck in the DFU mode (I can see a DfuTarg device when scanning BT from my phone)

Is there any known way to recover the SUito in this case or will I have to send it to Suito for reflash ?
I created a ticket for support in parallel, but in the mean time if there's something known to do to recover , glad to learn it !
