Hello,

This morning I was performing a software update on a vehicle using ISTA using a BMW i3 120 2021, VIN: WBY8P210107J99347. Everything was fine except for the programming of the HU-H unit where it showed "programming aborted unit" and failed to revive said unit even after repeated attempts.

Everything was working fine before.

Please, how should I ideally proceed now?

I have AutoHex II and HexProg available.

Thank you.

Regards,

HU flashing is risky even in ISTA. Please proceed to do indiv programming using Autohex and check if the programming ok.
