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,
Radek

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