It seems that all J2534 type devices (Such as DiCE) are being blocked from software downloads to SPA platform cars. It makes sense really. A “total upgrade” can be over 1GB in size which on a j2534 would could literally take 24hrs and its very likely to fail.
Even With VOE cables, updating 35 module can take hours.
On a Side note, VOE cables now in stock hahahah.
