VESC 75300 R2 R3 , latest FW ?

Hey

Using some 75300 since beginning of the year, i´m not able to update them to newer FW then the actually ones :

HW 75-300-R3 : FW 4.2
HW 75-300-R2 : FW 3.62

Using actually VESC TOOL 2.06

Having hard times setting up bigger motors,

Inrunner 5000gramm low KV (under 50) and 4000gramm Outrunners with 50kv

The R2 only works in sensored BLDC with the Inrunners (QS Motors 1000W)

With the Outrunner (APS120) the R2 just run in FOC, but having Overcurrent Faults

R3 works only in FOC with the Inrunner, Overcurrent Faults

I read that Ben says that the older FW have Problems on 75300 and he has alot fried ones already, dont wanna be next (-;

What can i do ?

Kind Regards

Jens
