looking for SIP firmware for WL2

[jarmac]

Hello

I'm looking for upgrade firmware for OpenStage WL2 from HFA to SIP
Siemens was closed this software and this is not accessible right now
(also with service support - not nice ):

so if somebody has :
prep70_39.img
swup_70-000-052.img

I will be grateful
regards

Only WL3 available.
Try Ascom ?
