Is it only XRFTEST and XPRODDONE that gives the error? Then I'm afraid that XPRODDONE has been enabled earlier. Please verify.

If this is the case, then there isn't much I can do I'm afraid. 

Kind regards,
Øyvind

thank you reply,

Can these functions be restored by re-downloading the modem after erasing?

No, this locks the current modem FW. No way of changing this other than starting with a new device I'm afraid. 

Kind regards,
