I would like to help you with this issue.
But your phone run the YUK version, and the versoin is old V72 version.
As I know, the v72 version can't suppor the SHA256. The latet YUK V80 version maybe support it.
And I can't send the YUK version to you. Sugget that you can contact with the YUK distributor for V80 version to do a test.

We've now been without phones for over a week. UK support say it is with 'R&D' and that they are continually chasing but nothing's happening. The support we are getting is woeful. If this had been a customer's system we would be in serious trouble now, but it's still very embarrassing for us.

We are using SHA1, but we have also tried upgrading the firmware to the new version which supports SHA256, but the problem still persists.

What do we need to do to get technical support? Once again we are feeling let down by inadequate help on the rare occasion that we need to ask for it.
