Upgrading from old firmware on D315

Hi,


I have some D315 handsets that are running the 3CX 8.7.5.28 firmware.


I'm working on one of these to get it up to the current 10.1.54.16 release.


I manually installed 8.9.3.80 which it took and then it subsequently automatically went to 8.9.3.96


Since then I've tried to manually take it to 10.1.54.16, 10.1.39.11 and 10.1.33.33 but on each attempt, the firmware takes, the phone boots into it once then automatically starts the upgrade process again which seems to fail and the phone then reverts to 8.9.3.96. 

So, how can I get it beyond 8.9.3.96 and up to 10.1.54.16?

I can see you've raised a ticket (it was originally close because you've selected the old 3xx series, but I've changed that on our side) on our helpdesk about this, and we came back already, so we'll continue to investigate this in the ticket directly.
