I'm not sure which end of the stick I have got hold of here so I hope someone can clarify things.
I understand the V 5.3 OTA upgrade between Feb 3rd & 5th was "on demand" or could just be left to the auto-update to sort out. During that time I could not upgrade V 1.0 UK (twin record) to 5.3 but when I flashed it back to V4.9 single record then it did upgrade ok.
My question is that now this upgrade window has closed what is supposed to happen? I believed that it was back to business as usual ie just the auto-update at 3:00 each night, my box is back to V4.9 single but it did NOT update to V5.3 last night. Why would this be??

My understanding is that it was only possible to upgrade to 5.3 OTA at the dates & times on the DTG schedule.
I already had 5.3 on my machine when purchased & I have been unable to install dual record.
