I recently did a version upgrade from 6.1.1 to 6.1.2. When I did the "switch version" and made the inactive partition the active partition, all the phones reverted back to a previous configuration. Is there a way to make these partitions sync so there is no loss of changes? Currently the active partition is 6.1.2 and the inactive is 6.1.1. Can I upgrade the inactive partition to 6.1.2 also? I have tried to do this and it tells me "No valid upgrade options were found".
no, they don't do any syncing. that's why you're instructed to do the switch after installing and warned that changes done after the upgrade won't be in the new version. it's completely expected to happen that way, you should have switched immediately or performed the upgrade when you could switch.
the only options are as i mentioned, to go back and perform the upgrade again, or simply redo all the changes on new version. whatever is easier for you.
if this helps, please rate
