AMR. FINALLY! THIS we want! (but not the 2012-11-21 version if you have an EU model). I tried it twice, and both times T2 would not boot.
Needed to use the full backup to rescue the device twice in one day. With EU device, better use the previous AMR version, or, possibly the next one, if the issue is fixed.
Since I do not know what the issue is - I cannot fix it
So unless you would be able to provide some information about what happened it is unlikely to be fixed...
