@Alb: Official updates are mostly delta updates, not full firmware image dumps => no OTA downgrade (at least with the 'usual' Update 5.1.0 update file from Amazon... Actually building a proper OTA 5.1.1 -> 5.1.0 'update' would be a pretty convoluted process, and it might have to lie a bit about what it does, because I'm not sure the OTA updater will let an update targeting a build revision lesser than the source revision run...).
