Juniper SRX downgrade error

При попытке откатиться с версии Junos 15.1x49-D60 на 15.1x49-D50 в режиме VC, node0 завила в процессе инсталяции и висела, пока устройство не было перезагружено руками.
После перезагрузки, устройство загружалось со прежней версией ОС а при попытке сделать downgrade получалась следующая ошибка:
