Asking in an old thread a complete different question ... meh.
Openwrt for AX3600 will create only one big partition for openwrt, no dualboot-partitions;
But if you go back to the original firmware everything is back to OOB. Use the debricking steps in the wiki or the xiaomi MIWIFIRepairTool see MIWIFIRepairTool
