Xiaomi Router 3G flashing from Padavan to OpenWrt

hi everyone,

I have install Padavan in my router mi 3G but now I want to change.
I was checking the guide to install openWrt but I notice that partitions don’t align with the guide.

My partitions right now:
mtd0: 00080000 00020000 "Bootloader"
mtd1: 00080000 00020000 "BootEnv"
mtd2: 00040000 00020000 "Factory"
mtd3: 00040000 00020000 "crash"
mtd4: 00040000 00020000 "crash_syslog"
mtd5: 00040000 00020000 "reserved0"
mtd6: 00400000 00020000 "kernel0"
mtd7: 00140000 00020000 "Kernel"
mtd8: 012c0000 00020000 "RootFS"
mtd9: 00100000 00020000 "Config"
mtd10: 00400000 00020000 "Storage"
mtd11: 06080000 00020000 "RWFS"
mtd12: 01400000 00020000 "Firmware_Stub"

Can flash from padavan to openwrt? Or do I have to flash to stock first ?
