Flashing and repartitioning Xiaomi MI2S running MIUI6

I can boot in to bootloader with miui v6.
Then I can do

Code:

---

fastboot oem unlock

---

And now I can flash custom recoveries with fastboot command

Code:

---

fastboot flash recovery recovery.img

---

Now you have a working custom recovery. Miui v6 will replace it if you update the ROM, so no problem. Now you can flash some rom (for example CM12.1 by M1cha)

For repartition my Mi2S I used this guide by M1cha and it works fine.
