Downgrade Form V6 5.5.1 To 4.12.5 Final V5

Hi,

I tried MIUI v6 on my Mi2s, which is currently updated to 5.5.1 but I have some issues during calls and calendar is not working. So, I want to downgrade to final v5. Can I just download this aries ROM, save it to phone and 'update' with updater app or with MI recovery. Is there something else what must be done prior flashing?

You cant downgrade directly.
You got to install a oficial miui V5 rom through MiTools and select wipe all.
Then you should use xiaomi.eu_multi_aries_4.12.5_v5-4.1.zip. It´s the final V5 ROM.

HI, thanks for your reply.

But you must explain it more to me, where can I find MiTools?

edit:
I googled that MiTool is WIN (in my case) application. Now, how to install official V5?

You should reseach a little, for your own benefit.
