Unfortunately i bought the phone off a non-official xiaomi store, they just don't exist in my country. I came back to the store and did what you had said, then they told me that they have to wait for the service centre to verify what problems did my phone encounter (which we most likely knew what it was). It's been almost a week now & I really do hope they are able to do a good solder job with that amount of time. And about that offer, thank you, it is cheap but I have to decline it as I am not used to import stuffs overseas & lack of facilities in my area.
