Need to dump sms messages from xiaomi with damaged display.

Mar 22, 2013
Hi all ! Last night the display on my Xiaomi MI2 was damaged, the case is that 3 sms messages beep'ed in before I could move the sim card to another phone. It is cricial to me to be able to dump the messages to a computer in order to read them. The question is how ? Been googling around today but no real good answers neither to where sms'es are stored, nor in what file or database. I'm on version 3.5.3.
I am able to read the file system on my pc with usb cable, but programs like MyPhone explorer won't connect to the phone, so reading sms this way doesn't work. Any help anyone please ?
