[AC Question]

i have clicked on factory data reset button by mistake on my yu yureka phone.

accidentelly I have clicked on factory data reset button on my yu yureka phone and all my data is gone. I need it. there was very important data and everything was in my internal memory. but I am not able to use any recovery tool because as I connect my device to pc it reads as MTP device not any external storage device.
I need help because as days are passing my data will be more difficult to recover.
