Few weeks ago my PC stopped to recognize my kindle, meanwhile it charging w/o any problems. After short investigations i found that 2 middle pins (D- D+) of usb jack lost connection with pcb. So i decided to soldering them back. Suddenly there was an accident that destroyed part of the chip (body of that chip were badly damaged) under U1102 sign. Now i'm looking for that chip to replace.
Tomorrow i will check serial number of the kindle to find out model name.

Did you try a different USB cable?
What you describe is a "power only" USB cable.
That model is too new for you to have worn out the connector.
They are rated at over 50,000 insertions.
You haven't done that, even if you spent every minute connecting and dis-connecting the USB cable since you bought the Kindle.
You can find your device's serial number listed on your Amazon, Kindle Account page(s) - no need to put it back together.
What you have is not a KT2 -
The KT2 uses a surface mount USB connector, not that mid-line mount USB connector.
My bad, I was looking at the wrong picture in my picture gallery.
I understand you want the part number of the chip.
Let me re-word my earlier answer:
I do not know, you will have to look at yours using an intense, transversal, light.
Since you found the photo in this thread -
then you may have a PW-2, which I do not have.
(There are some PW-2 photos in this KT2 thread.)
OR
That is a different board revision than the one I have.
= = = =
Destroying the plastic, molded, chip package does nothing to the chip -
Unless you mean you have exposed the actual silicon chip and its bonded wire connections.
Even then, you probably haven't done any damage to the chip unless you also destroyed the bonded wire connections.
But your attached picture, under magnification, does seem to show that you have lifted the traces between the connector and the chip.
I suggest that you find yourself access to a hot air, smd re-work station -
remove both the chip and the connector (using a quality solder removing paste) -
clean the board -
repair the pads and traces -
then replace the parts -
Note: both the connector and the chip look re-usable.
