Hi form Barcelona!!

First of all thank you all people of this forum, you make possible the impossible for some of us.

Sorry if it was asked before, I saw something similar but a little bit different...

Go with it. My baby broke touchscreen. So, I decided to change it for myself and I received reference XC-PG0900-003-A1, because vendor says it's the same as 300-N3849M-A00-V1.0 MHS, wich was the original one. It was quite similar and install it.

Things are never easy. And now the touchscreen is rescaled. I explain: in landscape mode when my finger push X=0,Y=50, I see really touch in position X=450,Y=50. X axis has changed; portrait Y displaced.

So, I need your advice. I'm not a noob, I'm a super-noob.

I don't know if you need more data, please ask...

I tested a lot of calibration apk and they didn't work...

Question is: Is there a solution for this problem?? If yes, which is the best way to solve?? I think only way is flashing, but I'm not sure...

Thank you very much in advance.
