You must be think what the hell you still using this phone :P I would say that this phone is my dad's phone and now he is not in this world. So I still dont give this phone to anyone. I want to keep this phone working. But today I got white screen and it was the firmware problem and I used the XS++ v2.2 to flash the the firmware which was downloaded from online but I need some new skin for walkman player so I downloaded the window media player skin for my player but when I copy the skin to my phone and even than the skin did not change. I used the following tools for flashing and firmware and skin for my phone.

XS++ v2.2 as flashing tool.
I downloaded the firmware from

And after flashing I used JDFlasher to copy the walkman skin (the procedure is common and I will require more time to tell what I did here but still what I had done was correct when watching this

)
I copied the skin to .../mp/skin folder by watching the above video (skin folder was not there by default so I created it and copied all the skin files which were in .png format)
And after that I press f10 to exit in JDFlasher. And restart the phone. But the skin had not changed.

What I am thinking now if I missed some patch or anything that is not making the walkman skin to change.
