I want to upgrade my HTC Touch HD GSM Windows OS from 6.1 to 6.5.
What is 1.56.OliNex simple comprehensive English?
what is the difference between upgrading through HSPL and USPL?
I don't really know the meaning and the difference between HSPL and USPL, and which one is recommended and less risky?
I went to xda-developers.com and couldn't comprehend there well.
