I have an HTC Touch Pro2 that is OS Version 5.2.21889 and Rom Version 2.04.651.4 I did a rom update that said it would update, off the Sprint website here, to 6.5. I dont know if I need a different version first to take me to 6.0.0 or 6.1.0 or something first. Please help.
5.2.21889 is the OS build in relation to the CE Kernel version. In english, the technobabble. In actuality, Windows has been using that same version (5) since 2004 but updating it along the way. You already have 6.5.
