Hi, hope someone can help. I am sick of waiting for TMobile to reissue their OTA update to 126.96.36.199 so wanted to install it myself. Am desperate to install it as have read in couple of places on XDA forums that it increases the media volume which is a big issue on my device (yes, yes I know some of you get blown away by yours but trust me I'm not deaf or stupid, it's just ridiculously quiet). Anyway I have managed to download a zip of the update but am confused as to what to do next. Any help would be greatly appreciated, Thank you.
