I have been trying to update my HTC Desire HD that is unlocked from the UK. Every time I try to update the operating system file the file will download and then it says the file is corrupt. I can not find a way around this. I would like to be able to update to the Froyo 2.2 operating system. Does anyone have any suggestions for me to try? I am ready to junk this stupid phone. Any help will greatly be appreciated!!!
