Referring to my problem I encountered charging my mobile phone, I decided to follow the advice from the HTC support to hardreset my device. I really hate the idea, as I just finished installing the desired software and tweaking the mobile phone to my liking. Anyway. You have 2 options to hardreset your device (ALL your personal settings and your data will be deleted):

1) Menu: Settings – More – System: Delete Memory – enter 1234 as secutity code

2) Switch your phone off – press both volume buttons for a few seconds – release and power your device on by shortly pressing the power button – directly press both volume buttons again and wait until a warning text appears – release the buttons again and accept the text by pressing the volume-increase-button

While this is an easy thing to do, the result is irrevocable. A good planning therefore necessary, except you don’t care about your files.

I started this process by making a full backup of my phone using SPB Backup. You never know. Next step for me was the installation of MS Outlook (which came as a 60 day trial verson with the mobile phone), to sync my data with the computer. ( I’m using Windows Vista + ActiveSync.) I started Office and configured it without email access, since it isn’t necessary for this. After the configuration process (including a new start of the computer) you’re able to decide which files/information you would like to sync. I marked everything possible and synced it to my harddisk.

My last step before finally resetting the mobile phone was saving my messages with the programme SMSSync. Tips on where to download and how to use it are available here.
