Will I lose my data (mainly my SMSes) if I install this update?
//EDIT -> according to several forums, I will lose my data...
and I haven't found any solution to backup my SMSes - yeah -.-
Is there anything I should regard or be aware of before updating?
//EDIT -> I just tried updating my phone and don't know how. It boots in the bootloader (RGB-test with some data on the device, SPL, the SD card, ...) just fine but the RUU doesn't find it.
I'm trying to flash it from a Windows XP machine - is there anything I have to take care of before I can flash it?
Or is there a real step-by-step manual for total dummies (I've flashed my HTC Diamond several times before without problems and have got no clue, why the PC won't find my Mozart).
The update process cancels with a CONNECTION ERROR .
