Hi, I am new to the site and new to samsungs, I have had my Galaxy Ace 2 a few months now and am generally happy with it I have it set up for automatic updates, and just recently over the past couple weeks when doing the 'check for updates' it prompts that there is a software update available. I accept the download for it and it says 'downloading update package'. Once it has completed the download the phone flashes up a large pop up titled Software Update and asks to install the update. I press install and then it flashes up saying 'device will be rebooted'. Upon pressing ok, the phone switches off and reboots, turning back on with a screen appearing to be installing the update.... Now here is where the problem is.. Once it gets a certain point in the installation, it comes up with 'E-signature verification failed' and then aborts the installation and then the phone reboots as normal, and nothing has changed... Any idea what this software update is for and why it keeps failing? I have also tried doing the update through Kies Air, and through the pc software. This is really frustrating now!! PLEASE HELP!
