Updating to CM11 - (Status 7) Installation aborted (i9300) I'm trying to install CM11 onto my Samsung Galaxy S3 (i9300) so I can have the new Google Camera and Chrome Remote Desktop apps.
I tried to install initially via the usual update menu, but got an error and it went to ClockworkRecovery Mod. After much messing around, I downloaded this zip and put it onto an SD card and tried to install it using CWM but I get the following error:

Error in cm-11-2014005-SNAPSHOT-M5-i9300.zip (Status 7) Installation
aborted

Any ideas please? It sucks being without a phone, and I don't want to wipe everything and start again if I can help it since I'm pretty sure I have things on there that aren't backed up (that'll be my first job when I get this working again!)
Thanks :)
A quick google search turned up this.
