No. It doesn't have an A on it sucmnsee.
I took the front panel board out & had a probe around. Turns out there was a surface mount capacitor across the IR sensor's VCC supply that had gone short circuit. I've got no idea what it's value should be, so replaced it with a 1nF disc ceramic capacitor.
All working fine now.
Still wondering why johnner09's image doesn't load. Looking at his folder, it has BackupSuit.log, imageversion, noforce, kernel.bin & rootfs.bin.
The folder from cloud-ibox.net has force, imageversion, kernel.bin, rootfs.bin & splash.bin.
Could it have something to do with the force/noforce file? I notice that it says "rename this file to 'force' to force an update without confirmation". Do you know what kind of confimation it needs? Is it done to stop the image from flashing again if you leave the USB stick in the box?
