Same here, also in the UK.
Some observations.
The new game controller mapper is excellent so far. I just created a profile for Epic Citadel and it works well. I'm using a Moga Pro Controller in B mode. We should now be able to use controllers for games that don't natively support them.
The bug where unmounting an external hard drive through settings/storage would also partially unmount the microSD card seems to have gone, though I've only tried it once.
The bug when using an external keyboard via Bluetooth or USB OTG where the 'auto correct', 'double tap space bar' and 'auto capitalise' options in the external hardware keyboard section do not work, remains. Shame.
The problems with HDMI out also remain, where video output that was smooth under the original firmware (4.2?) has micro stutters. No idea why, my movies aren't even HD. Also, the ability to zoom in in MX Player to force HDMI output to fill the edges of the TV screen that was possible with the original firmware (which was very useful indeed) has not made a return in this update.

Hope it will work - stuck at 1/4 for 20min now.

Same thing happened to me then it suddenly completed. I had a bit of a panic about it ?
