Just to add, thank's ixtab. I wasn't in the position of needing this at the moment, due to being on 5.2.0 and then using NiJuLe's bridge to move to 5.3.0.
However I've flashed it anyway, just in case I could bring any further information forward to help. Flashed without a problem and perfectly. Well, minor problem it took a few tries to get my finger to recognise, but the screen does say it might.
