I thought the Warranty is void once you've rooted the handset Tillaz?
Seems there is no UK firmware available to download for the Y300. There's also a B176 and a B182 UK firmware and the only place I found them is on Asanfile, where you have to pay a silly price to register. The UK seems to be the only place where Huawei don't distribute their firmware to the customer. Ridiculous.
