When I did the first flash of euro open Kit Kat had a few errors and flashing stopped, but being a season rom glashet on S2 and S3, etrors and bad flashed did not phase me so carried on and the flash eventually went through and I had a good flash on my phone.
However I as getting a lower signal than before, very poor at home where it was excellent before, so when the UK open came up I downloaded it, and have just had chance to flash it.
However, the phone seemed way ahead of the LG support tool on the laptop, and had finished and restarted while the support tool said 70%, I left it till the tool had finished though.
I have attached picture, is this the UK open that has flashed onto the phone. I'm still getting poor signal on the phone, but putting into S3 the signal is perfect!
