Before I start the update is trying to download to my pc but fails
Now I'm not bothered I've already tried it and found it worse than GB
But this is to let UK members know with that SI Number that it is out but the update fails
Staff here yes it is out I locked my bootloader flashed back my recovery firmware hoping that the update would work so I could then create an FTF file for the members on XDA but it fails at Preparing Pc for software update then 2 thirds the way through it fails
Solved! Go to Solution.
FIRMWARE 6.1.A.0.453 UK (1257-3921)
If your PCC or SUS says no update and you want it then download from the link below and flash it yourself if you know how - Yes it's version .453 not .452 what everyone else is on but I see no difference and the issue with the wi-fi signal in my oppinion is still the same.
I'll keep it on my drive for a bit if members want it

dude i have the same SI number but still PCC shows your phone is up to date. BTW i've bought the phone from UK but now using it in india. May that be the reason for my PC companion showing no update?
Open the back cover - Your SI number is on there
try again

When i use SUS i get this error. Should i try later? While PC companion still shows no update.
I did that. Its the same SI number as yours.
Same here! SI 1257-3114
PC companion says it's up-to-date, and update service crashes as the screen grab above!
Im pretty sure that ICS isnt available yet in the uk. where did you get this info from may i ask?
From me - my SI number is as stated above and my PCC says it's available but like every member it fails
oh thats strange, mine is the same SI yet mine says up to date 
Thanks for getting back to me anyway
