Keep in mind that if you lose your CID there is NO WAY BACK from 982.124.14.XT910.Retail.en.EU as it brings along a locked bootloader (as far as I know!).
In fact I mistakingly flashed that to try it and replaced my China version (and kernel too!!!) and now I am hopelessy stuck into this system & kernel version!
I managed to flash the Retail British ROM on my Asian device using RSD Lite. But I seem to find cell signal a bit weak, anyone else having this issue?.
