Hi all,
i've recently bought a Nexus S which is a non-US/UK (GT-i9020) version having a SC-LCD screen (GT-i9023).
Which is not, sadly, the only difference...
MOD EDIT: This tutorial also applies to AT&T/Rogers/Telus variants of the Nexus S with SAMOLED screen (i9020A)
This tutorial is based on AllGamer's [GUIDE] Step by Step ROOT Nexus S via ClockworkMod Recovery image (i9020 only).
You're now free to install the ROM you want.
Have fun, take care !
