I was dubious about the utility of flashing K800i to K810i, this thread seems to prove I wasn't that wrong...
BUT I'm not that sure CID could bring any problem, when I tried XS++ the first thing I was proposed was to upgrade to CID52 !
Which I haven't done yet, I'm afraid it might set another problem for unlocking the handset (which was and still is my main problem).
I'd like some authorized opinions.
For instance, could bennyboi45 be more specific about the FSX settings he modified?
Thx to all.
