Cannot update unlocked galaxy s II

Hello,
I have unlocked my galaxy S II (which was locked to virgin mobile Canada). When I connected it to kies, it still shows that I have the latest firmware (2.3.3) which is not true :| I thought kies would allow unlocked phones to be updated.
Can someone tell me where I am going wrong :|
Model: GT-I9100M
Android: 2.3.3
Baseband version: I9100MUGKG2
Buildnumber: GINGERBREAD.UCKG2
Sorry for asking such dumb question but I am new to this forum (a.k.a noob )

Note 4 Upgrading help

I have the SM-N910A variant Note 4 on Cricket wireless (AT&T prepaid subsidiary) I have been informed that I am several versions behind on my OS but have yet to find a thread that can get me up to date since the OTA won't work for me.
Is there a way to get up to date with Odin or Kies? Or at least get enough up to date that Smart Switch will handle the rest?
Here are my specs:
Android Ver:
5.1.1
Baseband Ver:
N910AUCU2DOI2
Kernel Ver:
3.10.40-5613584
