[Q] How to change firmware from asia to America

---

long story short; I'm planning on buying a Sam galaxy S II from china.
If I end up with a "asia region firmware", is it possible to change it to another firmware/region risk-free?

Edit:
also is it possible to unlock it in case it was locked?
thanks

It is possible to Unlock.
It is possible to flash any region firmware over any region firmware.

Regards.

Still the same i9100 phone, so you can put any firmware made for i9100.

Hi,

This is not working for me. I tried to flash XWKF3 over the ZCKG4 with Odin but that ended up in a brick phone. Got ZNKG5 downloaded and saved the phone but still on chinese firmware (with no app-market).

Have anyone done a firmware upgrade on a chinese SGS2? I would really like to get EU version with APP-market support, the phone is useless for me otherwise. (and I cant read chinese...)

Either you made a mistake when flashing the KF3 firmware by Odin or you flashed a wrong firmware. Make sure the firmware is full, it will be sized around 300 MB.

Regards.

Id just like to get my 2 cents worth in here so please correct me if im wrong,but ive been reading many failed attempts at this and heres what ive been thinking.

For example the galaxy s2 has this version that we have and also a 4G S2 released in canada.many galaxy models have 3G and 4G versions.Also we see Samsung releasing phones for for china or korea only.Is it possible that the Asian area also works on a different format frequency.For example an S2 firmware wouldnt be compatable with the 4G unit would it??.maybe the same type of thing is happening here cos i cant see anyone having any success with flashing between these two specific regions.Maybe there is a batch of chinese made phones made especially for the aisian region only because of this that makes it non compatable internationally like 4G- 3G regions.

from what i know the 4g s2 from canada is just a naming gimmick by the carrier there. it's still the same s2.

Ok, i read the other threads. apparently in this case failure is more common than success. so I guess I don't buy it in china.
