Samsung Galaxy S2 LogoSo, after the Galaxy S which recently got a fresh new update of Gingerbread 2.3.5 you too might have expected a 2.3.5 Gingerbread release for your Samsung Galaxy S2 but you will need to wait further more. But before that an all new firmware update in the form of XWKH4 has arrived which is basically a Gingerbread 2.3.4 leak. Though we don’t have an exact change log on what’s changed and what’s not, we can only guide you on how you can update the same on your Galaxy S2 Phone. So, in the due course of this update we will check out the same.

Please note that anyone with their Samsung Galaxy S2 GT I9100 can proceed with this article to update their phones with this Gingerbread XWKH4 release as it’s a global beta release. It’s not recommended to update this firmware on the network locked phones as this may unlock or do damage to the phones which may or may not be a reversible process.

Note: Strictly all the mentioned instructions needs to be followed which are mentioned in the due course of this article or else you may end up bricking up the phone.

Of late it has been found that users select different options like the “Re – partition” etc. which should not be done until and unless mentioned in the article. Many users brick their phones by not following the instructions.

    and is there any major changers (additional apps, improve the market apps, support the Arabic language ) or only minor changes?
