The Samsung Galaxy Y S5360 is one of Samsung’s very popular entry-level Android handsets.  When it was first released into the market, it originally came with Android 2.3.5 Gingerbread.  But, Samsung has already released an official update for the device, which will bring the phone’s firmware to Android 2.3.6 Gingerbread.
Also referred to as build DDLA1, the firmware update ties up some of the loose ends in the original firmware build that came with the Galaxy Y when it first came out.  So, even though the new version is not as exciting as Android 4.0 Ice Cream Sandwich, it may be worth updating your Galaxy Y with it.
This firmware update build DDLA1 for the Samsung Galaxy Y S5360 should not be applied if you have a phone which is network-locked. Doing so might cause damage to your phone or could brick your phone.  Updating your handset to this firmware build will also make you lose root access (if you’ve previously rooted your phone).
