Samsung Galaxy SL i9003 Jelly Bean 4.2.2

If you're the owner of a Samsung Galaxy SL i9003 mobile phone, the bad news is that Samsung will not be updating it beyond Gingerbread 2.3.6 DDLF2 officially.

The Good news is, there are a lot of options to update it to Ice Cream Sandwich and Jelly Bean, though unofficially. Please note, updating this phone to CM9, CM10, or CM10.1 will void your warranty as these are unofficial ROMs. In this article we will update the phone to Jelly Bean ROM called CyanogenMod 10.1 Alpha 2.
