How to Update Galaxy SL I9003 with Jellybean 4.1.1 Codename 3.5.0 Firmware

Samsung Guess LogoSamsung Galaxy SL GT I9003 users have now no reason to feel left out in the race of ICS or jellybean 4.1.1, though Samsung has no plans to come up with any of these two latest firmware upgrades, all thanks to the custom ROM firmware makers who have come up with various custom ROMs which have optimized the jellybean 4.1 firmware to align itself with the Galaxy S GT I9003 device. Over a period of this article we will be checking out on how you can install the latest version of Codename Android 3.5.0 firmware in your phone which is based on the latest Jellybean 4.1.1 firmware.

    For all those who are getting the ‘Temporarily avoiding poor connection issue’, it looks like a setting that is defaulted to on bootup. To solve this, go to ‘Settings > WiFi > and then the settings again to ‘Advanced”. You’ll find the ‘Avoid poor connections’ option checked. Uncheck it and you should be good to go.

    But i have other issues with this ROM:-

    1. Stock alarm doesnt work . I can hear it go off but i can’t dismiss or snooze it. Using Alarm extreme App for now.

    2. Battery life isn’t the greatest. But not sure if its a hardware compatibility issue as JB wasnt designed for i9003 anyways.
