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 your convenience, we have also shown on how this custom ROM firmware looks like in your Galaxy SL I9003

  • Please make sure that you are not backing up the data with the below steps and not with the help of KIES PC suite. Ensure that you are not backing up the data with the help of PC Suite as it won’t detect the device in the custom ROM firmware.

SMS – Use “SMS Backup & Restore app”,
Contacts – Sync with the Gmail application,
Call Log - Call Log and Restore
Images, Songs, Videos, Files – Copy to internal / External SD Card,
APN and MMS Settings – Note down from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names

  • Also, the minimum battery life should be 60% or else device may get turned off in the middle of firmware update. Uninstall all the security tools installed in your phone. Head over to the path “Settings > Applications > Development > USB debugging”, enable the USB Debugging.
  • This firmware can only be applied to the devices which are rooted. To check, download the “Root Checker” app from the PLAY Store. Once the device is rooted, you will have to download the “ROM Manager” app too from the Google PLAY Store.

To root the device all you need to do is to just follow the below mentioned two instructions,

    I am not able to use my phone as Wifi hotspot but Wifi itself is working. Also I can’t connect it to my PC as USB mass storage, any solution for that? I have tried USB_mass_storage app to do that but failed. The phone charges when connected but PC can’t detect it.

    • Atinderpal Singh

      It doesn’t connect to windows but works fine with linux

  • bobby jadoun

  • kenny

    to have wifi, just press the settings button on wifi settings –> advance –> then press avoid poor connections (y)..
    I’m having trouble in texting, sometimes the signal just disappears and reappears when sending a text message..thanks

    • Arshad

      thank your brother. i was looking to fix this problem but now its ok.

  • kenny

    to have wifi, just press the settings button on wifi settings –> advance –> then press avoid poor connections (y)

    Dear Pradeep, I am having 2.3.5 presently installed on my galaxy s gt i9003. As per your instuctions I am trying to install 2.3.6 and then root file from android advices but link given is not working . Please help me …..

  • Adnan

  • arshad

    Hello Neel
    is there any future update to this firmware because i have wifi issue with this rom.


  • Nikhil Khadse

    A couple of issues Mr. Pradeep…
    1. I am not unable to mount my external SD card. Please guide me as to how can i do that?
    2. Wifi and tethering does not work. I need these functionalities the most, please suggest a way to make these work.

    Your guidance will be much much appreciated. Thanks in advance.

    • Pradeep Neela

      have you rooted the device?if yes then you need to mount the same via rom manager

  • darknight

    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.

  • Rocky

    Sometimes the touch does not work. So, i have to press the power key to lock and then unlock to make the touch work.

  • Anmol
